Before, he had been thinking about how to eliminate the two demonic lights, but because his Taoist foundation was made of Taiyi sword energy, the most god and holy, and he could not tolerate a trace of filth. But if all the filth in these two demonic lights were eliminated, only demonic power was left? Can it be used for himself?

Lin Fei thought about the seven sword energy in his body. Except for the Taiyi sword energy and Xiri sword energy, the other sword energy have their own different auras, like Tonggu Sword Energy, which can cut Yin and Yang with one sword and become a bridge of space. The sword energy of Lei Yu is condensed, and a wisp of five-color ice evil is melted into the cloud pattern sword energy...

These two demon lights are both powerful and have magical powers. If they remove all the filth in it, extract their power, and inject them into the seven sword energy, it is more perfect than completely erasing them.

If you want to get rid of its filth, ordinary elixirs have no effect. The best choice is to use Nine Yang Pill.

The so-called Nine Yang Pill refers to the elixir obtained by starting the furnace with the true fire of the sun, using nine kinds of worldly yang spiritual medicines as the leads, and refining hundreds of spiritual herbs. If this elixir is placed in the world of immortal cultivation, it can be worth hundreds of thousands of spirit stones. If the nine kinds of introductions are more expensive, such as using the Fiery Sun Purple Pattern Fruit, the price will be increased again.

When Lin Fei was in Wanghai City, he almost swept the treasures there. He packed several Qiankun bags. It was not difficult to find hundreds of spiritual herbs. The real fire of the sun can also be replaced by Xiri sword energy, but the yang spiritual medicine was missing two...

"In addition to the Nine Yang Pill, if you want to introduce the power from the two demonic lights into the sword energy, you also need some demonic pills."

Lin Fei shook his head. Along the way, he and Sun Qing killed countless monsters, but those demon pills were either destroyed by sword energy or thrown into the underworld to nourish all things, and there was nothing left...

"Tsk, it's a waste..."

Lin Fei sighed and left the underworld. He rethinked his thoughts, taking into account every detail and possible dangers. After a brief passage, he made a decision in his heart.

No one has ever walked through the path to enlightenment with the ten thousand swords of the heavens. If he is no longer able to move forward, he will not talk about enlightenment and becoming an immortal.

After reinforcing the Hunyuan Sword Formation in his body again, Lin Fei woke up Sun Qing beside him: "It's time to do work."

"Um?"

Sun Qing's injuries were healed. When he heard this, his subconscious reaction was that the people from the Three Demon Sect were chasing him, but when he looked around, it was empty and quiet, not like someone.

Lin Fei stretched out his hand and took back the Wuchang sword energy, protected the two of them, and covered the breath. At the same time, the four swords of the evil star and the ferocious sword box also returned.

Sun Qing looked at him and was puzzled: "Where are we going now?"

"Go and find something."

In the Ten Thousand Form Immortal Cave, there is a vast and cold area. The layers of ice ridges of icebergs stagnate in the air like solidified waves, ferocious and strange. There is no sunshine here all year round, and the coldness condenses, and it penetrates into the bone marrow. Not to mention the most yang and strong spiritual medicine, you can't even see a trace of Mars.

However, when Lin Fei was entering the Ten Thousand Formation Immortal Cave, he saw several large flame formations and even picked a thousand-petal red flame fruit. This kind of spiritual medicine that has always lived inside the volcano, in this cold world, there are still flames flowing in the rhizomes, and he still lives well.

Lin Fei released the Tiangui, told it the characteristics of the spiritual medicine he needed, and let it take the lead.

The ghost shook his head and floated forward like drunk...

Lin Fei knew that this guy was stealing spiritual herbs in the underworld. Now that the medicine power is rising, he feels a little fluttering. He immediately said coldly: "If you ruin my business, you will feed you to the evil ghosts."

When Tiangui heard this, he smiled flatteringly twice, patted the ghost's spirit and said that there was no problem, and then continued to move forward...

Seeing that Lin Fei was walking on the way they came, Sun Qing frowned: "There must be many people from the Three Demon Sects waiting for us..."

"How can I get a tiger's son if I don't enter the tiger's den?"

Lin Fei said lightly, not looking very worried, and took Sun Qing's Three Dragon Huanyue Sword while the Tiangui was looking for the spiritual grass.

The branches of the Dragon-patterned Sacrificial Fruit Tree have been refined by Zhutian Futu. The branches are like gold and iron, strong and tough, not worse than the fourth-grade acquired Divine Iron. After being refined, they turned into mist-like powder, wrapped in the trace of dragon energy in the branches, and slowly sank into the giant knife.

It seemed as if it was under a powerful force of true energy, the giant sword was shaking greatly, and the thirty-six prohibitions seemed to be surrounded and restrained by an invisible force. The three giant dragons, red, black and gold, roared together, and intertwine and entangled together...

After the branches of the entire dragon-patterned fruit tree were absorbed by the giant sword, Sun Qing's natal weapon, thirty-six restrictions, finally perfectly integrated, and achieved magic weapon. The souls of the three giant dragons merged together, and the dazzling light dissipated. The heavy blade body turned into a long dragon covered with red and black scales. It seemed to be poured by iron, with a cold light, three claws soaring in the air, and its mightyness. The horns of the two dragons were light golden and had not yet been fully formed, but the body of this long dragon was as sharp as a blade.

Because there are the impermanent sword energy and the four evil swords that enclose the space, no matter how big the long sword in Lin Fei's hand is, it has never been spyed by the outside world.

Sun Qing looked at the roaring dragon in the sky. It seemed as bright as two stars fell in his dark eyes, and it was hard to hide his joy. With a thought, the long dragon turned into a giant sword and fell down again. When he held it in his hand, there had been a lot of changes. The appearance of the three giant dragons had disappeared, and the entire blade was lying like a red and black dragon. The blade was restrained and should not be underestimated, and it was even more in line with its intentions.

"Finally..." Sun Qing was full of excitement, but he was still suppressed. He looked at Lin Fei with a serious expression and bowed: "Senior Brother Lin, thank you."

Lin Fei waved his hand and didn't feel at ease about this matter. He walked forward and said, "You are following me now, just like a combat pet, and your combat power is too bad."

“…”

Damn...

What is fighting pet? Comparing me to those monsters...

The gratitude on Sun Qing's face was a little deformed before it even faded.

The two of them followed the footsteps of the sky ghost and were turning a ridge of ice, by chance, they met two disciples of the Three Demon Sects.

The moment the four of them faced each other head-on, they were all quite surprised.

The two disciples looked in their thirties, wearing the Taoist robe of inner disciples. When they saw Lin Fei and Sun Qing, they were obviously not mentally prepared. They first saw a mass of ghost energy attacking, and then they saw the main master who was being chased by them, and then subconsciously shouted.
