Ye Wanting disappeared again, her ability to travel through time was too unstable.

I don’t know how many years it was, maybe two years, or three years, Ye Wanting appeared again, and this time she was already twenty-five years old.

But what she exuded was calmness in her eyes, as if she had experienced countless times and countless sufferings.

"I finally got back here. It seems that it is still stopping here. Su Yu is in a lot of trouble." Ye Wanting was very calm. She did not go to drive the boat as soon as possible, but went to the scientific research room.

"I can't waste slave transport ships anymore, there are only two ships." Ye Wanting thought calmly, "I have to build my own shuttle to cross the border, so that I can continue to build shuttles every time I disappear halfway."

But this is very difficult for Ye Wanting because he had to build a shuttle from scratch, which is not low.

"I can use my abilities and once I go through the future, I will get the technology of the shuttle."

Ye Wanting started to wait, and a few days later, she disappeared again.

Then, the world of time began to wait with peace of mind. I don’t know how many years later, the twenty-six-year-old Ye Wanting once again came to this time and space.

She became very calm, so calm that she was terrible, as if she had experienced life and death.

"Su Yu, you were indeed very cute when you were a child, and your abilities were indeed very magical. No one knows what your future will be like, but you can only explore it yourself. I can only be here." Ye Wanting smiled with relief, and then she walked into the machinery factory and began to build a shuttle.

"Ye Wanting, you did a good job, you have succeeded." Ye Wanting knew that she was the only human on earth who could act.

She also knew that only she could drive the shuttle to the world where Su Yu was.

"This is the first time." Ye Wanting built a single shuttle at the fastest speed. She did not consider the others, but instead considered Su Yu.

As long as Su Yu can come back.

A single shuttle is a sphere spacecraft that can only allow one person to enter, and one person has to bow his body when he goes in.

But it can indeed travel through all worlds and consume only a small amount of fuel.

Ye Wanting made it out and then sat in.

"Let's start!"

The shuttle machine immediately ejected out and passed through the world barrier, but after leaving the world for a few seconds, Ye Wanting disappeared and she traveled through time and space again.

Then, many years later, Ye Wanting appeared here again. Then, she continued to use a single shuttle to leave, but the situation was still the same. She disappeared a few seconds after leaving the world.

"This is the third time, I must succeed!" Many years later, Ye Wanting appeared again and left in a single shuttle he built, but the situation was still exactly the same.

At that moment, Ye Wanting was desperate.

"So I can't leave this world?"

This time, she was not so calm, but full of despair.

"It turns out that I can't leave this world. Once I leave, I will force me to travel through time." Ye Wanting showed despair on her face, and tears fell from the corners of her eyes.

After countless years of persistence and countless attempts, I finally made a shuttle, but I couldn't leave.

Her abilities are obviously not as powerful as Su Yu. Only in the Evolution world can Ye Wanting's abilities be activated, and there are side effects, that is, Ye Wanting cannot leave this world.

Ye Wanting was desperate. He did nothing this time, just wandering around. She was very lonely because she hadn't seen Su Yu for a long time.

"Are I doomed to be unable to succeed?"

"Will time stop forever?"

"Can't Su Yu come back?"

Ye Wanting wandered around in despair, finally came to Su Yu's residence and looked through Su Yu's notes.

These are not very important notes.

But these are all the events recorded in a timely manner over a hundred and fifty years.

Although something happens only a few years later, Ye Wanting still sees Su Yu’s hardships. At the same time, Ye Wanting also sees the spiritual chicken soup that Su Yu cooks for herself.

"Tonight, I am the only one who chooses God and is also the only one."

"The hymn of mankind is the hymn of courage, and the greatness of mankind is the greatness of courage!"

"What can a cowardly person burn away except for the weak grass?"

"What is a road? It is trampled from a place where there is no road, and it is opened from a place where there is only thorns."

Ye Wanting finally understood that Su Yu could firmly believe in the hundreds of years and move forward bravely because he cooked the chicken soup well!

Ye Wanting seemed to have gained strength and faith.

"I have to find out the truth about my ability," Ye Wanting kept thinking, "and then, control this ability and let it be used by me."

I can no longer be so passive, I must be able to perfectly control this ability!

"Whether it takes a year, ten years, or a lifetime, I have to control my abilities!" Ye Wanting made up her mind and then immediately started to take action.

"Is my time travel really random?" Ye Wanting began to sort out her time travel time travel time and time again with her memory.

"Will my time travel trigger any condition?" Ye Wanting kept thinking and constantly searching for the characteristics.

"Is time really continuous? In four-dimensional and five-dimensional space, is time really a straight line?" Ye Wanting asked boldly.

Finally, Ye Wanting made a bold guess: "If I were no longer me, will my ability be activated?"

Part of Su Yu's body - hair and nails can recover and stop. What about me? Can part of my body trigger the shuttle between time and space? If I change my body, will I still trigger the travel between time and space?

Ye Wanting started to try it. This spacecraft was very bold and even unnecessary, because it might kill her.

But Ye Wanting was determined.

"What's the point of a world where I'm the only one?"

Ye Wanting disappeared again.

The next time she appears, it is time for her to make a change.

It has been a long time since Su Yu has been in trouble, and it is estimated that it has been a hundred years.

Over a hundred years, Su Yu built a research institute from scratch on this imperial city and thoroughly studied the cause of the death of the gray man.

It was a terrifying substance, which Su Yu called it the extremely cold seed. Its body size is smaller than atoms and is an inorganic substance. Its characteristic is its absorption of heat energy.

This absorption is not infinite. Every extremely cold seed has an energy limit, which can be called an energy storage device.

As long as the reverse operation is performed, the stored energy can be released. This operation is not difficult, because it is exactly the same as the principle of reversible chemical reactions in the laboratory.

Lithium batteries are made based on this principle. When the lithium battery is discharged, the lithium atoms on the negative electrode will decompose into electrons and lithium ions; when charging, the lithium atoms on the positive electrode will decompose into electrons and lithium ions under the action of an external power supply, so that the lithium ions will move to the negative electrode through the separator, and the electrons will move to the negative electrode through the external circuit. The lithium ions that reach the negative electrode will form lithium atoms after encountering electrons.

Therefore, this extremely cold seed has the same characteristics as a battery. As long as it is used properly, it can not only charge Su Yu, but also charge the warship.

"I didn't expect to find such a treasure in such a place!" Su Yu sighed. The aliens in this world used this extreme cold seed as a biological and chemical weapon, but they didn't know that this thing could be made into the most terrifying battery.

Su Yu calculated that an extremely cold battery can drive an electric vehicle for more than 75 years, and once the power is charged, the nuclear power plant must be fully operated for more than one day.

Too strong!

The problem of new energy vehicles has been completely solved by Su Yu.

One-time charge, can drive for 75 years!

Just as Su Yu sighed, a void wave came out in a faraway place in this world, and ripples in space continued to appear, as if someone was coming.

But at this time, how could there be others?
