Yunci gets up from the ground and wants to rush through, but finds her legs become transparent. No matter how hard she tries, she can't take a step. At the same time, the picture in front of her begins to split.

When she opened her eyes again, she found herself sitting on the chair of the time machine, with the former doctor standing by.

She's back

Think of Gu Jingwen was knocked down by the billboard that scene, cloud words instantly red eyes, her eyes as sharp as a blade, straight shot to the original doctor: "why... Why not!"

The first time can be interpreted as an accident. What about the second time?

Dr. yuan seemed to have known for a long time that this would be the case. He lamented, "I said, you can't save it!"

Yunci directly took off his helmet, got up and approached Dr. yuan with two steps: "speak clearly!"

"Well, this..." Dr. yuan organized the language for a while and asked, "do you know the grandmother paradox?"

"I don't know."

Dr. yuan seriously explained to Yunci: "in the academic circles studying time travel, he once put forward such a hypothesis. If a person goes through the past and kills a pregnant woman, the woman is actually his grandmother. His grandmother is pregnant with his grandmother. He kills the woman. If his grandmother dies, there will be no grandmother, There would be no mother. Without a mother, he would not exist.

If he does not exist, his grandmother will not die, and will give birth to his grandmother smoothly. His grandmother will give birth to his mother again, and his mother will give birth to him. In this way, he will exist again, pass through the past by chance, and kill his grandmother. His grandmother and his mother, including him, will become nonexistent again. His existence will result in his own non existence, and his non existence will form his own existence, which is contradictory.

So, you can go through the past, but you can't kill the people who should be alive, and you can't save the people who have already died. "

Can't save

Time machine in front of her, she can even really go back to the past, but now tell her, can't save? She can only watch Gu Jingwen die again and again?

The fire of hope, which should have been ignited, seems to be burning and swallowing Yunci. However, she is cold from head to foot, as if her blood is frozen. In front of her eyes are the ashes, the darkness is overwhelming, and she can't find a bright exit.

"Impossible..." Yunci suddenly rushed to the former doctor, grabbed his collar with his hand, and let out a shrill roar from his throat: "if you can't save people, if nothing can be changed, what's the use of building this time machine!"

Dr. yuan's face turned white with fright. He replied with trembling: "I... I built this time machine in the hope that people can go back to the past, fulfill their unfulfilled wishes, make up for their regrets, meet people they haven't had time to see, and help people understand the history and civilization of the earth..."

Yunci's eyes were red and her mood gradually recovered. She suddenly released her hand, stepped back two steps, and rubbed her sour brow.

Yeah... It's amazing that he can create a time machine. How can he ensure that he can save people?

"Let me try again." The voice of Yunci is feeble.

"No, no, you've tried twice!" Dr. yuan shook his head.

Seeing that he refused, Yunci suddenly lifted the chair next to him and pointed it at the time machine, threatening: "if you don't let me try, I'll smash it."

The original doctor immediately panicked, this is his painstaking work!

"No, no, no!" Dr. yuan was so scared that he was sweating all over his head that he quickly made a voice to stop him: "calm down, calm down! I can't promise. Put the chair down quickly
