Demon Slayer: I, a ghoul, save the regret!

Yamanako herself had not yet developed, so she could only endure the punch.

Muzan's mission was important. After controlling five teachers from Douma, Yamanako left the Gokuraku Cult.

Time was short and the mission was heavy. If you want to find someone with strength, you have to use some extraordinary means.

Yamanako sneaked into the government and found a lot of information. She also found the person she wanted from these information.

Two robbers sentenced to death slaughtered 53 passing villagers and stewed the children into broth. They were extremely vicious.

A doctor, who had excellent medical skills, was blinded in one eye because of medical disputes. The stimulated doctor killed the patient with the scissors he carried with him and is currently detained in the hospital for treatment.

There was also a 20-year-old man who had studied in the Suliu Dojo for five years, but because he could not control his emotions, he had a conflict with other dojos and accidentally killed three people and injured 16 people.

The Suliu Dojo expelled him and sent him to the government for detention, but he injured officers and soldiers during the escort and is currently on the run.

In addition, Yamanako also found four substitutes. She spent three days to capture them and took them to Upper Rank 6, Kyudai Rei.

Only Upper Ranks have the ability to turn humans into demons, so Muzan asked Yamanako to find someone and send him to Kyudai Rei.

Kyudai Rei is considered to be the one with a stable temper and easy to talk to among the Upper Ranks. The others... hard to describe.

Upper Rank 1, Kokushibo, has never been seen many times. He doesn't take anyone seriously. Yamanako is afraid of being disliked if she asks him for such a small matter.

Upper Rank 2, Go Nami, only listens to Muzan's orders. He is an out-and-out, quiet and rigid ninja.

Upper Rank 3, Douma, Yamanako doesn't like him.

Upper Rank 4, Hantengu, hides all day and can't be found.

Upper Rank 5, Yuhu, is ugly.

Upper Rank 6, Sanyueliang has a bad temper and communication problems. Only Kyudai Rei is relatively normal.

Seeing the people sent by Yamanako, Jiudai Li turned them all into demons neatly. One of the substitutes couldn't hold on and died.

Blood Demon Art·Blood Parasitism

Yamako separated seven drops of blood and put them in their bodies for monitoring and positioning.

"I'll give you one month. After one month, you will have the opportunity to participate in the blood battle of replacement and become the lower string."

"If you haven't beaten the lower string, you will only die."

"I will come to you when the time comes, don't let me down!"

This blood battle of replacement is not only related to the lower string, but also to his own promotion. As long as two of the demons he found can defeat the lower string, it means that he is capable enough.

The demon king will give him more blood, and then he can start preparing to launch a blood battle of replacement. At that time, he should have one more upper string!

The seven demons were sent away, and Yamanako didn't stay for long. Muzan didn't like demons to gather together.

Time passed quickly. One month later, in the Infinite City, the four lower-rank demons had already arrived, as well as the seven demons who challenged the lower-rank demons and some veteran demons.

Compared with a month ago, the aura was much stronger. It seemed that Yamanako had also spent some effort to cultivate it. Otherwise, if they were all wiped out, Yamanako and Muzan would not look good.

The round-robin battle was very disadvantageous for the lower-rank demons, but Muzan's orders were everything, and he could not show it even if he was dissatisfied.

Lei did not dare to be arrogant. He carried a samurai sword and had not been idle in these years. He learned a lot of swordsmanship from the gym. Although it was not as good as the breathing method, it was also a means of saving his life.

It was divided into four arenas. After five rounds, three lower-rank demons were replaced, and only Lei persisted.

Those demons came up one by one, and Lei had a little difficulty dealing with them, but Muzan called for a stop.

"Lei, keep the lower-rank five."

Looking at the dirty venue, Muzan frowned unhappily. A pipa sounded, and the Infinite City began to rotate, and soon a clean surface was replaced.

"From now on, the first lower string is Nightmare, the second lower string is Du Ming, the third lower string is Crazy Dog, the fourth lower string is Langya, and the sixth lower string is White Wind Cloud"

After hearing that the fourth lower string was replaced, Yamako felt worried, but she didn't dare to look at Muzan's face.

Obviously, there are two... who have become lower strings, why...

Du Ming is the doctor who lost one eye, Crazy Dog is the student kicked out of the Suliu Dojo, and the others are some old-fashioned ghosts who have taken over.

Feeling Yamako's panic, Muzan reached out and inserted the whip tube into her head, injecting more blood.

"Yamako, you did a good job, you will be the seventh upper string in the future."

"Your current task is to help me find the blue Higanbana, and if a lower string dies, help me fill it up immediately."

The words in the blue pupils began to change, and Yamako immediately knelt down to express her gratitude, "Don't worry, sir, I will never let you down."

The lower string also got more blood, and this performance was very tiring.It's good now. He is the only lower moon left. Muzan is very satisfied.

The bloody battle of replacement ended, and the Infinite City returned to peace again.
