The moment Zhou Biao came in, he handed over the work at hand to others, and followed in with a few brothers.

When he saw Wan Lin take out the saplings out of thin air, as if playing a game, he planted all the saplings one by one, and his heart was shocked.

Although it is not too visible on the face, it can be seen from the inside of the eyes.

After Wan Lin finished planting the tree, he patted Zhou Biao on the shoulder, "Maintain the order!" ”

Zhou Biao nodded excitedly, Wan Lin's status in his heart has now risen to a new height, a height that no one can reach.

After Wan Lin did this, he walked straight towards the foundry, and he encountered more and more mutants along the way, which also made Wan Lin really feel that he was now building a place to accommodate human existence, rather than just a base for him to survive alone.

In the foundry, Wan Lin looked at the hologram in front of him and clicked on the mine, and the upgrade button on it was already revealed.

Wan Lin clicked on the upgrade button, and a box popped up.

"Tier 2 Mines (Upgradeable)"

"Upgrade Criteria:"

"Unlock the Silver Hoe;"

"Level 3 Mine Mining Blueprint*1;"

"Mining Bot*3;"

These conditions may not seem high, but they are simply impossible to achieve without completing the previous tasks.

Wan Lin hooked the corners of his mouth and clicked "Upgrade".

Then, a violent movement began.

All the mutants in the base area looked around in panic, and they all held on to people or objects around them to maintain their balance.

Wan Lin propped up the table, his eyes fixed on the mine.

I saw that the entrance of the mine cave was shaking violently, and the size of the entire cave was more than doubled, and Wan Lin could not see it underground, but it could also be roughly understood from the shaking ground situation.

The tremors were the most severe under the mines, then to the inner and outer cities, and then to the whole of Twilight.

The earthquake shook down many of the dilapidated buildings in Twilight, and the mutants in Twilight were shocked.

After the earth has suffered from energy mutation, there are even crustal changes!

But they didn't know that this earthquake was not a change in the earth's crust, but an upgrade of a tight mine.

"Ding! Side Quest - Level 3 Mine! It's done! ”

"Quest Complete Reward: Village Market Blueprint *1,4000 Radiance! (Available)"

Wan Lin excitedly clicked to receive the reward.

"Ding! Trigger the side quest - Bazaar! ”

"Quest content: There must be a market in the village, please build a market 0/1!"

"Quest Complete Reward: Shop Transfer Contract *10,4000 Radiance!"

Wan Lin looked at the prompt of the task, and after knowing that the level 3 base area must be to build a village, he could already imagine the future scene in his base area.

Bustling bazaars, bustling crowds!

Wan Lin subconsciously returned to the main interface of the base area, demarcated the outer city area, and clicked on the building column.

However, he found that the icon for building the Bazaar was gray, and he had not yet unlocked the conditions for building the Bazaar.

In other words, this task can only be seen but not eaten.

Wan Lin sighed and looked back at the mine.

In that case, he better complete the mining task first.

The next step is to explore the mine and light up all the areas on the drawings.

Wan Lin took out the level 3 mine mining blueprint in the bag, pinched it in his hand, walked out of the foundry, and walked towards the mine.

The current mine is marked with a level 3 sign, which is clear at a glance.

Wan Lin looked at the minecart at the entrance of the mine, and after the minemine was upgraded, the minecart was upgraded accordingly

The car has one more section and has become two.

There is a steering wheel on the front of the car, and there are brakes and forward gears underneath, which should be able to be operated manually.

The inside of the mine is bright, with lights installed on the top, and there is a clanging sound from time to time, which is the sound of mining robots mining.

Wan Lin jumped into the front of the car, put on the steering wheel, stepped on the accelerator to move into gear, and headed towards the mine.

While opening the level 3 mine mining drawing, he rested it on the platform above the steering wheel, and then looked at the drawings to determine the direction of driving.

A small red dot will be displayed on the mining drawing, which is the location of Wanlin, and will move according to Wanlin's movement.

As soon as I entered the mine, the surrounding scene was still somewhat familiar, but the area of the mine became larger, but as I slowly went deeper, the track became intricate, and more than a dozen holes linked together appeared.

Each hole has a paved track that allows the minecart to pass through safely.

Wan Lin, who was sitting in the minecart, also paid attention to the direction on the drawing.

The level 3 mine mining blueprint has 10 areas on it.

The drawings do not indicate a detailed route, but after Wan Lin passes through this area, he will be within a certain range of his body, and the drawings will be lit up to show a part of the road map.

Wan Lin didn't know what kind of exploration he had to complete in this area before he could completely light up this area.

This was a departure from what he had in mind.

Originally, he thought that as long as he passed through this area, or this line, this line would be lit up, but now after passing this line, this line is still not lit up on the map.

This made Wanlin's work of lighting up the map more difficult.

He scratched his head, could it be that there was still some task to be completed in the mine?

Wan Lin took his eyes off the drawings and began to carefully observe the situation around him along the way.

Suddenly, he hurriedly stopped the minecart, and he stared fixedly at a table in front of him.

On this platform, you can vaguely see that there is a track next to it, which should be the track entered by a certain hole, and there is a platform on the side.

But there was a copper chest on top of this table.

The platform over there is a little dark because of the cover of the wall, if you are not careful, you may miss it, and the platform is still on the branch line of the track, which is a dead end, and there is a cliff below.

Below the cliff is another track.

In this way, there is no track for this branch line to pass through.

This also makes this platform not easy to find, if it weren't for Wan Lin coming from a distance below the cliff and seeing this box from a distance, it would not have been found at the bottom of the cliff.

Wan Lin touched his chin and looked at the copper box of the platform above the cliff.

Could it be that the key to lighting up the area lies in this copper box?

Now that you've seen it, why not find out!

Wan Lin began to study the drawings with great interest, there are several routes around this, which one can lead to this cliff above?

Wan Lin cautiously drove a little further, and the drawings showed more lines.
