"Let's go out then. We need to find other secret rooms quickly." Yan An led Yue Xiyuan and the other two out of the space.

The four continued walking south, without noticing anything unusual along the way. Suddenly, Qi Hongchen stopped. "Xiyuan, it seems like there are no birds chirping around here."

A strange, pungent fragrance filled the air, tinged with an eerie red hue and extremely offensive. "Oh no, it's poisonous."

Yan An quickly took out three antidote pills and gave them to each of them. He also took out four gas masks. Luckily, Yan An had kept these as a backup when he was in the modern world and had brought them back with him.

Once, when Yan An was conducting an experiment, the drug he was developing suddenly emitted puffs of smoke, which Yan An found quite alarming. From then on, Yan An prepared several gas masks in case he was "poisoned" during his next experiment.

Yue Xiyuan and the others followed Yan An's example and put on their gas masks. "An'an, this thing can actually block the poison gas?"

After Wol Seok-won put on the gas mask, the invisible hands binding his neck seemed to disappear.

"It's not always effective. I've improved this gas mask so it lasts about an hour. So we need to hurry. Based on the formation we just saw, there's probably a hidden door here too."

“Let’s split up and search,” Yue Xiyuan said to Qi Hongchen and the other man.

The toxic gas in the air grew thicker and thicker, making it impossible to see clearly. Su Jingzhan kept groping around, and a huge object stood in front of him. "Xiyuan, come and see, there is a hundred-year-old tree here."

"That old guy is really ruthless and vicious. He actually planted the Heavenly Desire Dream here. Even if you only smell a trace of it, you will be poisoned. If it weren't for our junior sister giving us the antidote pill in time, we would either be screaming like dogs or in a state of dizziness, losing our minds, falling into illusions, and eventually dying."

Su Jingzhan felt very familiar with this poison from the beginning. He suddenly remembered that this poison was the Heavenly Desire Dream that his master had told him about. He never expected that it would be used here.

"This tree looks to be several hundred years old." Yan An touched the trunk; even a small branch was stronger than Yan An himself.

"Xiyuan, come quick! There's a hole here." Qi Hongchen circled the towering tree and found a hole about three meters above the ground. It was so small that you wouldn't notice it unless you looked up and looked closely.

"I'll go up and take a look first. An'an, wait for me down here." Yue Xiyuan took the lead and flew up.

"So? What's up there?" Yan An asked.

“There’s a downward passage inside the trunk of the towering tree. I’ll go down and take a look.” Yue Xiyuan jumped down.

“I’m going too.” Yan An followed closely behind, followed by Su Jingzhan and Qi Hongchen.

"It's quite spacious inside. I didn't expect there to be a ladder." Su Jingzhan went down the ladder from the entrance.

"I never imagined that this towering tree could still survive after being dug so deep." After landing, Yan An took out a palm-sized luminous pearl from his spatial storage, instantly illuminating the cave.

"Ah! Xiyuan actually gave you this luminous pearl. He really values ​​women over friends."

Su Jingzhan was a little jealous. He had asked Yue Xiyuan for this bead for a long time but had never given it to him. Now it was in Yan An's hands. It was a waste that he had known him for so many years and that Yan An did not care about the order of arrival.

If we have to decide who came first, then Yue Xiyuan was promised to Yan An as his wife when he was six years old, so it's hard to say who came first.

Yue Xiyuan touched the stone door. "Just like the previous one, it's double-layered. Let's go out first."

After the four emerged from the tree hollow, they remarked, "It seems that each hidden door is guarded by a formation, and there must be more than one or two such hidden doors."

"Hongchen, can this be drawn?" Su Jingzhan looked at the towering tree and the hole in the tree.

“This place is full of poisonous fog. I’ve tried to draw the approximate location, but it’s definitely not as detailed as the location of the first hidden door.” Qi Hongchen frowned. With such low visibility, it wouldn’t be easy to draw it accurately.

"Please bring out the brush, ink, paper, and inkstone, Your Highness. I need to paint outside."

“Okay.” Yan An’s consciousness flashed and he took out the brush, ink, paper and inkstone, and even a table and chair.

Thank you.

The three of them, including Yue Xiyuan, sat down to the side and stopped bothering him.

Just as Yan An was about to take out a few more gas masks, which were about to expire, she heard Qi Hongchen say, "Okay."

Yue Xiyuan picked up a few sheets of paper from the table. The second secret door was located directly south of the first secret door, about fifteen or sixteen miles away. "Good, let's hurry up and leave."

"The exit is this way." Yan An pointed southeast, and the four of them walked in that direction.

"Finally out! I was so suffocated!" Su Jingzhan took off his gas mask and gasped for breath.

Yan An casually tossed four gas masks into the trash can in his spatial storage, where they vanished instantly. He then brought out four bowls of water from Tianshan Mountain. "Have some water and rest a bit."

"Thank you, Your Highness."

"Thank you, junior sister."

How can it be that Su Jingzhan was the one being threatened? Look at Qi Hongchen, he keeps calling her "Princess," a term that resonates deeply with Yue Xiyuan. And Su Jingzhan? He keeps calling her "Junior Sister." Yan An is a junior sister, but what is Yue Xiyuan? He's practically her brother-in-law! He's clearly taking advantage of Yue Xiyuan…

Yue Xiyuan gently rubbed Yan An's small hand, never letting go of her hand except when scouting the way. Suddenly, he whispered in Yan An's ear, "Thank you, An An." Even Su Jingzhan was being so sweet, so naturally he couldn't fall behind.

Su Jingzhan and Qi Hongchen squinted at the two's actions: "I can't bear to look, I can't bear to look... There are just too many bastards along the way." They immediately turned away.

Seeing that the two were so sensible, Yue Xiyuan smiled slightly and gently touched Yan An's lips, saying, "The water is sweet, but you are even sweeter."

Su Jingzhan and his companion got goosebumps from listening, but dared not make any move. They could only hold their cups tightly with both hands and stand with their backs to them.

"Let's go, there should be quite a few more. Each hidden door should have a formation, everyone be careful." Yan An put away the cup, and Yue Xiyuan led Yan An around the two of them and walked ahead.

The four walked for a long time, and even Yan An was a little tired. "Why aren't we here yet? There shouldn't be only these two."

"Jingzhan, be careful." A sword shadow rushed towards Su Jingzhan from the side. Su Jingzhan dodged the attack after being reminded by Yue Xiyuan.

Perhaps because the other four shadows had not killed Su Jingzhan, they all flashed out, dressed in white, like ghosts, their faces obscured, and all stabbed at Yue Xiyuan and the other three. Yue Xiyuan frowned slightly, drew his long sword from his waist, and went to meet them.

Yan An and the other two each fought one, while Yue Xiyuan fought two by himself. The four against five were evenly matched, and Yue Xiyuan and his group became more and more courageous as they fought, while the Five Ghosts also rose up to catch up.
