Previously, at twelve o'clock, all the resentment and hatred that had been piled up on Xiao Heng were absorbed by the system and then transformed into blood qi, plus Xiao Heng planned to kill a large number of people every day during this time, and the speed of Xiao Heng's cultivation during this period of time also improved rapidly, and he had already entered the late stage of the body refining realm three days ago.

I'm afraid that even Wu Yuan can't imagine this speed.

Sitting cross-legged on the bed, he slowly moved in his body according to the exercises of "Killing", and the speed of the exercises was extremely fast at the beginning, but after running a circle, he began to slow down.

The operation of the first circle is mainly used to absorb the blood qi in the body and then refine it, after one circle, these transformed blood qi quickly and gradually enter Xiao Heng's body, strengthening and refining all parts of Xiao Heng's body.

What's more, now Xiao Heng's body has been tempered to a certain extent, and the speed of refining is even more like a snail than at the beginning, and this speed is naturally slowing down.

With the continuous refining of these blood qi, Xiao Heng's body couldn't help but tremble slightly, his brows were also tightly wrinkled together, and his handsome face was faintly distorted at this moment, as if he was enduring some great pain.

Three days ago, after Xiao Heng broke through, he entered the late stage of the body refining realm after refining his skin, muscles, muscles, bones and internal organs, and he had already reached the last step of body refining, the realm of refining the marrow.

More than half a month ago, Xiao Heng was still in the bone refining stage, and after half a month, he had already completed the bone refining and organ refining and entered the marrow refining marrow, and the speed in this was not unfast.

If Xiao Heng meets Fang Yu again in the university martial arts club, he has a similar strength. Xiao Heng will not be easily repelled like the last time, but can kill it quickly, this is the difference in the starting point.

Refining the essence should be said to be the easiest realm to break through in the body refining realm, but it is also the most difficult realm to break through.

Bone marrow belongs to everyone's hematopoiesis, and the amount of blood in a person's body is constant, once there is a lack of blood in the body, then the bone marrow will start hematopoiesis as the beginning, until the blood volume in the body returns to this constant value before stopping.

In other words. If you want to determine how quickly a person recovers after an injury, then the strength of the bone marrow is a big factor in determining the speed of recovery.

When the blood qi has quenched the bones, there is not much bone marrow in the bones, so the blood qi and time consumed should not be too long, but the difficulty is that the pain in it is too intense, and ordinary people simply can't bear this kind of long-term pain, and finally have slackened and give up cultivation.

At this time, Xiao Heng's body seemed to have thousands of steel knives constantly scraping his bones, and it seemed that there were thousands of ants constantly climbing and biting in it. A sharp pain mixed with a sore, tingling sensation that came from the bones of the body. From within. Pulling the whole body, more painful.

Originally, Xiao Heng thought that the biggest pain was the pain in the medicinal bath, but when he entered the marrow refining realm and began to refine the marrow, he knew that the pain in it was worse than the previous few medicinal baths.

At this time, Xiao Heng's face was faintly distorted, and the sweat of the bean was constantly dripping down. Even the white sheets under the body were quickly wet, faintly transparent.

When refining the marrow, it is different from the rest of the body, the more you refine the bone marrow in the depths, the more these pains will increase, which is simply a constant test of the strength of Xiao Heng's willpower.

At the time of enduring the pain of the current refining of the marrow. Xiao Heng couldn't help but think of the medicinal bath in his heart, although the pain of the last medicinal bath was not as painful as this time. But don't forget that the last medicated bath was only the third time, and there are still seven chances to come, and presumably the pain of the last medicated bath will not be less painful than the pain of the marrow refining, and may even be more intense.

Thinking of this, Xiao Heng's heart couldn't help but feel bitter, but after thinking about it like this, he felt better when he experienced the pain at this moment.

The speed of refining was directly proportional to the pain Xiao Heng endured, the faster the quenching speed, the more intense the pain in Xiao Heng's body became, and this situation lasted for an hour before it stopped.

When the exercises stopped due to the exhaustion of blood and qi, Xiao Heng's body was directly paralyzed on the bed, regardless of the sheets on his body and underneath, they were all wet, and the whole person seemed to have collapsed.

Sensing the degree of refining in the bone marrow, Xiao Heng smiled bitterly, originally thought that with a large amount of blood qi, he could finish refining the bone marrow today, so as to break through the refining realm and enter the refining qi realm, but he didn't expect that the deepest bone marrow would be so difficult to quench, and it was only about half of it tonight.

"It seems that we can only wait until after twelve o'clock tomorrow night to refining, and then enter the Qi Refining Realm in one fell swoop." Feeling the degree of tempering of the bone marrow, Xiao Heng thought secretly in his heart.

Until now, Xiao Heng was extremely greedy for the kind of ghost fire that Wu Yuan showed when he met Wu Yuan for the second time, but that kind of thing can only consume blood and qi condensation in the Qi Condensation Realm, and now Xiao Heng is just about to enter the Qi Refining Realm, and he doesn't know which monkey year and Ma Yue he has to wait until he enters the Qi Condensing Realm, and he is extremely sang-feeling when he thinks about it.

If Xiao Heng's idea was known by Wu Yuan, Bao Bu would rush up and beat Xiao Heng again, from Xiao Heng's official start of cultivation to now, it has only been two months since he was full, and he will immediately enter the Qi Refining Realm, this speed is not satisfied, so how can Wu Yuan, who had been in the Body Refining Realm for a year, feel embarrassed.

The severe pain during the previous marrow refining had squeezed all the strength in Xiao Heng's body, and he could only collapse on the bed and think nonsense, and after waiting for about ten minutes, his body could barely move.

Then Xiao Heng dragged his body to the kitchen.

Xiao Heng's kitchen put aside some modern tools, and almost all other places were filled with the medicinal herbs he bought, and from the beginning to the present, Xiao Heng had never cooked a meal for himself, strictly speaking, it was no longer a kitchen, but a pharmacy.

The current body has experienced the previous tempering of the body, the body is sore everywhere, if you don't want to find a way to soothe tonight, when you get asleep, it is estimated that the whole body will be like falling apart.

After finishing everything, it was already three o'clock, and after a busy day of work today, coupled with the pain he endured when he quenched the marrow before, Xiao Heng fell asleep after changing a sheet.

The next day, Xiao Heng was woken up by the ringtone of the mobile phone placed next to G, and connected the phone with a little unhappiness, and the sound that came out made Xiao Heng's face change.
