Liu Zhengjing had no choice, when he woke up, he was in a closed room, the room didn't even have a window, the door was metal, the walls were metal, Liu Zhengjing smashed it with his fist, and the dull voice told him that the metal wall was probably at least dozens of centimeters thick.

Even a martial artist can't get out.

Therefore, Liu Zhengzheng's body was not restrained, and he also died of the mind of escaping from prison.

Instead, he wandered around the room, where there was only a table with some paper materials on it.

Liu Zhengjing flipped through it and found that it was all some design drawings, and he was a little shocked when he looked closely.

The content of these materials turned out to be weapons, including bombs, firearms, pulse guns, and formations.

Liu Zhengjing flipped through it for a long time, until a small window appeared on the ceiling, and some food hung down before he came back to his senses from those materials.

It just so happened that Liu Zhengjing was a little hungry, and he didn't worry about poisoning, after all, now people are knives and I am fish and meat, so there is no need to poison the food.

After gobbling up for a while, Liu Zhengjing returned to the table and looked at the information on those weapons.

The old man will not lock himself in this room for no reason, these weapon design materials that are considered top secret outside are impossible to forget to clean up, with the intention of being at ease when he comes, Liu Zhengzheng buried his head and looked at it.

……

Hua Wuxiang's pretty face was frosty, and she came out of the Hundred Flowers Club and walked towards the north gate angrily.

Since ancient times, only the West Gate of Pingyang Town has a road to the outside world, and the other three gates are facing a steep circle of Gu (Daigu landform), as if they are just decorations.

Directly opposite the north gate, there is a five-meter-wide cave on the mountain, and the cave is dark and blocked by a taller number, and the entrance of the cave cannot be seen from any direction.

Hua Wushang walked into the cave with a familiar car, walked dozens of steps and turned a corner, and a heavy metal door appeared in front of him.

It's a hidden underground base.

Hua Wushang looked up at an inconspicuous small hole in the top of the door, and there was a camera in the small hole.

"Open the door!" Hua Wushang's tone is not good.

"Please wait a minute, and let me know right away." I don't know where a man's polite electronic voice came from.

In the duty room behind the metal door, a young man in a white lab coat trotted all the way through the bright corridor to an office.

The white-bearded and white-haired porcelain old man sat on a soft slump and pretended to sleep.

The young man said cautiously: "Ancestor, the boss of the Hundred Flowers will ask to see you." ”

The old man didn't open his eyes, and said softly, "Let her get away, this is not the place where she said to come." ”

The young man's face was embarrassed.

The old man glanced at him lightly, "Don't be afraid of her, just tell her to let go if she has a fart, and go quickly if there is nothing to do." ”

It was clear that the old man did not want to see the flowers. Waiting for the young man to trot away, the old man muttered, "The door is full of vixens, you know how good you are with a good child, and what a good child the third watch should be......"

The young man went for less than a minute, and then hurriedly ran in, "President Hua left a message, it's okay to take that kid out of anger, and you can't hurt your life." ”

The old man suddenly opened his cloudy eyes, and a flash of anger flashed, "Presumptuous! ”

After that, he got up and walked out angrily, walking like the wind, where there was an old man.

The heavy iron gate slowly rose, and there was only an empty cave outside the door, where there was still the shadow of flowers without clothes.

"Unruly little Nizi, count you as a fast runner." The old man turned slowly, looking old again, and the crutches clattered in the silent corridor.

The old man returned to the office, and just lay down, when the young man hurriedly came in again, "Old ancestor, Zheng Zatang is here." ”

The old man opened his eyes, and his face was full of boredom, "Let him in." ”

As soon as he finished speaking, a tall figure had already stepped into the office.

Zheng Da bowed and saluted, "Zheng Da pays a visit to the sixth uncle." ”

The old man sat up slightly and hummed softly, "You are not guarding the ancestral hall, what are you doing in the Tiangong Pavilion?" ”

Zheng Da said calmly: "Come for the two people you arrested today." ”

The old man rolled his eyes, "What, you also have to come and tell the old man not to hurt that kid's life?" ”

Zheng Da smiled, "Don't dare, Senior Sister Hua is unscrupulous, Sixth Uncle Ancestor must not be angry, I am here for another person." ”

The old man was puzzled: "Isn't that the person who talks about Great Qin, if you die, you will die, and you will be used to run." ”

Zheng Da replied: "This person is different, and it may be beneficial to my Hongmeng in the future." ”

"Well, let's let it go." The old man nodded to the young man who was waiting, and the young man walked away quickly.

Seeing that Zheng Da hadn't left yet, the old man asked, "Is there anything else?" ”

Zheng Da pondered for a moment, "Liu Zhengjing...... It has not yet joined the EU. ”

"Didn't Xiao Yong take him as an apprentice?"

"Accepting apprentices is accepting apprentices, getting started is getting started, and the rules can't be broken." Zheng Da said.

The old man stood up suddenly, blew his beard and glared, "Rules, rules, why didn't you mention the rules when Liu Sangen left twenty years ago?" ”

Zheng Da bowed his head slightly, but did not speak, and his attitude was still insistent.

The old man lost his temper, sat back down, and softened his tone, "I also know that you are not easy, don't worry, I am a lot old, and I won't come nonsense." After saying that, he waved his hand.

