The nuclear bomb was put into the deep well, and then a layer of sand was laid around the wellhead. Finally, an M1A2 tank was driven to the wellhead.

The seal isn't particularly good, but it's adequate.

"time!"

Zhang Yong immediately placed a digital watch in front of Gao Yuan. The time displayed on it was 42 minutes and thirty-six seconds remaining.

Looking at the electronic watch, Yang Yi entered the number of forty-two minutes and forty seconds on the timer without any hesitation.

Looking at the numbers entered by Yang Yi, Zhang Yong hesitated for a moment, and then he couldn't help but said: "Is the time too short? Only three seconds? Or set it to one hour? What if the snake man comes late?

Well, in case the height is not enough, manual operation is more suitable, I will stay and prepare for manual detonation."

Yang Yi completed the input. He watched the numbers on the detonator begin to flash, indicating that the timing had been completed. He breathed a sigh of relief and said: "No, the Orochi's time is accurate enough. There is no need to leave too much time. Compared with Loud

If we can’t arrive on time, I’m even more worried that the Orochi’s mothership will leave again.”

Zhang Yong said cautiously: "Does this... work? Your detonator is useless, why do you keep it?"

Yang Yi shook his head and put the detonator in his pocket that had completed the time setting and could no longer be reversed.

"Leave a souvenir."

Yang Yi clapped his hands and said: "Anyway, this is the first time since the invasion of the Orochi that mankind has mastered the precise movement trajectory and time of the Orochi. It is also the first time since the invasion of the Orochi that mankind has obtained effective military intelligence.

The first ambush operation was carried out on this basis, so whether it was successful or not, we at least conducted an ambush operation."

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

"Black Devil received it, three seconds."

Yang Yi put down the walkie-talkie, and Zhang Yong couldn't help but said: "What can this tank be used for? Can you explain to me why it is necessary to cover the wellhead with a tank when it is put in the well?"

Yang Yi looked up at the spaceship in the sky.

"The manhole cover plan originated from a reason used by the Spark Team led by Gao Yuan to fool people during the expedition. But after I heard it, I felt that this plan was very likely to be realized, because we finally accurately grasped the big snake

We also obtained two nuclear bombs and deep wells that are not uncommon in cities."

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

Zhang Yong scratched his head, and then he said seriously: "I understand what you are saying, but what does the machine cover mean? Why is it called the manhole cover plan? You can call it the tank plan, or you can call it firecrackers, but why is it called the manhole cover plan?

?Oh oh oh, I understand, this tank looks like a manhole cover when it is placed upward, but why did Gao Yuan call it the manhole cover project? "

Xiao Ran frowned and said: "Brother Yong, don't interrupt, just retreat."

Gao Yuan waved his hand, and then he said to Zhang Yong: "The reason why it is called the Manhole Cover Project is because this plan really originated from a manhole cover. In 2957, the Americans conducted an underground nuclear test at a depth of 150 meters and a diameter of 1.2 meters.

A nuclear bomb was detonated in a pit measuring 70 meters, and then the iron manhole cover covering the deep well shot into the sky at a speed of nearly 70 kilometers per second and disappeared, becoming the fastest flying object in human history."

Zhang Yong nodded and said: "Oh, that's right. It's just a manhole cover? What next?"

"The nuclear bomb we are using now has a yield of one million tons, and the tank weighs 60 tons. The speed may not be as fast as the manhole cover, but it may also exceed the manhole cover. The tank will turn into a metal jet due to the violent friction between the shock wave generated by the nuclear bomb and the air.

, part of it vaporizes, and part of it scatters and disappears, but according to calculations, it is still guaranteed that the residual jet of more than five tons can reach a height of three thousand meters. Well, the Orochi's mothership is hovering at a height of six thousand meters above the ground.

, and at this height, it takes about a hundred milliseconds for the metal jet to reach."

Zhang Yong thought for a while, and then he said seriously: "How long is one hundred milliseconds?"

"One second is one thousand milliseconds, so forty milliseconds is one-tenth of a second."

Zhang Yong pondered for a moment, then nodded and said: "Well, that will be quick, we can do it."

Xiao Ran couldn't help but said to Zhang Yong: "Do you really understand?"

Zhang Yong waved his hand and said: "No, I knew it would be right soon."

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

"It's ready, three seconds."

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

Three seconds after the Orochi's spaceship arrives, the nuclear bomb 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 the earth and the power of nuclear bombs, and humans have indeed used nuclear bombs to fight back against the Orochi.

However, the effect of the nuclear bomb is not very good. In addition to clearing the zombies on the ground, it does not play its due role in dealing with the Orochi's spaceship and mothership.

But humans have never used nuclear bombs to launch manhole covers, because there is no such opportunity.

Now that the water organization and the Black Devil have separately installed nuclear bombs and manhole covers, no one knows whether it will work or how much it will work.

Yang Yi didn't leave, waiting for news from the Black Devil.

"Very good, there are still thirty minutes left, plenty of time."

Grevatov said solemnly: "We plan to leave one in case manual control is needed."

Yang Yi said indifferently: "No need, there is no need. If timing doesn't work, then manual control is useless. We are spies. It is our style to leave quietly after completing the necessary arrangements. The black devil is not pursuing

A passionate and passionate young man."

Grevatov said solemnly: "No, you don't understand, there are always various accidents."

Yang Yi continued: "I believe that the water organization can do everything to the best. If it is perfect before taking action, then there is no point in making up for it after the action fails. I believe that the black devil can also do everything to the best."

Okay, so, act as a dark devil should."

Grevatov was silent for a moment, and then he whispered: "But that is a product made in the Soviet Union era, Poseidon."

Yang Yi looked at the spacecraft above him again, then he smiled and said: "You can't operate it manually unless you get down."

"Yes, I just want to go down."

Grevatov does not trust timed detonation devices, nor does he trust remote-controlled detonation devices. He is talking about manual control, which must be next to the nuclear bomb.

Yang Yi thought for a while, and then he whispered: "At any time, I will not choose to commit suicide to increase the reliability of an operation. I hope that none of you have already gone down. I think that sitting in a safe place
