Mark raised the pickaxe in his hand, like an emotionless digging machine, digging and assimilating everything in front of him into cubes and putting them away.
Dirt, stones, concrete, and occasionally some ores can be dug.
He has no specific direction or target for digging. As long as he can dig, he will keep digging and harvesting.
"Crack!"
He didn't know how long he had been digging, but the area around Mark was already dark, and he could only vaguely see the outline of the object. The iron pickaxe in his hand also turned into square particles and dispersed with a gentle shattering sound.
"Crack!"
The sound of wood being inserted into the soil was heard, and the light from the torch dispersed the darkness around Mark and illuminated his strong face.
Mark clapped his hands, took out a piece of roast beef from the backpack space, and didn't care whether the ground under his feet was clean or not, he just sat down and started to chew on it.
It wasn't until he felt that his stomach was full and he opened his panel to check his satiety level that all ten chicken legs were lit up and ten red hearts were not wasted. Then he began to think about counting the types and quantities of cubes that had been mined and assimilated in the backpack space.
"One square, two squares, three squares..."
"One hundred soil, two hundred soil, three hundred soil..."
"One hundred stones, two hundred stones, three hundred stones..."
"A hundred ores..."
"Very good. If you keep digging for a while, your backpack will be full. Let's go back to the gathering place first and clear out all the blocks."
Mark smiled with satisfaction. Forty-nine of his fifty-spaced space backpack had been filled, and the last one was half filled, which amounted to more than 4,900 squares.
In addition to the three compartments dedicated to holding pickaxes, torches, and grilled steaks, more than 4,600 squares were also dug out.
Without hesitation, Mark patted his butt and stood up, took out a pickaxe again and dug to the side.
Not long after, Mark, whose backpack space was completely filled, finally stopped digging, put the pickaxe on his shoulder, and without taking back the torches inserted in several places, walked directly towards the path where the sparsely inserted torches came from.
Go forward, go downhill, turn, go uphill...
Mark walked around an unknown distance under the guidance of the torch, and finally came to a huge flat space filled with torches.
In all directions of this space, there are hundreds of tunnels dug like Mark.
Outside the space, there are tall and thick walls made of stone squares. Looking up at the top of the space, there is also a complete dome made of stone squares. I don't know how thick it is.
In front of each passage, there is a door shape directly sealed with glass cubes. There are no gaps that can be pried, and can only be dug directly.
Mark skillfully used a pickaxe to dig out the glass cube. After entering, he used the glass cube to seal the door again and walked towards his residence.
In the space, several areas with different functions have been planned, including those for planting trees, raising meat and livestock, growing fruits, vegetables and food, storing water and raising fish, processing food and tools, stacking boxes, building rest houses...
You can even see fenced-in passages in some places leading to spaces further below.
Of course, such a large space cannot be created by Mark I alone.
As Mark was walking, people came over to greet him from time to time, with a hint of gratitude and admiration in their eyes.
"Jack, you went to dig cubes too, right? How was the harvest today? How many cubes did you dig back?"
"Edward, you're not going to catch zombies again, are you? Stop wasting Assimilation Ring on zombies!"
"Mary, do you still want to eat grilled fish tonight? Can you change it to grilled chicken?"
"John, don't forget to continue digging a passage outside the city. Spider-Man Are you right about which direction their base is?"
Mark talks to everyone with a smile on his face, chats, complains, and arranges work, just like a qualified leader.
There are already hundreds of people in this huge space, all of whom have been assimilated by Assimilation Ring.
Some of these people were found by Mark when he was digging around in the city. There are quite a few people like him hiding in safe houses.
Some are zombies with wisdom rescued from the mouths of zombies, and some will not eat all the survivors they find at once, but will divide their hunting grounds like Beast divides the territory, and only grab a survivor to fill their stomachs when they are hungry.
Therefore, many survivors were not discovered by the zombies, but were kept captive by the zombies without their knowledge.
Of course, most zombies cannot suppress their desire for flesh and blood, so the survivors who are kept in captivity are considered lucky to a certain extent.
At least they still have a chance to wait for a future where they can start again.
Mark has been a military enthusiast in the past, and has especially studied the Earth Path war in the far east.
Therefore, after gaining the ability to dig at will, Mark, like the martyrs, placed the most important activity space under the ground.
During this period, he first used his basement as a starting point. After blocking the surface exits, he dug in all directions, and even dug a certain distance deeper.
In the following time, Mark continued to dig towards the center of the city, and expanded the digging area to the surroundings from time to time. All the excavated blocks were piled together in processed boxes.
Once a box is filled with 10,000 yuan, he will exchange Assimilation Ring for a new Assimilation Ring.
In this way, he dug, moved forward, and exchanged for Assimilation Ring. With the supplies in the basement, he had no problem of lack of food or drink at all.
During the excavation process, Mark occasionally dug back to the ground to observe the situation. After determining the direction, it continued to retract underground to dig.
Sometimes he would face zombies directly, but with the help of the assimilated huge strength and abnormally heavy weapons, even if he was besieged by hundreds of zombies, Mark could force his way out, and then quickly dig a passage in the ground to escape.
In the process, he dug through survivors' safe houses, rescued survivors who were being hunted by zombies, or found some survivors who had been kept in captivity.
So, Mark gave them the Assimilation Ring he had accumulated and asked them to dig around the city with him and rescue survivors.
As more and more survivors were rescued, and the number of assimilated survivors also increased, it was no longer suitable for one Legion person to run around underground.
So, after discussing it, they spent a lot of time digging and building the huge gathering place now in a place tens of meters underground where there were almost no zombies on the ground.
In the days that followed, they centered on this gathering place and dug in all directions. Even now, even they themselves don't know how many passages they have excavated.
Fortunately, with the coordinates on the panel, they can determine the location of the gathering place no matter where they are without fear of getting lost.
If someone could look through the city's underground, he would find that dense passages crisscross the city's underground, almost extending to less than half of the city.
