Through the senses of the Glazed Cold Crystal Snake, Yang Fan could also blur the sight and gained a certain understanding of the situation in the castle.

Six days later.

The attacks of the righteous cultivators were constantly on the rise. Under the influence of Yang Fan, the miraculous doctor, the five teams could be almost completely damaged.

The power of the ancient strange formation around the castle has been weakened by 40% or 50%.

During this period, Yang Fan didn't know how many cultivators he had treated, and his cultivation level continued to improve, and he faintly touched the state of the middle stage of foundation building.

On the seventh day, a sudden change occurred, and the ancient strange formations around the castle shone brightly and returned to its peak state.

"What!?"

This situation makes the leader of the alliance's forces look very bad.

"I didn't expect them to replace the spirit stones so soon."

Le Bo said with a little regret.

"I had to continue attacking..." Meng Xuan said expressionlessly.

"How many people have you controlled?" Le Bo sent a voice to Mengxuan's spiritual sense.

"The ancient strange formation has half the resistance to spiritual magical powers. With the distance limitation, it is quite exhausting to use the "Dream Heaven Technique". So far, I have only controlled two warriors."

Meng Xuan replied.

"Okay, keep working hard and let the people you are under control pay attention to it carefully then." Le Bo nodded.

"It's a pity that the two warriors I control are not the top leaders of the natives. If I can control a congenital warrior, things will be easier. Because among these indigenous people, there are very few innate warriors and a high status. It's a pity that I want to control a congenital warrior, I'm very trapped."

Meng Xuan said with a little regret.

On the eighth day of the alliance camp siege, a sudden change occurred.

Whoosh swish swish swish-

Several huge crossbow arrows about meter long shot through the air, and the powerful wind blew through the sound of a loud and harsh sound in the void.

puff!

A monk's shoulder was pierced and fell into a pool of blood. Another monk's low-grade defensive spirit weapon was broken through a crack.

"What a terrible attack!"

Yang Fan was secretly shocked, and Le Bo and others also changed their expressions.

I saw that there were four or five huge siege crossbows on the city wall at some point.

This crossbow is not the kind in the secular world. It is also carved with strange and complex patterns and formations. Whenever it is activated, a flash of inspiration appears.

Yang Fan showed a strange look on his face, and he also saw another feature of this ancient formation. Cultivators cannot use magic power in it, but machinery or dead objects like puppets that rely on spirit stones are not restricted.

"Retreat first, Yaoshi Yang comes and save people."

The three leaders quickly issued orders.

Soon, the team of monks retreated and Yang Fan rushed over to rescue him.

Fortunately, every time the crossbow cart fires, it will have to reinstall the crossbow arrows, which will have enough time to retreat.

Yang Fan checked the injured person and couldn't help but take a breath of air. His entire left shoulder was penetrated, and the monk was almost on the verge of death.

Fortunately, Yang Fan, a miraculous doctor, was in charge and cured his injuries.

After Yang Fan completely cured the injuries of the monks... he was suddenly stunned and then showed joy.

After so many days of continuous treatment, he unknowingly advanced... to the middle stage of foundation building.

The middle stage of foundation building...

Yang Fan took a deep breath. With this trend, he still had room for further improvement in the Nine Netherworld Secret Realm. The untouchable high-level level seemed not so far away.

At this moment, Le Bo held a huge crossbow arrow set up from the city tower, and his face was shocked:

"The materials used for siege crossbow arrows have exceeded the level of spiritual weapons and are several times harder than my top-grade spiritual weapons. This is probably the material for refining magic weapons."

When everyone heard this, they were filled with joy. What was worried was that the power of the siege crossbow arrows was, and what was joy was that the treasures in this colorful castle were larger than they thought.

Under such temptation, several leaders looked at each other, and their eyes were filled with excitement and expectation:

"Attack, the next team, give me a fierce attack!"

"Attack, the next team, give me a fierce attack!"

The appearance of the giant siege crossbow not only did not dispel the invasion of these foreign monks, but instead made them even more greedy and crazy.

