[Exquisite crossbow arrows (crossbow machine): Breath of filth 7/3, iron block 35/3, copper block 30/1, silver block 10/1]

[Exquisite crossbow arrows (arrows): filthy breath 7/1, iron block 35/1]

Bai Mu clicks [Make].

Successfully manufactured items will be automatically stored in the inventory, and Bai Mu will take out the fine crossbow arrows.

Rather than saying this is a crossbow, it is better to say that this is a low-end version of a pistol. There is a movable buckle on the side of the crossbow. Pull it back and an arrow box will appear. Put an arrow about twenty centimeters long into it and pull the trigger.

You can shoot a powerful arrow.

The crossbow arrows can be fired continuously and can shoot all the arrows in the arrow box at once.

Bai Mu looked at the space in the arrow box and found that it could hold about 10 arrows.

Bai Mu clicked [Create] again and made 2 more arrows, making up three arrows.

If there is more, it will be gone and the material will not be enough.

Bai Mu put the arrows into the arrow box.

Pick up the crossbow arrow and press the trigger directly against the wall of your home.

Whoosh!

Three bursts!

All the arrows pierced the stone wall, leaving three small holes in the wall.

"The power of this shot is too strong!"

The shot hit the stone wall and left only three holes.

Bai Mu was very satisfied with the power of the sophisticated crossbows. It seemed that the sophisticated weapons were indeed extraordinary.

There are only three levels of weapons that Bai Mu knows now: those with no level, which are usually damaged weapons; the ordinary level, which are normal weapons that can be made with ordinary materials; the third level is the sophisticated level, which requires the breath of filth to make.

.

The gap between ordinary grade and fine grade is already very big. I don’t know what other grades follow the fine grade and what materials are needed to make them.

Bai Mu is looking forward to getting higher-level weapon blueprints.

Bai Mu walked to the wall, recovered the arrow, and then spent 1 stone to repair the wall.

After putting away the sophisticated crossbow arrows, Bai Mu turned his attention to his home, and the next step was to upgrade his home.

Install a wooden door first.

[Wooden door: wood 37/10, iron block 29/1]

Click [Create], then click the [Deployment] option in the home.

Install the wooden door to the door frame.

The light flashed by.

I finally have a door to my home!

Bai Mu stepped forward and patted him.

It's good, very thick, and made of 10 wood, it's still very material.

Then Bai Mu clicked on the toilet drawing, spent stones, soil and traded sand. After successfully creating it, he clicked [Deploy] in his home and arranged it in a corner of his home.

In an instant, a small cubicle appeared in the home.

Bai Mu made toilet paper again, spending 1 wood and getting 10 toilet paper.

The bathroom needed glass, so Bai Mu traded 50g of roasted spider meat for 2 glasses on the exchange, and then arranged the bathroom in the toilet.

Now our home finally doesn’t look like a “house with bare walls”.

Bai Mu also pointed out [low-level water maker: copper block 29/4, iron block 28/3, wood 27/1, low-level mechanical core 3/1]

Click [Manufacture]

Bai Mu only made one water maker, and he still needed to keep two low-level mechanical cores to repair the mechanical puppet.

Another water generator appeared in the home.

Bai Mu added 10 pieces of wood to the new water maker, which is enough to run for 5 hours and is expected to produce 2500ml of water.

Now the two water generators, running 24 hours a day, can get 12 liters of water!

This time I don’t have to worry about getting into the water.

If the exchange's other two low-level mechanical cores can successfully trade, Bai Mu plans to make two more water generators.

Water, Bai Mu can never have too much.

Bai Mu looked at the wall of his home again.

[Wall (stone wall): Iron block 25/10, upgrade (iron wall)]

Bai Mu clicks to upgrade.

The entire home has changed from a stone wall to an iron wall. The iron blocks are integrated into the entire wall. It still has the texture of the stone wall, but a layer of iron blocks is attached to the surface.

From a look and feel perspective, it is quite solid.

When Bai Mu clicked on the farmland and prepared to arrange it into his home, he ran into trouble.

[Farmland cannot be arranged in the current area, please expand your home and try again.]

Yes, it cannot be arranged.

But there is no place to look up how to expand your home.

Bai Mu looked at his panel again and finally remembered that there was a LV.1 logo in the upper right corner of the panel.

Click in and you will see the conditions for upgrading.

[System upgrade LV.2: Kill 3/5 cave monsters in total (regardless of level)]

[Newly opened functions in LV.2: Drawing Research Institute, increased home upgrade limit, home expansion function]

"Drawing Institute?"

After Bai Mu clicked in, there were relevant instructions from the Drawing Research Institute.

[Drawing Research Institute (Level 1): Using materials, you can choose the manufacturing path and obtain relevant ordinary-level drawings]

"So this means that we can use materials to reverse the drawings?"

"It's interesting."

This also saves a lot of trouble in finding blueprints, but only ordinary-level blueprints can be deduced.

If you want higher-level drawings, you need to continuously upgrade the level of the Drawing Institute. Currently, there are no upgrade conditions for the Drawing Institute. According to Bai Mu's guess, the upgrade of the Drawing Institute is also linked to the system level.

Leave it alone for now.

You can upgrade the system level first before talking about it. Among the system upgrade conditions, I have only killed sand krait, mutant hyena and six-eyed poisonous spider so far. I only need to kill two cave monsters to meet the upgrade conditions.

Bai Mu decided to find a soft persimmon to squeeze first.

Click on the map.

The cave at the back is an abandoned mechanical puppet warehouse. I came from here and there are no monsters.

The cave above is a botanical garden, but due to lack of water, all the plants have died.

The cave below is a wetland, and there are three unleveled mutant alligators in it.

The air in the cave ahead contains highly toxic substances, and there are a group of poisonous bats inside.

There is mineral water and ham sausage in the cave on the left. The quantity is not much, 550ml of water and 1 ham sausage.

The cave on the right is empty.

After Bai Mu read the information about the surrounding caves, he had many choices. He could choose to kill the alligator, or he could first transition to the caves on the left and right, and then check the information on other caves.

Bai Mu thought for a while and checked the alligator information first.

[Mutated alligator: It just wants to bask in the sun and will not actively attack any creature unless it is hungry.]

View【Strategy】

[Mutated alligators will not avoid any damage. They firmly believe that their thick armor can withstand any damage, so you only need weapons with sufficient penetrating power, such as powerful penetrating arrows in ordinary level or sophisticated level weapons.

You can kill them without any damage.】

Now the choice is easy.

These three mutated alligators are simply the best prey for his sophisticated crossbows.

It cannot hide, and arrows can penetrate defenses.

The most important thing is, kill without injury!

Bai Mu decided to go to the cave below, took out his shovel, and started digging downward.

【Soil 1】

【Soil 1】

...

After digging for almost half an hour, Bai Mu finally dug through the cave, this time with a transparent air wall.

Bai Mu saw three mutant alligators.

Lying on the ground motionless.
Chapter completed!
