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

Sun Yi has never forgotten the time when Wu Muyan activated the Four Symbols Mysterious Spirit Formation to match his own explosive attack power. Although he has been busy with the development of the sect during this period, he has not stopped research in various aspects.

The eight divine souls in his sea of ​​consciousness are not just for show. Only Sun Yi himself knows the power of the Divine Art. The correct way to use the Divine Art is to concentrate the secondary soul on research.

Now, the four divine souls in the sea of ​​consciousness are mainly researching communication technology and improving communication theory. The main purpose is to combine modern scientific knowledge with various knowledge of the world of immortal cultivation. The workload is not small, so he directly arranged four divine souls to carry out the research.

There is also a soul that mainly studies the technology of purifying the residual souls of monsters in the second stage of the Body Tempering Blood Pool.

Sun Yi used the remaining two spiritual souls to mainly study the formation. Since he had the Xuanling Formation Manual in his hand, he would be doing a disservice to this treasure manual if he did not study the formation hard.

Sun Yi's seven secondary souls are all fully engaged in researching various advanced technologies, while the main soul maintains daily training and sect affairs. The main soul and the secondary souls generally do not affect each other. Sun Yi only needs to fuse the eight souls once every once in a while.

As Sun Yi's research on the Xuanling Formation Classic continued to deepen, he discovered that the Five Elements Formation could better complement his Five Elements Power and Five Elements Spirit Sword, helping him to unleash even more powerful power.

So Sun Yi used the sect's resources to create a set of third-level, ninth-grade five-element formation flags and formation plates.

It was not too stressful for Sun Yi to activate the Five Elements Formation alone, but it was very difficult to control the Five Elements Formation, Qingyun Battle Armor and Five Elements Flying Sword at the same time.

Even with Sun Yi's spiritual strength, it would be extremely difficult to simultaneously control five third-grade eighth-grade flying swords, five third-grade ninth-grade formation flags, one third-grade ninth-grade formation plate, one third-grade ninth-grade Qingyun battle armor, and eighteen third-grade ninth-grade sharp blades.

In the middle stage of foundation building, Sun Yi could barely control these spiritual weapons at the same time, but it was a bit difficult to activate them.

Not to mention adding the power of the formation to his other two attacks.

Now that his realm has been elevated to the late stage of foundation building, all aspects have been improved. At the same time, his ability to control so many spiritual weapons has also been improved a bit, but it is still a bit difficult to fully add the power of the formation to the two attacks.

"What if the power of the Five Elements Formation is added to the Five Elements Spirit Sword alone?"

"The Five Elements Formation Flag can be used to activate the Five Elements Formation. What if the Five Elements Formation Flag is replaced with a Five Elements Sword?"

"But how can the Five Elements Spirit Sword replace the Five Elements Formation Flag?"

Thoughts flashed through Sun Yi's mind. There was no way to add the power of the Five Elements Formation to the Five Elements Spirit Sword and the Qingyun Armor at the same time. Sun Yi decided to try a different approach.

After fully recovering the consumed true energy, Sun Yi began to act. As soon as he thought about it, the five elements formation flags appeared around him and the formation plate instantly appeared above his head.

Sun Yi injected his true energy into the array plate, and the five elements array plate above his head suddenly emitted five kinds of light, and mysterious array patterns emerged on the surface.

Sun Yi clasped his hands together, and the five formation flags around him also emitted a kind of light, and the Five Elements Formation was instantly activated.

With Sun Yi's current cultivation level, the formation activated by the third-level, ninth-grade Five Elements Formation Flag is extremely powerful. Sun Yi feels that he can easily kill an early-stage Jindan cultivator.

But this is obviously not what Sun Yi wants. With his current strength, he doesn't need to rely on formations to kill an early Jindan cultivator.

After the formation was activated, five sword lights flashed through Sun Yi's body, and the Five Elements Spirit Sword flew out. Sun Yi hurriedly controlled the Five Elements Spirit Sword and wanted to integrate it into the Five Elements Formation.

The first integration failed, the second integration failed...

