"Mr. McLean, why are we here?" erns looked at the stone debris and earth blocks and collapsed and blocked tombs around him, and couldn't help asking Marca, "and must go so deep?"

Yes, that's the problem - if you just want to find a place to study the devouring mirror, there are many places for Maka to choose. In that case, why do you have to come to the underground palace that once sealed Haier Bo?

However, I didn't expect that Maka's answer was extraordinarily simple.

"Isn't it just to dig his soul coffin?" Marca, walking in front, waved away the rubble and soil blocking the road ahead, and said casually, "you told me that! Didn't you?"

"Ah!"

Hearing the speech, Ernst nodded suddenly.

Yes, it is precisely because halber mentioned to him that the material Slytherin used to seal his wooden coffin came from the soul wood, a special tree species planted by herchpatch himself. That's why Maka decided to come here.

Soul wood is a rare magical tree species. In this era, he has never seen it anywhere except some hand-painted brochures in ancient times.

Therefore, if you want to get the soul wood, it seems that you can only come to this place.

At present, Maka is constantly cleaning the tomb path and taking erns to the depths of the underground palace - he has been here many times in order to study the bewitching monument. Although the underground palace is quite huge, and now many tombs have collapsed and destroyed, he still knows exactly how to get to the main tomb where the bewitching monument was stored.

"Boom -"

Perhaps when opening the huge rock, he accidentally damaged the supporting structure, and this section of the tomb path suddenly vibrated. With the sudden fracture of several remaining stone pillars, a large number of bricks and sand fell from above their heads.

"Be careful... Float off."

It has to be said that Ernst worked very hard in the training of casting spells. Seeing a lot of bricks falling from the top, he almost reflexively pulled out his usual wand and cast a floating spell upward.

"Oh, thank you."

Maka, who was trying to block the falling rocks, immediately smiled at Ernst, and then suddenly raised her hand to the top.

Then, all the bricks and stones that had fallen frequently just now stopped for a while, then they rose up again and were pushed back directly by a huge force.

Before long, this section of the originally collapsed tomb path was repaired by Maka in a somewhat "rough" way.

"All right, move on!"

After all this, Maka waved her hand and walked on. Behind him, Ernst hurried up.

"Mr. McClain, why don't you repair the spell?" Ernst asked suspiciously, not far behind Maka, reaching out to touch the wall of the new tomb path compacted by Maka.

"Because it's not necessary," said Marca. "I'm just here to pick up things, but I'm not going to repair it like my new home."

A moment later, as Maka kept on driving ahead, the two people who barely stopped at their feet soon came to the end along the main tomb path.

As Maka said before, along the way, Ernst had seen that many tombs were still intact and did not collapse because of the violent vibration when halbo broke away from the seal.

In particular, the last extremely huge main tomb, because it originally needed to store a huge bewitching monument, this tomb not only has a large space, but also has no stone column support at all.

The reinforcement magic here still maintains its due effect up to now. Except that some areas can't resist the great power of halbo when he comes out from the ground and collapses, they still maintain their original appearance.

"Well... But if you have to say, maybe it's a good choice to turn this place into an underground shelter." Maka whispered as she walked in. "At least, that guy Haier Bo probably won't want to come here again in his life!"

"Really?" said Ernst with a frown. "That guy's idea doesn't seem to be very normal. Maybe he won't mind?"

Maka shrugged when she heard the speech.

"I just said it casually," he said. "However, it is estimated that even Haier Bo, who is different from ordinary people everywhere, would not like to 'revisit his hometown' in such a place - you know, he has been sealed under the ground for thousands of years! I'm afraid he's already completely crazy."

Of course, Maka is just talking nonsense. He won't really turn the underground palace into a shelter.

While chatting with Ernst, he has begun to clean up the area in the middle of the main tomb.

With a wave of his backhand, he swept all the rubble scattered on the ground aside, and then he saw a big hole that was still dark under the light.

After discovering the cave, Maka didn't seem to have any intention of going in, but suddenly waved to the deep part of the hole.

The next moment, Ernst saw a large amount of soil mixed with gravel gushing out of the ground, which was piled aside under Maka's control.

With the earth and rock surging for a while, Maka suddenly seemed to feel something and slightly raised her eyebrows. Then he and Ernst saw that some wood fragments began to be turned over in the concrete.

When Maka saw this, she immediately waved and let one of the palm sized pieces of wood suddenly turn around and fly to herself, which was accurately received by him.

"Hmm?" Maka looked back and forth, and wondered, "this is the soul wood?"

To tell you the truth, if you look at ordinary wood, it is rare in the world that this piece of wood has been buried underground for nearly a thousand years and still has no decay.

However, it is light and dry and loose when pinched, as if it would be twisted into debris with more strength. Is this state really useful?

Or... After all, is this really the soul wood?

With such doubt, Maka waved again and continued to turn deep underground. It was not until he finally dug out a still intact coffin side plate from the ground that he was completely sure. It seemed that the wood that could be smashed in his hand was part of the wooden coffin used to seal Haier Bo.

"It's enough to put a fragile label on this thing!"
