On the earth, the island of Chentu, where the Ocean Group is located, is already in the golden autumn season, and it is the harvest season. It's just that at this time, everyone's eyes are mostly in space.

In space, an unprecedented experiment is about to begin.

On Zhang Hao's left hand side is Zhang Xiaoning, the son of Zhou Xueyao, who is now a master of the Cave Void Realm, and is only one step away from the True Realm. Not only is the cultivation excellent, but the science and technology and research are also among the best, this time in the research and development of time travel technology, Zhang Xiaoning has participated in the research and development of core technology.

Now Zhang Xiaoning can already take charge on his own.

On Zhang Hao's right hand is Zhang Xiaoxia, a slim daughter who has just grown up. This is the daughter of Zhang Hao and Li Yuanyuan. Like most girls, although Zhang Xiaoxia has a good background, she does not like science and technology.

On the other hand, like most royal princesses, Zhang Xiaoxia has liked politics since she was a child, and has targeted Liu Xinyu!

Now he has repeatedly said that he wants to meddle in the diplomatic affairs of the Ocean Group, but he has been pressed by Zhang Hao. The girl's family has such an idea, which is a little bit inconsistent with international safety standards.

In addition, Liu Xinyu also brought the crown prince Liu Xinhai over. The current Liu Xinhai is 43 years old, but with a mother like Liu Xinyu, he can only do other things in the name of the prince for the time being.

In fact, the current princes of all countries in the world and the heirs of major groups are in such an embarrassing position. Even Zhang Xiaoning, the 'prince' of Dayang Group, can only participate in scientific research and strive to be able to preside over one side, not the overall situation.

Zhang Hao still had too many people around him to watch the ceremony together.

In the space ahead, a specially built spaceship is ready. Compared to other spaceships, the engines and nuclear fusion core of this spacecraft occupy half the volume of the spacecraft.

The entire spacecraft looks more like a stubby rocket, with six engine units 'strapped' to the back, each with nine plasma engines.

There's also a major engine cluster at the very center, with a full 27 engines – that's more than that.

There are also 20 engines on the side of the spacecraft and even in front of it, which are used for steering, deceleration, etc.

The spacecraft is about 300 meters long and 60 meters in diameter, and its overall mass reaches 120,000 tons, exceeding the theoretical value of 80,000 tons - according to the calculations of the Ocean Group and the data obtained from the Xuanhuang civilization, only when the mass is greater than 80,000 tons, when it reaches 0.3 times the speed of light, can it stir up the folds of space-time.

If it's too low, it won't work, and it will 'drift'. It's too high, and the engine doesn't give power.

With the current technology of the Ocean Group, such a spacecraft is already the most economical design at the moment. No matter how big it is, it is not impossible, but the cost will increase exponentially.

The ship's technology, including the latest magnetofluid generators, the latest plasma engines, the latest artificial gravity systems, and the latest particle weapons, the proton cannons, are all necessary technologies for time travel. The proton cannon, in particular, is the best weapon to break time and space - temporarily, but also theoretically.

The proton cannon can be regarded as an alternative particle accelerator, which accelerates a series of protons to 0.99 times the speed of light, and in this state of extreme speed, under the premise of the fold of space-time, the proton cannon carrying electric charges and electromagnetic fields has the hope of interrupting the continuity of space-time.

It's really high-tech, but it's also a really dangerous test. This is a challenge to the rules of time and space, and it also uses a lot of methods to "deceive the world". If you don't do it properly, I'm afraid that even a master of the True Realm will be crushed by time and space, and even atoms will not be left.

The pilot, or captain, in charge of this test is Feng Songjie, and the deputy captain is Yu Jiang.

The two became pilots as early as when the Dayang Group produced the first passenger aircraft. Since then, they have evolved, but eventually joined the space sequence and fought their way out of the encirclement, becoming the pilot of the first chronospace, the Voyager.

