The carapace of Xuanwu is round, with a length and width of more than 200 meters. Different from the carapace of turtles in the ocean, the carapace of Xuanwu is more similar to that of freshwater tortoises. It is flat in shape. There are many bone spurs on the upper part of the carapace. The length of the bone spurs The thickness varies. Looking at it, it looks like it is carrying a mountain like a stone forest. Xuanwu's limbs are similar to those of reptiles. They are as thick as elephant legs and are seven feet long. The ends of the huge limbs have sharp claws. They are as thick as four children's arms. Black chains locked its limbs respectively. At this time, the four chains were stretched straight, indicating that Xuanwu had risen to the limit of its range of activities. After seeing Xuanwu's tortoise shell, Zuo Dengfeng quickly dived closer and clung to the bone spurs on the top of the tortoise shell to look for it. The tortoise shell covered a large area with different sizes of bone spurs. The longest one could reach more than ten meters. There were a large number of bones attached to the gaps between the bone spurs. There are foreign objects such as earth and rocks. Due to the age, many foreign objects have been adhered to the bone spurs. Because basalt has a large number of bone spurs, when it moves, the bone spurs often scratch the rocks on the seabed, and some of the fallen rocks get stuck in the gaps of its bone spurs. The meteorite may have been scratched by it and stuck in the bone spurs. Rather than falling directly on its back. These rocks are stuck in different positions and at different angles, making it impossible for Zuo Dengfeng to search at a glance. He can only search up and down in the gaps and look left and right. Because the sea water has been polluted and the moss has died, the rocks stuck with bone spurs do not have moss attached to them, but they are covered with shells left after the death of shellfish. The shells cover up the original appearance of the rocks. Zuo Dengfeng did not Knowing what meteorites look like, this situation makes it even more difficult for him to identify meteorites. Meteorites will burn during the fall, and dense holes will be left after burning. This is one way to identify meteorites. However, the rocks contained in the gaps between the bone spurs are covered with shells of different sizes, making it impossible to distinguish them. In addition, according to Datou, meteorites are black, which is another way to identify meteorites. However, most of the rocks and shells exposed under the bone spurs are black, and color cannot be a criterion for identifying meteorites. Zuo Dengfeng quickly filtered through various methods in his mind, and felt that only one method was feasible, which was to use a dagger to cut off various shells attached to the outside of the rock and observe whether there were pores produced by burning the rock. This is the stupidest method, but there is no other way. Since there are many rocks contained in the bone spurs above the turtle shell, Zuo Dengfeng did not dare to hesitate for a moment, and poured his spiritual energy into the dagger to quickly cut the rocks. There are at least hundreds of rocks of different sizes in the area of ??more than 200 meters. It would take a lot of time to check them one by one. Ten minutes is definitely not enough. Zuo Dengfeng couldn't help but become impatient. It's a pity that Datou's instruments cannot be used underwater, otherwise It will save a lot of time. With this in his mind, Zuo Dengfeng suddenly remembered that Datou had used instruments to test this place before Xuanwu surfaced, and found that there was no response. There are two possibilities for this situation. One is that the water is too deep for the instrument to detect the meteorite; the other is that the meteorite is not detected by the instrument. There are very few left, and they are not deep enough to be detected by instruments. Of course, there is a third possibility, that is, there are no meteorites here, but Zuo Dengfeng is unwilling to take this possibility into consideration. Taken together, the second possibility is the most likely. After all, Ji Xian and others once collected meteorites from Xuanwu's back, and there will always be a little bit left. It is impossible to cut them so cleanly. In other words, the meteorites are likely to be Yes, but not big. Thinking of this, Zuo Dengfeng no longer inspected the large rocks, but used his dagger to chop the rocks smaller than the watermelon. Since the inspection scope was reduced, the inspection speed was greatly accelerated. After a while, Zuo Dengfeng made a new discovery. The rocks carried on the back of the basalt were hard in texture and the fragments had sharp edges. This showed that these rocks were basalts that made up the ocean crust. Meteorites fell from high altitudes and would not have edges after being burned. This discovery made Zuo Dengfeng narrow the search scope again, abandoning those small rocks with obvious edges and corners, and focusing on looking for rounder ones. Most of the small rocks were stuck at the roots of the bone spurs, which made the search more difficult. On the way to the top of the mountain, I found that the oxygen in my chest was exhausted. I bit the rubber tube and used the skin bag to ventilate. However, the air in the skin bag was blown in through the mouth, and the oxygen came from Part of the lungs were consumed, so the air in the skin bag did not contain much oxygen. Zuo Dengfeng frowned and sucked in all the air in the air bag and discarded the air bag. Before entering the water, he told Datou that he would try to gain ten minutes. At this time, Half of it has passed. After ventilating, Zuo Dengfeng felt that his whole body was cold, especially his head, which began to sting under the stimulation of low temperature. The current situation no longer allowed him to hide his figure, so he quickly drew out the yang energy from the pure yang guard to warm himself up. . ??????????????????????????????????????????????????????????????????????????????????????????????????????????????.After the food is exhausted, Xuanwu will definitely dive into the water. No, no, no The results of the cutting inspection made Zuo Dengfeng more and more impatient. What he longed for most was to suddenly find a small piece of remaining meteorite. As long as he found the meteorite, his trip would be considered complete and he would be able to leave here immediately. With only one step away from seeing Wu Xinyu again, Zuo Dengfeng felt that he was floating between joy and despair at this time. Whether he was joyful or desperate depended on whether he could find the meteorite, and whether he could find the meteorite would depend on his own efforts. In