After Nuwa reported the positions and schedules of all the robots to Li Yao, she realized that these guys had practically surrounded her. Since Dazhuang was still inside, she finished washing up and lay down on the bed with peace of mind.

In the middle of the night, Li Yao suddenly felt someone beside her. Without opening her eyes, she used her mental power to scan and found that it was Da Zhuang who had suddenly approached her, looking wary.

Li Yao opened her eyes and asked, "What's wrong with Dazhuang?"

Dazhuang replied, "Master, there's something unusual in the sky above us. There are dark shadows flying back and forth. Based on their trajectory analysis, they are conducting a purposeful probe, but they are moving very fast. We haven't been able to capture any images or analyze what they are yet."

After listening, Li Yao called the system: "[6834, have you detected what it is?]"

The system replied: [It's a peregrine falcon with speed abilities, hunting for food. But isn't this house supposed to be invisible? However, there are solar panels visible from the sky, which probably just piqued its curiosity. I'll wake you up if there's any danger, don't worry.]

Upon hearing this, Li Yao realized it was a peregrine falcon with a speed boost. Wow, the legendary fighting bird among birds! But since it was just a bird, Li Yao didn't pay much attention and went back to sleep peacefully.

She told Dazhuang to go back to the living room and play by himself, but Dazhuang insisted on standing guard for her, so she let him go.

The next morning, after Li Yao got up and washed up, she ate breakfast while watching videos that Nuwa, the special-grade robot, and the black-grade robot dog had taken during their reconnaissance in the forest.

Some trees in the forest have become unusually tall, and there are patches of dead trees and plants around them. Li Yao thinks that they have mutated and are competing for nutrients in the soil.

This forest contains many redwood trees with straight, thick trunks and leaves at the top. The tallest redwoods can grow up to 84 meters tall, and there are several here that, according to the special-grade robot, are all over 100 meters tall.

Perhaps because they were machines, they didn't encounter any unexpected situations when they entered the woods. However, when Li Yao watched at double speed, she suddenly noticed that there were several dark shadows flashing by last night.

She switched back to normal speed and realized that the shadowy figure looked somewhat like a human, but since these guys weren't firing, it meant there was no threat. Using 0.5x speed, Li Yao finally saw the full figure in one of the robots' cameras.

It was just a gorilla. Well, Li Yao was disappointed. She had thought she would encounter some strange species.

She asked Nuwa, "What's going on with this chimpanzee?"

Nuwa replied, "Master, it's a chimpanzee that has awakened a special ability—the ability of speed. There are several chimpanzees deep in this forest, but they haven't attacked us."

Li Yao nodded to indicate that she understood. It seems robots do have their advantages. Lacking human characteristics and a heartbeat, they are generally considered inanimate objects by animals and plants.

Li Yao had a wild idea: what if the robots stood in front of the zombies and pounced on them, only to have them all break with a single bite? The thought was hilarious, so she decided to give it a try today.

After eating and drinking to her heart's content, and having a cup of spiritual spring water, Li Yao returned to the [Spiritual Spring Space] and trained for two hours before going back to the Invisible House. As usual, she inquired about the zombie upgrade progress of the day from the system.

The system replied: [Host, over 2000 zombies have reached level 10 and have begun frantically devouring other zombies to level up.]

She has relatively few level 7, 8, and 9 crystal cores, so she decided to collect one less batch today.

Li Yao then arrived at the edge of the cliff, looked down at the zombies feeding around, and said to the system, "[6834, let's warm up today. Collect 100,000 crystal cores from each of the level 7, 8, and 9 zombies, use spatial cutting to shred them into dust, and then use designated target teleportation to retrieve the crystal cores.]"

The system happily acknowledged receipt, and after about 5 minutes, she gained 300,000 skill points, 100,000 level 7 crystal cores, 100,000 level 8 crystal cores, and 100,000 level 9 crystal cores.
