The sound wave resonance amplification environment deep in the ground cracks is completely a miraculous natural coincidence. No one would have thought that the naturally growing stalagmites would be just above the lava that continuously releases gas. The air flow passes through the holes, whistles, and then resonates back and forth. , forming strange fluctuations that can disturb the mental power of intelligent races. Although it is so magical, it is very simple to destroy such an environment. 20 aerial bombs fell into the abyss of 10,000 meters, just like a few inconspicuous grains of rice. Their destructive power was not particularly great, but it was enough to pose a threat to those stalagmites. ¡°Boom, boom, boom¡¡± As one 100-kilogram-equivalent aerial bomb fell one after another, thick plumes of smoke gradually rose from inside the cracks in the ground. Violent explosions echoed on both sides of the cliffs. Twenty stalagmites were severely damaged, and countless rubbles were blown into the air or fell deeper into the cracks in the ground. The edges of the cracks in the ground trembled slightly, and from time to time, gravel rolled down the slope and fell into the abyss. The bombardment focused on the stalagmites had an immediate effect. After twenty consecutive loud noises dissipated, the strange sound waves that continued to surge like a tide immediately became much weaker. Even without the protection of the giant wind magic shield, the weakest Human and Feather warriors can barely reach the vicinity of the Doubt. "Not enough, continue! Change to 500kg high-explosive aerial bombs, 10 bombs, delayed fuses for 15 seconds!" The effect of the first wave of bombings did not satisfy Lin Mo. He nodded to You again, signaling to try again . "Isn't it too powerful?" Yin Longyou raised his head and looked at the dome that was only 1,200 meters above the ground. An excessively powerful explosion may cause the dome to collapse. Firearms cannot be used as unscrupulously in the underground world as in the surface world. "It doesn't matter, there is still enough height in the crack in the ground. The delayed fuse will allow those stalagmites to offset part of the impact." Playing intrigues, ten Lin Mo's are no match for the Li sisters. When it comes to playing with aerial bombs, a hundred ghosts are no match for Lin Mo alone. For the power of an aerial bomb with an equivalent of 500 kilograms, combined with the terrain within the ground crack, he can completely ensure that the shock wave after the attack will not have an impact on the dome. No one digs their own grave. ?????????????????????? Ten larger aerial bombs were once again placed in front of Yinlong You. He was not in a hurry to throw them because he needed to manually adjust the fuse activation time. Although the mechanical delayer cannot read seconds extremely accurately. But it is enough to control the detonation delay in the range of 5 seconds to 5 minutes. The first 500-kilogram aerial bomb fell from a height of 500 meters to the ground. With its own weight and the kinetic energy of the fall, it crashed into the interlaced stalagmite area and hit a depth of 30 meters. In just ten seconds, Yin Longyou used his sub-phase jumping talent to throw all ten aerial bombs into the cracks in the ground. The countdown of the mechanical setting still had an error of about 0.5 seconds. At 16 seconds, a large piece of shattered stalagmite flew into the air, and a stalagmite crushing area about 100 meters in diameter instantly appeared deep in the ground crack, like a semicircular giant. pit. The explosion did not stop. After ten consecutive loud noises, the bottom of the first blasted stalagmite pit collapsed again. The bottom suddenly collapsed, sinking deeper and deeper, and finally a large bottomless hole appeared. A pungent hot air flow filled with the smell of sulfur surged up from the hollow of the stalagmite bush, making a low whistling sound. I couldn¡¯t help but there were continuous huge earthquakes, followed by the second and the third. The fourth stalagmite pit collapsed one after another, and the same pungent hot air flow came out. Although the other six large pits also collapsed, they did not completely bottom out. After the vibration stopped, the strange sound waves that had become very weak completely disappeared, as if they had never existed. Under the continuous heavy blows of thirty aerial bombs, four large holes were opened in the dense stalagmites, and the gas released by the lava flowed without any hindrance. The natural resonance structure deep in the cracks in the ground was completely destroyed and turned into a big colander. The sound waves that could stir up the fluctuations of mental power became a rootless tree and disappeared naturally. "There is no sound!" Yin Longyou took the initiative to walk out of the protection range of the giant wind