In the tomb-guarding beast prison, facing Mo Zi's wooden kite mirrored tomb-guarding beast, the "animation" imaged by a small hole on the underground palace wall, Qin Beiyang almost thought he was killed by arrows.

The light and shadow on the wall change rapidly, as if the slides were removed. It was no longer an archery crossbow, but a solid city gate fortress. Then it turned into an orange hanger that drew water in the countryside, and then to the old carpenters who drew square rectangles, circular plaques, straight ink buckets, and flat-scale hanging hammers... They were all inventions of Mo Zi and are still used in various parts of China today.

Qin Beiyang twisted his head and looked at Xiao Kong's reflection, almost breaking his neck. When he was nine years old, he was confined to Emperor Guangxu's underground palace, and he learned the most basic tools of these craftsmen's craftsmen's work with his father.

"Mozi drew the things he invented, bellows, siege crossbows, and various machinery into animations similar to the lanterns, and stored them in the mirror of the wooden kite mirroring the tomb-suppressing beast. As long as there is light, it can be used to image and project the image... Our ancestors were so great!"

Qin Beiyang exclaimed, and the ghost mask replied calmly: "It also makes us descendants too incompetent."

"Why did such a good thing not pass down in later generations?

"The skills of the wooden kite are only in the hands of a few people, such as Mozi's disciples. Although they have no political ambitions, they master a lot of skills of war and fighting. In the eyes of the Warring States monarch and Qin Shihuang, they are all great threats, so they must be wiped out. So much so that the common people only know that there is Lu Ban, but not Mozi."

The ghost mask sighed and took down the wooden kite mirror spinning in the sky like a tomb-controlling beast. More than ten ancient bronze mirrors returned to the belly of the wooden kite, spread their wings and flew back to the cave at the end of the underground palace, closed the solid iron door again, and fell asleep in the dust of history.

"The various schools of thought, Confucius and Mencius, Laozi and Zhuangzi's teachings, Han Fei's teachings, and Mozi's skills are far more than the art of craftsmen!"

"Beiyang listen carefully."

"This has exceeded the scope of learning in the 'underground palace'. In the words of modern university, it is 'out of the syllabus'! If you have the chance in the future, I will explain it to you in detail!"

Qin Beiyang's view on the ghost mask has completely changed: "Teacher, for me, this is a night of transformation."

"I am very satisfied with you because you have this heart. But this night is far from over! Beiyang, come with me again!"

The ghost mask took him through a stone door at the end of the underground palace. There was actually a second underground palace, and countless torches lit up again.

This is a huge circular space. Compared with the square underground palace just now, it reminds people of the "round and round sky". Qin Beiyang stood high on the edge of the underground palace, showing concentric circles falling continuously, and at the bottom is a circular loess site. He saw the bronze prints of the ancient Roman Colosseum from Professor Wang Jiawei's collection, which looked exactly like the shape of the underground palace in front of him.

In the Colosseum in the underground palace, the Ghost Mask Professor talked: "There were slave gladiators in the Xia, Shang and Zhou dynasties. They fought with wild beasts and fought with each other. The winner continued to kill, and the loser died on the spot."

“This is cruel!”

"In ancient times, the acceptance of the tomb-suppressing beast was adopted by the living gladiator. If the gladiator was killed by the tomb-suppressing beast, it means that the tomb-suppressing beast was qualified. If the gladiator was still alive and even defeated the tomb-suppressing beast, the gladiator would be restored to freedom. The tomb-suppressing beast was not up to standard, and the tomb-suppressing beast would become a slave, or even become a gladiator and die."

Faced with the ghost mask talking, Qin Beiyang was puzzled: "How do you know the past of the tombsman clan and the tomb-suppressing beast?"

"Now, I am your master, just listen." The ghost mask took his hand and walked to the edge of the Tomb-Suppressing Beast Colosseum. Under the platform was a battleground with blood and yellow sand. "The cruelty of the underground palace road is far beyond the Assassin's Way. The cruelest thing is to learn to fight with the Tomb-Suppressing Beast in the last level before graduation!"

"Unbelievable, you train the schoolchildren to become tomb-suppressing beasts? The children will be eaten by tomb-suppressing beasts!"

