For a while, a seven-colored storm was set off in the cultivation secret room......

Colorful light, as the boiling blood entered his throat, emanated from Duan Lie's involuntarily condensed Dou Qi armor, and soon illuminated the gloomy cultivation secret room as bright as day.

The boiling hot blood was tumbling in the veins of his body, and the boiling fighting qi was like a tsunami, and Duan Lie's nerves instantly tensed.

In stark contrast to the previous seven months of silence and blandness, his body was under tremendous pressure......

This pressure comes from the boiling of the fighting qi in the body, which is increased by up to ten times, and this is the effect of boiling blood.

Raise the fighting qi tenfold, like copying the meridians and the sea of qi, and then absorb and refine frantically within five minutes, how much can be absorbed depends on the individual's physical fitness, the fighter at this time, Duan Lie at this time needs a strong heart to drive the tension of the bloodline, and do his best to make the fighting qi spread all over the body, and finally return to the battle spirit.

Of course, this process requires a lot of waste, and the colorful light presented on the surface of his body is because the fighting qi suddenly rises too much to contain and carry the leakage after it. And in this process, the squeezing and penetration that the body will endure is very terrifying.

So Duan Lie drank the bottle of strong heart......

The strong heart can be deployed by using the powerful heart of any Warcraft, and a small piece can achieve considerable results, but because of the different levels and bloodlines of the Warcraft, the quality of the strong heart after it is deployed is also good and bad.

Of course, within his powerful god-level pharmacist realm, he would not look at the strong heart more, and he could mix more good things, not to mention a bottle of excellent quality holy medicine.

However, no matter how powerful a pharmacist is, he doesn't have an intuitive feeling before taking a certain potion, so after Duan Lie drank two bottles of potion, beads of sweat fell directly.

"This ...... Is it boiling blood? It's really strong enough......" Duan Lie clenched his teeth, and there was a cold wind with severe pain between his teeth, no way, the strength of the boiling blood was directly more than ten times that of the fanatic potion, and it was still very difficult to bear it with his small physique, if it weren't for the existence of a strong heart that improved his physical fitness, I am afraid that in a minute, he would be able to meet God.

Five minutes.

Duan Lie gritted his teeth and insisted desperately, at the same time, he also had to urge the Empty Void Qi Cultivation Technique to make the boiling Dou Qi active in the meridians, and the more so, the greater the pressure he was under, the surging tsunami-like Dou Qi was like a sharp long sword, piercing his muscles, and the real pain had to last for four minutes, Duan Lie almost fainted.

Time seemed to be about to stand still, second by second, like stingy free water dripping from a faucet that had been turned off for most of the time, Duan Lie clutched his palms and bleed, but the severe pain did not understand his suffering, and it intensified as before.

"Boom, boom!"

Soon, he heard the roar of the tide, and in the spiritual world, the sea water continued to rush to the island on the other side, which was the only land in the entire sea, and a humanoid luminous body trembled violently in the continuous surging tide......

The seven-colored light swarmed, constantly infiltrating and infiltrating, and gradually, Duan Lie felt that his battle spirit was about to more than double.

However, he knew that this was far from enough, and if the five points of medicinal power could not be fully absorbed, there would be no benefit except to create more pressure and burden on his body.

The real effect is all in the essence refined during the reincarnation of the Empty Qi Cultivation Technique, the harder he works, the more Dou Qi the Battle Spirit can absorb, just like accumulation, he needs to absorb more and more complete medicinal properties......

Persistence, must be persistent......

In this way, five minutes passed slowly at a turtle speed, and at this time, Duan Lie was almost fainting in pain.

However, when the medicinal properties were completely gone, all of a sudden, Duan Lie felt an extremely fanatical power emerge from the battle spirit, and the origin of these powers was the source of the fighting qi created by the potion of boiling blood that had just been absorbed......

The fighting energy surged to the limbs, to the organs, and to the spleen, turning into a warm current that could melt the ice and snow and protecting the cells of his whole body without exception, and an unprecedented sense of comfort was born.

"Ah...... It's so comfortable......" After a long five minutes, Duan Lie's whole body was soaked with sweat, but in the end, he still breathed a sigh of relief.

Slowly stretched his sore arm, the pain had not completely disappeared, but Duan Lie felt an extremely powerful force instilling his entire body and swimming.

The ninth-level battle spirit has improved a lot on this basis.

Duan Lie's eyes shone brightly: "I have finally found a quick way, the combination of a strong heart and boiling blood is the most effective." Duan Lie patted his head and scolded nonchalantly: "It's so stupid, why didn't you think of it before, you wasted months of time in vain." ”

In the days that followed, Duan Lie began to go crazy, he almost abandoned all spare resources, and fixed the main direction of concoction of potions on the strong heart and boiling blood.

The release of a large amount of strong heart and boiling blood turned him into a drug maniac, and then he was immersed in the pleasure of constantly torturing himself.

On his table, there were at least fifty groups of strong hearts and boiling blood, if others were to see this scene, it would be more than Duan Lie who should go crazy.

......

The devastation and tossing day after day created the appearance of a madman, and in three months, Duan Lie broke through from a ninth-level battle spirit to a tenth-level limit in one fell swoop.

Then, he continued to drink the strong heart and boiling blood, and finally positioned his strength at the peak of the tenth level.

Ten full months passed, Duan Lie finally touched the threshold of the war madness, and at this time, the clothes on his upper body were gone, and his strong body glowed with full blood red, like a blood-filled dummy, thick, strong, and full of strength......

Although he suffered a lot of pain and suffering in the process, his mood was as optimistic as a sunny day in September.

Because he knows that he is not far from "flying".

As a very ordinary person, what a beautiful moment to be able to fly......
