At this moment, a system prompt sounded in Wan Lin's head:

"Ding! Hidden Quest - Repair the Walls and Tunnels! It's done! ”

"Quest Complete Reward: Skill Level Up Scroll*1,4000 Radiance!" (Available)"

Wan Lin opened the task board and received this reward.

Skill upgrade scrolls?

He took out the reward he had just claimed.

It was a scroll made of parchment, and Wan Lin slowly unfolded it.

I saw a complex pattern drawn on the parchment, and a burst of light burst out in an instant, enveloping Wan Lin's body.

At the same time, a transparent virtual box appeared in front of him, which read:

"Upgradable Skills: Triggered Mine Trap, Deep Pit Stinger Trap, Thorn Path Trap, Elementary Mining Skill, Elementary Ore Smelting Skill!"

"Non-Upgradable Skill: Possessed by the Sun!"

"Please select the skill you want to upgrade!"

Wan Lin looked at the skills he could choose, a hint of joy flashed in his eyes, and then he quickly clicked on the skills that could save the most time for now.

Road of Thorns Trap!

"Are you sure you chose the 'Road of Thorns Trap' skill to level up? Yes/No! ”

Wan Lin chose "yes" without hesitation!

After he chose, the light in his hand began to flow slowly towards his body, as if the light was all integrated into his body.

After all this light flowed, the parchment in Wan Lin's hand had also turned into ashes.

"Ding! Upgrade Successful! ”

"Congratulations to the host for obtaining the first intermediate combat skill: Forest of Thorns Trap!"

Wan Lin couldn't wait to flip to his skill options to see his upgraded skills.

"Forest of Thorns Trap! Number of uses: 10/day, Cost: 10 brilliance/time! ”

I've used up the number of traps today, so I don't know if I can use them again.

According to the task content in the side quest - Improving the Battle Deployment of the Base Area (4), Wan Lin needs to complete the defensive trap arrangement 20 times, and now it has been completed 9 times, which is counted today.

Now it only takes 11 more layouts to get the blueprints of the primary combat robots, so that the next machine shop will not be idle there.

In the following time, a steady stream of primary combat robots will be produced.

And now the skill upgrade scroll comes just in time, which can raise his defensive trap to a notch, and directly complete this task in a few days.

Wan Lin was very excited, but he didn't rush to set up the traps, because even if they were finished now, there would only be 19 traps, and there was still one short!

As long as the traps are laid out today, you can produce a primary combat robot tomorrow!

Wan Lin slowed down his thoughts, thought of the robot being made in the machinery factory, and looked at his brain.

Recruitment ends at 8 p.m. every day, and it's already half past eight.

He had been working at 9 a.m. in the machine shop, so in half an hour, the transport railcar should be finished.

At that time, he will complete one more task, and by the way, he will also look at the role of transport rail cars and transport robots, which will also make it easier for him to decide what type of robots to produce in the machine shop.

He held back his excitement, walked out of the foundry, and first came to the spiritual spring water in the center, and filled the empty mineral water bottle on his body.

Later, he tried to pick some bread from the bread tree and eat it, but he found that the bread on the bread tree was not ripe.

At this moment, a voice sounded from behind him, "My lord! I have picked all the bread of your inner city and put it in the workshop. ”

Wan Lin turned his head to look and saw Yun Rou standing behind him.

Wan Lin smiled, bought a wallet from the mall, and hung it on the bread tree.

"In the future, you can put all the ripe bread in this wallet, and by the way, help me fill all those empty mineral water bottles with spiritual spring water and put them in this wallet."

"I'll change my wallet once in a while!"

Yun Rou immediately replied "yes"!

Wan Lin turned and walked towards the workshop, and he saw the pile of bread piled on top of the sheets, still in the same corner as before.

He walked and swept away the bread and put it all in his bag.

Then, he was not in a hurry to go out, but stood in front of the operation display screen and clicked on the warehouse.

In the past, only 3 batches of growth liquid have been made, but there are 9 bottles of 2nd grade growth liquid, because there are now three production lines for growth liquid.

Wan Lin took out 9 bottles of Level 2 Growth Liquid, uncorked all of them, and replenished the little sun above his head, and the growth value at this time had reached 1729 points.

After Wan Lin did this, he walked out of the workshop, patted Yun Rou on the shoulder, and walked towards the outer city.

Yun Rou silently followed behind Wan Lin.

After walking for a while, Wan Lin suddenly said, "By the way, did Xiaoxian tell you about the formation of an escort team?" ”

Yun Rou nodded and said, "That's it, just wait for Xiaoxian's affairs outside to be dealt with, and then go to the conference room to wait for you!" ”

"Let's go to the conference room in the outer city, you just recruited so many people, you still have to restrain yourself!"

Wan Lin looked at the brain time on his wrist, "Then it's set at 10 o'clock, I had two things last night, come over immediately!" ”

Wan Lin stood at the fork in the road to the machinery factory, stopped, and looked at Yun Rou, "You and Xiaoxian, bring the people you think are suitable to enter the escort team among the newly recruited mutants, and come to the meeting chair together!" ”

"Yes!"

Yun Rou watched Wan Lin turn around and walk towards the back of the machinery factory, and she didn't know what she was thinking.

Wan Lin walked into the machinery factory and opened the operation display, on which the three progress bars were full.

Wan Lin first clicked on the mining robot, bought a schoolbag and equipped it, set up a series of commands, and went out of the warehouse to the mine.

Then there are transport robots and transport rail cars.

The transport robot Wan Lin was not in a hurry to collect it first, but clicked to collect the transport rail car first.

This time, the transport rail car showed no mountains and no water on the production platform, and Wan Lin only saw a 2-meter by 2-meter cube.

Wan Lin chose to leave the warehouse and directly clicked on the transportation track.

"Ding! Meet the conditions for transporting rail cars out of the warehouse! Retrofitting! ”

Wan Lin saw that four manipulators stretched out from the circular chassis to load the 2-meter by 2-meter cube, fix it with ropes, and then transport it into the transportation channel.

Wan Lin quickly ran out of the machinery factory, scurryed to the roof of the machinery factory, and looked between the smelter and the mine.

I saw that the circular chassis flew out of the warehouse platform and flew directly towards the door of the smelting workshop.

Not far from the entrance of the smelter is the end of the transport tracks.

The circular chassis landed at the end of the transport track, and the 2-meter by 2-meter cube was placed directly on the transport track with a manipulator.
