Looking at Chen Heng, Kelly deeply breathed in. He could only calm down his emotions after a long while.

Fortunately, Chen Heng was his friend.

​​

They had spent a lot of time together now, and there was a certain degree of trust between them.

With this relationship, the further Chen Heng went in the future, the better it would be for him.

If Chen Heng could really reach this state, even his family would value him more and provide him with more resources.

Thinking to there, Kelly could not help but smile, and his expression looking at Chen Heng became even more fervent.

Looking at Kellys' reaction, Chen Heng inwardly smiled.

Long ago, he had imagined Kelly and the others' reactions.

The reaction that Kelly gave was what he wanted.

Now, Chen Heng had already shown his value. If others could see this, they would invest more in him and help him more, which would boost his growth.

As they invested more in him, when they reached a certain point, even if they wanted to give up on him, they would not want to take the loss.

After all, they would have already invested so much, and if they gave up on him, all of that would have been for nothing.

Chen Heng deeply understood this.

As expected, on the way back, Kelly spoke about some things in the Kutu Royal City, and he bought some stock from shops owned by Chen Heng at very good prices, allowing Chen Heng to earn some extra money.

Following this, Chen Heng returned to his own residence.

A few days later, during the early morning, the sun was already shining brightly.

Chen Heng stood by himself on his residence's training ground. His expression was calm as he silently stood there.

"Cultivating both inside and out, circulating one's qi blood…"

As Chen Heng silently cultivated the Body Forging Technique, he thought to himself, "The Solid Rock Body Forging Technique is one that circulates qi blood. It seems that doing this can also affect the circulation of life energy…

"Based on this, it seems that the so-called Life Energy is most likely part of the body's qi blood; it's just a bit special…"

Recently, Chen Heng's Knight training had reached a bottleneck, so he had focused on the Solid Rock Body Forging Technique.

According to the records from the Solid Rock Body Forging Technique, this Body Forging Technique came from Master Panshi, who had killed and observed a Stone Demon's body composition, turning it into a Body Forging Technique.

If ordinary people wanted to learn this Body Forging Technique, they had to first reach Body Forging Completion and then circulate their qi blood, cultivating both inside and out, turning one's body into a solid rock.

The entire Body Forging Technique, from the preliminary Body of Flesh and Blood to the final Solid Rock Body, could be split into three steps.

The first step was to refine one's body to the point that it could resist sabers and swords.

Once one reached this step, even though one would look the same as an ordinary person, one could transform one's body to a point that one could resist sabers and swords after circulating one's qi blood.

Following this, the next step was to condense their qi blood and turn their body into a Solid Rock Body.

Once they formed their Solid Rock Body, they would supersede the Body Forging level and reach the Martial Body Realm.

At this level, those with Solid Rock Bodies would not be injured by sabers and swords at all once they circulated their qi blood.

From the description, it seemed that even smaller guns would not be able to break through the Solid Rock Body.

That was the second step.

After condensing the Solid Rock Body, the final step was to condense the Solid Rock Heart, completing the Solid Rock Body.

Upon reaching this step, one's Solid Rock Body would be complete, as would one's Martial Body.

According to Chen Heng's understanding, in the real world, martial artists of this level were no ordinary people. Even in the entire Lin City, they would be quite an impressive figure.

Of course, Chen Heng was still far away from this step.

He was currently still on the first step, refining his body and qi blood.

He went through this step incredibly slowly and with great caution.

There was no way around it.

For most people, when they did body forging, they would have seniors or teachers watching over them.

However, Chen Heng did not have something like this.

Body forging was incredibly intricate, and if even one small detail went wrong, it could result in big problems in one's body forging. It could cause future problems, causing some devastating results.

As such, Chen Heng was extremely cautious as he went through the body forging process.

However, he discovered something while cultivating.

When cultivating the Solid Rock Body Forging Technique and circulating his qi blood, it would also cause his life energy to circulate.

With his life energy joining in the process, the effects seemed to be better than just purely refining his qi blood.

This made Chen Heng feel quite surprised.

It seemed that Knights' life energy was quite similar to martial artists' qi blood; they were just treated differently.

As such, a Body Forging Technique that could circulate one's qi blood also had effects on life energy.

With his life energy helping, even though Chen Heng cultivated the Solid Rock Body Forging Technique quite slowly and cautiously, his progress was not slow at all.

Almost every day, he could sense his progress and feel his body gradually becoming stronger.

Honestly speaking, it felt amazing.

However, because he was limited by the amount of life energy his body had, he could not cultivate the Body Forging Technique every day for very long.

This restriction greatly restricted Chen Heng's progress speed, making things much slower for him.

Of course, Chen Heng already had some ideas about how to get around this problem.

It actually wasn't too difficult to solve this problem.

Since he didn't have enough life energy, he just had to find ways to increase his life energy.

Increasing one's life energy was not too difficult either.

In this world, those who went through Knight training would often consume some medicines.

The function of those medicines was quite simple, which was to ignite one's lifeforce to produce more life energy.

Back during Chen Heng's first simulation, he had obtained something like this from Sorodon before.

Now, as Corripo's student, it was not difficult for him to obtain things like this.

Of course, for ordinary people, these things could not be used too much.

Igniting lifeforce was essentially igniting one's qi blood, allowing one to produce more life energy.

Igniting lifeforce like this once or twice was fine, and even though it was not good for the body, it was still within a recoverable range.

However, if one did this for a prolonged time, it would cause great harm to one's body. In fact, it could even affect their lifespan.

The cost was quite great.

As such, apart from some people who were beginning Knight training, most people would not use such a thing.

However, the methods that other people did not want to use were very suitable for Chen Heng.

Using this sort of thing, he could ignite his qi blood and lifeforce to produce life energy, solving his issue of lacking life energy.

As for the reduction in lifespan and other problems…

Chen Heng thought about it and did not feel that there was much of a problem.

After all, this was not his real body and whether he lived long or not did not matter.

Moreover, from how chaotic this world was, even if he did not do this, it was unlikely he would die of old age.

As such, it was better to sacrifice some of his lifespan to increase his strength as quickly as possible.