addition, it also depends on luck. What he dislikes the most is trying luck, because it is beyond his control. Half, there is still a third, and there is still an area of ??about ten steps. As the scope of inspection shrinks, Zuo Dengfeng's mood becomes conflicted. It is undoubtedly a good thing to be able to inspect these rocks before Xuanwu sinks. But as the remaining area becomes smaller and smaller, the hope of discovering meteorites becomes increasingly slim. Just when Zuo Dengfeng was feeling ups and downs, he suddenly noticed a strange movement in the water flow, and his body was immediately lifted up by the water flow. Zuo Dengfeng's heart suddenly shuddered. The food was exhausted, and Xuanwu began to dive. Xuanwu's diving speed was not very fast. Zuo Dengfeng eagerly accelerated his search. However, when Xuanwu sank, the sea water would generate upward buoyancy. The huge buoyancy made Zuo Dengfeng's body sway. He had to use his left hand to hold on to the rock or grab it. The body shape can only be stabilized by holding on to the bone spurs, so that the speed of cutting and checking with one hand will be slower. "Calm down, calm down," Zuo Dengfeng repeated these two words in his heart. The more critical the moment, the more important it is to maintain calmness, otherwise it will be easier to make mistakes in panic. Although Zuo Dengfeng has been stressing to himself that he should calm down, it is not easy to be completely calm. Anyone else would not be able to keep calm even if he was taken to the bottom of the sea by an ancient giant beast. As the depth of Xuanwu's dive increased, Zuo Dengfeng felt that the water pressure around him was getting stronger and stronger. After a while, he developed tinnitus symptoms. He did not know the exact depth he was currently at, but he knew that his situation was already very dangerous. , must break away from Xuanwu's turtle shell and surface in the water as soon as possible. But Zuo Dengfeng did not let go immediately. Instead, he seized the last moment to check the remaining area. He hoped to find something at the last moment, because miracles often appear at the last moment. "It's a pity that the miracle did not happen. He did not find the existence of meteorites among the many rocks. It seems that the meteorites were thoroughly dug out by Ji Xian and others. Although his heart was three times cooler than the sea water outside, Zuo Dengfeng could only let go. At this time, his eyes had begun to swell and hurt, and he had to float up. Zuo Dengfeng let go. He could only let go. He had tried his best. At this time, he could only pray that the remaining residue after refining and the material contained in the two huge springs could be barely enough, but he also felt sad in his heart. It was very clear that it was not enough. He had gone through many deliberations and estimates before, and it was definitely not enough. With endless despair, Zuo Dengfeng looked back at Xuanwu's huge tortoise shell, and then began to float up. At this time, the huge water pressure made it impossible for him to float up automatically. Zuo Dengfeng could only raise his arms and rush forward, but he stopped as soon as he raised his hands. He suddenly remembered that when he turned back earlier, he found a piece of bone attached to the huge Xuanwu bone spur. The rock, the rock is very small, and I can¡¯t be sure what it is made of, but the rock appears in the wrong place. Such a small rock should not appear at the top of the huge bone spur, because the rocks are stuck in the gaps of the bone spurs. The rock is very If it is small, it will not get stuck at all. There is only one reasonable explanation, that is, the rock was very big before, so it could be stuck. Later, the big rock broke away from the bone spur, leaving only a small piece of stick. On the bone spur. After Xuanwu is locked, its area of ??activity is very limited, and the possibility of the rock on its back falling off automatically is extremely small unless someone removes the rock. Thinking of this, Zuo Dengfeng immediately wanted to catch up, but after lowering his head, he changed his mind. He could no longer dive, otherwise he would be squeezed to death by the huge water pressure. In desperation, Zuo Dengfeng rushed up with his arms. , quickly grabbed the back of Xuanwu's head and neck, and Xuanyin's true energy was vigorously activated. Zuo Dengfeng's move was purely a desperate move. If Xuanwu counterattacked, he wouldn't even have a chance to dodge. But at this time, what he wanted to do was to anger Xuanwu, and maybe Xuanwu would rise again. However, Xuanwu did not rise to the surface. Xuanwu is originally a yin attribute, and the yin energy in his body is extremely heavy. Zuo Dengfeng's Xuanyin Qi could not cause substantial harm to him. After feeling Zuo Dengfeng's rude behavior, Xuanwu did not respond. He didn't fight back, just shook his head and shook him off, slowly sinking to the bottom of the sea. Zuo Dengfeng's attack failed, and he was extremely frustrated. However, the breath he was holding in his chest was about to be exhausted. In desperation, he could not think too much. He carried spiritual energy in his arms and quickly raised his arms to float up. While floating up, the water pressure decreased rapidly, and Zuo Dengfeng felt that the pressure dropped sharply. At this time, the area above was still crowded with a large number of strange fish and giant snakes, and he was inevitably under siege.??We can only change the route midway and swim to the backup 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 him from the water. Zuo Dengfeng was in urgent need of ventilation at this moment and had no intention of fighting, so he quickly swam towards the exit. People can never be faster than fish underwater. When Zuodeng Peak was less than three feet away from the gap, the strange fish chased after him with its mouth wide open and sharp teeth densely packed. Zuo Dengfeng hurriedly turned around and sent out Xuanyin Qi to condense the seawater into an ice shield to block it. However, this action led to extremely serious consequences. Although the ice shield blocked the attack of the strange fish, it failed to offset its momentum. Under the powerful impact of the strange fish, Zuo Dengfeng was quickly pushed away from the gap not far away and entered under the iceberg on the east side. After pushing Zuo Dengfeng under the iceberg, the strange fish still didn't stop, and quickly pushed him to the east, getting further and further away from the ventilation outlet. Zuo Dengfeng had no place to rely on under the water, so he retreated passively, complaining. Not enough. Just when Zuo Dengfeng thought he was about to drown, a huge green shadow suddenly appeared and tore the strange fish into pieces
