At this time, Lu Kun could really feel the qi and blood in his body, and the mana at the peak in the middle stage of Foundation Establishment. It was like a dream.

More than 40 days ago, after he was healed, he tried to observe the new blood in the bone marrow.

It was only then that the bone marrow deep in the bones turned golden yellow. It was necessary to know that the bone marrow that was capable of hematopoietic before was red, while the bone marrow that did not make hematopoiesis was yellow.

But when Lu Kun broke through the bottleneck, he didn't know what happened in his body. Not only his red marrow that could make blood, but also the yellow marrow that had no hematopoietic function before had turned golden.

Golden marrow?

Why do they all change color and can make blood?

Lu Kun, who couldn't figure out the reason, could only continue to run the mana in the bone marrow cavity, and through its urging, he tried to make the golden bone marrow accelerate hematopoiesis and complete the blood exchange process.

During this exchange of blood, the mana in the blood began to slowly increase.

Lu Kun found that to generate one blood mana in his body, he needs to consume nine mana in the bone marrow cavity, which means that the conversion ratio of this blood mana is nine to one.

That is to say, the golden marrow needs to absorb nine parts of mana, and these energies can produce a fresh blood with mana.

The conversion rate is too low.

Lu Kun can only keep this doubt in his heart. Fortunately, the spiritual energy in the Demon Island is countless times stronger than the outside world. Even if the conversion ratio is a bit large, there is no problem.

After the five days passed, that is, after the first round of blood was replaced, Lu Kun began to feel that something was wrong, because in these five days, he had gained a little more mana.

You must know that when he first entered the foundation-building stage, the bones could only hold a small amount of mana due to the lack of tempering. According to his speculation, the middle-stage foundation-building stage of physical training should also have such restrictions. Mana is limited.

But in the past five days, Lu Kun had not encountered the limit of mana capacity, so he wanted to find this limit, but he kept practicing, and the blood in his body changed round after round.

The mana in the blood, until the end of the ninth round, the mana in the blood can feel the limit.

At this time, Lu Kun also discovered all his physical mana, reaching the peak in the middle stage of foundation building, which immediately surprised him.

Surprisingly, this strange phenomenon between bone marrow and blood mana.

The happy thing is that he reached the peak of the middle stage of foundation building so quickly, saving a lot of time, so that he has more time to study the method of body repairing and knotting.

Lu Kun couldn't believe it, and immediately aroused the power of qi and blood in his whole body.

Sure enough, the huge amount of qi and blood made him feel shocked. Even the fifth-level silver-spotted leopard of Uncle Xu didn't seem to have as much as him.

…

After bowing his head and thinking for a long time, Lu Kun realized that the black man in front of him was crawling on the ground, and his eyes were even more awe-inspiring.

His expression changed and he said, "Da Hei, do you feel the increase in the power of my bloodline?"

Da Hei immediately whimpered and cried, and he was so excited that he shed tears.

"Squeak! Squeak!" Xiao Jin quickly translated for Da Hei.

Lu Kun showed a thoughtful look: "As expected, because I entered the middle stage of foundation building, that is, the realm of blood refining in physical cultivation, the blood of the golden giant ape is stronger."

"This time, Da Hei, felt a little breath of its ancestors."

"It seems that the golden giant ape is really an ancient monster with immeasurable strength, and the race of the mountain black ape, Dahei, is the bloodline of this golden giant ape."

"Woohoo!" Da Hei cried out emotionally again.

"Squeak!"

Lu Kun nodded and said: "Okay, when I get out of the Demon Island, I will definitely visit your mountain black ape clan when I have time. I do have something to ask the elders in your clan."

At this moment, Xiao Jin suddenly remembered something, and danced to Lu Kun, feeling quite emotional.

Hearing this, Lu Kun's face changed: "What are you talking about, when my mana rushed into the bone marrow cavity, Xifeng's demonic energy was attracted by me and entered my body?"

"Squeak! Squeak!"

The little monkey nodded and gestured with his hands.

"You said that it took me a whole day and a night to attract demon energy?"

When Lu Kun heard what Xiao Jin said, he fell into deep thought.

"Isn't the time when the demonic energy that Xiao Jin said was attracted to me when I heard the roar of the golden giant ape?"

"Xiao Jin also said that these demonic qi entered my bone marrow cavity and disappeared. Could it be that I suddenly reached the peak of the middle stage of foundation establishment. Is it caused by the blood of the golden giant ape?"

Thinking of this, Lu Kun couldn't help recalling that many years ago, when he was cultivating the Vajra Art, he was trapped in the magic circle by the old ghost Murong.

"At that time, because of the bloodline, I quickly completed the cultivation of this realm. Now I use the mana to refine the bone marrow, improve the blood from the root, and also enter the culmination stage of this realm in a short time."

"If you look at it this way, it can only be explained by the bloodline of the golden giant ape. After all, it is the bloodline of the demon ape. It is not surprising to absorb the demonic energy. As for the demonic energy entering the bone marrow and disappearing, it should be acting on my bone marrow."

"The bone marrow turned golden, which is probably caused by demonic energy."

"Since it's the reason for the bloodline of the golden giant ape, then it's the same as the breakthrough in the Diamond Art, there's no future trouble."

"As for the many problems in the middle stage of foundation building and the realm of physical cultivation and blood, I will study it carefully when Qingtian and the others have reached this realm."

"Xiaojin is a monster, and it's definitely not the same as a physique when it reaches the third-level monster."

After thinking for a while, Lu Kun attributed his strange promotion to the peak of the middle stage of Foundation Establishment to the bloodline of the golden giant ape.

As for normal body repair, whether the bone marrow will change color, the conversion ratio of mana in the bone marrow cavity to blood mana, and the periodicity of exchange blood.

He intends to wait for Zhao Qingtian's disciples to be promoted, and carefully observe and study. His situation is that he skipped the cultivation in the middle stage of foundation building, and he lost a little experience in the process of physical cultivation, which will have an impact on the later exercises he created. .

Lu Kun stopped thinking~lightnovelpub.net~ looked at the little monkey and said: "Xiaojin, that demonic energy is attracted to me, it is very likely the reason for my bloodline, you don't need to worry about this part, you can take care of the rest of the process of hitting the bottleneck. Remember it."

Xiao Jin nodded vigorously.

Then Lu Kun took a robe from the storage bag and put it on again, looked at the solid ground that was still pressed down under his feet, squeezed the fist of his right hand, and slammed it down.

"Boom!"

I saw the stone reinforced by the three intermediate and high-level fossil spell talismans shattered, and even the cave temporarily dug by Lu Kun trembled.

Lu Kun felt it carefully, and murmured: "The physical strength has increased a lot, and it looks like 70,000 to 5,000 pounds."

"Similar to what I predicted before, this realm will not increase the strength too much, but it will increase the endurance of the physical body and the stamina of high-intensity attacks."

"And under my perception, the blood vessels of the whole body have been strengthened a lot after these forty-five days of blood accumulation, but I don't know what the effect is."
