The reason why the Thunder Bat Cave always exists underground and does not collapse is because of a special "rock wall" inside. Scholars have not yet studied what material this rock wall should belong to. Even if there are real experts who forcefully dig a piece and peel off the whole fragment, it will lose its special effect.

However, as the whole rock wall, it is not only harder than the defense of a shelled holy beast, but also has the ability to repair itself...

Of course, this repair ability is also at its limit. It is just the scratched white marks that Jiang Ruonan had experimented before, and will naturally be repaired instantly. However, if the crack is too large, the repair will be stopped because it exceeds the repair limit.

Without special rock walls, the part that directly contacts the underground soil and rock can be excavated...

If there are two channels that come into contact with earth and rocks, it is naturally possible to connect a channel connecting earth and rocks.

But neither professionals nor abyss bats will do this on purpose. There is no reason for professionals to help the abyss bats expand their living space, and bats... do not have the instinct to dig holes!

If there are burrow-like abyss creatures, they might do this, but because of their exclusivity, there are no abyss species outside the abyss bats in the cave.

Therefore, there are only some unexpected landslides that will connect the two channels...

Guan Liyuan and others encountered this situation unexpectedly - although the second group of bats that were originally induced was not far from the open area in terms of absolute distance, it would take at least two hours to follow the passage.

However, a collapsed connection occurred in the middle, connecting the two staggered channels, causing the bat group to come back early, and at this time, the "green-haired honest bat" became crazy...

Guan Liyuan and the other five people decided to retreat immediately! If they don’t retreat, they will probably put themselves here...

At the same time, except for Zhong Li Qiu, who was very enthusiastic, the other four people also had a subtle sense of doubt in their hearts. First, they didn’t look like a boss who was “crazy” at all, but they actually became crazy unexpectedly. Then, there were few collapsed modes in a year, and they also encountered it in a way that was most unfavorable to them!

If it is all coincidences, Guan Liyuan felt that it was necessary to find Old Man Tan after he went back - he had a service to exorcise evil spirits.

If it wasn't a coincidence, then... now there is no time for a few people to think too much, so it's important to run away first!

"Go to the entrance of P9 and walk towards the direction of Q3." Guan Liyuan said.

"Well? Is that too 'span' over there? Or is it n7..." Gu Yuanxi questioned.

"Listen to me! I have an idea!" Guan Liyuan didn't have time to explain carefully.

When Gu Yuanxi heard this, he didn't hesitate too much and chose to trust Guan Liyuan's "Ideas".

The situation suddenly became worse. The professional team, which was originally the main attack, turned into a dog that was beaten to the water. Zhongliqiu's "Tiger's Roaring Cloud" also transformed from dividing the battlefield to "covering retreat".

In order to save the "professional power", Guan Liyuan has removed the "Nine-tailed Saint Clothes" and fought with the Dingchun Equinox. At the same time, he summoned three rumble rocks, rolled around and used the "Big Bang" - to clear the retreat road for everyone and win time for retreat.

Before, Guan Liyuan and others tried their best to avoid fighting the bat group in the narrow passage and specially led the boss to a wide area to fight. But now, the few people wanted to come out of the ground and let them drill - because before, it was for the purpose of eliminating the boss, but now it was for the purpose of delaying the retreat as much as possible!

The path suggested by Gu Yuanxi was extremely narrow and there was no need to worry about being taken away from the back.

Although Guan Liyuan chose this road, it is not a big road, but it is also wider...

After retreating from the open area to the entrance of P9 Road, Guan Liyuan summoned the big steel snake and the earthen turtle again to delay time here. There was no need to block the entrance on the other side at this time.

After entering the Q3 path, Guan Liyuan waved his hand to summon three kings of the mountain, including the one he originally trained, which has now reached the lord level, and the other two are commander level.

At this time, abyss bats had already broken through and chased after him. Guan Liyuan simply removed the summoning of the earth turtle and the big steel snake - the profession power of the "Summoner of Another World" was very precious at this time!

The three Chuanshan Kings did not join the battle, but after appearing, they "rolled" backward one step earlier than Guan Liyuan and others...

On the contrary, Guan Liyuan and the five others, including Chongming and Dingchun, joined forces to retreat while delaying the pursuit of the bat group.

Therefore, the three Chuanshan Kings who retreated with all their might soon disappeared.

At this time, Guan Liyuan and the other two could only attack the abyss bat in front of them. There was no sign of the crazy green-haired honest bat, but at this time they did not aim to defeat each other...

"This electrotherapy has become more difficult!" Gu Yuanxi also began to learn Guan Liyuan's words.

"Indeed, the healing ability has not been weakened, and it also has a crazy effect..." He Xigui seemed to have a headache when he heard the tone.

Half an hour later, Guan Liyuan summoned the other three tailed beasts over. At this time, it was meaningless to lead another group of bats further away.

"Here!" Guan Liyuan took the lead in saying at a fork in the road.

"What? This is a dead end, are you right?" Gu Yuanxi exclaimed.

"Don't worry..." Guan Liyuan said.

And Zhongliqiu and Jiang Ruonan had already vaguely guessed what Guan Liyuan's plan was!

The five people followed Guan Liyuan's guide and retreated into a dead end without numbers...

"Yeah? This is..." Gu Yuanxi and He Xigui's eyes lit up at this time.

I saw that in a place that should be a dead end, it was not a dead end, but a small cave...

That's right, although this is a dead end, the blocking road is not a special rock wall, but ordinary earth and rock. The special rock wall is directly cut off here.

Therefore, the three Pierce Kings before could use "dig holes" here, and the reason why Guan Liyuan bought time for them before was to make them "tailor-made" a "trench" that is easy to defend and difficult to attack!

Although Gu Yuanxi and He Xigui first saw the ability of Chuanshan King, they also understood Guan Liyuan's intentions and immediately cooperated to retreat into the "trenches"...

Five tailed beasts are in charge of the palace behind the temple - they will not really die anyway.

Guan Liyuan no longer has the extra power of the "Summoner of Another World" profession, which is used to summon other rumble rocks again. The remaining profession power is also used to maintain the three Piercing Mountain Kings!

After the Rhino Dog and Youlu were defeated and incarnated, the group successfully retreated into the "trenches"...

The entire "trench" seemed to be about to dig a gourd shape. After everyone retreated into the gourd mouth, they found that the inside was very spacious, which was conducive to the performance of the people inside. At the same time, the entrance was narrow. As long as the entrance was blocked, the attacking bat group outside could not exert its numerical advantage.

Although the opponent's abyss demon bats were all stimulated by electrotherapy and entered a quasi-crazy state, they could not attack for a while.
