Everyone was waiting quietly, and Zhou Likun became nervous. Although he was very confident before, Feiyu Zhenren was a master of the Nascent Soul stage after all, and he could not tell the problem. After all, this foundation-building liquid was just a new thing, while the foundation-building pill in the past had been tested for hundreds of thousands of years.

To put it bluntly, the foundation-building pill is to "stimulate, activate, enhance" the human potential and make the body potential "boil and rise for a short time" to overcome the level.

But there is a problem here: medicine is three parts poisonous. But some medicines are not three parts poisonous, but seven parts poisonous, and can even poison for a lifetime. What Zhou Likun fears most is that this foundation-building liquid has implicit and unknown toxins. As the successor of alchemy, Zhou Likun does not allow imperfect things to exist. Therefore, Zhou Likun is also preparing to conduct clinical trials before promoting it.

As time passed by little by little, Li Xian became nervous. The emergence of foundation building liquid will directly affect the future development of Anyang. Think about it, when resources in other places are generally scarce, there will be spiritual liquid and foundation building liquid here in Anyang. What will happen?

From now on, the streets of Anyang will be full of foundation building stages; there will be no Qi Refining Stage in the army, and all the Foundation Building Stage masters will scare the enemy to death! At that time, others' million-dollar army will be in Qi Refining Stage. Although there are only 100,000 troops in Anyang, all the Foundation Building Stage masters and everyone has magic weapons. What will happen? It makes people excited to think about it.

Once the spiritual liquid is available, and another foundation-building liquid is added, isn’t it just that we will live together?

But if you want to achieve this goal, it depends on the quality of the foundation building liquid now. Zhou Likun was nervous, and Li Xian was even more nervous.

Xia Qingqing leaned gently beside Li Xian and waited quietly like Li Xian.

Time passed little by little, and a little white mist overflowed from the head of Feiyu Zhenren. It was a sign of the boiling blood and the boiling true energy in the body.

Suddenly, Feiyu Zhenren opened his eyes, and a flash of lightning rushed out of his eyes and cut off the ordinary account book ahead; but no one cared about these details anymore, and everyone looked at Feiyu Zhenren, waiting for Feiyu Zhenren's answer.

Feiyu Zhenren slowly stood up and nodded to Zhou Likun: "Very good, this pill liquid can be used completely. There is only a little problem."

A small question?

Zhou Likun's excited expression immediately became nervous.

Feiyu Zhenren thought about the words and said: "My feeling is that this elixir lacks the calmness and thickness of the elixir. This is caused by the essence of the elixir and the elixir. I wonder, can the storage time of the elixir be increased and ferment it like aged wine?"

Li Xian asked, "Senior, what are the consequences of lacking calmness and weight?"

"It will impact the mind and make the cultivators feel a little irritable when they break through. Some people with low minds may even go astray. However, because of the lack of spiritual medicine, many people are now down-to-earth in their cultivation, and this shortcoming can basically be ignored. But they have to be careful."

Zhou Likun was overjoyed: "Thank you for your advice for your advice. This is also very simple. Just increase the time to boil the pill liquid, and add a little spiritual liquid with soil attributes, or spiritual materials."

Zhou Likun started to be busy after he finished speaking. With Feiyu Real Person present, he had to use it. As for the cut-off account books, someone had already spliced ​​them.

After less than half an hour of busyness, Zhou Likun brought three kinds of elixir liquids, one to increase the boiling time, one to increase the earth-attribute spiritual liquid, and the other to "boil and add a little earth-attribute spiritual liquid."

Feiyu Zhenren tried every thing, "Those who increase the boiling time have not been very active, and the effect is three points worse, but they are indeed much calmer, which seems to be different from the real foundation-building pill. Those who increase the earth-attribute spiritual liquid have not had a very good effect. Change the formula of the pill at will to slightly change the effect, and have a little depressing smell, which is not desirable.

But it is best to boil this kind of boiling and adding a little earth-attribute spiritual liquid. During the boiling process, the slight changes in the medicine liquid will be offset."

Everyone looked at Li Xian - Young Master, you should have slapped your head, oh oh oh, it was the decision.

Li Xian thought for a while, "The production of two kinds of spiritual liquids, one is simply boiled, divided into inferior and sold to the outside. The other is boiled and added with a little earth-attribute spiritual liquid, and it is used internally and not sold."

