There are various "small caves" in the Giant's Cave Mansion, which are only small compared to the "main hall", but for humans, they are really grandiose.

Xu Zhuo and the others fled to one of the caves, hundreds of meters high, and the rock pillars supported in it had to be hugged by four or five people to hug each other in a circle, and the stone pillars and walls were carved with thick and simple symbols, these symbols emitted black fog, which was not simple.

Catherine was well-informed, and immediately whispered: "This is a long-lost black magic, I can't imagine that in the Giant Clan, a race that is not good at magic, there are actually giants!"

Xu Zhuo and Catherine hid under the stone table and dived into the cave, not in a panic, but Xu Zhuo's clairvoyance and saw another way to escape, which could be rushed out through a side door of the giant's cave. It turns out that on the other side of the mountain, there is a relatively small exit.

Now that the incident happened, the main gate has long been blocked, and the defense is very tight, only the side of the mountain, which may be used less in normal times, and there are no giants to take care of it.

And to get to that back door, you have to go through this cave.

Xu Zhuo and the others peeked at the situation in the cave as they walked. I saw that there was also a giant in this cave, it was a relatively old but quite tall giant, with pale hair and stubble, all knotted, unkempt, dirty, fiddling with bottles and cans on a huge stone platform, there was a rather transparent crystal jar, which flowed with black liquid, emitting a pungent smell, and from time to time sparks and lightning came out, it turned out that this giant was studying black magic.

The giant was very focused, and he didn't look back, so naturally he wouldn't notice Xu Zhuo and his party tiptoeing past him.

"Catherine, what do you think will happen if I knock over that crystal jar of his and let the black liquid spill out?" Xu Zhuo rolled his eyes, had a bad idea, and whispered to Catherine.

Catherine groaned slightly, and said, "It is estimated that it will explode, at least a large amount of black smoke, as well as sparks and thunder are indispensable." I could sense that the black liquid contained an extremely strong violent energy!"

"Since that's the case, let's act! This giant, I'm sorry!" There are chasing soldiers coming from behind, Xu Zhuo doesn't want to be chased like a dog by the giants again, and he also wants to take revenge on those giants, he also senses that this black liquid should be extraordinary, so he naturally acts immediately.

He waved his hand for Catherine and the elf guards to hurry away, and he took the first step, and he urged the flying sword to slash at the crystal jar.

The flying sword is the size of a small dagger (in the eyes of the giants, it is like a third of the embroidery needle, so small that it can be completely ignored), rises in the wind, and quickly turns into the size of the door panel (this can only enter the eyes of the giants, which is comparable to the size of a small dagger in the hands of the giants), "whoosh~", a sword is slashed on the crystal jar that is high above.

Xu Zhuo's sword power is extremely powerful, containing at least 100,000 jin of strength, the crystal jar flew in response, and was split in half with a "click" in the air, and the black liquid inside was scattered and splashed, as if a lake suddenly exploded in mid-air, and the entire cave was full of black liquid.

Although it was only a jar of liquid, for Xu Zhuo and them, it was no problem to swim in it, and the actual amount was very large.

In an instant, the black smoke was filled, and endless fires and thunder and lightning raged in the black smoke, fortunately Catherine and the female elf guards took the first step, otherwise, the end would definitely be very miserable, and Xu Zhuo, in time to leave the sword, Rao is so, was also blown by the violent breath behind him like a small ant in the wind, and involuntarily flew out of the distance. There was also a ferocious thunder on his back, and he felt a faint pain.

Thanks to his strong body, it was not damaged, but his clothes were scorched and tattered.

At this time, the pursuing giant warriors had just rushed into this black magic cave, and they couldn't stop it, and rushed in, and the people in front wanted to stop, but the giants behind rushed over like tanks, and it was inevitable that they would crash into the air, and even cause trampling accidents, everyone yelled, chickens and dogs jumped, and even two giants were angry because they were knocked down by each other and inhaled too much black smoke, and they were furious, slashing each other, and killing each other.

"Damn it, what the hell?!"

"Dead old man, don't fiddle with those weird liquids, you just don't listen, and now you're going to make us miserable!"

"Who is it? who is it? who knocked over my precious black gold divine liquid?" the old giant was furious and a little crazy, covering his eyes and shouting, because the crystal jar had been split just now, and a few drops of black liquid splashed into his eyes, making him almost blind. Besides, that black liquid was the "black gold divine liquid" that he had accumulated after years of research, and it was actually destroyed by someone like this, how could it not make him angry and ashamed?

In this black smoke, the giant warriors all went berserk, some of them were burned by the flames and their hair and beards were gone, and some of them couldn't bear the thunder and lightning, and they were scorched, crispy on the outside and tender on the inside, and they also exuded bursts of meaty fragrance.

Some were annoyed and angry, and accidentally cut off their companions in the venting of their emotions, and after being counterattacked by the companions, the two giants were full of anger and refused to admit defeat, so they fought very savagely.

Angry, chickens flying and dogs jumping, accompanied by chopping and firelight and thunder, the scene was chaotic and unbearable to look at.

Xu Zhuo and Catherine flew away again, and finally, they came to the last cave, less than a kilometer away from the back door exit. It's the only way to the back door.

Although it has always been frequented by giants, there is a rather thin old giant guarding it. This giant was only half the size of an ordinary giant, and it was skinny and skinny, as if a gust of wind could blow it down, but after all, the other party was a giant, and even if it was thin, it was a thin mountain. Xu Zhuo wanted to kill it, but he would never be able to do it for a while. This old giant is very alert and combat-minded, and it is not comparable to the "women and children" in the kitchen.

With the body of this thin old giant, he can get out of the back door by bending over, if he changes to other giants, he has to lie on the ground and crawl out like a dog, if he is a little fatter, he may be stuck, and it is estimated that this is also the reason why other giants are unwilling to enter and exit through this back door.

But for Xu Zhuo and others, even this "dog hole" is still surprisingly big, quite magnificent and broad!

This old giant is also quite peculiar hobby, it is lying around, is fiddling with a lot of bottles and cans, those bottles and cans are not black liquid, but colorful all kinds of light or smoke, there are red, purple, black, white, colorless and other colors, and even several colors mixed together, such as one of the crystal jars, there are seven colors in it, like seven very unique rays of light, intertwined with each other but not dissolving, like a rainbow dazzling.

Maybe it's because there are crystal mines in the vicinity or something, so there are so many crystal jars here, there are hundreds. And all of them are very huge, if they are sold on the earth, these crystal jars alone will be worth a lot of money!

"What are these?" Xu Zhuo muttered, looking at Catherine. They didn't dare to come out, but hid in a crack in a pile of rocks, secretly looking at the old giant. For, the old giant was very alert, and when they first arrived, the old giant seemed to have noticed it, picked up a crystal magnifying glass on the stone table, and looked at the place where they were. Fortunately, Xu Zhuo pulled Catherine and the female elf guards in time to hide in the cracks of the rocks.

Xu Zhuo knows stealth techniques, but he can only use it on himself, and he has not yet been able to make others, especially so many people, invisible at the same time.

This is also because Xu Zhuo's stealth technique was obtained from the hands of the low-level disciples of the Dry Demon Sect, and he is not a very clever one.

"It's a nightmare technique, and I didn't expect the legend to be true. "Catherine, as the princess of the Grass Elves, is really knowledgeable and well-informed.
