After my soul traveled through time and space, I became the male protagonist Bai Yueguang

Ji Zhengxuan was in charge of looking after Duan Luchong and Mu Daiying. After receiving Situ Rui's instructions, he began to question them.

He had never thought that Duan Lu Chong was actually a romantic man, and the one he loved was the eldest daughter who had long been abandoned by the Mu family.

Duan Lu Chong had already become disheartened. Seeing that his plan had failed and being threatened by Ji Zhengxuan with Mu Daying, he no longer cared about the so-called secrets of the Cai family. Under Mu Daying's disapproving gaze, he forced himself to reveal the location of the underground passage.

The underground passage was not in the Cai family's house, so even if Mu Yanchen and the others turned the Cai family's old house upside down, they would not be able to find it.

"It's here." Situ Rui held the lighting and pointed it at a small land temple next to a hundreds-year-old tree.

The land temple is in ruins, and the image of the land god has been blurred by the passage of time, leaving only a mound with some lines.

Even if I pass by, I won't pay attention to such a place.

Shen Zhao lamented the changes over the generations of the Cai family. They were indeed a clan that had been passed down from ancient times. Even though they were torn apart by modern rules, the clan's treasures could still be quietly preserved to this day.

With Mu Yanchen's consent, Situ Rui followed Duan Luchong's instructions and aimed the light at an inconspicuous hole in the land temple.

The light passes through the hole and then refracts onto the ground at a strange angle in the land temple.

There, under the moonlight, an inconspicuous bright line appeared.

The ground began to shake, and several people felt like it was the precursor to an earthquake.

"Are you okay? The Cai family is indeed hiding something!" Situ Rui said while maintaining his balance and turning his head to look at Mu Yanchen.

Mu Yanchen held Shen Zhao's hand tightly at the moment of the earthquake. Shen Zhao lowered his eyes to look at their clasped hands, then looked up at him, only to see his calm profile and the strong and smooth jawline.

She squeezed his hand gently, "It's just a mechanism, it's okay, don't be so nervous."

As soon as he finished speaking, his hand was tightened again. He whispered frankly, no longer hiding anything, "I have already lost you once, I can't take any risks. Only when you are by my side can I feel at ease."

Shen Zhao met his blazing eyes. In his dark pupils was an affection so deep that it made her heart tremble. It was strong and vast, like the unfathomable sea. She might never be able to reach such depth and breadth.

She looked at him for a long time, then shook his hand.

The terrifying shaking continued. Several people took a few steps back and watched from afar as the bright crack began to expand. The stones moved to both sides, and much of the grass growing on the stones fell into the huge crack.

The heart-wrenching vibration did not stop until the gap expanded to allow one person to pass through.

Situ Rui picked up the lighting and stood in front of the entrance to the underground passage. He swallowed and turned to look at Mu Yanchen, "Are you really going in?"

Shen Zhao was not afraid at all. She looked at Mu Yanchen, and he was looking back at her, as if they were separated by a time and space. She had already died once, and he was about to die. What was there to be afraid of? Even if they died, they were by each other's side this time, and there was nothing to regret.

She looked at Situ Rui. If he really died in the Cai family's underground passage, he might be the one who suffered the most injustice...

"Come in." Mu Yanchen said.

Situ Rui did not refuse. He walked in front and illuminated the way for his boss.

The passage was very narrow and only one person could walk behind another. Mu Yanchen asked Shen Zhao to walk in the middle and he did not allow her to walk out of his sight.

However, Shen Zhao discovered that the underground passage was dry and dust-free, and the cool night breeze could be blown in. This passage could indeed lead to the outside world. If there was a dead end inside, this underground passage would not be the case.

The few of them kept walking for about a thousand meters before they came to a place with a slightly larger area.

It was circular in shape, surrounded by stone steps, with an altar in the middle and a dome on top, supported by three round stone pillars. Shen Zhao took out his lighting and shone it around, and found that there were words engraved on the stone pillars, and on the stone round dome there were murals with some color fading, which looked like they were quite old.

The stone pillars are engraved with the Cai family's family rules, while the murals on the dome are vaguely speculated to be a story, about how the ancestors of the Cai family walked from a desolate sandy land to this fertile plain to live and multiply. At the end of the mural, there is a man in a grass skirt with his right hand raised, and in his hand there is a plant, which is all white in the mural, with golden light painted around it.

Shen Zhao could see how much the Cai family valued the plant, giving it a god-like status.

That should be what they call fireflies.

"Let's go forward, maybe we're almost there." Shen Zhao suggested that this should be the place where they arrange their strategies. The place is not big, but it is definitely enough to accommodate some important people in the family.

They kept walking, and after walking for about a kilometer, steps suddenly appeared in the underground passage. They went up one step at a time until they stopped in front of a stone gate engraved with the Cai family's ancestral precepts.

"How do I open this door?" Situ Rui asked.

Mu Yanchen stepped forward and put the light into a hole on the side. In a strange way, the light was transmitted to each word on the stone door. The stone door immediately emitted a white fluorescence, bright and holy.

Boom boom, like thunder, the stone door opened.

Warm yellow light shone through from inside, and simple bricks and tiles and maroon wooden pillars came into view. The temple was spotlessly clean and the space was not very large. On the altar facing the stone gate was placed the tablet of the ancestor of the Cai family, and on a carved stone table in the middle were three transparent bottles.

The three of them gathered around it. They couldn't tell what the bottle was made of, but it felt cold to the touch and looked translucent. It was filled with powder, as white as the plants in the mural.

"This should be the powder of firefly flowers, right?" Shen Zhao carefully picked up the bottle on the stone table and sifted it gently, making a crisp sound of powder hitting the bottle.

Situ Rui quickly put the three bottles of powder into the box and stood aside waiting for Mu Yanchen's instructions.

Shen Zhao didn't come here for Firefly Flower. Of course, it was also very important to bring Firefly Flower back. Even if she couldn't find a medicine to counteract it, as long as she had this original substance, she would not be afraid of not being able to find an antidote.

But time is running out, and she wants to find a substance that can counteract the fireflies.

She searched carefully around the entire temple, but there was no place in the temple where plants could grow. She heard that fireflies rely on blood for nourishment, so could the key lie in the Cai family's bloodline?

"How is it, any clues?" Situ Rui looked at Shen Zhao nervously.

Shen Zhao shook her head dejectedly. Every minute and every second tonight was especially important, but she did not give up. The incompatible things in the world are not necessarily plant to plant, it may also be other things. The growth of fireflies is special, and perhaps the secret lies here.
