Various abilities can effectively help eliminate other contestants in the deathmatch and obtain settlement rewards.

Lu Bai glanced at the ability pool and scratched the back of his head: "But what is this black thing?"

【Warhammer】【Primarch】【Super Seminary】【Great Crusade】【Angel】

Annan's soul merged with the Primarch's, and after the fall, he unified the planet with the Primarch's superhuman wisdom and strength.

He established a regime whose sole faith was the Emperor, and used the planet's resources to build crude but efficient war machines, always ready to join the Great Crusade.

The planet is shrouded in a militaristic, Emperor-worshipping atmosphere.

Until one day, the gorgeous Sky Blade series battleships appeared in the planet's orbit.

Angels discovered this unified civilization during their routine inspection, but their technological level was "abnormal"...

What does it mean that the Emperor didn’t come, but the angels did?

What does it mean that angels can fly?

Lin Feng traveled to a world of cultivating immortals. He was born in poverty and possessed the lowest level of [Five Elements Mixed Spiritual Roots]. At the beginning, he was chosen by the deacon of Changqing Sect to be an outer sect servant, responsible for guarding spiritual herbs and feeding spiritual horses.

A cultivator with mixed spiritual roots like him would find it difficult to cultivate to the middle stage of Qi Refining in his lifetime. He would waste a hundred years working like a slave for the sect and eventually die in disgrace.

Fortunately, Lin Feng awakened the [Lifespan Plundering System]. As long as he killed a creature with spiritual energy with his own hands, he could plunder its remaining lifespan!

Moreover, he can also consume his lifespan to improve his cultivation, advance his spiritual roots, change his physique, and deduce martial arts techniques!

So.

[Ding, detected that the host has cut the first-level "Green Grass", and gained lifespan: 1 year! ]

[Ding, the host has invested a hundred years of his lifespan to upgrade his own five element mixed spiritual roots to low-level wood attribute mixed spiritual roots!]

Time passes and the world changes.

Lin Feng picks flowers and weeds, slaughters spiritual animals, and achieves immortality!

Gradually, the secret rumor that there was an immortal staying in the Changqing Sect spread!

One day, an extremely powerful enemy appeared and attempted to wipe out the Changqing Sect. The current leader of the Changqing Sect knelt on the ground and asked the immortals in the sect to take action.

Then, an old servant in sackcloth appeared, smiled slightly, and slapped the powerful enemy to death.
