Lu Yifan returned to the room, opened his arms and lay on the bed, his head buzzing.

If he goes on the mission himself, it would be great if there weren't so many messy things at home, then he could go with peace of mind.

But now...

After thinking for a while, Lu Yifan was so tired that he fell asleep.

the next day.

Shen Youran got up and went straight to the army to report. Not long after he arrived there, Bai Lishuang and Qin Ruxue came.

"How was your rest these past two days?"

Bai Lishuang came over and put her arm around Shen Youran's shoulders. "Ruxue has been researching the formula these past two days. The leader should call you over today. How is your research going?"

"That's fine. I wrote a recipe last night and plan to give it a try." Shen Youran did not hide it from Bai Lishuang. Qin Ruxue walked over from a distance and said, "Take a look at mine first. I still feel like I can't quite understand the recipe here."

Shen Youran took a quick look at the formula and found that there were indeed some problems. She took out a pen from her pocket, and the two of them squatted at the edge of the training ground and began to study the formula of the explosives.

"You should do this..."

Shen Youran was talking and Qin Ruxue was listening attentively. The two of them were so absorbed in the conversation that they didn't even notice Lu Zheng approaching from a distance.

Lu Zheng did not disturb them, but came to Bai Lishuang and asked, "Are they studying the formula?"

"yes."

Bai Lishuang looked helpless, "I was thinking we could be together, so I talked about training, but I didn't expect them to just squat and not move."

Lu Zheng did not disturb them. He squatted until their feet were numb and he had almost finished studying the formula before he got up from the ground.

“Finally done!”

Qin Ruxue breathed a sigh of relief. "I was wondering what went wrong last night. I didn't expect it to be the same problem as last time. Why can't I remember it?"

She has read so many books and done so much research, why is it still like this?

"Don't worry. In fact, it would be better if you change your way of thinking." After Shen Youran finished speaking, he briefly talked to him about changing his way of thinking. Qin Ruxue suddenly realized, "Yes, then I will use this way of thinking to consider this problem in the future."

When the two of them finished talking, they looked up and saw Lu Yifan standing in the distance.

"Lu Tuan."

Qin Ruxue called out first, then walked over quickly, "Are you here to report to us about your study progress this time?"

Lu Yifan nodded.

Shen Youran also came over, "Let's go, we'll come back after we finish reporting."

The three of them went to the commander's office together.

Commander Su and several other leaders were all here. After seeing Shen Youran and Qin Ruxue come in, they asked them to sit down first.

"Comrades, we want to know the results of your study this time, to see if you have learned anything?" Commander Su spoke, Shen Youran and Qin Ruxue looked at each other, then stood up one by one to report the situation.

In addition to talking about their studies, they also talked about their research on the formula.

"Then let's go to the training ground and try it?"

There were two people in their army who were researching explosives before, but during a mission, something went wrong while they were defusing a bomb, so there was no one left.

But there are special venues where you can try out the power of bombs.

"Then prepare the materials and we will report to the leaders right away."

Commander Su made the arrangements, and soon they arrived at the testing site.

Shen Youran and Qin Ruxue have already made explosives for two people according to their recipe.

"Come one by one. Comrade Qin, try the power of your explosives first." Commander Su spoke first. Qin Ruxue stepped forward and, according to the instructions, threw the explosives in her hand into the iron bucket in front.

She counted a few seconds silently and then quickly retreated. Commander Su and a group of leaders also retreated to the back.

"Bang!"

With a loud bang, the barrels were blew up by the explosives, but they did not fly very high, which showed that the power of the explosives was just average.

However, the explosives were better than those made by the person who had previously researched explosives in their army, so he still received praise from his leader.

Soon it was Shen Youran's turn.

Lu Zheng was also watching Shen Youran from a distance. He stood at a distance and threw the explosives in his hand into the iron barrel, then quickly retreated.

This time the voice was louder than Qin Ruxue's.

The iron barrel flew more than ten meters high, and then fell down, causing the surrounding ground to crack a lot. Many people in the army also felt the ground shaking.

When Commander Su saw this, he stared.

The other few people also found it hard to believe.

Qin Ruxue showed an expression of admiration on her face. Shen Youran had performed very well in the study class, and she didn't expect him to improve so quickly.

"Comrade Shen, I think your formula is very good. Can you increase or decrease the dosage according to the formula to make the power of the explosive a little bit smaller?" Commander Su was very excited. If Shen Youran's formula could really be used, it would be a great contribution to the army.

So he wanted to ask clearly.

"I can demonstrate it to the division commander on the spot, increase or decrease the dosage, and see how powerful it is."

Shen Youran had been researching this recipe for a long time, but he didn't dare to reveal it before because he would definitely arouse suspicion.

Since he has never learned it, how could he do this?

So it has been kept in the space and the recipe has never been perfected.

Later I attended a study class and only perfected it last night, then copied it again.

She thought it was no problem, and that increasing or decreasing the dosage would make the bomb less powerful.

Shen Youran demonstrated it again on the spot. Every time the dosage was adjusted, the power of the explosive would be reduced by half. In the end, it could be precisely controlled.

“Bang!”

“Pah!”

Commander Su and the other leaders all applauded. Lu Zheng looked at Shen Youran's bright smiling face, his heart pounding.

He had lived for more than twenty years and was almost thirty years old, but he had never felt his heart beating so fast.

It's a throbbing sensation.

Seeing the girl he likes becoming more and more outstanding, he also feels proud of her.

Qin Ruxue stood aside, looking at Shen Youran who was smiling brightly, and she really felt like she had met another Bai Lishuang.

In addition to this feeling, she also admired Shen Youran and wanted to learn from her. She wanted to research some explosives in the future and make contributions to the country.

"Comrade Shen is really amazing. It seems that this study class was not in vain. I heard that you only learned some basic knowledge, but you were able to expand it yourself."

"It's a testament to your intelligence."

"I will submit your formula for this explosive as soon as possible. Your formula is very useful to the country, and you will be rewarded generously!" Commander Su's heart beat faster. He thought that Shen Youran and Qin Ruxue would be able to research ordinary explosives at most after their trip. He didn't expect Shen Youran's performance to be so perfect.