"Any school will have an elimination rate, and there will always be people who cannot graduate. Twenty years ago, there were still imperial examinations in China. Those who could be selected for the imperial examinations in the palace to meet the emperor, but only a few people. Many people studied hard every night until their hair turned white and were still taking the exam for scholars! The Age School must select the best, and the rest can only die for themselves."

"Or died at the mouth of the tomb-suppressing beast?"

Qin Beiyang revealed the greatest possibility, and the ghost mask smiled indifferently: "I'm sorry, this is our destiny."

"Teacher, you were also a school child at the time. You passed five levels, killed six generals, and finally graduated with an excellent student?"

"yes."

The eyes behind the mask flashed, and a sharp and long roar like a monkey was made.

Under the ground of the Tomb-Suppressing Beast Colosseum, several iron doors opened, followed by fierce roars, and the unique smell of the Tomb-Suppressing Beast hits the face.

A bronze tiger with white eyes hangs and white forehead first rushed to the Colosseum and heard a deafening tiger roar. The metal tiger whip slapped the ground, stirring up waves of yellow sand.

"Tiger tomb-controlling beast!"

Before he finished speaking, he saw a stag, holding the snow-white antlers of the same color as the nine-colored ones, and four thin hooves supporting the bronze body, and actually jumped over the tiger's head.

Bucks tomb-suppressing beast.

In a blink of an eye, a third tomb-suppressing beast came to the Colosseum. This time it was a black bear, with its staggering and heavy body, and every step it took would shake the underground palace. It stood up like a person, exposing the white crescent moon on its chest, and slapped its chest with its claws.

Black bear tomb-suppressing beast.

There was also a fourth one, but a golden ape, rolling on the ground and climbing the walls of the Colosseum. It saw Qin Beiyang and grinned at him.

Apes and monkeys tomb-suppressing beasts.

The last one did not come out from the ground, but from the ceiling of the circular underground palace. A whole wave of heat was curled up in the air, and Qin Beiyang's hair was curled up. Only then did he see a pair of black wings making the sound of crows, like a black bird that was reporting death, slowly landing and actually stopped on the back of a tiger.

Ghost Mask answered Qin Beiyang first: "Crow tomb-controlling beast."

The Colosseum of Tomb-Suppressing Beasts gathers five animal-shaped tomb-Suppressing Beasts.

Qin Beiyang saw so many tomb-controlling beasts entangled together for the first time. Five spirit stones emitted heat at the same time, making the underground palace storm like a steamer already in midsummer.

"What kind of tomb-suppressing beast is this?"

"The miraculous doctor Hua Tuo."

"Hua Tuo from the Three Kingdoms? Hua Tuo who scraped his bones to heal Guan Yu?"

The ghost mask nodded slightly: "Not bad! Forty years ago, we dug Hua Tuo's tomb and found that there were five tomb-controlling beasts, which were tombs built by Emperor Wen of Wei Cao Pi for Hua Tuo. Because Hua Tuo used Mafei San to perform surgical operations on Cao Pi during his lifetime, he saved his life."

"Didn't Hua Tuo be killed by Cao Cao?"

"Well, Hua Tuo treated Cao Cao for illness and suggested craniotomy and general anesthesia with Ma Fei San. Hua Tuo invented the earliest anesthesia technique in the world, using Chinese herbal medicine as the raw material formula, which is a great progress in the history of medical science. Unfortunately, Cao Cao did not believe Hua Tuo, and thought he was here to murder him, so he put Hua Tuo in prison and killed him. The formula of Ma Fei San was lost, which was a pity! Soon, Cao Cao, a generation of heroes, died of illness, leaving behind seventy-two suspicious tombs."

Qin Beiyang glanced at the Colosseum: "What do these five tomb-suppressing beasts mean?"

"Your life and death field!"

Before he finished speaking, the ghost mask flew up and kicked Qin Beiyang in the vest, causing him to fly out of the guardrail and fall into the Colosseum of the Tomb-Suppressing Beast.

Five tomb-guarding beasts rushed to jump up to welcome the midnight snack... "ahloh!"
