The keys to all the iron doors are in Situ Juntang's hands. Judging from how skillfully he took out the keys and opened the locks, and from the fact that there is not much dust covering the iron doors, we can guess that he must have been here frequently.
Every time he entered an iron door, Situ Juntang would lock the door and explain to Li Xuan that this was to prevent zombies from entering the ground.
Li Xuan understood it very well and felt that this measure was safer.
After all, the survival of hundreds of thousands of people in Youzhou City is at stake, so no matter how cautious you are, you can't be too cautious.
Compared to Li Xuan's calmness, Situ Mei's face was full of horror. She had long known that there was a basement in her home, but she had never been allowed to enter.
This was the first time she had entered a basement, and it was also the first time she had entered such a deep underground place. Seeing that there was such a huge project in the home she had lived in for many years, she felt incredible every step she took.
On the seventh floor, the three of them walked through the seventh-floor basement. After opening and closing seven iron doors, they finally saw a deep stone cave with an end that was hard to see.
Situ Juntang raised his hand and groped for a few times on the dark stone wall, then he heard a series of muffled sounds of "puff, puff, puff", and a row of bean-like lights lit up in the cave, leading to a dark and unknown place.
"Going to the end ahead, there are three levels to defend against the corpse disaster.
The last time I came here was half a year ago, and I was poisoned by the corpse poison that time... According to the rules, this place should still be peaceful for half a year."
Situ Juntang said.
"You did well."
Li Xuan nodded in approval.
"I'll take Mr. Fire over there...cough cough cough!"
Situ Juntang suddenly coughed violently, and there was a faint trace of blood in the phlegm he coughed up.
"Your body has just recovered and is still too weak to waste any more energy and energy."
Li Xuan said, "Well, I'll go over and take a look myself, and you guys can rest here."
"How about that?"
Situ Juntang reluctantly held on to the cave wall and wanted to lead the way, but after taking two steps, his knees went weak.
"Grandpa, please stop forcing yourself."
Situ Mei said hurriedly.
Situ Juntang took a few deep breaths: "Xiao Mei, go with Mr. Huo.
It’s time for you to familiarize yourself with the responsibilities of our Situ family and take a good look at everything inside. When you come back, I will pass on the secrets guarded by the Situ family to you!"
By now, Situ Mei had guessed something. Hearing this, he nodded firmly and said, "Okay, I'll go take a look!"
Leaving Situ Juntang behind, Li Xuan and Situ Mei walked in the narrow cave. Although there were dim lights every dozen steps, this deep underground environment still gave people a heavy sense of oppression.
Suddenly, Situ Mei listened attentively: "What's the sound?
Why does it seem like... there is the sound of water?"
"It's an underground river."
Li Xuan said calmly.
"Why do you seem to have been here before?"
Situ Mei asked strangely.
Li Xuan did not answer. Although his Feng Shui skills were not as good as those of the Feng Shui masters in the Immortal World, they were not comparable to those of ordinary immortals.
The bottomless corpse cave, the Nine Yin End, must be followed by a river of underworld! The further they went, the clearer the sound of water became, and suddenly the two of them stopped.
The lights on the cave wall ended here, and the dim light could only extend for two or three meters before being swallowed up by the boundless darkness.
Situ Mei took out a luminous pearl and blended the spiritual energy into it, which immediately released a beam of soft light. When she saw everything clearly in the darkness, she couldn't help but exclaimed.
She and Li Xuan were at the exit of the cave. There was a cliff three meters outside the cave. Standing on the cliff and looking down, a rapid underground river was making a loud rumbling sound, impacting the rocks underground, and flowing along the ground.
The seams flew by without knowing where they were going.
Opposite the cliff, twenty meters away is another cliff, and the two cliffs are connected by a rickety cable bridge.
It is said to be a bridge, but it is actually twelve iron chains with different wrist thicknesses and staggered heights. They are firmly nailed to the stone walls of the cliffs on both sides. When they shake, they will collide with each other and make a crisp sound.
What shocked Situ Mei was not the Dihe River and the cable bridge, but the huge mechanism under the bridge.
Just seven or eight meters below the chain bridge, there is a huge gear covered with sharp blades sandwiched between the cliffs on both sides. It rotates continuously with the impact of the current of the underground river.
The light of the flashlight shines on it, and the blade of the gear reflects back the dazzling light.
Situ Mei stared blankly for a long time and couldn't help but ask: "What is this for?"
Li Xuan said: "The layout of this mechanism is quite exquisite..." Although the chain bridge is dangerous, it is not a difficulty for immortals. Even ordinary people can maintain balance with two feet under their feet and a few in their hands.
Safe passage.
But for zombies with low IQs, the chain bridge is a chasm that is difficult to pass.
When they step onto the swaying iron rope, they will inevitably fall and be instantly strangled to pieces by sharp-edged gears.
This is a mechanism designed to cleverly take advantage of the difference in intelligence between humans and zombies. A lot of thought must have gone into its original construction.
"Me first."
Li Xuan jumped onto the iron rope with joy. Under Situ Mei's stunned gaze, he easily crossed the 20-meter cliff and flew over the sharp gear blade.
Then there is Situ Mei. Her cultivation level is actually higher than that of Li Xuan. After overcoming her psychological fear, walking across the chain bridge is naturally a piece of cake.
"Why are there these institutions?"
Situ Mei stepped on the ground, breathed a sigh of relief, but immediately asked.
Li Xuan pointed to the deeper and darker cave in front and said: "There is an extremely terrifying underground cave inside, where thousands of zombies live.
You have also seen zombies in the Huangquan ruins. In fact, the zombies there are just childish compared to here.
These zombies will want to rush to the ground from time to time. If it weren't for these arrangements and the hundreds of years of persistence of your Situ family, Youzhou City would have been captured long ago."
Situ Mei stayed for a while, then gritted her teeth and said, "I'm going to see those zombies."
They continued to walk forward. It was pitch dark here and could only be illuminated by night pearls.
Suddenly, Situ Mei exclaimed: "Who is that person?"
Li Xuan also saw at a glance that in the narrow cave in front, there was a person who seemed to be resting with his back against the cave wall! Who would rest here?
It came out of nowhere! Could it be a zombie?
Several guesses suddenly popped up in Situ Mei's mind, and her palms were covered in cold sweat.
Li Xuan was also stunned for a moment, and then said: "Don't be afraid, it's a corpse."
"Not a zombie?"
Situ Mei was dubious.
"Well..." Li Xuan said.
The two walked over, and under the light, it became clearer and clearer.
Sure enough, it was a skeleton that had been dead for a long time. The flesh and blood and clothes had long since rotted away, leaving only the skeleton.
Situ Mei asked in surprise: "Who is this?"
Li Xuan raised his hand and ignited a ball of moon-white flame, shined it on the cave wall and said, "Here, look."
There is a shallow pit dug by hand on the wall of the cave. Inside is a tablet with a row of large red characters.
"Gu Yinghua, the twenty-fourth generation of the Situ family!"
"Grandpa!"
Situ Mei looked at the memorial tablet in disbelief, her knees softened, and she fell to her knees with a bang.
