The Yinsha River flows eastward, and when passing through a bay, a tributary several zhang wide joins the river, and this tributary is the connecting channel between Wulongtan and the Yinsha River.

The water of Oolong Pond comes from the waterfall on the mountain cliff, not the water injected by the Yinsha River. Gao Cheng also came here to know that Oolong Pond was located above. He swept his gaze, and there were very few wild beasts near the pool to drink. The surface of the water seems to be shrouded in a light mist. The water vapor is hazy.

"Yu Qing once reminded me not to come to Oolong Pond, it seems that there are some problems here, but yes, there is an alchemy furnace of the Antarctic Immortal Weng hidden in Oolong Pond, it must not be that simple!"

Just now, he was severely injured by the old man incarnated by the mountain god, and his head was still tingling, and he needed to recuperate, heal his injuries and then go to explore the movement of the waterhole.

Gao Cheng didn't act rashly for the time being, and then found a hidden place, and began to run the water yuan to practice the blood meridian, constantly using mana to nourish his divine thoughts. With him running the exercises, a trace of spiritual energy quickly gathered, and it was endlessly devoured and refined by him. The concentration of aura here is about the same as that of the Silver Sand Cave Mansion occupied by the clam for thousands of years.

Most of the aura gathered came from Oolong Pond, and Gao Cheng noticed this when he was cultivating, and secretly paid attention to it.

In the blink of an eye, two days passed.

Gao Cheng continued to refine his aura, and the injuries he suffered had fully recovered, he stood up, moved his body for a moment, and then plunged into the Oolong Pond.

The water seems to be deep and calm, but it is actually a bit hot, and the further down you go, the stronger the feeling. Gao Cheng urged the demonic qi shield to protect the whole body, and kept diving, there were no aquatic plants and fish and shrimp in the pool water, and there was a little red in the extreme depth.

"Ahead is where the alchemy furnace is!"

Gao Cheng's spirit was shocked, and he accelerated his diving, and soon came to the bottom of the pond dozens of zhang deep, the strange rocks at the bottom of the pond were craggy, these stones were shaped like inverted stalagmites, one in the east and one in the west, there was a stone platform in the center of these stones, and an alchemy furnace was enshrined on it.

The alchemy furnace is a three-legged round dome, and there are several vents on the top cover, from which you can see that there are still raging flames inside the Dan furnace.

The reason why there are no fish and shrimp in Oolong Pond and the water temperature is extremely high should be because the fire of the alchemy furnace is constantly escaping from the vents.

"This is the legendary Alchemy Furnace of the Antarctic Immortal! It is definitely a good magic weapon!" Gao Cheng released all his spiritual power and carefully sensed the surroundings, the more critical it was, the more he couldn't be careless.

"Huh, what is this?"

Gao Cheng's eyes suddenly froze, and he saw long snakes with two finger-thick thicknesses, one black and one red, circling on both sides of the alchemy furnace. The bodies of these two long snakes are crystal clear, like two jade carved creatures, and they look very delicate.

However, Gao Cheng's powerful spiritual power could sense that these two thin snakes had extremely pure energy hidden in their bodies. They hovered in a crevice in a stone, as if they were sleeping, and as they breathed, they slowly absorbed the heat from the Dan furnace.

"These two thin snakes seem to have eight or nine hundred years of mana!" Gao Cheng secretly urged his mana, constantly condensing the three yin arrows, and waved his hand violently, and with a bang, dense black water arrows roared out, instantly blasting the stone cracks where the two thin snakes were hiding into powder. The two thin snakes were hit, and the crystal body appeared with blood marks, and they instantly woke up from their slumber.

"What dare you sneak up on our brother?"

These two thin snakes had already given birth to spiritual wisdom, and they were suddenly attacked by a sneak attack and were extremely angry, and when they saw Gao Cheng not far away, they suddenly turned into two thin lines, one black and one red, and tore at his body.

