Tang Li and Qi Yihan continued walking.

After walking for another ten minutes, Qi Yihan took out his phone again.

After looking at it, he told Tang Li where they were.

It was actually the most steep and complicated place in the Qinling Mountains.

“What tombs are there?”

Qi Yihan thought for a moment and told her, “As far as I know, there is no imperial tomb around here.”

If that was the case, this tomb was very likely to be one that was not recorded in history or had never been found.

Either way, the danger inside was obvious.

Tang Li held his hand tightly and said, “When we’re in danger, stand behind me.”

Qi Yihan tilted his head to look at her and smiled. “Don’t think of me as weak. As long as it’s not a demon, I can protect myself.”

Tang Li said seriously, “There won’t be demons or ghosts here, but there might be poisonous insects and zombies.”

These words made Qi Yihan’s expression turn serious.

“Don’t worry, Qiqi and Linlin can handle these things. They’re ancient divine beasts. As long as we don’t encounter ancient divine beasts of the same era in these tombs, zombies and insects will only become their food.”

Actually, she was worried. “There might be ancient divine beasts in this kind of ancient tomb. Qiqi and Linlin will be fine if they encounter ordinary ancient divine beasts, but they are afraid of combat beasts.”

Qi Yihan nodded.

The two of them continued walking.

This aisle seemed to be endless. No matter how long they walked, they could not reach the end.

However, the road became narrower and narrower.

The first aisle they walked was at least ten meters wide, but now it was only two to three meters wide.

From the light they emitted, they could see the stone wall around them. It was carved in the most primordial way.

“The wisdom of the ancient people is indeed not to be underestimated. They seemed to have carved their way through a gigantic rock.

“Yes,” Qi Yihan said. “In ancient times, imperial tombs usually started to be built from the time the emperor ascended the throne and finished after the emperor died.”

At this point, a red light suddenly appeared in front of them.

“It’s not Qiqi and Linlin.”

After saying that, a talisman appeared in Tang Li’s hand.

When the red light approached the light, they finally saw what it was.

It was actually a bug that looked like a beetle with red spots on its body. However, this bug was dozens of times larger than a beetle.

“This is a poisonous insect.”

After saying that, Tang Li threw the talisman at them. A ball of flames ignited in the middle of them and stopped them from approaching.

Tang Li and Qi Yihan stood there and looked at the bugs that were crackling and struggling.

Tang Li said, “This bug carries poison. Its large pincers can easily break through a person’s skin and inject the poison into their body.”

At that moment, a foul smell came from the burnt bugs. Tang Li threw out another talisman, which immediately blocked the smell.

Tang Li continued, “The food for this kind of bug is the corpses in the ancient tomb. After so many years, they have eaten up everything they had. They are now in an extremely hungry state. If a corpse appears, more of these bugs will swarm over from all directions.”

“Can these bugs only live on corpses?”

“No, if they only ate corpses, they would have starved to death long ago. Other than corpses, there is also a kind of plant here. This plant is food for various bugs in the tomb.”

“What plant?”

“Nether Grass.”

Qi Yihan was worried about Butler Yang and the others. “What if these bugs go straight to Butler Yang?”

“No, they won’t go out of the tombs.”

The two of them stood there for a long time, waiting for all the bugs to be burnt.

Tang Li threw another talisman over, and the ashes of the bugs blew away, leaving a clean path.

The two of them continued walking.

Qi Yihan received the data from the device as he walked.

After walking for some time, the two of them were hungry and stopped to eat.

Qiqi and Linlin came back at this moment. The moment Linlin came back, she hugged Qi Yihan’s thigh and asked for food. “Godfather, I want to eat too.”

Tang Li tugged at her braids and asked, “Haven’t you guys had enough food in the tomb?”

“I have, but it was not delicious.” After Qi Yihan gave her some of the food in his hand, Linlin let go of his thigh with a smile and stood in front of Tang Li with a smug expression. “Godmother, we’ve wandered around here and eaten a lot of zombies. There won’t be any zombies attacking us now.”

Tang Li nodded and praised, “Not bad.”

Then, she asked Qiqi, “Qiqi, do you want to eat something?”

Qiqi shook his head. “I want to save my stomach for the evil creatures inside later.”

