Unexpectedly, the tunnel in front did not collapse and still maintained its original appearance. Only in some places that were severely beaten, a thin layer of the rock surface was cut off. The rocks in other places were basically not damaged, but the surface was covered with a layer of damage. A layer of dark traces. It¡¯s so shocking! The rocks in the corridor are so hard that even so many concentrated attacks cannot break them and collapse. This is incredible! But considering that this is a secret realm in the north, it¡¯s understandable no matter how incredible the things here are. Then everyone looked at the bat monsters and found that the violent explosion just now did not kill all of them, but only about half of them. There were also ** bat monsters at both ends of the corridor. At this time, they retreated far away. He stared at everyone with extremely fierce eyes. Some of them stand on the ground with their wings folded, some grab the wall or ceiling with their claws, and some float in the air with their wings flapped. "Squeak, squeak, squeak!" Suddenly, the bat monsters collectively emitted sound waves, turning into an invisible shock wave, attacking everyone from front to back. "Ah!" This sound wave attack is extremely lethal. Level 9 professionals are not affected much, but the fighting spirit in their bodies surges. The body shakes suddenly and quickly returns to normal, but level 8 great swordsmen are greatly affected. Except for Ruian, the other five level 8 great swordsmen were shaky and temporarily lost their combat effectiveness. One of them, a weaker level 8 great swordsman, collapsed to the ground. Ruian's condition was a little better than other level 8 great swordsmen, but a little worse than a level 9 professional. When sound waves without warning poured into Ruian's ears and impacted Ruian's body. The fighting spirit in Ruian's body suddenly shook violently, and his body was also shaky. But his fighting spirit is relatively strong after all, and he can control it with all his strength. He recovered quickly and regained about 80% of his combat effectiveness in an instant. In this way, the seemingly simple sonic attack of the Bat Warcraft caused everyone to lose nearly half of their combat effectiveness in an instant, leaving only six level 9 professionals and Ruian still with combat effectiveness. Fortunately, everyone just used long-range attacks first and destroyed half of the bat monsters first. Otherwise, if the bat monsters were in their prime state and used sonic attacks, even level 9 professionals might not be spared. After the bat monster issued a sonic attack, it suddenly rushed towards everyone. Judging from the posture, it requires hand-to-hand combat. Obviously this is their fighting method. They attack with sound waves first, stun the enemy, and then go up to fight melee. In the direction in front of everyone, there are three level 9 sword masters blocking the front, so there is no problem at all. But from behind, only Simonster and Ryan were blocking the front. The other level 8 swordsmen who had turned around had all lost their combat effectiveness. Although a level 9 Holy Mage has already turned around to help at this moment, the situation is not optimistic. "I'll block the monsters behind. You kill the monsters in front first." Ruian suddenly shouted. The strategy he chose was very simple. He took advantage of the narrow width of the corridor and the fact that the bat monsters could not fly over at once. He let go of the three bat monsters in front of him and stood in front of the fourth bat monster. He cast the superimposed stone wall magic to block the entire corridor, and all the bat monsters behind him were immediately blocked. "Bang!" The fourth and fifth bat monsters flew too fast. It hit the stone wall, causing numerous cracks in the stone wall. But it didn't break, which shows how powerful Ryan's superimposed magic is. Then the bat monster suddenly stretched out its claws and struck. Only then did the stone wall break. But then they had to face the second stone wall, and then there were the third and fourth walls When the bat monster smashed the seventh stone wall and there was no more stone wall ahead, it had been delayed for nearly ten years. The rest time, such a long time, is enough for Simonster and another level 9 holy magician to kill the three bat monsters in front. Next, Ryan joined the battle, and the three of them easily killed the remaining five bat monsters. At this time, the battle in the front direction also ended, and the three level 9 sword masters more easily killed the bat monsters in front. In this way, the attack of the bat monster ended with the annihilation of the entire army of monsters. The condition of the level 8 great swordsmen who had just been hit by the sound wave was not serious. They sat quietly for a while, adjusted the fighting energy in their bodies, and quickly recovered. During this period, Ryan and several level 9 sword masters worked together to peel off the corpse of the remaining bat monster and dig out the crystal core of the monster. These crystal nuclei are all level 7 magic crystal nuclei, which are not very precious to level 9 professionals, but one crystal core means killing a level 7 monster. The number on the market is very rare, so level 9 professionals We also want these crystal nuclei. In the end, the more than 20 magic crystal cores harvested were shared equally by everyone. The level 9 professionals and Ruian each got two, and the level 8 great swordsman each got one. Everyone has no objection to this, after all, Ruian's contribution is as much as a level 9 professional. Even Vipses, who is very dissatisfied with Ryan, has no objection. Of course, the key reason