The universe begins with Demon Slayer: Kimetsu no Yaiba

[Mission: Completely clear out all the ghosts on Tengxi Mountain]

[Reward for completing the mission: Obtain the breath of wood (mastery); the ghost devourer level is upgraded to D level. D level ghost devourers can devour blood ghosts]

[Punishment for mission failure: The host’s lifespan is reduced by 20 years (the current host’s lifespan is still 81 years)]

Just after Bai Yu officially stepped into the depths of Tengxi Mountain, the super-dimensional travel system suddenly issued a mission.

After reading the mission details released by the system, Bai Yu became speechless. Is the system going to kill him this time? Can't we keep a low profile? Why must we kill them all!

And what does the remaining 81 years of life mean? Is your life so short? This is too inconsistent with my identity as a dimension traveler!

Bai Yu, muttering in his heart, felt helpless. Especially after knowing his exact lifespan, although as a person, living 100 years is considered a long life, but if the mission fails, 20 years will be reduced. This makes Bai Yu particularly uncomfortable. Is his life so worthless? If you say your life span will be shortened, your life span will be shortened!

However, in this way, his original plan was disrupted.

Without this mission, according to the selection requirements, all he had to do was lead Tanjiro to live leisurely on Fujirai Mountain for seven days, and then go down the mountain.

Because Bai Yu felt that the number of ghosts imprisoned in Tengxi Mountain should not be too large, no more than two hundred at most. In addition, since Tengxi Mountain is so big, the chance of hitting a ghost is not that high.

And {ghosts} only come out at night, so there are 12 hours a day that are safe.

After this calculation, Bai Yu felt that the survival rate for himself and Tanjiro must be 100%.

But after the system released this task, the situation completely changed. Bai Yu could no longer pass the selection by stalling for time like before.

After all, Bai Yu doesn't want to shorten his life by twenty years. Even if he lives to eighty, it is enough. The remaining twenty years don't matter. However, no matter how you say it, it is your own life. If you can say no, just don’t want it!

In this case, Bai Yu must go all over the mountain to find ghosts to kill, and finally kill all the ghosts in Tengxi Mountain.

This is a big project!

Bai Yu was also a little confused about the rewards for the mission. This wood breath does not seem to be a breath among the five major breathing schools, and it does not seem to be a derivative of other breaths. It feels like a breath independent of these breaths.

But what is the use of this wood breath? Will it improve my own strength?

"Senior Bai Yu, what's wrong with you?" Tanjiro shouted looking at Bai Yu who was suddenly stunned.

Tanjiro's call brought Bai Yu out of his thoughts, and then Bai Yu shook his head and said: "Tanjiro, we have to separate after entering the mountain."

Hearing this, Tanjiro was a little confused and asked, "Why are we separated? Didn't the master tell us not to separate as much as possible?"

"Because I have something to deal with. If you follow me in this situation, it will only be more dangerous." Bai Yu explained lightly.

"Tanjiro, you have to believe in your own strength. Even if you don't follow me, you still have the strength to survive. I will carve water marks on the tree trunks wherever I have been. As long as you see this kind of water on the tree trunks, Tattoo marks mean that this place is safe. Don't follow me, because it will be very dangerous."

Seemingly uneasy about Tanjiro, Bai Yu encouraged Tanjiro again, and then gave the final explanation.
