The sword was two feet eight inches long, weighed more than ten catties, and the spine was thicker than the usual sword, and it emitted a bright essence under the illumination of the night pearl. As soon as Yuan Cheng moved his hand, he felt that this sword contained extraordinary energy, and it was definitely not made of the same ordinary mortal iron. He casually slashed at the sea monster's skull, and wherever the sword went, it was like cutting tofu, and it was an extremely sharp sword.

Everyone had the color of their tongues, and they were overjoyed, so they took the sword and walked forward, and more than ten meters ahead was once a cliff, and it was also very close to the whirlpool. There are many caves on the stone wall, under the influence of the whirlpool, the local water flows in, and the local hole flows out, and there is one of them about three people high, and the cold air that can almost freeze people comes out of the cave, presumably the Xuan Bing Iron is inside.

At this time, Ma Meng and Bailong also came down, and at the same time lifted the tin plate and followed behind, Yuancheng hit the head, and their people followed closely and advanced to the cave, how dare they stay for too long, otherwise except for Yuancheng, their families would not be able to stand the cold.

The cave is even more wide, there are many strange stones in the area, the cold is even more pressing, if it is not at the bottom of the sea but at the bottom of the lake, the water has long been frozen. There are a lot of flat and gentle boulders in the cave, like a situation with different angles, the brilliance of the night pearl is reflected, the light and shadow are psychedelic, and it is much brighter.

Yuancheng looked around, but he didn't see the Xuanbing Iron, and everyone divided it up to investigate, but there was nothing particularly eye-catching in the cave. It's all the same cold here, and it's hard to tell where. Yuan Chengcen fell silent, relaxed his body, and groped with his divine sense, and the coldness of the public was very different, just one place was much colder, and at the same time there was an unusual smell of energy, which made people feel like they were plunged into the ice and snow world.

He followed the smell and stopped in front of a boulder four or five meters high and more than ten meters long, and the extreme coldness was in this area. Ma Meng, Yan Jiang, Bai Long, and Zheng Hao also surrounded and stood in front of the stone as big as a boat. Most of the stones in the cave are very gentle, but this boulder is particularly rough, some places like coral reefs, some places like ash poured out, and there are sea bathing aquatic plants and so on.

Yuan Cheng took the newly acquired sword and cut it on the stone a few times, and the reef aquatic plants fell in response to the sword, and the inside was a crystal pearl color, not too hard. Yan Jiang suddenly rejoiced and encouraged, with a look of surprise on his face, pointing to the boulder Dabi gesture, but no one understood what he meant, Yuancheng saw that he meant to cut it, which was exactly what he wanted, so he used his strength and slashed down with a sword.

The sword carried a long sword light, four or five feet long, and in a flash it all sank into the stone, cutting a large gap, and a stream of white light burst out with an extremely cold and cold air. In the blink of an eye, Yuan Cheng felt that his sword and right hand had been frozen, and if it weren't for his deep skill, they would have been frozen into ice cubes.

At this time, the boulder shook, and all cracked in another place, white light burst out, and the cold air was fierce, forcing everyone to retreat, and several ice crystals shot out from the cracked place, covering Yuancheng, who bore the brunt of the attack.

Yuan Cheng was surprised to think that this boulder was really a living creature, and he wanted to dodge it, but he could only use the sword, swing the sword like a wheel, and drive the sea water to form a rotating water shield to block those arrow-like ice crystals. By this time he had seen that the cracked place was crystal clean, full of pearl color, and inside was clean mussel meat, which was indeed an unimaginably large mother-of-pearl!

It is very likely that the Sexual Ice Iron was once swallowed by it, and its limbs were too big to get out of the cave, so it settled here.

The circle formed a square to block the ice crystals, and the sea water suddenly swirled forward, and a vigorous attraction was emitted from the mother-of-pearl, trying to suck him in. He stood on his feet as if he were cast in a lot, and did not waver for half a minute.

The whirlpool grew larger and sharper, and the gravitational force increased again, but at this time, the ground under Yuancheng's feet could not withstand the tension and loosened, and he started to slide into the giant clam. At this moment, two tentacles suddenly stretched out from the giant clam and rolled towards him like two giant whips, trying to pull it into the giant shell. If he was pulled in, he would have froze to death, if not to be caught in the trap.

Yuan Cheng swung his sword and slashed, cutting off both tentacles and jumping on the ground. Mother-of-pearl was taken aback, and suddenly closed the huge shell again, and the pulling force was completely eliminated.

Yuancheng was slightly loosened, but after a while, the other four people were frozen and were not very flexible and could not come to fund. If you can't solve this big guy quickly, you can only run for your life.

It seems that the striking power of this mother-of-pearl is not very strong, it is too cold, and the shell is too hard, but with the newly won sword, these two points are difficult to complete. He ran the Stability Technique, turned the Qi Heart Sutra into fire attribute true qi, and slashed and stabbed the giant clam with all his might, and each sword could cut a big crack, and the sword saw the flesh.

Although the mother-of-pearl has lived forever, it is much more intelligent than the usual pearl oyster, but no matter how big it is, it is still a shell, and it still carries its nature, and the more it is hurt, the more it shrinks tightly, and it dares to reach out and strike again. So he let the circle be cut and cut, and the huge shell that was two or three feet thick was cut piece by piece, and then the flesh inside was chopped off piece by piece. In the end, the tip of the sword touched a hard object, and when he turned it again, he picked it out, revealing that it was a slightly round piece of ice iron the size of a foot!

It's just that the color of this piece of ice iron is slightly different from the one recorded in the book, not like a semi-crystalline ice, but with a faint pearl color and brilliance. In view of the fact that it was swallowed by mother-of-pearl for eternity and penetrated into the nacre, it was not a single Xuanbing Iron that used to exist, and it is more appropriate to call it Pearl Xuanbing Iron, as for whether it has another effect, Yuancheng is unknown. Because Xuanbing Iron used to be an extremely rare divine iron, and the matter of being swallowed by the Mother of Pearl for eternity has never been recorded, and perhaps it has never been issued in the first place, who can know what the effect is?

Yuan Cheng didn't dare to be lazy, so he hurriedly went to the entrance of the cave to pull in a tin plate mixed with several secret medicines, unfolded it, cut off a piece, covered it with pearl ice iron, and then wrapped it up. He originally thought it was very large, so the tin plate was also very large, and now there was more than half of it left, so he rolled another layer, and the cold air of the ice iron was completely isolated.

Ma Meng and the others were almost frozen, but at this time, Yuancheng isolated the Xuanbing Iron and helped them thaw it with the fire attribute true qi, and then they came back to their senses. They have long coveted the night pearl outside, just because the task is not completed, how dare they dig it, at this time the task is completed, one by one hippie smiles, lift out the ice iron, take advantage of the effect of the water avoidance charm, busy digging the night pearl outside.

Yuan Cheng walked around the cave for a while, and did not see anything of other value, and his eyes fell on the vigorous mother-of-pearl, such a big mother-of-pearl, there should be pearls in it, right? He took a sword to dig up the shell of the mother-of-pearl one step further, and then cut the shell meat piece by piece, without the Xuanbing iron, the shell meat was cold and could not freeze him, and after digging for a long time, he openly found a fist-sized cold night pearl, which was so bright that all the caves were like a full moon night. The few night pearls that were dug up were once rare in the world, but when put together with this one, it is simply that the stars are better than the moon, not a grade.
