"Okay, student Fang, you can try it for your principal first."

Zhang Tao said.

In fact, he himself wanted to try it himself.

Because if Jiang Han's anti-bone-tempering method also works on him, then the next situation for mankind will be safer.

But it's a pity.

He is an extremely strong man.

Not to mention the most powerful person, even a golden body warrior and a seventh-grade grandmaster.

Their lives are not entirely their own.

If you want to die fighting in the cave.

Such people need to file a report first.

You can die in battle only if the superiors discuss and agree.

Not to mention the top warriors.

Each one is a strategic nuclear weapon.

It cannot be used lightly.

They cannot easily die in battle, nor can they even be injured.

Just like the riots in the Tiannan Cave.

It's because he sits at the top of Tiannan Cave.

Suddenly, without warning, he entered a forbidden place and died.

The result was a riot in Tiannan Cave.

Humanity has suffered huge losses as a result.

A large number of warriors died in the battle.

In the end, the passage to Tiannan Cave had to be closed.

But this is a temporary solution rather than a permanent solution.

Seal the entrance to the catacombs.

This method can only seal the new cave passage.

Those passages with a certain history, the energy in them gradually stabilizes, and cannot be blocked.

Moreover, the entrance to the catacombs is blocked, and humans cannot enter the catacombs.

Unable to obtain resources in the cave to strengthen myself.

Then humans will become weaker and weaker.

And the catacombs will be fully opened one day.

By that time, humans will really have no power to resist at all.

Therefore, Zhang Tao himself must not be injured easily.

Jiang Han nodded and asked Principal Niu to sit down first.

Then slowly let his own Qi and blood seep through.

This is a good opportunity. Principal Niu is an eighth-grade golden body warrior.

All the bones in the body have been tempered.

Therefore, the bone model in his body is the most perfect bone model.

Jiang Han only needs to look at it once to get all the ten bone tempering model diagrams.

In addition, he also wanted to know whether his own energy and blood could corrode the bones of a master warrior.

Soon, Jiang Han's energy and blood first entered Principal Niu's hand bones.

Fang Han said to Principal Niu: "Principal, the next step of bone tempering may be very painful."

"Don't worry, old cow, am I still afraid of pain?!"

Principal Niu is full of confidence.

As a result, Fang Han's Qi and blood were corroded and entered.

His expression changed instantly.

Numb, numb, itchy.

Like ten thousand ants crawling on him.

No, it’s not on the body, it’s deep inside the body, in the bones, somewhere he can’t even dig at!

"Classmate Fang..., you, didn't you say it hurts?

Why is it so numb and itchy!"

Principal Niu asked.

It's numb and itchy, but not painful.

When Jiang Han heard this, he thought for a while and said, "I helped my classmates temper their bones before, but when I tempered my own bones, I felt severe pain.

It may be because our bones have different strengths and tempering methods.

In the past, when I helped my classmates temper their bones or tempered my own bones, they all felt very smooth.

However, tempering the principal's bones only felt slow, consumed a huge amount of energy and blood, and was not smooth.

This may be the reason why the feeling of bone tempering is different."

Principal Niu could only grit his teeth and persist.

He has the same feeling now.

Uncomfortable.

He is not afraid of pain. Who hasn't had the experience of being hacked several times while fighting in the cave?

This little pain is nothing.

But the numbness and itching were beyond his tolerance.

Four or five hours passed.

Principal Niu's hand bones have finally been tempered.

In an instant, a touch of jade appeared directly.

Principal Niu was stunned.

Zhang Tao next to him was also stunned.

Both of them could feel that Principal Niu's blood strength suddenly increased by a small amount.

"Minister Zhang, my blood seems to have increased by seven to eight hundred calories!"

Principal Niu blinked.

Seven or eight hundred calories.

For this realm, it is not small.

And he has only tempered one hand bone now.

If the whole body is tempered, what will be the result?

It is even possible to directly increase the number of cards by several thousand or tens of thousands.

That is very important to him, an eighth-level warrior.

The more critical point.

By practicing the anti-skeletal tempering method, the qi and blood improved are the basic qi and blood.

If he becomes a ninth-grade warrior in the future and understands the original way.

The basic qi and blood will become even more terrifying after being amplified by the source path.

Zhang Tao walked over and carefully sensed Principal Niu's physical changes with his mental strength.

He soon discovered that there was a touch of jade in the bones of Principal Niu's hand.

He had also seen this kind of jade color and jade bones on Fang Han's body.

But the area is larger.

"Fang Han, Niu Hu, I am giving the order now as the Minister of Education.

Regarding Fang Han helping people practice the anti-skeletal tempering method, no word is allowed to be leaked to the public.

Fang Han, you can no longer help others temper jade bones in private. If necessary, you must report to me!"