And the cultivation of the two of them has also reached the realm of returning to the truth! No one can know what kind of problems will be encountered by the time and space shuttle, so the captain's cultivation is higher, and it seems to be more secure.

The rest of the crew are almost all talents who have cultivated in the Cave Void Realm and have considerable scientific literacy. These talents are important talents even here in the Ocean Group, but in order to test this completely self-produced chronospacecraft of the first ever Tian Yuan Star, they have to undertake this extremely dangerous mission.

There are too many dangers in this task.

If the time-travel is successful, what if we can't find our way back? This possibility is quite high, according to the calculations of the spacecraft designer Lin Yinghao, plus Zhao Dahe's astronomical calculations, the probability is as high as half.

Note that this 'half' refers to the premise that the timetravel is successful. If it doesn't work out, forget it.

In addition, there is a half-chance of dying during the time-travel - there is a half-chance of dying while entering the time-travel. Everyone now knows nothing about the four-dimensional world and the theory of time and space. It's just that the huge pressure to survive makes everyone have to take risks and try technology.

In the end, the spaceship can interrupt the continuity of space-time and cut into the super-space-time level, which itself has a probability of only 30%!

In the end, even if everything goes well, in case of encountering a powerful alien civilization and a not very friendly alien civilization, everyone needs to choose self-destruction at the first time, absolutely and completely self-destruction, to prevent being captured.

In short, this is not a mature technology. And the people involved in the test have already prepared suicide notes in advance.

Because of such danger, such strictness, and the need for secrecy, all the people who temporarily participated in this plan were the people of Dayang Group.

Zhang Hao watched quietly, and did not give an order at all.

It was the scientists who really gave the order to ignite. This is not a military operation, much less a cool acrobatic performance, this is a serious scientific study. Therefore, when to ignite, it is up to a professional to judge.

Under the command of the commander-in-chief, Lin Yinghao, the spacecraft began to ignite. First comes the heat engine and the test. The engines on the spacecraft were fired in pairs, and it was a powerful pulse ignition. After an hour-long inspection, all engines are in perfect working order.

Then, after another 17 hours, the order was given for all the ignition.

At this time, astronomically, the tangent direction of the rotation of the Tian Yuan Star is about the same as the tangent direction of the Sun's revolution, so that the spacecraft will directly borrow the orbiting speed of 30 kilometers per second when taking off from the Tian Yuan Star, and because its forward direction is exactly the same as the rotation direction of the Sun, it can borrow the speed of the Sun's revolution - 250 kilometers per second!

All engines emitted pale blue tail flames, which were hot plasma. The tail flame then gradually increased, and finally after a minute it turned into a pale blue pulse with a tinge of purple. Behind the entire spaceship, like a small blue sun, the heat scorched the people thousands of miles away—at this time, the spacecraft had already flown thousands of miles away.

At this point, the engine was fully turned on, and the ship rushed out with an acceleration of 500 meters. The acceleration of 500 meters is enough to press an ordinary person into a potsticker. Fortunately, the lowest cultivation on the spaceship is the Cave Void Realm.

The spacecraft flew out in the tangential direction of the orbit of the Tian Yuan Star. In this way, the maximum speed of the Tianyuan star itself can be borrowed - 30 kilometers per second.

Although the speed of 30 kilometers per second is almost negligible at 0.3 times the speed of light and about 90,000 kilometers per second, it can save a little.

Under the gravitational pull of the sun, the spacecraft made an arc that became more and more open, and 'gradually' moved away.

When the spacecraft accelerated for ten minutes, the spacecraft was already more than 100,000 kilometers away from the Tianyuan Star, and had already broken away from the orbit of the Tianyuan Star and rushed towards outer space.

At this time, the speed of the spacecraft is about 320 kilometers per second (relative to the Tianyuan Star). The flames behind the spaceship are still purple and blue, which is beautiful.

When the spacecraft accelerated for 30 minutes, it had already left the Tian Yuan Star about 1.8 million kilometers, and the speed of the spacecraft had reached 920 kilometers per second compared to the Tian Yuan Star. By this time, the purple-blue tail flame behind the spacecraft had begun to fade in purple. Redshift has already begun to appear.

