Cao Chuan naturally knew what Xue Menghe was worried about, and it was enough to see it at a glance.

It is precisely because of this that Cao Chuan's face showed a little smile.

He got up and walked to Jiangjinjiu and Xue Meng, and said to the two: "Actually, before coming to Zhongzhou, I met the dog leg around Liu Chen, and successfully found some news about Liu Chen from him, I think these news are very important to us. ”

Then Cao Chuan told Jiang Jinjiu and Xue Meng all the news he had found from Wang Sansi, the most important of which was undoubtedly that Liu Chen's second breakthrough in the realm of the cave ruins was not too sure, and it could even be said that Liu Chen's second breakthrough was likely to fail again.

And once Liu Chen failed to attack the Cave Ruins Realm for the second time, not only would the clan forces that had seen him be disappointed, but even the Zhongzhou Tianling Academy's own family, which had chosen to deliberately give up Jiang Jinjiu in order to keep Liu Chen, would also choose to cut the relationship with Liu Chen as quickly as possible, and at the same time win over the relationship with Jiang Jinjiu.

After all, winning over the general can also show favor to Xue Meng.

You must know that Xue Meng not only has his own cultivation talent good enough, but the Xue family and Luoyang Villa behind him are the top forces in Zhongzhou.

For the Heavenly Spirit Academy family, who didn't want to give up their status in Zhongzhou, this was obviously the most correct.

Even if they didn't know what Jiang Jinjiu and Xue Meng thought in their hearts.

But at least for Jiang Jinjiu and Xue Meng, the pressure that has been exerted on them during this period of time is finally a little less.

It's just that they haven't completely relaxed.

Because all of this is just a possibility, it proves that Liu Chen may still succeed in breaking through to the Cave Ruins Realm.

So Cao Chuan has already made full preparations in order to deal with this situation.

After trying to refine the eight-rank pill, Cao Chuan's attainments in alchemy have surpassed most alchemists, and he can even be called the most powerful alchemist on the bright side, once his identity is known, even if Liu Chen really breaks through to the cave ruin realm, he will not dare to provoke him easily.

A seventh-grade alchemist is enough to make Zhongzhou boil, let alone an eighth-grade alchemist who hasn't even reached the age of eighteen.

But Cao Chuan is preparing to use his current alchemy skills to refine an eight-pin pill called "Eight Grades Open Heaven Tongxu Pill".

The Eight Rank Open Heaven Tongxu Pill, a kind of pill that can allow Yuan Shen Realm monks who take this pill to increase the success rate of breaking through to the Cave Ruins Realm, can increase by at least forty percent.

The higher the grade, the higher the increased success rate.

But it is not so simple to refine the eight-rank pill, even Cao Chuan, who has already refined the eight-rank pill, can only pray that his luck is good enough.

As for the various materials needed to refine the pill, there is no need to worry, when he was in the secret realm before, Cao Chuan took Wen Jinghao and Yu Qinglan to scavenge all the valuable things in it as quickly as possible, even if half of it was distributed to the Jin family and the Ice and Snow Heavenly Sect, the remaining materials in the storage bag were enough for him to refine the eight-grade pill as he wanted.

It can be said that the current situation is that everything is ready, only the east wind is owed.

Cao Chuan immediately asked Xue Meng for a quiet place to refine the Eight-Rank Open Heaven Tongxu Pill, but what he told Xue Meng was only about refining the pill, and he did not elaborate on what pill he wanted to refine.

And Cao Chuan plans to refine multiple pills, one of which will be handed over to Xue Meng to try to break through the realm.

In this way, even if Liu Chen successfully broke through to the Cave Ruins Realm, then with the help of Xue Meng, who also broke through to the Cave Ruins Realm, the development of things would still be as stable as now, and Cao Chuan and Jiang Jinjiu would be given more time to try to cultivate and progress.

"Besides, don't you still have you to protect me?"

After being taken by Xue Meng to a more remote but absolutely quiet courtyard, when Jiang Jinjiu and Xue Meng left one after another, Cao Chuan turned his back to Yu Qinglan and said with a chuckle: "But it's not that time yet, I still want to solve this matter with my own strength." ”

After speaking, Cao Chuan took out more than a dozen materials from the storage bag for refining the Eight-Rank Open Heaven Tongxu Dan.

