"Zuo Dengfeng, what are you looking at?" The iron shoes saw Zuo Dengfeng looking down, and turned back from the front.

"This mountain peak is likely to harbor monsters." Zuo Dengfeng stretched out his hand and pointed down.

"Amitabha, what a monster." Iron Shoes asked curiously.

"I don't know, go down and take a look." Zuo Dengfeng's running aura fell to the east side of the peak, and the iron shoes followed.

The two of them were currently in no man's land, and there was no road to settle on, and they landed on a raised rock, surrounded by various broad-leaved trees, and the trees were overgrown with thorns and weeds, and it was difficult to move an inch here without volleying skills.

The pool on the east side is 100 paces wide and bottomless, but the water is clear, and the clear water means that there are no strange aquatic animals in it, otherwise the water will be very turbid.

After the two fell, the iron shoes released the boss, and still ran into the pool to swim to cool down, the boss is an aquatic animal, very afraid of heat, and has to bathe often.

Zuo Dengfeng has been looking at the boss in the pool, the boss has a habit, that is, he likes to catch fish, and he likes to show off, but in this pool, he has not caught any fish after several dives, which means that there are no fish here.

This mountain peak is not like the surrounding peaks are connected to each other, it is relatively readable, the peak is surrounded by four waterholes, there are miles of grass on the periphery, after falling, Zuo Dengfeng keenly felt that something was wrong, there were no beasts and birds singing here, and there was a dead silence around the huge peak.

The boss frolicked in the water for a moment before running back, and cooed twice at Zuo Dengfeng before jumping into the wooden box of the iron shoes.

"The boss will say hello to you." Iron Shoes smugly Chong Zuo Dengfeng smiled.

Zuo Dengfeng smiled when he heard this, but didn't speak, the reason why the boss smiled at him was because he was thinking about his Neidan, which was a flattering performance and not out of politeness.

"Let's go, find the monster." The wooden box on the back of the iron shoe rushed to the left and said.

"I'm looking for the southwest, and you're looking for the northeast." Zuo Dengfeng nodded, then volleyed into the air, crossed the waterhole and swept towards the peak.

It didn't take long for the two people who had survived the Tribulation to search for a mountain peak, and after a few moments, the two met in the northwest and found nothing.

"Amitabha, there's nothing, let's go." The search for iron shoes was fruitless, and it felt very boring.

"Among the five elements, Jin Kemu, the four waterholes here have spawned a lot of gold qi, and it stands to reason that there should not be so many trees in the mountains." Zuo Dengfeng frowned and shook his head.

Iron Shoes nodded in amazement when he heard this, his nod was just a response, and he could not participate in the analysis.

"The gold should be underground, not on the ground." Zuo Dengfeng suddenly realized, turned to the north in the air, and laid eight tree stumps in the southeast, northwest and northwest, these eight tree stumps took the path of the eight array diagrams, and did not need to correspond to the five elements of yin and yang.

This was the simplest formation, he wanted to set fire to the trees in the area, and the purpose of the formation was to stop the fire from spreading.

After the formation was arranged, Zuo Dengfeng put on the pure yang gauntlet, dried and ignited the green weeds, the trees in the mountain were very lush, and the fire was very slow at first, but the igniting flames dried the shrubs and weeds on the periphery, and the fire gradually expanded.

"Why did you set the fire?" Iron Shoes was reluctant to chase Zuo Dengfeng and ask questions, but he couldn't restrain his curiosity.

"There are two purposes, one is to overcome the fire and gold, I hope that the fire will force out the hidden metal animals in it, and the other is to clear the obstacles, there are too many bushes and thorns in the mountain, and it is possible to cover the hole leading to the ground." Zuo Dengfeng explained that the fire was burning from south to north, and the two of them were on the south side of the mountain at the moment.

The fire burned for more than an hour, and after the fire turned to ashes, Zuo climbed the peak to look for it again, and this time found a hole on the north side of the peak, near the top of the mountain, which was five feet wide and went diagonally downward.

"You stay here, I'll go down and see." Zuo Dengfeng unloaded the wooden box and said with iron shoes.

Iron Shoes nodded when he heard this, the hole was too narrow to allow the two of them to go down together, if one after the other, if there was a problem inside, the person below would not be able to quickly rise and escape.

Entering an unknown cave in an unfamiliar environment is an extremely risky thing, but Zuo Dengfeng jumped without hesitation, the boldness of the artist is part, and the other reason is that he feels that there is no danger in the cave, first, there is no trace of animals entering and exiting the cave, and secondly, there is no fishy smell coming from the cave.

It is impossible to see by outside light when descending five meters, but the left summit does not need to be illuminated by the sun, and the cave does not go straight up and down, but leads diagonally to the bottom of the mountain, so that the slope does not affect the animals that lived here up and down.

Walk more than ten meters, the cave appears to turn a corner, the cave is dark, in fact, the reason why people will have fear at night is because they can't see things clearly in the night, and they don't know the surrounding situation if they can't see clearly, so they are afraid, if they can clearly see the surrounding situation, people will be very bold, and there is no difference between night and day.

After sliding ten zhang, Zuo Dengfeng found a dark yellow scale in the crack of the mountain, the scale is the size of a wine cup, he thought it was a snake scale at first, but after careful inspection, he found that it was not as round as the snake scales, it should be a four-legged reptile similar to a four-legged snake, and at the same time found a half-broken iron sword tip in the crack of the scales, which shows that someone has been here before, and the tip of the sword has been seriously corroded, which indicates that a long time has passed.

