Lu Chao stiffly carried the skeleton knight and retreated after a few attacks.

After eating the poison sac, Lu Chao put on his armor and returned to the cave.

Tried to use the Thunderbolt against the Skeleton Knight, and it turned out to work.

It's just that the gold coins are very distressed when they burn.

You must know that what is being spent now is Lu Chao's own gold coins.

A few minutes later, Lu Chao took care of the skeleton knight and those skeleton soldiers.

More than two million gold coins were spent!

"Holy! It's not going to work like this, I'm going to go bankrupt soon. Lu Chao frowned.

Fortunately, Dian Wei burst a ring out.

There is an additional skill on the ring: Consumes 20 internal strength, doubles the damage of undead creatures and halves the damage of undead creatures within 2 minutes after casting; Cooldown: None.

After putting on the armor and halving the damage, these undead knights and soldiers no longer pose a threat to Lu Chao.

Lu Chao took the halberd and went all the way to the depths of the cave and killed it.

The terrain inside the cave is very complicated, and there are many forks in the road, so if you are not careful, you will get lost.

The undead creatures in the cave no longer posed any threat to Lu Chao, and rushed in like chopping melons and vegetables all the way.

The hole is very permeable, and there are puddles everywhere, and some of the passages have to be dived under the water to get through.

After the game field of view switches, the various feelings are very real. After diving into the water, you will feel suffocated just like you actually dive in, and the further down you go, the lower the water temperature becomes.

Finally, Lu Chao met a small boss, Xu Chu, who is also one of Cao Cao's generals.

This time, Lu Chao did not open a thunderbolt, but used the terrain to maneuver with Xu Chu, and it took more than half an hour to stab Xu Chu to death with a halberd.

After Xu Chu died, a map was revealed.

It's a map of this cave!

A very complex map.

Fortunately, he got this map, otherwise, without the hint of the map, Lu Chao would not have been able to find the entrance to the secret location at all.

Half an hour later, Lu Chao stopped in front of a dead-end puddle, and after hesitating for a moment, he jumped into the puddle.

The key to the next stage is in this puddle, and after going down, there is a very complex underwater hole, and it is an underwater hole with no way out.

According to the guidance of the map, Lu Chao swam to a cave wall in the middle of the water without any special features, and after trying, his body passed directly through the cave wall.

This Lu Chao is no longer strange, there are many hidden places in the Desperate Wilderness that are designed like this, many players always intentionally or unintentionally squeeze into some rock walls and mountains when fighting monsters in the novice city, hoping to suddenly squeeze into a hidden place that others have not yet discovered, and then find a treasure chest or something.

After passing through the cave wall, it is still a very complicated underwater cave passage, and there are many forks in the road, Lu Chao swam around for a while, and then forced through the cave wall twice, and then swam back to the ground of the cave from another exit.

The number of undead creatures here began to increase, but they were still no match for Lu Chao.

Finally, Lu Chao stood in a place similar to a water curtain.

The ground trembled slightly, as if there was a monster walking on the other side of the water curtain.

It is conceivable that a monster that can make the ground of a cavern shake by walking, at least in terms of size, cannot be taken lightly.

This water curtain was supposed to be the entrance of some kind of dungeon, and after entering the water curtain, Lu Chao bumped into a huge skeleton monster head-on.

It carried a sledgehammer in one hand and a worn metal shield in the other, and when it saw Lu Chao coming. Immediately screamed and rushed this way.

This monster's attack is not high, and it's easy to dodge, but its blood is thick, and it also has a health recovery function, if the output is not fast enough, it is likely to not be able to catch up with its fast blood recovery.

It took Lu Chao nearly an hour to get it done.

After the sledgehammer monster is killed, a strangely shaped key is unearthed.

There is a locked chamber behind the monster, and it looks like the key is used to open it.

After opening the iron door of the secret room, I entered a very round room, which should be said to be a very round underground cavern, and the walls of the cave were very weathered, as if a whirlwind was blowing in it.

When Lu Chao entered the iron gate, the iron gate suddenly closed automatically!

Not only did it close, but it disappeared into the surrounding rock walls as if it had never existed.

Lu Chao looked around, and found that this was a circular secret room, and there was no other way.

Lu Chao reached out and touched the location of the iron gate, but he couldn't touch anything, just the smooth rock wall, which was no different from the surroundings.

There was no way, Lu Chao had to look around and touch everywhere along the rock wall.

Finally he touched a lever and tried to pull it.

The moment he pulled the lever, the ground of the secret room suddenly disappeared, and Lu Chao fell into free fall into the abyss, because he was caught off guard, he almost exclaimed.

At the end of the ground seemed to be a large whirlpool formed by the underground water flow, spinning rapidly to give people a very terrifying feeling, and Lu Chao, who was falling rapidly, did not feel too much, so he fell into the whirlpool.

"What a rashness!" Lu Chao regretted a little that he shouldn't pull the lever.

Fortunately, everything was in danger, and after entering the whirlpool, Lu Chao did not feel suffocated, but his mind was slightly in a trance, and he woke up after a while.

When Lu Chao came to his senses, he found that he was not under the water, but sitting on the cold stone ground.

Looking around, he seemed to have come to a place that resembled the hall of an ancient castle.

Lu Chao checked it and found that the teleportation stone given by Jiang Xiaoyun had turned gray, and he tried it, but it really couldn't be used here.

Lu Chao suspected that the vortex just now was a portal, and teleported him to a far away place from Crescent City, so the teleportation stone lost its effect.

There were no monsters in the empty castle hall, the air was a little clammy and cold, and some very old umbrellas were piled up next to the large iron gate of the castle, and they were covered with dust.

The iron door could not be opened from the inside, and the button on the wall to open the door seemed to be damaged, and when it was pressed, the iron door only creaked, but there was no movement at all.

Through the large iron gate, you can faintly hear the wind and rain outside the castle, and the occasional rumbling thunder.

There are no windows in the hall on the first floor of the castle, so you can't see the scene outside the castle, but there are some torches on the walls that never seem to be extinguished, and the light that is not too bright shines on the ground and stone walls, reflecting everything in a dim yellow.

Evil Spirit Castle?

I wonder if there will be something thrilling waiting for him?

It looks like you'll have to explore the castle first, and you might be able to find a way to open the castle's large iron gates.
