Heavy equipment plus a large amount of dry food and fat thirteen, weighing more than three hundred catties, Zuo Dengfeng is not easy to carry, but he has never thought about traveling lightly, these things are useful, even if he is tired now, he can't regret not carrying it at the juncture of use, he still understands the principle of carrying thousands of miles of weight and 10,000 steps.

Yufu sent away the iron shoes not out of selfishness of wanting to be alone with Zuo Dengfeng, but because she stayed and could give Zuo Dengfeng greater help, but if she didn't have any selfishness, it would be fake, more or less she still wanted to be alone with Zuo Dengfeng, and it was really bad to get a crazy monk in the middle.

This time the two did not go separately, because the further north, the more frogs, snakes, lizards and turtles, ordinary people are generally afraid of lizards and poisonous snakes, in fact, the poisonous frogs are more afraid than poisonous snakes, the two found a millstone-sized poisonous frog by the river, to be precise, it is a black toad full of tumors, it swallows poisonous snakes like a strong man eating noodles, the two immediately dodged when they saw it, and turtles, ordinary turtles are slow, harmless to humans and animals, but the turtles here are tusky and bite, When Zuo Dengfeng stepped on the back armor of a turtle, he was turned around and tore off his half-pulled trouser legs.

The keen intuition brought by the yin and yang trick makes Zuo Dengfeng feel danger at all times, danger is everywhere but there is no too powerful poison, the further you go north, the fewer woods and mountains, the abyss and sinkholes are dense, these abysses and sinkholes are bottomless, every time Zuo Dengfeng will venture down to check, most of the abyssal sinkholes below have a small amount of stagnant water, without exception crowded with a large number of poisonous snakes, these places are low, the temperature is relatively high, the snakes have begun to estrus, tens of thousands of poisonous snakes are entangled together and twisting and winding, The situation was horrific and disgusting.

Although Jade Whisk is an expert in using poison, he can't recognize all the varieties of poisonous insects here, and he can't detoxify them if he doesn't know the variety and origin, so the two of them are extremely careful along the way, and ordinary poisons are okay even if they bite the two, but some weird snakes and insects don't know how powerful their poisonous surnames are, so they can only avoid them.

There is a law in nature, that is, poisonous animals are generally not too large, so they will evolve poisonous surnames to protect themselves, and some large animals generally do not have poisonous surnames, because they have enough strength to kill animals, and there is no need to use venom, but this is not the case here, the giant snakes the thickness of the bucket are also bright red, and the triangular heads and fangs close to the foot indicate that they are highly poisonous.

Zuo Dengfeng had always felt that it was easier to find the ancient city of Puguo without anyone to disturb here, but now it seems that no one disturbed the ancient city, but it also made this narrow area between the Jinsha River and the Lancang River a paradise for reptiles.

Two days later, in the evening, the two finally discovered that a man-made building complex appeared a hundred miles ahead, because the distance was too far away, the two could not see the specific appearance of the building complex, but according to the scale of the building complex, it was the Puguo capital they were looking for.

Overjoyed, the two immediately sped up, but when they entered the 100-mile range of the ancient city, they found a strange phenomenon, there were no poisonous insects, no birds, not even beetles.

"Why aren't there any snakes in this area?" Yufu paused to observe the situation ahead, the ancient city was located in a flat area, close to the Langcang River on the west side, and there were no obstacles around.

"There are two possibilities, one is that the formation is working in secret, and the other is that there are extremely terrifying poisons around." Zuo Dengfeng said out loud, any poison with Taoism has its own fixed living area, in this area other poisons that are not as strong as it dare not approach, there are no reptiles, snakes and rats here is very likely because there are dangerous poisons here.

Hearing this, Jade Fu nodded.

"But at present, I have not found any traces of the formation, and I have not felt any danger." Zuo Dengfeng shook his head and said, after discovering the strangeness, the two of them did not dare to venture in, and they both understood the truth of the 10,000-year-old ship carefully, once they were trapped here, there would be absolutely no reinforcements.

"What now?" Jade Fu asked.

"Let me think about it." Zuo Dengfeng put down the wooden box and frowned and thought, the area in front of him was flat, it should have been cultivated land back then, and the cultivated land was overgrown with weeds after it was abandoned, but there was not a single tree here, this is not normal, if the water Yin Pig is in the ancient city in front of it, then it will definitely breed a lot of wood gas, and the vigorous wood gas will lead to dense forests, but there is no forest here, not only is there no forest, not even a big tree, this is not normal.

"The wood qi here is sluggish, indicating that the water is not spiritual, there are two possibilities for this situation, one is that the water yin pig is not here, and the other is that the water qi of the water yin pig is blocked by the formation." Zuo Dengfeng pondered for a long time and said.

Hearing this, Yu Fu nodded, waiting for Zuo Dengfeng to continue his analysis.

"I think the second one is probably bigger." Zuo Dengfeng frowned and said.

