In general, in a quantum jump in space, the lower the jump probability, the farther the jump will be. Correspondingly, the more energy the quantum engine consumes.

Now, Zhang Yuan wants to leave the Golden Sky Domain and jump to a safe jump point, the most reliable way is where he came from and where he goes back, that is, to go back to the jump point next to the Gray Valley Planetary Belt.

That's an ultra-long-range quantum jump distance of more than 20,000 light-years, and the amount of energy required is staggering. Even if the White Angel mecha had a powerful energy core, it would be an impossible task to bear such a huge consumption.

Fortunately, for Zhang Yuan, it is not difficult to design a brand new energy core, and the memory pill that Yu Linglong gave him contains a large number of energy core-related technologies, including the energy core of the top mecha of the end of the world. Golden Sky also has a large number of core energy technologies, although it is slightly behind in technology, but some of these innovations have greatly inspired Zhang Yuan.

Zhang Yuan fused the technical advantages of the two, and while helping Lewis build a mecha, he easily made a one-time external energy core for himself.

This external energy core looks very ugly, it looks like a large box that is 1 meter long, 1 meter wide, and more than 50 centimeters thick, and one side of the box is a simple loading rack, which can firmly fix this energy core on the back of the White Angel Mecha, and 5 thick energy tubes are stretched out under the box, which will be connected to the quantum engine of the mecha, specifically for the power of the quantum engine.

It's not that he doesn't want to make this thing smaller so that it can fit directly into the mecha, but it's too difficult to do so, and in order to meet the needs of ultra-long-range jumping, the energy required can even make a medium-sized warship more than 500 meters long and 400 tons run under full load for a year.

Compressing such a huge amount of energy into such a small box of less than a cubic meter is already the limit of what Zhang Yuan's current technical level can do, and he has no time to specialize in this at present.

Moreover, there is no need to do this, ultra-long-range jumps are more suitable for large warships to carry out long voyages, and the main function of the mecha is combat, and it needs the most ultra-high combat maneuverability. The space inside the mecha is limited, and any technology is also limited, if you take care of each other, it will only lead to nothing being done well, but the gains outweigh the losses.

Therefore, after a series of considerations, the best solution is to install an energy core for the white angel, and an accident will inevitably occur, Zhang Yuan deliberately increased the capacity of the energy core by 50% to deal with the risk.

The White Angel mecha was loaded with this 'big box', and then a protective shell was installed, and suddenly, the entire mecha had no curves, and it couldn't be uglier anymore, looking like a Teenage Mutant Ninja Turtle from a distance.

Zhang Yuan looked the modified white angel up and down, feeling a little unable to look directly.

"Forget it, although it's a little ugly, but there is enough energy, and it is external equipment, one-time use, and it will be thrown away when it reaches the ground."

He waited for a while, and Lewis's mecha was built, and he put this mecha into the space folding equipment, and spent 5 Star Coins to deliver this thing to Lewis.

After doing this, Zhang Yuan entered the modified White Angel Mecha.

'Hum~' In a soft sound, the white angel mecha engine started, and after a few seconds, this 'Teenage Mutant Ninja Turtles' style white angel slowly rose into the air and accelerated, 10 seconds later, the white angel entered space and began to accelerate sharply, flying towards the quantum jump point at the edge of the star field where the golden sky field was located.

Halfway through the flight, the communication on the White Angel mecha suddenly rang, Zhang Yuan glanced down and found that it was drifting snow.

"It's a sharp intuition."

Zhang Yuan smiled, refused the communication, and after thinking about it, he began to sort out the information of the Starlight Land, which also included the relative coordinate map of the Golden Heaven Domain and the Starlight Land.

"One day, the people of the Golden Sky will go out and enter the starlit land. Or one day, someone else will inadvertently break into this star field and break the peace here. I left this information so that the people of Golden Heaven could be prepared. ”

Half an hour later, Zhang Yuan sorted out the information, and in the information, he also attached the design drawing of the energy core he had just transformed, which was a small gift.

'Beep~' A prompt, Zhang Yuan successfully transmitted the information.

"Turn on the warp engine, curvature 100, coordinates (829, 1229, 982)." Zhang Yuan said.

