Chen Wangping thought for a while and had not yet come up with the most suitable purpose, so he could only throw the giant robot circuit board into Taichung to choose analysis and look at the drawings before talking about it.

【The analysis of giant robot circuit board is expected to take one hour】

Seeing that it only took an hour, Chen Wangping nodded and walked to the wooden storage box next to him with great anticipation.

He took out the first-level mechanical crystals and carefully took stock of them. Including the newly created in the past two days, the number of first-level mechanical crystals has reached 513, which is enough to upgrade production technology!

Finally saved enough!

He couldn't wait to open the technology tree and chose production technology to upgrade.

【Congratulations on successfully upgrading production technology】

[You unlocked the production series [Petroleum Refinery] drawings, [Chemical Factory] drawings, [Magnet furnace] drawings]

This time, only three drawings were given away, but all three were drawings that Chen Wangping urgently needed. He couldn't wait to check the method one by one:

【Petroleum Refinery】

【Usage: Refined Petroleum】

[Material: [Circuit Board] × 20, [Gear] × 20, [Pipe] × 10, [Steel Plate] × 50, [Stone] × 20]

[Building method: secondary manufacturing station]

[Note: Petroleum refineries have high pollution and high ventilation requirements]

【Chemical Factory】

【Usage: Use petroleum to make petroleum products】

[Material: [Circuit Board] × 20, [Gear] × 10, [Pipe] × 40, [Steel Plate] × 50]

[Building method: secondary manufacturing station]

[Note: Chemical plants are polluted greatly and the ventilation requirements are also very high]

【Energy-saving drawings: magnet furnace】

【Usage: Magnet production】

[Material: [Steel Furnace]×1, [Magnetic Coil]×40]

[Building method: secondary manufacturing station]

[Note: Large-scale equipment that does not have magnet furnaces that cannot be placed near magnet furnaces]

After reading the two drawings related to oil, Chen Wangping frowned.

Both of these things are very polluted. If you continue to put the underground river, it is very likely to break the balance of the power generation environment that has finally been created.

No, I have to change the place.

Chen Wangping glanced at the back mountain, thinking that he might as well make a wall in the back mountain and put out the oil refinery and chemical plants in the open air.

There should be no problem doing this in a short period of time.

After all, these two things are very consumable, and steel plates alone cost hundreds of dollars, so it is not easy to expand the scale.

"There are so many consumables, so the effect must be very good."

Chen Wangping took out the materials and placed them on two secondary manufacturing platforms, and chose to make them one by one.

[The petroleum refinery is under construction, and it is expected to take five hours]

【The chemical factory is being built, it is expected to take five hours】

Chen Wangping frowned at the prompt that appeared, "The construction of such large buildings has been a bit long. A manufacturing machine can only be used for more than four machines a day with full power."

He glanced at the first-level energy-saving plug-ins collected from the technology tree, thinking that since there are energy-saving plug-ins, maybe there will be efficiency plug-ins in the future. Let's study it later.

Retracting his thoughts, Chen Wangping glanced at the magnet reserves.

After creating these five hundred first-level mechanical crystals, there was no magnet at home.

He had no choice but to pick up the lightning-striking ironwood pickaxe and ran towards the magnetite.

Hurry up and dig some magnets and shoot a few magnet furnaces to see the effect.

After arriving at the mine, Chen Wangping skillfully picked up the mine pick and pointed it at the large magnet and smashed it. After drinking the body-strength supplement, his current strength increased by a large part. With one pick down, he could create a large hole, and his efficiency increased exponentially.

Not to mention, the feeling of smashing the mine is quite good. The more he smashes, the more he feels the sudden increase in his body's strength, and he feels comfortable all over.

At this moment, in the black oil ruins.

Tang Xihe, who led the team to explore the medical department, was in a fierce battle at this time. Her enemy was a group of human-shaped but fearless monsters. Each monster had many long tentacles all over its body, which looked extremely annoying, but it couldn't be killed.

It was obvious that it was about to be killed, but the monster was slippery. Once seriously injured, it immediately fled back with the help of the grab of the tentacles. After a few minutes, it jumped out again.

Fortunately, these monsters are not very powerful in combat, and their tentacles are not as powerful as those mutated octopuses outside. The battle situation is in a stalemate. If you continue to drag on, Tang Xihe will definitely return in vain this time.

The commander of the city guards who led the team shouted loudly: "Miss, should we quit? Brothers are all tired, and this ghost thing can't be killed!"

Tang Xihe glanced at the watch and suddenly remembered what Chen Wangping said. She quickly explained: "Everyone took out the windproof mat and tincture oil they carried when they set off in the morning. I will listen to my orders and kill all these monsters later."

Although the commander of the city guards did not understand, he nodded immediately, "OK!"

Tang Xihe stared at the watch and waited for thirty seconds. As noon arrived, a huge gust of wind suddenly blew from various places in the black oil ruins that had not been windy.

The Medical Department is no exception. The violent wind blew along the entrance of the Medical Department towards the interior of the Medical Department.

Tang Xihe was overjoyed, "It's now, throw away the tinder oil!"

The city guards wrapped in windproof mats raised their hands and threw large buckets of turmeric oil at the monster in front of them.

Before these monsters could react, Tang Xihe took a deep breath, the ruby ​​on his chest suddenly lit up, and his hands pushed horizontally towards the monster!

Instantly.

Hundreds of surging little fire snakes carried the wind, wrapped in tincture oil and blew towards the monster.

In just a blink of an eye, these little fire snakes grew in the wind and instantly turned into five meters long fire snakes. The fire in the medical office was shining and the temperature soared.

"Go to die for me!"

Tang Xihe gritted her teeth and controlled the uncontrollable huge fire to smash towards the monster, instantly igniting all the monsters present.

"Tear and pull!"

The hot wind blew, and these monsters were instantly dehydrated, and then they were ignited by flames, turning into fire balls, and then turned into ashes.

The strong wind came and went quickly, and disappeared in just a few dozen seconds.

When the strong wind disappeared, the ashes of these monsters were lifted up, and the scene was immediately cleaned.

The commander of the City Guards, like other City Guards, was stunned. He saluted Tang Xihe from the bottom of his heart: "Miss is a great idea, and Fire takes advantage of the wind to destroy the enemy with one blow!"

"Miss is a great idea!"

"So amazing! More powerful than the city lord!"

"The city lord is too old, so he will still have to look at the eldest lady in the future!"

Tang Xihe looked at everyone and smiled, waved her hand and said, "This is not what I calculated, it was Chen Wangping told me in advance. Okay, now the monster is destroyed, let's continue to explore and get some good things back."

"yes!"

The city guards shouted in admiration and walked excitedly into the line.

Tang Xihe walked behind, recalling the huge fire just now, nodded with satisfaction, thinking that Brother Ping is so powerful that he could even calculate such a sudden strong wind.

However, why is his thunder and lightning superpower so complicated? He knows everything?

Could it be calculated through magnetic fields?

I'm so curious, I need to ask in detail when I look back.

Two hours later.

Chen Wangping was still immersed in the joy of digging magnetite, one after another.

Suddenly, he saw a series of white lights emerging from outside the magnet mine cave in the aftermath.

Chen Wangping turned his head and looked at it, feeling happy, "The gem mine has been released again? White light? Is it a new variety of gems?"
Chapter completed!
