"Let's have a picnic here at noon, okay?"

"Okay!" The three of them said in unison. The clear and crisp voices echoed in the valley, attracting a flock of flying birds.

"You guys just play here, don't run too far, and don't get too close to the water. Mother will prepare lunch."

The three of them agreed and immediately ran away in a swarm, frolicking wildly on the grass.

Shen Yizhi couldn't help but smile as he looked at it, and took out ingredients one by one from the space.

"Ah!" A scream came from not far away.

Shen Yizhi immediately put down the fish in his hand and ran over, "What's wrong, Nian Nian?"

"It suddenly became so hot." Nian Nian took out the fang from around her neck.

Shen Yizi touched it and found it was true.

"Take it off first." She untied the tusk.

Unexpectedly, the moment it left Nian Nian's neck, the long fang actually floated up by itself, with the tip of the fang pointing directly at... the lake.

As if receiving some kind of call.

Shen Yizhi looked at the still confused Nian Nian and wondered if this growing tooth had touched upon some important plot point?

Is it an opportunity or a trap?

"I'll keep it for you first. After we finish our meal, we'll go check it out."

Shen Yizhi put the fang into the space. Once it entered the space, it calmed down and showed no abnormalities.

While eating, Shen Yizhi asked Yichang to go to the lake to explore.

"How about it?"

Yichang shook off the water on his tail and said, "There's nothing special down there, but there's a dark mountain. I feel like there's something wrong with it."

"Mountain……"

After dinner, Shen Yizhi sent Qingbao and Yuanbao into the space, but left Niannian outside.

Changya was left by her mother. Its movement just now must be related to her. It would be better to take her with you. Maybe she is the key to unlocking the plot.

If she encounters danger, it will not be too late to send her into the space.

"Let's go down and explore."

Shen Yizhi picked up Nian Nian, took out the long tooth, hung the water-slip beads that Old Feng had given her when they were in Prince Chen's Mansion around her waist, and went into the water.

The effect of the water-walking beads was indeed magical. After she entered the water, her breathing was completely unimpeded, as if she was walking on the ground. The same was true for Nian Nian, who was in her arms.

Following Changya's direction, Shen Yizi dived all the way down. The deeper they went, the darker the lake water became. Fish passed by them from time to time. Water plants swayed, and it was quiet all around except for the occasional sound of water stirred up by a big fish swimming by.

This is an underwater world that is completely different from the one on land.

Nian Nian's eyes were full of curiosity. From time to time, she reached out her hand to tease the passing fish. Seeing the fish running away in panic, she couldn't help laughing, her laughter as loud as a bell.

Finally, Shen Yizhi followed Changya's instructions and came to a dark mountain that looked like a crawling giant beast.

"Is this the mountain you mentioned earlier?"

Yichang: “That’s right.”

The long fang in Shen Yizi's hand suddenly flew out and crashed straight into the mountain wall.

She was startled, but reacted quickly and grabbed the red rope that was inserted into the tusk.

However, the impact of the fangs was so great that she failed to catch them and was knocked against the cliff.

At the moment of impact, she turned her body to the side, relieving most of the force.

However, something unexpected happened. The moment the fang touched the mountain wall, ripples appeared on the mountain wall like the surface of water, and the fang rushed in.

Shen Yizhi and Nian Nian also fell in.

When I looked up, the surrounding scenery had completely changed.

In front of her was a palace with a plaque reading: Fengqi Palace. The closed bronze door exuded an ancient atmosphere. She was standing at the steps in front of the palace.

There is a void behind me.

There is no water or fish around, and the mountain is nowhere to be seen. It seems like another world here.

They must have passed through a barrier just now, right?

The long tusk in her hand had calmed down and was hanging quietly on the red string.

Nian Nian looked around curiously: "Aunt Shen, where is this?"

Shen Yizhi shook his head: "I don't know either."

Yichang said: "It should be an independent small space. This fang is the key to enter this space."

Shen Yizhi held Nian Nian in his arms and stepped onto the stairs. There was a lock hanging on the bronze door, and the keyhole was shaped like a small hole.

"Could the key to this door also be this tusk?"

Shen Yizhi decided to give it a try, and after thinking about it, she decided to let Nian Nian do it. She was the owner of Changya, and she should be the one to open the door.

Nian Nian was held by her while she inserted the long tooth into the keyhole and twisted it downwards. With a "click", the lock opened.

When Nian Nian withdrew her hand, a thin needle suddenly emerged from the keyhole and pricked her.

A drop of blood suddenly appeared in the palm of her hand.

Shen Yizhi was horrified, holding Nian Nian and quickly retreating, holding her hand and checking it carefully, "Nian Nian, are you okay?"

Nian Nian shook her head.

It was just a stab, and the pain was nothing to her.

Shen Yizi was still worried, so he wandered around her body with his spiritual sense, but indeed found nothing unusual.

"Could it be that the needle was just to prick Nian Nian?"

Yichang thought of a possibility: "Perhaps it was to test the bloodline of the person who opened the lock. This place might have been left by Nian Nian's ancestors. If the person who opened the lock was not Nian Nian, then he might have met with an accident by now."

Just then, the door opened.

It seemed as if he was responding to Yichang's words.

It seems he guessed right.

Shen Yizhi put the long tooth back on Nian Nian's neck, and tried to probe into the hall with his spiritual sense, but was blocked by a force. There must be a formation set up in the hall that did not allow spiritual sense to detect.

Yichang volunteered: "I'll go and take a look."

However, Yichang did not send any message back after he went in, as if he had disappeared.

What is the situation in this hall? Never mind, let's go in and take a look. Now the way back is gone. If we want to get out, we can only go into the hall and look for the exit.

Shen Yizhi held Nian Nian's hand and slowly walked into the hall.

The moment she entered, she was almost blinded by the light.

The hall was spacious, yet magnificent. Under her feet was a small piece of Xuan jade worth a thousand gold pieces. The colors were gorgeous, and she felt like she was standing on a mountain of gold and silver.

The thick stone pillars of the bathtub are made of rose stone and are carved with various strange beasts in strange shapes.

There is the Yayu (pronounced the same as Yayu) with a dragon head and a tiger body. It is said that this is a man-eating beast. There is the Yanwei with a human head and a snake body. This is a main deity for worship. It is said that worshipping this god can dominate the world. There is the auspicious beast Bai Ze with a sheep horn and a lion body, a white body and a mouth that can speak human language...

There are ninety-nine of these thick, tall, and brightly colored pillars in the hall. Supported by these giant pillars, the entire hall looks vast and spacious, like a temple from ancient times.

On the top of his head, there are fist-sized luminous pearls inlaid, like stars in the sky, illuminating the entire hall.

On the stone walls on both sides, there are murals with bright lines and unrestrained style.
