Qian Wu was very reluctant to go to Qianzi Mining to check, and after thinking about it again and again, he was not embarrassed to call Zheng Jun to arrange for the mine to receive him, and came to the front of the office building by himself, thinking back to the past, he couldn't help but sigh, shook his head, and walked to the entrance of the crystal vein alone, looking around at the left and right no one jumped into the air duct, and the black screen stood there quietly, and the traces left by the explosion were still shocking.

"This is really not a good thing! I knew that it took eight lifetimes of effort to find this place!", Qian Wu came to the stone niche, and half of the palm print in the upper right corner was clearly visible,

"Li Jun, this kid doesn't know what's going on, so he feels that he has the right temper with Lao Tzu and has accidents one after another, and he finally sobered up but he doesn't seem to know Lao Tzu at all, alas!" , Saying that Qian Wu sat down slowly, took out the wine bottle and drank it and fell asleep leaning on the stone niche, vaguely shaking behind him, as if there were thousands of calls tearing his heart, Qian Wu's breath in his chest suddenly became manic, and after waking up, he meditated cross-legged on the spot, his heart condensed a line, and gradually calmed down his breath after a long time, but he heard the sound of someone sucking water faintly from the depths of the niche wall, and felt strange, listened to it, but there was no sound of it, shook his head vigorously, looked at the wine bottle next to his feet, and secretly muttered whether he had drunk too much wine, and was about to kick this harmful wine bottle, but heard a crisp sound of glass breaking, and then looked at the wine bottle, which was obviously still standing here,

"Lying grass, is this an illusion?", suddenly the surrounding aura fluctuated, and the light in the niche flowed up rapidly, Qian Wu was shocked, but he could only watch the colorful streamer flow upward, fortunately it stopped quickly, Qian Wu immediately left the secret room, looking around, but did not find anything unusual, did not dare to act rashly, and went back to the sect to report to Wang Cheng.

Zheng Miaoyan and Tanaka Crane came to the secret laboratory of the military department, which was originally a nuclear radiation contaminated area after World War II, Okamura Osa stood straight at the gate of a dilapidated courtyard, with excitement on his face that could not be concealed,

"Teacher, Mr. Zheng, please follow me!", the small courtyard is not big, and the foyer is not specially repaired, after entering the room, Okamura opened the small door of the toilet and saw a diagonal downward passage, and after walking about a few dozen meters, it suddenly opened up, and the hall with facilities like an alien base, the three of them took the elevator all the way to the -42nd floor, Okamura respectfully handed the two protective suits, and introduced,

"Now the military's secret experiments are here, and there is no vigilance and protection deployment on the surface to prevent satellite and drone shooting, but this does not mean that there is no vigilance, there is only one passage here, and the passage I walked through just now has 32 biometric authentication facilities, if it cannot be detected by the system, it will be directly incinerated at high temperatures, this", Okamura looked at Zheng Miao,

"Don't talk about the rest, please look at the two of you!", Zheng Miaoyan looked forward, this room is quite narrow and long, and there is no end in sight, there is a blue bulge every 4 or 5 meters on the walls on both sides, and there is a control room similar to a submarine rescue pod in front of the room, Tanaka Crane took a closer look and nodded,

"I didn't expect you guys to come this far!", Okamura sneered.

"The teacher has won the award, these achievements are the teacher's credit!please!", Tanaka Tsuruchi sat on the main control seat from the top of the front, only to see that the console facilities are very simple, next to a putter on the right is simply marked 8, 80, 800 three step options, there is a charge indicator window in the center, two buttons below, one is marked SEMI, and the other is marked AUTO.

Tanaka Tsuru asked,

"Okay-mura-kun, is this designed according to the railgun?", Okamura Osa replied excitedly,

"Teacher, this is not perfect, but it is indeed designed with the electromagnetic railgun as the template, and the initial experimental effect is very stable, today I invite the teacher to personally correct it!", Tanaka Crane's eyes emitted a strange brilliance,

"Our big RB empire is finally going to rise again, Gangmura-kun, is it okay?",

"Of course, please!", Tanaka Crane put his right hand on the right pusher, the lights in the room suddenly went out, Tanaka Crane firmly pushed the pusher to the 8 position, the narrow room passage in front of him began to lift upward, and stopped at an angle of about 30 degrees, and a faint light appeared in the distance, and a screen descended above the console, showing the image at the end of the room, and a pair of blue bumps on the wall closest to the console began to hum, at this time Zheng Miaoyan realized that this room turned out to be a huge cannon barrel!

Tanaka Tsuru was about to press the launch button when Gangmura stopped him,

"Teacher, you underestimate the Imperial Army, please continue!" Tanaka Tsuru nodded with satisfaction, and sent the putter to the 80 position, at this moment the buzz in the room became a roar, and the energy bar on the middle platform reached the level of level 3, and after the button was triggered, a huge thick black iron block rose from below, and when it reached the blue bulge level, it flew out with a buzz, and when it reached the third blue bulge position, a loud bang broke out of a thick fog, followed by a violent vibration, and the iron block tracked on the screen dragged a huge flame out of the atmosphere, and disappeared in an instant.

Zheng Miao's officials were completely stunned,

"This, this, what is this?", Tanaka Tsuru smiled,

"Mr. Zheng, this is the tomorrow of our empire, a railgun with 80 times the speed of sound!", Zheng Miao couldn't talk, and Gangmura Dazuo said on the side,

"At the beginning, it was a sound barrier, and this 80 times the speed of sound means that it has far exceeded the third cosmic speed, and it can achieve ultra-long-range outer space strikes!!", Zheng Miaoyan felt a little disgusted, covered his chest and asked,

"Third cosmic speed?!", Tanaka Tsuru didn't pay attention to him, looked at Gangcun and asked,

"This 800 should mean sub-light speed, right?", Gangmura nodded firmly, Tanaka Tsuru said,

"So?",

"Please, teacher!", Tanaka Crane felt his heart beating rapidly, his right hand weighed a thousand pounds, and pushed the gear lever with difficulty, and the progress of the central control energy slowly reached the fourth and fifth levels, and the buzzing sound around it had made it difficult to breathe, and when the energy progress display gradually reached the sixth level, there was a sudden violent tearing of space, and several people temporarily lost their sight and hearing, lost their heartbeat and breathing, suddenly!

The surroundings quieted down, everything returned to normal, Zheng Miao opened his eyes, and everything in front of him disappeared, leaving only a big hole that went straight to the outside world, and then collapsed with a bang.

Gangcun did not panic, and took out the walkie-talkie on the side,

"Report, report, the 59th trial failed!".
