Yue Zhenshan traveled through the Republic of China and found that this world had Qigong cultivation, poisonous Gu corpse refining, alchemical magic, and strange scholars who talked about mysterious science. He started with a blacksmith shop and suppressed the world with iron and blood...

No female lead + time travel + adventure + anime

DanMachi World: Boss, you must be a Berserker!

"Huh? You have a problem. I already told you I'm an assassin!" After saying that, he picked up his twin swords and charged into the monster horde with his Musou attack activated.

Fairy Tail world: "Kimitsu, give me some healing!" Natsu, who had been beaten to the point of vomiting blood, shouted to the person behind him.

"Heal you? Impossible. You charged out the moment I applied the buff. How am I supposed to heal you? I'll have to rely on fatherly love."

Food Captures the World: Who says alchemists can't cook! I just added a little medicine to your dishes!

The protagonist is reborn as Rufus, one of the five strongest warriors of Saberbite, a bard singing under the red moon.

He's the one who uses memory-shaping magic, the one who got knocked out by Gray in the Grand Magic Games arc.

(The protagonist's main magic skills: Time Annihilation Magic and Memory Shaping Magic.)

(PS: A completely new storyline; the protagonist will become the second Magic King.)

When the end of the world comes, the world is in disrepair.

Zhou Lin was reborn three days before the natural disaster and gained the ability of "symbiosis".

After much thought, he got on a flight to the island.

Two days later, the world was shocked:

The largest and most advanced nuclear-powered aircraft carrier in the beautiful country disappeared out of thin air after completing the supply in the port of the island country!

Beautiful countries, island countries and summer countries, Mao countries so the first level of readiness.

However, only 24 hours later, the island nation's Mount Shifu and the beautiful country's stone and yellow volcano erupted at the same time, and the last days of natural disasters came...

Traveling to a world of cultivation where demons are rampant and strange things are everywhere, Lu Yuan only wants to find a paradise with abundant and pure spiritual energy, various spiritual medicines, and raise spiritual pets, so that he can live peacefully until the end of time.

Wait...something seems wrong...

The cave is actually me?!

Fortunately, when a cultivator mysteriously enters the secret realm, Lu Yuan can extract their spirit seeds, treasures, bloodlines, magical powers, etc.

Looking at the various rewards in front of him, Lu Yuan chose to change his posture.

We welcome monks from all over the world and accept all the wonders in the world.

"Fellow Daoist, please enter the cave."

As long as the sea of blood never dries up, Su You remains indestructible! The gathering sea of blood fosters an immortal body! The condensed blood spirit nurtures countless incarnations! Step by step, Su You ascends to the pinnacle of the universe, treading upon the flesh and blood of alien races! PS: The timeline is slightly later than Luo Feng's, and he doesn't follow the original protagonist's path.

Reborn in the world of Devouring the Stars, still a baby!

Ren Ze is confused... But don't panic, just hold on to the thighs first!

After eight years of waiting, the golden finger is finally in the account!

Not enough talent, build a foundation in the low-level martial arts world.

The law is hard to understand, wander around the world of immortal heroes.

Passerby: Why haven't I seen your telekinetic weapon?

Babata: Impossible!

Absolutely impossible!

How can you avoid the master's secret inheritance!

Bolan: I admit that your talent is indeed strong, but I will not admit defeat!

Original Ancestor: This kid is interesting.

He can perform these messy things independently of the original universe system.

Although it is a bit weak at present, it is also a direction to try.
