Fat Yue left, taking the list of spiritual grass that Wu Xin listed for him.

In order to prevent others from seeing the clues, Wu Xin listed hundreds of spirit grasses for Yue Fatzi, and among these hundreds of elixirs, there were only more than ten kinds that could be used in the Ruiyi Pill.

To refine the Ruiyi Pill, a total of one hundred and seven kinds of spirit grasses of all levels need to be used, except for the dozen or so spirit grasses that Yue Fatzi purchased, the rest of the spirit grasses are all in Wu Xin's space ring.

After seeing Fat Yue leave, Wu Xin waved at Da Hei and motioned for him to follow.

In fact, if Da Hei hadn't given the Dan Fang of Ruiyi Dan to Wu Xin, it would have returned to the core place a long time ago, after all, the core place is where the real cave heaven blessed land of the demon clan like it is.

Yue Fatzi's departure is to leave for two years, and at his current speed, it will take half a year to rush back to the Seven Holy Cities from the inner perimeter.

This time and again, it will take a year, plus the time to collect spirit grass, two years is already his limit.

"Boss, you don't have to send it anymore, with my current strength, there will basically be no danger. ”

"Hmm. Hearing this, Wu Xin nodded at Da Hei, and then stopped.

"After you go back, give them a little bit of those pills, your strength is still a little weaker now. ”

"Don't worry, boss, I won't miss them. ”

"Well, let's go, remember to be careful all the way, by the way, no one can say anything about that!"

"Don't worry, boss!"

In the past two years, Wu Xin has refined a total of hundreds of furnace pills, and among these pills refined, although there are no sixth-order pills, most of them have reached the fifth-order upper grade!

That's right, Wu Xin was preparing the elixir for cultivation for the big black pills, and at the same time honing his alchemy, he wanted to prepare for refining the Ruiyi Pill.

Yue Fatzi just came back two days ago, as soon as he came back, Da Hei proposed to leave, and it had been out for a long time.

The Ruiyi Pill was of little use to these demon cultivators, and after Wu Xin came back from Yue Fatty, his attention was directly focused on studying the Danfang, so after hearing that Da Hei was leaving, he didn't keep it longer, but gave it all the pills he had refined before, and then sent it away.

"Fatty, you and Xiaoxue are guarding me outside, if someone comes, you must notify me in advance!"

In the inner perimeter of the Seven Saints Mountain Range, halfway up a thousand-zhang high mountain, Wu Xin said to Yue Fatzi and Xiao Xue with a serious face.

"Don't worry! Under my nose, rats don't want to get close to this cave!"

Buzzing~

Little Blood also flapped its wings twice.

"Well, then I'll go in, remember not to let the monster beast or anything bother me!"

"Hmm. ”

After confessing to Yue Fatzi, Wu Xin turned his body and entered the cave behind him.

This cave was originally the lair of a fifth-order demon bear, but that guy was very unlucky, and now he has gone to accompany his ancestor.

After Wu Xin and his entourage occupied this cave, they made a big change to the inside of the cave, and now the cave, except that the entrance of the cave has not changed, the interior has been expanded several times.

After entering the cave, Wu Xin's hand flashed with a flash of inspiration, and the Nine Snake Furnace was taken out by him.

Sitting in front of the furnace, Wu Xin took a deep breath, opened his mouth and spit out, and an almost transparent flame was spit on the bottom of the Nine Snake Furnace by him.

In Wu Xin's hands, he now has a total of four different fires, ranked from low to high, in order of Xuanhuang Yan, Qinglian Earth Heart Fire, Sea Heart Fire, and Fallen Heart Fire.

That transparent flame is the Falling Heart Flame!

After half a burnt incense, Wu Xin stretched out his hand to test the temperature of the furnace at the mouth of the Nine Snake Furnace, and after feeling that it was almost there, Wu Xin swept his sleeves, and hundreds of large or small uncovered jade boxes appeared beside him.

After going through the key points of refining the Ruiyi Pill in his heart, Wu Xin began to really refine it.

The first step of alchemy, dealing with the medicinal materials, and deciding to refine it, Wu Xin's eyes froze, and then he saw him grab those jade boxes, and a fist-sized red spirit fruit appeared in his hand.

Puff~

After holding the spirit fruit, Wu Xin pinched it, and the red spirit fruit was directly held into a ball of juice by him, and then, these juices, without dropping, were thrown into the Nine Snake Furnace by Wu Xin.

Zizi ~ Zizi ~

The moment the juice entered the furnace, a thick white mist rose from the mouth of the furnace......

Three days later.

Burst~

A muffled sound suddenly sounded from the Nine Snake Furnace.

After hearing this muffled sound, Wu Xin's face changed suddenly, and then, Wu Xin hurriedly got up and looked at the furnace.

As a result, Wu Xin's complexion turned black suddenly, because Lingye, who was still in the furnace before, had turned into a furnace of black slag at this time.

The first attempt of Ruiyi Dan undoubtedly ended in failure, and this time, Wu Xin didn't even enter the second step of alchemy, Rong Dan!

Ignoring the residue in the furnace, Wu Xin directly closed his eyes and recalled.

After a long time, Wu Xin's eyes lit up, and after quickly dealing with the Nine Snake Furnace, Wu Xin began refining again.

Four days later.

Burst~

A puff of black smoke came out of the small hole in the lid of the stove......

Eight days later.

Bang!

The Nine Snake Furnace was directly blown to pieces! Even Wu Xin himself was also injured this time.

However, Wu Xin was not discouraged by this, but had a posture of becoming more and more defeated.

After spending two thousand integrity points to repair the Nine Snake Furnace, Wu Xin refined it again.

Half a month later.

This time, there were no accidents on Wu Xin's alchemy journey, but when he was dividing the pill, he was careless, causing a ball of pill liquid to explode and fall short.

After four consecutive failures, Wu Xin put the Nine Snake Furnace there, closed his eyes and meditated.

His divine consciousness could no longer bear it.

In fact, at the last attempt, he would not have failed, but because at the critical moment, Wu Xin's divine sense did not keep up with the speed of his Dan Division, so it caused the ball of Dan liquid to disperse.

Three days later, Wu Xin reopened his eyes, and after examining the Nine Snake Furnace, Wu Xin took a deep breath and spit out the Fallen Heart Flame again.

Half a month later, outside the cave.

Yue Fatty, who was sitting at the entrance of the cave and scanning back and forth, suddenly turned around and looked behind him!

Looking at the whirlpool of spiritual energy generated by too much suction at the entrance of the cave, Yue Fatzi's eyes couldn't help but flash a hint of joy.

The aura is poured out, and the Determined Dan is done!

Wu Xin in the cave, with a smile in his eyes, finally succeeded!

After the aura pouring into the cave slowed down, Wu Xin stretched out his right index finger and flicked it on the stove lid with force!

Bite~

The lid shattered in response!

After refining the Ruiyi Pill once, the Nine Snake Furnace shattered again!