"What's the reason?" Yufu asked, she had already understood Zuo Dengfeng's speech habits after getting along with Zuo Dengfeng for so long, Zuo Dengfeng would say "I feel, I guess" when the reason was not sufficient, and only if the reason was sufficient, he would say "I think." ”

"Among the five elements, the grass is also wood, and the weeds here grow so luxuriantly indicates that they are affected by some kind of aura, but this influence is not caused by the water yin pig, because if it is a water yin pig, there should be tall trees, and now there are only weeds without trees, which means that the weeds are not affected by the yin pig, but by the wood poison that it breeds." Zuo Dengfeng said.

"You mean that the earth branch is within the formation, and the poison derived from it is outside the formation." Jade Whisk asked.

"Yes, similar to the situation of the rats and poisonous lizards, since the poison is in this area, it means that the ground is not far from here, and I can't feel its breath means that it is trapped in the formation." Zuo Dengfeng nodded and said.

"What are we going to do now?" Jade asked with a little hair.

"It's just the south wind, so set fire to all the weeds here so that you don't get ambushed." Zuo Dengfeng lowered his head as he spoke, igniting the weeds in front of him, these weeds were born last year, and they had dried up at this time, and immediately spread northward after ignition.

Seeing that Zuo Dengfeng said that he would do it, Yu Fu couldn't help frowning, there was no clear dividing line between this area and the surrounding area, and this fire would not only burn this area, but even a large area in the north would also be affected, Zuo Dengfeng's style of acting was both crisp and vicious.

"What if the trail is burned." Jade Fu frowned and asked.

"It's been three thousand years, and the clues that can be burned have long since rotted, but whatever is left behind will not be afraid of fire." Zuo Dengfeng put the flat wooden box, took out the dry food from it and handed it to Yufu.

Yufu glanced at Zuo Dengfeng, took it, and the two of them sat on the wooden box and watched the fire burn north.

After eating the dry food, Yufu fell into contemplation again, she has been comprehending the spell relayed by Zuo Dengfeng for the past few days, the more she thinks about it, the more she feels that these few hundred words are extremely mysterious, the so-called rejuvenation spell is simply the secret method of ascension, and the most important thing is that this spell seems to be tailor-made for her.

After a while, Zuo Dengfeng took the lead in standing up, and Yufu looked up to the north with a sense of feeling, and found that the mountain fire had spread to the distance, and the flames near it had been extinguished.

After packing up, the two of them looked north and swept away, and the distance of a hundred miles soon came to the end, and a strange city came into their eyes.

Since ancient times, the city is mostly square, surrounded by city walls on all sides, there are urn cities to protect, there are inner cities and outer cities in the city, but the city here is round, there is no moat outside, the circular city wall is built of bluestone, there are three zhang high, although it has been invaded by wind and frost for a long time, but there is no phenomenon of collapse.

The two came to the city and did not look for the city gate, but swept straight to the city wall, after the city wall, the two immediately froze, the interior of the city is also circular, there are ten miles of range, the right side is the house and the stone building inhabited by human beings, the left side is the blue lake, the buildings in the city and the lake in the city each occupy half of the area of the ancient city, and the shape is exactly the same as the Taiji diagram, it is a yin and yang city that has never been seen.

"Have you ever seen a city of this style before?" Yu Fu was stunned and turned to look at Zuo Dengfeng.

"I haven't seen it." Zuo Dengfeng frowned and shook his head, he was not as good as Yufu at all, he had only traveled south and north in the past few years, and he had never even been out of Wendeng County before.

"There are defects in the western wall." Yufu stretched out his hand and pointed to the northwest, the city walls of the other parts of the entire stone ancient city are very complete, only the west side has collapsed, this half of the city wall is piled up in the water, after the collapse, half of the lake in the city communicates with the Lancang River on the west side, and the connection is more than two miles wide.

Zuo Dengfeng nodded when he heard this, and then shifted his gaze to the lake on the west side, half of the water in the city is blue, and it is very deep without asking, there is a small island two miles square in the central area of the lake, there are many green trees growing on the island, the entire height of the lake is about two zhang lower than the waterless area on the right, the connection part is built out of a long arc-shaped stone platform by the bluestone base, the urban area on the right is all stone buildings, and it is extremely intact, and there is a pool of about two miles in the central part of the east city, The water is the same color as the lake on the west side, but the pool is connected to the lake on the west side underground, and the weeds growing and withering on the roads and the empty streets in the city indicate that this eerie yin and yang ancient city has been abandoned for many years.

"The east side is the area where people live, and the west side may be the place where the water belongs to the Yin Pig is sealed, or it may be the area where the mermaid lived before." After a long time, Zuo Dengfeng spoke.

"There doesn't seem to be any living creature here." Yufu nodded and said, it was already evening at this time, the sunset was shining, and the entire ancient city was dead silent.

"Yes." Zuo Dengfeng shook his head.

"Where." Jade Fu asked, looking around left and right.

"...... beneath the ancient city"