Zheng Da arched his hand and turned to leave.

The old man sat for a moment, got up slowly, walked out of the office, and made a single palm on a wall, on which a palm pattern lit up, and then the wall parted to the sides, revealing an elevator.

The elevator slowly descended for nearly 100 meters, opened again, and the outside of the elevator became a large space, and I don't know how many researchers in white coats were busy walking.

Who would have thought that there would be such a large base under the mountains of Pingyang Town.

The old man walked slowly, and from time to time someone greeted him, most of them were called "old ancestor", and there were also people who called him "hall master", "pavilion master" and "master".

The old man walked to a metal door, put his hand on it, and the metal door opened, revealing a small secret room.

In the secret room, Liu Zhengjing raised his head and watched the old man step in, stood up and waited quietly.

The old man stepped in and asked expressionlessly, "Do you understand?" ”

Liu Zhengjing thought about it and said honestly, "I don't understand." ”

"Do you know what these materials are for?"

"It's like researching weapons against powerful warriors."

"Any ideas?"

"No idea."

"Oh, I'll come back when you have an idea." The old man was about to leave.

"Wait." Liu Zhengjing hurriedly called out to the old man, although he didn't know what the old man wanted to do, but he understood the old man's words, as long as he had no ideas for a day, he couldn't go out for a day.

"I actually have a little bit of an opinion."

The old man looked at Liu Zhengjing and motioned for Liu Zhengjing to continue.

"I've probably seen dozens of weapons here, most of them are pursuing the power of a single weapon in order to maximize damage, and the target should be a martial artist or a martial artist above the realm of martial artist."

Seeing that the old man was noncommittal, Liu Zhengjing continued, "Martial artists at the realm of martial artists and above already have a sense of crisis, whether it is a bomb or a stolen bomb within range, either the instant lethality is not enough, or it is difficult to hit or completely cover. ”

"At present, the individual lethality of these weapons has reached a bottleneck, and no matter how strong they are, there are higher requirements for volume and detonation methods."

Liu Zhengjing's words are not nonsense, since he came to this world and found that he was a waste of firewood, Liu Zhengjing has studied powerful weapons that can compete with warriors and warlocks, and after research, he found that the scientific and technological weapons in this world are still very backward.

This is understandable, for a civilization that relies on Zhenqi and warlocks to develop, there will always be a lame in terms of technology.

Liu Zhengjing in his previous life was considered to have been to the battlefield, and as a diligent and studious reporter, he also studied all kinds of battlefield weapons, comparing the two worlds, if there were no high-end martial artists and warlocks in Daqin, he would be beaten by Huaxia in his previous life.

"You say that if you know these things with a long brain, you don't have any useful insights?" The old man was not satisfied.

"I have an idea called 'cluster bomb', which uses a mother bomb to carry dozens or hundreds of bullets, and detonates the mother bomb by triggering or setting a fuse, and then covering the bullet within a certain range in an instant."

"What's the difference between your thinking and throwing dozens of bombs together?" The old man was not optimistic.

Liu Zhengjing patiently explained: "Naturally, you can't see the difference by throwing it by people, if you rely on machinery or planes to drop it, the killing efficiency within the range is very high, and it is not easy for even a martial artist in the martial arts realm to dodge." ”

The old man's palm gently scrubbed the crutch, his eyes became brighter and brighter, he knew weapons, the lethality of bombs and bombs when they exploded densely in the range was not 1+1=2, and when the number of bombs in the range reached a certain number, the lethality would increase geometrically.

After a long time, the old man said to a camera overhead: "Hear it, immediately notify the Great Wilderness Branch and start researching the experiment."

At the other end of the camera, more than a dozen researchers sat in a small conference room, and they discussed it instantly.

"According to the information in the cabinet, there were similar experiments many years ago, and the difficulty of detonation and design were very difficult."

"With our technology now, we can try it."

……

Liu Zhengjing breathed a sigh of relief, he was really worried that there was already such a thing as cluster bombs in this world, after all, it was not difficult to think of.

This thing has existed in previous lives, and it has been banned internationally, because the killing area is too large, and it is very unkind.

"Do you have any other ideas?" The old man looked at Liu Zhengzheng with blazing eyes.

"Yes." Liu Zhengjing thought about it and nodded, "But, why should I say it." ”

The old man was stunned for a moment and smiled, "Do you know what this place is?" ”

"I don't know."

"This is the Tiangong Pavilion, the most important of the thirteen sects of the Hongmeng, all the weapons that can cause damage to the warriors and warlocks are tightly controlled, my Hongmeng can compete with Great Qin for thousands of years, and naturally there will be its own weapon research and development department."

"Tiangong Pavilion supplies the weapons of the entire Hongmeng, including combat weapons and magic weapons."

The old man said proudly, his eyebrows raised a lot.

"Oh."

"Huh?"

"What does it have to do with me?"

The old man was speechless, "You don't know that your father was the previous Tiangong Pavilion Master?" ”

Liu Zhengjing was taken aback, he guessed that Liu Sangen should not be an ordinary person in Pingyang Town, but he didn't expect it to be such an important department leader.

The old man sighed, "Your father owes me a lot of Tiangong Pavilion." ”
