"Congratulations to the host for obtaining a strand of acquired Yin Qi. Reward: 10 points."

The system's voice then sounded.

Li Siyuan also showed a satisfied smile on his face.

One minute later.

Li Siyuan encountered two spider corpses.

Fight with full strength, rush forward and punch one by one, earning 12 points.

Ten minutes later.

Li Siyuan encountered a Yin corpse that looked like an earthworm.

In the end, this Yin corpse provided Li Siyuan with 8 points.

Half an hour later, Li Siyuan was besieged by three humanoid corpses. After a battle, he wiped out all the corpses and earned 30 points.

…

An hour later, a Yin corpse that looked like a tiger but not a tiger, and a leopard but not a leopard appeared in front of Li Siyuan. The combat power of this Yin corpse was quite considerable, even stronger than that of a human-shaped Yin corpse. Li Siyuan fought with it for more than ten moves, and at the cost of being grabbed by the Yin corpse on the chest, he blasted half of the Yin corpse's body with a punch.

Fortunately, Li Siyuan's physical defense was amazing, and after being grabbed by the Yin corpse, only a few white claw marks appeared on his chest...

The harvest was also gratifying, I earned a total of 15 points.

After resting for half an hour and recovering all his strength, Li Siyuan stood up and went deeper into the cave.

…

Two hours later...

Half a day later.

Li Siyuan has already earned 421 points.

What I gained in half a day was more than what I gained in the whole day yesterday.

There are three main reasons for the current situation.

First, Li Siyuan had made sufficient preparations and had enough sunstones to minimize the impact of darkness.

Second, he had an understanding of the Yin Cave.

Third, his combat power has been further improved.

The combination of these three points led to today's scene of quickly harvesting Yin corpses.