Gao Cheng's heart sank, these two thin snakes are so fast. If it's an ordinary youkai, they will bite to death when they don't react. This kind of monster can only be dealt with by a demon king with thousand-year-old mana.

He didn't dare to keep it, and immediately used his strong spiritual power to directly carry out a spiritual impact on these two thin snakes, boom! Silent explosion, the mana of the two thin snakes was pure, and the speed was extremely fast, but like other monsters, there was no cultivation technique, and when they encountered this kind of spiritual power attack, they would be hit.

Golden opportunity!

Gao Cheng's eyes lit up, the two thin snakes were rushed by the spiritual power, and suddenly paused in the water, and he immediately released the three yin arrows again, and the continuous bombardment directly bombarded the two thin snakes into four......

Then he released two Dao Fetal Seeds, refining all the pure mana of these two monsters into energy, preparing to slowly refine them when he had time.

After there was no danger, Gao Cheng came to the side of the Dan furnace and carefully examined this treasure. The Dan furnace is carved with divine patterns, and there is a raging inextinguishable flame inside. It looks quaint and unusual.

"How do you get this treasure out?" Gao Cheng circled back and forth around the Dan Furnace, tentatively holding the Ding Ear of the Dan Furnace with his hand and trying to lift it up, but he felt that this Dan Furnace had the weight of a mountain, and he couldn't shake it with all his strength.

After trying several methods back and forth, Gao Cheng also used his mind to probe into the Dan furnace, but he didn't expect that the flames in the furnace were nothing, and he almost poured into his mind with his spiritual power.

Standing on the stone platform where the Dan furnace was located, Gao Cheng frowned tightly, could he just enter Baoshan and return empty-handed? He stroked the divine pattern on the Dan furnace with his hand, and was in a bad mood.

After a while, his fingers suddenly trembled slightly, Gao Cheng's mental power was very sensitive at this time, and he immediately reacted and looked at the divine pattern that his fingers caressed.

"The divine pattern on the Dan furnace seems to be hiding something?"

Gao Cheng's heart moved, and thousands of fate points turned into energy to bring his consciousness into an illusory space. In this space, Gao Cheng arranged the divine patterns on the Dan furnace in the void. Then, under the unpredictable effect of the power of fate, these divine patterns continued to tremble, turning into golden tadpole texts.

"Xiao Tiangang refining treasure trick!"

These tadpole texts actually concealed a technique, and when these tadpole texts appeared, they flashed in the illusory space, and they turned into golden streamers and entered Gao Cheng's mind. It was deeply imprinted in his consciousness.

After a long time, Gao Cheng came back to his senses from the illusory space, and looked at the alchemy furnace in front of him, his eyes were a little complicated, it turned out that under this alchemy furnace, this crack was suppressed.

I don't know how many years ago, a master with mana to the sky refined this magic weapon, used the magic weapon to suppress the cracks in the ground, and constantly extracted the magma flames in the cracks, protecting all living beings in a radius of thousands of miles.

Now I don't know how many years have passed, the vicissitudes of the sea, the cracks in the ground have gradually healed, and this magic weapon also contains countless flames, if you move rashly, you will be incinerated into ashes by the flames in the Dan furnace.

"It seems that only the fire baby and the water baby in the gourd brothers can solve the flame in the Dan furnace!Fortunately, I didn't come in vain this time, and I got a technique for refining magic weapons!" Gao Cheng sighed helplessly, the tadpole text just now hid a lot of information, except for one exercise, it was the origin and function of this Dan furnace.

There is a set of Tiangang forbidden methods in the Xiao Tiangang Refining Treasure Duel, and there are a total of thirty-six changes in this set of forbidden methods, each of which corresponds to the refining method of a magic weapon. It is a legacy deliberately left by the owner of the alchemy furnace, of course, the owner of this alchemy furnace is not an Antarctic immortal.

As long as he has enough materials and strong mana, he will be able to refine more magic weapons in the future, thinking of this, Gao Cheng's frustration about not being able to get the Dan Furnace has also eased a lot.
