The science and technology warriors in the second row, the student number is nine thousand away, and they were born less than half a year earlier than Lu Haoyu, in the Heavenly Dream Regiment, how could they have seen such a sharp plate axe, and they were frightened by Lu Haoyu's roar, and the plate axe changed hands.

"You think an axe like this is sharp enough? Can I use it? ”

The soldiers stared at Lu Haoyu, although they didn't reply, but the implication was, "Isn't this enough?" ”

"It depends on what you're used for, but if it's just chopping wood, that's probably enough. But if you want to use this axe as a weapon, it's still far behind. ”

Then Lu Haoyu pinned the axe to his waist and said to the veteran next to him: "The grinding stone is not enough, I still need two." ”

This was the old soldier who had just been put on his neck with an axe, and he was frightened and obeyed Lu Haoyu's words.

The new grinding stone was held by Lu Haoyu in his hand, and he once again improved his charm by disseminating scientific and technological knowledge.

"Let's take a look at the surface of this grinding stone, because it has been polished for a long time, it has been completely smooth. If we magnify this grinding stone a hundred times with a magnifying glass or a microscope, you will definitely find that the crystal particles on its surface, all the edges and corners have been smoothed, so that the surface is so rounded. This can no longer be called a grinding stone, we can call it a polishing stone. ”

The soldiers listened to it like a book from heaven. But fortunately, Lu Haoyu is articulate, quick thinking, and can simplify complex things, even if everyone doesn't understand high-end technology products such as magnifying glasses and microscopes, but at least they can understand what he said.

"So does this polishing stone have no meaning and can be thrown away? My answer is no, it's still useful. Depending on the needs, this polishing stone can be used as the final polishing product. ”

"Finished polishing?" The warriors were taught a new technology, and everyone listened attentively.

"Every weapon, before it is produced, should be polished, and this polishing has two benefits, one is to repair the surface scratches of the sharp weapon."

Lu Haoyu said, picking up the plate axe and turning over to another unpolished axe surface, you can still see scratches left by the grinding stone on the axe surface, and the purpose of polishing is to smooth out these scratches.

"The second is the polished weapon, which will be removed by the oxidized component, which will make the sharp weapon appear its original metallic luster, simply put, to make the object brighter."

The soldiers were like listening to a book from heaven, and they were all stupid. For their performance, Lu Haoyu didn't understand at the beginning, although most of this knowledge came from the download of the essence of science and technology, but it was not to worship to this extent, after all, these are basic knowledge.

Gradually, Lu Haoyu thought of the cause and effect, the technology he mastered was a combination of Huanyu and Bingyu, although this is nothing in the eyes of human beings, but in the field of small soldiers, every technology will be a hundred times more difficult for them. Especially for a mercenary group that has not graduated from college and has just spent two or three years of middle school.

Because the master of this world is not a soldier, it is a human being, all the material here is centered on human beings, and the small soldier is the epitome of one percent of the human race, and the development of science and technology after a hundred times is reduced, which will undoubtedly greatly increase the difficulty.

Take the grinding stone as an example, the grinding stones of the science and technology company are large and small, and there are any shapes, the prototype of these stones should be from the handwriting of the master Ye Guchen, but he can only make the grinding stone into the shape of a large stone slab, and then the grinding and processing of the soldiers over time to form the prototype of the grinding stone.

The original grinding stone is not round and smooth, the section of the grinding stone, the crystal is extremely coarse, and it can't even be used as a grinding effect, the soldiers haven't thought about Lu Haoyu's method, but opening the cup with bare hands can't achieve Lu Haoyu's smooth cutting level.

"You, let's give it a try." Lu Haoyu handed a grinding stone to the warrior again.

Looking at the veteran, he hesitated, not daring to start.

"Your forging level won't even break a stone, right?" The grinding stone that Lu Haoyu handed to the veteran was very thin, but no matter how thin it was, it was a stone, and Lu Haoyu could easily interrupt it, but the soldiers of the technology company couldn't do it.

"Use this to smash", Lu Haoyu handed him the axe, and behind the axe was an axe with a large contact surface.

The veteran took the axe, used all his strength, and finally broke the grinding stone, but the interface was uneven, far from reaching the level of Lu Haoyu's flush cross-section.

"Bring me a few more grinding stones." Lu Haoyu sighed and shouted pity.

The veterans looked forward to it, hoping to get Lu Haoyu's guidance.

"You're barely strong, but the heat is far from it."

The fighters shook their heads to indicate that they did not understand.

"The power should be used intensively, and your spiritual power should also be integrated into the hands of the force, the power of the control hand should be concentrated on the first line, and finally the diffusion and convergence of the explosive force should be controlled. Got it? ”

The fighters shook their heads.

"If you don't understand, repeat what I said ten times, remember the main points, and then train repeatedly, your body forging cultivation is too small, if your qualifications are really too poor, find other high-level body forgers to help."

"Concentrate your strength, concentrate your spirit, concentrate on the front line, control the explosive power, and converge..."The soldiers were really obedient, and they silently took stones to practice one by one, they didn't dare to use grinding stones with good materials, and they were also skeptical of Lu Haoyu's words.

But Lu Haoyu was full of confidence, his theories were not casually said, but the mastery of the basic strength in the basic forging body. The content of the essence of science and technology is categorically not wrong.

finally sent the soldiers away, leaving only Hou Xiaoxian by his side.

"Why don't you go and practice with everyone?" Lu Haoyu always felt that this person was not ordinary.

"You mean the one-handed opener? The old tattered hands are fragile, so they don't mix with the young. ”

"Why do you always say that you are old, how old are you?"

"Hehe, it's actually not that big, it's just less than three years before you."

When Lu Haoyu heard this, he scoffed. It's only been three years, and he dares to put on old qualifications, he thinks Hou Xiaoxian is too pretentious.

"Your student ID is 9527?" Hou Xiaoxian was very angry when he saw Lu Haoyu's disdainful look.

"yes."

"My student number is 19"

"So what?" Lu Haoyu laughed even more, thinking to himself, this is showing his qualifications.

"There is only one person left alive in front of me, and that is Instructor No. 7 Jia Mengyun."

Lu Haoyu was stunned for a moment when he heard this information, "What about the other 17 people, all dead?" ”

Hou Xiaoxian's expression was very strange, he hesitated for a long time before whispering to him: "Not only are they all dead, but even the students behind me were all killed in a natural disaster more than half a year ago..., in short, except for Jia Mengyun and me, the top student number of the all-day dream group is Shi Xiaotian, the head of the group, 9001."
