Compared with large war machines such as J-K fighter jets, the research on hand grenades is relatively simple. Although grenades are different from landmines, their properties and principles are interoperable. Landmines are buried underground and require people to step on them to cause an explosion.

The grenade needs to be struck, and then it will explode after being thrown to the ground. The only difference is that the landmine is not as convenient to use as the grenade. The landmine is buried underground. If no one steps on it, it will not explode.

take effect.

Wang Yusong has always obeyed Tang Zheng's orders. He will do whatever the leader says. Tang Zheng said that he would do his best to research and make grenades. Naturally, he would not refute and do not study. However, before agreeing, Wang Yusong still had one thing.

The matter needs to be reported to Tang Zheng.

"Reporting to the leader, a few days ago, we not only developed landmines. We also developed laser guns. Laser guns that use aura are much more powerful than laser guns that use ions." Wang Yusong straightened his back and reported.

Laser gun? It’s a high-tech product. I didn’t expect Wang Yusong and the others to be able to develop the tower. The earth laser is a patent right of China. Looking at the entire earth, only Chinese scientists have invented laser technology and used it.

On to the weapons of war.

Wang Yusong was able to research the ion laser gun using aura methods. It must be said that he had an absolutely amazing talent in researching war weapons. The successful research on the laser gun made Tang Zheng more confident about the upcoming difficulties.

"Yusong, you have never let me down. If the medical school survives this crisis, you and the team you lead will be the absolute heroes. No matter what your requirements are, I will definitely satisfy you." Tang Zheng patted lightly.

Wang Yusong said slowly with a look of joy on his shoulders.

Tang Zheng went to a special area and took the laser gun to a place near Qinglong Peak to test its power. You won't know if you don't try it, but you will be shocked if you try it. The power of the aura laser gun can actually be compared to the annihilation-k aura bullet attack.

Undoubtedly this was an unexpected surprise.

The recoil of the spiritual energy laser gun is much smaller than that on the earth. The method of use is also simple. There are two methods. The first is to use the spiritual energy gathering array to absorb, gather and compress the spiritual energy of heaven and earth, wait until the spiritual energy is compressed into spiritual energy bullets, and use the shoulder to push it

Just hold the barrel of the gun and pull the trigger.

The second method is to use one's own true energy as spiritual energy bullets.

The two methods can be used interchangeably, so there is no need to worry about the lack of spiritual energy bullets. Of course, the bullet attack of the laser gun is not only the spiritual energy bullet. There is also another attack, which is the beam attack.

Beam attacks require much more spiritual energy and real energy than spiritual energy bullets. Naturally, they are more powerful than spiritual energy bullets.

Wang Yusong's face was full of pride and he said with a smile: "Chief, the power of the laser gun has two attack methods. It's great, in fact, I think so too. The two attack modes can be switched to each other, so there is no need to worry about insufficient bullets."

"Well, that's it. Yusong, what wishes or requirements do you have? Say it, and I will help you realize it when the medical school completely overcomes the current difficulties." The research team led by Wang Yusong has dedicated its research work to the medical school.

, because of the appointment by the state, they have never asked for anything.

But are they really willing to live like this for the rest of their lives? Don't they have any unfulfilled wishes? Having said that, Wang Yusong and the others are really willing to live like this for the rest of their lives. The mission of a soldier is to absolutely obey the arrangements of his superiors. Tang Zheng did not let them leave.

I will carry out my research operations to the end for Tang Zheng in this life.

However, they do have wishes. They have been in the world of cultivation for a long time, and they also miss some of their relatives and friends on Earth. Of course, those who miss their relatives are only a minority in this research team.

Because most of the researchers are orphans and have no relatives. A small number of people worship Tang Zheng, and because they have older brothers or younger brothers at home, when the country calls them, they resolutely obey the country's call and follow Tang Zheng.

Zheng came to the world of cultivation.

Tang Zheng's straightforward words gave Wang Yusong some confidence, and he said slowly: "Chief, most of the brothers below are orphans. And a small number of people because they have older brothers and younger brothers at home and worship the chief, they choose

Responding to the call of the country. However, we have been in the world of cultivation for some time."

Wang Yusong paused here and then continued: "They are beginning to feel homesick. If possible, I hope the chief will wait for the medical staff to overcome the current predicament and let them go home."

Going home is such an ordinary and sacred word, but for Wang Yusong and the others, it has now become a luxury wish.

The pain of leaving home is caused by the longing for relatives and friends. Tang Zheng has experienced this personally, so he understands Wang Yusong and the others very well.

"No problem. Once the current predicament is over, I will arrange for you to return to Earth." Tang Zheng promised.

Wang Yusong looked happy and said loudly and forcefully: "Thank you, chief."

