Toaru Majutsu no Index - Volume 11, Prologue: The trip of Northern Italy. Un_Viaggio_in_Italia.

“National Immortal Cultivation World” is an immortal cultivation game that once exploded on Blue Star.

But in the past ten years, a large number of players have retreated and abandoned the pit, and the game has been shut down.

Qin Mu is the only one left to sign in every day to get experience, do quests and dungeons, and plunder resources…

For ten years, Qin Mu has occupied the first place in all the rankings, and his level has also reached the first place in the entire server.

“What a great game, it’s a pity it’s closed.”

When Qin Mu was depressed, he found that the game world suddenly became reality!

There are swordsmen flying with their swords, and their sword qi has broken thousands of miles; there are magic cultivators who violate the law and disobey discipline, and separate one side; there are immortals who set up sects and create their own fire; Qin Mu sees himself, the immortal emperor is complete…

But he found that the most troublesome thing was that all the Dao Companions he got married in the game were all realized.

Not only that, the dungeon quests he cleared in the game, the bosses he fought, and the female NPCs he stalked all came to life. The most terrible thing is that the system also exposed his identity as an Immortal Emperor!
