"Jiang Beichen shot and directly sealed several people's acupoints.

The scene was momentarily silent.

Jiang Beichen glanced at many prisoners with a cold look in his eyes.

"Shut up, or you won't be able to eat in prison!"

Jiang Beichen's eyes are terrible. Even if these are the most heinous criminals, they are immediately restrained by Jiang Beichen. There was a look of fear in his eyes.

Jiang Beichen saw that no one dared to shout again, so he took Qinglin and them to go inside quickly.

They must find them in Tsing Yi quickly, or they will be found too late.

However, at last, in the innermost part of the prison, Jiang Beichen found the figure of Qingyi.

This is a dark and damp cell with rat excrement in it. The sanitary conditions are very poor, and dozens of thin girls are hiding in the corner with their heads trembling.

The biggest one, the girl in wedding clothes and unkempt face, burst into tears when she saw several people.

"Brother, brother Jiang, sister Tang, I'm not dreaming, am I? You finally came to save me!" Qingyi couldn't help choking with excitement.

These days, she has encountered too much.

I watched my father aooka die in front of me.

When he was regarded as the object of Yin marriage, he forced Liao ming to worship heaven and earth.

Then they were dug out from the tomb and brought to the prison of the blood witch family.

Panic, grief, despair, in this dark prison, days and nights, she did not know how she survived.

"A Mei! A Mei! Don't worry, big brother. I'll save you now!" Qinglin was so excited that he hurried forward to break the shackles of the cell.

But he tried his best, but he still failed.

Jiang Beichen hurriedly took a step forward and said with flashing eyes, "this is Beiming dark iron. Ordinary sharp weapons are difficult to cut!"

"What should I do?" Tang Zhiruo thought of something. Hurriedly ran to the other end and searched the prisoner's body. I thought I could find the key.

But I don't want to miscalculate. The key is not on the prison head at all.

Qingyi kept biting her lips and said bitterly, "brother Jiang, don't waste your energy. These people just work for the priests, and the key is not on them!"

"I'll come!"

Jiangbeichen secretly transport power, ready to use absolute force to break the door lock.

At this time, an old and joking voice suddenly came from a nearby prison, "young man, I advise you not to do that!"

Jiang Beichen frowned and slowly turned to look. He saw a white haired old man sitting on the straw mat in the prison.

At the age of 60, he has a goatee, dry and thin, but his eyes are unusually hale and hearty.

Jiang Beichen couldn't help frowning and asked, "who are you and why do you say that?"

Intuition told him that the old man was not simple and definitely not a passer-by.

Sure enough, the old man sneered and said proudly, "why do I know? Hehe, the whole blood witch city was built by people of our Mohist family. How do you think I know!"

"Mohism?" Jiang Beichen's eyes were slightly moved.

Mohism, in history, is a famous leader in the field of exquisite mechanism.

Mozi, the founder of kaipai, is one of the most famous schools of thought.

Although he was not famous for his non attack and universal love, he was also very popular at that time.

Even many kings took him as their guest of honor.

For Jiang Beichen, one of the historical figures he most admires is Mozi, who is good at craftsmanship, and the other is Guiguzi. Both of them have a far-reaching impact on him.

"It's a master of Mohism!" Jiang Beichen hurried forward and arched. He has no doubt about the other party's words. Now he can see through a person as soon as he opens his eyes.

He knew that the old man in front of him would not lie.

Just to his surprise, as a descendant of Mohism, why did he appear in the prison of blood witch family.

Seeing Jiang Beichen's respectful attitude, the old man's face eased a little. Just as he was about to speak, there was a sound of riots outside.

He suddenly changed his face and hurriedly said, "this is not a place to talk. I'm waiting for you here. Now that you're here, it means that the blood witch bastards are exhausted!"

"Even if I work hard, I will never let these bastards succeed!" The old man couldn't help laughing wildly.

Immediately he quickly bowed his head and shouted solemnly to Jiang Beichen, "young man, do you understand Qimen gossip?"

"A little understanding!" Jiang Beichen nodded quickly.

"What one or two? What's so modest at this time!"

“……”

"Listen to my password!"

The old man looked serious and shouted, "now, take the green brick under your feet as the astrolabe, and you walk according to the eight trigrams!"

"If there is an eight point risk when closing the door, there will be no Yang eight trigrams. The ridge is separated from the earthquake and divided into four elephants, and the heaven and earth are Gen Xun Han!"

After listening to the old man, Jiang Beichen's eyes brightened, and a star chart appeared in his mind. Suddenly, his steps were linked, and he stepped up quickly towards the green brick.
