"Let's go take a look together." Liu Chi let go of Ye Yuxin's hand and ran down with Zhang Lao heroically.

Two hours later.

"Mr. Zhang, Mr. Su, Mr. Liu, the problem has been found."

"What's the problem?" Old Su hurriedly put his brain in.

"There's something wrong with the suspension system. One of the suspensions is broken. It should have been torn off by the strong recoil when the trapezoid fell during the test just now."

"The third heating device on the left was directly scrapped, and the oxygen supply system was directly destroyed, thus stopping the engine from working." Li Hui crawled out of the tank.

"Let me take a look." Old Su pushed Li Hui away and went forward to check it himself.

"It doesn't make sense. When we used the original engine, it wouldn't break even at three meters, let alone one." Someone nearby questioned.

"But, is the suspension really broken now?"

"Well......"

“Will there be any problem with this suspension?”

"Impossible. How can we not consider the quality of the equipment?"

"Take it apart first and take a look. Then you'll know after you take it back for testing."

"Yes, yes, take it out first."

Mr. Su looked at the hanging and fallen structure for a long time, wondering why it broke, and he was faced with the same huge doubt.

A shoddy product?

Impossible.

So what's the problem?

"Mr. Su, take the things out and have a look first."

"Okay, let's take a look first." Old Su looked for a long time but couldn't find any problem.

"......"

After a lot of effort, the engine suspension system was finally removed.

While everyone was discussing, Liu Chi picked up a broken light steel structure and looked at it carefully.

......

"Maybe..." Liu Chi said thoughtfully, "Maybe I know the cause of this accident."

Liu Chi was holding a round piece of synthetic light steel in his hand. It could be clearly seen that starting from the fracture, the round piece of light steel was surrounded by a layer of rough reddish-brown particles.

This is obviously the most intuitive manifestation of metal fatigue. Its internal structure has been destroyed by external forces and its strength has been severely reduced.

"The reason for the metal fatigue is probably that it was broken by explosive force under high temperature conditions." Liu Chi said.

"High temperature?" Old Su asked a little puzzled.

"Mr. Su, don't forget that the heating device is as high as 550 degrees, and this suspension just relies on the heating device."
