By running this for a week, we can obtain human experimental data on nano-blood within 100 ml.

Moreover, the amount can be increased from small to large, the safety is controllable, and there will not be too much risk.

In the second week, it will be the same running, but the amount of nano blood injected will gradually increase.

The plan will continue until the blood transfusion is 300 ml, and any more will not be appropriate.

In this way, through daily recording, the most suitable injection amount can be obtained.

It is the best dose that allows him to sprint at full strength for 15 minutes without fatigue during night running, and still remain energetic and energetic.

On the first day, because the injection dose was small and he secretly administered it to himself, he could not ask medical students for help.

So he applied for a sample of the company's mini syringe pump.

It is said to be a syringe pump, but it is actually more like a pen.

Just inject the liquid into the disposable needle at the tail, aim the pen tip at the vein, and press the button on the scale to accurately inject the required liquid into the body.

This thing is very convenient to use. Xue Shen knew how to use it as soon as he got started.

He pressed it without letting go, and with a few swish, the scale showed that 1 liter of nano-blood was injected into the vein.

The whole process was like being bitten by an insect, without any pain.

With a gentle press, the injection was completed before any reaction occurred.

Of course, this is mainly due to the small amount, which was only pressed for one second.

If it is 5l or 10l, you need to press for a longer time, and a large amount of liquid is injected into the blood vessels, and it is impossible to feel nothing at all.

After the injection, Xue Shen felt nothing abnormal.

He had already put on his running shoes, so he went to the river as usual, warmed up his lower body a little, and started jogging.

During this period, he ran two or three times a week, so now he is not as tired when running. After his body gets used to the intensity, he can basically recover the next day.

After several rounds of short rests, I finally finished the entire distance in about 30 minutes.

The familiar sweating profusely and body aches were back again, no different from usual.

This time Xue Shen roared happily, washed himself and fell asleep.

Next day, 5l.

Everything is business as usual.

The third day, 10l.

Everything is business as usual.

Day 4, 20l.

Running was the same as before, but he didn't know if it was an illusion. He felt that the soreness after running was not that strong.

The fifth day, 50l.

This time, Xue Shen finally had a clear feeling.

He felt that after running, his breathing became longer and smoother, and he was no longer out of breath like an ox before.

Even the rest time in between has been shortened.

After running 5 kilometers, although I was still sweating, I was not so tired. It seemed that I still had energy left and could run for a while longer.

At the moment, he didn't feel like fighting and went back to the dormitory as usual to wash up and rest.

However, when I woke up the next day, my body's soreness and fatigue were somewhat relieved.

Xue Shen truthfully recorded his physical data and feelings, and felt a surge of joy in his heart.

Day 6, 80l.

This night run was more relaxed than the previous few days.

He ran the same 5 kilometers in one go without needing to rest in the middle.

At the end, although I was still panting, it felt like a normal deep breath and there was no discomfort in my lungs.

I recall when I first started running, my lungs hurt as if they were torn after running for several hundred meters.

Xue Shen instantly felt like he was in another world.

The next day, the pain in my body disappeared. Only by pressing the muscles in my legs would I feel a dull pain.

If you don't touch it, you basically won't feel anything.

On the seventh day, 100 liters of nano-blood was injected into the body through intravenous drip.

A strong expectation suddenly arose in Xue Shen's heart.

He couldn't wait to get to the track by the river, stretched his limbs, and was ready to run.

There were also three or five colleagues standing on the track next to them, all in their early twenties, warming up.

A familiar colleague greeted him warmly.

"Xue Bo, you are running again today. I see you have been running every day recently. Why are you suddenly so interested?"

Xue Shen smiled and waved his hand: "I can't help it. I'm getting older. People in their early 30s should take good care of their bodies. I'm too lazy to go to the gym, so this is the best way. I'll run away now. See you later."

After saying hello, he exerted force on his soles, moved his legs, and his whole body shot out like an arrow from a string.

Seeing his figure quickly disappearing into the distance, the smile on the colleague's face instantly froze.

On the runway, several other colleagues exclaimed.

"Wow, you run so fast!"

"It seems to be Xue Bo. I didn't expect him to be so good at running even though he works in an office."

"No, is it possible to run so fast at night? Aren't you afraid of having a heart attack?"

"The explosive power is very strong, but it will probably slow down soon."

"I bet he won't last long. He will have to rest after running for a minute or two at most."

"Let's go, let's run too."

However, what is surprising is that after they ran behind for at least five or six minutes, Xue Shen was still nowhere to be seen in front of them.

The unconvinced people began to run as fast as they could, each one of them panting like an ox and sweating profusely.

Finally, after running for another seven or eight minutes, I saw the figure jogging at a steady speed in the distance.

Several people looked at each other and were about to use their legs to catch up.

But I heard a person suddenly let out a scream and fell on the spot: "Ah, my leg is cramped~"

"No way, it's so miserable. Hurry, help him to the chair and massage his leg muscles."

Several people hurriedly helped their colleagues aside.

After finally getting rid of the cramped muscles, another five or six minutes passed.

Just about to get up and run again.

Suddenly, Xue Shen ran over from a distance with a leisurely expression, waving his hands and saying hello warmly.

"Hey, why don't you run away? Young people, you have to start running!"

"How can you sit still at this age?"

"Keep running, I'll wait for you in front!"

Xue Shen shouted while exerting force on the soles of his feet, whizzing past like a whirlwind, gradually going away.

A few people were left looking at each other on the roadside.

In this way, after running 5 kilometers in one breath, he came to a chair on the side of the road and sat down without changing his expression or heart.

At this moment, he felt a little hesitant.

After this long run, I seem to still have some energy left, so I am considering whether to run a few more kilometers.

Do you need to increase the difficulty of the experiment? Otherwise, you will not be able to measure the limit value.

Just as I was thinking this, suddenly, a voice sounded in my ears.

"Xue Bo, you are so amazing. You can run for five kilometers without losing breath."

"Have you ever considered running a marathon?"
