This harvest made Xiao Yumei smile and feel much better, humming songs all the way.

Although Xiao Yu had been to the Psychic Academy many times before, he sometimes had a headache about the roads in the Psychic Academy, which was too complicated.

After earning for a long time, Xiao Yu still hasn't been able to find other effective things, and Xiao Yu has the opportunity to take people back.

Although he didn't know what the situation was at the entrance now, Xiao Yu believed that Miranda must have sent someone to guard there, and if he went back, there would definitely be a big battle.

It's just that Xiao Yu thinks that there should be other exits in this psychic academy.

At this moment, the goblin suddenly looked at a place and shouted sharply, "Master, there is something strange here. ”

To be honest, Xiao Yu is very unaccustomed to hearing the sharp voice of the goblin, and every time it is a stinging ear thief. But these guys are really useful.

Hearing this, Xiao Yu's eyes immediately flashed with a hint of essence, and said, "What's weird? ”

The goblin immediately ran up and said, "There is something wrong with the structure here, it looks like it is completely consistent, but if you look at its material, this side is pyroxene rock, and this side is obviously cast iron, and here, it is another kind of rock, and it is definitely not like this when building walls, unless there is a special structure in it." ”

Goblins use their expertise to carry out the analysis.

Xiao Yu didn't know anything about these rocks, and in his opinion, this wall was not a problem at all, but in the eyes of experts, he could see that it was strange.

"Don't talk nonsense, just talk about how to open it." Xiao Yu still likes to do things more directly.

"I don't know." The goblin spread his hands and said very innocently.

"Damn, you don't know what your name is?" Xiao Yu suddenly rolled his eyes.

"This ...... I don't know how to open it, but I know there's something weird here, so let me look into it first, and if it doesn't work, we can try to force it through. The goblin was afraid that his master would be angry, so he hurriedly said.

Xiao Yu waved his hand and said, "Let's go and study." If the research fails, it will be smashed open. ”

"Master, this kind of place is generally very hard, not so easy to smash open." The goblins continued to make noise.

"Then you'd better figure out how to open it, or I'll use your head as a hammer to smash it, and I'm sure I'll be able to break it." Xiao Yu said viciously.

When the goblin heard Xiao Yu say this, he immediately trembled with fright, and then walked to the wall step by step and began to study it cautiously.

The guts of the goblins are still so small.

Xiao Yu laughed, took out a chair, and continued to drink leisurely.

The goblin has been studying for two hours, Xiao Yu has finished dinner there, he still hasn't researched anything famous, he is afraid that Xiao Yu will really use his head to smash the wall, so he is sweating profusely, and his face is extremely ugly.

Xiao Yu looked at it, waved his hand directly at the goblin, and said, "Dodge, just smash me." ”

"This ...... Master...... Give me another chance, I'll be able to ......" The goblin immediately pleaded with Xiao Yu.

Xiao Yu gave Lao Niu a look. Lao Niu saw Xiao Yu's eyes, didn't say anything, directly picked up the big axe, slammed it, and smashed it on this wall.

Thundered......

A puff of smoke and dust poured up, and in front of everyone, a long passage flashed.

"I wiped it, didn't you say it's hard to smash open? How did it open all of a sudden. Xiao Yu was also ready to let Xiaolong go on next, but he didn't expect it to open in a flash.

"This ...... This one...... Shouldn't it be like this? The goblin stood there, staring at the wall that had completely collapsed, his eyes wide in disbelief.

"Whatever, it's open anyway, so let's go." Xiao Yu waved his hand and led everyone and began to walk forward. Xiao Yu wasn't worried about anything dangerous in front of him, the Dark Temple had broken through, could it be even more powerful than the Dark Temple?

Everyone walked along the passage, it was pitch black inside, there was no light at all, but everyone didn't care very much, just take out some gems, or use some magic as light, it was easy to move forward inside.

In this way, everyone has been zigzag forward for more than half an hour, and when they reach the intersection in front of them, it is getting narrower and narrower, and it can only accommodate a few people to pass together.

"There's no road ahead." Mavi and Cassel, who were in charge of pathfinding in front, said.

Although Cassel is not a scout for pathfinding, because he is a shield battle, in order to prevent something from popping up in front of him, Cassel still stands at the front.

His Aesinos ramparts can basically withstand any sudden attack.

"Goblin, go again this time, and if you can't find the exit, keep smashing your head." Xiao Yu said to the goblin again.

The goblin shuddered and swooped over. Reaching the top of the passage ahead, the goblins began to search carefully.

