Hugo was obviously fine just now, but when he squinted his eyes slightly, and when he opened his eyes again, his breath was a little weaker, and You Yuan looked at his blood bar, which was a little less, not as exaggerated as last time, but now You Yuan seemed to have found the reason for his "illness".

"Could it be that some forbidden law was used?" You Yuan secretly guessed in his heart. But now is not the time to talk about it, and if you have the chance, you still have to ask clearly.

You Yuan agrees to Hugo's proposal, but someone needs to stay in the territory to answer and prevent accidents. When Ryan heard this, he immediately jumped out and said that he was going too, and You Yuan thought for a while: "Ursula stay!" ”

Ursula was a good talker most of the time, and she wasn't overly curious like Rey, and she nodded in response to Youyuan's order, "Okay, you guys have to be careful, too!" ”

The three of them left the territory and walked towards the entrance of the underground cavern.

You Yuan had already sensed it very clearly, and now the target was very clear, and the arrow tower was still firing at a fixed frequency at a fixed frequency, and the arrows flew over the heads of the three people. Ryan took the Flame Knife in his hand and lit the flame. Hugo was as calm as ever, and he didn't even take his staff out.

After walking more than 100 meters, through the thin mist, Hugo first saw the appearance of the "cave creature", "It turned out to be such a thing!" There was a slight disdain in his tone, You Yuan could sense the existence of creatures in front of him, and under the attack of the arrow tower in the distance, the aura withered little by little, and finally disappeared, and then it would reappear, and so on.

After walking for more than ten meters, You Yuan also saw the appearance of the thing clearly, and then Rye. By the time the thing was fully exposed to the three of them, the hole was almost piled up with a mass of limp corpses.

[Ooze Monster, Level 18.] The system message prompts, of course, only for the one that just came out, and soon it becomes a corpse.

The three of them stopped more than ten meters in front of the entrance of the cave, watching a soft mud monster push the corpse blocked at the entrance of the cave to the side, and then came out slowly, but before they could take two steps, they were pierced by a heavy arrow from a distance, and three seconds later, it was another arrow, and the blood bar was directly cleared.

After that, there was a quiet pause of six or seven seconds, and then the process was repeated. After watching a few rounds, the three of them found nothing new and decided to go forward and find out.

When the three of them arrived at the entrance of the cave, they just in time for a soft mud monster to come out, and they didn't bother with the arrow tower, but Ryan struck first, taking advantage of his unpreparedness, and finished it with a single sword.

You Yuan decomposes the corpses in one place so that he can see the whole cave. He was very strange, this place was not hidden, the people were still walking back and forth here before the rain, why did such a big hole suddenly appear now?

After decomposing the corpse, he got a bunch of ordinary equipment, some of which were still damaged, You Yuan took advantage of the gap where the three of them were standing here, directly opened the sales interface of the unified shopping mall, and put all the damaged equipment into the box, and finally called 33 copper, and finally couldn't fit it in the storage bag, so he handed it to Ruiyi and asked her to keep it temporarily. Last time she said she had an oversized storage bag that her father had made for her.

Although these equipment are not a good thing, You Yuan thought that in case it would come in handy, it would cost a lot of money if he bought it now, but if there was a place, he would put it first, and then he would be sure that it would be useless.

There is still a bit of a gap between Rey's current level and the other three, and now that he has such a good opportunity to level up, he will stand there and not move, basically killing one or two with one or two swords. You Yuan originally wanted to find a way to test how deep this cave was, but seeing that Rui Yi was slashing hard, he didn't stop, planning to let her cut first.

Hugo took advantage of the gap when no monsters came out of the cave entrance, and cast a ghost fire, and his palm always maintained the control and sensing of the ghost fire in the direction of the cave entrance.

After a minute or so, the ghost fire was exhausted, and he stopped.

"It's a zigzag passage inside, there should be a lot of monsters, my ghost fire can kill 7-8 monsters at a time to deal with monsters of this level, but the strange thing is that after killing these monsters, the ghost fire only walked out less than ten meters, and it was exhausted."

Not a single monster came out within two minutes of Hugo's ghost fire coming out, and Ryan was a little unhappy: "Is there anything else?" Did you kill all the ooze monsters? Is there any of it......"

It wasn't until another monster came out that she stopped talking and began to concentrate on cutting monsters again. But You Yuan noticed that although the monsters that came out this time looked about the same as before, they had become level 19, and he observed two more, yes, they were upgraded.

"Well, Rey, did you notice that the monsters that came out this time were a little higher?"

Ryan just put away the knife: "Huh? Have it? Well, it seems that there is a point, these three did not die with a knife just now, and they had to make up for the knife before they died. ”

In order to allow Ryan to level up, You Yuan had already closed the model worker arrow tower in the system. Hugo and You Yuan both frowned and observed the nearby terrain, and You Yuan occasionally released his mental power to try to sense the fluctuations of the elements in the vicinity.

"Now it's pretty certain that this leads to the center of the territory, the same place I just mentioned." You Yuan said.

Hugo hesitated when he heard this, and finally frowned slightly, ready to close his eyes, but this subtle movement was still discovered by You Yuan, who immediately reached out and grabbed his shoulder: "Hugo......" He didn't say anything about the following words, but shook his head imperceptibly.

Hugo looked at each other in some surprise and didn't speak, but finally stopped what he had just done.

Another twenty minutes have passed, and Ryan has already risen one level, and You Yuan turned his head to look at the monster at the exit, level 20?

What's going on? Even if Ryan upgrades, why do monsters also level up? Is it a coincidence or a system setting? You Yuan was a little confused, but Ryan didn't seem to feel it, and he still happily slashed the monster.

You Yuan turned around and said to Hugo: "The monsters that came out of the cave are upgrading, and they have been upgraded by two levels since we came out!" ”

Hugo understood the meaning of the upgrade, and was a little surprised when he heard this, "Could it be that the monsters determine the order of the hole according to the order of strength and weakness?" ”

"It's also possible! But I ......" Before You Yuan's words were finished, he heard Ryan behind him suddenly "oops", and the two turned back at the same time:

Originally, it would take nearly six or seven seconds for a monster to come out of the hole, but now the monsters are coming out one by one, and the density is still increasing, and there are even two of them crowded into the hole at the same time.

And You Yuan used the system to identify it, and the monsters that came out now are already level 20 and 21.

"Oops, run, run!" Ryan shouted anxiously as she slashed monsters from behind.

You Yuan and Hugo immediately entered the battle, but as there were more and more monsters, the hole was getting bigger and bigger, and the monsters that came out were too many to count, and some monsters were casting poison gas, and Ryan was hit by the monster and retreated several meters, and his leg was already injured.

"Retreat! Back to the territory. You Yuan shouted, and the other two immediately responded when they heard this, You Yuan and Hugo's positions were next to each other, and You Yuan directly fired a fire rain technique to repel the monsters around him, but Ryan was separated by a large number of monsters in another area, just in the opposite direction of the territory, and the distance was getting farther and farther away.