The next team to participate in the battle is the Yuwen family.

"Everyone is scattered in the air and takes a wandering attack, beware of the attack of the siege crossbow arrows."

Yuwen Rou began to direct everyone to launch an attack, moving constantly in the air, floating in a vague manner.

Swallows!

In this way, the threat of siege crossbow arrows is smaller, and at least it is not easy to be killed instantly.

Dingding bang bang...

The attacks continued, and in the middle, several monks were injured, all of whom were cured in time by Yang Fan.

In Yang Fan's words: As long as I have a breath, I can bring you back to the gates of hell.

His treatment speed is amazing. No matter how serious the injury is, it will only take a short time. As for ordinary minor injuries, it is just a breathing effort.

Invisibly, Yang Fan's existence reduced the mortality rate of the casual cultivator camp to the lowest point.

Since he joined, no monks in the five teams have suffered casualties, and they are not even disabled. Even if they have broken bones, broken arms and hands, Yang Fan can use the "Jade Bone Technique" to cure them in a moment.

Le Bo and three other strong men in the Foundation Establishment Stage were amazed at Yang Fan's methods, and were also surprised by his healing speed and sustainability.

They vaguely discovered that Yang Fan was very active in treating injuries and was completely silently dedicated to no return.

The monks who participated in the war also knew the existence of Yang Fan, so they tried their best to avoid fatal injuries during the battle. They understood that as long as they were not killed instantly, they would not be afraid of any serious injuries.

As time goes by, the attacks of the monks are unambiguous, and the power of the colorful castle's moat formation is also slowly decreasing.

After a few days, the formation power of the colorful castle was about to be weakened to 50%.

Through the last experience, they learned that when the power of this ancient strange formation was weakened to less than 50%, the natives would replace them with spirit stones.

At this moment, both Yang Fan and the three leaders in the camp of wandering cultivators were very energetic.

"Are you ready?" Le Bo's divine consciousness transmitted a voice.

"I have controlled four indigenous warriors, and they are paying close attention to the dynamics in this regard." Meng Xuan said with a smile: "I think we will soon find the central hub of this ancient strange formation."

"I hope this is the case." Le Bo sighed softly: "Time cannot be delayed for too long, otherwise this place will eventually be discovered by other forces."

At the same time, Yang Fan sensed the actions of some high-level leaders in the castle through his connection with the "Glass Cold Crystal Snake".

"Senior Le, someone suddenly disappeared in the camp."

A cultivator from the Qi Refining Stage came to report.

"What? Someone is missing?!" Le Bo's expression changed drastically. He picked up the man and said fiercely: "What the hell is going on?"

"Senior... I don't know very well. Judging from the situation, he probably left within the past two days. Before that, he was a formation master and did not participate in the battle."

The Qi Refining Cultivator said tremblingly.

"Bang!"

Le Bo looked gloomy and kicked the Qi Refining Cultivator out of the camp.

"There may be traitors in our camp of wandering cultivators." Le Bo said to Meng Xuan and Gao Badao: "We must speed up the plan. If other forces are allowed to penetrate, it will be troublesome."

Half a day later, Meng Xuan suddenly said, "There is some movement..."

"Huh? They seem to be heading in eight directions..."

Meng Xuan showed a look of surprise on her face.

"Eight directions?" Le Bo was slightly stunned, "It seems that the arrangement of this ancient strange formation is quite complicated. Since there are eight directions, it is definitely necessary to replace the spirit stones in eight directions."

"This is a troublesome..."

The two frowned, but the burly man Gao Ba did not participate in this strategy.

...

"Not good! Other monks are coming here, as if they were demon monks..."

At this moment, another monk came to report the message.

"What? Demonic monk!"

Le Bo's expression condensed, he expanded his spiritual consciousness, and looked into the distance.

I saw dozens of monks flying on the other side of the colorful castle, one by one, with murderous auras and demons.

"That's...the devil's scattered cultivators' camp!"

"All monks participating in the war should withdraw quickly and quickly!"
To be continued...
