Tanjiro Kamado: Yes! Mr. Kamogen is a very powerful person!

Agatsuma Zenitsu: Kamigōnen, is work the only thing on your mind?

Inosuke Hashibira: Damn it! I can't surpass you again? Moonlit Night!

No heroine, a growing protagonist, invincible in the later stages, weak system, many battle chapters, high-energy throughout..........

[Invincible] + [Old Six] + [Gou Daoliu] + [Funny] + [Relaxed]

Invincible from the start, Gu Changge travels through a fantasy world, is bound to a sign-in system, and signs in every day to receive cultivation rewards and various peerless treasures.

While others were still struggling to break through, he had already stood at the top of the avenue and became a hidden emperor whose strength was unknown to himself.

I wanted to just lie down and enjoy my retirement at Zizhu Peak, but the system suddenly issued a task - to recruit a disciple.

Gu Changge had no choice but to pick up a few apprentices:

The eldest disciple was born with the body of a god of war. He was given a copy of "Strategies of the God of War" by him, and as a result, he fought all over the nine heavens and ten earths and became an unparalleled god of war who swept across the universe.

The second disciple, with the Chaos Sword Body, can break all laws with one sword. His sword is unrivaled in ancient and modern times. He points his sword to the sky: "My master said, the sword is as long as the person lives, but when the sword dies... my master will give me another one."

The third disciple, the reborn empress, ascended the throne again, her beauty and grace overwhelmed all living beings.

And his own sect, Qingxuan Sect, unknowingly became the number one sect on the continent.

Looking at this group of extremely talented disciples, Gu Changsheng pinched the "Hongmeng Purple Qi" he had just signed in and fell into deep thought:

— What happened to the promised retirement care? How did you become the strongest master?!

(Charizard Invincibility + Red, Green and Blue Two-in-One Template + Pure Idealism)

"You want my tutorial on becoming the strongest in the world? Don't you deserve it? You want my tutorial? And you want to become the strongest in the world? I know that the strongest in the world can only be me!"

Standing before you is the strongest, true rookie in the Pokémon world! The Star of Kanto, Chairman of the Alliance, a figure of dragon and phoenix, the face of the sun and the moon, the leader of the Orange League, the eight-time champion, the master of all attributes, the collector of legendary beasts, the nightmare of rookie trainers, the reaper of random trainers, the master of Pokémons, and the invincible warrior, Xia Yu!

[Crossing + System + Invincibility + Summoning + Sect + Decisive Killing + All Heavens and Worlds]

Lin Li traveled to a new world and was inexplicably bound to the sect system, establishing Kunlun and rewarding peak cultivation.

[Ding, congratulations to the host for successfully binding to the system and receiving the novice gift package! ]

[Ding, congratulations to the host for obtaining a Enlightenment Tea Tree! ]

[Ding, congratulations to the host for accepting a personal disciple and receiving a luxurious disciple gift package! ]

Linli lived a relaxed life in the sect, taking in disciples, fishing, eating hot pot and being at ease. Gradually, the disciples all became peerless masters, and the sect became the strongest sect.

[Invincible + Peak Strength + Decisive Killing + No Hiding of Cultivation + Overwhelming All]

He was once an ordinary person on Earth, but after an accident, he traveled to the world of immortal cultivation where the strong prey on the weak.

A hundred thousand years of bloody battles, from a mere mortal to the top of the myriad realms, stepping on the gods and demons in the heavens, and slaying the immortal immortal king with a sword!

His name once made three thousand planes tremble!

Now, breaking the void, returning to Earth.

Bullying me? In a flick of my hand, the whole family is reduced to ashes!

Those who betrayed me? Their souls will be extracted and refined, and they will never be reincarnated!

Respect me? I will grant you an eternal life!

The Immortal Emperor has returned, and it’s time to change the rules in this world!

In the True Immortal Continent, warriors are respected.

Qin Ye accidentally traveled to another world and became the head of a small sect that was about to decline. He obtained the most powerful system, and began by accepting his first disciple, building the strongest sect in the universe step by step.

[No realm drop + invincible from the start + decisive killing + no hiding of identity] He cultivated for three hundred years, becoming the renowned Lingtian God of War in the Immortal Realm. Upon his return to Earth, he further advanced, surpassing the Immortal Emperor realm. This time, I, Ye Lingtian, will avenge my grudges and repay my kindness. I am invincible below the Immortal Emperor, and even above him!

[The Great Emperor + Invincible + Cool Writing + Sweeping Sweep + Decisive Killing] One hundred thousand years ago, foreign invaders came, leaving thousands of miles of land devastated and all the people in the world suffering!

In order to protect the people of the world, Emperor Lu Xuan went into the abyss alone, using himself as a medium to suppress the entrance to the foreign land!

But he didn't expect that one hundred thousand years later, he would suddenly receive a call from his descendants' bloodline!

"Grandfather, are you still alive?"

"If you don't return soon, the Lu family will...die out!"

…

On this day, the Heaven Burial Sword, which had been sealed for a hundred thousand years, was reborn. The sky wept blood and myriad swords wailed in grief!

"I am just old, not dead!"

"A bunch of ungrateful people, how can they be worthy of my protection!"

Deep in the abyss, Lu Xuan was furious, and his cold voice spread throughout the heavens!

"I have guarded the Abyss for a hundred thousand years for the sake of the heavens. How dare you ants insult my descendants and sever my legacy!"

"In that case, let's drag the heavens down with us to be buried together!"

On this day, the seal of Tianyuan was lifted, the foreign land came again, and the heavens fell!

I talk to you about feelings, but you want my kidneys.

Ye Feng bravely tried to save his wife, but his body was thrown into the wilderness.

After being murdered, he accidentally traveled to a world of immortal cultivation where strength is respected.

After three thousand years of hard training, Ye Feng became the Ye Xian Emperor, respected by thousands of people.

But he could never forget the woman on Earth who killed him.

In a great battle, Ye Feng was besieged by many top warriors. When he was about to die, Ye Feng unexpectedly returned to Earth in a reborn form and was reborn as a freshman with the same name.

Only three years have passed on Earth.

A dog licker?

Are you about to jump off the building after being rejected by your goddess?

No, how could I, the great Emperor Ye, be a bootlicker?

I still have the power of an Immortal Emperor. In this life, this world is destined to be trampled under my feet...

ps: It is an urban cultivation theme, the male protagonist is decisive in killing, there is only one female protagonist, and the protagonist is not the only cultivator in the city. However, even a cultivator is like an ant in front of the protagonist.

Su Baiyi traveled through time, into chaos, bound to the daily sign-in system. And so… a billion years passed. Until one day, he was summoned by a young girl as a guardian spirit. The girl looked at Su Baiyi, a guardian spirit space larger than the world… and it was a mess. Inherited cultivation techniques? Just a few pieces of toilet paper were god-level cultivation techniques! Foundation-building elixir? Even the scraps were god-level elixirs! Wait… the senior's pet… a divine dragon?! A true phoenix?! And that monkey?…
