Comic System in Naruto's World - Chapter 19

“Obtaining the topmost degree of talent in sword arts in the world requires giving up 72 years of lifespan, which leaves you with only five more years of your life. At the same time, you will never be able to feel love, kinship, and friendship, and you’ll end up leading a lonely life until your death, unable to procreate, or to have any descendants.

“From now onwards, everything related to happiness in the human world shall no longer be of your concern. Are you willing to accept this?”

“Hahahaha, I’m already alone bereft of all support, my hopes dashed to pieces, shouldering only absolutely irreconcilable grudge and hatred, why would I disagree? Why would I not want it? I couldn’t ask for anything better!!”

His sword sweeps across the Divine Continent for seven days and nights, moving 90,000 miles through the starry skies, unhindered.

He slays saints and buddhas in Heaven, slaughters demons and devils in Hell, sweeping away all the grievances in his heart!

After the nth time of failing a marriage meeting, Xiang Han got himself a job: good treatment, high salary, free world traveling with food provided, house provided and even a ‘lover provided’?!

At first, he thought, apart from having to travel into the body of a scum cannon fodder, a scheming fake white lotus, everything else was okay. It was only later he realized that saving the target was also a problem. His imagination was neverending, even eating a cup of ramen was seen as a way to rouse his ( target’s) interest!

Xiang Han: This target is a no-go.

Certain Target: Very good, you’ve already managed to rouse my interest.

Xiang Han: Go outside and make a left turn to the optometrist, go get your eyes healed! Additionally, this “lover provided” isn’t necessary.

A Certain Target: This is certainly necessary!