He continued, “There are a lot of evil spirits and poisonous gas here. The deeper we go, the more complicated the terrain is. Linlin and I walked for a long time, but we didn’t find an exit. Instead, we found a very wide underground river.”

Linlin added, “The underground river is so deep, and the water is red.”

Tang Li and Qi Yihan looked at each other. Tang Li said, “Let’s go over and take a look first.”

Qi Yihan had no objections.

After filling their stomachs, the four of them continued walking forward. Just as Linlin had said, they did not encounter any zombies along the way. Even if they encountered all kinds of bugs, when Linlin passed by, these bugs immediately fled in fear.

The four of them walked for a while longer. The aisle became even narrower, and there was actually a light at a distance.

There were also carvings on the stone wall.

The carving was a map. The two of them studied it for a while but couldn’t tell which dynasty it was from.

After walking for a while more, they walked out of the tunnel. After walking out, the terrain inside started to become complicated. However, with Qi Yihan’s detector and Tang Li’s compass, they did not get lost and soon arrived at the underground river.

The underground river was at least a thousand meters deep. On both sides were vertical cliffs. There was something glowing on the cliff. Looking down from the side, one could indeed see red water flowing.

Tang Li asked Qi Yihan, “Yihan, can your detector go down? I want to see what’s flowing in this river.”

Qi Yihan took out his phone and quickly operated it. The detector ran over from the side and jumped down.

Tang Li craned her neck to look at the falling detector and was a little worried. “Will it break?”

“No.�

As soon as Qi Yihan finished speaking, a pair of wings suddenly extended from the detector and brought the liquid up.

After Qi Yihan got Tang Li to take out his tools, he started to analyze the liquid.

Tang Li also carefully observed the red liquid and sniffed it before saying, “It seems like blood, but the smell is very faint. Also, there’s a very strong evil spirit inside. If a person falls in, they probably won’t be able to come back up.”

Qi Yihan quickly got the result. “Yes, this liquid contains many things that can corrode the human body. Once a person falls in, they will immediately be corroded.”

After saying that, he took off the gloves. Only then did he realize that the gloves were actually corroded.

Tang Li was shocked. She quickly grabbed his hand and examined it carefully. “Do you feel uncomfortable?”

“I’m fine.” Qi Yihan touched her head with his other hand and said, “This glove is very heat-resistant and anti-corrosive.”

After saying that, he checked the detector and heaved a sigh of relief. “Luckily, this liquid can’t corrode the detector made of special materials.”

At this moment, Qiqi and Linlin suddenly called out to them.

“Godparents.”

Qiqi pointed at the other side of the river. “There’s someone on the other side of the river.”

Tang Li and Qi Yihan quickly turned around.

It was really a person and was someone Qi Yihan knew. “It’s actually one of the people who went down to the Xuanyuan Tomb this time.”

There were only three or four people on the other side. Although they were nearly twenty meters away, it was obvious that they were in a sorry state. There was fear on their faces. At this moment, they saw Qi Yihan and were waving at him. At the same time, a person cried for help. “Fourth Master, Fourth Madam, is that you? Please save us. We’re being chased by a group of terrifying man-eating bugs.”

After that person finished speaking, another scream was suddenly heard. “Ah… Those bugs are catching up.”

As they spoke, a dense swarm of bugs appeared.

Those bugs were very fast. They were so terrified that they started climbing down the cliff.

When the bugs reached the cliff, they stopped.

The few of them heaved a sigh of relief and quickly descended the cliff.

Qi Yihan wrapped his arm around Tang Li’s shoulder, his expression cold. “We can’t save these people. They’re here to look for the Xuanyuan Tomb. Since they’re here, it’s very likely that this is the Xuanyuan Tomb. Since they don’t listen to our advice, they have to pay the price.”

Tang Li did not plan to save these people either. “They were cursed. They must have entered the main tomb and touched something they shouldn’t have.”

As soon as she finished speaking, that group of people descended to the bottom of the cliff.

They obviously thought that Tang Li and the others would come. Even if they were blocked by the red river, they did not stop and prepared to cross it.

However, as soon as these people entered the river, their bodies were instantly corroded, leaving only skeletons.

The bones quickly floated away with the red liquid.
