The Yanxia Federation welcomed the 12th millennium civilization ceremony of its wizarding civilization. Magical energy particles from beyond the boundary brought warm magical energy currents, nourishing the civilization's mother body. The cries of the darlings of fate made the era increasingly noisy and bustling. An invitation from the advanced wizarding civilization's [Ether Dream Network] was about to open the [Ether Dream Realm], a place of both danger and treasure. Deep within the potion chamber, after concocting and drinking a bottle of [Civilization Potion], Li Yan opened his eyes again. Beneath the clamor and bustle of the wizarding civilization, the hidden disasters and crises began to surface. The [Black Emperor], who had borrowed from an unspeakable evil god, paid the price of the entire civilization's demise for the [Undying Potion], and was now secretly coveting it. The [Parasitics], whose goal was to "parasitize civilization," had found new prey. ...

Fang Yi obtained a grass block, allowing him to freely travel between Earth and Minecraft without any cost. (This is not the vanilla Minecraft version; mods will be added.)

Shortly after gaining his abilities, he discovered that the Honkai had descended. (This is a story about using Minecraft items to fight against the Honkai.)

"Soul Emperor? Is he strong? If I strike him with one palm, he might die!"

"Emperor Yan? What Emperor Yan? Oh, it's 'Brother Yan'..."

"Brother Yan, don't misunderstand, they are all my wings!"

This book is also known as: "Unable to Cultivate Battle Qi, I Had No Choice But to Advance to Immortal Martial Arts Through National Martial Arts", "The Miraculous Healer, Doctor Xiao", "The Valkyrie's Training Manual", and "Within Thirty Years, I Will Become the Most Powerful Woman on the Entire Continent".

Years later, Xiao Yan sighed helplessly, "All these years, I feel like I've been living in her shadow..."

Having transmigrated to a martial arts world, Li Changsheng only wanted to stay put and write his diary.

Looking at the diary system in front of him, Li Changsheng knew that someone must have obtained a copy of the diary.

Thinking that as long as he didn't expose himself, no one would find him, Li Changsheng wrote his diary as he pleased.

Today they complain about this, tomorrow they complain about that, they've complained about every single beauty in the world of martial arts.

But who knew, the system, in its cruelty, actually brought people along...

Qin Yu was reborn back to the summer when he was eighteen, and accidentally sent out a mass text message confessing his love.

The good news is that he doesn't have many contacts on his phone.

The bad news is that his father, mother, aunt, cousin, and homeroom teacher are all inside.

The good news is that he doesn't have many women his age in his contacts.

The bad news is that he scared his childhood sweetheart to tears and also attracted the attention of a yandere junior.

After the college entrance examination, Lin Xiao went online to find summer jobs in order to earn pocket money.

But when he accidentally clicked on an advertisement, he was dumbfounded. He found himself on an alien battlefield, becoming an interstellar mercenary.

Before me stretched an endless swarm of alien insects, along with space armor, spaceships, and robotic warriors.

Lin Xiao reluctantly joined the battle.

He soon discovered that although it was dangerous, the rewards were equally huge; by continuously completing missions, he could also earn a huge amount of money.

Two months later, on the interstellar battlefield.

Interstellar Commander: "Lin Xiao, in view of your numerous merits in the war,

The Legion has decided to promote you to Commander of the First Battle Group. Congratulations!

Lin Xiao: "I'm sorry, sir, I can't accept this."

The commander asked in confusion, "Why?"

"Because I have to go to school..."

"With just a small price to pay, even a wish like destroying the Burning Legion can be fulfilled!" "So, what is the price?" In short, it's the story of Illidan Stormrage becoming a magical girl and fighting in different worlds to achieve his wish of destroying the Burning Legion.
