To be the best leader, you must also be the strongest leader!

Sun Yi knew very well that Qingyun Sect's future goal was to destroy Tiansheng Palace. With Qingyun Sect's current development speed and future plans, it would only take fifty years at most to destroy Tiansheng Palace.

However, Sun Yi will not forget that behind the Tiansheng Palace is the unfathomable powerful Red Dragon Clan. Once the Tiansheng Palace is destroyed by the Qingyun Sect, the Qingyun Sect will be greeted with crazy revenge from the Red Dragon Clan.

Even if the Qingyun Sect could destroy the Tiansheng Palace, it would have no chance of winning against the Chijiao Clan.

Once targeted by the Red Dragon Clan, not only the Qingyun Sect, but even the entire Tianyuan Continent will have no way out.

So Sun Yi has been thinking about how to deal with it.

Before, Sun Yi had three ideas in his mind to deal with future crises. The first way was to find the human race outside the Tianyuan Continent and seek help from external forces.

However, this idea did not make any progress at all. Sun Yi arranged for people to check all the current classics of the sect, but they could not find any news about the human race outside.

It was as if the Tianyuan Continent was the only place with human beings, and even the imprisoned sea snakes had no idea about the rest of the human race.

Although no news of any external human race has been found for the time being, Sun Yi still holds a glimmer of hope in his heart. He firmly believes that there must be other human races outside the Tianyuan Continent. This conclusion can be drawn from the content after the Xuanling Formation Classic was unsealed.

But where are those humans? How can we contact them? These are all questions.

Previously, Sun Yi had considered arranging experts to cross the forbidden areas such as the Endless Sea, the Endless Ice Field, and the Forest of Ten Thousand Demons to search for the human race outside. However, after learning that the demon race had a way to locate the Nascent Soul cultivators who entered the Endless Sea, Sun Yi temporarily gave up this plan. This road was not feasible.

However, there is currently a way to obtain information about the human race outside. The soul fragment of Yao Qianli captured by Su Motang is still imprisoned. If this soul fragment can be searched, perhaps some information can be obtained.

However, the level of Yao Qianli's soul fragment was too high. Even Su Motang, whose soul had reached the great perfection realm of the Nascent Soul Stage, had no way to search its soul. For the time being, he could only keep it imprisoned and look for an opportunity later.

Sun Yi's second response was to find a place to build a secret shelter in the Tianyuan Continent. After destroying the Tiansheng Palace, if he was unable to deal with the Red Dragon Clan, he would find a secluded place to hide and develop, and then seek an opportunity to break the deadlock.

The Tianyuan Continent seems very big, but it is just an island. How easy is it to find a place here that will not be discovered by the Red Dragon Clan?

Sun Yi didn't know what abilities the cultivators in the Spirit Transformation Realm had. The Red Dragon Clan was a super clan with countless means, so they might be found out soon.

This method is also very unsafe, and the last method is to rely on the formation. While destroying the Tiansheng Palace, set up a formation that can withstand the attacks of the Red Dragon Clan.

Before the seal behind the Xuanling Formation was broken, Sun Yi felt that this was the most unreliable method, because the Qingyun Sect could only set up a fourth-level formation at most.

Not to mention stopping a fifth-order monster, even stopping a fourth-order monster is difficult.

Even if a fifth-level formation could be set up, it would be impossible to stop the attacks of the Red Dragon Clan.

However, ever since he saw the Hundred Treasures Killing Formation recorded at the end of the Xuanling Formation Classic, Sun Yi had a vague idea in his mind.

This set of Hundred Treasures Killing Formation is a fifth-level formation that combines offense and defense, with a fifth-level spiritual weapon as the main component and the remaining ninety-nine fourth-level spiritual weapons as auxiliary components.

The Hundred Treasures Killing Formation can unleash the attack power of an early stage Spirit Transformation cultivator.

This Hundred Treasures Killing Formation is difficult to set up and requires a lot of resources. It seems that the cost-effectiveness is not high, but what Sun Yi considers is that the Hundred Treasures Killing Formation can bring out the combat effectiveness of a cultivator in the early stage of the Spirit Transformation Realm.

So if Qingyun Sect could change the Hundred Treasures Killing Formation into the Thousand Treasures Killing Formation, could it unleash the combat power of a cultivator in the middle stage of the Spirit Transformation Realm?

If it is changed to the Wanbao Killing Formation, will this formation have the power to protect Qingyun Sect and be able to withstand the attacks of the Red Dragon Clan?

Although the idea of ​​transforming the fifth-level formation was a bit crazy, Sun Yi knew that this might be the path that Qingyun Sect must take next.

For this purpose, he also specifically requested the R&D department to set up a research and development project team for the Wanbao Killing Array. Sun Yi personally led this project team, and Wu Muyan, Elder Ye Luo and all the elites of the Array Hall joined.

At the same time, Sun Yi also invested a lot of money in this project and formulated various high-value reward policies. Those reward policies alone are enough to make people jealous.

Not only that, Sun Yi also asked Wang Yang and Wu Muyan from the Formation Hall to combine the Xuanling Formation Classic and lead people to re-formulate the teaching materials for the formation subject, update the teaching materials as quickly as possible, and increase investment in the formation subject.

These things had been arranged before leaving Qingyun Sect, so Sun Yi was now fully devoted to the study of the Xuanling Formation Classic.

Time passed by unknowingly, and the flying boat that Sun Yi was riding was hovering above the Qingyun Square of the Immortal City. Sun Yi walked out of the flying boat, and Li Yunfei and others immediately came to greet him.

"Welcome, Master!" Li Yunfei and others bowed respectfully to Sun Yi.

"Let's go, tell me about the specific changes in Xiancheng."

"Okay." Li Yunfei nodded, and followed Sun Yi towards the main hall.

"Recently, the development of Xiancheng has entered a period of explosive growth due to the opening of Qingyun Bank. According to our statistical analysis, the overall strength of Xiancheng has more than doubled since the opening of Qingyun Bank."

"Most of the resources have been supplied to the Demon-Slaying City. The strength of the Immortal City has been greatly improved. This result is very good." Sun Yi nodded with satisfaction.

"Although most of the resources are supplied to Demon Slaying City, there are a large number of Qi Refining cultivators in Immortal City. After applying for consumer loans, these cultivators have enough Qingyun coins and are actively purchasing cultivation resources. Their realm is improving very quickly."

Sun Yi nodded. He knew very well that as long as a Qi Refining cultivator had top-notch skills and good enough and sufficient cultivation resources, it would not be difficult to improve his realm.

"But there are also some problems." Li Yunfei suddenly changed the subject.

"What problem did you encounter?" Sun Yi looked at Li Yunfei.

Li Yunfei sighed, "Because the realm is improving so quickly, many Qi Refining Great Perfection cultivators have attempted breakthroughs in recent days. Despite the assistance of our sect's Foundation Establishment Pills, many Qi Refining Great Perfection cultivators still failed to break through, and most of them died because of this failure."

"Master, should we fully disclose the Three-in-One now?" Li Yunfei looked at Sun Yi. The news of various breakthroughs and deaths he had received recently made him feel very heavy. The Three-in-One of Qingyun Sect has not been made public yet, and this is also one of the core secrets of Qingyun Sect.
