A bottle of Bigu Dan turned around, exactly one person and one grain.

This thing is just a belly-sized black ball, which doesn't smell fragrant at all, but has a medicinal smell.

But there was something in the stomach, and everyone was a little more energetic.

Su Zimu didn't taste anything, it was like chewing a piece of chewing gum in his mouth, but the effect was immediate, and he didn't feel hungry immediately.

Yes, yes, this thing is equivalent to a monk's exclusive compressed biscuit, and you must reserve a little more emergency when you go back!

The energy was replenished, and Su Zimu couldn't wait to continue his practice.

Along the way, he had already strengthened his muscles and bones several times, and now he decided to give priority to strengthening his skin and fully protecting himself with the strongest skin armor.

There are no dead ends in all directions, and there are no loopholes in the body all day long!

Just ask, who else!

When the strengthening begins, the skin slowly tightens like a heated film where the heat flows, and the strength increases.

Although Su Zimu had reduced the heat flow to the weakest, when it was condensed, it was like tearing off the skin on his body alive.

When he strengthened the skin of his whole body, it was like wearing a super-tight restraint suit, and his whole body was tense, and he felt like he was about to tear his skin when he moved.

Fortunately, after the skin is strengthened, the resilience is greatly improved, and after waiting patiently for a while, the tightness will relieve itself and gradually return to normal.

Then came another round of reinforcement.

After a few rounds of repetition, the skin of Su Zimu's whole body became extremely tough, strangling his whole body like a cowhide made of nitrate.

This time, after waiting for a long time, it didn't work, and even began to compress the muscles, and even the blood circulation was not smooth.

Su Zimu gradually realized that the problem was wrong, and immediately began to strengthen his muscles.

The heat flowed, and wherever he went, the sharp pain followed, and after a cycle, the pain that almost made people faint ran through the whole body, like being trampled under the feet of an elephant, and then crushed a few times; It's like having hundreds of saw blades cutting the whole body at the same time.

He didn't know what the orthodox five-tone forging body felt like, but this strengthening method on his body was too painful.

Su Zimu almost crushed his mouth full of back molars, and finally persevered until the end of the reinforcement, and the whole person collapsed, and it took a while to slow down.

At this moment, he had only one thought in his heart: this is really not a practice that people should practice!

Ling Chi was executed, but that's it!

But the problem was not solved, and he made a long mental preparation before he made up his mind to start another round of strengthening.

By midnight, the muscles and skin have finally reached a new balance.

Su Zimu didn't figure it out until this time, it turned out that the strengthening order of muscles and bones first and then skin and flesh made sense.

From the inside out, layer by layer.

The reverse is different, the flesh is strong but the muscles and bones are weak, which is equivalent to building a skyscraper, but the use of seriously substandard steel bars results in a slight movement, and several bones will be broken.

Thinking of this, Su Zimu was afraid for a while.

It's really dangerous to practice this thing, and if you're not careful, you bury yourself in a pit, or dig a pit yourself.

The skin, flesh, muscles and bones are all finished, and it is still early to see the time, Su Zimu has done psychological construction for a while, and finally decided to strengthen the internal organs.

Worried that he would not be able to bear the reinforcement at the same time, he chose to do it alone to weaken the pain.

However, the internal organs are different from the skin, flesh, muscles and bones, and some organs are not sensitive to pain, but they feel uncomfortable, and they pass without feeling; Some organs were just the opposite, the heat flow was only slightly touched, and the shuddering pain exploded instantly, and the pain made him tremble all over, and he couldn't control it at all.

Su Zimu was also ruthless, only when this body was not his own, he fainted in pain several times during the period, but after waking up, the first thing was to continue to strengthen.

The edge of the sword is sharpened, and the fragrance of plum blossoms comes from the bitter cold!

The liver, intestines, spleen, stomach and kidneys go through one by one, and the pain nerves have begun to numb

But Su Zimu didn't dare to be careless, because the next step to strengthen the organ is the engine of the human body - the heart!

It was so important that Su Zimu concentrated all his energy, controlling a trace of heat flow close to his heart.

However, as soon as there was the slightest contact, the heart immediately became disordered and convulsed, and the blood circulation throughout the body was immediately chaotic.

Su Zimu's soul was about to fly away, and he didn't have time to think about it at the critical moment, so he suddenly strengthened the heat flow and gave his heart a ruthless blow.

The spasmodic heart stopped beating on the spot.

Su Zimu's eyes darkened: It's over!

His brain went blank, thinking that he was going to die, and was about to rush to give his heart another hard blow before consciousness disappeared, and the stiff heart muscle suddenly contracted inward, and then the atria and ventricles rhythmized in turn, quickly returning to normal.

After being stunned for a while, the frightened Su Zimu let out a long breath.

It's terrifying!

However, the temptation just now also made him clear one thing, that is, although the heat flow is not a real electric current, it has the same effect as an electric current.

Therefore, the sudden strengthening of heat flow just now is actually the same as electric shock pacing, and fortunately it worked, otherwise this little life would have been completely confessed.

Thinking about it carefully, Su Zimu couldn't help but be afraid for a while, it was only less than a day, and he had already turned around a few times outside the Ghost Gate?

This technique is too special, isn't it?

No wonder no one wants to forge their bodies.

However, when I think about it, I am relieved.

Cultivating bamboo is to go against the sky, and other monks either have the support of the same path, or have a complete mental method, so they can naturally follow the steps step by step and step by step.

And what about him?

The orthodox five-tone forging body strengthens itself with high-frequency vibration, but when it comes to him, it becomes an improved version of the Heavenly Tribulation.

That is, he was lucky to pick up a small life, otherwise he would have died a few times.

Take 10,000 steps back and say, looking at the cultivation world, someone like him who dared to attack the heart just after knowing how to strengthen the body, really couldn't find a second one.

Su Zimu really didn't want to continue to strengthen the heart, but the other organs were strengthened, but the heart was left alone, which was not only a shortcoming, but also the biggest weakness!

As the old saying goes, a person's height is not in how long his strengths are, but in how short his weaknesses are!

After hesitating again and again, Su Zimu finally made up his mind: since he had come to this point, he could only continue to walk.

He did not act rashly, but, after careful consideration, decided to divide the heart into several parts, which were strengthened separately with weaker heat flows.

If some of the heart muscle is stiff, it will return to normal with the help of other normal heart muscles.

But when it came to the end, he hesitated again, in case of another problem, he might not be as lucky as before!

After thinking about it for a moment, he came up with the idea of compressing his heart with his chest muscles to restore his heartbeat.

Strengthened muscles, should be fine, right?

But after trying several times, it didn't work as well as it should.

The new protocol is stillborn

Then, he thought of a way to stimulate the musculoskeletal muscles near the heart with a stream of heat, which was indirectly strengthened by vibration.

This is also the orthodox means of the five-tone forging body.

This time it was successful, but the effect was too poor.

Several plans were unsuccessful, and Su Zimu was a little embarrassed.

He always believed that the heart could be strengthened, but he didn't find the right way...... By the way, the heartbeat is controlled by bioelectricity, is this something that can be used?
