When the same herb is put into the bath, the hot water, which was originally clear, immediately turns black.

Stir the medicinal herbs in the hot water, wait for a while, Xu Rong took off all the clothes on his body, and then entered the bathtub.

The heat of the hot water quickly passed through his skin and into his body.

The water is about 70 degrees Celsius, and when you first enter the water, it feels very hot.

Fortunately, Xu Rong's physique has been greatly improved, and he is also resistant to temperature changes.

After surviving the first few minutes, as Xu Rong's skin turned red, he began to stand up in the tub.

The qi and blood in the body continue to flow along a specific route, and the blood rushes to absorb the medicinal power from the outside into the body, and then carry this medicinal power to all parts of the body and penetrate deep into the bone marrow.

Under the stimulation of this powerful medicinal power, the bone marrow, which is already like hoarfrost, constantly produces fresh blood.

The blood was as heavy as mercury slurry.

Xu Rong only felt that his whole body was hot at this time, and the blood in his body was about to boil.

Beads of sweat soon appeared on his originally red skin, followed by pitch-black mucus.

A foul smell gradually filled the room.

After a long time, all the medicinal power in the hot water was absorbed, and Xu Rong was already wrapped in something black at this time.

And at this time, the room is simply stinking and disgusting.

"Why does it stink so much!"

Xu Rong smelled this smell, and the whole person was not good.

"This exchange of blood also has the effect of washing the muscles and removing the marrow?"

After these days of consolidation, Xu Rong has completely digested the improvement brought by the soul power provided by the soul fragment last time.

Therefore, after nothing happened in the afternoon, Xu Rong bought all the medicinal materials according to the prescription for blood exchange, and it was a full ten, saving time to run again.

Because of the pursuit of the best effect, and Xu Rong is not short of money now, this pair of medicinal materials for blood exchange cost nearly eighty taels, and ten pairs of medicinal materials are eight hundred taels.

That's enough money to buy two houses in the inner city.

It can only be said that practicing martial arts is really burning money.

However, the effect is really good, and the first time I used it, I had such an obvious effect.

Xu Rong roughly cleaned the black things on his body, and then poured out the dirty water and replaced it with clean water.

After that, I brushed it several times before I finally confirmed that there was no smell on my body.

After opening the doors and windows for ventilation, Xu Rong came to the courtyard and felt much more comfortable.

At the same time, he also felt that his strength had increased again, and at the same time, his qi and blood were more condensed, and his body was more coordinated.

Even the senses are much sharper.

"This is the first time, and after ten times, the complete blood exchange is successful, and the improvement will be even greater at that time."

The effect of the medicinal materials after that is definitely not as good as the first use, after all, it is resistant, but when it is superimposed ten times, it can also be regarded as reborn.

"Qi and blood condensation will also help to condense the blood furnace later, or in other words, if you want to successfully condense the blood furnace, you must be thorough in the exchange of blood, otherwise even if you succeed by luck, the quality of the blood furnace is estimated to be average."

Xu Rong still lacks knowledge in this area.

The reason is very simple, the strongest person he came into contact with was only the Blood Furnace Realm, but Tie Ying and Gao Han didn't guide him.

The others belong to the former head catcher Zhang Yu's decades of knife training experience that are the most useful.

But Zhang Yu is just in the realm of refining the marrow, and Xu Rong has already surpassed him.

At this point, Xu Rong can only slowly grope his way forward.

After practicing with a stone lock in the courtyard for a while, Xu Rong finally adapted to the growing power.

"Before the exchange of blood, I had the strength of thousands of catties, and with the increase in qi and blood, it was close to two thousand catties."

"Now for the first time to exchange blood, the growth force is about 200 catties, but it is already a very exaggerated number."

"If I punch now, it is estimated that it will be more than 2,000 catties."

Xu Rong clenched his fists, his face filled with excitement.

Two hundred catties may not seem like much, but it is actually a very big increase.

Even if you practice for a year, you may not be able to increase your strength so much.

This is still in a period of rapid progress, and some of those who have encountered bottlenecks may not be able to increase their strength by ten catties even in a year.

"Sure enough, the human body also has limits, so the ancestors created the exchange of blood and let the human body begin to evolve."

Xu Rong's body shape at this time is not much different from before, but his strength has really increased, and his weight is also a lot larger.

In this way, it means that the density of Xu Rong's body has also increased. It will also be more resistant to hits.

……

Early the next morning, after Xu Rong finished practicing, he came to the yamen.

Tie Ying and Gao Han have already left and returned to the Demon Division to resume their lives.

And the person who presided over the daily task this morning became Huo Mingjue.

As for Zhao Long, he has changed from a deputy catcher to an ordinary catcher today.

And because of what he had done before, everyone was isolating him, consciously or unconsciously.

Even the few guys who were around him before kept their distance from him at this time.

Zhao Long didn't seem to care about such a change, or rather, he had accepted it.

But even if he doesn't want to accept it, there's no way.

After Huo Mingjue finished assigning today's tasks, he let everyone disperse.

Xu Rong and Liu Zizai converged, and the two glanced at each other, and they both saw the joy in each other's eyes.

The reason is very simple, Zhao Long was assigned to their part and gave them a hand.

In the past, because of their identities, the two of them were not good to Zhao Long.

And now, Zhao Long is already an ordinary catcher, and they naturally don't have too many scruples.

Even if they didn't attack Zhao Long directly, they had other ways to rectify him.

The two did not wait for Zhao Long, they went directly first, and explained the relevant matters to the officials.

After Zhao Long came to the stronghold in Chengbei District, he was a little hesitant.

He knew very well that he had a grudge against Xu Rong and Liu Zizai, and after he came here, he would definitely be bullied.

But he had to come, because he still wanted to keep his position as a fast catcher.

If he doesn't come, Liu Zizai and Xu Rong will probably sue tomorrow.

With the relationship between Zhao Long and Huo Mingjue, Huo Mingjue wished that Zhao Long would get out of the way as soon as possible.

If Zhao Long dares not to come today, he will be swept out of the house tomorrow.

After waiting for a while, Zhao Long gritted his teeth and walked into the stronghold.

No one looked at Zhao Long, as if they hadn't seen this person appear here.

Zhao Long didn't know what the other party was doing, but he was also relieved.

And just like that, the first day passed.

Liu Zizai and Xu Rong didn't seem to have any intention of retaliating against him.

Seeing Zhao Long leaving alone, Liu Zizai laughed: "I don't know what this Zhao Long thinks in his heart now?" ”

Xu Rong smiled: "I guess I'm still rejoicing." ”
