The next day, Song Yan took Xia Lin to visit the "Midnight Flight" bar.

This bar is not unfamiliar to Xia Lin. In his previous life, he and Song Yan came here a few times. Although he didn't mix up with bars in this life, he was taken here by Ke Mei once in his senior year.

He looked at Song Yan dumbfoundedly: "So, are you sure we are going to the bar instead of the hospital to treat me?"

Song Yan smiled and did not explain much.

After entering the bar, a waiter who met him politely said: "Brother Mei is already waiting in the room."

The two followed the direction pointed by the waiter and saw Ke Mei leaning against the door of a certain room, smiling and waving at them. Song Yan patted Xia Lin's arm and steered the wheelchair to the other end of the bar.

Xia Lin was about to ask where Song Yan was going but Ke Mei had already greeted him: "Xia Lin, long time no see. Let's go into the room to talk."

Xia Lin was still watching Song Yan in the other direction. The assistant entrusted Song Yan to him so solemnly. He couldn't lose Song Yan in a place where people just come and go.

"Song Yan still has something to deal with." Ke Mei smiled, "Don't worry, he knows this place better than you so he can't get lost."

Xia Lin suddenly realized that he knew too little about Song Yan. Song Yan has changed a lot in this life and he feels strange in many aspects.

He frowned and said: "Are you plotting something? What are you hiding from me?"

When Song Yan entered Song Huaixin's lounge, Song Huaixin and Du Lanze had been waiting for him.

"You really brought Xia Lin?" Du Lanze teased, "Aren't you afraid of us turning back on our words?"

"I don't know if you will turn back but Ke Mei said that Song Huaixin is not a person who will turn his back." Song Yan said, looking at Song Huaixin, "I hope Ke Mei's guarantee is useful."

Du Lanze curled his lips and murmured something in dissatisfaction.

Song Huaixin said: "I really won't go back on my word but this time, the situation is a bit complicated. I hope you can listen to me patiently next time."

Song Yan nodded and expressed cooperation.

Song Huaixin raised his hand and swiped in the air. A moving image appeared in front of Song Yan. The image showed a concrete schematic diagram of two planes, moving slowly towards each other, the distance between them getting shorter and shorter.

"According to Du Lanze's monitoring data, the contact of the two planes may occur at about 2:15 PM next Friday. Because of the suppression of the upper and lower planes, you can't see anything on the other side's plane. Your ground facilities will be squeezed due to collisions which may cause riots..."

Following Song Huaixin's statement, the image simulates the scenes that may appear during the collision: buildings collapsing, roads are sunken, vehicles are crushed and deformed by invisible forces, and there are countless casualties.

Song Yan closed his eyes and couldn't bear to look at it again.

After a while, he asked in a low voice: "How long will it last?"

"Conservative estimate, about half an hour."

"How about the coordinates? Where is the contact area?"

"Taking your location as the center of the circle, the radius is about 60 kilometers and the longest diameter is about 120 kilometers."

Song Yan was startled: "Why is it centered on me?"

"Because you are the main cause of the spatial displacement," Song Huaixin said, "From the perspective of the entire plane, you are the source of power that changed the trajectory of the plane so your coordinates will become the main gravitational force of contact. "

"In other words, wherever I go is the center of the contact area?"

"No. It's best to use City B as the center because this is the place where you were born and grew up."

Song Yan frowned. City B is a modern metropolis. Once a collision occurs, the damage to the infrastructure and the number of casualties are immeasurable.

"Can the government be notified to evacuate the crowd in advance?"

Du Lanze interrupted: "How can you make the government believe you?"

Song Yan thought for a while, then asked: "What will happen if I change my coordinates to an uninhabited island?"

"As the gravitational imbalance will cause space collisions to intensify, the degree of friction will escalate and the scene will be completely out of control."

Song Yan was silent for a long time and slowly said, "So, what you mean is that if I stay in City B, many people will die. If I don't stay in City B, more people will die?"

Song Huaixin did not deny Song Yan's statement and said: "That's just the worst possibility without my intervention. I can shrink the contact area of ​​the two planes to less than half a kilometer. I can transfer all the pressure caused by the space collision to me and avoid the casualties as much as possible."

It was the first time that Song Yan heard of this method.

He leaned forward and asked, "Well, don't you have to bear a lot of pressure? Will you get hurt?"

"Yes," Song Huaixin said truthfully, "this may consume half of my cultivation base and it will take at least a few hundred years of retreat to recover."

"Hundreds of years?"

Song Yan was stunned. Although he had guessed that Song Huaixin's life span was longer than that of ordinary people, he didn't know it would be that long.

Immediately he felt a little uncomfortable.

"This matter originally had nothing to do with you. Is it worth it for you to do this?"

"It's worth it." Song Huaixin nodded, "This is my duty."

Song Yan suddenly respected him.

But Song Huaixin continued: "Let's talk about Xia Lin again. Xia Lin didn't die of an accident in his previous life. No matter how many times he's reborn, he is destined to not live past twenty-eight. If I will save him, it would be a violation. It is impossible to take care of two things at the same time. If you want to save everyone, you will not be able to save Xia Lin. If you want to save Xia Lin, you will not be able to save everyone."

After Song Huaixin said that, he looked at Song Yan, "If it were you, who would you choose?"
