In a blink of an eye, more than half a month has passed.

During this period, Chu Xiu would challenge the fifth layer of the Demon Suppression Tower almost every day, but the ghost spider on the fifth layer was too powerful, even if he was already at the ninth order of the Forging Bone Realm, he was far from being the opponent of the ghost spider.

But without points to exchange for demon blood, how could he improve his realm?

Therefore, he could only stay at the ninth order of the Bone Forging Realm, and he didn't break through for more than half a month......

In the past half a month, Chu Xiu did not spare any hands when he participated in the training in order to obtain points to exchange for demon blood breakthrough as soon as possible, and even Zhou Feng had already lost to him.

After defeating Zhou Feng, Chu Xiu deservedly became the strongest person in Class B, except for the perverts in Class A, no one in the entire training camp was his opponent.

But as Chu Xiu's realm stagnated, the rest of Class B had slowly caught up.

After Zhou Feng lost to Chu Xiu, he was practicing almost every night, and his qi and blood had been increased to nine catties and nine taels, as long as he sensed the true qi, he could directly break through to the realm of refining the intestines.

Not only Zhou Feng, but also the other people in Class B have also improved greatly, even Zhang Chen and Sun Shan, their cultivation has also broken through to the seventh order of the Bone Forging Realm, and they have not fallen too far behind Chu Xiu.

Whenever Chu Xiu saw that these people were improving every day, his heart was very uncomfortable, so when he was practicing life and death, he was even more ruthless.

After more than 20 days of life-and-death training, he was stunned and did not lose a single battle.

After so many days of unremitting efforts, he finally got enough 600 points today!

That same evening.

After Chu Xiu exchanged his identity token for a demon blood, he couldn't wait to open the acceleration panel.

[Demon Blood Foundation Building Skill accelerates to the next stage and consumes [30 Silver], is [Demon Blood x1] progressing? 】

Looking at the familiar acceleration panel, Chu Xiu was very excited.

After he took out the exchanged demon blood and thirty taels of silver, he directly shouted "speed up".

Almost the moment he shouted "speed up", the silver and demon blood in his hand disappeared at the same time, and a curtain of light hung down from the void.

The figure walked out of the light curtain, and behind him was a demon clan with a head like a tiger and a body like a cow.

This demon clan is also something that Chu Xiu has never seen, and it should be the same as the cyan birds last time, they are all descendants of the demon clan.

Chu Xiu had already expected this, after all, he exchanged it for the demon blood of the Forging Bone Realm, how could there be the demon blood of the big demon?

When Chu Xiu observed this demon clan, the figure had also begun to cultivate, and he directly used the demon blood foundation building skill to refine this demon clan's descendants into a ball of essence blood, and then absorbed and refined it without hesitation.

As the system accelerated, Chu Xiu's mood also became excited!

He could clearly feel that the human emperor's qi and blood in his body began to surge, reaching ten catties almost instantly.

But when his human emperor's qi and blood reached ten catties, the growth rate of qi and blood completely stopped, and the realm had always stayed in the bone forging realm.

Just when he was wondering in his heart, he felt that there was a trace of warm qi in his elbows, armpits, hips, and popliteals, and these warm qi were the true qi that needed to be perceived to break through the refining realm!

True Qi traveled in the meridians of Chu Xiu's limbs, and the hidden veins in his body that were originally blocked were actually broken through by True Qi in an instant.

As more and more meridians were broken through, the aura on Chu Xiu's body became stronger and stronger, and the true qi in his body became stronger and stronger!

But at this moment, a looming golden chain suddenly appeared on Chu Xiu's limbs.

The aura of this golden chain was very strong, not only suppressing the true qi in Chu Xiu's body, but also locking Chu Xiu's life and soul.

Martial artists in the Refining Realm can live a hundred years longer than ordinary people, but the premise is to break through the shackles of life, and this golden chain is Chu Xiu's first shackles of life!

It is very dangerous to break through the shackles of life, if you do not break through, not only will you fail to break through, but you will also be very seriously injured, and even reduce your lifespan.

Just when Chu Xiu was worried, the true qi in his body suddenly doubled, and directly forcibly broke the golden chain, and Chu Xiu's first life shackles were shattered.

A warm current flowed in Chu Xiu's limbs, and Chu Xiu felt as if his soul had been sublimated at this moment, and the whole person was extremely comfortable.

- Accelerated end.

Hearing the sound of the system, Chu Xiu exhaled a breath of turbidity, and the whole person felt refreshed.

He spread out his right hand, and a transparent ball of true qi suddenly appeared!

Although it was only a small mass of True Qi, Chu Xiu still felt much stronger than the blood qi that he usually broke out.

However, the two are not at the same level, so naturally there is no comparison.

Blood qi is the physical strength of the human body, because of the blessing of the human emperor's qi and blood, the physical body has been greatly improved, so there is blood qi.

If the cultivation of a martial artist is compared to a pool, the improvement of the emperor's qi and blood is expanding the area of this pool, and the blood and qi used on weekdays are just the water in this pool.

True Qi is directly refined from the human emperor's qi and blood, which can greatly increase combat power, and it is not known how many times stronger than blood qi.

However, even if a martial artist refines his true qi, the foundation of his cultivation is still the human emperor's qi and blood.

After all, true qi can only improve combat power, not the cultivation realm, if you want to reach a higher realm, you must have enough human emperor qi and blood.

Moreover, the human emperor's qi and blood are the foundation of true qi, and if there is not enough human emperor's qi and blood, there will never be any improvement in true qi.

Therefore, even if there is already true qi in the Refining Realm, the cultivation of the human emperor's qi and blood cannot be stopped for a moment, and if you want to become stronger, you need to improve more human emperor's qi and blood......

——+Expand to see more useless information+———

The system panel popped up, and after Chu Xiu saw the change in the realm bar, there was a hint of surprise in his eyes.

This time, the acceleration of demon blood foundation building skills actually increased by more than four catties of qi and blood, which was much more than the last time the qi and blood were accelerated.

And in addition to the human emperor's qi and blood, Chu Xiu's dantian also has true qi circling.

Although it was only the size of a child's fist, it made Chu Xiu feel extremely powerful.

Don't know how strong you really are now?

Chu Xiu muttered in his heart, eager to know how powerful his true qi was, and after he cleaned up briefly, he strode towards the courtyard outside the house......
