Qi refining is still mortal, and only building a foundation is the beginning of transcendence.

This is a clear division of the realms marked in the cultivation classics, after all, strictly speaking, there are actually only four realms of cultivation, refining qi and building the foundation, corresponding to the fourth order of the Jindan period, and corresponding to the immortal level of the saint rank.

As a stage of accumulating and refining energy, the Qi refining period actually does not have too obvious boundaries, as long as the cultivator has made certain progress in cultivating energy, it can be regarded as a successful Qi refining, and it is more of a natural transition of the cultivator's own energy accumulation...... And for orthodox cultivators, foundation building is an important milestone.

Building a foundation means that the cultivator can convert the energy accumulated in the body into true yuan power, which is a complete transformation of the cultivator from the outside in. Whether it is the use of spells, supernatural powers, magic weapons, rune analysis, or energy running speed, it is ten times and a hundred times that of the Qi refining level, which can be regarded as entering the hall and officially embarking on the road of cultivation.

The importance of the foundation building stage is self-evident, it not only requires the quality of the cultivator himself, but also a comprehensive test of his talent, state of mind, perseverance, and depth of understanding of the path of cultivation, and every link may become the key to the success of foundation building.

So far, only Yang Yun and Qi Teng have successfully built a foundation in the Zhongzhou team, which in itself can reflect the difficulty of building a foundation. And even Cheng Xiao, who has been practicing martial arts since he was a child, does not dare to say lightly that he will definitely be able to complete this important transformation before the next mission world begins.

"Use the formation to help me build a foundation?"

Listening to Chu Xuan's words, Zheng Zha's eyes suddenly lit up: "It's a big help, Chu Xuan, it will save me a lot of things now." ”

As the core figure of the Zhongzhou team, Zheng Zha's efforts and achievements in cultivation are obvious, but the challenges and pressures he faces are also huge. On the one hand, he needs to invest a lot of time and energy to optimize his genes and shape and perfect his perfect body; On the other hand, Zheng Zha also has to spend time cultivating the Seven Strikes of Purple Thunder and developing and improving his own self-created skills.

The shaping of a perfect body is a long and difficult process that requires constant tempering and adjustment; The complexity of the Purple Thunder Seven Strikes is not trivial, and in order to truly master and use it freely, it requires deep understanding and continuous practice; Whether it is "destruction", "falling stars" or "heavenly thunder breaking the world", it requires Zheng Zha's deep understanding of the essence of martial arts......

With the need to invest energy in many aspects, even if Zheng Zha can be called a martial arts genius, it is impossible for him to achieve perfection in all aspects. So when he heard that Chu Xuan could help him save time in building a foundation in this way, Zheng Zha readily agreed.

“…… Wait, Chu Xuan, you said that you want to use this formation to help Zheng Zhe build a foundation, but how to do it? ”

It's just that compared with Zheng Zha's optimism, Yang Yun instantly remembered the situation in the original book when Chu Xuan used the magic cannon to help Zheng Zha's foundation, and couldn't help but have a long heart: "Although there are also ways to forcibly build a foundation by external forces in the cultivation classics, the core of this formation should be the word 'town', which sounds very professional and wrong." Shouldn't it be better to use a formation like the Spirit Gathering Array? ”

"No problem, the essence of building a foundation with external forces is an extremely large amount of energy infusion, which is enough to withstand the corresponding energy response in terms of Zheng Zhe's physical fitness."

Chu Xuan waved his hand and said indifferently: "Zheng Zha's accumulation is abundant, so the Spirit Gathering Array in the conventional sense will not have much effect on him, and he needs to use a relatively powerful formation to build a foundation, so that he can transform the huge energy in his body into true yuan power in one step...... Considering the role of the formation itself, it is obvious that this formation is the most suitable choice. ”

- If I'm not mistaken, Chu Xuan seems to have just said the word "might", right? This simple and crude method ...... Could it be that Zheng Zha felt that he was thick and durable, so he treated him as a guinea pig?

There was a hint of confusion in Yang Yun's expression, he had originally planned to propose to Chu Xuan to return to the curse plane and ask the moment if there was a safer way to use external force to build a foundation. However, now that I look at it, this guy is clearly deliberate, he just dug a big hole for Zheng Zhe......

When Yang Yun looked sideways at Qi Teng for a while, he noticed that the other party also had a look of wanting to speak and stopping. Obviously, Qi Teng was an orthodox cultivator, and he had similar confusion and concerns in his heart, but because it was Chu Xuan who made this suggestion, the current atmosphere was harmonious, and he couldn't say it at all.

"In other words, this method is actually exclusive to Zheng Zha, and it is not suitable for us?"

Yang Yun and Qi Tengyi both smelled the smell of danger, but the others were all attracted by Chu Xuan's foundation building idea and did not notice the waves hidden under the water. Even Cheng Xiao, who had just exchanged a bunch of materials from the main god, heard Chu Xuan's explanation, and said with some disappointment: "I thought I could also save the effort of building the foundation in this way, so that I could use the new weapon earlier, and I also saved a lot of effort...... It didn't work out. ”

"For now, this method of building a foundation is only suitable for Zheng Zhe alone."

Chu Xuan gently pushed the glasses on the bridge of his nose, and somehow, a cold light unexpectedly flashed on the lenses of his glasses, which made Yang Yun next to him tremble: "I need a lot of research data to verify the corresponding conjecture, but if this method of building a foundation is successful, then I will consider promoting it in the future......"

- No, Chu Xuan, are you a little too extreme?

Yang Yun looked at Chu Xuan upside down black and white in a daze, and didn't know what to say for a while. The most unbearable thing is that Zheng Zha, who heard that he could save the foundation building effort, didn't care about Chu Xuan's specific words at all, but was completely attracted by the bright prospects depicted by the other party, as if Cheng Xiao before, and even nodded in agreement: "That's right, my body is indeed very strong, and it is appropriate to use a strong formation to build the foundation...... How do you say that? Fire forges real gold. ”

- It's really fire forging real gold, but I don't know if you will regret it......

Hearing that Zheng Zha's words were full of expectations for the future and confidence in his own abilities, Yang Yun and Qi Tengyi glanced at each other again, and wisely chose to be silent.

The next moment, Qi Tengyi contacted the main god without saying a word under a B-level side plot supported by Zhao Yingkong, anyway, for him who had no special requirements, it was okay to exchange this set of Five Spirit Town Pulse Maps; And Yang Yun floated to Zheng Zha, who began to enjoy the good life after his successful foundation, patted him on the shoulder and said, "Zheng Zha......"

"Huh? What's wrong? ”

"Your two A-level side plots this time, you have to think carefully about what to exchange." (End of chapter)