spell shield and came to the edge of the ground crack. There was silence all around, except for the low whistling sound of air flowing deep in the cracks in the ground. The reason why I couldn't smell the pungent sulfur smell before was because the large number of stalagmite bushes have countless holes, which can filter and adsorb to a certain extent. Even if some smell successfully penetrates, it will be quickly absorbed by the clean air or growing in the dark. Bacterial purification in the area. "The exit is over there!" Lin Mo pointed forward. Two illumination light ballsIt was hanging at the entrance of a deep cave about 500 meters away from the crack in the ground, a full 15.5 kilometers away from where he was standing. Looking from a distance, it looked like two small adjacent stars. The entire ground crack in front of the team is actually located at the edge of the entire dark zone. As long as you enter the cave entrance and walk for more than ten kilometers, you can enter another area. The cliffs on both sides are about 15 kilometers apart, which is not a problem for the entire team, not even as good as the previous weird sound waves. The giant dragons and the supreme beings of various intelligent races can walk through the air, and there are also five magic square spaceships. Therefore, the gap in the ground looks like a chasm, but in fact it is not an insurmountable obstacle. "The God Seed 'Sachari' really knows how to find a place!" Silver Dragon You seemed to be able to understand why it was only now that the intelligent races in the firmament world really confirmed the existence of the God Seed "Sachari". It was only then that Dragon King Igfisro, who had known this secret for a long time but had concealed it until now, finally made up his mind to eliminate this hidden threat. It is precisely because the opponent's hiding place is so secretive and unbelievable that if the giant dragon clan had not paid such a huge price in the death and serious injury of two generations of the gold dragon clan's clan leader, I am afraid that this god "Sagali" would have been allowed to continue to roam free. . The team that was blocked in front of the crack in the ground and blocked by the strange sound waves did not participate in any battle. They simply threw dozens of bombs and easily solved the problem. It didn¡¯t take much effort to cross the ground crack that was more than ten kilometers wide, nor did it encounter any accidents. The team arrived at the other side of the ground crack without any danger. Although the entrance of the cave is large enough for transport airships to enter, the irregular space inside is a bit narrow. After going two hundred meters deep, it is no longer possible for these large-scale construction aircraft to move forward. All humans and Yu tribes have to walk at the entrance of the cave. , which also included the maids of the communication ship, but they were transferred to armored vehicles loaded with workbenches, a total of twenty. Although the carriage is a little crowded, the dojo in the snail shell, the various functional modules possessed by the communication ship, these specially customized crawler armors also have most of them, but the power and volume are much smaller, but in the cave The inside is just right. The two "Lich Eyes" one after the other turned on the automatic mode and took the lead in drilling deep into the cave. Waves of rhythmic sound waves continued to echo. In a short time, the sonic detection system of "Eye of the Lich" completely scanned the internal environment of this cave and established a three-dimensional model. Even if there are side roads, you will not get lost easily. "That's it, go to the left!" Hitamaiyas, the current leader of the Gold Dragon Clan, stretched out her dragon claws and touched a corner of the cave wall. She nodded hard towards the left hole in the three-way entrance, even if she didn't rely on it. As for the "Eye of the Lich", it can always find the right direction at the first time. Although the giant metal dragons following it could sense that a two-inch-long red copper nail was nailed on the rock wall, they honestly did not dare to make any plans for this little snack. Along the way, there were not a thousand, but at least eight hundred, small red copper nails like this. All the unlucky ones who dared to take advantage of them were beaten up by the patriarch. Hitamayas discovered the red copper nails, and after a very complicated perception, she allowed them to stay in their original positions. There was only one initiator of these red copper nails being placed into the stone wall, and that was Su, the leader of the previous generation of the gold-type dragon clan. He left a precious route for himself and those who came after him (To be continued.) Section 1508 - Entering the cave: Mobile phone users please visit http://m.piaotia.net