As soon as the words fell, the holographic image in the mecha instantly turned into countless lines, and after a few seconds, the bright lines disappeared, and a dark space appeared again, which was the area where Zhang Yuan had originally come to the Golden Sky Domain.

Manipulating the white angel, Zhang Yuan slowly approached the quantum jump point, and when everything was ready, he whispered: "Start jumping!" ”

In the darkness of space, the silver white angel suddenly lit up, and then disappeared without a trace.

Zhang Yuan once again entered the quantum space-time, and many highly distorted space star maps appeared in the mecha hologram, and an indescribable sense of trance appeared in his mind at the same time, as if time, space, and all the meaning of life had disappeared.

This uncontrollable situation made Zhang Yuan's heart uneasy, and he settled down and used the special ability brought by the Wind Pool Acupoint: the Eye of Insight.

Suddenly, the world in his eyes appeared very strange changes, quantum fields, gravitational waves, rhodium magnetic fields, all kinds of cosmic radiation...... Wait, the universe showed itself to him as it was.

Zhang Yuan became extremely calm, his control over the surrounding situation was unimaginably high, if there was some kind of existence trying to interfere with him at this time, he would definitely be able to detect it at the first time and make adjustments accordingly.

Say Cao Cao, Cao Cao will arrive.

Zhang Yuan suddenly felt a strange force appear nearby, this power gave him exactly the same feeling as in his memory, it was the strange power that appeared at the beginning of the last quantum jump accident.

In the eye of insight, Zhang Yuan clearly felt the fluctuations of the quantum field, and he also felt a cold, dark aura, which felt as if an ultra-low temperature ice blade had appeared near him, and people couldn't help but want to avoid it.

As this force continued to interfere, the abnormal fluctuations of the quantum field became stronger and stronger, and it seemed that it was about to affect his white angel.

Zhang Yuanlin was not surprised, he condensed, and began to adjust the operating parameters of the quantum engine in a targeted manner to deal with this storm.

At this time, the white angel is like a ship running on the sea, Zhang Yuan is the captain at the helm, and the quantum field space is the boundless ocean.

The current situation is that there are waves in the ocean that are about to overturn the ship, and Zhang Yuan, the captain, naturally can't sit idly by, he has to ensure that his ship can survive this storm smoothly.

Under Zhang Yuan's control, the white angel 'dodged left and right' in the turmoil, or hid in the relatively calm sea, or directly confronted the ripples, although the boat occasionally bumped, but never overturned.

I don't know how long this process lasted, but the strange force may have realized something and began to quietly subside, and the quantum field space immediately returned to calm.

Zhang Yuan's heart moved: "This existence obviously wants to destroy me, but instead of going any further, he has taken the initiative to retreat. It was certainly not because of kindness, but because he couldn't do it. From this point of view, even if this guy's means are stronger than mine, they are not much stronger, and they must not be to the point of crushing, otherwise I would have been finished by now. ’

Thinking about it this way, Zhang Yuan's fear of the so-called bad luck was greatly reduced. His only suspicion now is that the other party doesn't know what means to use, and he can always track him.

Zhang Yuan examined himself carefully, but he never found anything special about him: "It's really strange, this guy really has a dog nose!"

After a while, Zhang Yuan's eyes lit up, and the hologram once again showed a clear map of space, in this space, there were gray-white long nebulae, a series of stars, and at the same time, many communication waves carrying signals could be received, which was the quantum jump point next to the Aum Empire's Ash Valley planetary belt.

Returning to the familiar star field, this made Zhang Yuan suddenly exhale a long breath, he glanced at the energy of the energy core, the energy on the energy core of the white angel itself is 97%, and there are about 37% of the external energy core left, and the energy is still quite abundant, enough to support him to jump more than 2,000 light years.

This energy is also enough for him to return to the new star base of the Earth Federation.

"Now back to Nova Base? No, I'm in trouble now, and I'm being hunted down, and if I go back at this time, I'm afraid I'll bring this bad luck back to the Nova base. I'll just pass on the rhodium technology. ”

After the technology was transmitted, he rushed to the Crimson Empire, Lu Meng might be there, and Xia Xiyan, who came out of the Earth Federation with him, was also there.

If these two are well, then he has two more allies. If there's any trouble, he's just in the right place to help.
