After feeling the wave, rod seemed to find something and looked behind him.

In rod's perception, it seems that the generation of this wave has nothing to do with the death energy released by him. The real inducement of this wave should come from his own rear.

Rod noticed that Rowling was standing behind him, looking at himself, holding an ordinary crystal of the dead. Rowling, also aware of the wave, was surprised.

Rod recalled that she had given her the ghost crystal before. In order to let Rowling master the art of evocation and the method of transforming the undead, the undead crystal is one of the most important items. Rod has already indicated to her how to use it.

The original wave was triggered by the ghost crystal in Rowling's hand. Guided by the surrounding death energy, rod locked the approximate position of the mother of the dead.

Rowling followed rod all the way to the tunnel behind the wall. When she noticed that rod seemed to be observing the surrounding walls all the time, and seemed to be perceiving something, Rowling also roughly guessed rod's behavior at this time.

Although she came to rod's side, Rowling didn't say a word to disturb rod. She didn't even make any noise. She was afraid of disturbing rod's perception.

Thinking of the undead creatures that originally appeared, Rowling could guess that the treasure rod was looking for should have a lot to do with the necromancer.

When rod releases the energy of death, but does not get any results, Rowling also wants to try to help rod find, but nothing is found.

In the process of searching, Rowling also noticed the damaged dead crystal around.

Seeing these ghost crystals, an idea flashed through Rowling's heart. With the guidance of this idea, Rowling took out her own ghost crystal from the space ring.

At the moment when the ghost crystal was taken out, because of the sudden appearance of the ghost crystal, the mother of the ghost immediately established a special connection with it.

Just as the necromancer controls the undead creatures, under the effect of this connection, the mother of the dead can control the release of death energy from the undead crystals. Because of this control, all the death energy contained in the former undead crystals erupted in a flash.

However, when Rowling takes out a new dead crystal from the space ring, the situation changes. The mother of the dead immediately establishes contact with the dead crystal, causing the fluctuation of the surrounding death energy.

Although the fluctuation only lasted for a moment, due to the close distance and the fact that rod had been paying attention to the movement around him, he immediately determined the location of the mother of the dead.

When he saw the ghost crystal in Rowling's hand, rod immediately figured out what was going on around him. But without Rowling's behavior, it might take some time for rod to think about this method.

In addition to the crystal of the dead in Rowling's hands, the death energy released by rod also plays a sufficient role in searching for the mother of the dead.

these Without the guidance of death energy, rod could not easily find the position of the mother of the dead.

It can be said that in the process of searching for the mother of the dead, if there is no one less, the two can not achieve such good results.

Looking at Rowling who doesn't understand what happened in the rear, rod realizes that the act of taking out the ghost crystal may have been completed by her mistake, but it is her act that has saved her a lot of time.

Having found the location of the mother of the dead, rod stopped waiting and began to use his magic to smash the rock wall in front of him. Then he used the original pick to clean up the gravel.

Feeling rod's action, the mother of the dead in the mountain wall immediately understands that her position has been exposed, but there is no way.

In Rowling's perception, the ghost crystal in her hand began to shake violently. Rowling subconsciously released her hand and threw the ghost crystal on the ground.

As soon as the undead crystal fell to the ground, it was directly broken into several pieces, and all the death energy contained in it was scattered around, and finally it was only integrated into the death energy originally released by rod.

The mother of the dead can effectively mobilize the death energy in the crystal of the dead, even raise the level of the dead creatures, and control the dead creatures, but it can't release the attack spells similar to the death cloud like a necromancer.

Because of the instinct of the mother of the dead, she doesn't want to be controlled by any creature. When she discovers rod's intention, she becomes crazy.

At the same time, all the ghost crystals contained in the whole mine cave began to riot, releasing a lot of death energy towards the surrounding.

In an instant, there was a violent vibration inside the mine cave. It seems that the whole mountain where the mine cave is located began to collapse because of the behavior of the mother of the dead. Even the ground beneath rod's feet began to crack.

After discovering this, rod knew that he had to seize the time.

After giving Rowling a simple command to leave the mine from the original tunnel, rod focused on digging the front wall.

Because he can use a spell to directly break up most of the rock wall in front of him, rod is extremely fast in digging, even using Titan's arrow, just to speed up his own speed.

The only thing to note is that rod's mana value is not much. In order to find the position of the mother of the dead, rod converted half of his mana value. With the continuous use of spells, the remaining mana value is not much.

At this time, the surrounding vibration is obviously intensified. There are many undead crystals in this mountain. Under the control of the mother of the dead, all the energy of death will burst out. The impact is extremely severe.

In the process of digging, a spell hit the front of the rock wall, breaking a large rock.

This spell was not cast by rod himself, but by Rowling in the rear. In this case, rod did not have time to ask Rowling why he had not left here, so he could only hit the pick in his hand on the rock wall in front of him.
