The carapace of Xuanwu is round, the length and width are more than 200 meters, different from the carapace of turtles in the ocean, the carapace of Xuanwu is more similar to the king eight of freshwater, it is flattened, there are many bone spurs on the upper part of the carapace, the length and thickness of the bone spurs are different, and it looks like a small hill carrying a stone forest as far as the eye can see. Xuanwu's limbs were similar to those of a reptile, as thick as elephant legs, seven feet long, and the huge limbs had sharp claws at the ends, and the four black chains of the thickness of a child's arms locked its limbs respectively, and the four chains were now straightened, indicating that Xuanwu had risen to the limit of its range of motion.

After seeing the tortoise shell of Xuanwu, Zuo Dengfeng quickly dived close, climbed the bone spurs above the tortoise shell to find, the area of the tortoise shell is very large, the size of the bone spurs is uneven, the longest can reach more than ten meters, there are a large number of foreign bodies such as earth and stones attached to the gaps of the bone spurs, due to the age, many foreign bodies have been adhered to the bone spurs.

Because basalts have a large number of bone spurs, the bone spurs often scratch the rocks on the bottom of the sea when they move, and some of the fallen rocks are stuck in the cracks of its bone spurs, and the meteorite may have been cut down by it and stuck in the bone spurs, rather than directly falling on its back.

These rocks are stuck in different positions and angles, so that Zuo Dengfeng can not search at a glance, so he can only search up and down from the gaps, looking left and right.

Because the sea water has been polluted, the moss has died, and the rocks where the bone spurs are stuck are not moss-attached, but they all have shells left behind after the death of shellfish, and the shells hide the original appearance of the rocks.

Meteorites burn during the fall, and after burning, there are dense holes left, which is a way to identify meteorites, but the rocks entrained in the bone spur crevices are covered with shells of different sizes, and it is impossible to distinguish them at all.

In addition, according to the big head, meteorites are black, which is another way to identify meteorites, but most of the rock shells exposed under the bone spurs are black, and the color cannot be used as a criterion for distinguishing meteorites.

Zuo Dengfeng quickly filtered various methods in his mind, and felt that there was only one way to work, that is, to use a dagger to cut off the various shells attached to the outside of the rock, and observe whether the rock had any pores produced after burning.

This is the most stupid method, but there is no other way, due to the large number of rocks entrained by bone spurs above the turtle shell, Zuo Dengfeng did not dare to rub for a moment, and poured the spiritual energy into the dagger to quickly cut the rocks.

The range of more than two hundred meters is at least entrained with hundreds of rocks of different sizes, and it takes a lot of time to check them one by one, and ten minutes is definitely not enough, Zuo Dengfeng couldn't help but start to be impatient, but unfortunately the instrument of the big head cannot be used underwater, otherwise it can save a lot of time.

Thinking of this, Zuo Dengfeng suddenly remembered that the big head had tested here with an instrument before the Xuanwu floated, and found that there was no response, there are two possibilities in this situation, one is that the sea water is too deep for the instrument to detect the meteorite. The second is that there are very few meteorites left, and they are located deep enough on the ocean floor to be detected by instruments. Of course, there is a third possibility, that is, there are no meteorites here, but Zuo Dengfeng is reluctant to consider this possibility.

On the whole, the second possibility is the largest, after all, Ji Xian and others have collected meteorites on Xuanwu's back, and there will always be a little left, and it is impossible to cut them so cleanly, that is to say, meteorites are likely to be there, but they are not big.

Thinking of this, Zuo Dengfeng no longer inspected those large rocks, but used a dagger to cut those rocks that were smaller than the size of a watermelon, and the inspection speed was greatly accelerated due to the narrowing of the scope of the inspection.

After a while, Zuo Dengfeng made a new discovery, the rock entrained on the basalt back was hard, and the fragments were angular and angular, which indicated that these rocks were basalt that formed the crust of the ocean, and the meteorite fell from the sky and did not have edges and corners after burning. This discovery caused Zuo Dengfeng to narrow down the search area again, abandoning the small rocks with obvious edges and corners, and focusing on the more rounded ones.

Most of the small rocks are stuck at the root of the bone spurs, which adds difficulty to the search, halfway Zuo Dengfeng found that the oxygen in the chest was exhausted, and bit the hose to ventilate the skin, but the air in the skin bag was blown in by the mouth, and the oxygen was consumed by the lungs, so the air in the skin bag did not contain much oxygen, Zuo Dengfeng frowned and inhaled all the air in the air bag and abandoned the air bag, he told the big head before entering the water that he was fighting for ten minutes, and half of it had passed at this time.

After the ventilation, Zuo Dengfeng felt cold all over his body, especially his head, which began to tingle under the stimulation of low temperature, and the current situation could no longer allow him to hide his body, and quickly pulled out the yang energy from the pure yang guard to warm up for himself.

A radius of more than two hundred meters, only one-third of the search had been carried out before, and after the ventilation, Zuo Dengfeng accelerated his search, he knew very well that the food prepared by the two would not last long, and Xuanwu would definitely dive to the bottom after the food was exhausted.

No, no, no...... The results of the cutting made Zuo Dengfeng more and more impatient, what he longed for most was to suddenly find a small piece of residual meteorite, as long as he found the meteorite, his trip would be considered complete, and he would be able to leave here immediately, and he was only one step away from saying goodbye to Wu Xinyu. Zuo Dengfeng felt that he was floating between joy and despair at this time, whether he was happy or desperate depends on whether he can find the meteorite, and whether he can find the meteorite depends on luck in addition to his own efforts, and what he dislikes the most is luck, because it is not up to him to decide and control.

