Professor Wan finished calculating the last formula in his brain before he raised his head and looked at Xi Luo: "Wait, I still have some preparations to complete." ”

"Preparation?"

"Yes. When Professor Convert created the time chip, he also took into account the impact of the chip on different time and space, so he designed a cipher in advance, and only the successful matching of the cipher between the instrument and the chip can activate the ability to travel through time and space. Professor Wan said frankly, "Before he died, Professor Conduit deleted all the memories related to the password in his personal chip. I only found out about it after I became his assistant and participated in the experiment. ”

Xi Luo stared into Professor Wan's eyes and asked slowly, "So...... Do you know what a code is? ”

"yes, I know." Professor Wan nodded, "But I don't want to use the same." Professor Convert has tried to cross six times, but has not been able to save his son, indicating that his experiment has failed. Strictly speaking, I have to learn from this experience to find my own way. ”

"What's that code?"

"There are a lot, and this is the one that impresses me the most. With the laboratory as the center, the total time it takes for Professor Confuge to travel to another time and space is always only eight hours. As soon as the time is up, he will be forcibly taken back to the lab. ”

"If I'm not mistaken, Professor Conversion's son seems to have died in an unexpected upheaval, right? Theoretically, eight hours was enough for him. ”

"But in science, words like 'should' are not allowed. Based on the memories on the chip, I learned that Professor Conversion's son experienced more than a dozen accidents in that short eight hours, including optical brain failure, kidnapping, and loss of important documents, and finally these accidents combined to lead to the irreversible end of death. Professor Wan's voice was cold, as if he was merely stating a failed experiment report.

"After Professor Conversion's chip is embedded in your body, can you have his emotions?"

"No, you can't. The chip only has memories, and superfluous emotions are not necessary. Professor Wan looked at Xi Luo and said lightly, "If you need it, I can copy the memories of Professor Confuge through time and space to you." Remember to destroy it after reading it. ”

"Yes."

"Alright, it's time for you to leave." Professor Wan began to rush people, "I need to think in a quiet enough environment, any distractions may cause errors in the experiment." ”

Xi Luo had no choice but to take Professor Wan's copied chip and go outside. She really wanted to know what had happened to Professor Confuge during those eight hours, but that didn't mean she was just curious.

However, she was kicked out by Professor Wan just like that......

By the time Xi Luo arrived at the nearest chip reading place of the Passing Star, it was already four hours later.

The memory copied by the chip is very clear, and the conversion professor that Professor Wan imitated through the chip is almost exactly the same as himself in appearance, except for the slight difference in his eyes.

The real professor can already feel the breath of old age, but Professor Wan looks like a middle-aged man.

……

The first crossing was successful.

Professor Conversion's expression was excited, as if with a thousand words in his heart, he strode to the nearby communication office, called his son, and told him that he could not go to a certain place in eight hours under any circumstances, otherwise he would be in danger of his life.

Although the son was a little surprised, he still obediently agreed. Professor Convert sat down on the steps and waited for eight hours, as if he couldn't feel the rain in the sky.

Finally, when the eight hours were approaching, when Professor Convert called his son again, there was no answer; The more he thought about it, the more frightened he became, and he almost frantically ran to the place where his son would die in the future.

It was still a step too late, and he could only watch his son fall to the ground covered in blood, while he himself turned into a white light and disappeared into this time and space, unable to even shout 'save people'.

As soon as Professor Conversion, whose eyes were red, returned to the laboratory, he immediately began to prepare for the second experiment. As an assistant, Professor Wan came over several times to persuade him to rest and continue, but Professor Wan refused, and said in his mouth: It's too late, it's too late.

The second time travel.

Professor Conversion really couldn't figure out why his son, who had always been filial, didn't listen to him. So, he made the crazy decision that he was going to kidnap his son until the end of the turmoil.

He knew that he was not an opponent as the son of a soldier, so he could only use the kidnapping of himself to scare his son into coming to look for someone, and take the opportunity to stun people with reagents.

Professor Conduit thought that he could rest assured this time, but he did not expect that he would be counterattacked by his vigilant son and knocked unconscious with a stick; When he woke up, he was already in prison, and he was anxious to explain that he wanted to escape, but no one paid any attention to him.

It wasn't until more than seven hours later that the prison guards received an urgent message of condolence......

Traumatized, Professor Convert passed out and soon the white light took him away again.

Before the third crossing.

Professor Jian silently told himself in his heart that he must not be so reckless this time, and that he must be fully prepared to set off.

This time, he decided to outwit and steal important materials from the military department through high-tech means, and told his son that he had to come and pick up things within a certain period of time.

Professor Conduit waited at the agreed place for five hours, but his son still didn't come, so he made a mess and began to communicate desperately.

The situation was out of control again, and Professor Kan was so anxious that his fingers were trembling, and he kept hinting to himself in his heart: it would be too late, it must be too late.

Professor Convert ran to the place where his son died in a car, but he encountered the scene of the car accident in front of him, and he couldn't walk there at all. Professor Convert leaned his head weakly on the seat of the car, and after a long time, he slowly raised his head, as if he had made up his mind.

The fourth crossing.

This time, Professor Jian used the virus to invade his son's optical brain in advance, secretly installed the positioning software, and did nothing else.

He followed the surveillance system, carefully remembering every location his son had visited during the eight hours, and remembering the key moments.

Subsequently, Professor Kan watched with his own eyes how his son was little by little involved in the turmoil, and finally affected to the point of losing his life.

He hadn't done anything until eight hours later, when he was recalled to the lab.

Fifth crossing.

Professor Conversion, much calmer than any time before, tried to get to the source of the turmoil, with the idea that he would rather sacrifice himself to end the riot.

In the end, he was captured by the enemy leader, and his son had to change his route to the turmoil zone in order to save him.

……

The sixth crossing.

Professor Kan stood in the street at a loss, confused and unsure of what else he could do.

When he designed the crossing rules, he planned for such an extra one. It is absolutely impossible for the same person in the same time and space to meet, which means that he has no way to change any of his behavior.

After eight hours of numbness, Professor Kan opened his eyes in the lab, and the person he saw was his assistant.

"Teacher, are you alright? Is this backlash serious? Professor Wan asked a little nervously.

Professor Conversion's eyes were red, and finally tears fell desperately: "I'm sorry, I'm sorry, I really can't stand it." ”

Professor Wan didn't seem to understand the teacher's current behavior, and he couldn't analyze what had happened to his teacher.
