(Thank you renlao7 for the monthly pass, toothbrush drop tip!) ）

A pleasant dinner lasted for more than two hours before it was over, of course, most of the time was in conversation, in which the content of the conversation mainly involved two aspects: one aspect should be regarded as homely, chatting about their recent situation, teacher Huang Shujian, good memories of the past, etc.; On the other hand, about the phantom mecha, Su Feichen and Xiao Lingyun did not directly participate in the design of the phantom mecha, and their understanding of it is only limited to the relevant information they have obtained so far, and they actually don't have a very deep understanding of the phantom, so naturally there are still a lot of questions in their hearts, and Ye Zhiqiu and Fang Shi are to solve the doubts for the two.

For his senior brother Su Feichen and senior sister Xiao Lingyun, Fang Shi admired it very much in his heart, when the two talked about the phantom mecha, it was completely as if they had become another person, and their demeanor was extremely serious, especially the senior brother Su Feichen, there was no laughter, and there was no dissolute words, it was difficult to associate with him before. As for the senior sister Xiao Lingyun, she let go of her coldness and became positive and enthusiastic, and she and her senior brother Su Feichen were no longer incompatible, but more like close partners.

However, after the topic of mecha ended, Su Feichen and Xiao Lingyun instantly recovered themselves, one crackled and unscrupulously confided in words, and made some rather exaggerated movements and expressions from time to time, while the other was cold and silent, and immediately went crazy when he touched the bottom line, and there was a great tendency to be uncontrollable. This made Fang Shi on the side feel helpless and headache.

After finishing dinner, Xiao Lingyun stayed at Ye Zhiqiu's residence, while Su Feichen and Fang Shi left Ye Zhiqiu's residence shoulder to shoulder, of course, it was mainly Su Feichen who hooked shoulders. There is no consciousness of being a major general at all. The military ranks of the four members of the division are not low, Fang Shi is the major at the bottom, Xiao Lingyun and Ye Zhiqiu are colonels, and Su Feichen is the highest rank of major general.

According to the relevant regulations between Snowflake and the military, the junior mecha designer will automatically receive the rank of major, the intermediate mecha designer will receive the rank of lieutenant colonel, and the senior mecha designer will receive the rank of colonel. Ye Zhiqiu and Su Feichen are both senior mecha designers, Xiao Lingyun is an intermediate mecha designer, and Su Feichen and Xiao Lingyun are higher than the corresponding mecha designers and have other special identities.

Before Su Feichen became a Snowflake Company, he was already a mid-level officer with military power—a battalion commander of the Imperial Fighter Battalion, and his rank had reached the rank of colonel. And now he is in addition to being a senior mecha designer at Snowflake. He is also the person in charge of the Snow Flower Company in the Third Military Region, and his authority in the Snow Company is much greater than that of the old man Huang Shujian. In addition to being a mid-level mecha designer of Snowflake Company, Xiao Lingyun also has another important identity - a special mechanic, and is currently the chief mechanic of a certain army on the front line in the Eastern Region. The general head of the maintenance of the mecha of the entire army. This time, the two of them were relieved to work. Naturally, it was to help the teacher Huang Shujian complete the phantom mecha as soon as possible.

Ye Zhiqiu was not in a hurry to start the retest of the Phantom Mecha. Instead, he first gave Su Feichen and Xiao Lingyun two days to rest and adjust, after all, the two of them also rushed to the Wolf Tooth Star all the way, and the two of them still need a more detailed understanding and familiarity with the specific test details. Therefore, the test should not be rushed, and if there is any mistake, it will be worth the loss.

In the next two days, Fang Shi did not have idle, first spent half a day with his senior brother Su Feicheng and senior sister Xiao Lingyun to familiarize themselves with the No. 6 experimental test base, and the remaining day and a half was to take the two of them into the No. 1 experimental area of the base, on the one hand, so that they have a more detailed understanding and familiarity with the phantom mecha, and on the other hand, the ground test has been completed The relevant data and the arrangement of the specific test after a comprehensive and detailed understanding and mastery.

On the third day, Ye Zhiqiu restarted the ground test of the Phantom mecha.

Fang Shi and the Phantom Working Group resumed their busy work, while Su Feichen and Xiao Lingyun were respectively responsible for the tasks of two key positions.

The ground test was nearing the end when it was aborted before, and if the remaining tests went well, it should be completed in about twenty days, but the last few tests had an important data test, which was also the key to the success of the phantom mecha test, which was the mecha's stealth ability test.

Stealth ability is an important research and development content of Huang Shujian's original research and development of the phantom mecha, and he has invested a lot of money and energy in the development of this area. Of course, the so-called stealth ability is not completely invisible, but is based on a certain recognition probability, and its main role is to evade the enemy's satellite detection, radar scanning and other technical reconnaissance, and at the same time, it can also greatly avoid the locking of tracking weapons. The actual test is to detect the stealth effect of the phantom mecha, whether it can really meet the design standards, whether it can evade the locking of various reconnaissance techniques, and whether it can avoid the tracking of lock-on weapons.

The stealth ability test is also divided into ground test and space test in the actual test, and the ground test is much simpler than the space test, as long as it can achieve 80% of the stealth effect, the phantom's stealth ability can be considered a success.

Busy days always seem to go by exceptionally, and in the blink of an eye, the day passes.

As the days passed, the various tests of the Phantom Mecha were carried out and completed in an orderly manner.

On the seventh day of the restart test, the Phantom Mecha began to conduct a critical stealth ability test, which lasted for five consecutive days before finally ending. In the past five days, Fang Shi and his senior brother and sister did not walk out of the No. 1 experimental area until about ten o'clock in the evening almost every day and returned to their respective residences, which was quite hard, but the hard work and hard work gave them extremely good rewards, and from the final data obtained from the continuous testing, they got that the stealth effect of the phantom mecha reached 95%, which was considered to have reached the standard of their design, and it was a quite satisfactory result.

After the stealth ability test, there are three more routine tests, the difficulty of the test is not great, and for this kind of routine test, Ye Zhiqiu and Fang Shi and other members of the phantom working group still have confidence, if nothing else, the ground test of the phantom mecha should be relatively successfully completed.

In the following days, the Phantom Working Group successfully completed the last three tests. All three tests met the booked criteria, so that all the items of the entire ground test basically met the booked criteria, and the next stage of space testing can be applied. (To be continued......)
