Mu Chen looked at the man in black with his arms crossed, thought for a moment, and asked, "Have you done any preparations yourself?"

The man in black took out a rusty iron ball and handed it to Mu Chen, saying, "I found this in a Wuzong relic. This person has also failed twice in the promotion. I don't know, he finally advanced. Is it related to this iron ball?"

"Mu Chen, this thing looks familiar!" Ye Shi stepped forward and said.

Mu Chen nodded and said, "It seems so, I seem to have seen it before."

Mu Chen took out a brocade box from the spiritual pagoda. Inside the brocade box was an iron ball that was similar to the iron ball taken out by the man in black.

The iron ball in Mu Chen's hand was obtained by Mu Chen in the Jin family ruins before, and Mu Chen never understood what it was.

As soon as the two iron balls met, they burst into golden light at the same time, and they quickly merged into one, turning into a golden yellow color. Some strange words appeared on the surface of the metal balls.

"What is it!" Ye Shi leaned forward and asked.

Mu Chen said lightly: "It's an inscription that helped Emperor Wu advance to Wu Zong."

"That Su Xindan, the Spirit Sect Formation, and this inscription, are they enough?" Ye Shi asked.

Mu Chen shook his head and said, "I don't know, there should be a chance?"

Ye Shi asked cautiously, "How many chances are there?"

"Twenty percent." Mu Chen thought about it for a while.

When Ye Shi heard Mu Chen's answer, he felt like he was about to faint, "It's only 20%!"

Ye Shichao looked over at the man in black and secretly said: This guy is dead, the pill, the formation, the inscription, and the three formations are all together, there is only a 20% chance, this guy will definitely explode and die.

Mu Chen shook his head and said, "Maybe not yet." Lie Xingtian's situation could almost be called a terminal illness.

Ye Shi frowned and said, "Is there no chance of 20% of these three methods?" He clearly felt the aura of Lie Xingtian, which was very powerful. He was only one step away from breaking through Wuzong.

"Actually, there is a way, maybe you can try it." Mu Chen pondered for a while.

"What?" Ye Shiman asked curiously.

"Lingxin Pill, this kind of medicine pill, can realize the next realm. With this kind of medicine pill, you should be able to grasp it by 30%." Mu Chen said.

"Lingxin Pill, what kind of medicine is this! It's so powerful, the Spirit Sect Formation, the inscription plus the Suxin Pill, is only less than 20%." Ye Shi muttered with wide eyes.

"Good medicine pill." Mu Chen said.

He also recently got Lingyin Xing to know that there is such an eighth-level medicine pill.

Outside of the secret, the place where the alchemists gathered was blown up.

"Lingxin Dan, what exactly does this fellow Mu Chen want to do!"

"Does he want to use the eighth-level Lingxin Pill to help a Martial Emperor break through the Martial Sect? It's too talented and too wasteful." Lingxin Pill is an eighth-level elixir, which is usually used to help Wuzong advance to Martial Sovereign.

"In the hands of Lie Xingtian, what is it that makes Mu Chen so tempted, he actually thinks of using an eighth-level medicinal pill!"

"Is Mu Chen joking, or is he serious!"

"Did he plan to refine the Spiritual Heart Pill? Jinyang Pill, at best, can only be regarded as a kind of medicinal pill that is priced between the seventh and eighth level. The difficulty is much higher than that of Jinyang Pill."

"Who knows, just wait and see, if Mu Chen really wants to refine the Spiritual Heart Pill, then we will be blessed again."

"With Mu Chen's strength, refining the Jinyang Pill is barely enough, and refining the Spiritual Heart Pill is probably not enough."

"Three times before and after Lie Xingtian failed to be promoted to Wu Zong. If we don't predict, there is indeed no chance to be promoted to Wu Zong. If this kid is really promoted to Wu Zong, there will be another peerless murderer in the secret realm."

Bai Chenxing frowned, could it be for... the pill recipe of the Soul Resurrection Pill, if it was for this, then Mu Chen really... left him speechless.

Inside the secret.

Lie Xing Tian glanced at Mu Chen a few times, then bowed his hands respectfully and said, "There's nothing more to do with Mu Chen."

Mu Chen smiled and said, "It's just a business. Whether the Spiritual Pill can be successful or not, I still have to spend time to consider it. The inscription is also. I hope that Lie will give me seven days."

Nine days later, it was the bastards from Zhuang Jin who made an appointment with Mu Chen and Ye Shi to exchange the time for the pill recipe with the spirit pagoda. If the road to Xingtian didn't work, no matter how disgusting he was, he would go there. Will meet Zhuang Jin's gang.

Lie Xing Tian glanced at Mu Chen and said, "Yes."

Ye Shi looked at Mu Chen with a puzzled look, puffed up his cheeks, and said, "Inscriptions take time to consider, I understand why Lingxin Pill takes time to consider, Mu Chen, you are an eighth-level alchemist, don't you? Will you be able to refine Lingxin Pill?"

Mu Chen smiled helplessly, and said, "Although I'm an eighth-level alchemist, I really don't have the slightest confidence in Lingxin Pill."

Ye Shi: "..."

"Why! Lingxin Dan is so difficult to refine!" Ye Shi muttered inexplicably.

"Because Lingxin Pill is also an eighth-level pill." Lie Xingtian said.

