Under the protection of the four envoys, Drassus made a detour and slowly flew into the sky.

Ji Tianci asked Fang Qi, "How long will the interval between the seven nuclear bombs fall?" If it is too long, I am afraid that the Youth Alliance will escape from the Evil Sword Fortress. ”

Fang Qi replied with a solemn expression, "Seven nuclear bombs will detonate at the same time. These days, Drassus and I have repeatedly simulated seven nuclear bombs dropping at different speeds to get them to reach a height at the same time.

I made a large nuclear bomb launcher for Drassus, who flew from the extreme distance of space towards Earth, and after each nuclear bomb was launched, he continued to accelerate and then launched a second. Each less nucleus in the launcher will also reduce its mass a lot, and Drassus will not feel as hard to accelerate as he is.

But all this is still difficult to achieve perfectly, and when he flies into space, he will leave the inertial system of the earth. The Earth is constantly rotating, and the equatorial position rotates more than 400 meters per second, so Drassus needs to fly in a curve and drop a nuclear bomb on the infrared position. The slightest deviation in his projection angle could be projected onto other continental plates. Drasus will launch seven nuclear bombs in less than fifteen seconds, and as long as the first nuclear bomb is launched at the right angle, the next few will be much easier. ”

Hao Miao asked puzzled at this time: "Is it so troublesome?"

Fang Qi said angrily: "Do you think it's throwing a flying knife? This is like a fast ship driving on the sea, you throw a flying knife from a long way in the sky, and you need to predict the path of the ship to shoot it." In the Earth's inertial system, we don't have to think about the Earth's rotation, but flying into space, the Sword Fortress is a constantly moving target for Drassus. ”

Hao Miao thought for a while, and suddenly his eyes lit up, "Ah! I finally understood! I used to wonder why I flew into the air and stopped, and the land was still under my feet, since the earth was rotating. ”

Fang Qi was speechless for a while, "According to your idea, as long as the plane flies into the air, it doesn't need to move forward, just stop in the air and wait for the earth to rotate, and it can reach the other side of the world in one day." Have you ever wondered why when you jump on the spot, the landing point is still the same place?"

Hao Miao stroked his long hair and smiled indifferently, "You are a scientist and a prophet, I am just a rough person, it is normal not to understand this." ”

Victoria also said helplessly at this time: "You IQ, I really don't know how you deceived us for so long before, making me think that I always thought that Xingfu Island was an island." ”

Ji Tianci was thinking about other questions, he frowned and looked at the complaining voice, and his heart was even more uneasy, "Do you know that you are not only going to make a very long vacuum channel, but also this channel is very wide? can you really do it?"

Yan Wuyin gently stroked the floating Fu Xiqin in front of him, "He told me that he could." I'm going to do everything I can to keep the sky above the Sword Fortress in a vacuum. ”

Fang Qi also said: "Feng Zheng showed me before, although it was only a short second, he was indeed able to open a spacious vacuum channel, and now he needs to maintain the channel for about fifteen seconds, and I believe he can do it."

Some time ago, I also observed the marching characteristics of the Youth League, and found seven of the most powerful races among them. The seven tribes are now camped separately at the Sword Fortress, and their camp is the target of the nuclear bomb. If the bomb succeeds in destroying seven target points, then there is basically no room for resistance from the Youth League. ”

As soon as he finished speaking, everyone fell silent. Everyone stopped talking because they were nervous, and they all looked at the Evil Sword Fortress, fantasizing about its destruction. Only Fang Qi was holding a holographic tablet, staring at the three-dimensional map of the Evil Sword Fortress projected by it, and there were seven red lines in this picture that were particularly dazzling.

I don't know how long it has been, and the voice of Drassus came from Fang Qi's ears again, "I'm ready, I've reached the specified distance, and I'm flying synchronously around the earth. ”

After hearing this, Fang Qi looked nervously at the complaining voice: "Fengzheng, let's start!"

"Okay, don't come along. ”

As soon as he finished speaking, he was blown into the air by a fresh wind. Soon, he was flying above the clouds, directly above the Evil Sword Fortress.

