Wang Ning convened the presidents of various discipline associations for a meeting, introduced the tunnel operation plan of Gistine, and then asked the scientific fanatics to help evaluate the construction time and the feasibility of the plan. Pen ~ fun ~ pavilion www.biquge.info

The scientific maniacs got together, carefully calculated, and conducted a comprehensive evaluation, and came to the conclusion that such a long tunnel would not be completed without ten or eight years without manual work.

Gistine was shocked, he never thought that it would take so long to dig the tunnel, ten or eight years is too long, just seize the day.

Wang Ning also felt that if it took such a long time, there would be little point in digging tunnels, so simply stop digging.

Scientists suggest that mechanical construction can be used, which is fast and of good quality, and if it is only a simple tunnel is excavated, there is no need to do complex reinforcement, and dozens of kilometers of tunnels can be completed in about a month.

So I asked the scientific maniacs to find a relationship, urgently imported a set of excavation equipment from China, and began the excavation operation.

This set of excavation equipment, the design is very exquisite, the operation speed is very fast, the back is also connected to a conveyor belt with wheels, the excavated earth and stone, directly through the conveyor belt, transported to the outside, reduce the intensity of manual labor, the speed of excavation is also very fast.

Gistine's hanging heart finally fell back into his stomach, thinking that this was foolproof.

But what Ling Gistine didn't expect was that the United States under the control of the Pillar of the Demon Gate was the world's largest superpower in scientific and technological strength, and the excavation operations on the Sandy tribe's side were clearly seen by the reconnaissance satellites of the United States.

Even the situation of underground operations was detected by the resource exploration satellite of the United States, and the location of the tunnel exit was calculated, and the commander of the Erun Mubia army was notified early.

Saluli sent people to guard around the exit of the tunnel, and the soldiers in charge of the excavation operation on the Sandy tribe's side dug the exit, and as soon as they poked their heads out of the hole, they saw the Erunmubiya soldiers who were waiting around early.

The soldiers of the Sandy tribe, seeing that the situation was not good, immediately retracted their heads, turned around and ran back.

The soldiers of Elun Mubia surrounded them, and shot and threw grenades at the entrance of the cave, and they were very happy.

When she heard the gunshots, she rushed over and ordered the soldiers to stop shooting, and then ordered the pumping machine to be set up, and to start the pumping machine to pump water from the well and fill the hole in the ground.

Fortunately, the soldier in charge of the excavation operation on the Sandy tribe side was clever, and when he saw that the opportunity was not good, he quickly ran back, and did not stop all the way, otherwise, this soldier would probably be poured into the water in the tunnel and drowned in the tunnel, and the consequences can be imagined.

The people escaped, but the excavation equipment was not spared, and it was flooded in the tunnel, and there was no way to continue using it.

The tunnel operation failed completely, and Ji Siting trembled and came to report to Wang Ning.

Wang Ning didn't blame Gisting, after all, the failure of the operation was not Gisting's fault.

The tunnel operation failed, but he couldn't give up the attack on the camp of the Erunmubia army, so Wang Ning invited the scientific maniacs to help them find a way.

Scientists and fanatics believe that the camp of the Ermubia army has set up a phased array radar and is equipped with a very advanced missile defense system, and even missiles cannot pose a threat to the camp of the Ermubia army, and it is even more impossible for unmanned bombers to bomb the camp of the Ermubia army.

As soon as the unmanned bomber on the Sandy tribe's side took off, the enemy discovered the whereabouts of the unmanned bomber from the phased array radar and made preparations early.

Before the unmanned bombers approached the camp of the Ermubiya army, they would be accurately targeted by the enemy's anti-aircraft fire, and all of them would be shot down, and none of them would be spared, and they would not be able to threaten the enemy at all.

After serious discussions, the scientists finally came up with a way to launch an unmanned bomber suicide attack using the tactics of the islanders in the late World War II.

The drone purchased by the Sandy tribe from China this time is a civilian six-rotor drone, which was designed by the Chinese to deliver couriers, with good air stability, super low-altitude flight ability, and can fly close to the ground.

Although the battlefield ahead is an endless prairie with nothing to cover, the whereabouts of unmanned bombers are likely to be unable to escape the surveillance of the enemy's phased array radar.

But unmanned bombers fly at ultra-low altitudes, the enemy's anti-aircraft artillery will not be able to play a role, and portable anti-aircraft missiles will basically be scrapped.

Although the missile defense system equipped with the phased array radar can track and shoot down unmanned bombers, the missiles equipped with the missile defense system are extremely expensive, and the number of defensive missiles equipped with the camp of the Elunmubia army cannot be too large.

On the Sandy tribe's side, there are 9,990 unmanned bombers, even if a few are shot down, it doesn't matter, and the impact on the entire battle situation is limited.

The unmanned bombers on the Sandy tribe's side, carrying bombs of sufficient yield, as long as most of them can approach the camp of the Ermubia army at a low altitude, crash into the walls around the camp, and blow down these walls, it is considered a victory.

The officers and soldiers of Erun Mubia, who were not protected by the wall, became the hunting targets of Wang Ning, Lilina and Sara to play a game of captivity.

That kind of scene makes people sweat coldly on their backs when they think about it, and even the scientific maniacs feel a little sorry for the officers and soldiers of Erun Mubia who have no wall to protect them.

After the plan was formulated, Wang Ning ordered the scientific maniacs to implement it immediately, first dispatching 1,000 unmanned bombers to carry out suicide attacks, specifically to blow up the walls of the camp of the Elun Mubia army.

A thousand unmanned bombers, like a swarm of bees, lined up in a neat queue, clinging to the ground, flew to the camp of the Elun Mubia army.

Sure enough, these 1,000 unmanned bombers flew not far before they were shot down by missiles flying out of the camp of the Ermubiya army.

But then, in the camp of the Elun Mubia army, there were no more missiles flying out.

The missiles of the missile defense system equipped with the Elunmubiya army have all been defeated, and where there are still missiles launched, we can only watch the unmanned bombers swarm in, but there is nothing to do.

1,000 unmanned bombers, swarming up, flew to the area around the camp of the Ermubiya army, bravely rushed to the wall around the camp, and it only took a few seconds to blow up the wall around the camp of the Ermubia army, which was full of holes and lost its defensive function.

In the evening, Wang Ning took Lilina and Sara and set off quietly, touched into the camp of the Erunmubiya army, which had lost the protection of the wall, and began the game of capturing prisoners.

The three of them had a good time, and began to compete to see who caught the most, so the efficiency of capturing prisoners improved by leaps and bounds, and in one night, seven or eight thousand captives were captured.
