The Daily Life of the Immortal King - Chapter 2146: ,142, Infinite Defense (1/86)

In a modern world where cultivators need a place to cultivate or vent their boredom, there are private businesses that set up instance dungeons with the aid of technology and cultivation magic to enable cultivators to train and commoners to experience the life of cultivation. They are called dungeon suppliers.
Xie Jin's one and only dream was to be a dungeon supplier and when his only relative passed away, the relative's inheritance gave him a plot of land and surprisingly, a 'System' Module which the relative had previously used.
With the help of the system, Xie Jin decided to pursue his dream of becoming the number one dungeon supplier.

I, Zhou Mingrui, transmigrated to an alternate world and became an ordinary little skeleton.

I received a system at the start which made me more powerful whenever I killed an enemy.

I can draw the health, mana, and other stats from the dead.

Every 10 levels, I can also awaken a talent.

Level 10: The Book of the Dead.

All incantation time for Undead Spells is shortened by half, and their effects are increased twofold.

Level 20: Skeleton Armor.

Build weapons and armor that are suitable for the user using skeletons. Weapons can be upgraded when the user’s level increases, while the armor can be upgraded to increase its immunity against all negative effects.

Level 30: Soul Summoning From River Lethe.

The user can summon dark creatures. The maximum number of summons increase with the user’s level. The summoned creatures’ stats are increased significantly.

I, Yan Wuyue, leader of the human. I am crowned the [Goddess of Savior] by the people of this world.

I reincarnated 30 years before the apocalypse. I have to get stronger in order to change history and save humanity.

So, my initial summon monster is extremely important.

I thought I could sign a contract with a dragon, a phoenix, an angel, or some other creature from the ancient myths.

But when that ordinary, unassuming little skeleton fell from the sky…

I was plunged into despair.

Even the most ordinary sorcerer could summon a ton of these things with a wave of his hand!

Being able to see into people's past has no real appeal for the teenager this story is about, letting him use it only as amusement and to show off when he was drunk.Never watch into someone's past beyond a superficial level.Never try to find out more than you should.NEVER. EVER. LOOK. INTO. THE. FUTURE.But everything changed the moment he was forced to look into the future, was forced to investigate a murder, and was forced to make the acquaintance of the victim's twin brother('s fists).The more time passed, the more it appeared that the primary reason for this murder wasn't a local problem, but a global one.This single, marred corpse was the beginning of a threat that would shake the world.(MC looses a screw when he enters the prison)BL, first-person view; MC is shuo (perhaps even a reversible couple); love interest falls in love first; both MC and ML are straight, mutual bending, Enemies to Lovers
