"Is this the list you finally selected?" The lieutenant colonel couldn't help frowning as he looked at the list of members handed over by Gu Feng, "Is 18 people a little too little?"

Can you complete the military mission?"

Gu Feng smiled faintly, "18 people is not a lot at all." The main thing is that the refining technology of red gunpowder has high requirements for spiritual power, and only these people are eligible at present. In addition to the innate technical limitations, it is not difficult to manufacture red gunpowder once it is learned, and 18 people are more than enough, and it will definitely not be wrong. I can guarantee that I will be able to refine at least 500 kilograms of red gunpowder in a month, and 1,000 kilograms is not impossible! The key depends on how quickly they learn?"

"I see!" the lieutenant colonel nodded at the hearing.

Again, professional things are left to professional people.

Since Gu Feng said so, he wouldn't interfere more.

Everything speaks for itself.

If you don't meet your promise in the end, you will be punished at that time.

You must know that there is no joke in the army.

"In that case, your alchemy team should start preparing immediately. I look forward to seeing your results in a month!" The lieutenant colonel looked at Gu Feng and said meaningfully, his words full of expectations.

Gu Feng nodded and smiled slightly, calm as usual.

Seeing that he had such self-confidence, the lieutenant colonel couldn't help but have a little more confidence in him.

Then he led many soldiers to leave, the candidate had been decided, and he did not interfere with Gu Feng's next arrangements.

For a while, there was silence in the alchemist, and there was silence for a long time.

The eighteen people who stayed behind were all happy, they all failed to refine the medicine, and they thought that they would definitely be eliminated, but they didn't expect to be selected in the end.

Even they themselves find it incredible.

Gu Feng's eyes glanced at everyone, and the audience was silent, looking at him with apprehension.

They knew that this one was ruthless, and they didn't dare to fix the other moths.

This military mission was rewarded, and it was hard to stay, and if he was kicked out again, there would be no place to cry.

Seeing this scene, Gu Feng nodded.

The people who stayed behind were not only strong enough in spirit, good in alchemy skills, but most importantly, obedient enough.

That's what he values most.

Those thorns that don't know the height of the sky have long been eliminated by him.

Facing this pair of expectant eyes eager to learn new alchemy knowledge, he didn't make a fool of himself, and spoke directly, "After this simulated alchemy, you should also know that there are few advanced skills in the refining of red refining gunpowder solution, and the most critical step is my original crystallization pharmaceutical technique, which is the key to making the medicine truly qualitatively transformed, and it must have sufficient spiritual power as a basis to succeed in refining." Congratulations that you have stayed, it means that you have reached the innate conditions for refining medicine, and then I will explain to you in detail the tricks of refining red refining gunpowder one by one!"

When many alchemists heard this, they couldn't help but hold their breath and concentrate on it, for fear of missing every detail.

"The trick of Jinghua Pharmaceutical is to use mental power in this technology. The crystallization of this red practice gunpowder needs to be divided into three steps, which are spiritual perception, mental operation, and spiritual temperature control. Spiritual perception is to perceive the medicinal properties of drugs all the time with mental power and make detailed adjustments. Mental manipulation is the mental power that controls the combination of medicinal molecules, allowing them to achieve a stable crystal structure and lock in the medicinal power. And the standard of red gunpowder is the most perfect and stable hexahedral structure, only in this way can the violent medicinal power be suppressed and will not burst violently. But this is not enough, you also have to do the most crucial point, which is to isolate the solution with mental power, evaporate in pieces, and finally form sand. The third step is mental temperature control. The medicinal properties of red gunpowder are too unstable, and it is very easy to cause an explosive reaction when crystallized, and every increase in temperature may cause chain terrible consequences. At the time of crystallization, it is necessary to adjust the flame temperature at any time to achieve the final product. Crystallization is an incomparably sophisticated skill. The difference is a millimeter, and the error is a thousand miles. You have to be the best at every step, and the slightest mistake is a failure. ......" Gu Feng commented one by one, explaining the technique of red gunpowder in simple terms, and teaching the profession.

When those alchemists heard this, they suddenly had a sense of enlightenment.

But this is not over, Gu Feng said again: "The reason why you failed to refine medicine before is because you only know how to perceive and manipulate spirits, but you don't know anything about spiritual temperature control. Look, I've only shown it once, and if you miss this opportunity, you'll have to figure it out for yourself!"

As soon as he said this, everyone immediately stared at every movement of Gu Feng's hand wholeheartedly.

At this time, his handprint had been pinched again and again, and he saw a flame under his control, constantly changing, sometimes flames, sometimes quiet as water, sometimes spinning like wind......

The most ordinary flames have reached various forms, and the control of fire power has reached the wonderful realm of doing whatever you want, turning decay into magic.

Those alchemists remembered the changes in their handprints, felt the spiritual fluctuations permeating the void, and learned them one by one, wanting to master this strange spiritual ability as soon as possible.

Gu Feng had already finished the demonstration and did not make another move.

As the team leader, he has his own identity, and he is not the nanny of these people.

Being able to witness the key to crystallization and pharmaceutical technology with his own eyes is a great opportunity for these alchemists, if he doesn't know how to cherish this, there is no need for him to keep this kind of person anymore.

Fortunately, the rest of the people were smart enough, and they were extremely fast to get started, and no one dared to be distracted in the slightest, and Gu Feng also nodded with satisfaction.

Immediately after that, under his guidance, many alchemists began to try to refine red refining gunpowder again.

There are all kinds of materials in this high-level alchemy room, and you can use them at will, and you can keep practicing until you succeed.

In order to cope with the next ghost war, the Great Wall Army attaches great importance to the big killing weapon of red gunpowder, and in order to obtain a large amount of gunpowder, it is already at any cost.

Gu Feng continued to guide on the side, constantly pointing out the mistakes and omissions of their refining techniques.

With the supply of a large number of materials, these eighteen people are getting closer and closer to the success of the last step, and only half a day later, someone has refined the sand for the first time, although it finally exploded, but it is only one step away from success.

Gu Feng also nodded again and again.

Once these people are successfully refined, they can relieve him from the heavy task of refining medicine, and he just takes the opportunity to do some things of his own.

Gu Feng seemed to have seen the scene of his promotion to lieutenant a month later.
