My sister returns to a wealthy family, and her eight brothers spoil her with their lives.

Then Dong Zhiqiang took a model of a heavy tank from the model display area in the conference room.

"Everyone knows that this model was made by General Ye Yuan, but don't be deceived by the appearance of the model. He actually made it according to the 20:1 ratio of a heavy tank."

Donald Qin was puzzled.

"Boss, you are really good at this. Didn't you show us this crystal? Why did you bring out the model again?

Besides, the research conducted by our special forces department is different from the weapons research and development department led by Lao Ye. "

"Lao Qin, I told you that you are always so impatient. Zip your mouth shut and just watch carefully with your eyes."

Everyone saw Dong Zhiqiang stuffing the obsidian crystal into the battery compartment of the heavy tank.

As soon as the switch was pressed, the tracks of the heavy tank model started to move, and it started to move wildly on the circular conference table.

It also knows how to avoid obstacles such as tea cups, and can cleverly avoid the edge of a table.

"Oh my god! Leader, am I seeing right? This citrine is so amazing. Did you install a battery? Or is there some other energy source? Like solar energy?"

"Say it again, this is energy-rich obsidian crystal!" Dong Zhiqiang corrected loudly.

Qin Dong couldn't help but stand up, forgetting that he was in a meeting, and he quickly ran to Dong Zhiqiang.

It just so happened that the heavy tank ran back and forth a few times and returned to Dong Zhiqiang.

Dong Zhiqiang quickly grabbed the heavy tank model, pressed the switch, then took out the crystal and continued to show it to him.

"Are you optimistic, Lao Qin? Aren't you studying new energy sources for missile thrusters?

I think this Yao crystal is very suitable. You'd better develop a large number of substitutes, because there is only one Yao crystal, and it is too precious!"

Qin Dong caught Yao Jing and was so happy that he was dancing for joy. The bottleneck of half a year was suddenly broken today.

He heard Dong Zhiqiang say again, "Old Qin must be rigorous and keep it secret. We don't even tell other leaders and internal comrades of our base, just a few core members of your research office.

As far as I know, Yaojing has not appeared in the world yet."

Indeed, no country has yet found any ore with such huge energy.

"Leader, where did this Yao Jing come from? I was so excited just now that I forgot to ask."

Dong Zhiqiang: "Confidential! Don't ask questions that you shouldn't ask, and I just said this one and only one.

Our comrades have worked hard to get this Yaojing, you must be careful when researching it and don't waste it."

Dong Zhiqiang then talked about some taboos regarding Yao crystals, such as that they cannot be exposed to sunlight, and then he solemnly put the Yao crystals into a black metal box.

The meeting ended, and Qin Dong immediately returned to the special technology department's laboratory with the engineers, carrying the black metal box.

Xiao Xi and Ye Xingxian discussed in the castle in the sky for an entire night how to transform Ye Lingfeng.

It was not even seven in the morning when she and Ye Xingxian returned to the family reception building.

They were going to take their parents and brothers on vacation.

However, Xiaoxi and Fifth Brother's well-thought-out plan suddenly went wrong.

Because Xiaoxi saw the security guards she knew and came to their reception building.

"General Ye, General Liang, Major General Xiao Xi, and Minister Ye, the leader wants you to come over.

Also, I am sorry to tell you that our leaders said that your vacation has been cancelled. "

"Ah?! What happened?" Xiao Xi jumped up in surprise.

Is Dong Zhiqiang so incompetent? I just gave him a piece of obsidian crystal yesterday, and today I turned against him and refused to recognize him?

Mom and Dad’s rare two-day vacation was cancelled just like that!

So angry! She, her parents, and her fifth brother had no choice but to follow the guards to see what was going on.

Ye Aotian instructed his younger brothers to continue returning to the reception building and told them to stay calm.

He was also very curious. He didn't expect that his fifth brother was from the military region and was actually the director of the metaphysics department. You can just be the head of a mountain, why do you want to be the director of the metaphysics department?

But Ye Aotian was even more curious. What happened if his father and mother were asked to go?

By this time, Xiaoxi and the others had arrived at the small conference room.

Dong Zhiqiang and another half-bald man were seen sitting dejectedly in the conference room.

Dong Zhiqiang immediately jumped up from his seat when he saw Xiaoxi.

"Xiao Xi, Xiao Xi, come quickly, I have something urgent to talk to you about."

Xiao Xi resisted the urge to roll her eyes out of displeasure. After all, she was just an elementary school student, so she could just say whatever she wanted to say.

"Uncle Dong! You are so unkind. You clearly know that my parents are on vacation today. Our family is finally reunited, but you still want to cancel their vacation? Do you think this is appropriate?"

Ye Yuan immediately patted Xiao Xi's hand, "Xiao Xi, don't be rude to your leader. We soldiers are on standby at all times. How can we have any vacation?"

Because her father said so, Xiao Xi held back her unhappiness and looked at Dong Zhiqiang.

"Uncle Dong, please tell me what's going on?"

Dong Zhiqiang was extremely embarrassed, "The reason for canceling Lao Ye and Comrade Wanyi's vacation is mainly because we encountered a very difficult matter."

Xiaoxi was just about to talk about something difficult, why are you looking for me?

Dong Zhiqiang knew what Xiaoxi would say, so he blurted it out without any foreshadowing.

"Yaojing is missing! It was handed over to Lao Qin of the Special Technology Department yesterday afternoon, and then it was discovered that it was missing this morning! Xiao Xi is really embarrassed."

"Ah, Uncle Dong, it hasn't even passed twenty-four hours, why did it get lost?" If I had known so many things, I shouldn't have handed over this crystal, causing my parents' vacation to be cancelled.

Qin Dong on the side felt extremely ashamed, he wished he could bury his head lower than the table.

But now is not the time to feel ashamed, "I'm sorry everyone, I failed to live up to the important task assigned to me by the leader."

Xiao Xi waved her hand, "Uncle Qin, right? Instead of blaming yourself here, take us to your laboratory."

Qin Dong knew that Ye Yuan's daughter was a great one. She was still a major general. Even Ye Yuan's son was in the metaphysics department of the General Military Region.

The most important thing now is to check for the lost Yao crystal. Everyone here is from the military zone, so it is not against the rules to enter his research center.

So Qin Dong led everyone into the research room of the special department.

The security is currently very tight and the people inside cannot get out.

Xiao Xi learned that the laboratory brought together top military engineers and technicians, and their current main research focus was missile propulsion energy.

"Uncle Qin, can you tell me how Yaojing disappeared?"

“Yesterday, the engineers and I cut a small piece of obsidian and put the big piece in the most important safe.

Then we began to work on it without sleep or food, and a few of us only rested for two or three hours.

When I woke up this morning, I found that the piece of obsidian that was being cut had melted.

We thought the operation was improper and quickly went to get the big piece from the safe, only to find that the obsidian crystal in the black metal box was missing. "
