However, the crisis of the end times is far greater than the world war, this war of all mankind, once it fails, it is extinction, and the pressure faced by nature exceeds that of the world war, and creativity is also unprecedented.

It is this unprecedented scientific and technological progress that allows human beings to gather all their resources to discover the four-dimensional fragments that are scattered in the three-dimensional universe, and successfully create the wheel of time and space, so that the universe can still be explored without reaching the speed of light.

However, the energy required to start the wheel of time and space is extremely huge, and the current Ye Feng has no ability to start the wheel of time and space again, and even if all the energy of the current human society is gathered, it is difficult to achieve a time and space leap.

Although it is not possible to activate the Chrono Wheel, it can be used as a storage space in another dimension.

The size of the storage space of the space ring depends on the strength of Ye Feng's spiritual power, after all, opening and maintaining a space in another dimension also requires energy, with Ye Feng's current strength of mental power, it can only maintain about 2 cubic meters of reserve space in another dimension.

If Ye Feng's spiritual power was strong enough, he could even easily put an aircraft carrier into the storage space of another dimension, after all, the fourth dimension was infinity for the three-dimensional space.

Ye Feng took out a thick combat knife from the space ring, and whispered towards the inside of the Ya Academy, in an area like the school, where the space is relatively closed and the zombies are relatively concentrated, it is easy to attract zombies with firearms, so as to fall into the encirclement of zombies.

Because it was daytime, the sun was shining, and many zombies had entered various buildings in the school, and there were not many zombies on the campus, which greatly facilitated Ye Feng's sneaking, which was why Ye Feng chose to extract the evolution liquid during the day.

After entering the school gate, Ye Feng came to the right side of the gate next to the sign, where there was a map overview of the school.

"I'm at the west gate of the Academy, and according to the map, the laboratory building should be in the northeast." Ye Feng followed the prompts on the map, found his location, and determined the direction.

After Ye Feng stared at the map for three seconds, he kept the map in his heart, and his body moved, like a nimble black cat, shuttling between the school buildings, and quickly heading towards the experimental building.

The laboratory building is an important building of the Grace College, where there are a lot of valuable equipment and instruments, therefore, the school security department has been paying great attention to the anti-theft measures here, and the windows on the first and second floors close to the ground are installed with guardrails welded by steel bars, which are welded with solid steel bars, not the kind of hollow stainless steel guardrails.

The anti-theft door entering the experimental building is also extremely strong, not an inferior anti-theft door made of a layer of iron sheet and sandwich, but a steel anti-theft door with real protective effect.

In this way, as long as the anti-theft iron door of the experimental building is closed in advance, then the attack of zombies can be easily blocked, and the experimental building is not a teaching building, and there are relatively few students here.

The experimental building, in a sense, is not really used for students to practice, and many times it is just a symbol, after all, the equipment here is very expensive, and once it is broken, it is difficult to say.

The small, well-fortified laboratory building was supposed to be a very good temporary shelter, but it became a nightmare for the students.

"Brother Qing, will we be okay like this?" A thin middle-aged man with sharp-beaked monkey cheeks, sallow skin, and black teeth in his mouth walked to the window while hugging his pants, and looked at a man with glasses with a flattering face.

In the open space behind him, there was a white body lying naked, scattered around the girl's torn clothes, the girl's legs were apart, her expression was blank, and her eyes were dull looking at the white ceiling on the roof.

On the fair-skinned and delicate body of the girl, there were blue and purple pieces, especially between the girl's buttocks and legs, covered with blue and purple and some bright red blood, as well as some men's filth.

"Feng Qiang, you're not afraid of anything when you're so cool, and you only remember it when you're done." The man in glasses turned around and looked at the middle-aged man with the sharp-beaked monkey's cheeks, his face full of disdain.

The man with glasses is named Song Qing, although he wears a glasses, it does not mean that he is knowledgeable, but a genetic disease, and after reaching the age of teens, his eyesight will decline.

Song Qing dropped out of primary school in the third grade, and because of family difficulties, he had to enter the society, did a lot of trades, collected waste products, moved bricks on the construction site, and learned masonry, but when he came to the year of establishment, he still achieved nothing.

When Feng Qiang heard Song Qing say this, his face showed a hint of embarrassment, and he laughed embarrassedly, he, like Song Qing, both make a living by pulling three wheels, they are both bachelors, they are not married, and the situation of the two is similar.

"Laugh at you paralyzed, you don't have a little guts, you are super hammer." Seeing Feng Qiang with a sneering face, Song Qing was angry and scolded directly.

"Brother Song, I just said it casually, don't be angry." Seeing Song Qing, who was a little angry, Feng Qiang hurriedly apologized, although he was more than ten years older than Song Qing, he still flattered and called him brother.

Both of them are people at the bottom of the society, and their family conditions are extremely poor, but Song Qing had a few ruthless fights in society in his early years, knew a few gangsters, and was relatively ruthless, so among their group of people who pulled tricycles, they were like car bosses.

Song Qing and Feng Qiang are both pulling black cars, and in this country where licenses are required everywhere, even pulling tricycles need to hand over an operation license of 4,000 yuan to the Urban Management Bureau, otherwise it will be an illegal operation.

People like Song Qing and Feng Qiang can't save money at all, and their families are poor, and they can't afford to buy a license plate for a few thousand yuan, so naturally they can only pull black cars, that is, wait for the chengguan to get off work.

The main source of customers for the two is also the students of the Ya College, which was formerly a health school, and mainly recruits female students, most of whom come to live a mixed life, and rarely concentrate on studying.

Among them, many female students work part-time outside, and Song Qing and others send these female students to designated places when they need them.

It is also more cost-effective to pull these female students, and even formed an unspoken rule, as long as you get on the bus, at least ten yuan, which is much more cost-effective than pulling other people.

Every time Song Qing pulled these female students, he had dirty thoughts in his heart, after all, these female students were very beautiful, at least in his eyes, hundreds of times better than the dozens of yuan he found under the overpass.

But if you want to get involved with these female students, Song Qing is probably hopeless, although these female students have money to earn, but they also have to divide people, people like Song Qing, these female students look down on them, unless Song Qing can come up with a number that makes them happy.

Song Qing fantasized countless times about pulling these female students to a place where no one was there to satisfy their animal nature, but they just thought about it.

Although Song Qing has no ability to pull three wheels for a living, he is not stupid and understands the power of the state's violent organs, and all corners of the city are covered by Skynet, if you have the heart to investigate, it is easy to find him.