is that the value of the level 7 magic crystal core is very small. It would be too embarrassing to care about it.It¡¯s over. After a short rest, everyone continued to move forward. In the next corridor, everyone encountered several more attacks from the Bat Warcraft. However, since everyone knew the attack methods of the Bat Warcraft, it was easy to formulate corresponding response strategies, so it was easy to defeat the Bat Warcraft. The exit of the corridor is just ahead, and everyone finally completed the several-mile-long corridor. "Everyone, should we go back to pick up the others?" Ruian asked suddenly, and everyone stopped. Ryan's idea is very simple. His group is the most powerful, so it is easy to deal with the Bat Monster. However, the strength of the latter two groups is weaker. Once they encounter the Bat Monster, they may be damaged. Ryan thought that there were people like Escardi, Elliot and others he knew behind him, and he didn't want them to be killed or injured, so he made this suggestion. Everyone was thinking about this suggestion and seemed to be wondering whether it was worth it. But Vipses was the first to refuse and said coldly: "Ignore them, those bat monsters are not difficult to deal with. If they can't even deal with them, then they don't have to go into the secret realm." Ryan frowned, what Vipses said It makes sense, but the tone of Vipses's answer was that he didn't like Ryan at all, and he was clearly against Ryan. However, Ryan could not deal with Vipseth now and would not fall out with Vipseth easily, so he remained silent. ???????????????????????????????????????? Others agreed with Vipses¡¯ statement, and the team continued to move forward. The exit of the corridor was a light curtain. Everyone came to the light curtain and paused for a moment. ¡°Everyone, get ready for battle and charge forward together.¡± Cheshu Di said softly. It is obvious that this light curtain is like entering another world. If you walk in slowly, you will worry about something unexpected happening. Immediately, everyone took a few steps forward quickly in the same way as before entering the light curtain. After entering the light curtain, they took a few steps forward again. Suddenly, Ruian first felt his eyes light up. His eyes, which had been in fiery red dim light, suddenly saw the light of broad daylight. Secondly, Ruian felt a wave of heat rushing over him, and the surrounding temperature suddenly changed from tens of degrees below zero in the corridor to the normal temperature in the mainland. Finally, Ruian saw that he had left the ice field, as if he had suddenly returned to the mainland, because there was no ice and snow in front of him, and what appeared in front of him were two barren mountains with a long valley in the middle, looking like a wasteland. Everyone was on alert for the first time, but soon discovered that there was no danger nearby. It was really a wasteland with nothing around, not to mention monsters and beasts, not even flowers, trees, and other plants. The two barren mountains in front of me are covered with slightly black rocks. The ground in the valley in the middle is not the usual mud, but has a rocky surface. No one was surprised. The information that everyone knew more or less was recorded in detail about the situation when they just entered the secret realm. The situation in front of them was similar to the situation in the records. "Let's wait here for the people behind to arrive." Cheshudi said softly. No one objected. This was agreed before and everyone acted together. While waiting, Ruian took off his thick robe and returned to his normal attire. He turned back and looked at the light curtain that had just come in. It was small in area and consisted of a faint layer of white light. He couldn't help but sigh in his heart, this light curtain was so magical, it actually connected two different worlds. Suddenly entering another world from the ice field. Later, Ruian was thinking about the world he was in now, wondering if he was still in the original world, but this question was destined to have no answer. Half a day later, the second group of people arrived. Some people were injured, but no one died. Escardi and Elliot, who Ryan is more worried about, are safe and sound, and Reggie, who has a vendetta against Ryan, is also safe and sound. Half a day later, the third group of people arrived. This time they were not so lucky. In addition to some injuries, a level 8 swordsman also died under the claws of a bat monster in the corridor. Regarding this, Ruian couldn't help but sigh again. In the outside world, a level 8 great swordsman can be said to be a powerful figure, but in the secret realm of the north, he is as fragile as an ordinary swordsman and can easily die in various environments. . Everyone rested for a while and quickly got into position and set off. Now we have entered the secret realm, but if we want to gain something in the secret realm, it will take a long time of hard work. If there is something to gain as soon as we enter the secret realm, then it is impossible for everyone to gain something, because there are all the things at the entrance of the secret realm. The valuable things have long been taken away by people who entered the secret realm before. "Let's pass through this valley first." Cheshu Di, who was walking at the front, said loudly. Since this expedition, he has performed very competently as the leader of everyone. The valley is not straight, but curved along the mountains. Everyone walked hundreds of meters, and immediately after turning a corner, they saw an incredible scene. Several level 8 great swordsmen couldn't help but be shocked.Breathe it out. "Pillar of Fire!" (To be continued)
