When Xiao Yu was about to hang up, Brother Chuan Xiao said hurriedly: "By the way, don't force Xu Mang."

"good!"

snap,

hang up.

Looking up at Director Guo, Xiao Yu opened his mouth, but found that he could no longer say anything. The words he had just organized came to his lips, but he did not have the courage to speak them out. Indeed, these contents were too shocking.

"What's wrong?"

"I think there's something wrong with your expression." Director Guo frowned, and an unwanted thought came to his mind. Could it be that he had also been told that Xu Mang, who arrived late and left early, and even disappeared, was his normal appearance?

"Ahem"

"Director Guo's next words may have an impact on your three views." Xiao Yu said: "My friend told me that Professor Xu is normal in his current working status. If he goes all out,

time, it shows that the matter has become very serious and we need to pay attention to it."

Hearing these words,

Director Guo was completely confused. Is this really the case?

The next day,

Xu Mang was still an hour and a half late. Fortunately, he was luckier this time. He didn't meet anyone and walked into his office safely.

"Almost!"

"It's time to start your performance!" Xu Mang stretched and then picked up the pen in his hand.

"The system understands!"

[Identified by the system, scramjet engine material exchange value: 1 (material)]

[Identified by the system, scramjet engine material exchange value: 1 (propulsion technology and aviation power)]

Um!

Very perfect!

When Xu Mang saw these two values, it meant that he had fully grasped the key points, but he still had to pay for the skill points and couldn't be bothered to think about it.

Pay!

"The system turns on beast mode!"

[Beast mode activated]

here we go,

The former Qilin Arm reappeared, but this time there was no audience. Only Xu Mang stayed in the locked office, struggling to solve the material problem at hand.

Swish, swish, swish,

The speed is still so fast.

for a long time,

By noon,

Xu Mang has completed 75%, but in order to catch up with the progress, Xu Mang decided not to have lunch, and tried to finish writing the remaining content within an hour, and then conduct experiments and end the work here after acceptance.

no way,

Time is running out, it’s almost the end of the month, and I still have a lot of things to deal with.

but,

Only half an hour passed,

Xu Mang completed all the content directly. Sure enough, hunger can make people unleash their unlimited potential, but at this moment, Xu Mang suddenly wasn't hungry anymore.

I slumped in my chair and thought for a long time,

Suddenly a thrill,

Then he stood up suddenly, took another stack of white paper, and wrote a few big words on the first page, "Structural layout and analysis of Mach 30 scramjet engine."

This is the last gift before leaving

Xu Mang looked at the big words on it and felt extremely emotional. Although it may not be possible to realize this kind of engine with current technology, it can be used as a technical reserve for the future in case it is actually used one day.

but,

Xu Mang checked through the system and found that the structural layout of the Mach 30 scramjet engine was exchanged for values, which almost cleared the skill values ​​of materials science, propulsion technology and aerodynamics.

If this little skill value can be exchanged for a hundred years of peace, I have to say
Chapter completed!
