The five ghosts, wielding their long swords, struck the four men with a powerful blow, as if gathering all the internal energy they had used in the previous fight, forcefully sending Yue Xiyuan and the other three flying several meters away.

The five ghosts gripped their swords tightly, gathering their inner strength into the blades, and emitted a mournful, ghostly howl. "Cover your ears, calm your mind, and don't listen."

Seeing that their demonic chants were no longer effective, the Five Ghosts leaped into the air again, brandishing their swords and charging down to strike the vital points of Yue Xiyuan and the other three.

"Sever their arms and cut off their two longswords." Yue Xiyuan leaped lightly, soaring into the air and passing through the jungle. He circled in the air, then swung back down, immediately severing the two demons' two longswords.

At the same time, Yan An and the other two also severed the ghost's arm, and the five ghosts vanished instantly.

"Xiyuan, what was that thing just now? Why did it get fiercer as we fought?" Su Jingzhan was terrified at the thought that if the fight continued like that, they would be exhausted.

"It's the Five Ghosts Yin Wind Sword Formation. Those five ghostly figures were the Five Ghosts. When they draw their swords, they channel their inner force into the blades, using the small holes in the blades to vibrate the air and produce a wailing sound, thus disturbing our minds and killing us. Even if their demonic sounds have no effect, they will wear us down. The deeper our inner force, the stronger they become, and they never run out of energy."

"This Ji Yuan is truly ruthless and vicious. The reason he built this secret room is definitely not as simple as a secret rendezvous."

Su Jingzhan said resentfully, "That old guy is really persistent. He's been dead for so many years, but he still keeps these things around."

With a bang, a mechanism on the ground was activated, revealing a hole in the ground.

"It seems that breaking this Five Ghosts Yin Wind Sword Formation will open the entrance. If nothing unexpected happens, it should be the same as the previous two. You wait here, I and An'an will be right back."

"This place is much more spacious than the previous two entrances," Yue Xiyuan said. He led An'an inside for about several dozen meters and they saw a stone gate that looked exactly the same as before.

"Just as I suspected. Let's go out and not keep them waiting."

Qi Hongchen and his companion brought Yue Xiyuan and Yan An out. "How was it?"

“It’s exactly the same. It’s easier to draw here. Let’s go get something to eat and then continue on our way.”

He must be exhausted from the journey, not to mention the fight he had. His An'an must be starving.

Yan An's consciousness flashed, and the four of them arrived in the space. Yue Xiyuan told Yan An to sit and wait, as he had just learned how to make instant noodles. Yue Xiyuan then called Su Jingzhan to prepare the meal.

The noodles were almost ready, and Qi Hongchen had finished his painting. After the four of them ate, Yue Xiyuan and Su Jingzhan cleaned up the trash, while Yan An looked at the painting repeatedly.

"Yue Xiyuan, look at this compiled map. Aren't the locations of these three secret doors a bit too obvious?"

Qi Hongchen not only drew the location of the secret door, but also calculated the approximate distance based on the direction and number of steps they took, and drew a summary map.

Yue Xiyuan took the map, looked at it, and it was indeed so. The first secret door was due north, the second was due south, and the third was in the southeast. Although some were closer and some were farther away, they were all in the correct directions.

"Indeed, as An'an said, if that's the case, there are likely eight such secret doors in other locations as well."

“These aren’t on the same route, it might be difficult.” Su Jingzhan threw the instant noodle box into the trash can and looked over.

"The road to the due east is an official road, heavily guarded. It shouldn't be too close to the cliff edge. It's getting late. If we find this hidden door to the due east, we'll rest for the night and look for the others tomorrow."

Yan An's consciousness flashed, and the four of them left the space again.

"Let's split up. We're not far from the edge of the cliff now. I'll go west with An'an, and you two go east."

It's getting late, and who knows how many more formations are still hidden on this mountain? If we're not careful and get trapped inside, we might never be able to get out.

"Senior brother, take this whistle. If you don't find it, sound it twice; if there's danger, sound it once; if you find the secret door, sound it three times. Little Grey will come looking for you. Remember, you must not act on your own."

Yan An took out a whistle exactly the same as the one given to Yue Xiyuan and handed it to Su Jingzhan, so that if they got lost here, they could rely on Xiao Hui to find them.

Yue Xiyuan roared inwardly, "Waaah, the things my wife gave me, I also gave to Su Jingzhan. It's okay, An'an gave them to him first. An'an still cares about him more." After a period of self-pity, Yue Xiyuan accepted reality.

Su Jingzhan and Qi Hongchen searched eastward and soon arrived at the edge of the eastern cliff. Just as Yue Xiyuan had predicted, they found nothing.

Su Jingzhan blew two whistles and, together with Qi Hongchen, headed west.

"It's Senior Brother. They haven't found him yet, so they're probably on their way here." Yan An released Little Grey from his spatial storage. "Little Grey, go and bring Senior Brother here."

Little Gray flew eastward and disappeared in an instant.

"Let's keep going." Yue Xiyuan held Yan An's little hand and continued walking forward. The calluses on Yue Xiyuan's hands, which he had developed from practicing martial arts since childhood, were rubbing Yan An's hands as if giving her a massage, which felt ticklish and comfortable.

"An'an, we've arrived."

A cave five meters wide stood before them. Yue Xiyuan looked around but saw no array formations. “Something’s not right here. An’an, be careful.”

Yue Xiyuan picked up several fallen leaves from the ground, concentrated his inner strength into them, and instantly released them towards the cave entrance. Just as the fallen leaves approached the cave entrance, they were completely corroded away.

"It's the Cave of a Hundred Poisons!"

Yan Anchaoyue Xiyuan explained, "The Hundred Poison Cave, as the name suggests, is made with a hundred kinds of poisons. The toxicity will vary depending on the poison used. Some will cause mental breakdown and become a walking corpse, while others will instantly turn into a skeleton. It is rare to find a Hundred Poison Cave that can instantly corrode things. However, the mixed poisons will have great differences in toxicity and smell, so most of them are colored and extremely smelly. There are really not many that can make the poisons colorless and odorless. But judging from the formations just now, it seems like something that Ji Yuan could do."

“能从此处进出，必有机关。”但他刚刚已经试过了，整个山洞都被百毒窟包围着，所以机关肯定是在里面。

所以该怎么进去将机关关掉呢？

此刻小灰已经找到了苏景湛二人，两人一鸟朝着正西方向走去。
