The effect of the poison spell is not permanent, but time-limited, so the two of them did not waste any time, and immediately took the carriage that Nie You had already prepared and headed towards the west of the border deserted city.

After leaving the city, the carriage entered on its own and went to the border wilderness to worship another demon king. Only then did Lin Cheng know that the Water Mansion was originally in the mortal city of the Qingyang Kingdom realm.

Five days later, the two of them walked all the way, passing through several small cities in Qingyang Country in a row, bypassing a large city, and arriving at a small mountain range adjacent to the foothills of Canghuang Mountain. Since there was no road ahead, the two immediately abandoned the carriage and headed for a mountain town that could be seen in the distance.

The name of the mountain city is Sanyang City, which is exactly what Nie You said, and there is a mortal city at the bottom of the well.

In the middle of the night, the lights and moon disappeared, and there were no lights in the city, so the two quietly entered the city.

Although this city is a small mountain city with a population of less than 10,000, there are still a few local tyrant-like demon tail families, and there are no demon tail warriors.

Inevitably alarmed the demon tails in this city, and there was no trouble in vain, and the two of them did not dare to be careless at all.

"This is the well!"

Touching a large family with nearly 100 livestock in the west of the city, Nie You killed the fierce dog guarding the yard with rune paper, pointed to an ordinary well surrounded by a wooden fence in the corner of the wall, and said to Lin Cheng.

"Oh?"

When Lin Cheng heard this, he climbed over the fence and leaned over to look into the well, only to see that there was water in the well at a depth of one zhang, which looked ordinary, did not look old at all, and did not look unusual. Even if he didn't use the power of the spirit pupil, his eyesight far surpassed Nie You, and he didn't even see the slightest clue.

Although Nie You looked short and old, his movements were very flexible, and he easily climbed over the fence that was twice as tall as him, and said unequivocally to Lin Cheng: "Why don't I go down the well!" The old family name is just restrained by the water, and can only barely avoid the well water with the water avoidance charm, and then it will all depend on Xiaoyou's underwater efforts to drag it!"

Lin Cheng nodded, and immediately supported the wall of the well with his limbs, and slid down dexterously, and soon submerged into the cold well water.

Seeing this, Nie You took out a talisman with blue light stripes and stuck it on his chest, and sharp and thin nails appeared on his hands, and he actually climbed directly down the wall of the well into the water.

As soon as he entered the water, the water amulet on his body was effective, and a blue brilliance emanated along his body, avoiding the well water.

Then, the two of them plunged directly into the water and dived to the bottom.

When he was about to reach the bottom of the well more than ten zhang deep, Nie You motioned for Lin Cheng to no longer dive, but attached himself to the wall of the well, and carefully touched the surroundings a few times.

When he finally found something, he took out a bronze key that was more than a foot long and inserted it into a tiny hole where his finger was pressing.

"Bang bang bang!"

Nie You twisted the key to the left and then to the right, but when he heard a dull low sound, he actually opened an iron door three feet thick on the wall of the well, where no trace could be seen with the naked eye.

Before the iron door was fully opened, a stream of water immediately poured out from the crack in the door, and after more than ten breaths, it finally stopped, exuding a rich water breath.

Nie You didn't immediately take Lin Cheng into it, but took out his copper abacus, "pop papa", and quickly counted something.

Soon after, the old man came to his conclusion, and pulled out many Sumeru bags from his waist, and filled them with water one by one.

Lin Cheng realized that the old man was calculating how much extra water was in the well, and in order to avoid being seen, he filled the extra water away and restored the original water level of the well.

After Nie You filled more than ten bags of water in a row, the two of them entered the round iron door one after another, and Nie You used the long key to lock the iron door again.

"Huh!"

Lin Cheng looked at it and couldn't help but take a breath of cool air. I saw a circular water hole the thickness of a water tank, like a thick long snake, diagonally leading downward, and disappeared into the thick darkness, I don't know where it leads.

He touched the walls of the cave with his hand, and felt that it was a rough and hard stone, with a faint smell of decay, as if it had existed for an extremely long time.

"Let's go! The water house is at the end of this water hole. ”

Nie Yu was familiar with it and took the lead in swimming downward. Seeing this, Lin Cheng followed.

