Ling Fan walked out of the stone gate and came to another stone house.

"Ahhhh

Screams echoed through the spacious stone house, high-pitched, high-pitched, high-pitched, short, or continuous, like a symphony of high tones.

The young man with thick eyebrows introduced to Ling Fan in a proud and proud tone:

"My lord, this is the foundation of the development of our Sin City, the 'Cradle of the Strong' laboratory."

"This way, please."

The thick-eyebrow youth led the way and led Ling Fan to a device.

The device consists of two parallel stone slabs 3 meters high, each with several levers attached to it that can be retracted freely.

In the middle of the stone was a muscular man, with a resolute face, as strong as a rock.

I saw that the lever was retracted, and the two stone slabs slowly closed towards the muscular man, and in the process, the muscular man's eyes gradually lost concentration, and his expression gradually collapsed as if it was broken.

"Ah!!h

The two stone slabs closed, and the muscular man let out a heart-rending scream.

The young man with thick eyebrows said to Ling Fan with great interest:

"My lord, please see, this is the 'anti-sharp strike device' that we have developed."

"These two stone slabs are plain on the surface, but their inner sides are covered with needle tips ten times thinner than a human hair."

"Every time the stone is clamped, it can produce a strong stimulation on the surface of the body, and after dozens of stimulations, the body will produce magical changes, and the resistance to sharp strikes will be increased to a certain extent."

The young man with thick eyebrows straightened his waist and said proudly:

"This device was praised by the lord of the castle, and it was very popular with everyone, and many people lined up to use it every day."

After speaking, the young man with thick eyebrows looked at Ling Fan with a look of hope.

The slate loosened, and the muscular man collapsed to the ground like mud, drooling from the corners of his mouth, and the whole person twitched twice from time to time.

Ling Fan smiled slightly:

"Yes, it's a genius idea."

The young man with thick eyebrows was very happy when he heard Ling Fan's praise, and led Ling Fan to another device.

"This device is an invention of the lord, and with the wisdom of adults, I guess I have already seen the purpose of this device."

Ling Fan saw crimson stones neatly arranged on the ground, and these stones were burning, emitting flames more than 1 meter high.

On either side of the stone stood two jade Y-shaped tubes, and on the tubes stood a long crystal tube, on which a man was tied to it, slowly turning above the flames.

Ling Fan said truthfully:

"It's a big barbecue grill no matter how you look at it."

"The wisdom of the adults is unparalleled, and I am impressed!"

"This 'Flame Resistance Training Device' was made by the lord based on the principle of a barbecue grill."

"These stones are red stones, which are the perfect materials selected from thousands of flame stones, which can emit flames evenly, and the flame temperature is just enough to maintain the body's proteins in a critical state that will be inactivated but not inactivated."

"And this crystal long tube, called the cool tube, can slowly and continuously produce a cold substance that penetrates into the cells of the body to repair the cells burned by the flames."

"In this way, after at least 10 hours of training, a person's flame resistance will be permanently increased."

"Yes, yes, very thoughtful, Si Pinsheng is really a whimsical and eclectic genius."

Ling Fan looked at the charred human body and nodded in praise.

Then, under the leadership of the young man with thick eyebrows, Ling Fan visited a series of device inventions such as "Blunt Weapon Resistance Training Device", "Ice Resistance Training Device", "Toxin Resistance Training Device" and so on.

The young man with thick eyebrows gave Ling Fan a detailed introduction to the materials, principles of action and effects of various devices.

These things were all secrets of Sin City, and the young man with thick eyebrows told Ling Fan all of them without reservation, which was obviously Si Pinsheng's instruction, showing his respect for Ling Fan.

"No wonder the elite troops of Sin City in the previous life were so fierce, all of them were like cattle, this is really a point of hard work, a point of harvest."

"It is worthy of Si Pinsheng, one of the few people who survived the Ten Thousand Races Arena in the previous life."

"A crazy genius scientist, no matter what world he is in, is a terrifying existence."

Ling Fan visited the various training devices with great interest, solved a little doubt, and satisfied a little curiosity.

After visiting the laboratory, the young man with thick eyebrows said respectfully:

"My lord, do you want to visit the territory next, or do you want to go back to your lodgings to rest, or if you have any other requests, please do not hesitate to ask."

"Give these things to Si Pinsheng, he knows how to do it."

Ling Fan said as he poured out a large pile of red fruits from the storage space.

These red fruits are full of grains and exude a strange fruity aroma that makes you feel energized when you smell them.

The thick-eyebrow young man widened his eyes, looked at the piles of fruits, and raised his tone by a degree:

"These fruits, can they be said to be blood fruits?!"

"No, no, these fruits are bright and transparent in color, and they are much larger than ordinary blood complex fruits."

The eyes of the thick-eyebrow young man widened, and he said in a lost voice:

"Could it be that these fruits are ten times better than the Blood Compound Fruit, and one fruit can refine a bottle of healing elixir...... Blood Rejuvenation Jade Fruit! ”

The young man with thick eyebrows was very excited, it was the first time he had seen such a precious medicinal material, and it was not one, but a large one.

"It's just some blood recovery fruit."

"As Si Pinsheng's side, you will be able to see a lot of materials that are more precious than the Blood Restoration Jade Fruit in the future."

Ling Fan said casually.

"What adults teach me is that I am losing my temper."

The thick-eyebrow young man restrained his expression and bowed to Ling Fan.

“？”

Ling Fan slowly typed a question mark, he didn't realize that his casual words meant any lesson.

"My lord, this is the video crystal of the seven-star mutant beast you fought against that day, a special version of the 10M resolution, specially made for you by the city lord."

The thick-eyebrow young man handed a crystal to Ling Fan with both hands.

Ling Fan nodded and took it, and then under the guidance of the young man with thick eyebrows, he passed through several stone gates in many turns, and finally walked out of the gate of the Lord's Mansion and came to the street.

It was the middle of the night, the moon was thin, and the streets were silent, except for the distant chirping of night owls.

"My lord, I'll take you to your lodgings to rest."

The young man with thick eyebrows took Ling Fan to a luxurious mansion, handed the key-shaped spar to Ling Fan, and said goodbye to Ling Fan.

Ling Fan went straight into the obviously newly built mansion, summoned a translucent levitating map, and entered his bedroom according to the marks of the mansion map.

"Let's see what happened at the end of that battle."

Ling Fan knew that he had won in the end, but by that time he had lost consciousness and didn't know what had happened at the last moment.

He activated the video crystal, and the crystal unfolded before his eyes......