However, at this time, it was almost impossible to distinguish the tail flame of the spaceship with the naked eye, even if it was a master of the True Realm. It can only be observed by detectors arranged in front of it.

By 10 hours of acceleration, the spacecraft had reached a speed of 18,000 kilometers per second (relative to the sun). At this time, the tail flame of the spaceship was completely devoid of purple, and the blue was no longer so translucent, and a faint red halo had begun to appear. The redshift phenomenon has begun to be noticeable.

At this time, the acceleration of the spacecraft was also reduced from 500 meters to 492 meters.

However, at this time, the spacecraft had already left Tianyuan Star 330 million kilometers. The spacecraft has cut into the outer orbit of Jupiter. At this time, the flight trajectory of the spacecraft is almost a straight line, and the gravitational pull of the sun is almost negligible.

At this time, the direction of the spacecraft basically coincides with the direction of the sun's revolution.

The spacecraft was still accelerating, passing Jupiter, then through the orbits of planets, and after 36 hours, it finally passed through the orbit of Pluto, the outermost planet of the Celestial Star star system, and entered the outer part of the star system. And the spacecraft has traveled a distance of more than 3 billion kilometers.

Here the gravitational pull of the sun is already extremely low, and the spacecraft continues to accelerate.

At this time, the tail flame of the spacecraft seen from the telescope was already clearly red. The redshift phenomenon is already very noticeable. In addition, as the speed increases, the mass of the spacecraft also increases, so the acceleration ability of the spacecraft gradually decreases from the initial 500 meters to 422 meters.

The speed of the spacecraft has reached 59,100 kilometers per second! It seems that the speed of the spacecraft has been completed by 60% from the expected speed of 90,000 kilometers per second!

But the real difficulties have only just begun.

As the speed continues to increase, there will be some changes and disturbances in the workload of the plasma engine. Time, space, and energy inherently affect each other. And as the speed increases, the redshift becomes more pronounced, and the ship's acceleration ability begins to decrease. The energy consumption of the spacecraft is still rising.

The increase in energy consumption and the decrease in power caused the ship's hull to tremble.

Captain Feng Songjie calmly checked the operation status of the engine and the nuclear island, and after consulting the computer control personnel, he ordered the load to be reduced by 3%.

The ship's acceleration ability is affected in some way, which will take more time to reach the expected speed. However, the ship's performance stabilized.

The spacecraft continued to accelerate, and after another 54 hours, the spacecraft finally reached 30% of the planned speed of light, which is 90,000 kilometers per second. The speed is even slightly more than that.

On the spacecraft's brand-new detection instrument, space-time ripples appeared as expected, which can also be called space-time folds.

On the probe, one or two inconspicuous waves appear in the space ahead, and they appear hemispherical in front of the spacecraft.

This fluctuation is still invisible and intangible, but with the help of professional detectors, it can be detected - the front rays, electromagnetic rays, etc., are distorted and refracted by them.

Time and space have become extremely unsmooth!

Feng Songjie took a deep breath and ordered: "The engine power is retained by 55%, and the engine is checked in turn."

The rest of the energy is transferred to the proton cannon. The proton cannon is ready to store energy, check the parameters of the proton cannon, and be sure to achieve zero error!

The reconnaissance team prepares, summarizes the law of space-time folds, and calculates the best attack time for the proton cannon!

The rest of the crew is in position and ready according to the training. Remember, in space, in time travel, no matter what happens, be sure to protect the ship!

Without spaceships, all of us would have no return.

Combat group, dressed mech. Level 1 Preparation!"

"Yes!"

The crowd replied solemnly.

The atmosphere became serious, and the countdown ended little by little. Finally, at a certain moment, when all the data was summarized to Feng Songjie, Feng Songjie and Deputy Captain Yu Jiang signed their seals and officially issued an order:

"Proton Cannon, fire!"
