After feeling the fluctuation coming from him, Rod seemed to have noticed something, and looked back behind him.

In Rod's perception, the generation of this fluctuation does not seem to have much to do with the death energy released by himself, and the real cause of this fluctuation should come from his rear.

Rod noticed that Rowling was standing behind him, looking at him, holding an ordinary Revenant Crystal in her hand. Rowling also sensed the fluctuation that appeared, and looked a little surprised at this time.

Rod recalled that the Revenant Crystal in her hand was given to her by herself before. In order to let Rowling master the art of spiritualism and the method of transforming undead creatures, the Revenant Crystal is one of the most important items, and Rhodes has already shown her how to use it.

The original fluctuation was caused by the Revenant Crystal in Rowling's hand, and through the guidance of the surrounding death energy, Rhodes locked the approximate location of the Revenant Mother.

Rowling followed Rhodes to the passage that appeared behind the mine wall. When she noticed that Rhodes seemed to be observing the walls around him all the time and seemed to be sensing something, Rowling also roughly guessed Rhodes' behavior at this time.

Although she came to Rod's side, Rowling didn't say anything to disturb Rod, and she didn't even make any sound, for fear of interfering with Rod's perception.

Thinking of the undead creatures that appeared before, Rowling was able to guess that the treasure that Rhodes was looking for should have a lot to do with the necromancer.

When Rhodes unleashed his death energy but didn't get any results, Rowling also tried to help Rhodes find it, but found nothing.

In the process of searching, Rowling also noticed the destroyed Revenant Crystals around her.

When she saw these Revenant Crystals, a thought flashed through Rowling's heart, and with the guidance of this thought, Rowling took out her Revenant Crystals from the spatial ring.

The moment the Revenant Crystal was taken out, due to the sudden appearance of this Revenant Crystal, the Mother of the Revenant immediately established a special connection with it.

Just like the necromancer's control over undead creatures, under the effect of this connection, the Mother of Revenant Souls can control the release of Revenant Crystals into the energy of death, and it is precisely because of this control that those Revenant Crystals will burst out of all the death energy contained in them in an instant.

Since the Mother of Revenant has been around here for an unknown amount of time, long before Rhodes arrived, and even before this mine was mined, these Revenant Crystals had been controlled by the Mother of Revenant, and this control was nowhere to be found, and it was impossible to guess the location of the Mother of Revenant Souls by relying on the Revenant Crystals here.

However, when Rowling took out a new Revenant Crystal from the spatial ring, the situation changed, and the Revenant Mother immediately established a connection with the Revenant Crystal, triggering fluctuations in the surrounding death energy.

Although the fluctuation only lasted for a moment, due to the close distance and the fact that Rhodes had been paying attention to the movements around him, he immediately determined the location of the Mother of Revenants.

When he saw the Revenant Crystal in Rowling's hand, Rhodes immediately figured out what was going on around him. But without Rowling's actions, Rod might have had to think about it for a while before he could think of this method.

In addition to the Revenant Crystal in Rowling's hand, the death energy released by Rhodes also played a sufficient role in finding the Mother of Revenants.

Without these dying energies around her, the Mother of Revenants would not have a distinct feature when she was connected to the Revenant Crystal. Without the energy of death as a guide, Rhodes could not easily discover the location of the Mother of the Dead.

It can be said that in the process of searching for the Mother of the Dead, if the behavior between the two is missing either party, they will not be able to achieve such good results.

Looking at Rowling, who didn't understand what was happening, Rod realized that the act of taking out the Revenant Crystal may have been done by mistake by her, but it was her act that saved her a lot of time.

Having found the approximate location of the Mother of the Dead, Rhodes waited no longer and began to smash the rock wall in front of him with a spell, and then used his original pickaxe to clear the rubble.

Feeling Rod's movements, the Mother of the Dead in the mountain wall immediately understood that her location had been revealed, but there was nothing she could do.

In Rowling's perception, the Revenant Crystal in her hand began to vibrate violently, and Rowling subconsciously let go of her hand and threw the Revenant Crystal to the ground.

As soon as the Revenant Crystal landed, it was directly shattered into several pieces, and all the death energy contained in it was scattered around, and in the end it was only integrated into the death energy originally released by Rhodes.

The Mother of the Revenant can effectively mobilize the death energy inside the Revenant Crystal, and can even increase the rank of the undead creatures, and control the undead creatures, but it cannot unleash offensive spells similar to the Cloud of Death like the Necromancer.

Due to the instinct of the Mother of Souls, she did not want to be controlled by any living being, and when she found out about Rod's intentions, she also became insane.

At the same time, all the Revenant Crystals contained in the entire mine began to riot, releasing a large amount of death energy towards the surrounding area.

In an instant, there was a violent vibration inside the mine, and the entire mountain where the mine was located seemed to have begun to collapse violently because of the behavior of the Mother of the Revenant. Even the ground beneath Rod's feet began to crack.

After discovering this, Rhodes knew he had to hurry.

After giving a brief order to Rowling to get out of the mine through the tunnel, Rhodes focused on digging the wall ahead.

Due to his ability to use spells to directly shatter most of the rock wall in front of him, Rhodes was extremely fast, and even used the Titan Arrow, just to speed up his own speed.

The only thing to note is that Rod's mana is running out, in order to find the location of the Mother of Souls, Rhodes transformed a small half of his mana, plus the successive use of spells, there is not much mana left at this time.

At this time, the surrounding tremors intensified significantly. Inside this mountain, there are many revenant crystals, and under the control of the mother of revenants, all the death energy in them burst out, and the impact is extremely violent.

As Rhodes was digging, a spell struck the rock wall in front of him, shattering large chunks of rock.

This spell was not cast by Rod himself, but by Rowling in the back. In this case, Rod didn't have time to question Rowling about what he had not left here, so he could only hit the pickaxe in his hand hard against the rock wall in front of him.
