"Welcome, professional technical sergeant mechanic Ji Xinghe."

When the electronic prompt sounded, the metal gate of the machine repair area was opened to both sides, and Ji Xinghe slowly stepped into it. And Su He, who was following him, frowned a little dissatisfiedly when he heard the name of Ji Xinghe in the electronic voice.

The promotion of military ranks is a matter of course, at this time, only one day has passed since Ji Xinghe returned to the sixth base, and the statistics of military merits have not really been completed, but he has achieved another two consecutive promotions.

But the strange thing is that Ji Xinghe's military rank still has the prefix of professional technology, similar to Shen Mu's professional technical second lieutenant, not the military ranks of Major Han Li, Major Jackson, and Second Lieutenant Li Lin. From a certain point of view, this shows that the superiors still hope that Ji Xinghe will honestly be a mechanic and stay in the relatively safe base to repair mechas, instead of appearing on the battlefield as a mecha warrior.

"In two days, you should be a second lieutenant." Su He was worried that Ji Xinghe was a little dissatisfied with this, and said with a smile: "Twelve Venus, the cripple and the blind man have only been on the alien planet for so many years, Lao Ji, you have only left the base twice and have already obtained it, and you have become an indisputable first-class mecha warrior, and the two of them will definitely be proud of their prescient worship of you as a teacher." ”

Under normal circumstances, the first-class mecha warriors of the Federation can get the rank of second lieutenant, and they are directly promoted from sergeant to ensign, and the sergeant major between the two ranks can be directly crossed, which is one of the benefits of mecha warriors.

"It's a pity I didn't teach them anything." Ji Xinghe responded, his tone was calm and his expression was natural, and he didn't seem to have any dissatisfaction because of his rank prefix. On the first day after coming back, except for an hour in the medical area to inject glucose and nutrients, he spent the rest of the time by Ji Rong Xinyue's side, and it was not until today when Ji Rong Xinyue went to class as usual that he came to the machine repair area.

"They say you've taught them a lot."

Su He followed Ji Xinghe and kept talking, Ji Xinghe kept answering, and the two of them came to the No. 139 operation area while talking, the original person in charge of this operation area had been transferred to the real front-line military camp to repair the mecha before the dust storm, and there were more than 20 people in charge of the operation area, so the operation area of the No. 6 base machine repair area was vacant a lot.

As the two walked in, they could clearly see a mecha parked here, the overall paint was orange-red, which looked no different from the most common colors on the surface of aliens. The first impression is that it is bloated and fat, so that it is impossible to see the neck of this mech, and the head of this mech is proportionally smaller compared to its tall and bloated body.

The limbs are very thick, and the feet support this mecha standing on the metal ground, and the fists at the ends of the two arms look bigger than the casserole. There are no weapons on the torso, no miniature missile launchers, no miniature machine guns, only idle hardpoints that do not function clearly.

On the shelf next to this mecha, there is a 2.8-meter-long mecha battle knife, which is the one that Ji Xinghe took back from the battlefield, not to mention the characteristics of high-frequency oscillation, and the materials used in it are also very precious, and they are still as clean as new after I don't know how many battles.

Ji Xinghe's other battlefield harvests were all pulled back by the logistics department, but they were not sent to Ji Xinghe here, but stored in the relevant warehouse, and this war knife would also be taken away according to the relevant regulations, but at the insistence of Instructor Li and the mecha warriors who participated in the battle, it was sent to the mecha area and appeared next to Xingyue.

Yes, this bloated mecha parked in the operation area of No. 139 is the mecha designed by Ji Xinghe as the main force, which can be said to be a replacement for the old man's music, or it can be said to be an upgraded version of the old man's music.

"Xingyue is only four meters tall, but this war knife has a length of two meters and eight, and the height of the Imperial mecha standing with this one is 4.8 meters, so will this change in height affect your use of this war knife? It seems to me that if Xingyue held this war knife in his backhand, the tip of the knife would stick to the ground. Su He asked while filming with a camera next to him: "Lao Ji, I don't understand this aspect, you can tell the audience." ”

Ji Xinghe groaned slightly, he actually didn't want to talk to the audience about this problem, because the audience was not a mecha warrior, and they didn't need to know about it. If someone can really join the army, there will be systematic teaching and training in the army. If you are admitted to the mecha piloting major of the relevant military university like Ji Chenxing, then the knowledge you can learn will be even more professional.

But to be reasonable, the reason why he was able to come to the alien star was that he agreed to Tu Yuan's middle strategy, although he had already shown strength beyond everyone's expectations, and made contributions that no one had thought of before, but Tu Yuan still had the ability to send him a blue star at any time. Or confine him to the base and let him finish filming the documentary "The Old Man and the Sea of Stars" alive, the method is very simple, just don't give him a mecha.

This is the reason why Xingyue appeared, but Xingyue is really not good now, Xingyue is completely made of discarded parts, and there is a risk of falling apart at any time. If Ji Xinghe had left the base to fight in the dust storm this time, and Ji Xinghe was driving Xingyue, he felt that it was unlikely that he would be able to defeat nine mechs.

"It won't matter, because the mech's arms can be raised." Ji Xinghe looked at Xingyue and replied: "If it is a person of the same proportional height, it will definitely not work to use a war knife of the same proportional length, and many knife skills will not be able to be used, because the blade is too long, it is difficult to retract the knife in time, and if you can't retract the knife, you can't exert your strength again." But the mecha is different, first of all, the mecha has unlimited physical strength when the energy is sufficient, and it will not feel tired. The second is that the explosion of the mecha relies on the engine core, although the power of the knife is definitely stronger after the knife is closed, but many times it is not necessary to completely withdraw the knife to launch a second attack. Finally, mech combat doesn't require too complicated knife skills, and in my experience, only eight moves are enough. ”

Su He asked, "Which eight moves?" ”

"It's not eight specific moves, it's eight methods, Eun...... Do you know how to write Yongji? Forever and ever. ”

"Yes."

"Have you ever heard of the Yongzi Eight Laws?"

"I've heard of it, those who practice calligraphy generally practice the eight methods of Yongzi."

"That's it, people who are generally good at calligraphy will be described as moving the pen like a knife, and the opposite is the same, moving the knife is like a pen, and the eight laws of eternal words."

Su He didn't seem to understand it, but it didn't matter to him, it was just to record relevant material.

"Then old man, would you use this kind of knife? You're not good at eight slashes, aren't you? Su He asked again: "Why don't we contact and exchange this war knife with two eight slashing swords, anyway, your eight slashing swords are very short, they are only one meter long, and there is still money to be earned in the base." ”

Ji Xinghe was not amused by Su He's words, but explained seriously: "This is not only a matter of the material of the blade, but also the most important energy core and related parts, otherwise the war knife cannot have the characteristics of high-frequency oscillation, and if it can't be exchanged, I'll use it first." ”

Su He gave Ji Xinghe a look, indicating that he actually knew this, and he only asked this for the sake of popular science for the audience. After that, there were some questions and answers, so that Su He accumulated a lot of materials, not to mention the third issue of "The Old Man and the Sea of Stars", the fourth issue is enough.

As soon as it was over, Shen Mu walked over with an indignant face.

"Lao Ji, they don't change the twelfth generation engine, saying that they can only change the eleventh generation engine."
