Gu Jueye ignored Feng Yi and looked indifferently at the gloomy face.

At this moment, his gloomy gaze became even colder as he stared unblinkingly at the two people's tightly clasped hands.

"It seems you two have a good relationship, but I wonder what the man beside you will choose when faced with life and death."

As Yin Chi finished speaking, the hand that had been resting on the table gently tapped three times.

In the blink of an eye, eight doors suddenly appeared on all four sides of the room, each door being almost identical.

Bai Qianmo's expression subtly changed.

At that moment, she noticed that the house was not square, but rather a polygon that was close to a circle.

Because the room lacked modern lighting, no one noticed the other seven hidden doors, except for the single exit that led to the outside.

"Damn, Feng Yi is really cunning. This is a Taoist Bagua Transformation Formation. Be careful."

Almost as soon as Feng Yi finished speaking, a sound of a mechanism being activated came from inside the room.

Immediately afterwards, the entire room began to shake violently as if an earthquake had struck.

Bai Qianmo narrowed her eyes and looked in the direction of Yin Chi.

Then they saw Yin Chen and Liu Fuyong walking towards a door.

As soon as they ran inside, the door began to slowly close.

Bai Qianmo said to Gu Jueye and Feng Yi beside her, "Follow him."

Gu Jueye and Feng Yi had the same idea, and the three of them quickly ran towards the door.

The three people had just run in when the stone door slammed shut.

But after entering the door, Yin Chi and Liu Fuyong were nowhere to be seen.

Looking around, there was an extremely narrow passage.

"What is the Eight Trigrams Transformation Array?" Gu Jueye glanced at the long passage ahead with his cold gaze and asked Feng Yi beside him.

"It's the Mohist school's mechanical arts. It roughly means that a mechanism is set up in a house, with a hidden door in each of the eight directions. When the owner of the room touches the mechanism, everyone will open up in an instant. These eight doors are derived from the numbers of Qimen Dunjia, corresponding to the eight gates of Rest, Life, Injury, Block, View, Death, Shock, and Open. If you encounter a master, these eight doors can be changed at any time."

Bai Qianmo was silent for a moment, then raised her question: "Does that mean the Gate of Life could also turn into the Gate of Death?"

Feng Yi nodded: "I didn't expect Yin Chi to be so proficient in the Mo family's mechanical arts. He's more difficult to deal with than we imagined."

"What I'm more curious about is, what is the relationship between Yin Chi and the Mo family? The Mo family's mechanical arts are all passed down through direct lineage. If you're not a direct descendant of the Mo family, you would never have the opportunity to come into contact with these things."

Feng Yi looked at Bai Qianmo: "You are right. Only the direct line of the Mo family is qualified to access the Mo family's mechanical arts. However, few people know that Yin Chi is not only a member of the Yin family, but also a direct line of the Mo family."

A hint of surprise appeared in Bai Qianmo's calm eyes.

Feng Yi continued, "Yin Chi's father is Yin Huai, the head of the Yin family. However, Yin Chi's mother is not the matriarch of the Yin family. Instead, she is the illegitimate son of Yin Huai and a daughter of the Mo family. That's why Yin Chi rarely appears in the Yin family. In the Mo family, because Yin Chi's birth is a shameful matter, the Mo family has never recognized Yin Chi's identity. So I guess that his proficiency in the Mo family's mechanical arts is related to his mother."

Gu Jueye, who had been silent all along, slowly spoke: "Right now, our most important task is to find a way out."

Feng Yi shrugged, looking indifferent: "There's no turning back for us, let's keep moving forward."

Watching Feng Yi stride forward, Gu Jueye tightly grasped Bai Qianmo's hand.

"You must stay close to me."

"Okay!" Bai Qianmo nodded obediently.

The passageway is very narrow, only wide enough for one person to walk through.

Feng Yi led the way, while Gu Jueye, worried about Bai Qianmo, let her walk in the middle, and he chose to bring up the rear.

The three of them walked along like this. Bai Qianmo roughly calculated in her mind that they had walked for at least half an hour, but the passage had not yet come to an end.

"If I'm not mistaken, this guy is a giant rat that comes to the deep mountains and forests to dig all sorts of caves," Feng Yi sneered, mocking Yin Chi.

Bai Qianmo held up her phone's flashlight, which was their only source of light at the moment.

She wasn't in the mood for teasing at the moment, and kept glancing back at Gu Jueye, afraid that he hadn't kept up.

Gu Jueye seemed to have seen through her thoughts, and kept a distance of less than half a meter from her, so that Bai Qianmo could hear his steady footsteps at all times.

The three of them continued walking along the passage for another half hour, and finally a door appeared in front of them.

"Be careful, there might be traps," Bai Qianmo warned Feng Yi.

Feng Yi nodded and walked over first. He stood in front of the door and studied it carefully for a moment, then raised his arm and pushed hard, and the stone door slowly began to turn.

"It's a revolving door, a type of door often used in tomb chambers and mechanism rooms. There must be other mechanisms here as well."

Bai Qianmo held up her phone and looked inside, but it was pitch black, and she couldn't see what was going on.

"I'll go in first, and once I'm sure everything's alright, you can come in." After making the decision, Feng Yi lifted his foot to step inside, but Gu Jueye grabbed him.

"Don't go in yet, something seems off here."

"Something's not right?" Feng Yi looked at him in confusion.

“This is a revolving door. As you just said, this kind of door only appears frequently in tomb passages and mechanism rooms. Since it is here, it means there must be something inside.”