"Ah!" Ye Shi covered his mouth and looked at Mu Chen in disbelief. After a while, he lowered his voice and said, "Is it necessary?"

Mu Chen folded his arms and said reluctantly, "No surprise, the success rate is very low."

Lie Xing Tian cultivates the Immortal Killing Sword. This sword technique is unstoppable. There are few rivals at the same level, but there is a fatal weakness. The barrier to advancing to Wu Zong is very thick and difficult to break through.

Lie Xingtian's cultivation all the way went smoothly and smoothly. Lie Xingtian's master originally thought that although Lie Xingtian's promotion to Wuzong was more difficult, it was not too difficult.

The first time Lie Xingtian tried to break through, he didn't pay too much attention to it, so he failed. The second time, Lie Xingtian was fully prepared to make a breakthrough. Unfortunately, he still failed.

The result of three failures is that it has become almost impossible for Lie Xing Tian to break through Wu Zong.

Yin Nitian, the master of Lie Xingtian, also thought about getting spiritual and heart pills for Lie Xingtian. However, there are only a few eighth-level alchemists in Central Continent, and eighth-level pills are so easy to get.

After talking with Lie Xingtian for a while, Mu Chen got into the spiritual pagoda.

The next day, the Dan store opened normally, but there was a black-clothed servant in the store.

After entering the Samsung Martial Sect, Ye Shi's strength growth slowed down. Seeing that Mu Chen went to study medicine pills, Ye Shi picked up the spell that had been put away for a long time.

Ye Shi took out the family formation book and studied it carefully.

After returning to Bai's house, Ye Shi wanted to hand in the formation book, but the Bai family only had Bai Chenxing and Ye Shi, who could open the formation book.

In the medicine store, the books and materials related to the formation can be exchanged for spiritual pills. Recently, many medicines in the medicine store have been exchanged for things related to the formation.

Ye Shi devoted himself to studying the formation in the spiritual tower, and all kinds of formation knowledge came into Ye Shi's mind one after another.

Ye Shi gradually sank into the study of the formation, and there was nothing left in his eyes except the formation.

A burst of blue aura emerged from Ye Shi, and Ta Ling hid behind Ye Shi, flickering with yin and yang eyes, and the yin and yang eyes were full of surprise.

Three days later, Ye Shi suddenly opened his eyes, and his Lingwen eyes glowed with a thick purple-gold light.

"Hey, I'm a four-star Martial Sect." Ye Shi said in surprise.

"Yeah! You've been cultivating for more than three days. There are now about six times the time in the spiritual pagoda, and more than ten times in the secret realm. For such a long time, it's been more than half a year outside, and it's nothing to enter the four-star tower." Ghostly way.

"How did I get into Four Stars? I completely forgot." Ye Shi said with some confusion.

Ta Ling squeaked and smiled, and said, "It's only four stars, and a bunch of Wu Zun outside are waiting to cut you and Mu Chen."

Ye Shi frowned, ignoring Taring's words, and said, "I'm going to use the formation room to simulate the formation."

Ta Ling nodded and said: "Go, run out, hurry to find the spiritual meridian, it has only been a few days, you have used up three spiritual meridians, you are such a prodigal, how good."

Ye Shi said with a dark face, "What nonsense are you talking about, you obviously used it, look at your appearance..."

"What's wrong with my appearance?" Taring asked inexplicably.

"I'm fat, I'm dead!" Ye Shi said in a sullen voice, the spirit tower can't be described as fat or thin, but the tower spirit is to give Ye Shi a fleshy, fat and oily feeling, "You Looking at your appearance, there are so many gourds." The eaves and corners of the Ling Pagoda are covered with all kinds of small jade gourds.

Ta Ling said helplessly: "Go to the formation room, don't you want to simulate the arrangement of the formation? Go!"

Ye Shi snorted coldly and got into the formation room.

Ta Ling looked at Ye Shi's back with a faint gaze. Not long after Ye Shi was reading the book of pills, he seemed to have entered the epiphany of the formation, and Ye Shi's epiphany lasted more than three days at once, which was equivalent to half a year outside.

How many people can have an epiphany for such a long time, Ye Shi probably hasn't realized how much benefit this epiphany has brought him, Ta Ling secretly said.

Fourth day.

Liying Tian stayed in the Pill Shop as usual, and when he saw Ye Shi coming out, he couldn't help but be stunned for a moment, "Master Bai, why did you suddenly leave the customs, Master Mu?"

Ye Shi's eyes lit up, and he said, "Mu Chen is still concocting alchemy. I thought of something that might be useful. Come out and give it a try."

Lie Xing Tian asked curiously, "What?"

"The original level of the Spirit Sect formation was a bit low. I improved it, maybe the effect will be better." Ye Shi said confidently.

Lie Xing Tian smiled and said, "So that's how it is!"

Lie Xingtian listened to Ye Shi's words, and felt a little disapproval in his heart. Although Lie Xingtian didn't think that Ye Shi had the ability to upgrade the formation, he didn't refute anything.

"Would you like to come see me?" Ye Shi turned his head and asked Lier Xingtian.

Lie Xingtian nodded and said, "Okay!" Dan Shop was watched by a towering spirit and a tiger, and ordinary people would not dare to make trouble. Lie Xingtian was just a decoration in the shop.