The further down he went, the more strange Lin Chengcheng felt, only to see that the water hole was gradually becoming thicker. You can't find it in the process of swimming, but if you think back to the thickness at the beginning, you will be surprised by the difference.

It's like a branch growing from the trunk of a tree, and the closer you get to the trunk, the thicker it becomes. If you look at it little by little, you won't see anything. If you look at it, you can see the difference between the thickness of the end and the root.

With the continuous dive, Nie You continuously superimposed several water avoidance charms to avoid the increasingly powerful water pressure, and at the same time, he was also amazed by Lin Cheng's extraordinary underwater skills.

After three hours, the diameter of the water hole had reached more than half a zhang long, and the water pressure had increased nearly tenfold.

Nie You took out a few Bright Demon Spirit Beads and added them to a rare water-proof lamp, emitting a soft white light, but it could only illuminate a distance of more than a zhang. Obviously, the water mansion he was talking about should be near.

"Next, you still need to take care of Xiaoyou, although the old decay can use the power of the water avoidance charm to ensure safety, but the action is a little inconvenient. ”

Nie You said, took out a long rope made of beast warp with the thickness of his thumb, handed one end to Lin Cheng's hand, and tied the other end to his waist.

One of the biggest roles he had to play on this trip was to take Nie Yu into the water, and at this moment, of course, he would not be ambiguous, so he immediately tied the rope around his waist and continued to dive down diagonally.

"Sure enough, there is a water mansion!"

Not long after, Lin Chengcheng saw that in the deep water of more than ten zhang, there was a pale blue mottled stone wall, which just blocked the entire circular water hole.

Above the stone wall, there was a small square door, with a clearly visible grooved outline around it, and a swallowing ring with a lion's head on the door.

Lin Cheng used his hands and feet at the same time, pulled Nie You, and cautiously continued to dive, unknowingly raising the "double vertical eyes" above his head, not daring to be careless at all.

Since the last time he was almost taken away because of that life-control talisman card, Lin Cheng's originally cautious surname has added an extra eye, and he has not given up his guard at all because he has multiple means to save his life. Especially in such ruins of unknown origin, the vigilance is even more aggravated.

More than half an hour later, the two of them arrived at the stone gate, and they did not encounter any danger. I saw that although there were grooves around the stone gate, it was very tight. In the lion's mouth under the swallowing ring, there was a column of water the thickness of a thumb gushing out of it. It seems that all the water in the water hole is formed by the collection of this stream of water......

Lin Cheng turned around and pulled Nie You closer and said, "Elder Nie, what now?"

Nie You took out a few higher-quality water amulets, and after sticking them on his body, he exhaled a few times, coughed a few times, and said, "Ahem, thank you Xiaoyou, just hand it over to the old man next." ”

Nie You said, with a look of excitement on his face that could not be concealed, he actually took out another key more than a foot long, lifted the swallowing ring on the door, and inserted it into the lion's mouth against the water.

He twisted the key three times in succession, but with a heavy whimper, the small square door opened outwards of its own accord, and a stream of water rushed out, swinging them both more than a foot high.

However, the current lasted only three breaths, and after three breaths, it quickly returned to calm, leaving only a dark square hole.

"Little friend, let's go in!" Nie You's eyes sparkled, staring at the square door hole as if he was looking for it, and said in a trembling voice.

When Nie You opened the first door, there was a key, which Lin Cheng was not surprised by. After all, according to him, he has kept this secret for decades, and it is not impossible to install an iron door.

But when he arrived at the door of the second door, Nie You actually had another key, and this door was obviously not an existence that he could build, which made Lin Cheng have to be suspicious.

However, he did not immediately say the doubts in his heart, but did not change his face, and took Nie Yu into the square door.

Lies are almost always based on conspiracy, and since this person still hides something from him after all, it is very likely that he harbors evil intentions. Even if the poisonous charm is used as a restraint, you must have another mind and be on guard.

The further down he went, the more strange Lin Chengcheng felt, only to see that the water hole was gradually becoming thicker. You can't find it in the process of swimming, but if you think back to the thickness at the beginning, you will be surprised by the difference.
