After traveling through time, opening a bottle, and accidentally releasing the demon inside, what should I do?

"Since the fourth hundredth year since I was trapped in the bottle, I swore that whoever saved me would be killed!" "Ouch! So fierce!"

In order to survive the demon, Lu Ye had no choice but to...

"Go in!"

Past, present, future, and destiny. These form the foundation of the world and represent the power of the present. The past is eternal, representing unchanging power. The present is the era, representing the strongest power. The future is potential, representing infinitely powerful yet infinitely weak power. Chosen by the past, one becomes the master of the unchanging. Chosen by the present, one becomes the king of the era. Chosen by the future, one becomes the emperor of the end and the emperor of hope. Chosen by destiny, one becomes the emperor of fate! The chosen youth ultimately embarks on the path planned by destiny. Not wanting to be bound by fate, he continues forward. If humanity cannot achieve this, then he will become a stronger being, until he becomes an ultimate existence that even gods cannot look directly at. The world is finite, but dimensions are infinite. Continuous battles lead to becoming the ultimate being. Becoming the master of destiny! The female lead is Yae Sakura (?ω*?). Worldline: Akame ga Kill! → Fourth Holy Grail War → Godslayer → Dragon Clan → Problem Child [First two volumes are for beginners, poor quality]

Kato Dan, a Konoha Jonin who died on the battlefield, was not allowed to enter the Pure Land; instead, he was bound to the Death God System.

Awaken your Zanpakuto, gather the dead, build the Soul Society, and reshape the order of the dead.

"What? The 'corpse demon' in the Corpse Demon Seal is actually a spirit-eating monster?"

"It's alright, I have countless prospective Grim Reapers backing me up."

He ignored the system's warnings about not interfering with the living world.

"If I become the Grim Reaper and then ignore everything, wouldn't I have wasted my life?"

The creation of the Gotei 13, Nawaki, Sakumo Hatake, Sasori's parents, and the longing of countless dead souls for their loved ones.

"The final resting place of the deceased is defined by me!!"

Death God vs. Ninja, Ninjutsu vs. Kido, Chakra vs. Spiritual Power

Behind the scenes of the ninja world, countless 'people' are watching.

Then let me, the Grim Reaper, reshape the ninja world!

From today onwards, this world will be renamed the World of Death.

Those who peer into the world of death will be peered into by death itself!

Crab Invitation, while picking up a package, was hit by a tractor and transported to the world of Crayon Shin-chan. Surprisingly, they were transported at the same time. Crayon Shin-chan Daocheng: "Everyone knows this is a funny, everyday show. It's safe! So, brothers, please help me." Naruto Daocheng: "...Studying medicine can't save the ninja world after all." Armor Daocheng: "You caught him, why are you asking me to get out of the way? Don't you think that's ridiculous? Come on, let's see whose sword is faster!" "Still watching? I'm here to take you down!" One Person Daocheng: "I'm just an employee. I'm paid to do the job. Who dares to mess with me? I'll take them down!" Warhammer Daocheng: "It's just a life-or-death struggle. Let me go." Fox Demon Daocheng: "I have a lot of momentum, but my strength is a little low." Seer Daocheng: "Damn, I'm not a second-rate guy!" Kuiba Daocheng: "Overthrow the hegemony of the gods! The world belongs to me!" Star Travel Daocheng: "Believe in miracles..."

Good news: I've traveled through time, to the world of Fairy Tail. Even better news: The magic can summon plants, and not just any plants, but the ones from the Plants vs. Zombies mini-game. Bad news: I haven't seen Fairy Tail, so I don't know the plot. Even worse news: The summoned plants aren't the ones Kern is familiar with. ...Kern, having traveled through time, gazed upon the summoned [Worker Sunflower], [HR Ice Shooter], [Surplus Value Sun Mushroom], and all sorts of other bizarre plants, lost in thought.

Yun Shen transmigrated, but he was different from other transmigrators.

He didn't transmigrate into a human; instead, he transmigrated into a suit of armor.

To be precise, it's the Asura Armor, the Asura Summoning Device.

As long as he finds a suitable summoner and absorbs their heart power, Yun Shen can infinitely increase his strength.

At this moment, there was a suitable person in front of Yun Shen who desperately craved power.

His name was: Beria...

(PS: The stories will not be limited to the Ultraman world; they will also explore the worlds of Ultraman Armor and Ultraman Mask, as well as many other worlds.)

Want to know what it's like for the Blood Emperor to not go bald? Then come and see for yourself. A work by the Rebellious King.

The Blood Emperor stomped the flying squirrel on the ground, laughing heartily, tears welling in his eyes. Finally... finally, he wouldn't be losing hair anymore, he wasn't balding.

Wu Yuan, who accidentally acquires a quest system and a chat group system, begins wreaking havoc across the universe. In Ben 10, he teams up with Ben to fight alien monsters. In Minecraft, he dances with Steve. In Jackie Chan's Adventures, he engages in close combat with the Holy Lord...

At his sixteenth birthday party, Lux joined the chat group. He had no friends since childhood and longed for a sincere and passionate friendship. He thought he could fulfill his wish, but unknowingly, he was getting further and further away from his wish...

The most evil spirit: Alara... Hehe, don't be fickle, Lux. A fickle person will swallow a thousand needles.

The seventeen-year-old beautiful girl: You stole my heart, but you never admit it. You are such a scumbag, Lux.
