In the process of moving towards the depth of the mine, rod met many necromancers and the undead creatures beside them. For a few of them, rod had some impression. It seemed that he had seen them in Sao city.

In perception, the energy of death has covered the whole mine. The trace of the necromancer has deeply infected the land. Among them, the place with the most abundant energy of death is also the deepest part of the mine.

The grudged souls gathered in the mine cave had already noticed the arrival of rod, and the energy of death on him became more and more strong. Even the action of mining minerals was much faster. Rod could clearly feel this.

Following the signals from his perception, rod moves towards the depth of the mine. In addition to the strong energy of death, rod can also feel the strong spatial fluctuation left here. This discovery now undoubtedly shows rod that Rowling, who arrived here first, has gained a lot.

In addition to the space calibration in Sao City, rod did not give Rowling any other space calibration. She was able to transport the necromancer in Sao city to this place with the help of space magic. Obviously, she found something in this emerald mine. Maybe she has found a lot of gems for space calibration.

What makes rod care is that Rowling's breath has not changed for a long time. It always exists in the depth of the mine. It seems that he has been waiting here for a long time. After realizing this, rod speeds up his pace and wants to find Rowling.

It is different from the original green things to cross the various obstacles in the mine cave and move towards the deep. The closer to the depth of the mine cave, the more complete the original stones are around. You can't see what it contains. The most precious space calibration is hidden in the airtight original stones.

Depending on the fluctuation caused by space magic, the caster who has mastered the gate of time and space can detect the spatial calibration within a certain range, especially in the mine where the spatial calibration is produced. This ability undoubtedly provides great help for searching for space gems. I believe Rowling made the same use of it.

Ignore the surrounding things, soon, when rod came to the deepest part of the whole mine, finally saw the figure of Rowling.

At this time, Rowling, with her back to rod, stood in front of a relatively complete mine wall, playing with a crystal in her hand. The crystal's dark green light illuminated the whole space, and the shadow stretched behind Rowling until it reached rod's feet.

Looking at the familiar dark green light, rod realized that what was in Rowling's hands at this time was the space gem he was looking for.

The quality of this space gem that Rowling holds is far better than what rod has ever seen. Even the best space gem in rod's hand, that is, the one on the broken crown, is not as good as the one in front of him.

He followed rod to Vera in the deep of the mine. He didn't say much on the way, but he was always observing the situation around him, trying to find information beneficial to him from the surrounding environment.

The figure in the depth of the mine cave was also seen by Vera. Looking at the person in front of her, Vera seemed to recall the rumors about the Lord and could not help observing carefully for a moment.

As if aware of the arrival of rod, the figure in front of him turned around. Vera, who was watching, shrunk her pupils. At the same time, she could not help but take a step back. It took her a long time to recover.

Vera noticed that the figure in the depth of the mine was somewhat similar to the Lord in appearance, but it was softer in outline. There was a deep defect on one side of the face, which was the trace of death energy erosion.

On weekdays, Vera has already seen many strange looking necromancers, but because of the special environment here and the dark green light reflected on the wall of the mine, she is still shocked by the scene.

Noticing the Lord's bad look at him, Vera immediately realized that his action was wrong. After standing still, she lowered her head and did not dare to look at the person in front of her.

Seeing Vera's action, rod gave a cold hum and didn't say much.

Coming to Rowling, rod can clearly see Rowling's face at this time with the help of the dark green light of space gems.

Previously, traces of death energy erosion still exist on Rowling's body. Half of her face is incomplete. It seems that during this period, she did not use energy absorbing secret method to recover her body.

Looking at Rowling in this state, rod had an inexplicable feeling in his heart, but he just asked indifferently: "how is the spatial calibration collection going?"

Hearing rod's inquiry, Rowling took out two other dark green gems of the same size from her pocket and handed them to rod together with the one she held first.

"From the existing area of this mine, a total of three spatial calibrations have been found, so that the undead can continue to dig, and there may be more harvest."

After learning the number of space calibration from Rowling, rod engraved his own spiritual imprint on these space gems in his hands, and then handed back the brightest one, the one that existed in Rowling's hands at the beginning.

"Put it away and take it with you all the time."

Hearing rod's words, Rowling felt warm. Rowling, who knows the precious degree of space gems, did not refuse rod's kindness. After taking the gems, she carefully put them close to her.

Naturally, rod's intention of giving Rowling space calibration is to use the unique ability of space calibration to determine Rowling's location, and then to be able to appear beside Rowling directly through the gate of time and space when necessary.

Depending on the existence of consanguinity perception, rod can perceive the general state of Rowling, which undoubtedly makes rod more clear when to use space magic to go to Rowling.

With enough space calibration, many unique tactics can be implemented. For rod, this is undoubtedly another level of improvement.

As Rowling said, when the undead completely cleans up the mine near the Emerald City, more space gems will be found. In addition, the emerald excavated in the mine is also a large fortune.

The undead has no skill to dig, which can't guarantee the integrity of the jadeite in the mine cave. In the end, they can only get a lot of broken jadeite gravel. Even so, after they are sold to the freelance chamber of Commerce, they can also exchange a lot of gold coins, which is enough to meet the demand of magic medicine refining for a long time.
