Time is urgent, Du Xingyu has no time to explore the question of who put the small universe four billion years ago. He needs to find the ultimate weapon of the level five civilization!

Du Xingyu took matter from the entropy-decreased universe and explored its properties.

He found that matter taken from this reverse world, because of its properties opposite to the universe they are in, will soon disappear.

"Matter in the reverse world is relatively to us, an antimatter. But it is not the antimatter weapon we use, the antimatter reactor." Du Xingyu discovered through research.

"Antima in the reverse world is an antimatter with a special symmetrical property."

"Special symmetry?" asked an academician who has been engaged in antimatter research for many years. "You mean that antimatter in the reverse world only produces annihilation reaction to the same positive matter in our positive world?"

"This is just my guess. You can tell if you try it!" Du Xingyu took out a rusty metal piece from the reverse world.

Similarly, he took out the same coordinates and the same piece of metal in the human universe, that is, he was taking out the same metal plate from the world.

Both metal sheets are wrapped in quantum film so that they do not receive any influence from other particles or space.

In the test site, Du Xingyu put two metal pieces together.

"These two metal sheets belong to the same substance, but one is a matter that is positive and the other is a matter that is reversed and the other is a matter that is reversed."

"Open the quantum membranes and let them contact them to see what reaction will occur!" Du Xingyu ordered.

"Yes, the quantum membrane has been opened." The intelligent system begins to operate.

Under the observation of everyone, the same substances in the two worlds, both positive and negative, come into contact with each other.

At the moment of release, they burst out with powerful energy.

This energy exceeds the energy generated by normal annihilation of positive and anti-matter, and is even accompanied by the energy of space annihilation.

The entire reaction process is less than one ten thousandth of a second.

Du Xingyu has a four-dimensional eye and his brain has also been transformed by light quantum information. He can see clearly in this ten thousandth of a second!

The moment the two fast metal sheets come into contact, they undergo drastic changes!

The metal sheets that are positively oxidized, decayed, and rotted into the most basic particles.

The metal sheets in the reverse world begin to deoxidize and become completely renewed from rust.

Then, the two began to undergo an annihilation reaction of positive and antimatter.

This annihilation reaction is also annihilated with the space where they are located, so the energy burst out is amazing!

"Incredible!" exclaimed the academician who studied antimatter, "The energy level just now exceeded the normal antimatter annihilation reaction of more than a hundred times!"

"In addition to the energy in space, there should be other energy bursting!"

"Yes, there is also the energy of dimension!" Du Xingyu affirmed his guess, "The annihilation from four-dimensional space!"

"The energy of the four-dimensional space annihilated?" Everyone was surprised.

Although humans can now use dimensional energy, they only use some of the energy of dimensionality reduction in high-dimensional space.

Humans can't really annihilate the four-dimensional space.

But in the experiment just now, a small part of the four-dimensional space was annihilated!

Du Xingyu repeatedly analyzed the experiment just now and conducted several similar experiments.

The results are the same. When the matter in the positive world and the same species designed in reverse, or when two symmetrical matters in the timeline come into contact, strong energy will burst out and "burn the timeline" at the same time!

"Suppose that the matter in the positive world exists in a four-dimensional space with entropy increase, and the matter in the reverse world exists in a four-dimensional space with entropy decrease."

"The two are located in the space, two sections of the timeline of the matter."

"The origin represents the space becoming nothingness, and the beginning and end of time are also the end."

"In the positive direction of the time axis, it is the matter that is positive to the world, and the negative direction of the time axis is the matter that is reverse to the world."

"When the two come into contact, the timeline is like a lead wire that is ignited at both ends at the same time, approaching the origin of the timeline!"

"In the end, both points returned to the origin of the timeline. During this period of timeline, the time in these two four-dimensional spaces ended, and these two four-dimensional spaces were annihilated!"

When Du Xingyu got the conclusion, he was overjoyed.

"That's what I'm looking for!"

“A method to target the timeline!”

...

He had already figured out this method vaguely and believed that he would come up with it soon.

Before this, if we started a war with the saint civilization, Du Xingyu would be fine at this time.

Because he has a whole reverse universe, all the matter in this reverse world can be used as a weapon!

These entropy-decreased matter, in their positive universe, will show physical properties opposite to normal matter, and are themselves weapons.

In addition, after reacting with a forward symmetric substance, it is equivalent to a small "four-dimensional time bomb".

This weapon is no less powerful than a two-way foil.

Before the showdown with the Saint Civilization, Du Xingyu had to go to the devil civilization to ask clearly.

The four-dimensional creatures of the devil civilization are relaxed. Since surrendering to humans, most of them have entered deep sleep.

Only a few four-dimensional creatures are taking turns on duty, and it is said that they can sleep for tens of thousands of years.

Du Xingyu contacted the four-dimensional giant beast on duty, whose name is "Chen".

"Chen, I need all the information about the saint civilizations you know." Du Xingyu said.

"Saint civilization, have they arrived at the door?" Chen Xun became alert.

If the saint civilization comes to the door, he thinks it is better to run away first.

Because for the saint civilization, they are military achievements.

"Not yet, but a war will soon happen between us." Du Xingyu said truthfully. Even if he didn't say it, the four-dimensional creatures could know.

These four-dimensional creatures seem to be sleeping, but in fact they have always kept their attention to the outside world.

The war between the two sides will definitely not be small, they will definitely notice it.

"You are going to fight against the saint civilization?" Chen said in surprise, "I suggest you give up, you are not the opponents of the saint civilization."

"If you have any means, you can use it quickly, or escape from the Great Magellanic System. We devil civilization doesn't want to be buried with you!"

"It is impossible to run." Du Xingyu said a piece of news that shocked Chen. "To be honest, the space around him has been locked by the saint civilization. Even if we want to leave, it is afraid that it is impossible."

"What? Why didn't you tell us earlier?" Chen said angrily, "If we had known, we wouldn't follow you!"

"Parts, wake up quickly, the crisis is coming!"
