The Mohist mechanism city is built in the mountains in the north of Jimo City in the state of Qi. It is surrounded by mountains and rivers on three sides. Easy to defend but hard to attack.

Mo Zhai, the founder of the Mohist school, was even more proficient in the art of guarding the city, and the mechanism city was built by Mo Zhai after exhausting his whole life.

Mohist founder Mo Qu has always adhered to the principles of "universal love" and "non attack" and opposed all aggressive wars.

As long as they come to the Mohist school, whether they are fugitives or traitors, they will be taken in.

Over the past few decades, the Mohist ideas of "universal love" and "non attack" have spread to every corner.

Together with Confucianism and law, it is called "outstanding learning in the world".

After entering the mechanism City, the rosefinch landed and stopped, and a dazzling light suddenly shone on it.

"Password!" a voice came from above.

Old man ban immediately replied, "tie the world and love all sentient beings."

The man above replied, "go to the soup fire and pound the sharp blade."

"Who's down there?" suddenly the man above shouted.

"Lao Feng, it's me, Miss Rong, yue'er and the leader, and two guests of the leader." old man ban immediately replied.

"The big leader is there, too. Understand! Strong crossbow ramp, let go." after the man finished, the slate was closed, and there was darkness around. A little light flashed overhead, and then more and more.

After seeing it at dawn, he said, "look! What's that? You can see stars in the mountain. It's fun."

"If you knew what it was, you wouldn't think it was fun," said old Ben.

"Then what are you talking about?" said Tianming.

"This is the first line of defense of Mohist mechanism city - strong crossbow array. If the enemy invades or fails to answer the export order, the strong crossbow array will be launched," explained master yue'er.

"You mean these white dots are a lot of bows and arrows!" Tianming said.

"Well, it's very sharp. Have you seen the ice sugar gourd string?" said the old man.

"Er... Yue'er, what machine did you say here? Mechanism city?" he shivered behind Tianming, quickly changed the topic and asked again.

"HMM... the Holy Land in the eyes of Mohist disciples is also the most confidential fortress of Mohism - mechanism city." yue'er explained.

"You mean..." before the dawn finished, old man Ban said again: "sit down! We're going to the city."

After a while, the sound of gear rotation came from the darkness, and a stone gate slowly rose not far away. Through the stone gate, bright light came out. The light shone on everyone's faces. Everyone showed a happy smile and swept away the fatigue of running recently. As the rosefinch approached the stone gate, the light became brighter and brighter, and finally annihilated everyone together.

………………

In the majestic Xianyang palace.

"Mohist mechanism city?" in the bright sun, Ying Zheng, dressed in a crown suit, pressed the hilt of the sword at his waist with one hand, looked ahead and frowned slightly.

"That's the most secret fortress of Mohism and the safest hiding place for rebels everywhere." next to him, LISS lowered his head and said respectfully.

"There is a place beyond the control of the law of the Qin Dynasty in the land of the Qin Empire." Ying Zheng's eyes flashed coldly: "what's the reason?"

"The Mohist mechanism city is hidden in the mountains. The terrain there is strange. There are steep cliffs and deep valleys for hundreds of miles. It is difficult to climb even with light bare hands, let alone soldiers and troops in armor." LISS continued: "The turbulent river water is surrounded below. There are hidden reefs and rocks in the water. Ships often hit the reef, ships are destroyed and people die. What's more strange is that there is an unpredictable sea of clouds. The climate is sunny and rainy. Walking in the mountains, you often lose your way in the vast sea of clouds."

Hearing this, Ying Zheng said strangely, "Oh, since the terrain there is so dangerous, how did the Mohists build a fortress there?"

LISS explained: "when Mohist school was founded 400 years ago, it was good at mastering mechanism skills. It is said that this mechanism city has a dangerous terrain, very hidden, exquisite design and complex mechanisms. It was built by Mohist disciples for many years before and after hundreds of years."

"It took hundreds of years to build it, that is to say, the Mohists began to build this fortress long before the Qin Dynasty unified the world?" Ying Zheng asked.

"Exactly."

Ying Zheng added, "what is their purpose?"

"Those rebels claim that years of war will eventually destroy the world, and this city will become the last paradise for people to avoid war and enjoy a happy life," LISS said.

The winning policy was silent for a moment. Slowly, "seven hundred years ago, the world has been torn apart, and the power of every country has split up. People have different languages, different language habits, different living habits and different traditional beliefs, so they will fight for war, and they have not stopped for a full seven hundred years." "The reason why I want to destroy the six countries is to eliminate these barriers. There is no division of national boundaries and no misunderstanding of language. Only then can people live together harmoniously. Only in this way can such a country be qualified to be called a paradise."

"Since your majesty Cong unified the world, there has been no war for five years." LISS turned his head to Yingzheng and complimented him.

Ying Zheng was a flash of cold light and said: "between heaven and earth, it is the land of the great Qin Dynasty. The people living in this land are the people of the great Qin Dynasty. In my empire, there is absolutely no place like the Mohist organ city."

There was silence in the huge Xianyang palace, and only the cold voice of Yingzheng echoed constantly.

………………

"Bang..."

The organ bird passed through a tunnel and landed on a prominent rock platform.

Below the platform is a lake, which occupies most of the area of the natural karst cave. It is illuminated by the sunlight from the dome, just like a huge blue gem.

Around the lake, there are countless stalactites and stalagmites in various forms. They are dazzling and colorful. Drops of crystal water fall from the stalactites. Some beat on the ground or stalagmites to make all kinds of ethereal sounds, such as playing fairy music. Some fall into the lake and ripple in circles, reflecting pieces of sparkling light and shadow, It seems that the whole space is shaking slightly, just like a dream.

"Wow, it's so handsome. There's such a place in the belly of the mountain." Tianming first jumped down from the wooden kite, jumped left and right on the platform with an amazing face, and looked at the surrounding scenery.

Mu Hantian also came down from the rosefinch with yue'er in his arms. Duanmurong and Nongyu stood on both sides of Mu Hantian respectively.

"The boy really hasn't seen the world. It's just the beginning. He's so excited." master ban looked at the dawn and scurried around. Although he looked a little disdainful, he was very complacent. He stretched his waist and sighed: "it's great that every time he comes back here, his mood will become very calm and there is no danger of chaos outside."

"The feeling of returning to 'home' is very good." Mu Hantian rubbed Yuer's hair and said with a smile.
