"Okay, so to avoid you asking, keep blablabla on the sidelines...... Mr. Yan will explain to you the principle of this thing carefully. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info" Yan Yi kept saying. Out of his pocket, he pulled out something that resembled an alien gun from a science fiction comic.

"Ever heard of wormhole travel?" Yan Yi took the gun and looked at a window in front of him.

"I've heard of it, a science fiction. Use the ability of the wormhole to fold the space to achieve an effect similar to teleportation to achieve fast travel ......" Ye Chen on the side paused and continued, "But we are now in another parallel universe, I don't think even the wormhole can help us do this, right?" ”

"Yes, so I'm going to introduce you to the next thing, the Fireworm Cave." Yan Yi pursed the corners of his lips.

Ye Chen looked at Yan Yi with empty eyes: "Why do you call it a fireworm cave?" ”

"Haha! That's because ......" Yan Yi suddenly raised his face and looked at Ye Chen with his nostrils, "I found this thing and named it!" ”

"It's another you......" Ye Chen covered his face with one hand and made a bored look, "Can you talk to me seriously?" ”

"How do you know...... Yan Yi lowered his head the moment he was exposed, and looked at Ye Chen with the top of his head, "Okay, I'll continue." ”

"The state between parallel universes is probably like this......" Yan Yi suddenly came out of a basin of water behind him, and countless water balloons floated in the water. These balloons are parallel universes, and the basin of water that surrounds them is an endless void, and we have no idea what its nature is. Its existence cannot be described by shape at all, it is...... There is no shape. ”

"Shapeless?" Ye Chen tilted his head and looked at the water basin in front of him, "Also, when did your water basin appear?" How did I not know? ”

"It doesn't matter!" Yan Yi's voice raised an octave, and then returned to normal, "Its existence has exceeded the limits of human logic, and we know nothing about it, except for the fact that it exists. ”

Yan Yi suddenly picked up the two water balloons in the water basin and held them up in front of his eyes: "This is the two parallel universes, and this balloon wall is the barrier between the parallel universes, and we can't break through." ”

Yan Yi raised the green balloon in his left hand a little: "This is Universe 837. ”

Then he raised the red balloon in his right hand: "This is the 838 universe we are in." ”

Yan Yi put the two balloons together again and sent them to Ye Chen: "Look carefully, there are two small pieces of red and green in these two balloons, the red represents your colleague, and the green represents you. ”

"Our usual state is like this, you can't get by, he can't get by. The two parallel universes are not related to each other. So how is he going to get here? That's where the fireworm cave comes in. ”

After Yan Yi finished speaking, he put the balloon on the table next to him, and quickly picked up an extremely thin plastic tube and placed it between the two balloons: "What is in your mind now?" ”

Ye Chen's expression became a little embarrassed, but he suddenly thought of something, and he had a sudden expression of realization: "Are these plastic pipes a tunnel that exists between two parallel universes?" And the fireworm cave is the key that opens the entrance and exit at both ends? ”

Yan Yi made a lewd expression on his face: "No, I just want to see if you can associate something with you......"

"......," the excited expression on Ye Chen's face disappeared, "I just reminded you a minute ago, right?" ”

"It's nothing, I'm just trying to adjust the atmosphere, hehe......" Yan Yi's eyes bent to the side, like the yellow squint-eyed villain, "Okay, I think you'll go crazy if I don't say it in ten seconds." ”

"Wait," Ye Chen suddenly covered his eyes, "Can your expression be more serious?" I'm really making a show in front of your face. ”

"......" is now Yan Yi's turn to be speechless.

"Okay, then......" Yan Yi finally picked up the prop again, "You did guess half of it right, the Fireworm Cave is indeed used to connect two parallel universes. However, there is no tunnel between the two parallel universes at all. Giving the Fireworm Cave a huge amount of energy will create the tunnel directly. ”

"However, the fireworm cave is very small. Although it is true that it is all around us, and it is not difficult to find it once you have mastered a certain method...... However, it is indeed small, and there is no way to expand it to a limited extent with the existing technology. If we really want to use it to teleport things between two universes, we need to shrink the object down to a subatomic level to ......."

"Wait." Ye Chen suddenly stopped Yan Yi, "Do you know what the concept of subatomic level is?" In that state, all time and space have no concept! So how do we find what we teleported? ”

"I'm sorry......" Yan Yi scratched his head embarrassedly, "my mistake, my mistake, in fact, we need to shrink the object to a slightly larger size than the subatomic level." ”

"But even if we were able to teleport, it would be one-way, and we needed something else to direct the energy, like a magnet to pull the 'cargo' to where it should be. Otherwise, they will randomly end up somewhere else. And the rest of the world could be a crater, high in the sky, on the other side of the world...... And the most likely place is the deep sea. ”

"And this energy-oriented thing...... is an artificial black hole. Its immense energy is capable of ......"

"Stop again!" Ye Chen interrupted Yan Yi again, "Can you really guarantee the normal generation and destruction of black holes?" If one is not careful, the entire solar system may be destroyed by you. ”

"Shall I create another black hole and destroy it?" Yan Yi shook the "alien gun" in his hand, with a disdainful expression, "And this operation is completely completed by this machine in my hand, you don't need to worry about it at all." The energy regenerated by the explosion is also reabsorbed, and the whole process is completely dangerous, and I can put it on my head and launch it. ”

"Well, I'll just believe you...... It's a big deal, it's just a death. Ye Chen held his forehead and said painfully.

Yan Yi pursed his lips, took the gun and fired a random shot at the window in front of him, and a display suddenly appeared in front of their eyes, which looked very "magical".
