Early the next morning, Chen Zhengjie received a signing order, this time it was a modification plan led by him, and the two mechs transported by the alliance could only be used by him to sign the receipt.

After the receipt was signed, the staff of the Star Defense Academy helped open the outer sealed metal cabinet of the mecha, and the two mecha were quickly presented in front of Chen Zhengjie, the shape of this advanced 5th generation mecha is really cool, and the overall model is full of power, but Chen Zhengjie does not have much time to appreciate this mecha, he has more important things to do.

Whether the intermediate mecha can be modified into their own expectations depends on the effect of this modification, only after the intermediate mecha is successfully modified can the advanced mecha be modified accordingly, the senior mecha of the colleague has been temporarily authorized, Chen Zhengjie can go up to experience the operation and then modify the entire mecha, otherwise what performance parameters and operation are not clear, the modification may be a snake.

The mid-level mecha was fixed to the repair table, and the two arms were removed with a robotic hand, and then it was a subtle operation, the weapon energy conversion device and output line on the waist and back were carefully removed, and then the external armor of the two arms was removed.

After the dismantling, Chen Zhengjie carefully measured the data of the metal skeleton in the mecha, and then made continuous optimization according to his own design drawings, after all, if he did not measure carefully, the weapon energy conversion device would fail after being installed, and he had to take into account the maintenance and replacement situation, otherwise the mecha could only throw stones at the enemy after using the energy core in this area, so it was necessary to make changes to facilitate replacement.

After some revisions and modifications, the design pattern of Chen Zhengjie's entire mecha arm part finally met his ideal requirements, but the specific needs to be optimized and modified in the process of modification.

Manufacture the mold according to the design drawing, and then pour it into it with a wax object, wait for it to cool and solid, carefully take it out and put it on top of the inner metal skeleton for installation, and melt or pour the wax liquid according to the problems found, the whole process will continue to melt and pour the process, which is also Chen Zhengjie to do a good job in this modification, after all, there is a high-level mecha waiting for him to modify, and after a successful experience, the modification of the high-level mecha is basically not a matter of hand-to-hand.

There is basically no problem with the external armor, Chen Zhengjie's next thing is the installation of the casting weapon energy conversion device, it cannot be a weak position of protection, nor can it affect the operation of the mecha arm, and the output line must be installed in place, this series of work is even Chen Zhengjie's strong body and attention are a little unbearable, and this is the first day of modification work, which is completely different from when the original generation was modified, the first generation of aircraft said that it is difficult to hear too much space that can be used, He only needs to cut some of the required parts into shapes with gold lasers, and there is basically no requirement for aesthetics, only when this set of modification plans is transplanted to the first 9 mecha, the visual effects have been changed, but this time Chen Zhengjie has completely considered the aesthetic effect of the mecha on the intermediate mecha, and this aspect has also been directly added.

After a night's rest, Chen Zhengjie continued to modify the intermediate mecha the next day, and today's main task is to test the stability of the weapon's energy conversion device, but this aspect is still a waxy external component for the time being, so the range of action cannot be too large, otherwise yesterday's efforts will be in vain.

The test process went very smoothly, but because the wax armor was delayed a little when replacing the energy core, after all, if you don't move slowly, the wax armor will shatter.

It can be finalized, Chen Zhengjie is carefully dismantling those waxy parts one by one to prepare for the final metal mold, at this time he needs the help of the metallurgists sent by the alliance, this piece of terminology technical work, Chen Zhengjie will not be a genius to any field There is no problem, after all, the metal formula of the intermediate mecha is still in the hands of the alliance, and these students only know the hardness of the metal, the amplitude of resistance and other data, even if it is a test, they can't know the formula ingredients in this regard, So it's up to metallurgists to help with these things.

It took a whole day to make the mold successfully, and then it was not Chen Zhengjie's business, he could eat and sleep and beat his teammates.

On the third day, the metallurgists finished manufacturing Chen Zhengjie's finalized mecha parts and the parts needed for the external armor, followed by Chen Zhengjie's assembly and wiring process.

Looking at the brand-new mid-level 9th-generation mecha in front of him, Chen Zhengjie couldn't help but smile, this is the time for him to complete the mecha modification by himself alone in the true sense, and go to test the effect.

After reporting to the garrison next door, Chen Zhengjie drove the mecha to their training ground for actual test work.

The rapid fire of the beam cannon, the accurate spot fire of the assault rifle, the accurate sniping of the sniper rifle, and the use of melee weapons are very successful in all aspects, and even the rapid replacement of the energy core on the battlefield is easy, you must know that the replacement of the energy core on the battlefield in the past requires the cooperation of two mechas, but there is a very creative change in Chen Zhengjie's modification this time.

A button is set up at the place where the energy core is placed, press the button when you need to replace the energy core, and the armor outside the energy core will open a small hole that can only pop out the energy core that has run out of energy, pull out the core and install a new core The metal cover can be automatically closed. On the battlefield, if you want to shoot accurately, the probability of hitting this replacement hole is only 1 in 1%.

This change can be said to be a stroke of genius, even the professor of the Star Defense Academy couldn't help but admire it when he saw it, in fact, this kind of small technology is not something that no one has thought of, but no one would have thought of installing the inherent weapon energy conversion device of the mecha on the upper limbs of the mecha, and then the use of this small technology can naturally be placed on it, which is the technical improvement that affects the whole body.

Just imagine that when fighting on the battlefield, in the past, before the energy was about to run out, contact the nearest comrade-in-arms first, and then two people hit a piece and a mecha helped to take out the energy core and take a new piece to install it, which will delay a lot in this time, and the attack area of the two mecha will become much larger when they are close together.
