Thinking back to the battle just now, the elf fat man could see that Wu Yu was indeed a mentor-level magic swordsman, but that kid relied on his superb swordsmanship and skillful magic, as well as his ever-changing weird short sword, the combination of the three showed combat strength far beyond other professions with the same mentor-level title.

"Perhaps, my previous opinion of the Holy Demon Swordsman profession was wrong......"

The elf fat man was thoughtful.

The ruins of the alchemy laboratory of the great alchemy master of the ancient era were not far away, and considering the unknown dangers he might face, Darren decided to rest the night on the leeward rock face below the mountain and climb the mountain again tomorrow.

In the evening, they had a meal of roast tiger meat, and it was Darren who was the cook, although the meat of the Ice Tiger tasted a little strange, but it was not bad, and it had a different flavor. The trouble is that after throwing the raw meat to the sled dogs, they won't eat it. The power of the tiger can be so great even if it is dead. In the end, Darren had to roast and smoke the tiger meat to remove the flavor before the sled dogs could barely eat it.

This night, thinking of the alchemy codex of the alchemy master that might exist, the elf fat man lost sleep. The next morning, he was the first to get up, urging Darren to hurry up and get on their way.

As the terrain gets higher and higher, the snow in the ground gets thicker and thicker, but fortunately, the place to go is not at the top of the mountain, and the sled can still go up. Darren was prescient, with many dogs and great strength, and the 24 sled dogs made full use of their numerical advantage.

The rugged slope on the mountain is not easier to walk than the bottom of the mountain, and the sleigh car is bumpy all the way, and Wu Yu feels dizzy. Compared to the three people who suffered on the sleigh, Tsubaki was much more relaxed, and the White Deer King was worthy of being a super monster mount, holding Tsubaki to jump between the rocks, fast and steady, and very elegant. The elf fat man looked at the White Deer King and was indignant: Why didn't he let his mount ride it? Is this still your own mount?

The elf fat man has a good memory, he still remembers the road after not coming here for more than 50 years, but the snow on the mountain is not static, how many years have passed, the landform has also changed, so the team stops from time to time, and the elf fat man needs to be carefully identified and judged.

After crossing a mountain beam, the scenery suddenly opens up, which is a clearing of about 300 square meters, and the terrain is slightly flat.

"We're here."

"Arrived? There are no caves here, huh? Mr. Euromi, you're not going to go the wrong way, are you? ”

Darren remembered that the elf fat man had said that the fat man had first discovered a cave and activated the magic teleportation array in it before entering the ruins of the alchemy laboratory, but there was no cave or magic teleportation array here.

The elf fat man pointed to the sled dog and the sled cart.

"You'll find out later, let's settle the puppies first, I don't want to walk when I go back."

The elf fat man took out a green staff, lightly touched the ground, a small sapling came out of the soil, and grew rapidly, one by one the branches were intertwined, and finally under the control of the elf fat man, the small sapling grew into a simple wooden house.

Darren was stunned, he tried to open the door of the cabin, but it was still moving. Shocked at the same time, Darren raised his bewilderment.

"Uh...... Mr. Euromi, you are so good at building houses, so why do we all live in tents all this way? ”

"No reason, you didn't let me cover it."

“……”

"Don't be in a daze, hurry up, it's cold and windy on this mountain, don't freeze to death these cute dogs."

Wu Yu and Darren took action, first leading the sled dog into the wooden house, then moving the last items on the sled cart into it, and finally tying the sled cart to the wooden house. Darren was muttering quietly when he was doing things, Wu Yu listened curiously and listened carefully, but this guy complained that the elf fat man built a house and didn't give it to people to live in, but only built a kennel!

Everything was ready, the elf fat man led a few people to a rock wall on the inner side of the clearing, and in the surprised eyes of Wu Yu and Darren, he raised his feet and strode forward, and the fat man disappeared through the rock wall like this.

"It's a psychedelic enchantment, but the cave is right in front of us."

Tsubaki next to her explained with a smile.

"Psychedelic enchantment?"

Wu Yu felt very strange, he had read the psychedelic enchantment from miscellaneous books, so he also knew about this thing. It belongs to the rune array, and the enchantment arranged can form a false scene and cover the contents inside.

The book says that the layer of enchantment of the psychedelic enchantment cannot be touched with his hands like nothing, and Wu Yu is curious and reaches out to try it. His hand passed through like this, but it seemed that the touch was not the same as what was written in the book, because Wu Yu seemed to have touched a soft thing, and he pinched it and felt quite elastic......

"Who's messing around? That's my belly! ”

The voice of the elf fat man frightened Wu Yu and quickly retracted his hand.

Several people passed through the psychedelic barrier, and sure enough, they entered a cave. The cave is not big, and the magical light on the elven fat man's staff has illuminated the entire cave, and you can see that there is a very delicate platform inside. The platform is circular in shape with intricate patterns carved into it, with a stone pillar at each of the four corners, each with a transparent crystal ball at the top.

