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

However, this detoxification pill cannot be maintained forever. One needs to be taken every once in a while, and it is very precious.

"Elder Wu, you are responsible for setting up the formation, and the rest of you will deal with the fire spirits here." After Sun Yi finished speaking, he flew towards the huge spiritual peak.

The people from the Formation Hall, led by Wu Muyan and others, began to set up the formations separately.

Just as Sun Yi and his companions approached the huge sacred mountain, a strange cry emanated from the mountain. Then, firebirds flew out of the mountain and rushed towards Sun Yi and his companions.

These firebirds are made entirely of flames. The smallest firebird has a wingspan of about one foot, and its aura is almost as strong as that of an early Jindan cultivator.

The largest firebird had a wingspan of about ten feet, and it exuded an aura similar to that of a powerful cultivator in the Spirit Transformation Stage.

This kind of firebird is a spirit of fire, not a demon. It has no intelligence, but only a very strong sense of territory. Once someone approaches their territory, they will be attacked.

Seeing the dense swarms of firebirds rushing towards this side, Sun Yi summoned the Five Elements Armor without hesitation. The sixteen winged swords, five Five Elements Spirit Swords and the Five Elements Rings turned into streams of light and shot towards the flying firebirds.

bang bang bang...

One firebird after another exploded in the air, like fireworks formed by flames. Those ordinary firebirds could not withstand Sun Yi's attack at all, and turned into flames and dissipated in the air.

However, as long as the firebirds that are comparable to the Nascent Soul Stage and the God Transformation Stage are not torn apart by a single blow, they can quickly recover from their injuries by absorbing the surrounding fire power.

It seems as if they have immortal bodies, and these firebirds can also control fire poison to launch attacks. They are extremely powerful and difficult to deal with.

No cultivator in the late stage of the Jindan realm dared to enter the territory of this group of firebirds.

It’s a pity that the fate of these firebirds was already determined when Sun Yi and his team arrived.

The Human Emperor Flag appeared above Sun Yi's head, and a black vortex appeared on the Human Emperor Flag. The soul of the extinguished firebird was quickly swallowed by the black vortex.

Although the souls of these firebirds are very weak, unlike the demon souls, they can still be used as raw materials for the Heavenly Soul Liquid, so Sun Yi will certainly not waste them.

Sun Yi took action, and Elder Huo Ling, Elder Zhang Ye and others also took action. They all displayed extremely powerful fighting ability and engaged in a fierce confrontation with this group of firebirds.

This group of firebirds can be said to be the overlords of this mountain range. The number of firebirds comparable to the God Transformation Stage alone reaches dozens, and the rest are in the tens of thousands.

In such an environment, these firebirds have strong recovery abilities and can also control fire poison, making them very difficult to deal with.

It’s a pity that he met the top masters from Qingyun Sect.

Soon after, all these firebirds were cleared out by Sun Yi and his men. The souls of the firebirds were completely devoured by the Human Emperor Flag, and Sun Yi's huge spiritual consciousness spread out and covered all directions.

"Let's also clear out some of the fire spirits nearby."

Then Sun Yi led everyone to clear out all the fire spirits nearby to make sure that there were no more fire spirits nearby.

Soon after, a huge formation rose up, and a transparent barrier enveloped the entire sky. The area within a radius of ten thousand miles was within this barrier.

After the formation was set up, everyone began to clean up the fire poison in the formation, and at the same time, they split up to start building the R&D department. Everyone was busy.

For the mortal world, building a huge R&D department definitely takes a lot of time, but for powerful cultivators it is easy.

In just three days, a huge R&D department was built.

This huge R&D department is shrouded in a barrier. The fire poison inside the barrier has been completely purified and the temperature has been controlled. Even a cultivator in the Foundation Establishment stage can stay in such an environment.

This R&D department is divided into different parts, and a teleportation array directly connecting to the War City and Longyan City has been built, making entry and exit very convenient.

The Equipment Refining Hall, Formation Hall, Puppet Hall, Alchemy Hall, and Talisman Hall began to arrange a large number of personnel to move in, and various equipment were placed in the new R&D department.

With the joint efforts of everyone, the new R&D department was formed in less than ten days.

At this time, Sun Yi, the hall masters, and the elite weapon refiners of the R&D department were all suspended in the air, looking at the brand new R&D department below, with expressions of satisfaction on their faces.

"This place is really good, the power of fire is endless." Elder Fire Spirit nodded with satisfaction.

Sun Yi was also very satisfied with this place. He quickly began to make arrangements: "Here in the Weapon Refining Hall, we will focus on developing the latest Fire Gathering Array. One of my soul fragments will work with you on this research. This time, we must use the best technology and the best materials."

Elder Huo Ling nodded. "Alright, with the latest technology, our current material reserves, the current environment, and the assistance of Tianji No. 2, we will definitely be able to develop the best fire gathering array in the shortest possible time."

"Okay, let's organize a team and start research and development now."

Sun Yi turned his gaze towards the Alchemy Hall. "Elder Danfa, Elder Danfeng, Elder Danxin, and Elder Gu Yong, you are our sect's top alchemists. Immediately organize personnel to conduct in-depth research on the Heavenly Soul Liquid. By combining it with the new alchemy teaching materials, you should be able to develop a new spiritual liquid that increases the absorption rate of the Heavenly Soul Liquid."

"We will immediately organize people to start research." Elder Danfa responded immediately.

"I won't need to use my soul to participate in your research, but the computing power of Tianji No. 2 will be fully open to you."

"Thank you for your support, Master." Elder Danfa bowed to Sun Yi.

Sun Yi nodded, then turned his gaze towards the Formation Hall: "Elder Wu, this Soul-Replenishing Formation is very valuable for research. Let's study it together. Based on this third-order Soul-Replenishing Formation, we should strive to create a similar high-order Soul-Replenishing Formation as soon as possible to speed up everyone's spirit cultivation."

Wu Muyan nodded: "Okay, the effect of this soul-replenishing formation is indeed very interesting. If it can be upgraded to a high-level soul-replenishing formation, it will be very useful."

Sun Yi turned his gaze towards the Weapon Refining Hall, and finally landed on Gu Qingcheng. He then arranged, "Gu Qingcheng, you will lead a team alone. I plan to develop two new products."

"One of the spiritual tools has an effect similar to a cultivation space, but it's actually an aid in spiritual cultivation. Currently, there's only a rough outline. I'll compile a research and development plan for you, and you'll recruit personnel and organize a research and development team."

"In addition, I also plan to develop a spiritual tool that can help comprehend the skills. I already have a detailed R&D plan, but if I want to speed up the development, I also need to organize a R&D team."

"You will be in charge of both research and development projects. I will arrange for the soul fragments to participate in the research."

Sun Yi looked at Gu Qingcheng and handed the research and development of the two projects to Gu Qingcheng. Now Gu Qingcheng is one of the top refiners in the Refining Hall and has extremely outstanding research and development capabilities.
