Below the square cave entrance, there was a bright fire and shadowy figures.

Above the entrance to the fourth room, three big resentful beings looked at each other gloomily.

"Aren't you always running in the front?" Yu Hongdou didn't dare to look at her teacher. She turned to look at Tan Langxiu who was forced to stay on the ground to protect them.

"..." Tan Langxuan didn't say anything, but just stared at Yu Hongdou with some deep eyes.

Yu Hongdou felt a little nervous when being stared at. She looked around uncomfortably and finally set her sights on the teacher who had a gloomy face.

"Teacher, don't be angry. We all have to go down in the end anyway." Yu Hongdou whispered to persuade Mo Shougui, who had just been picked on by his brother like her.

This irritated Mo Shougui, and he glanced at her: "I could have gone down, but they didn't understand the mechanism. It was because of you that I didn't go down."

What a lie! Mingming's brother and Tan Yanlin said they wanted to ensure the safety of her and the teacher, an old man and a child, so they didn't let them go.

However, Yu Hongdou swallowed her words as she looked at Mo Shougui, who was rarely showing his displeasure in a childish way.

The two door gods were not easy to deal with, and it was no fun to deal with Qian Sanmei and Mo Ding behind him, so Yu Hongdou simply stuck his head into the cave and stared at the situation below.

Tan Yanlin and Yu Song below had already fallen to the ground.

"Sir, it seems that someone has lived here." The first guard who came down had already walked around the secret room and came to report.

"Well, is there an exit?" Tan Yanlin nodded, not surprised at all.

Didn’t Hongdou say before that the person who captured her would live here?

The guard shook his head, indicating that he didn't see any exit.

Tan Yanlin did not show any disappointment. If the exit appeared so simply, he would have been suspicious.

Compared to Tan Yanlin's calmness, Yu Song was a little concerned: "Are there any daily necessities? How long have you been looking at them?"

When they came in, apart from opening a few secret rooms, they hadn't seen any other mechanisms or devices. How come their way was suddenly blocked?

Yu Song suspected that someone was living here secretly, and had discovered and followed them, and was doing something bad behind their backs.

"It should be quite old, but it's well preserved. There are some messy handwritings on the wall, which I can't understand." The guard did not ignore Yu Song and answered all his questions one by one.

Yu Song walked in the direction the guard pointed, staring at the white characters and marks on the ground and walls and frowned.

He couldn't understand most of them, but there were a few places that Yu Song had seen before. When his sister was studying with Master Mo, he also attended several classes and had seen many marks called "formulas".

"I'll go pick up Master Mo and Hongdou." Yu Song turned around and greeted Tan Yanlin.

Tan Yanlin stared at the marks on the ground and walls in a daze. He knew more than Yu Song, but there were still most of them that he couldn't understand.

Mo Shougui and Yu Hongdou followed quickly, while Tan Langxu continued to stay up there to guard. Before they found the way down, they couldn't all take risks to avoid being forced into a trap.

"It's a formula!" Yu Hongdou looked at the scrawled characters on the ground and walls in surprise.

Not just formulas, but formulas from different subjects, mathematics and chemistry.

"These are numerology, as if they are verifying something. Those... look a little strange." Mo Shougui shook his head at the wall.

The mathematics and geometry contents passed down by Mohist ancestors were all unfamiliar to him and were obviously not within these two fields.

It's chemistry, Yu Hongdou answered quietly in her heart.

Her chemistry grades were average, but the chemical formulas in front of her were not particularly advanced, just with very illegible handwriting. Yu Hongdou struggled to recognize two of them.

One is the reaction formula of iron and concentrated nitric acid, and the other is the reaction of iron and dilute nitric acid.

There were a few more guesses, most of which were reactions of x and xx. Thinking of the hat fairy asking Mi Sheng to recite the periodic table, Yu Hongdou became excited.

Could this be a new student found by the hat fairy who taught Mi Sheng? Or, is this the hat fairy who taught Mi Sheng?

"I suspect that this is the trace left by the new disciple of the hat fairy who taught Mi Sheng." Before Yu Hongdou could express his guess, Tan Yanlin spoke out first.

Mo Shougui was stunned for a moment before he remembered who Mi Sheng was. He had not heard the storyteller tell this story in person, so he did not have a very deep impression of Mi Sheng and only remembered the hat fairy.

So he reasonably guessed: "What if this is the hat fairy who taught Mi Sheng?"

Yu Hongdou strongly agreed with the two people's speculations. Yes, she thought so too.

The three of them looked at each other, put aside the formulas on the floor, and looked at the traces of life.

The terrain here is the same as the hall above, both are square outside and round inside. The place where they are now should correspond to the [Qian] gate above.

[Qian] is represented by three horizontal lines, which should be in the secret room of this underground palace. There are three door walls, and there should be no path on the last wall.

So this wall became a "blackboard". Perhaps the people who calculated on the blackboard were a little obsessed with it, and placed a lot of daily necessities at the base of the wall.

Over time, these daily necessities have accumulated a lot of dust and are piled together in a mess, just like the bedding of a homeless person.

Yu Hongdou frowned and didn't dare to use her hands, so she had to kick the pile of junk with her feet. With this kick, the piled things suddenly scattered.

Yu Hongdou stared blankly at the spread-out tattered roll. If she was not mistaken, this thing should be a sleeping bag?

She was still in a daze, but Mo Shougui had already started to check it out himself, and he soon discovered the strangeness of the quilt.

Yu Hongdou watched the teacher magically sliding the zipper back and forth, feeling a magical sense of being messy in the wind.

But soon her attention was no longer on the teacher and the zipper, because she saw a notebook.

The black leather notebook was supposed to have been wrapped in the fur of some animal, but it fell out because Mo Shougui shook off the sleeping bag.

Yu Hongdou bent down to pick it up, but ended up bumping into Tan Yanlin who was bending down at the same time.

"Ouch~" Yu Hongdou's head hit Tan Yanlin's chin, and both of them screamed in pain at the same time.

Yu Song and the guard, who were looking for a mechanism on the wall to see if there was any other way out, were so scared that they rushed over.

"Brother, I'm fine, I just got stabbed in the chin!" Yu Hongdou covered her head with her hands to comfort her brother who was checking her up and down.

"My name is Iron Head Hammer." There was a hint of frustration in Tan Yanlin's tone, proving that he was indeed in a lot of pain.

"..." Mo Shougui, who had already put down his sleeping bag and was ready to study the black notebook with his little apprentice, was speechless. What a childish couple.

It hurt, but she couldn't help but read the notebook. Yu Hongdou held the notebook and moved to the torch on the wall. She nudged Tan Yanlin, who was too close, with her shoulder and finally opened the notebook...
