The latter is a second-level mid-grade elixir for restoring mana. It can be taken during a spell fight and can be converted into mana without special refining.

In a very short period of time, it can restore one-third of the mana below the peak of foundation building, which has extremely high practical value.

In fact, there are many mana-restoring elixirs on the market that can also restore mana quickly, but they have various flaws and limitations. The biggest limitation is that they require active refining.

But in the midst of a fierce battle, how could the enemy cultivator give this time to refine it?

Therefore, the mana-restoring elixirs on the market are too limited, not very practical, and not very expensive.

But Zizhidan is different. It can restore mana during the battle, which is equivalent to one-third more mana than a monk of the same level, which is equivalent to enhancing the strength in disguise.

If two monks are in a fierce fight, one has taken the Zi Zhi Dan, and the other is slowly absorbing the spiritual energy from the spiritual stone, it is self-evident which one will be exhausted first.

Therefore, although only one elixir like Zizhi Dan can be taken within three days, it is definitely a rare treasure for monks who are about to go to the battlefield. It may be able to kill powerful enemies at critical moments.

With this elixir in hand, Liu Yu would not have to worry about not being able to exchange for what he needs.

He calmly touched the two elixirs in the storage bag. Originally he just wanted to refine a few bottles for later use, but unexpectedly the value suddenly increased so much that he had some expectations for this exchange meeting.

Moving slowly, stopping for a while from time to time, Liu Yu glanced at the stalls along the way and carefully selected the items placed on them.

The most sought-after items now are undoubtedly all kinds of things that can increase strength, such as powerful talismans, powerful magic weapons, talismans made of magic weapons, etc.

In contrast, various raw materials such as spiritual herbs and elixirs, Qi refining materials, formation materials, etc. are obviously "deserted".

The price of the former has gone up two or three levels and there are still monks buying it, but the latter is being sold at a somewhat low price at this time.

This time Chu and Qi attacked Yan together and had an absolute advantage in strength, but all the monks had no intention of taking it lightly.

The State of Yan is also one of the "Nine Great Countries". It is larger than the State of Chu in terms of size, and it also has the home field advantage.

Although no monk thinks that it can withstand the alliance's attack, some casualties are inevitable, and the casualties may even be heavy. This is the consensus of all monks.

No monk wants to be one of the "casualties", so they are trying to increase their strength as much as possible, and some even take out the treasures at the bottom of the box.

Liu Yu wandered among the various stalls, searching eagerly for what he wanted. He accepted all the spiritual herbs that were not available in the Immortal Mansion, and collected them all in a low-key manner.

Although he had the two "magic weapons" of Black Jade Intermittent Pill and Purple Zhi Pill in hand, he did not take them out easily and only used them when exchanging some rare spiritual herbs.

If it is just ordinary spiritual grass, try to exchange it with common things such as spiritual stones, cultivation elixirs, etc.

Black Jade Intermittent Pill and Purple Zhidan are two spiritual elixirs. The age of refining the spiritual herbs is close to the 500 years that Golden Elixir monks can use. For most foundation-building monks, they are out-and-out high-age spiritual herbs.

.

Even a second-level alchemist who is highly skilled in alchemy may not be able to collect a few refining materials in his lifetime, let alone refining them in large quantities.

If it suddenly leaks out in large quantities, it will definitely attract the attention of some monks.

Liu Yu would certainly not do something like this that might expose the secrets of the Immortal Mansion.

Therefore, it was only used as a bargaining chip in the exchange of rare spiritual herbs, and in order to prevent frequent transactions from attracting the attention of interested people, he left several times in the middle and changed into the costumes of disciples of other sects to conduct transactions.

It wasn't until I finally looked at all the stalls and was no longer ready to take action that I put on my original appearance and reappeared at the exchange meeting.

A bearded man, a muscular man, and a lean old man. Unbeknownst to the monks, he changed his appearance, body shape, and clothing, sweeping away the spiritual herbs inventory of the monks in the field.

Of course, these spiritual herbs and elixirs are not available in the Immortal Mansion, and a maximum of two of each species can be purchased symbolically.

