After Su Yuan tried back and forth several times, he became more and more shocked. In the end, he decided to go back to the room first, wait until the room was upgraded and the guards were upgraded before returning to build a water truck.

The rice needs to be eaten step by step, and then talk about it first.

He came to the black fruit tree, waved his spear, and began to dig the soil.

With the help of the evil spirit in red, the fruit tree was soon dug out of the dark red ground by him.

Su Yuan lit a pile of torches here again, and after taking the fruit tree as a mark, he carried the fruit tree and walked towards the way he came.

[You have deviated from the room three hundred meters and are on the verge of danger. Walking to the left is your way of life.]

Su Yuan immediately followed the prompt and walked over quickly.

At the same time, the banshee owl above his head was also constantly rotating within an radius of eighty meters above his head.

More than ten minutes later, the Banshee Owl above his head finally discovered the location of his room.

Su Yuan immediately took a step forward and ran quickly towards the room.

After entering the room, he immediately closed the door, first put the black spirit fruit tree in the room, then took out the runes and started the room upgrade.

【Do you choose to upgrade the room?】

A line of game words emerged.

"yes."

Su Yuan stopped.

brush!

The three runes in his hand suddenly turned into a black light, overflowing from his palm, spreading rapidly like hazy mist, covering the entire room.

Then the hazy mist was quickly absorbed by the walls of the room.

The structure, walls and floor area of ​​the room have changed dramatically in the blink of an eye.

The room, which was originally only 10 square meters, has now expanded several times at once. The walls in the room are no longer the same as those of the previous painted walls, but have become thick and heavy rock walls.

Even on the left side of the room, a small living room appeared, and there was a small stove in the living room.

The style of the whole room suddenly began to change.

Su Yuan looked at all this with a look of surprise.

The properties panel then opened again.

…

...

"Even my own strength has changed. I went from the middle stage of the dark apprentice to the late stage, and the Dead Wood Art also reached the entrance hall from the first glance?"

After the room is upgraded, can the host become stronger?

"By the way, there are guards."

He immediately opened the guard bar.

brush!

…

Su Yuan saw from above and down.

Sure enough, it wasn't what he expected.

The evil spirit in red and the numb ghost bee were all promoted to intermediate level.

More importantly, the upgraded red-clothed evil spirit and the paralyzed ghost bee actually mastered an additional skill!

Su Yuan couldn't help laughing, and immediately called the evil spirit in red and the paralyzed ghost bee.

The appearance of the evil spirit in red has not changed much, and it is still the same as before, but the appearance of the paralyzed ghost bee has changed drastically.

Originally they were only as big as fingernails, but now they have become the size of a quail egg, dark red all over, the teeth in the mouth have become sharper, and even the wings have become four.

"Yes, I should be considered an adult now, right? I don't know if there are any mothers. If there are, I will breed them earlier, so that I can give birth to more ghost bees for me."

Su Yuan smiled.

Now, no matter the safety of the room or the strength of oneself, it is incomparable.

He suddenly walked towards the position of the meter again.

Total power: 300kwh

Power used: 0kwh

Note: When the power is exhausted, your room will no longer be safe. Please upgrade the room as soon as possible to get more power.

…

Looking at the power used above, Su Yuan's eyes flashed and he understood again.

"After the room is upgraded, will the [power used] be counted from 0 again?"

That's right, that's what it should be.

That's the fair!

Now he has 300 kilowatt-hours of electricity, which is enough to last for a month, right?

Su Yuan was in a relaxed mood and finally looked at the black spirit fruit tree. He picked the fruits on it and stuffed them into his mouth. After enduring the sourness, he carried the fruit tree and walked out the door.

Unexpectedly, after the room was upgraded to one star, the darkness outside the room actually subsided.

Within two meters outside his room, the light could clearly illuminate the surroundings.

Su Yuan didn't dare to choose a location that was too far away. He started digging a pit one meter on the left side of the room, and soon dug a sand pit half a meter deep. He directly untied his belt and urinated.
