A miracle at the beginning

[Hint: The roller power energy collector can only be used by demon creatures]

Looking at the instructions on the scroll, Luo Yu smiled.

"This technology is simple to build, but the power generation is much more efficient than the hand-cranked generator."

"Ling'er, send a message to build this type of treadmill on a large scale in each county. Once I capture a large number of demon slaves, it can be put into operation."

"Write it down!"

Ling'er nodded with a smile and said, "My daughter thinks that the goblins on the front line can be transferred back. Let's build a hundred treadmills first, which can generate at least 50 million more energy every day!"

"50 million?"

Luo Yu said softly, "Silly, we can use the principle of leverage."

As he said this, he counted the water surface, and the pool water floated gently, forming a pattern.

"We only need to install seven or eight hand-cranked generators around a roller treadmill, and put bearings, levers and other things on the face, and they can work together."

"Although it runs slower, the power generation is doubled."

"One hundred million."

"Strive to achieve a small goal of one hundred million every day."

The beast maids were all slightly stunned, and their eyes showed a look of sudden realization.

It turns out that there is such an operation, I have learned it.

Xiaoduo raised her hand and said: "Master, if you run like this, those monsters will vomit blood!"

Shuang'er said softly: "Sister Xiaoduo, there is a lot of holy blood in the master's blood pool. You can add holy blood supply to the machine. Just drink a little bit to form a perpetual motion machine."

"It turns out that there is such an operation, I have learned it."

This was said by Luo Yu.

It must be said that Shuang'er's ideas are sometimes even inferior to his own.

Luo Yu said: "It is better to act than to be moved, baby, you send an elite team to go deep into the ancient cave area in the north to capture the ancient giants and tentacle monsters."

"Especially those ancient giants, they have big steps and run fast, and their power generation should be greater than that of goblins."

"I obey your orders."

Shuang'er smiled and nodded. Her master was always exploring and moving forward in capital operation, making progress every day, which made her extremely amazed.

Luo Yu looked at the description of the Fallen Light Launch Tower again.

This is a powerful turret of law-based attacks, which can make a large number of creatures within the attack range fall, be lazy and wait for death on the spot, or indulge in pleasure on the battlefield, etc.

Its power is so strong that it can even threaten the virtual god realm.

It's just that the law-based weapons consume extremely terrifying energy. The Fallen Cannon requires 3 billion energy each time it is fired.

At present, there is a shortage of energy, so it is better not to use it unless it is absolutely necessary.

Clicking on the description of the magic gas tank made Luo Yu's eyes light up.

The so-called magic gas tank can condense a kind of magic gas inside. The creatures immersed in the magic gas for a long time will gradually be demonized and transformed into our own units.

After being demonized, the wisdom decreases, and the combat power and endurance increase. As long as the time is long enough and the magic gas concentration is sufficient, even the top combat power of the Great Saint Realm can be demonized into our own units.

"Very good, this magic gas tank can be produced on a large scale. In the future, we can capture low-level creatures such as goblins and goblins and demonize them, and all exercise on the treadmill."

[Tip: Your elemental civilization has been promoted to 2.5]

[Tip: Your technological civilization has been promoted to 2.0]

"Humph, as expected, after unlocking more technology, the progress of civilization has been improved."

"The goal of breaking through the 5.0 level is not out of reach."

Luo Yu was satisfied.

Clicked on the building interface and prepared to build a large Demon King Castle near Yu City to accommodate these temporarily shameful demon technologies.

The site selection, planning, etc. were completed at four in the morning.

On the big bed, he yawned, holding Xiaokong and feeling sleepy. Suddenly, the divine pattern at the corner of his eye lit up, and a familiar voice sounded in his ear.

"My great doctor, are you asleep?"

"Huh?"

Luo Yu sat up, but saw a girl kneeling in front of him, with the same divine pattern on her face as his, wearing a green pajamas dress.

"Feisili! Why are you here?"

Feisili chuckled and made a gesture of silence, "Don't wake up the sisters."

"I miss you, come to see you."

Saying this, she held Luo Yu's hand, her eyes full of tenderness.

[Tip: Affected by the comfort of the healing goddess, your immunity +5%]

The goddess's little hands are white and soft, and her palms are warm and comfortable. Luo Yu suddenly lost all sleepiness.

He whispered, "I heard from Medusa before that the witches in the demon world are watching you. Once they come down to the earth to interfere with the normal operation of the lower world, they will trigger the heavenly rules and will be restricted by some rules."

"You are..."

"Huh? Did Medusa even tell you about this? She trusts you very much."

Feisili said softly, "Don't worry, this goddess has two god positions. With the current ability of the witch, I can only monitor one of them."

"Luo Yu, I came to you for something important."

"Qingluan came to see Medusa a few days ago and gave her a large sum of money. She said that she had agreed on a deal with you. When asked for details, she was vague."

"My Lord Medical Master, do you have any handle on the Kingdom of Zhouji?"

As he spoke, he handed a storage bracelet to Luo Yu.

[You get Tiandao coins: 1000 billion]

"Huh?"

"Huh, huh, huh?!"

Seeing the prompt, Luo Yu was shocked, and a huge joy rushed to his heart.

"Really gave it! So much money!"

Under the stimulation of one trillion, he couldn't help hugging Feisi Li and kissed the goddess' cheek hard.

A blush rose on Feisi Li's beautiful face. She let Luo Yu hold her, but waved her hand gently. The divine light rolled over, the curtains were drawn, and Xingguang could no longer invest a bit.

"You kissed me secretly again. If Sister Xingguang knew, she would be angry..."

Speaking so, he glanced at Luo Yu.

"Ying Tianheng is indeed a very talented artist. His artwork is so valuable!"

"Wonderful! It's really wonderful!"

"I feel deeply sorry for his death."

Feisili found that her lovely great doctor only had the storage bracelet in his eyes, not the healing goddess.

She was not angry, and her bright eyes always had a faint smile.

"There are countless choices in the long river of fate, and each choice will bring a different ending."

"It is because of his personality that we met in the secret realm and defeated Yuxi and Furong."

"Alas, when I liked him, it was already like this, and I can't do anything about it."

Thinking of this, Fesili chuckled softly, and suddenly threw Luo Yu on the bed with force, whispering in his ear: "I want you to hug me, hug me and I will go back."

[Tip: Affected by the comfort of the healing goddess, your attack speed +20%]

Fesili's initiative surprised Luo Yu.

He smiled and said softly: "If hugging means losing, then I would rather watch you from a distance."