"This was originally a door, but it was blocked for too long, and then it was obviously blocked by something in the back, there is no mechanism here, it just needs to be dug out slowly." The goblin made a judgment this time.

"Dig." Xiao Yu didn't say anything, just one word.

So, a bunch of strong soldiers brought out some guys suitable for work, and began to beat, dig, and prepare to dig out from here. This time, the goblin's judgment was not wrong, on the surface, there was a huge door, but the age of this door was too old, it had decayed inside, and it was fused with the soil layer, and there was no way to open it, so it could only be dug up.

After digging the gate, there is a layer of soil behind it, and there is a lot of messy stuff piled up, and occasionally a few bottles and cans can be dug up.

"Damn, can this be dug out? How deep does this have to be? Xiao Yu watched them dig for a long time without any results, so he asked.

"Surely, master, you see that these dug up things are obviously used by humans, since this is the case, then it means that it should be artificially dumped garbage. Therefore, this is not an innate soil layer, so as long as you keep digging, you will definitely be able to dig out, and looking at the color of the soil, it should not be deep for more than five hundred years. The goblin said as he surveyed the excavated soil.

"Damn, five hundred years?" Xiao Yu jumped up suddenly, the five-hundred-year-old soil layer is not shallow.

"Well, five hundred years, even if there is a lot of accumulation in these five hundred years, it will definitely be able to be dug up, and besides, this is not a hard rock layer, so you won't encounter the kind of place that can't be dug up." The goblin said confidently.

However, as soon as he finished speaking, he heard a clanging sound, and the crowd's digging touched the hard rock.

"Uh......" The goblin was dumbfounded, Xiao Yu wouldn't really smash his head this time. Is this god going to play with him or something, just said that the wall is difficult to open, but it was blasted open by an axe from the old cow, and now it is said that there will definitely be no rock layers here, and it immediately hit the rocks.

Xiao Yu rolled his eyes at this time and said, "What do you say about this?" ”

"This ...... This one...... I ...... the host If I look at it again, it shouldn't be, there shouldn't be a rock layer on it. Unless there has been a huge earthquake here. The goblin's head was covered with sweat, and then he swished over to investigate, for fear that Xiao Yu would use his head as a hammer.

After a while, the goblin suddenly cheered loudly, and said, "Aha, my master, this is not a rock layer, but a man-made rock building, and this is most likely the wall of McGonagall City or something, as long as we dig some more from here, we will definitely be able to dig it out, maybe we can dig into the inside of McGonagall City." ”

"You mean, this is the foundation?" Hearing the goblin say this, Xiao Yu also came over a little suddenly, indeed, this place is not very far from McGonagall City, and it is not uncommon to extend to McGonagall City.

"Yes, I can be sure, you see, these are very regular strips of stone, and they are polished, apparently the stone used for the foundation, not the natural rock layer." Now, the goblin is finally relieved, and his head will definitely not be used as a hammer by Xiao Yu.

"I see, then keep digging for me, remember, dig lightly, don't alarm them, this time, let's give them a center to bloom." Xiao Yu had an evil smile on his face.

I didn't expect this unexpected joy, if this place can really lead to McGonagall City, then Xiao Yu can be very lively inside, like Xiao Zhantian back then, completely occupy McGonagall City, and write a brilliant chapter.

As for provoking a war between the two countries, the war is about to start anyway, so let's provoke it, here is 108,000 miles away from Xiao Yu's Lion King Territory, and the Lance Empire will definitely not be able to fight it for the time being.

And there are other lords here, the principality is going to worry about it, what is Xiao Yu afraid of.

So, a group of soldiers slowly excavated these rocks, Xiao Yu asked Kael'thas to burn the rocks with fire first, burn the rocks, and then pour water on them, through the principle of re-expansion and cold contraction, make the rocks brittle, and finally beat them again, and it was easy to get them open.

Everyone tried this method, and found that it was very easy to use, and the rock immediately became very crunchy, and after a little beating, it was brought down.

Everyone couldn't help but admire Xiao Yu's talent. Xiao Yu pouted, this method is known to children on the earth.

It's just that it's not so easy to really implement, and it's very difficult to get such a lot of fire if it weren't for Kael'thas, a powerful fire magician.

And just like that, a little bit of burning, and then watering, the rock fell down in large chunks, and after about half an hour, with a bang, a large chunk collapsed on it, and then, revealing a huge crater, on which the golden sunlight shimmered.

And at this moment, Uther on the side suddenly burst out with an extremely blazing light on his whole body, shocking all the people around him and flying out.

"Ah......h
