Li Qingyu and Lin Jingya left the Cai family the next day. Li Qingyu returned to Hengzhou City and continued to be busy with the Lingdan production line, while Lin Susu returned to Jinhai City and was busy with her own affairs.

With the formation, Li Qingyu had already gained a deeper attainment. A month later, he finally developed a formation that could cover up the secrets of heaven.

There are five production lines in the alchemy plant, each with ten alchemy furnaces, and a total of fifty alchemy furnaces. Although Li Qingyu has studied the results, he has not practiced it yet and has learned the lesson of the first accident. Therefore, he did not portray formations on all the fifty alchemy furnaces.

The alchemy furnace is very precious, and the medicinal materials for alchemy are even more precious. Once it fails again, the loss will be too great.

He first carved the formation on a elixir furnace, and then embedded a piece of spiritual crystal to provide energy to the formation.

During the days when Li Qingyu was studying the formation, Yue Zhimei and Li Ruitong were not idle either. They were looking for raw materials for alchemy all over the world.

Refining elixirs has very strict requirements on medicinal materials. Every time they purchase medicinal materials, they personally checked according to the medicinal materials standards proposed by Li Qingyu, and did not dare to be careless at all.

To be on the safe side, after Li Qingyu and Li Ruitong discussed, they no longer refined the foundation-building pill, but first refined the Qi Condensation Pill that was one level lower.

Li Qingyu wanted to improve the realm of the Niu Family's Detachment Army first. After this period of accumulation, they were all stuck at the bottleneck of the Qi training realm. Li Qingyu believed that as long as there were enough foundation-building pills, they would definitely be able to break the bottleneck and enter the foundation-building realm.

The foundation-building realm and the Qi training realm are two levels of Yunni. Strictly speaking, before the foundation-building, even if everyone practices cultivation techniques, they cannot be considered cultivators. They can only be considered a relatively powerful martial arts master. Only after building the foundation-building can they truly enter the hall on the road of cultivation, and from then on, they will be truly called cultivators.

If all the sixty-nine members of the Niu Family Detachment Army became masters of the foundation-building realm, Li Qingyu naturally had great confidence. Even if the hidden family came with a more advanced killer, he could still sit in the central army tent and deal with it calmly.

The function of the foundation-building pill is not that it can only help monks at the ninth level of Qi training break through the bottleneck and enter the foundation-building realm. After the monk enters the foundation-building realm, he will continue to take the foundation-building pill, which can still help monks advance quickly.

Because the foundation-building pill has so many benefits, Li Qingyu wanted to refine the foundation-building pill in one step before. The result was not only failed, but also caused serious consequences. Therefore, now he dare not refine the foundation-building pill in one step, and changed it to refine the Qi Condensation Pill with one level of difficulty.

Qi Condensing Pill is also a thing that goes against the sky. Now Lin Jingya, Ning Rourou, Xiaozhu, Liu Jiayi, Deng Yuqi, and Acheng Axin, Wu Qingshui and others all need a large amount of Qi Condensing Pills.

Of course, if we included the Galaxy Fleet on Zhou Xianguang last year, the gap would be even bigger!

After they were ready together, Li Qingyu specially chose a good day and put the selected medicinal materials into the alchemy furnace. Then the upper and lower hemispheres were combined together, and the alchemy furnace was closed and turned into a ball, like a chemical reactor.

Each production line has a special monitoring room, and each alchemy furnace has a monitoring screen, which displays various parameters in the alchemy furnace. Moreover, because there are special cameras in the alchemy furnace, you can clearly see the scene inside the alchemy furnace through the monitoring screen.

Li Qingyu, Li Ruitong and Yue Zhimei stood together and monitored the situation of Furnace No. 1 together.

Through the monitoring screen, they clearly saw that when the upper and lower hemispheres closed, a nozzle sprayed out a slightly viscous liquid. This was a pre-boiled medicine liquid that could help the herbs in the furnace to dissolve quickly, turning from solid to liquid.

After adding the liquid, the herbs in the alchemy furnace floated up. The heating system of the alchemy furnace started, the liquid inside boiled, and water vapor rose, and the air pressure in the alchemy furnace began to rise continuously.

Under the high temperature and high pressure and the dissolution of the medicine liquid, the herbs they added in advance also began to dissolve, and the liquid became more viscous than before.

Li Qingyu looked at the clear display in front of him and couldn't help but smile at Li Ruitong beside him, "Brother Li, you are really a genius! You use modern crafts to refine pills and have designed such a great equipment by yourself. I feel that you are really an alchemy genius!"

Li Ruitong smiled bitterly and said, "Hehe, if you said these words from others, I will definitely be very happy. If you say them from you, I feel a little awkward."

"Why? I'm sincerely praising you." Li Qingyu said with a smile.

"Haha, except for this set of equipment, I have done our alchemy business. Aren't you all provided the materials and methods of boiling the other elixirs? If I am also a genius in alchemy, what are you? So, whenever you say that I have good alchemy skills, I feel that you are boasting, not praising me." Li Ruitong laughed.

"Okay, I just think you are praising me."

Refining pills is a long process, and naturally it cannot be achieved overnight. As time goes by, Li Qingyu and the other two are becoming more and more nervous, fearing that the alchemy furnace will cause the heavenly disaster again!

Fortunately, with the first explosion experience, they knew that the explosion of the alchemy furnace was not very powerful. As long as they hid in the monitoring room and did not get close to the alchemy furnace, there would be no major problems.

Fortunately, everything was safe. Until nine days later, the liquid in the alchemy furnace was completely mature and when you could start making ointment, everything was calm and there was no divine disaster at all.

Only then did Li Qingyu and the other two completely relieved - the formation that covered the secrets of heaven was effective, and they succeeded!

Li Qingyu personally operated it and began to pressurize the elixir furnace, then opened an exquisite valve under the elixir furnace. Outside the valve was a pipe as thick as a thumb, like a faucet.

Under pressure, the ointment in the elixir furnace flowed out of the pipes and was injected into round molds. When the ointment solidified in the mold, Li Qingyu gently broke the mold and took it out of the mold. The light red condensation pill of the same size as a grape was completed.

The success of the first furnace made Li Qingyu very excited. Next, he asked the factory's production line operators to operate, Yue Zhimei and Li Ruitong to supervise, while he himself began to carve formations on other furnaces. Every time he carved one, he started to produce one.

The refining process of Qi Condensing Pills was very smooth and very productive. Li Qingyu refined 936 pieces in one breath before finally stopping. With these Qi Condensing Pills, it was enough to send Lin Jingya, Deng Yuqi and others into the ninth level of Qi Training!

After each Qi Condensation Pill is completed, many drugs will be left in the alchemy furnace. Because the efficacy of the medicine is reduced, these residues can naturally be made into Qi Condensation Pill, but they cannot be wasted. Li Qingyu refined them into the "Resurrection Pill".

The refining process of the Resurrection Pill is much simpler. Everything is done in just two days. They finally mastered a total of 1,200 "Resurrection Pills"!
Chapter completed!