Half of it, there is still a third, and there is an area of about ten steps, as the scope of the inspection narrows, Zuo Dengfeng's mood has become contradictory, it is undoubtedly a good thing to be able to check these rocks before the basalt sinks, but as the remaining range is getting smaller and smaller, the hope of finding meteorites is getting slimmer and slimmer.

Just when Zuo Dengfeng's mood was fluctuating, he suddenly found that the water flow had changed, and his body was immediately held up by the current, Zuo Dengfeng's heart suddenly froze, the food ran out, and Xuanwu began to dive.

The speed of Xuanwu's dive is not fast, Zuo Dengfeng eagerly sped up the search speed, but when Xuanwu sinks, the sea water will produce upward buoyancy, and the huge buoyancy makes Zuo Dengfeng's body sway, and he must hold the rock or grasp the bone spur with his left hand to fix the body, so that the speed of one-handed slashing and inspection is slower.

"Calm down! Calm down!! Zuo Dengfeng repeated these two words in his heart, the more critical the moment, the more you must protect your calm, otherwise it is easier to make mistakes in the panic.

Although Zuo Dengfeng has been emphasizing to himself to be calm, it is not easy to really be completely calm, and whoever he is replaced by an ancient giant beast who is brought to the bottom of the sea cannot remain calm.

As the depth of Xuanwu's dive increased, Zuo Dengfeng felt that the water pressure around him was getting bigger and bigger, and after a while, symptoms of tinnitus appeared. He didn't know exactly how deep he was at the moment, but he knew that his situation was already dangerous, and he had to get out of the turtle shell as soon as possible.

But Zuo Dengfeng did not let go immediately, but seized the last bit of time to check the remaining area, hoping to find something at the last moment, because miracles often appear at the last moment.

It's a pity that the miracle did not appear, he did not find the existence of the meteorite among the many rocks, it seems that the meteorite was really completely dug up by Ji Xian and others.

Although his heart was three points cooler than the sea outside, Zuo Dengfeng could only let go, and at this time his eyes had begun to swell and pain, and he had to float.

Zuo Dengfeng let go, he could only let go, he had done his best, at this time he could only pray that the residue left after refining and the material contained in the two huge springs could barely be enough, but he also knew very well in his heart that it was not enough, he had scrutinized and estimated it many times before, it was definitely not enough.

With endless despair, Zuo Dengfeng glanced back at the huge tortoise shell of Xuanwu, and then began to float.

At this time, the huge water pressure has made him unable to float automatically, Zuo Dengfeng can only raise his arms and rush up, but he stopped as soon as his hands were raised, he suddenly remembered that when he turned back before, he found a rock attached to the huge bone spur of the basalt, the rock is very small, and he can't be sure what material it is, but the place where the rock appeared is not right, so small rocks should not appear at the upper end of the huge bone spurs, because the rocks are stuck in the bone spur gaps, and if the rock is very small, it can't be stuck at all, there is only one reasonable explanation, That is, the rock was very large before, so it could get stuck, and later the big rock broke away from the bone spur, and only a small piece was left glued to the bone spur.

The area where Basalt can move after being locked is limited, and the possibility of the rock on its back falling off automatically is extremely small, unless someone takes the rock away!

Thinking of this, Zuo Dengfeng immediately wanted to chase downward, but after bowing his head, he changed his mind and couldn't dive anymore, otherwise he would be crushed to death by the huge water pressure. In a hurry, Zuo Dengfeng rushed upwards with his arm and quickly climbed the back of Xuanwu's head and neck, and Xuanyin True Qi desperately urged.

Zuo Dengfeng's move was purely a deadly fight, if Xuanwu counterattacked, he wouldn't even have a chance to dodge, but at this time, what he wanted was to provoke Xuanwu, maybe Xuanwu would rise again.

However, Xuanwu did not float, Xuanwu was originally a Yin genus, and the Yin Qi in his body was extremely heavy, Zuo Dengfeng's Xuanyin True Qi could not constitute substantial damage to him, and after feeling Zuo Dengfeng's rude behavior, Xuanwu did not fight back, just shook his head and threw him off, and slowly sank to the bottom of the sea.

Zuo Dengfeng failed to strike a blow, and he was extremely frustrated in his heart, but at this time, the breath in his chest was about to run out, and he didn't think much about it in a hurry, and his arms were filled with aura, and he quickly raised his arms and floated up.

As he floated, the water pressure decreased rapidly, and Zuo Dengfeng felt that the pressure dropped sharply, and at this time, a large number of strange fish and giant snakes were still gathered in the area above, and he was inevitably besieged, so he could only change his route halfway and swim towards the alternate exit on the east side.

Although Zuo Dengfeng was very cautious, one of the strange fish that looked like a dolphin still found him, and quickly chased after him from underwater.

People can never be faster than fish under the water, and when the left peak is less than three zhang away from the gap, the strange fish chases after it, the fish mouth is wide open, and the sharp teeth are dense.

Zuo Dengfeng hurriedly turned around and sent out Xuanyin True Qi to condense the sea water into an ice shield to block it, but this move led to extremely serious consequences, although the ice shield blocked the attack of the strange fish, but it could not offset its momentum, under the strong impact of the strange fish, Zuo Dengfeng was quickly pushed away from the gap not far away, and entered the east iceberg.

After pushing Zuo Dengfeng under the iceberg, the strange fish still did not stop, and quickly pushed him to the east, getting farther and farther away from the exit for ventilation. Zuo Dengfeng had nowhere to borrow his strength underwater, and retreated passively, complaining bitterly.

Just when Zuo Dengfeng thought that he was about to be drowned, a huge green shadow suddenly appeared, tearing the strange fish to pieces......
