Prologue [Crossing must also have insurance]

"We can't change history because we can't go back to ...... past."

Dr. Ma muttered to himself that it was the first sentence of a paper he wrote last year, and he remembers that he was almost disqualified from teaching because of the paper on time travel. Of course! His arrogant and arrogant personality is also an important reason why he is not liked by the teachers and students of the school, if it were not for the strong recommendation of Director Liu of the Department of Medicine, he would have joined the army of graduate job seekers. Those who knew about it thought he was delusional, and some people had advised him to see a psychiatric doctor, which was clearly a satire on his psychological problems.

"Shhh......h

Ma Yun tried his best to open the curtain in front of him, looked at the machine in front of him and laughed, and said: "You are all laughing at me, no one can understand me, I want you to see, you are all wrong, time and space travel is okay, as long as you have my time machine, you can not only go back to the past, but also go to the future." ”

Ma Yun unscrewed a plastic bottle on the table and took a sip, the bottle is a precious sample he asked from Director Liu of the Department of Medicine, it is said that after taking it, it can change the body's physical performance genes and make people physically strong, the development of this basic factor has just made progress, and the specific effect has not yet been clinically tested.

Ma Yun knows that time travel is very demanding on the body, and it is undoubtedly very dangerous to use his thin body to travel time and space, so he is willing to act as Director Liu's "guinea pig".

The time machine is not big, in addition to the basic factors of the bottle, Ma Yun carries only a holographic DV camera and a self-defense saber, he must use the camera to record what he has seen, as evidence to prove to the world that he has indeed returned to the past or the future, and then push this time machine to the foreground, and wait for that time, to see who dares to mock him.

The future is unknowable and full of uncertain dangers, so Ma Yun set the time in 260 BC, he had long thought that only by recording the most shocking things can the world be convinced, so he chose the incident of Qin General Bai Qikeng killing 400,000 Zhao Guo soldiers, and the scene of 400,000 people being killed will definitely be suffocating.

Ma Yun sat down in the time machine after setting the round-trip time, his hand trembled a little after touching the switch, all the efforts are about to come to fruition now, and he can't tell what it feels like in his heart.

Ma Yunya bit his teeth, his heart was horizontal, and he flipped the switch hard.

The scene began to change as soon as the humming sound sounded, and he knew that the time machine was in motion, and that everything would be clear when the machine stopped.

A time tunnel was formed during the operation of the time machine, and the colors seen in the tunnel could not be described in words, and Ma felt that it was the most beautiful color he had ever seen in his life.

When the time machine stopped, Ma Yun cautiously walked out of the machine, looking at everything he saw with curious eyes, just when he wanted to let out some emotion, he suddenly heard the sound of horses' hooves behind him, and when he turned around, he was greeted by two bigger and bigger horses' hooves.

When the horse's hooves made very close contact with Ma Yun's head, he had millions of unwillingness in his heart, and he didn't believe that he would end up like this - his head was crushed by the horse's hooves.

Zhao Kuo was as stupid, he rode a horse and galloped on the grass on the bank of the Zhanghe River, when a person suddenly appeared out of thin air in front of him, and he couldn't collect the horse and knock the person away, and he also flew forward.

Alert ...... Alert...... If the battery is abnormal due to overload, a particle explosion may occur and the space-time ...... will be shaken again. ”

Before Zhao Kuo could figure out where the voice came from, he saw a white light light next to him, and then he didn't know anything.
