Lines of handwriting soon emerged in front of Su Yuan's eyes, making his eyes shine brightly.

It is worthy of being a copper treasure chest!

This gives too many good things, right?

He immediately checked.

Copper blocks and ordinary runes are ignored directly.

[Water attribute runes: one of the advanced force runes of the dark world, which can add the attribute of ‘water’ to your room.]

【A very precious thing, two need to be used together. Once used, all the water sources around the room will become sweet and delicious, full of spiritual energy.】

…

[Elementary evolutionary medicine: the most primitive evolutionary medicine medicine method.]

[Don't underestimate it, it has a high probability that some dark creatures can evolve from "normal" to "rare", and even have a certain probability of evolving into "rare".]

…

[Design drawing of Ziguang Armor: a rare equipment that can effectively resist attacks for you.]

【Wear it, your defense will increase tenfold.】

…

Su Yuan saw from above and down.

Good guy, no matter which of these three things is very useful to him.

Especially the following two.

However, the materials needed for the two below are too rare.

【Elementary evolutionary medicine: Xuanyuan grass (0/1), purple diamond flower (0/1), red flower grass (0/2)】

【Purple Light Armor: Purple Light Stone (0/2), Copper Block (0/6), Silver Block (0/4), Metal Rune (0/2)】

…

There are only red flowers and plants on him now, copper blocks and a metal rune.

As for the others, nothing is there.

There are some things he hasn't even heard of.

But it doesn't matter if you haven't heard of it. Just find someone to trade after you go back. Maybe others have it.

Finally, Su Yuan temporarily withdrew his attention and looked at the huge floating leech on the lake.

What if this thing was taken as a guard?

He immediately ordered a group of guards around him to drag the leech up.

Several guards began to go into the water, swam towards the leech, and grabbed its huge body and pulled towards the shore.

This Black Water King slept very deeply.

Even if it drags it like this, it will not react at all and will be at mercy.

Su Yuan directly took out a contract scroll and covered it with it.

Saw!

Flashes of light flashed out, and soon the extremely huge water emperor disappeared and entered the scroll.

Su Yuan smiled and immediately opened the guard bar.

…

Guard name: Black Water King

Number: 1.

Level: Advanced (can be upgraded with the room).

Quality: Rare.

Introduction: The powerful and terrifying Water King is best not to provoke it.

…

"The level is actually high-end, and the quality is also [rare]. The starting point is higher than other guards as soon as it is started. Even the evil spirit in red is not its opponent?"

Su Yuan was stunned.

This thing is so scary?

But such a terrifying thing was knocked down by three small herbs?

It made him feel somewhat unbelievable.

In the end, Su Yuan released this thing again.

After being successfully contracted, the Black Shui Emperor finally woke up from his dormancy. It seemed that all the medicine in his body had been eliminated. It poked out its huge head and looked at Su Yuan, then looked at the other guards around him, and immediately kowtowed slowly towards Su Yuan.

"It's quite sensible, good."

Su Yuan laughed directly.

But this guy is too big to keep in the yard.

brush!

As soon as his thoughts arose, the Black Water King began to grow smaller quickly, from a radius of more than ten meters to the size of a slap in a blink of an eye.

This made Su Yuan look at him again with admiration.

Can you freely change the size?

If you have this thing as a room guard, the safety of its room may be increased by more than ten times at once?

He looked at the Black Shui Emperor with satisfaction, and then looked at the other guards beside him.

Now there are six guards, and it seems like he has become a summoner.

And conquering a Black Water King is equivalent to having all the leeches in the entire lake!

Now he can proudly announce that the entire lake belongs to him!

Su Yuan immediately took out the materials, clicked on the manufacturing column, and created a huge water truck and placed it next to the canal.

The water truck has the function of wind runes inside, so it can rotate without any external force.

Waves of water flowed faster towards the canal.

Su Yuan took a group of guards around the lake and walked towards the room after he made sure there was nothing else.

The Black Water Emperor followed the water flow from beginning to end.

Soon, Su Yuan had already arrived in the yard again.

Seeing everything on track, he became more and more satisfied.

"By the way, the room can be upgraded again, and the two water-attribute runes are just enough to be used."

The light flashed in his eyes.

Immediately, I stopped wasting time and directly took out six ordinary runes to upgrade the room from one star to one and a half stars, and then used two water-attribute runes in the room.

brush!

The whole room began to change significantly again.

I saw that the originally 50 square meters room suddenly became larger and expanded directly to about 100 square meters.

And the yard of the room is actually expanding.

The original wooden walls became taller and thicker.

The darkness in the yard also dissipated a lot again, looking clearer.

Su Yuan showed surprise and looked at the yard and walls.

Can these things be upgraded?

He quickly opened the panel.