Complaining silently, he put Fu Xiqin vertically and closed his eyes.

There was a crunch of the "bell", and he plucked a string. I saw that the surrounding clouds were instantly shaken away, and several people on the sea clearly saw a "black spot" floating in a huge cylindrical pillar of light.

Ji Tianci was surprised to find that the sound of the piano was like a "vibration line" perpendicular to the ground, and this "sound line" shook the surrounding air, just forming a cylindrical channel, up to the sky, down to a height of one kilometer above the ground. Observing with Tiantong's eyes, this kind of oscillation seems to be only aimed at the atmosphere, and Ji Tianci saw a strand of hair falling straight down in the passage, doing a free fall movement.

There is no air, and the direct sunlight hits the area, making the passage even brighter and more dazzling, and the cylindrical "pillars of light" are clearly visible.

However, the air that had just been shaken apart was rapidly closing again, and the pillar of light was rapidly shrinking.

The strings were plucked again, and the pillar of light expanded again.

After that, the sound of resentment played faster and faster, as if ten people were playing together, and the afterimage of the hands had changed into dozens of hands, and the pillar of light was slowly expanding.

When it was about to expand to the point where it could cover the entire Evil Sword Fortress, Fang Qi hurriedly shouted, "Quick! Jin Zheng, send a signal." ”

Mai was always ready in the future, and when Fang Qi gave an order, she spread her ten fingers and excites seven infrared rays of different thicknesses as shown on the hologram, leading from the sky above the Evil Sword Fortress to the sky.

However, these seven infrared rays were not directed at the camp of the seven powerhouses of the Evil Sword Fortress, and one ray was even on the sea outside the Evil Sword Fortress. This is also for the consideration of Drassus, if the nuclear bomb falls in space, by the time it reaches the ground, the original target has already moved a considerable distance to the east, so the seven "aiming lines" are also prediction lines.

Only then did Ji Tianci understand how difficult this plan was, and Drassus couldn't make any mistakes in the speed and angle of his head, and the slightest difference would be a thousand miles away......

The vacuum channel finally stabilized, which was only briefly stabilized by the silent and crazy fuqin. Silent has been resisting the earth's atmosphere, and the air pressure of the entire earth has also risen a little bit because of this, although it is not obvious, but the strong people of the Wind Clan can feel it.

In space, Drassus swooped down along seven red lines with a huge nuclear bomb launcher on his back. At first, his speed was not fast, only a hundred kilometers per second.

As soon as he approached the thickest red line, he kept fine-tuning his posture, and when the sensor attached to his eye mask suddenly lit up with a green light, a nuclear bomb in the transmitter on his back ejected.

This transmitter is also made by Fang Qiding, if there will be an error if it is launched artificially, aiming at the infrared rays, when the infrared rays are aligned with the transmitter angle, the nuclear bomb will eject on its own, so that the accuracy will be improved a lot, and Drasus only needs to make the green light appear in the sensor piece in the eye by constantly fine-tuning the attitude.

After the first nuclear bomb was launched, two more values appeared in the sensor in Drassus's eyes, one was his speed at the moment, and the other was the speed he needed to achieve. The two values are constantly changing, and he must reach the specified speed within two seconds to successfully complete the second launch.

He dropped the first nuclear bomb along the thickest red line, and then accelerated closer to the second thick red line and continued to launch the second nuclear bomb.

In space, I saw Drassus's figure constantly accelerating and transverse, like the operation of a machine tool, and in less than fifteen seconds, he had launched all seven nuclear bombs as required. However, even so, there will still be errors, because during the acceleration process, the distance of forward movement is uncertain, and the launch position of each nuclear bomb is also uncertain, which may eventually cause the nuclear bomb to not reach the same height above the ground at the same time.

Inside the Evil Sword Fortress, some of the Youth League soldiers had already looked up at the sky, and the inexplicable pillar of light made them feel strange.

But before they could make any countermeasures, they saw a "meteorite" fall unstoppable.