The cave is deeper than Zuo Dengfeng expected, and the depth can no longer be determined later, Zuo Dengfeng finally stopped at the bottom of the peak, and in front of him is a wide area of 100 square meters, there is a dark river below, the river is five zhang wide, flows in the direction of east and west, the water flow is gentle, and the water quality is clear.

It is well known that the further down you go, the higher the temperature, because it is close to the scorching center of the earth, but the groundwater is cold, and the coolness of the water neutralizes the stuffiness of the underground and brings fresh oxygen, making this a pleasant place to be located underground.

This underground river is very wide, the upstream channel is narrower, the river begins to smooth here, the few sediments begin to deposit, on the south bank of the river piled up a small beach, said that the beach is not simply sand, there are many colorful things in the gravel, among which he knows the golden sand, he also knows the red and greenstone, the white crystals the size of the finger belly are similar to diamonds, but these crystals are unpolished, he can't be sure whether they are diamonds or not.

There is an animal skeleton in the middle area of the beach, most of the bones have been buried by the sand, only the torso and head are still exposed, seeing this head, Zuo Dengfeng is sure that his previous speculation is correct, this is a huge four-legged snake, unlike the poisonous lizard derived from the boss, this four-legged snake should not be able to run on two hind legs, but on all four claws.

Zuo Dengfeng approached the skeleton, squatted down and looked at its head, most of the animal inner pills were in the Seven Tricks Divine Mansion, that is, in the head, and its head was complete, which indicated that its inner pill might still be there.

Thinking of this, Zuo Dengfeng raised his hand and grabbed the head of the big basin, because the skull kept in the ground without being exposed to the sun was still very hard, Zuo Dengfeng raised his hand and forced, and the left and right sides broke the skull, and a yellow Neidan that looked like an apricot kernel fell out.

Zuo Dengfeng was extremely happy when he saw this, although the aura of the Inner Dan had already diverged over the years, most of the aura was still preserved, and it was much more pleasant to easily obtain the Inner Dan than to peel the skin and debone the killing ring.

The color of most of the Inner Dan is the same as the body color of the animal before its death, and the yellow Inner Dan and the yellow scales in the tunnel together indicate that this four-legged snake was yellow before its death, but the amount of Inner Dan stored Spiritual Qi is not proportional to the size of Inner Dan, and the Inner Dan of the twelve earthly branches is very small, but the Spiritual Qi is several times, dozens of times, and even hundreds of times that of these ordinary animals.

Putting Naidan away, Zuo Dengfeng lowered his head to pick up those gems in the sand, he was generous, he didn't care about money, he was once again penniless at this time, and after a while, when he was about to leave with what he had picked up, three depressions in the rock wall on the north side caught his attention.

The beach is silted on the south side, and there is no beach on the north side to stand on, so he climbed to the top of the mountain and swept lightly, and looked at the rock wall on the north side, and there were three circular pits the size of bowls arranged up and down the rock wall, and there were traces of tools digging around the pits, which showed that someone had dug up three round things here.

The circular pit is more than three meters high from the water surface, and only cultivators who have survived the catastrophe can dig things here, Zuo Dengfeng observed suspiciously for a moment, and did not find any clues to trace what the cultivator dug up here, but there is no doubt that these three things should be some kind of metal.

After a while, Zuo Dengfeng turned around and left, these things had nothing to do with him, and there was no need to delve into them.

"Amitabha, you're digging people's graves again." Seeing that Zuo Dengfeng had brought back a bag of red, red, green and green gems, Tie Shoe immediately frowned and chanted the Buddha's name.

"It's not a grave down there, it's a dark river, and these are the rivers rushing in, how can the things in the grave be so bright." Zuo Dengfeng lifted the lid and poured the gems and other things in his robe.

"What's going on down there?" Iron Shoes was relieved when he heard this, he followed Zuo Dengfeng to find a quiet play, if Zuo Dengfeng had been digging graves, he would definitely not follow.

"Four snakes were killed." Zuo Dengfeng took out the Inner Dan from his arms and handed it to Thirteen's mouth.

Seeing this, Thirteen raised his head and glanced at Zuo Dengfeng, Zuo Dengfeng smiled at it, there are no creatures around here that may be related to this Neidan, there is no doubt that this Neidan is highly poisonous, but Thirteen is not afraid of a hundred poisons, sniffed for a moment and opened his mouth to swallow the Neidan.

"Let's go." Zuo Dengfeng said with a wooden box on his back and iron shoes.

"What did you give Thirteen to eat?" Iron Shoes asked curiously.

"The four-legged snake's inner dan can help it accumulate aura." Zuo Dengfeng said casually, it takes time to digest Neidan, and there will be no obvious changes in the thirteenth short period of time, "Be obedient, I will help you find Neidan in the future." Iron Shoes touched the boss's head, "Oh, no, the old man can't kill." ”

"The concentrate has to be fed to Maxima, and the donkey eats it and wastes it." Zuo Dengfeng carried thirteen qi and flew to the northwest.

Iron Shoes didn't understand what Zuo Dengfeng's words meant, and followed behind with the boss on his back.

After climbing over a few hills, Zuo Dengfeng saw the ruins of the ancient city of Yongguo in the northeast, and this discovery made him suddenly understand what the underground cave was dug up......
