Wang Ziquan worked on the workload of thousands of squares for most of the day before he finished the safe house.

When he finished placing the last block, he looked at the giant metal creature floating inside the building under his feet, and a sense of accomplishment suddenly arose.

When he teleports to the space left in the center of the safe house, he brings an unparalleled sense of security at the same time.

The interior space is not too large, only five meters high, ten meters long and wide, totaling one hundred square meters. Perhaps in the past, this size was enough for ordinary people to work hard at the foot of the city for several lifetimes, but for now, where housing prices are not necessary, the interior space is not large, and even seems a bit cramped. However, if it is just used as a place for sleeping, it would be more than enough.

Wang plans to stay in his base No. 1 when he is going to bed, and when it is time to go to bed, he will teleport to this site until he finds a way to build a safer base.

In this way, the night when he lost his sense of the outside world due to sleep was firmly closed in this giant metal creation. I think even the birdman and the undead guys would feel helpless if they really had a safe house of five meters thick in each direction.

The most critical thing is the unknown existence from the underground world. I think even if they step on the ground, they will not be able to easily enter the metal barrier hanging in the air for a while. Of course, no one dares to say that such a thing is 100% sure. After all, all monsters in this world have excellent magical abilities. If there is any special type of metal, then gg.

So when Wang Zi thought of this, he simply added a whole layer of wood to the outermost layer as a disguise.

"Oh, it's a pity that there is no magic barrier or something, so I can only do this."

He sighed, and he could only do the best he could do so now, that's all.

After simply laying the interior decoration with some furniture, I teleported it out to see that it was still early outside. It was just past 2 pm, which was the brightest time of the day - although it was covered by a blizzard, I couldn't see the sun.

After thinking about it, he teleported back to the front-end positioning point again. It was still a long time before it was completely dark, and it was enough to explore another building.

Next, Wang Zi took the bank building as the center and began to explore the past one by one along the buildings marked on the map on the river bank. This time, in addition to quickly obtaining the items, he also focused on finding the same hole traces in the underground space.

As expected, the result was shocking - there were more or less similar traces under all the buildings in this area. Even in the space where the traces were supposed to be food warehouses, the ground was densely filled with the same holes, and the people who saw it... their scalp was numb.

What is underground in this area?

Wang Zi couldn't help but feel a little lucky that he had never encountered similar situations in the underground spaces where he had walked before, so he was no longer lucky.

But it is not necessarily the case. After having the Rabbit Motorcycle, I had a car underground, but it was skipped by lightning. The Rabbit has its own attack power, and it can basically break the blocks and other things in an instant. It will fly directly into the inventory and it has no time to see it. Who knows what is in the passage passing by?

Thinking of this, Wang Zi's face changed again. It seemed... he still had no care in the underground tunnel at the beginning? The nearest tunnel is not far from his underground base. No, he must be blocked!

Thinking of this, he had to teleport back to the base again and then arrive at the ground position.

The entrance that entered the underground was closed casually. At this moment, I still have to remember it if I find it again. But there is no way, who made me lazy...

It took me half an hour to finally find the entrance to the underground passage in my memory. After opening it, it was pitch black inside, and what followed was the whimpering sound accompanied by the sound of the wind, like crying and complaining, and a bit cunning.

The method of Wang Zi's choice to block the tunnel was very simple. He first blocked the direction close to his base with iron blocks, and then opened a new passage to the riverside. Although the current temperature has completely frozen the river water, as long as spring comes, the river water after breaking the ice will quickly overflow this underground passage, saving time and effort. The only problem is that there is no way to do it in winter.

In the same way, Wang Zi finally let go of all the underground caves that he dug out at the beginning near the base. No matter what, the things he could think of had been done, and the rest could only be discussed when he encountered them.

After getting these things done and looking at the sky, he simply teleported them to the whiteboard, preparing to solve today's supper while talking about this matter with him.

"Underground? I don't know very well... Every time I wake up, I walk on the ground, and I have never seen anything coming out of the ground."

The whiteboard had already crossed the area where Wang Zi went to search during the day, and walked hundreds of kilometers away, which made Wang Zi open a new enclave map in the distance.

"Okay... I'll take care of it myself."

There is no useful information from the whiteboard, so Wang Zi can only put it aside for the time being. Anyway, there is already a safe house. When new materials are available in the future, the base will be transformed and sooner or later it will be built to create an invincible fortress.

After chatting with the whiteboard for a while and having dinner, Wang Zi said goodbye and went home and began to deal with things inside the base in a conventional manner, such as sorting out the materials collected, using the synthetic materials for two clever times today, and harvesting the monster material farms on each floor below. However, today there is a new content: inspect every corner of the base, especially the lower the farm, the more you look carefully, and strive to not let go of every corner.

In the next few days, Wang Zi's life became regular again. He went to say hello to the whiteboard in the morning, then flew out to search the building he was interested in, and moved it home when he saw useful supplies, while completing the task.

Then, after he killed another new ice monster, side mission 5 was finally completed.
