Through rituals and other methods, Rhodes was able to release all the death energy contained in the Revenant Crystal for a period of time.

The death energy stored inside the Revenant Crystal, if all of it is released, with the blessing of quantity, even if the quality of a single Revenant Crystal is not very good, it can still have a considerable effect.

These changes produced by the Revenant Crystals during the ritual are similar to those of the Mother of the Revenant.

The Mother of the Revenant can easily mobilize the death energy in these Revenant Crystals, and if the Mother of the Revenant is involved in the process of holding the ceremony, then it can have an excellent effect and greatly save the time of the ritual.

But alas, the Mother of the Dead is not in Rhodes' hands. In order to advance faster, Rhodes gave the Mother of the Revenant to the Centaur Leader, who was able to quickly organize an army of the undead.

After disposing of these revenant crystals, Rod looked at Elon on the side.

Although Rod didn't say much, Elon immediately understood what Rod meant, and instead stepped forward, but stopped outside the circle surrounded by the Revenant Crystal.

At this time, Elon took out a vial from the spatial ring, placed it outside the ring, and then retreated again.

Rhodes stepped forward and took the vial in his hand, but without much confirmation, he uncorked the bottle and dripped the liquid from the bottle onto the surrounding Revenant Crystals.

Under the illumination of the surrounding flames, the liquid in the bottle dripped on the Revenant Crystal, showing a special red color, but it instantly disappeared into the Revenant Crystal, leaving only a dark red trace.

The liquid in the bottle was none other than Elon's blood, a medium item that had to exist in order to connect with the monster hero in the transformation ritual.

I don't know if it was because of the storage in the spatial ring, or if Elon had done some special treatment with the blood, when Rod dripped the blood from the bottle, the blood showed no signs of clotting, as if it had just been taken out of his body.

It seems that long before returning to Silvercliff City, Elon was ready, taking out the blood first, and applying special treatment, just waiting for the ritual to begin.

Although Elon is not a necromancer, through the narration of the rest of the necromancers, Elon also has a lot of understanding of the conduct of the transformation ritual, and knows that his own blood is needed in the ritual, not the necromancer's that performs the ritual.

Soon, Rhodes sprinkled all the surrounding Revenant Crystals with one or a few drops of Elron's blood.

After completing the main preparations for the transformation ritual, Rhodes began to arrange another spiritual suppression ritual.

Next to the light pot, in the space enclosed by the Revenant Crystal, some of the rest of the materials were placed. These materials were all collected by Elon according to Rod's orders.

Elon may not know much about how the necromancer directs the transformation ritual, but he knows that all he needs to do is to complete the collection of materials and the arrangement of the real ritual, or let someone who understands this come.

Rhodes noticed that among the rest of the surrounding materials, there were certain quantities of crystals and gemstones. In addition to this, there is also this sealed porcelain jar.

Rod set his eyes on the porcelain jar on the side, and through this conventional storage method, Rod was able to confirm that what was stored in the porcelain jar should be another medium in the ritual, mercury.

In addition to the Revenant Crystal, mercury, gemstones, and crystals, which are common ritual mediums, can be easily obtained as long as they master a certain channel, and all they need to spend is some gold coins.

Compared to the price of Revenant Crystals, these materials are more precious, but they are nothing.

In addition to the transformation ritual of the Death Knight, these materials are required for the general rituals performed by orthodox mages, similar to this ritual of suppressing spirits.

Due to the presence of a large number of mages in the territory, the consumption of ritual materials spent by Bracada every year is extremely huge, and Bracada is looking for new colonies everywhere and looting the resources in them, also to meet the needs of these mages.

Seeing the rest of the material, Rhodes knew that since mercury was so special, it should be arranged for final processing.

Rhodes reached out and took the materials and placed them in a special way, around the light pot, in the Revenant Crystal Circle.

Gems and crystals were laid out on the ground around him as Rod moved. Against the backdrop of the firelight, the whole ceremony adds a special color.

In the eyes of ordinary people, these materials needed to carry out the ritual are extremely precious, but neither Elon nor Rhodes spared these materials, but just let them be used as they should.

After processing the rest of the surrounding materials, Rod set his eyes on the porcelain jar on the side.

Rod reached out and took the sealed porcelain jar, but instead of opening it, he looked at the other two people in the space.

After sensing Rod's movements, Elon directly raised his hand and cast a spell on himself. After finishing the spell, Elon continued here, observing Rod's movements.

On the side, after receiving Rod's signal, Rowling didn't realize what she should do for a while, until she noticed the movements of Elon and Rod, and then she understood what Rod meant.

Through the records of some previous magic books, and Rod's frequent teachings, Rowling recalls that among all the things that can be used as ritual mediums, mercury is a very special being.

Mercury has the property of guiding spirits, and this degree of guidance is different from gemstones and crystals that are used for conduction alone, and mercury can be used to have a good effect in spiritual rituals. At the same time, in the field of alchemy, mercury also has a very high status and is an extremely important alchemical material.

While it has such a powerful effect, mercury also has a certain danger, mercury will spill into the air and come into contact without any protection, even for mages, there will be a certain danger.

In dealing with mercury-related rituals, mages usually choose to use air thaumaturgy to avoid the dangers of mercury, but the ritual needs to be carried out as soon as possible, otherwise the ritual will fail due to a large amount of mercury spilling.

After remembering this, Rowling was just about to unleash the imperial thaumaturgy for herself, but Rod's spell arrived first.

Seeing that Rowling didn't move for a while, after waiting for a while, Rhodes immediately took action, directly performing the qi thaumaturgy for Rowling, and at the same time performing it on himself, and then opened the porcelain jar that sealed the mercury.
