Huaguo, the capital, in an extremely secret underground research institute.

It was a late autumn night, but the lights in the institute were bright.

The space here is huge, like an underground town, and hundreds of thousands of people are working hard in it.

After all, if a country with a population of more than one billion people relies on such a research institute for all its science and technology, no one will believe it.

However, this is the truth, the nearly 1,000 people here are the backbone of science and technology in the whole country, and the equipment here is also the most advanced in the whole country.

Is there a giant crossbow with a range of 50,000 meters and can penetrate a three-meter-thick steel plate? No.

However, there is only one here.

It was the former number one master of Longxiang, Qin Tianyang, the iron-armed god of war, who risked his life and brought it out of the ghost valley frame.

Moreover, the most precious thing is not the giant crossbow itself, but its drawings.

But because a lot of materials can't be gathered, so the research institute can only use similar materials instead, although the power is reduced by about ten times, but this technology is used on sniper rifles, just imagine, if there is a team, each with a range of 5,000 meters, can penetrate 30 centimeters of steel plate sniper rifle, how terrible it would be?

Moreover, this range is the effective range.

There is no shortage of sharpshooters in the army, who can use a sniper rifle with an effective range of only a thousand meters to hit the enemy at a distance of 1,500 meters, and at that time, the bullets are even a little floating, and they will be affected by the wind resistance.

Therefore, if it is in the hands of a sharpshooter, such a sniper rifle may be able to snipe the enemy from a distance of 7,000 meters.

Of course, this is the ideal state, even if it is imitated, it is far from mass production, and there are only a few hundred in the whole of China, all of which are in the hands of the most elite soldiers.

In one of the institute's offices, Han Xing, the political commissar of Long Xiang, sorted out the latest documents.

Suddenly, a smart machine behind the door made a voice: "Chief, member of the Dark Blade Department of Long Xiang, Mei Xin asks to enter, whether to allow it." ”

"Let her in." Han Xing said without thinking, as if his mind was still on work.

"Please answer yes or no."

Han Xing was slightly stunned, and then laughed at herself, she almost forgot that this was in the research institute.

"Yes." Han Xing replied helplessly.

I saw that the metal door quickly opened from the middle, and I was greeted by a charming and tall figure.

"This machine is really brainless." Mei Xin walked in, and did not forget to despise the door.

Han Xing also smiled helplessly: "Although it is high-tech, I always feel that sometimes there is no general convenience." ”

"The safety performance is good, so let's use it." Mei Xin walked in, sat down opposite Han Xing casually, and then poured herself a cup of tea.

She has known Han Xing since she was a child, Han Xing was a few years older than her at that time, and the relationship between the two was also good, and even Han Xing's position as political commissar was promoted by Qiu Tianlong, so although Mei Xin is Han Xing's subordinate, when the two are alone, there is no need to stick to etiquette.

"Xiaoyu, look at this." Han Xing found a drawing in the drawer and handed it over.

Meixin's original name was Qiu Yu, but most people don't know it, so now Han Xing is the only one who uses the title of Xiaoyu.

took the drawings and looked at them: "Gold wire body armor? ”

Han Xing nodded: "Yes, the pair of golden cicada silk gloves you took out are very useful, not because of its material, but because of its special method, we can now mass-produce this kind of body armor, which is not only convenient and light to wear, but also has a bulletproof effect far beyond ordinary body armor." ”

"What about the cost?" Mei Xin asked in a deep voice.

Han Xing frowned, which showed that Mei Xin asked the key point in one sentence.

"The cost is slightly higher, only suitable for small batch production, and the cost of one piece is more than 100,000." Han Xing said.

It may not sound like a lot for the head of an army, but if you count it in the millions of soldiers, it's a super high cost.

"So, it's still not universal, right?" Mei Xin asked.

"There's no way around it." Han Xing said helplessly.

"What about the spirit fruit? Have you found a better way to use it? Mei Xin asked.

Speaking of returning the spirit fruit, Han Xing lowered his head, and there was still a trace of guilt in his expression.

Mei Xin is not stupid, when she saw Han Xing's expression, she realized something.

"The Three-Inch Daoist once told me that the value of a Spirit Fruit is more than ten times that of the peak master of the Lan Yuan level, it is the most precious item in this world, I hope you can make good use of it." The tone of the flattering heart became a little serious.

That was what she had earned with Qin Zheng's hard work, at the beginning, the consumption of flattery was so great, and her strength almost regressed, and she was not willing to use the Spirit Fruit, because she knew that the value of this kind of thing was something more precious than her life.

A spirit fruit, if diluted into medicine, can at least save dozens of soldiers who are in danger, which is the most magical elixir in the world.

"Xiaoyu, I don't want to lie to you, the spirit fruit was used by the dragon head Fang Yunjian, he wants to break through the realm and prepare to step into the red yuan level." Han Xing said in a deep voice.

"What did you say?" Mei Xin slapped the table and stood up.

Fang Yunjian, the contemporary dragon leader after Qiu Tianlong, his skill is at the Blue Yuan level Great Perfection, which is stronger than the ordinary half-step Red Yuan level, but he has cultivated all his life, and now at forty, it seems that he has reached a bottleneck.

If there is no adventure, it will be difficult to break through to the red yuan level in this life.

"Xiaoyu, don't get excited." Han Xing stood up and held her shoulder, "You should know that since Uncle Qiu's death, Long Xiang's overall strength has become weaker and weaker, without a real strong leader, Long Xiang's ability will be limited, Fang Yunjian is the leader of Long Xiang's dragon and is the number one master, if he uses the Spirit Fruit to break through to the Red Yuan level, it will be enough to reflect the value of the Spirit Fruit." ”

"Are you talking to me about values? The spirit fruit was enough to save the lives of dozens of soldiers, but he used it alone, what about the Hongyuan level? With the help of the Spirit Fruit this time, what will you use next time? My father has been a dragon leader all his life, and he has never used a little wealth in the organization, even the bow he left me is made from his own body, no matter how strong the dragon head is, if you only think about yourself, what is the difference between it and not having a dragon head? Mei Xin roared angrily.

Han Xing hurriedly covered her mouth: "Xiaoyu, I know you are angry, you may not understand certain things now, but there are some words, don't talk nonsense." ”

"Spread me." Mei Xin shook off Han Xing and pushed her back a few steps, "Sister, you have changed." ”

With that, Mei Xin turned around and strode outside.

"Ahem...... came Han Xing's violent coughing sound behind her, and then, a large amount of blood spurted out of her mouth.
