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

"Okay, Xiaoqi, I still have some important things to do. Just let the eldest brother play with you. I will come to see you after I am done." Sun Yi rubbed Xiaoqi's head.

"Master, you just came back and are you leaving again?" Xiao Qi looked at Sun Yi with some disappointment.

"Master will not leave the sect for the time being. I will come to see you soon. Be good and obedient."

"Xiao Qi knows that Master is the head of the sect and has many things to do. Xiao Qi will definitely obey."

Sun Yi smiled and nodded again, then said goodbye to Su Motang and Zeng Niu and went directly to the R&D department.

Today's R&D department is much larger than before, and the number of staff in the entire R&D department has increased a bit, with the new members being outstanding research talents who graduated from the Chuangong Hall.

Although these disciples are all newcomers, their research talents are not weak at all.

Sun Yi swept his spiritual sense and found Gu Qingcheng and the others directly, so he came to their location as soon as possible.

At this moment, a group of people gathered together, looking at Zhang's smelter.

At this moment, a ball of true fire was floating in front of Zhang Ye, which was wrapped with a bunch of refining materials. Under the calcination of the true fire, the impurities in these materials were being continuously extracted.

Sun Yi also came over and found that Zhang Ye's method of refining materials was very different from the method they used.

The real fire in front of him seemed calm all night, but it was spinning rapidly inside. Flame vortexes were formed in small areas, and the materials were refined faster in the flame vortexes.

"What kind of refining method is this?" Sun Yi asked curiously.

"Greetings, Master!" The others hurriedly greeted Sun Yi. Sun Yi smiled and nodded, his attention continuing to focus on the flames in front of Zhang Ye.

"This is the Nine-Turn Mysterious Fire Tempering Method. Using this secret technique to control the flame can greatly improve the efficiency of quenching materials, and the quality of the refined materials will also be better." Zhang Ye replied.

"So that's how it is. This should be the Xuanhuo Sect's secret weapon refining technique, right?" Sun Yi looked at Zhang Ye.

Zhang Ye nodded: "This is one of the three great tempering secrets of Xuanhuo Sect."

"Can it be spread outside?" Sun Yi asked directly, not being polite at all.

"This is the secret technique I obtained before I entered the Xuanhuo Sect, so I can pass it on to others. If you want to learn it, I will teach you later." Zhang Ye didn't mind passing this secret technique on to the people of the Qingyun Sect.

"That's great. Why don't you just make a copy of everything you can teach us so we can study it carefully. We're all family after all, so we need to study more in the future."

Sun Yicai didn't have any prejudice. In the world of immortal cultivation, it was taboo to inquire about other people's cultivation techniques, let alone ask for them directly. However, Sun Yi didn't care about that. It would be a waste if these good things were not promoted in the R&D and production departments.

"Okay." Zhang Ye did not refuse.

He now knows more and more about Qingyun Sect, and knows that Qingyun Sect has mastered many extremely powerful technologies, such as the Five-Gate Technology, the Demon Refining Tower, and the Body Tempering Blood Pool. These will not be kept secret from him. He is also willing to give the secret weapon refining techniques he has mastered to Qingyun Sect to help Qingyun Sect develop.

"Are you refining the latest body-tempering blood pool?" Sun Yi couldn't help but look at the various materials in the flames with curiosity.

Palace Master Yan nodded and replied, "Yes, this is the second-stage Body Tempering Blood Pool we recently developed. As Elder Zhang happens to be a fourth-rank weapon refiner, we decided to ask Elder Zhang to refine one for us to test and see if our design is feasible."

"Don't worry, we have already discussed it so many times, there will definitely be no problem." Gu Qingcheng looked determined.

"If the second-stage body-tempering blood pool we refine this time can really succeed, it would be perfect." Wantong's face was also full of excitement. This second-stage body-tempering blood pool also had the contribution of their Talisman Hall. If it could really succeed, their Talisman Hall would also have made a contribution.

Next, Sun Yi and the others carefully observed Zhang Ye refining the equipment and carefully learned Zhang Ye's refining techniques.

Zhang Ye is indeed a fourth-rank weapon refiner. Even though his consciousness was injured and his spiritual fire was taken away, Zhang Ye still displayed the power of a fourth-rank weapon refiner.

His control over true fire far surpassed Sun Yi's. Previously, Sun Yi thought that his control over fire was already very advanced.

But after seeing Zhang Ye's control over the flame at this time, Sun Yi realized that he was still far behind. If Sun Yi's own control over the flame was level three, then Zhang Ye's control over the flame was level five.

Sun Yi saw the gap between himself and Zhang Ye, and carefully studied some of Zhang Ye's detailed operations in flame control. In a short period of time, Sun Yi learned a lot of skills.

Then he saw Zhang Ye using a secret technique to perfectly fuse the various materials in the flame. The degree of fusion was definitely better than any previous time Sun Yi had refined the weapon.

"This is the normalization fusion method, and it is also a very powerful fusion secret technique. It can not only add to the fusion of materials, but also make the fusion of materials more perfect." Zhang Ye explained.

"Tsk tsk tsk, another great technique! If all the disciples in the production department can learn the Nine Revolutions Mysterious Fire Refining Method and the Unified Fusion Method, our assembly line efficiency will be greatly improved."

Zhang Ye couldn't help but look at Sun Yi. Only the sect leader Sun Yi would reveal such a powerful secret technique to his own people without hesitation. Other cultivators would hide such a powerful secret technique once they got it.

After the tempered materials were fused together, Zhang Ye began to shape them. This step also used a method called soul fusion shaping, which could greatly reduce the consumption of the soul and make the shaping more precise.

This is another secret technique that can improve the efficiency of the assembly line. This thing must be promoted in the production department!

Next, Zhang Ye displayed extraordinary skills in carving the patterns on the weapon and the final seal, fully demonstrating the foundation of a major weapon refining sect.

Before, Sun Yi was very confident in his weapon refining ability, but after seeing Zhang Ye's weapon refining techniques, Sun Yi felt that he was just a graduate of a vocational school, and there was still a big gap between him and the talents of those top professional institutions.

But Sun Yi was not discouraged at all. After all, Zhang Ye, a fourth-level weapon refiner, was right next to him. He just needed to spend more time learning the weapon refining technique from Zhang Ye.

Now everyone's attention is focused on a body-tempering blood pool in front of Zhang Ye.

This body-tempering blood pool is silver-white in color and is a square pool. It is impossible to tell what it is made of, but the pool exudes an aura that can only be emitted by a fourth-level spiritual weapon.

The pool was covered with mysterious patterns, including patterns of instruments, arrays, and runes. These patterns were intricate and interwoven together to form a very complex pattern.

"The refining was successful!" Gu Qingcheng looked at the body-tempering blood pool in surprise.

"Let's try the effect quickly!" Palace Master Yan couldn't wait to try it, and the others also became nervous.
