The nuclear bomb was placed in a deep well, then the wellhead was covered with a layer of sand, and finally, an M1A2 tank was driven to the wellhead.

The seal is not particularly good, but it is sufficient.

"Time!"

Daniel Zhang immediately placed an electronic watch in front of Gao Yuan, and the time displayed on it was 42 minutes and 36 seconds remaining.

Looking at the number of the electronic watch, Yang Yi did not hesitate at all, and entered the number of forty-two minutes on the timer forty seconds.

Looking at the number entered by Yang Yi, Daniel Zhang hesitated, and then he couldn't help but say, "Will the time be too short?" Only three seconds? Or set it to an hour? In case the big snake man is late, in case the height is not enough, it is more appropriate to operate manually, and I will stay and prepare for manual detonation. ”

Yang Yi completed the input, he watched the numbers on the detonator begin to flash, showing that the timing had been completed, he breathed a sigh of relief, and said: "No, the time of the big snake people is accurate enough, there is no need to leave too much time, I am more worried that the mothership of the big snake people will leave again than not being able to arrive on time loudly." ”

Daniel Zhang said cautiously: "This...... Does it work? Your detonator is useless, what are you keeping it for? ”

Yang Yi shook his head, he put the detonator that had completed the time setting and could not be reversed into his pocket.

"Keep a souvenir."

Yang Yi clapped his hands and said, "Anyway, this is the first time that human beings have mastered the precise movement trajectory and time of the Great Snake People since the invasion of the Great Snake People, and it is also the first ambush operation carried out on this basis after the human race has obtained effective military intelligence for the first time since the invasion of the Great Snake People, so whether it is successful or not, we have carried out at least one ambush operation." ”

After finishing speaking, Yang Yi took the walkie-talkie and said calmly: "The water organization calls the black devil and reserves time for three seconds." ”

"Black Devil receive, three seconds."

Yang Yi put down the walkie-talkie, and Daniel Zhang couldn't help but say, "What can this tank be used for?" Explain to me, why do you have to cover the wellhead with a tank when you put it in the well? ”

Yang Yi looked up at the spaceship in the sky.

"The manhole cover plan originated from a reason that the Spark team led by Gao Yuan used to fool people during the expedition, but after I listened to it, I felt that this plan was very likely to be realized, because we finally accurately grasped the trajectory and time of the big snake people, and we also got two nuclear bombs, as well as a deep well that is not uncommon in the city."

Yang Yi looked at Daniel Zhang, and he still said calmly: "So, I decided to turn Gao Yuan's casual lie into reality." ”

Daniel Zhang scratched his head, and then he said very seriously: "I understand what you said, but what does the hood mean?" Why is it called the Manhole Cover Program? You can call it a tank plan, or you call it an artillery battle, why is it called a manhole cover plan? Oh oh oh, I see, this tank is like a manhole cover when it is put up, but why does Gao Yuan call it a manhole cover plan? ”

Xiao Ran frowned and said, "Brother Yong, don't interrupt, let's withdraw." ”

Gao Yuan waved his hand, and then he said to Daniel Zhang: "The reason why it is called the manhole cover plan, because this plan really originated from a manhole cover, in 2957, the United States people conducted an underground nuclear test, in a depth of 150 meters, 1.2 meters in diameter of a pothole, detonated a nuclear bomb, and then covered this deep well iron manhole cover rushed into the sky at a speed of nearly 70 kilometers per second, and disappeared since then, becoming the fastest flying object in human history." ”

Daniel Zhang nodded and said, "Oh, that's so, that's just a manhole cover?" And then what? ”

"Now the nuclear bomb we use has a yield of one million tons, the tank weighs 60 tons, maybe the speed is not as good as the manhole cover, but it may also exceed the manhole cover, the tank will be in the shock wave generated by the nuclear bomb and the violent friction of the air, into a metal jet, part of the vaporization, part of the scattering and disappearing, but according to calculations, it can still ensure that there are more than five tons of residual jet can reach a height of three thousand meters, well, the mother ship of the snake people hovers at an altitude of six thousand meters above the ground, and this altitude, The metal jet takes about a hundred milliseconds to arrive. ”

Daniel Zhang thought for a while, and then he said with a serious face: "How long is a hundred milliseconds?" ”

"A second is a thousand milliseconds, so forty milliseconds is a tenth of a second."

Daniel Zhang pondered for a moment, then he nodded and said, "Well, that's fast, you can do it." ”

Xiao Ran couldn't help but say to Daniel Zhang, "Do you really understand?" ”

Daniel Zhang waved his hand and said, "No, I know it's going to be right soon." ”

At this moment, Grevatov's voice sounded in Yang Yi's headphones.

"It's ready, three seconds."

The Black Devil has completed the hoisting of the nuclear bomb, the placement of the tank, and the setting of the time.

Three seconds after the Serpent's ship arrives, the nuke will detonate and the two tanks will turn into jets and hit the Orochi's mothership.

The Orochi know that there are nuclear bombs on Earth, they know the power of nuclear bombs, and humans have indeed used nuclear bombs to launch a counterattack against the Orochi.

But the effect of the nuclear bomb is not good, except for the fact that it can clear the zombies on the ground, it does not play its due role in dealing with the shipboard and mothership of the Great Snake Man.

But humans have never launched manhole covers with nuclear bombs, because there is no such opportunity.

Now that the water organization and the black devil have installed nuclear bombs and manhole covers separately, no one knows whether they can work and how much of a role they can play.

Yang Yi didn't leave, waiting for news from the black devil.

"Good, thirty minutes left, plenty of time."

Glevatov said in a deep voice: "We intend to leave one in case manual control is needed. ”

Yang Yi said indifferently: "No, there is no need for that, if the timing is not good, then manual control is useless, we are spies, it is our style to leave quietly after completing the necessary arrangements, and the black devil is not a young man who pursues blood and passion." ”

Glevatov said in a deep voice: "No, you don't understand, there are always all kinds of accidents. ”

Yang Yi continued: "I believe that the water organization can do everything to the best, if it is perfect before the action, then there is no point in remedying it after the action fails, I believe that the black devil can also do everything to the best, so act in the way a black devil should be." ”

Glevatov was silent for a moment, and then he whispered: "But that's a product of the Soviet Union's time, Poseidon." ”

Yang Yi looked at the spaceship above his head again, and then he smiled and said, "You can't operate it manually, unless you go down." ”

"yes, I just want to go down."

Glevatov did not trust the timed detonation device, nor the remote-controlled detonation device, he said manual control, then it had to be next to the nuclear bomb.

Yang Yi thought for a moment, and then he said in a low voice: "At any time, I will not choose to use suicide to increase the reliability of an operation, I hope none of you have gone down, I think, sitting in a safe place, drinking, looking at the masterpiece we have completed, this is what a spy should do, you don't be infected by the ram's style, remember that you are black devils, black devils should be elegant." ”