The total number of laser guns is not that many, only about thirty. Compared with the number of landmines, although the number of laser guns is small, its effect is definitely much better than that of landmines.

Before Tang Zheng left, Zheng Xin hesitated, as if he had something to say. However, due to face, he never spoke. Now that Tang Zheng was about to leave the special area, if he didn't speak, it would be too late.

When Tang Zheng walked to the door, Zheng Xin suddenly shouted: "Tang Zheng, wait..."

He turned around and looked at Zheng Xin doubtfully, and said slowly: "Is there anything else?"

Zheng Xin and Wang Yusong lived together day and night. Zheng Xin'er heard and heard a lot about the strange things on the earth, as well as high-tech products. She also yearned for it very much and wanted to go to the earth. Now there is a rare opportunity. If Zheng Xin misses it,

, he will regret it for the rest of his life.

In order not to leave regrets and regrets, Zheng Xin finally said: "Well...this...can I go to the earth with Yusong and the others? I am very interested in scientific and technological civilization. I think if I go to the earth, in the future

We will definitely be able to invent and create more things. This will also be beneficial to the development of medicine."

Zheng Xin's request made Tang Zheng a little stunned. He didn't expect that technological civilization would be so charming that Zheng Xin, an old monster, would be obsessed with it. However, what Zheng Xin said was very reasonable. Zheng Xinruo went to Earth

, he can definitely learn from the products of technological civilization on earth.

If we bring the scientific and technological civilization learned on Earth to the world of cultivation, it will definitely play a significant role in the future development of the medical sect. So Tang Zheng didn't even think about it and directly agreed: "No problem, you are also for the development of the medical sect.

For your own sake.”

Leaving the special area, Tang Zheng locked himself in the room. No matter who knocked on the door, he did not open the door and disappeared. Even when his wife and children came, he did not open the door. Tang Zheng was strange. It makes everyone feel very serious.

They didn't know what the specific matter was. They kept going to Pixiu to ask again, what exactly happened when they went to Qianzhou? Why did Tang Zheng become like this when he came back? Tang Zheng had already told Pixiu Zhong, telling him He should not tell anyone about the situation that the medical community is about to face.

Pixiu Zhong didn't get Tang Zheng's permission, and he didn't dare to tell what happened in Qianzhou.

"Sisters-in-law, I really don't know why Brother Zheng is like this. Stop asking me, no matter what you say, I still don't know. Brother Zheng may be at the juncture of breakthrough. Otherwise, how could he Maybe I won’t meet my sisters-in-law?”

Pai Xiu Zhong said in the last sentence that Brother Zheng might be practicing, which made Chu Ruyue and the other girls leave with doubtful expressions. Is Tang Zheng really making breakthroughs as Pai Xiu Zhong said? Tang Zheng is not breaking through the bottleneck, he is meditating. Think about how to handle the situation in front of the medical department and how to tell everyone about it.

Tianmen and Gulas' forces belong to the realm of cultivation. If they really fight hard, Tang Zheng, who has many war weapons, will not be afraid of them at all. However, what makes him afraid is the Sancha Gang of the pseudo-immortal world.

Tang Zheng didn't know the specific situation of the pseudo-immortal world at all. The general situation was told to him by Wang Qiliang. Facing the unknown enemy, Tang Zheng had to be more cautious. Otherwise, he would fall into a situation that would never be recovered.

After calming down, Tang Zheng thought about many possibilities. However, there was no possibility to avoid the disaster. The most serious case was that he himself died and the medical school ceased to exist. The lightest case was that he and his family survived. , the medical school no longer exists.

No matter which outcome it was, it was not the outcome Tang Zheng wanted.

"What should I do? How can I survive this calamity? If that day really comes, how should I explain it to my family, lovers, friends, brothers, and many medical disciples? Wait, I can tell the king Qi asked about the Sancha Gang. If you know yourself and the enemy, you will be victorious in any battle. As long as I understand the situation of the Sancha Gang, even if they are strong men in the pseudo-immortal world and are suppressed by heaven in the world of cultivation, I will be able to kill them."

Just do what you think of. Tang Zheng took out his communication artifact and dialed Wang Qiliang's divine number.

After answering the phone, Wang Qiliang said in a cheerful mood: "Brother Tang, you are so leisurely and elegant, please give me a call."

"Brother, brother, I don't go to the Three Treasures Palace for anything. I need to ask you something." Tang Zheng said straight to the point.

Tang Zheng gave Wang Qiliang the Life Soul God Grass, and Wang Qiliang used the Life Soul God Grass to save his son's life. Wang Qiliang was so sincere to Tang Zheng that he regarded Tang Zheng as his brother. Tang Zheng's tone was so solemn. , he knew that his brother was probably in trouble.

"Are you so polite to me? Just tell me everything." Wang Qiliang said cheerfully.
