Just like the martial arts practiced externally, the martial arts practiced internally also derives its strength from other sources.

Different inner martial arts obtain energy from different weird spaces, so the effects and side effects are also different.

Lin Qianxing was thinking that the people who first created martial arts may have inadvertently sensed these strange spaces, and then left the key to draw energy from them through mental methods, so that those who came after them could directly use it during practice.

the energy in it.

This is probably the essence of the martial arts practice in this world.

Of course, it does not rule out that the energy absorbed by that mental method comes from a specific weird existence.

Just like those visualization pictures.

Lin Qianxing has been reborn many times, and his talent in martial arts is naturally extraordinary.

Ordinary people practice martial arts and absorb the energy of heaven and earth one by one.

But Lin Qianxing practices the "Life Extension Kung Fu" and obtains energy from that strange space by directly swallowing it like crazy.

In three days, he filled all 720 acupuncture points in his body with the gray-green life-extending inner energy.

Lin Qianxing didn't know if he was the first person to do this, but he thought that others would not dare or be able to play like him.

For ordinary practitioners, it is extremely difficult to fill a single acupuncture point. What's more, if the body is not strong enough and there are many acupuncture points around the body used to carry the inner energy, it will easily kill oneself.

That is to say, Lin Qianxing has the level of external training at the Grand Master level, and his body has become extremely tough after being reborn so many times. Otherwise, he would not be able to achieve this level easily.

As the 720 acupoints all over his body were filled with the life-extending Qi, Lin Qianxing's thoughts moved, and the 720 acupoints all over his body started to rotate at the same time, and in the process, he continued to use his mind.

At a certain moment, his acupoints established a stable connection with the strange space. The rotating cyclone actively drew strands of energy from it. Although it was not as fast as Lin Qianxing's active absorption, it was better than the endless supply.

At the same time, liquefied internal energy began to appear in Lin Qianxing's 720 acupuncture points.

Not long after, the space in his acupoint that had been filled suddenly became empty again, leaving only the drops of liquid internal energy lying in it.

Lin Qianxing has now entered the second realm of internal martial arts training, the Condensation Realm.

Feeling the 720 cyclones around him constantly rotating, Lin Qianxing showed a satisfied look.

Even if this life-extending inner energy is lacking in combat, as long as the quantity can keep up and Lin Qianxing develops it a little, he can easily use it later.

However, the issue of accelerated aging really needs attention.

Lin Qianxing looked at his obviously mature face in the mirror and felt a little emotional.

He was only fifteen years old at this time, but he already looked twenty years old.

You know, he has been reborn so many times.

In other words, his lifespan and so on have also been improved.

He is now twenty years old, which is almost equivalent to an ordinary person being over a hundred years old.

Of course, he practiced 720 acupoints at the same time, so it is normal for the side effects to be obvious.
