The epidemic came in full force, and it was impossible to suppress it so easily. The country would be willing to spend money, sparing no effort in treating the disease.

After all, the entire country could be wiped out if the disease flourished. Every emperor would be afraid.

However, the epidemic disease would not be purged so easily. There were always people unafraid of death.

“Wei Na, don’t check what’s happening outside for the time being. Pay attention to the points.”

“Okay, Master!” Wei Na replied happily. It was happy as long as the points increased.

“I think…” An Jiuyue remembered something suddenly.

Her father had left behind a small box, which seemed to contain something important. She had this box.

However, it was a box without a key. She did not know if he had forgotten to give her the key or if the box did not have one.

The Host had once searched the treehouse and could not find a key. She later stopped searching for the key because she was busy making ends meet.

Perhaps the Host did not search thoroughly, she thought.

An Jiuyue got up from the bed, ready to search again. This time, she had to search carefully.

How could a box not have a key? With her knowledge from her previous life, opening it would not be difficult.

However, this was no ordinary box. She suspected she might destroy the contents within if she forced it open. Nothing would be left.

The Host might not have realized this, but she knew—there was more to Old Tu than meets the eye.

He might not have left behind a small item. It could be very useful. Hence, opening the box was necessary.

Wei Na, who had been paying attention to the points, could not resist asking, “Master, what are you looking for? Are there rats in the treehouse?”

It wondered what she was doing. She had thoroughly searched the rooms, including the kitchen and storeroom, but found nothing.

She had even considered crawling under the stove to search for it…

But who would hide something under the stove? They had to start a fire every day. Even a piece of iron would melt slowly under the heat.

“Rats won’t crawl under the stove either. They’ll become roasted rats easily.”

An Jiuyue was extremely shocked.

I’m not searching for rats! I’m searching for a key!

She had previously thought the Host did not search carefully.

However, she had searched everywhere carefully without sparing a single corner. She was just short of tearing down the bed made of wooden planks and searching it.

“Wei Na, where can a key be hidden?” she asked quietly.

“It’s either inside or outside the treehouse” Wei Na replied casually. In any case, it was not the one searching the entire treehouse. Besides, it did think the key could be outside the treehouse.

Wei Na’s reminder stunned An Jiuyue.

That’s right. Who said that the key must be inside the treehouse? Maybe it’s outside? But where can it be?

Suddenly, she recalled her father talking about a large tree hole above this tree. A five-colored squirrel was living in it. She had even fed it before.

However, the five-colored squirrel was bitten to death by a snake.
