"Twenty high-explosive grenades, plus two mortar shells, such a powerful passage collapsed at least thirty meters or more, and we are injured again, and we can't dig through it in a short time!" said the old man.

"Yes, sir, our water and dry food won't last that long, and there's a lot of mandala!" said a private soldier.

"If we knew that we shouldn't have fought with the monsters, just exit the passage and give up! If it catches up, it's a big deal, we blow up the passage and block it, and we won't be trapped here!" the old man sighed.

Jiang Xingchen thought for a while, and said in a deep voice: "This is not a desperate situation, and the collapsed passage is not the only way out!"

"Huh?" the old man and the four private soldiers were stunned for a moment, and asked at the same time, "Do you know that there are other exits?"

"Otherwise, why do you think I would set a trap in the passage!" Jiang Xingchen nodded and analyzed: "Think about the way we came, the two passages are dead ends, and one passage comes in from underwater, if there is no other way out, how much air will there be in this space......? This means that there must be a place for air to enter!"

"Makes sense!" The old man nodded when he heard this, then stood up and said, "Let's search here first, and then go and see the light source, the monster was there before, maybe it is where the treasure is!"

"Don't go, it's more dangerous than monsters!" Jiang Xingchen hurriedly stopped. Previously, he could see clearly through the telescope that the frog had suffered a loss there, and there were blood marks on his body, so he was defeated. Suffice it to say that it is more dangerous there.

I explained it to the old man. The old man and the four private soldiers all looked terrified. A frog is already so difficult that it can defeat all frogs. Wouldn't it be more ferocious, and staying here is still a dead end.

"I don't know what it is. The telescopes can't see clearly, but they don't seem to be detached from the development light source, otherwise the frogs should chase after them when they retreat!"

Jiang Xingchen comforted everyone and said, "Now check the materials and equipment!"

"Sir, there are thirty high-explosive grenades left...... Two mortar shells...... Mandala, white phosphorus, Molotov cocktail, burst arrow...... Food, medicine and water......" Several private soldiers unloaded their large backpacks behind them. reported one by one, more than half of the equipment brought in by the battle with Qingjiao was used.

After listening to this, Jiang Xingchen ordered: "Throw away the mortar parts, it's useless! A plum blossom petal per person can heal quickly!"

The private soldier and the old man were not hypocritical, they quickly took out the plum blossom petals and took them, and sat on the ground to heal their injuries. Jiang Xingchen gave the demon fox more than a dozen reunions in a row. And he himself has skin injuries, and he only needs to run the formation a few times to greatly relieve his physical discomfort.

While the old man was healing, Jiang Xingchen once again operated the formation and first probed the passage that had been blown down.

It's the same as before. The length of the collapse of the passage was more than thirty meters. And under the rock, Jiang Xingchen could obviously detect different substances, which must be frogs.

Feeling that the frog was motionless, Jiang Xingchen exhaled a long breath: "It seems that that guy was really blown up!"

Before the battle, he had also thought about trying to subdue it by gathering vitality. But the other party was too brutal, more ferocious than the poisonous dragon turtle at the beginning, and he didn't dare to try. If you don't get one right, it's over. And the monster is a level 30 demon beast, except for the divine beast, it is a king-like existence. He thinks that the other party will not be tempted by himself. And the most critical point is that the opponent can crack the formation. He feared that gathering energy would be useless to it.

Therefore, he would rather use the most extreme means of hard fighting, rather than use the lure of gathering vitality.

The vitality released by the Material Exploration Array was withdrawn from the passage, and Jiang Xingchen began to probe in several other directions. The vitality released by the formation cannot be spread out in a large area, and can only be carried out in one line, so the progress is not fast.

This space is very large, and it is dark in the distance, as if there are countless monsters hidden, and it makes people's hearts furious. Jiang Xingchen almost transported the formation to the extreme to reach the edge, but he didn't find anything, almost all of them were rock walls.

"Such a large space is definitely not on the island, and even this island is not so big...... That is, here it should be underwater. The passage you entered seems to be facing down all the time!"

Thinking of this, Jiang Xingchen scratched his head again, it's still not right! If it's underwater, where does the air come from......

Jiang Xingchen continued to use the formation to probe while making various guesses in his heart, and in the end, only the position of the light source in front of him remained.

"There is no passage around at all, it seems that it can only be there!" Jiang Xingchen's eyes stared ahead, and he sensed that his vitality stretched out.

A little bit forward, a little closer to the light source, Jiang Xingchen was so nervous that cold sweat oozed from his palms, there was a place where the frogs had to retreat, who knew what it would be?

However, unexpectedly, he encountered no obstacles, and easily approached the light source.

"Huh?" Jiang Xingchen, who was investigating, suddenly let out a low snort, and then his eyes straightened, completely stupid. He sensed something that was more valuable than the Yuan Stone, the Colorful Crystal.

