Chapter 22 Upgrade your home, dig into the sandworm burrow

A lot of wood and iron ore have been obtained, and [-] kilograms of "concrete" are needed to upgrade the home.

According to Zhou Yu's earth experience, concrete is made by mixing "cement, water, sand, and stones", but unfortunately, although he knows the formula, as long as there is no synthetic formula, it cannot be fused.

You can't just dig a big hole and mix concrete by yourself, right?
"Why don't you see if there is any sale in the trading area?"

Zhou Yu entered the trading area and searched for "concrete".

no message.

I searched for "concrete formula" again, but there was still no news.

"It's weird, it shouldn't be~"

According to his speculation, even if the building materials needed to upgrade low-level homes are scarce, it is impossible to have no news.

He changed his mind and continued to search for "concrete". (common abbreviation for concrete)
Got it!

Dai Mengde#18923: [Concrete synthesis map, please exchange for a shovel! 】

"Need a shovel? Is this guy's shovel broken?"

After some private chats, Zhou Yu found out that this guy was unlucky. He accidentally dropped his shovel into the magma while digging the burrow. He had no digging tools and was trapped in the magma burrow. Now it is like a hot pot The ants on the ground are in a dilemma.

"Does Boss Zhou Yu have a shovel? Help me, or you can lend me the shovel first, and I will return it to you when I leave this cave!"

"No, I'll exchange it for you directly."

Zhou Yu happened to have a spare shovel, which was left by Andre.

"Great, thank you, Mr. Zhou, and Dade."

An extra shovel was exchanged for Dai Meng's synthetic map of concrete, which also saved his life by the way.

After the transaction is completed, the synthetic map will be stored in the warehouse.

[You have obtained: Concrete Synthesis Map]

[Do you want to learn immediately? 】

"Yes."

Open the fusion page, 20 kg of concrete, that is, concrete, requires 3 kg of water, 3 kg of cement, 5 kg of sand, and 9 kg of stones to be synthesized. In addition to water, other materials can be found in the trading area.

It took Zhou Yu a while to collect all the materials.

Just click "Fusion".

[The fusion is successful. 】

[Obtain: Concrete 20kg]

Click to upgrade the home.

[To upgrade your home to level 2, you need: stone x30, iron ore x30, wood x10, concrete x20kg]

[Do you want to upgrade immediately? 】

"Yes!"

【Upgrading, please wait...】

Zhou Yu was actually a little puzzled. For such a large project to upgrade his home, not many building materials are needed. The concrete only needs 20kg. If it is on the earth, it may not be enough.

After a while, the homeland was upgraded successfully.

The area has not increased, and the wooden house has become a stone house.

Clicking on the information of the home system, he can clearly see the current level, area, defense power, etc. of his home.

[Homestead Name: Stone House of Zhou Yu#86523]

[Area: 10+20 square meters]

[Defense Power: 70]

[Attack Power: 0]

[Additional equipment: 0]

【Level: L2】

The eyes of insight swept over, and the white characters jumped.

[Ordinary stone houses already have strong defenses, which can resist most of the primary cave creatures. The haven for adventurers to live in the early stage, the stone house is in hand, and the night is worry-free. 】

"Great, now I can sleep peacefully at night."

"The defense of the level 2 stone house has reached 70, so how can the next level of home be strengthened? And what do we need?"

Zhou Yu clicked the "+" sign in the upper right corner.

[You can upgrade your home to: a solid stone house]

[Building materials required for upgrade: stone x200, iron ore x120, wood x50, concrete x100kg]

Good guy!The cost of building materials has doubled!

If all these materials are gathered, I am afraid that a lot of water and food will be consumed, not to mention that the synthesis of concrete requires water.

Let's put it aside for now.

Although his water resources are abundant, they also need to be carefully calculated and used.

The home of level2 is enough.

Keep digging!
Wait for more resources to be dug before upgrading.

No.16 crypts are waiting for him——

[The crypt on the left is empty, and there are no usable materials. 】

The crypt on the left is the crypt where Andre came, and he must have collected all the things in it.

But no matter what Andre got from it, it had already fallen into his own hands in the end.

[Digging to the right, you will find a nest of poisonous snakes waiting to be fed. Their mothers have gone out for food and have not returned. If you want to attack this group of poisonous snakes, now is the best time. 】

[There are strange bats entrenched in the cave ahead, which may contain viruses, be careful! 】

[Continue to dig down, you will be thrown to death. 】

……

This time it seems that there is no good luck.

Venomous snakes, bats...

The snake burrows are full of small snakes, there is no danger, but there is no benefit.Not to mention the bat cave, can bat meat be eaten?I'm afraid it won't work.In case of any virus infection, there is no specific medicine in this cave world.

Zhou Yu looked back.

He entered the No.15 cave from above, so this time he had an extra chance to choose.

[The burrow at the back has a piece of sand, you can find protein-rich sandworms in the sand, the taste is not bad, and there is a mysterious scroll buried in the sand. 】

Sandworm?Mysterious scroll?

Could it be a magic scroll?
Zhou Yu began to think strangely.

No matter what it is, compared to poisonous insects, poisonous snakes and bats, the burrow at the back is the best choice,

dig!
Zhou Yu was full of energy, and Black Skin Wang Wang assisted.

Halfway through the digging, the soil began to loosen and gradually turn into sand.

When the last shovel is thoroughly dug out and the No. 16 burrow is entered, it will be a world of sand and soil.

Not the sand of the beach, but a combination of sand and soil.

There are a few bare plants growing sporadically, which looks more like a sandy wasteland.

"Oh, this crypt is so big."

This cave is about [-] square meters and about ten meters high.

"Where is the mysterious scroll?"

[There is nothing here except sand and soil. 】

[There are three sandworms hidden here. 】

[There is nothing here except sand and soil. 】

……

Zhou Yu's insightful eyes are like detectors, constantly telling him information about the underground.

[This is the nest of sandworms. If you dig less than half a meter down, you will harvest dozens of protein-rich sandworms. 】

dig!
Sandworms are meat too!
As soon as the shovel went down, a soft sandworm was dug out.

Slippery, like a bigger earthworm.

[Sandworms, eat sand to maintain life, with a simple body structure. When eating, you need to remove the sand grains in the abdomen. All insects can be eaten. It is rich in a lot of protein, and it is a favorite food of goblins. 】

"This sandworm looks too disgusting, it's soft, like intestines."

Zhou Yu suppressed his nausea, arrested it with his hands, and put it in the warehouse of the Internet of Things.

Keep shoveling.

The sandworm nest was dug.

Zhou Yu's intensive phobia is about to commit.

At the critical moment, he still had to rely on Black Skin, one claw at a time, to quickly throw out the sandworms, and Zhou Yu would collect them one by one.

"I don't know if you sell sandworms in the trading area, will anyone like it?"

Zhou Yu suddenly came up with a wonderful idea.
