Since these planetary engines are disposable, they cannot be used again after one use. However, the cost of these planetary engines is not cheap. The cost of each planetary engine is equivalent to the GDP of a medium-sized country.

Although the cost is so high, even so, in order to transform Venus, the Earth Federation still spent so much manpower and material resources to manufacture these planetary engines. After all, once the transformation of Venus is completed, the living and living space of human civilization will directly expand.

More than twice as much.

After all, Venus is not Mars. Venus is so large that it is almost the same size as the Earth.

After the crew members in these planetary engines had set up all the programming and wires in the planetary engines, Cai Jingjing ordered these Jieyuan to return to space in small spacecrafts and other spacecrafts.

When all the crew members returned to other spacecraft parked in the asteroid belt, Cai Jingjing immediately ordered the operators of these planetary engines to prepare to start these planetary engines.

"Attention all planetary engine controllers. Attention all planetary engine controllers. Please perform self-tests on all planetary engines on Ceres immediately."

Following Cai Jingjing's order, all planetary engine controllers in the fleet immediately conducted self-checks on the planetary engines on Ceres.

"No. 001 engine self-test program is starting, please wait!"

"No. 001, the engine self-test has been completed. Engine No. 001 is normal and can be started at any time." Soon, the self-test of engine No. 001 was completed.

Subsequently, other engines also completed self-tests, and all are normal and can be started at any time.

Seeing this situation, even though Cai Jingjing was a woman, she ordered without delay: "Adjust the direction of the engine port as originally planned and prepare to start the engine."

Following Cai Jingjing's order, all the planetary engines on Gu Shenxian began to rotate in panic, began to adjust the direction of the planetary engine nozzles, and after confirming the angle, stopped and waited for Cai Jingjing's order.

"Fire up!" Seeing that all engines were adjusted in place, Cai Jingjing ordered again.

"boom!………"

Just as Cai Jingjing finished speaking, the more than 100 planetary engines on Ceres all sprayed out blazing white flames. At the same time, the entire Ceres paused for a moment, and then there was a huge vibration.

Although Ceres experienced violent vibrations, it did not affect the engines on Ceres. After all, Zhang Yi and his Colorful Stone Group had already considered this engine when designing this movable planetary engine.

When pushing a planet forward, the planet itself will definitely emit huge vibrations. If the design is unreasonable, it will definitely cause essential damage to the planetary engine itself.

Therefore, at the time of design, all the materials on this planetary engine were the best materials on earth at present, and their cost was very expensive. Even the performance of the materials used in the current federal military space battleships was far from comparable.

Compared with the materials used on this planetary engine.

After all, the materials on the planetary engine not only have to withstand the high pressure and high temperature generated when the planetary engine erupts, but when the planetary engine erupts, the vibrations generated by the planet itself are enough to destroy ordinary materials. In addition, the planetary engine must also have strong

After all, when a planetary engine propels a planet forward, it will definitely be hit by various meteorites. Therefore, the cost of a planetary engine is so high.

As the planetary engine gradually increases its horsepower, the rotation speed of the entire Ceres begins to slow down. At the same time, its revolution speed also begins to slow down. Although this slowing down is very slow, humans cannot tell it at all.

At this time, Ceres' rotation speed and revolution speed have slowed down.

Although it is impossible to distinguish with the naked eye, the revolution speed and rotation speed of Ceres have slowed down at this time, but all of this is under the monitoring of Cai Jingjing's flagship computer, and it can even be said that any trace of anything produced on Ceres at this time

Changes, the corresponding data will be calculated on the flagship super photon computer.

And the super photon computer on the spacecraft will immediately adjust the nozzle directions of these planetary engines on Ceres based on the corresponding data to ensure that there will not be any changes in the flight path of Ceres.

After all, the universe is so vast, and the distance between Ceres and Venus is so far away. If there is any slight change in the flight trajectory of Ceres, the consequences will be very huge, and it may even be impossible to guarantee that Ceres can be accurate.

Hit the predetermined impact point on Venus.

At this time, Guo Jingjing and the others were also always paying attention to the flight trajectories of all asteroids near the femoral nerve to ensure that when the rotation and revolution speed of Ceres slowed down, these asteroids would collide with Femoral Nerve, especially those that

A relatively large asteroid.

Although there are more than 100 planetary engines installed on Ceres, even if the flight trajectory of Ceres changes, Guo Jingjing and the others have absolute means to correct the flight trajectory of Ceres.

However, in fact, even if Guo Jingjing and the others can change the flight trajectory of Ceres, the cost of changing the flight trajectory of Ceres is very high every time. In addition, the energy of these planetary engines on Ceres is limited, so in fact,

On the way from Ceres to Venus, Cai Jingjing and the others were able to change the flight path of the ancient star, but the number of times was limited.

It is for these reasons that Cai Jingjing and the others must ensure that when Ceres flies to the starting point of the Venus impact point, there will be no deviation in its flight path and they must fly according to the predetermined flight path.

Cai Jingjing and the others stood on the bridge of the flagship he was on, looking at the Ceres on the virtual screen, which was slowly rotating. At the same time, it could also be clearly seen from the virtual screen that the Ceres was spinning at this time.

There are hundreds of white rays of light rising into the sky and erupting into the universe, and these white rays of light have pulled up long tails in the universe. According to Cai Jingjing's own estimation, the length of these tails is at least several thousand kilometers long.