These materials were all scavenged from the secret realm, so he didn't feel distressed.

When he began to refine the elixir, he used the most radical method to try to refine it.

But soon.

Due to the radical technique, Cao Chuan, who failed to grasp the temperature of the flame for a while, resulting in the burning of the materials, immediately began his second attempt at refining.

This time, Cao Chuan chose a more secure refining method.

Facts have also proved that during alchemy, in addition to being disturbed by the outside world, the alchemist must not be affected by the changes in his own inner emotions.

Anyone in between who is influenced by one of them will have a high probability of alchemy failing, just like Cao Chuan's brief first attempt.

But the ability to refine the Eight-Rank Pill before was not only because the Eight-Rank Pill refined at that time was one of the easiest Eight-Rank Pills to refine, but also because there was an element of luck in it.

Now in the case that his luck is not outrageous, Cao Chuan can be said to have tried and failed once.

It seems that in the case of the Yuan Shen Realm, it is impossible to refine the eight-rank pill.

Even though Cao Chuan had already used the power of all the fires in the Chaos Divine Tree.

More and more attempts.

Cao Chuan's mood couldn't help but get worse and worse.

Feeling more and more irritable, he even wanted to give up this time the elixir refining.

But Mu Qingqiu's voice, which suddenly sounded in the sea of knowledge, made Cao Chuan, who had a good heart, quickly wake up from his loss.

"Without the help of the Eight Rank Open Heaven Tongxu Pill, if that senior sister of yours wants to break through to the cave ruin realm, she will definitely encounter the same predicament as that Liu Chen, but if that Liu Chen's second attempt succeeds, and your senior sister fails, what do you think you and them will encounter next?"

"Compared to the difficulties you suffered and the failures you experienced while refining the pill, which kind of failure do you think is more unacceptable?"

Cao Chuan did not answer Mu Qingqiu's question, but used his actions to prove that he was no longer affected by his mentality.

And after that, although he still failed several times in the process of trying to refine.

However, Cao Chuan, who was more and more comfortable with extremely complex refining techniques, gradually began to see the hope of successful refining.

So in a good mood, Cao Chuan, who was already the thirteenth attempt to refin, finally made no mistake in the process of refining the spiritual liquid for the first time, and also successfully transitioned the refining to the final step of condensing into a pill.

As long as the pill can be successfully condensed and formed, the eight-rank Kaitiantong Xuan Dan can be regarded as a successful refining.

In this regard, Cao Chuan's spirit was highly concentrated, and Wen Jinghao and Yu Qinglan acted as temporary guards in the courtyard to prevent Cao Chuan from being disturbed by the outside world.

Mu Qingqiu didn't ask Cao Chuan or make other noises, but honestly stayed in the depths of the sea of knowledge, quietly observing the pills that had begun to gradually take shape in the Dan furnace.

The speed of the Eight Pins Pill is extremely slow.

Even if Cao Chuan used his full strength to use the thirty-six death points in his body to absorb and refine the spiritual power of heaven and earth, and to provide a steady stream of spiritual power for the Dan furnace, it would only make the speed of the pill into a pill a little faster.

But Cao Chuan knew that the more times like this, the more he couldn't be in a hurry.

So he calmed down and continued to let the pill gradually become a pill under the wrapping of spiritual power.

In this way, Cao Chuan sat in front of the Dan furnace for three days and three nights.

The Eight Grades Open Heaven Tongxu Dan was finally refined for three days and three nights.

And with the help of the alchemy annotation, Cao Chuan also refined the eighth-grade Open Heaven Tongxu Pill this time, and there were as many as six in one furnace, even if he gave two to his own senior brothers and sisters, he would still have three left after taking one more.

And the remaining three Eight Rank Open Heaven Tongxu Pills were enough for Cao Chuan to gain a firm foothold in Zhongzhou, even if Liu Chen really broke through to the Cave Ruins Realm, he would definitely not have the courage to do it in front of the Eight Rank Pills.

Cao Chuan was naturally very satisfied with this, and immediately took the elixir to restore spiritual power, and then went to meet his senior brother and sister with the eight-grade Kaitiantong Ruin Pill that was carefully placed in a porcelain bottle.

This plan for Liu Chen officially began at this time.