"There is actually such a thing!" Jiang Xingchen was ecstatic, the vitality of the colorful crystal was much more than that of the Yuan Stone, but it was very rare. He had been in this world for eleven years, and he had seen four of them in the Desert Temple. And just now he had a cursory perception, there were tens of thousands of colorful crystals here, divided into dozens of piles.

Taking a deep breath, Jiang Xingchen tried to calm his mood, temporarily let go of the colorful crystal, and continued to explore.

Further ahead are several pillars, more than a meter high, I don't know what they do. Continue to probe backwards, and that is where the light source comes from, a small entrance to the hole.

"Sure enough, there is a passage!" Jiang Xingchen waved his fist excitedly, appearing more and more cautious. Although he couldn't see anything yet, it was here that Qingjiao was defeated and forced to retreat just now.

Carefully sending the vitality into the cave, Jiang Xingchen was immediately shocked into a cold sweat. There are countless demon beasts in the passage, and the specific demon beasts are unknown, but their vitality fluctuations are quite strong, definitely higher than crabs and ribs.

"No wonder even the level 30 monsters have been forced back, countless level 26 and above monsters are fighting to the death, no matter how strong the monster is, it can't bear it...... But what the hell are those things?"

Jiang Xingchen was full of doubts, hesitated slightly, and walked forward gently. He wanted to see the monsters in the cave with his own eyes so that he could come up with a countermeasure. As for the danger, anyway, those demon beasts will not leave the nearby area, once the situation is not right, they will retreat, cultivate to the Yuan Qi Fusion Array, and the speed of their own explosion is faster than that of the old man, so there should be no danger.

Getting closer to the cave where the light source came from, Jiang Xingchen's figure slowly decreased. Fifty meters from the entrance of the cave, he stopped and took out his binoculars to look.

"Plop lala!" As soon as he lay down, Jiang Xingchen heard the sound of wings flapping in his ears, and several white shadows appeared in the sight of the telescope.

"Bat!" Jiang Xingchen was dumbfounded, he really didn't expect that the demon beast that was higher than the level of the rib crab was actually a bat.

However, this bat is completely different from what Jiang Xingchen knows, not in terms of appearance, but in terms of color and body shape. These bats are all white in color, several times larger than ordinary bats, with wings spread out about a meter, and long tusks growing upwards from their beaks.

"No wonder you can't see clearly from a distance, it turns out that it's all white, and of course it's not easy to be spotted under the reflection of the white light emitting from the passage!" Jiang Xingchen muttered to himself.

See, a few bats that flew out landed on the ground, and when they flew up again, they grabbed another white bat in their claws, but it seemed that the one that was caught was only dead.

Jiang Xingchen lifted his body slightly, and when he looked down through the telescope, he saw a layer of white bats on the ground, densely packed with thousands of them.

"These dead bats all died when they fought monsters! I don't know how many were transported in when we fought just now, and this battle bat should have died more than two thousand!" Jiang Xingchen felt his scalp tingle when he thought of this number. There are more than 2,000 demon beasts above level 26, which is definitely a big group in the vast mountains, and level 29 demon beasts will not provoke them. The last time he went into the depths of the vastness, he encountered it.

"How many bats are there in the passage? After so many years of fighting monsters, I don't know how many have died!" Jiang Xingchen exhaled softly and continued to watch.

The bats are very fast, constantly coming and going, and there are fewer and fewer dead bats on the ground, which are gradually cleaned up.

Eventually, a large number of bats flew out, this time to the multicolored crystals, grabbing two pieces each, and flying back to the cave.

At this time, Jiang Xingchen focused his attention on the colorful crystal. I saw that on both sides of the passage there were dozens of huge stone troughs, seven or eight meters high, and the colorful crystals were placed in it, and the lowest part of each stone trough was a layer of colorful crystals.

"Judging from these stone troughs, there must have been a lot of colorful crystals here at the earliest. If they were all full, they would be estimated to be in the millions...... Did the monster fight the white bat in order to snatch the colorful crystal...... Why don't the white bats leave the neighborhood...... The treasure is really behind this passage...... And what about Long Dan......" Jiang Xingchen's thinking changed sharply.

As soon as he thought of the Dragon Pill, Jiang Xingchen searched around, Chongming Ancestor once said that there were still three Dragon Pills in it, and this was the main purpose of their coming.

After searching around, Jiang Xingchen set his eyes on the five pillars, and there were grooves above each pillar, which seemed to be placed for things, but it was empty at the moment.

"Could it be that this is the place where the Long Dan is placed!" Jiang Xingchen secretly said in his heart: "It seems that he was deceived by the Chongming Ancestor, the Long Dan is there, but I am afraid that it has already been taken ......away by them." )
