I didn't expect that I was the heartthrob.

After hearing this, Gu Lan's heart beat faster and he hurried forward.

Before she had taken a few steps, she suddenly felt a chill from behind and a sharp sword flew towards her heart.

Fortunately, Gu Lan reacted quickly and dodged by rolling sideways.

It was really disadvantageous in this darkness. I was originally afraid that light would bring danger, but now that I was in danger, I didn't care about that.

Gu Lan quickly formed seals with his fingers.

I saw her muttering something, clasping her hands tightly, and turning her fingers continuously between several breaths. While doing this, she took a deep breath and retreated backwards. As she retreated, she flew up into the wind, like a piece of silk cloth, floating away.

After the seal was completed, Gu Lan called out: Sun, moon, stars, all things are light, shine!

I saw that the place that was originally dark suddenly became bright.

With lighting, everything can be seen clearly. It turns out that this is a tunnel, about two people tall and six people wide. There are long paintings painted on the wall with colored minerals. Every few meters, there is a peculiarly shaped wall lamp.

After getting used to the bright light, Gu Lan looked at the attacker, only to find that it was Ling Yebai.

Ling Yebai had already put away his sword at this time.

"What do you mean?" Despite the obvious difference between the two, Gu Lan questioned Ling Yebai without a good look on his face, "You should know that the person in front is either me or a disciple from another sect. It's inappropriate for you to kill him like this."

Ling Yebai did not intend to hurt Gu Lan. After he came in, he was in darkness and did not know what to do. Suddenly Lingyao appeared beside him, so he walked forward with her. However, Lingyao turned into a monster and attacked him halfway.

With this experience, Ling Yebai naturally became more cautious and wanted to use the magic sword to clear the way. Just now, he heard a sound in front of him, and thought that another monster had appeared, so he threw the magic sword in his hand over, trying to strike first, but he almost hurt Gu Lan.

Ling Yebai was a proud person by nature, so he was unwilling to elaborate on the reason and just bowed his hands to apologize.

Gu Lan pursed her lips, her teeth itching with anger, "I don't accept your apology."

Ling Yebai thought about it and it made sense. He had intended to kill someone with that sword. If Gu Lan hadn't reacted quickly, it would have been broken into two pieces. A light apology seemed inappropriate.

"Then I owe you a sword. If you are in danger, I will definitely block the sword for you."

"Are you serious?" Gu Lan became interested, his eyes lit up.

"My words are of course trustworthy." Ling Yebai didn't want to say more. He turned his head to look at the mural and saw a wall lamp. He flicked his hand into the wind and the wall lamp was lit.

In order to conserve his spiritual energy, Gu Lan raised his right hand to summon a butterfly and withdrew the magic he had just performed.

In an instant, the tunnel became much darker. Seeing this, Ling Yebai counted and lit up all the wall lamps on both sides.

At this time, the tunnel was brightly lit.

After doing all this, the two of them looked at the mural carefully.

The mural depicts the rise and fall of this demon clan.

The demons living here are the earth demons.

There are three types of demons: heavenly demons, earthly demons, and human demons.

The Sky Demon Clan is the essence of heaven and earth, nurtured by heaven, and is born with extremely high spiritual roots. However, since it is not easy for heaven and earth to nurture, only one or two can be born in a thousand years.

The Earth Demon Clan is a creature conceived by the earth, a condensation of the earth's energy.

This type of demons often have many races, different appearances, and varying intelligence. Only a very small number of demons can form an ancestral lineage and reproduce from generation to generation. Most of the time, there is an extremely powerful demon that conquers other demons, and eventually proclaims himself the Demon Lord and leads an area.

There is another type, namely, human demons. This type is the demon race formed by cultivators who have been possessed by demons. Although they are called demons, they are not recognized by the demon race, so they become the only alien species in the world and are ostracized by both sides.

This is a tribe of earth demons. They are very similar to humans, with only one difference: they have wings on their backs.

At first, the tribe lived here for generations and did not harass the surrounding residents. Over time, the two even traded with each other and lived in harmony with each other. But one day, the demons discovered a spirit stone mine, which enabled them to practice even faster. They were discovered by a nearby sect, which coveted their spirit stones and negotiated with all parties to take some of them.

However, the two sides could not reach an agreement and a dispute arose, so that sect persuaded other sects to seize the land. A great war broke out, and the place was turned into a ruin. The demons and that sect were all destroyed.

After seeing the end, Ling Yebai snorted coldly.

The Xuantian Sword Sect has records of this incident, but according to the records within the sect, the facts were completely the opposite. A spiritual mine was discovered within the sect, which was coveted by the demons. In the end, the two sides fought and severely injured each other.

"What's wrong?" Gu Lan asked when she saw him sneer.

"These are all fabricated nonsense!" Ling Yebai waved his sleeves and was about to destroy the mural, but Gu Lan hurried forward to stop him.

These are all cultural relics!

"Even if it's fabricated, you can't destroy it. It won't cause any trouble if you keep it. Besides, in my opinion, it may not be true even if you know it. History is written by the victors. They can write whatever they want. The losers can't come back to life and speak out. If I were you, I would never listen blindly and believe it."

Ling Yebai had never heard such remarks before, and in his opinion, what Gu Lan said was very unorthodox.

If you doubt even the things recorded by your master, wouldn't that be a betrayal and an insult to your master? But after careful consideration, what Gu Lan said was not without reason.

"But who painted this mural? Since all the demons are dead, there should be no one who can paint it. Besides, the victorious party can't paint such a mural, right?" Gu Lan touched his chin, "Do you think..."
