When Zhang Fan saw this, his heart was moved, and his eyes were extremely hot.

One second in the Overworld is equivalent to one minute in sub-biological space.

This means that as long as you can successfully build a sub-biological space, you can have 60 times as long as the average person.

Isn't this what I need most urgently?

Zhang Fan's fists clenched involuntarily, and the speed of his heart beating accelerated a few points.

Sub-biological space, you must make it!

He immediately turned off his nanowatch and walked towards the dormitory.

There is surveillance in the classroom, and if they are seen, God knows how many people will pounce.

When he returned to the dormitory, Zhang Fan's palms were a little damp because of his excitement.

He turned on the nanowatch again and looked down.

After a while, I finally finished reading it.

He understood.

To build this biological space, three points are needed.

First of all, it requires the hand speed of being single for 100,000 years.

For this, Zhang Fan is very confident.

With the speed at which he drew his sword, there was absolutely no problem.

Secondly, it requires a strong sense of perception and can detect subtle changes in anything.

For example, when two mosquitoes are five meters away, what position is used, you can find out clearly.

This one is a bit harder.

I'm afraid that only a high-level or even a peak martial artist can do it.

However, it is also said in the video that if you can get a perception enhancement potion, you can greatly enhance your perception ability.

Looks like we'll have to hurry up and check to see where we can get the potion.

Finally, it is necessary to use energy stones as an energy source to support the energy consumed in the space of sub-organisms.

The power stone Zhang Fan knew that it was an extremely rare stone.

There is an unimaginable amount of energy inside.

Generally, after reaching the martial arts, if you want to be promoted, the energy required is unimaginable.

If you want to improve your cultivation just by cultivating, it is almost impossible.

Therefore, you need the assistance of the energy stone, and through cultivation, you can absorb the energy in the energy stone.

And because the energy stones are extremely rare, the energy contained in them is extremely majestic.

Therefore, the price of energy stones is extremely terrifying.

The price of a power stone has reached at least 3 billion.

That's it, there's no market.

Because ordinary martial artists, no matter how poor they are, they will not sell the energy stones that are closely related to their cultivation.

Only ordinary people who occasionally get power stones will sell them.

However, the probability of ordinary people getting energy stones is lower than that of 50 million.

As a result, it is almost impossible to find gemstones on the market.

Once one appears, it will immediately cause a rush, which will cause the price to be greatly raised.

It will often exceed 5 billion!

This sounds too exaggerated, but for a martial artist, nothing is more important than the improvement of strength.

Because after reaching the martial arts, every time you raise a small level, your lifespan will also be extended by 50 years.

Spending 5 billion to buy a 50-year lifespan is a bargain for warriors.

But for the current Zhang Fan, 5 billion, this is an astronomical amount.

I thought that I was already very rich with more than 200 million, but compared to this power stone, I was still poor.

Looks like he's going to have to find a way to make more money.

After watching the video, Zhang Fanqiang pressed the excitement in his heart and continued to practice the golden body technique.

This practice is five hours.

He was practicing when others were eating, and he was still practicing when others were sleeping.

Five hours later, he stopped sweating profusely and panting.

Just as he was about to get up to drink water, he suddenly felt a sharp pain under the third rib on his left side.

It hurt so much that he almost lost consciousness.

"Damn!"

Zhang Fan scolded and took a deep breath.

Then he spit out a long way.

What's going on?

It stands to reason that the body of a warrior generally does not show the symptoms of ordinary people.

I haven't been seriously injured lately.

Even if you have an injury, your body has the ability to heal itself, and you can heal in a short time.

How can there be a sudden severe pain in the body?

Could it be that there is a problem when cultivating the Golden Body Technique?

If that's the case, then you'll have to go to the martial doctor.

A martial artist is a doctor who specializes in treating cultivators.

Since cultivators do not exhibit the symptoms of ordinary people.

If there is a problem in them, it is basically due to cultivation and fighting.

Therefore, there are doctors who specialize in treating cultivators, called martial artists.

The status of martial artists is generally very noble, and the cost of treatment is naturally very expensive.

Although Zhang Fan has more than 200 million, it is not enough to buy a power stone, how can he have spare money to see any diseases?

However, if you don't see a doctor, your injuries will only get worse.

In desperation, he had to sigh and plan to call the number of the martial arts doctor stationed in the academy.

However, when I opened the desktop of the nano watch, I inadvertently swept to an icon on the desktop: Health Secretary.

This health secretary, Zhang Fan has tried before, is a software that can diagnose and propose treatment options.

This kind of software is basically available to ordinary doctors in the safe zone now.

However, this kind of software can only diagnose ordinary people.

And those warriors, because their bodies have been greatly strengthened, and the degree of reinforcement is different for each person, the body data is completely different.

Therefore, this kind of software cannot diagnose the warrior.

If a martial artist has a physical problem, he still has to find a martial artist.

Zhang Fan sighed.

If only this health secretary could diagnose the warrior.

He was troubled, and he was angry and nodded at the health secretary.

Soon, a green light appeared on the nano watch, and this light was fan-shaped, sweeping Zhang Fan up and down twice.

The next moment, a three-dimensional simulation of Zhang Fan's body appeared on the interface.

On the mockup, under the rib cage on the left side, there is a red dot.

Annotate with text next to it:

Cause: Excessive cultivation of the Golden Body Technique, resulting in occlusion of the left subcostal meridian.

Treatment Options:

1. Stop the cultivation of the Golden Body Technique, and it can be restored in three days;

2. Buy recovery medicine, half an hour after taking it, you can recover;

3. The left fist is at a forty-five degree angle, and three consecutive punches are bombarded to the left front, and it recovers immediately.

"Uh......"

Zhang Fan saw these solutions, and the first two were okay.

Why is this third one so unreliable?

However, the first time was too long, and it was impossible for him to stop cultivating the Golden Body Technique;

The second costs money.

Recovery potions are also very expensive.

Didn't you see that Lao Tzu was short of money?

There is only a third one, which not only does not cost money, but also takes a short time.

And it's simple, convenient and easy to operate.

Thinking of this, Zhang Fan immediately clenched his left fist, then found the right angle, and used all his strength to blast towards the upper left forty-five degree angle.

"Heh-heh-heh-"

Three punches in a row.

After three punches, Zhang Fan suddenly felt that the pain under the rib cage on his left side had completely disappeared.

And there was a sense of relief all over my body, as if the pain had never been there.

Zhang Fan looked at his body, and then looked at the health secretary icon on the multi-function watch.

"I'll it! This...... That's amazing, isn't it? ”

At the same time, Zhang Fan's heart was also alive.

Hey, a chance to make a fortune!