There were no monks in the exchange meeting who specifically identified themselves, and anyone who was a monk from the Five Sects could participate, so no one noticed Liu Yu's "little move".

Time passed slowly, and after a few hours, the monks here left one after another, and the number of people gradually became fewer and fewer.

Liu Yu also took Jiang Qiushui back to the cave where she temporarily settled, collected her harvest, and said goodbye to the woman regardless of her resentful eyes.

In the cave, he waved his sleeves and more than thirty jade boxes appeared on the table.

Looking at these jade boxes, Liu Yu showed a smile on her face.

In one operation, thirty kinds of spiritual herbs were harvested that were not found in the Immortal Mansion, as well as four kinds of spiritual herbs used to refine gold-forming elixirs. It must be said that it was a big surprise.

"Now that we have gathered the spiritual herbs for refining the Yuan Sheng Dan, we can start refining it sometime."

"Moreover, we have collected less than half of the spiritual herbs needed to refine the other two elixirs, which saves a lot of effort at once."

This thought flashed through Liu Yu's mind, and she couldn't help but look happy.

Sheng Yuan Dan, like Jing Yuan Dan and Yang Yuan Dan, is the most common cultivation elixir in the foundation building stage and is suitable for monks in the later stage of foundation building.

The prescriptions for these three kinds of elixirs are relatively easy to obtain. Many second-level alchemists have them in their hands, and they are also available in the Yuanyang Zong Sutra Pavilion. You only need to reach a certain level of cultivation and spend some spiritual stones to restore them at the upper level of the Sutra Pavilion.

Just click it.

"It's a pity that even talisman treasures appeared in this exchange meeting, but there were no top-quality defensive spiritual weapons."

Liu Yu thought with some regret.

With his current state, he can already exert most of the power of the best spiritual weapons. He already has the Molten Knife for attack, but he still lacks one of the best spiritual weapons for defense.

If a configuration of one offense and one defense can be formed, both strength and self-protection will be greatly enhanced.

If a high-quality defensive spiritual weapon really appears at the exchange meeting, then it would be worthwhile to make a high profile and take some risks.

As for the talisman treasure, he was not very keen on it and had no intention of taking action for it.

Without him, there are already three talismans in the storage bag, namely the Snow Silk Needle Talisman, the Diamond Halberd Talisman and the Purple Bell Talisman.

Among them, the remaining power of the Snow Silk Needle Talisman and the Purple Bell Talisman can only be used once, while the remaining power of the Diamond Halberd Talisman can be used exactly twice.

With Liu Yu's current level, it is already the limit to offer two talismans at the same time. But now he has three talismans in his hand. Even if he adds one more talisman, he will not be able to increase his strength much.

Therefore, there is no need for this at the moment.

Next, he checked the harvest and sorted out the magic weapons, spiritual weapons, talismans, etc. he currently owned, as well as the various means he owned.

The magical weapons include: Zimu Soul Chasing Blade, Sharp Gold Sword, Shining Gold Bow, Thick Earth Sky Umbrella, and Escape Wind Boat.

The spiritual weapons include: Li Xuan Sword, Green Dragon Halberd, Netherworld Soul-Severing Cone, White Snow Whisk, and Molten Fire Knife.

In terms of secret techniques, there are Qingyang Demonic Fire, Shocking God Thorn, and in terms of talismans, there are three golden wind scattered talismans, a dark extinguishing fire meteor talisman, an instant thousand-mile talisman, and three Yin Lei Zi.

Plus three talismans.

Liu Yu tried all the methods, mentally evaluated the approximate power of all methods, and what method was suitable under what circumstances, and had a rough idea of ​​his own strength.

With the pure magic power of Demon Fire Refining Elements and sophisticated spiritual weapons, he is estimated to be able to defeat ordinary late-stage foundation-building monks without holding anything back.

If all the trump cards are used, it is possible to defeat two late-stage foundation-building monks at the same time, but there is still a long way to go compared to the top monks in the foundation-building realm such as the Three Heroes and Four Heroes.

His current strength is different from that of Changfeng Zhenren's personal disciple Li, so the gap should not be very big.

Of course, this is under the condition that its strength has not improved much compared to the past.

