Naruto: The Outsider's Resolve - Chapter 5.22 (16)

The brash Li Chengfeng makes a living through trickery with his clueless but loyal servant, Xiaobao. One day, the love of his life is murdered, making him a suspect, and he meets a demon who suspects he is the reincarnation of a traitorous immortal.

A reputation as ‘The Most Feared Gunslinger In the West’, and the Law hot on his heels, Henry Morgan had lived a full life. So when it all ended with a gunshot to the back of his head, he was quite ready. He embraced death… He embraced his end.Except it wasn’t the end…Some mysterious [Powerful Forces that be] wrenched him out of the world he knew and deposited him into the body of a version of himself in a Parallel world. A world where something as ‘impossible’ as Magic apparently exists.These [Powerful Forces that be] went a step further by granting Henry a System and issuing him strange prompts and Quests that send him down a road of Adventure and bloodshed all so he can etch his name in history and show this world and its many ‘wonders’ just how deadly a Gunslinger can be…

10 billion people in the world traveled through the apocalypse to survive, but the protagonist directly turned into a zombie after crossing…

And with the passage of time, the body is gradually decaying.

For zombies: Rotten clean = dead.

So, Jiang Si’s time is running out…

In order to survive, he opened the novice gift bag.

Got the trash skill: ?Xingchang?br>“?Xing Changhe? After eating alien creatures, you can get additional experience points. If the ingredients are fresh enough, there is a chance to get this biological skill.”

…

Um.

Really useless.

Alien creatures are full of poison, and the taste… is extremely unpalatable!

Eat alien creatures to gain skills?

That is courting death!

Such rubbish skills, after all…

Etc., etc? !

right? !

I’m a zombie. Since I can eat people, isn’t it the same to eat xenogeneic creatures? !

With a move in his heart, Jiang thought to a possibility.

Then, the journey to eat the world began:

“Ding, you ate the Poison Horned Rabbit and gained 400 experience points, and your skills are fast.”

“Ding, you ate the Lion of Ice and Fire, gained 5800 experience points, and the skill Flame Body.”

“Ding, you ate the Wetland Poison Dragon and gained 180,000 experience points and skill dragon scale skin.”

“Ding, you ate the true ancestor of vampires…”