"Okay." Zhou Likun responded immediately, and the next step was to design the production line.

Xia Qingqing said softly: "Husband, can this foundation-building liquid be sold to the outside world? Are you not afraid of causing trouble?"

Li Xian smiled helplessly: "After all, paper cannot contain the fire. If we open the foundation building liquid to the army, there will always be rumors. In this era of scarce resources, if we suddenly improve collectively, others will definitely have ideas. Since this is the case, it is better to sell it publicly.

It’s not for sale now, but for a while when rumors appear, it’s not too late to sell it.

Of course this price, hehe..."

Li Xian had a trace of helplessness, insidiousness, or a villain's successful smile. Anyway, this smile was very complicated, and Mona Lisa would run away when she saw it - she felt ashamed of herself.

Later, I checked some other elixir liquids; there were all foundation-building liquids, and there were also many basic healing and auxiliary medicinal liquids. There were some that strengthened the foundation and cultivated the essence, some that activate the muscles and promote blood circulation, some that were general medicinal, and naturally there were also auxiliary practices; there were also the division of the species attributes of metal, wood, water, fire and earth.

The packaging of gold, wood, water, fire and earth is represented by: yellow, green, blue, red, and brown.

Then Li Xian looked at the refining, defense, etc. here again, and confirmed that there was no problem, so he hummed a cheerful music, walked back to the aircraft, and prepared to take off.

"What kind of song is this? I have never heard it before." Xia Qingqing was very confused. Where did Li Xian learn about these strange tunes?

Li Xian giggled: "Folk, folk. Hehe..."

"It's weird if you believe in you!" Xia Qingqing rolled her eyes.

Suddenly, an aircraft flew in the sky and someone shouted from afar: "Prince, the second type of engine in the flight laboratory has been successfully studied!"

"What?!" Li Xian was shocked and then was overjoyed. He developed the second type of engine so quickly. The so-called second type of engine in the flight laboratory is the "jet engine". It is just to keep it confidential to the outside world, and the technology is expressed by serial numbers.

The first type of engine is a propeller engine. Whether it is a formation engine or an internal combustion engine engine, it is divided into this category. Based on the current technical situation in Anyang, the formation engine is small and powerful, which consumes spirit stones; the internal combustion engine engine is bulky and powerful, but it does not consume spirit stones. Each has its advantages and disadvantages.

The second type of engine, the current injection engine, should be regarded as a super-evolved version of the internal combustion engine.

The power of the propeller engine comes from the propeller rotation and comes from the aerodynamics.

The power of the injection engine comes from the recoil force. For the time being, this is the field of pure physics, and the formation technology has not yet been extended.

But no matter what, the jet engine was successful, and Li Xian's heart began to jump unscrupulously. What does the jet engine mean? It means that it easily exceeds the flight speed of the Nascent Soul master, which means that it will go further from launching the rocket. Yes, rocket engine and jet engine are two technologies, but many principles are the same.

From the propeller engine to the injection engine elevation technology, the next step is the rocket engine.

Li Xian looked up at the sky and shouted in his heart: "I want to see what kind of world this is! The satellite launch has entered the countdown!"

Before the aircraft above landed, Li Xian directly directed the aircraft to fly to Qingyun Valley. As soon as he entered Qingyun Valley, he heard a familiar roar. It was the unique sound of the machine's super-high speed rotation, as if it was thunder, and it seemed that the war horses were neighing, as if the sword was unsheathed, and there was a faint sound of tearing.

"It's this sound! It's this sound!" Before he could get to the laboratory, Li Xian became excited.

The gate of the tall factory building of the flight laboratory opened, and the low roar was even more obvious. At first glance, there was no way to see Yun Feihong, but the directors of other branches, etc. Tang Rong was from the General Research Department, Peng Yongguang was from the Power Energy Branch, Yang Qianjiang was from the Arsenal, Liu Bin from the Machinery Factory, Xie Wenjie from the Locomotive Branch, Wan Sheng from the Ship Branch, Song Gang from the Smelting Branch...even Fang Shijing was at the scene.

Wait, there was another person who was very active and jumped around, and Ling Zhifeng was also watching the fun on the spot.

Among the current high-level officials in Anyang, Ling Zhifeng is the easiest and most active one. This guy usually runs around without much trouble; of course, from time to time, there will be little girls pulling Ling Zhifeng to ask for fortune telling.3