However, this is only Liu Yu's preliminary estimate after all. It can only be used as a reference and cannot be used as a basis for action. Otherwise, he will surely die.

Apart from anything else, if you have a trump card, other monks cannot have trump cards?

The gap between large realms represents a huge difference in strength, but the gap between small realms is not insurmountable.

A monk in the same big realm who is in a higher realm is not necessarily better than a monk who is in a lower realm. It depends on the individual.

Realm can represent strength, but it cannot completely represent strength. Otherwise, when fighting, it would be enough to compete with realm.

Liu Yu divided the strength of the foundation-building monks into three levels in his mind, and only considered their true strength.

They are ordinary monks, elite monks and top monks.

Ordinary monks are average in strength at the same level, they don't have particularly powerful secret techniques or methods, and their performance is quite satisfactory.

Such as Yan Kai, Cui Liang, Jiang Qiushui, etc., compared to other foundation-building monks in the sect, there is nothing outstanding.

Elite monks are considered to be the best. They can defeat ordinary monks relatively easily. They usually have practiced extraordinary skills and possess good magic weapons and spiritual weapons.

For example, Li BuTong, whom I have met before, is one of the best among the elite monks. He probably practices top-level skills and possesses top-grade spiritual weapons.

As for the top monks, they refer to the Three Heroes and Four Heroes, the Six Sons of Hehuan, and the Seven Swords of the Waning Moon. They have real achievements and no obvious shortcomings in all aspects.

When facing ordinary monks and elite monks, they can often outnumber them and even defeat them head-on. It is a majestic crushing!

However, the strength of the monks in the late stage of foundation building is obviously much better than that of the monks in the early and middle stages. In comparison, it is indeed "not ordinary". It is not appropriate to say that they are ordinary monks.

Moreover, being able to cultivate to the late stage of foundation building is considered excellent in the realm of foundation building. It is not an exaggeration to say that he is an excellent monk.

Ordinary monks, outstanding monks, elite monks, top monks.

This is the division of strength of monks in the foundation-building stage in Liu Yu's mind. Every time he comes into contact with a monk, he will subconsciously think about the level of his strength.

Of course this is not rigorous, it is just a classification based on his own standards, and he has no intention of telling others his standards.

According to this set of standards, Liu Yu feels that his strength is probably at the elite level, and he is already considered a very small minority in the foundation-building realm.

If you want to protect yourself in the upcoming battle of the Yan Kingdom, if you want to collect spiritual grass seeds and search for various resources in the Yan Kingdom, given your current strength, you only need to keep a low profile, and the feasibility is still very high.

As long as you are not unlucky enough to encounter a Jindan monk, or be attacked by many monks of the same level, you can still have a good chance of saving your life by relying on various trump cards.

Chaos is the ladder to ascend!

It was precisely because of the growth of his own strength that Liu Yu started to think carefully and wanted to seek benefits in the next chaos!

After sorting out the contents of the storage bag, I put the harvested thirty-four spiritual herbs into the Immortal Mansion, and used my magic power to carefully warm up the magic weapons and spiritual weapons. Two or three hours have passed.

Liu Yu took out the book of Baicao Dan again and started to read it.

…

Two days passed in a flash, and the atmosphere on Kongsang Mountain was calm and depressing.

The caves of the Yuanyang Sect's one hundred and fifty foundation-building monks were not far from each other, and they usually communicated very frequently. However, there was no relaxed expression on their faces, and their actions were full of solemnity and depression.

Liu Yu, Jiang Qiushui, Yan Kai, and Cui Liang were also sitting opposite each other in a small pavilion, talking about what was about to happen.

"According to Cui, our attitude must be tough when facing the Immortal Cultivation Family of Yan State!"

"Some cultivating families have inextricable connections with the four major sects of the Yan Kingdom, and they are even the disciples of the sects who go out to spread their branches."

"When the senior officials of the four major sects in the Yan Kingdom are confirmed to have been bribed and controlled by evil spirits, it is difficult to say that they have no problems."

"We should rather kill a thousand by mistake than let one go."

"Otherwise, it must be a big hidden danger, which may lead to a large increase in casualties!"