After the failure, Sun Yi did not give up, but continued to try and analyze the reasons for his failure. The Five Elements Formation and the Five Elements Spirit Sword belong to the same five elements, so it should be easier to integrate them.

After failing again and again, Sun Yi analyzed the reasons for the failure again and again, and then thought about solutions. Time passed unknowingly.

After failing hundreds of times, Sun Yi's true energy was exhausted again and again. He had to rely on high-quality spirit stones to restore his true energy, which consumed a lot of energy.

As the saying goes, failure is the mother of success. After hundreds of failures, Sun Yi finally came up with a solution in his mind.

So he decided to refine the Five Elements Spirit Sword again. He found Ergouzi and asked him to help him prepare the precious materials for re-refining the Five Elements Spirit Sword. Then he started tinkering with it alone in the training room.

Today, Qingyun Sect is very wealthy and has stockpiled a lot of various precious materials. It is too easy for Sun Yi to refine a set of five-element spirit swords.

Moreover, as his cultivation level improves, he will be able to refine a third-level, ninth-grade spiritual weapon by himself.

At this time, Sun Yi was sitting cross-legged in the training room, with a large ball of purple spiritual fire floating in front of him, and the terrifying high temperature filled the entire training room.

Five spirit swords were suspended in the flames, and each spirit sword exuded the aura that only a third-level, ninth-grade spirit sword could possess. At this time, Sun Yi had integrated his huge soul and was carving mysterious weapon patterns and formation patterns on the five spirit swords.

And below the five spirit swords, there is a spirit plate quietly floating in the flames and being tempered.

Not long after, Sun Yi suddenly merged his five drops of blood into the Five Elements Spirit Sword, and only then did he successfully refine the Five Elements Spirit Sword.

After retracting the Purple Extreme Wild Flame, Sun Yi looked at the brand new Five Elements Spirit Sword in front of him. Feeling the terrifying sword energy fluctuations emanating from the Five Elements Spirit Sword at this moment, Sun Yi showed a relieved expression on his face.

With a wave of his hand, the Five Elements Spirit Sword and Spirit Plate were directly taken into his body and began to be refined.

It was unknown how long it had been before Sun Yi opened his eyes again. Two rays of brilliance flashed from his eyes. With a thought, five sword lights burst out from his body. They were the newly refined Five Elements Spirit Swords. Each sword emitted the fluctuations that only a third-grade, ninth-grade spiritual weapon could possess.

Powerful sword energy waves emanated, and as Sun Yi controlled it with his mind, the five spirit swords shuttled around Sun Yi's body, transforming into sharp sword lights, which looked extremely powerful.

"The five elements are united into one!"

Under Sun Yi's control, the five spiritual swords suddenly merged into one, turning into a colorful giant sword that appeared above Sun Yi's head. Powerful sword energy fluctuations emanated from it, which could definitely crush ordinary mid-stage Jindan cultivators. It was much more powerful than the colorful giant sword formed by the previous third-level eighth-grade flying sword merging into one.

Sun Yi nodded slightly. Sure enough, after the equipment was upgraded, the power it could unleash would be even stronger. However, this was only the previous state of the Five Elements Spirit Sword.

Sun Yi's mind moved, and the colorful giant sword instantly turned into five spiritual swords again, and then a colorful array plate appeared above Sun Yi's head.

Sun Yi activated the Five Elements Kung Fu, and injected a vast amount of true energy into the formation plate. The colorful formation plate above his head shone brightly, and complex formation patterns emerged.

Sun Yi clasped his hands together, and complex patterns appeared on the surfaces of the five spiritual swords around him, instantly establishing a mysterious connection with the spiritual disk above his head. As Sun Yi exerted all his strength, a five-element sword formation was formed in an instant.

At the moment the Five Elements Sword Formation was formed, Sun Yi clearly felt that the sword energy fluctuations emitted by the five spirit swords suddenly increased fivefold. Although the consumption of true energy also increased, Sun Yi understood that the Five Elements Spirit Swords had become different and were blessed by the power of the Five Elements Formation.