"This is the Magic Teleportation Array."

The elf fat man briefly introduced the use of the magic teleportation array: as long as a little magic power is injected into one of the four crystal balls, the magic teleportation array can be activated, and it can also be used with fighting energy, and after 10 seconds, it can be teleported to the ruins of the alchemy laboratory. However, this teleportation array is too old, and it may take a little longer.

Wu Yu showed an extremely strong interest in the magic teleportation array, and he touched it everywhere, almost touching it all over again. This is not because of how curious he is about the magic teleportation array, but because the magic teleportation array is also a kind of spatial magic, and his study of this magic teleportation array can be of great help to his spatial magic perception.

Four people and a deer stood on the magic teleportation array, and the elf fat man injected magic power. The magic teleportation array lit up, and standing inside, Wu Yu could feel the excitement of the surrounding spatial elements. Although Wu Yu didn't know what level of his spatial elemental affinity was, because there were no magic props that specifically tested the spatial affinity, it shouldn't be low, at least among the 9 series elements he felt, the spatial element was the strongest.

An invisible shield shrouded the platform, giving people the feeling of a large glass jar upside down, and the scene outside suddenly blurred, and then there was a whirlwind of the sky, and the outside scenery immediately changed, and at this time they had left the small cave and were in the underground palace.

It was pitch black all around, except for the magical glow of the Elven Fat Man's Staff illuminating a small area, and some oddly styled dilapidated buildings could be faintly seen. It's a lot of space and it's icy too.

"There's a torch stuck in the wall, which I left the last time I came in."

Several people lit all the torches, and the outline of the underground palace was fully revealed. A cave with a lot of space, and I don't know how it was dug in the first place. Lots and lots of buildings, with strange symbols and patterns carved on the walls. Under the light of the torches, Wu Yu and Darren were surprised to find 8 decomposing corpses lying on the ground not far away, and 3 corpses were still stuck with feather arrows.

"What is this?"

Wu Yu's foot kicked one of the corpses, it looked a little disgusting, like some kind of beast, but it was very different from ordinary beasts, its feet were like spider's feet, and there were four pairs of eyes, its head looked like a wolf, its body had rotted into bones, and its tail was like a mouse, hairless, wrinkled, and it was a monster. These corpses all look different and strange.

"These are all alchemy beasts, and they use alchemy to combine several magical beasts into one. However, looking at these alchemy beasts, they should all be failures in the experiment. When my daughter Tsubaki and I stumbled upon this place, when we first came in here, we were attacked by them, and most of their strength was at the rank of sergeant, and two of them were close to the strength of the mentor level. ”

The elf fat man led everyone to a closed stone gate, this stone gate was very large, 5 meters wide and 10 meters high, Darren knocked on his small shield, the voice was dull, it should be very thick.

There was obviously something behind the stone door, and the soft sound of Darren knocking on the stone door woke them up, and there was a faint whisper of the beast, it should be the same as the corpse outside, some alchemy beasts, but there seemed to be a lot of them.

"This door should be the inner hall, but I couldn't open this stone door even after racking my brains, so the last time I came here, I only explored the outer hall and then left here helplessly. But this time it's different, with you here, your 'flash' can help us enter the inner sanctum! ”

"Mr. Euromi, my 'teleportation' needs a spatial marker, how do I get in?"

The elven fat man pointed to a row of small squares 10 meters high in the stone door.

"Get the space marker through those vents."

Wu Yu gathered his fighting spirit and jumped up lightly with his legs, he grabbed the edge of the vent and stuck his head up to observe. This ventilation is indeed connected to the inner hall, but the outside is very large, but the inside is very narrow and long, the diameter is only about 5 centimeters, and the length is ten meters, it is a little difficult to throw the dagger engraved with the space mark, but Wu Yu thinks that the elf fat man should be prepared.

After Wu Yu came down, he told the above situation, and the elf fat man really didn't have a surprised expression, he gestured to Tsubaki, who took out a feather arrow from the space pocket. This feather arrow is not placed in the quiver on the back, it is obvious that this feather arrow is special, first of all, this feather arrow is very thin, and it is also short, and the arrow is made of a special metal, which does not repel magic.

Tsubaki smiled indifferently and explained: "This is an enchanted arrow, which is considered a level 0 weapon, you can engrave the space mark on it, and then I will shoot the arrow into it."

Wu Yu had an embarrassed and surprised expression: "Mr. Euromi, is this your plan?" This arrow is too small for me to carve a space marker! ”

The elf fat man's lips subconsciously squirmed twice, and he looked at Wu Yu blankly.

"Ahh What? Do you have any requirements for the size of the object in the space markings you engrave? Then why haven't you ever said anything like this? ”

Looking at the extremely lost appearance of the elf fat man, Wu Yu was very satisfied, hey, he finally repaid the revenge of the terrifying magic potion before.

"Ha, actually, I'm kidding, I can carve ...... Ah, don't pull me by the hair! I see that the atmosphere is a little serious and depressing, just kidding to ease up......"
