After two hours, and a near-waste of material due to a mistake, Sean finally advanced the progress of the rune and energy circuit carving of the spine to a tenth of the progress.

The making of the staff is not something that can be done overnight, and after leaving for lunch, Sean returns home to continue his unfinished business.

Meditation – the depiction of runes and energy circuits – is enhanced with auxiliary materials.

In this cycle, time passed quickly, during which Sean devoted himself to the transformation of the backbone of the mine-eating beast, in addition to eating and buying some necessary supplies.

Finally, two days later, the spine had been carefully carved by Sean for two days, and finally met his wishes.

Because he only has an apprentice-level alchemy level, the runes and energy circuits that Sean now depicts only occupy a small part of his backbone, which can facilitate him to upgrade his staff in the future, saving him the effort of remodeling.

Normally, the main body of a staff is composed of four parts, namely the head, core, body, and tail, and some of the staff will also add some external decorations to make the staff have more abilities.

The method of making the staff of reincarnation is very flexible, and these five parts can be swapped at will, and there is no confinement to a certain order.

For example, Sean can use the spine of the mineral-eating beast as the head, core, and tail of the staff, and the silver vine as the body and exterior decoration, that is, the spine is inside, and the silver vine is wrapped outside.

It is also possible to use the silver-devouring vine as the head and core of the staff, and the backbone of the mineral-eating beast as the body and tail of the staff, so that the staff looks like a vine growing from the top of a bone.

In the end, Sean chose the first option, but he had a secondary fusion crystal in his hand, and after much consideration, he decided to make a preliminary change to it.

Using the secondary fusion crystal as the head of the staff, the backbone of the mineral-eating beast as the core and tail of the staff, and the silver-devouring vine as the body and exterior decoration of the staff, this combination can perfectly play the role of the secondary fusion crystal, and also reduce the burden on the backbone of the ore-eating beast.

After looking at the silver-devouring vine that was growing vigorously on the side for a while, Sean took the mineral-eating beast's spine on the table and inserted it next to the silver-devouring vine.

The next thing he did was to let the Silver Devouring Vine grow on the backbone of the Mineral-Eating Beast, and then fuse the two together, linking its runes to the energy circuit.

To achieve this effect, it is necessary to use spells, and after adjusting the position of his spine, Sean began to cast spells.

Alchemy is a profound science, as it involves not only the use of spells, but also many further techniques.

Some of the runes and energy circuits engraved in the Silver Devouring Vine have some special effects, including the effect of responding to Sian's mana control.

"Apprentice Spell - Enhanced Plant Growth"

In the chant of the incantation, Sean used his mana to control the silver vine to change himself.

The first is rapid growth, the silver-white silver-devouring vine under the control of Sean, gradually wraps around the spine of the same silver-white mineral-eating beast, wrapping it tightly, except for the tail to show a section, even the top has only a small hole that is convenient for the spine to connect with the head of the staff in the later stage.

Then, the silver-devouring vine encircled the inner part of the spine, and gradually began to grow fibrous roots, which were connected to the nodes left by Sean on the spine.

This step was a drain on Sien's energy, and after confirming that all the fibrous roots were aligned, Sean gave the order to continue growing.

As if encountering a nemesis, the fibrous roots silently plunged into the hard bones.

Although the Silver Devouring Vine does have the ability to devour silver and mythril, the speed is far from being as fast as it is now, and the reason for this phenomenon is actually the result of Sean's early transformation.

After letting the root system of the Silver Devouring Vine spread all over the inside of the mineral-eating beast's backbone, Sean finally breathed a sigh of relief.

It is not easy to control the growth of a plant, but fortunately, his technique is not bad, and he finally completed this step.

The next step is to allow the combination to grow for another two days to further deepen the integration of the two, during which time Sean will not only not be able to pull it out of the soil, but will continue to add a large amount of material to the soil for support.

The transformation of the secondary fusion crystal was the most difficult to complete, and in order to make it a part of the staff, Sean had to burn runes and energy circuits on it, and link it to the other two parts.

But there is a very important problem that if such a crystal is carved at will, the damage caused will be irreversible, and it will destroy its structural balance, so that the effect of the crystal will be reduced to a certain extent.

Therefore, Sean decided to take the method of depiction, drawing the runes and energy circuits of the secondary fusion crystals from both internal and external aspects.

This method is a lot of work, and the auxiliary materials required are relatively expensive, but fortunately, he had borrowed five hundred gold coins from Satuk before, otherwise he would not have been able to complete this step.

Exterior painting is simple, but of course, it requires the use of some special materials.

From morning to noon on the third day, it took Sean a little time to draw all the runes and energy circuits he could do so far on the surface of the secondary fusion crystal.

Then there is the inner part of the crystal, and the operation here is not so simple, and it requires some more high-end techniques to do it.

To put it simply, it is to use spells to integrate some materials into the secondary fusion crystal, and use spiritual power and other methods to form three-dimensional structures inside the crystal, and these structures echo the outside and produce magical effects.

Fortunately, the nature of the secondary fusion crystal itself is very suitable for this kind of alchemy transformation, so even if it fails, there will be no consequences, and as Sean's proficiency grows, he finally solves this problem that night.

Holding the crystal in his hand, Sean poured mana into it, and after swimming a few laps in the runes and energy circuits, he confirmed that everything was correct.

He brought the crystal to the side of the potted plant, and after two days of running-in, the backbone of the mineral-eating beast and the silver devouring vine had basically merged, and the free ether gradually converged on the runes, and flowed into the energy circuit to circulate continuously.

Carefully placing the secondary fusion crystal on a tray made of the silver-devouring vines, and placing a lot of silver in the dirt, Sean used the spell again.

Under the effect of the spell, the silver in the soil was quickly devoured by the silver devouring vine, turning into food for its growth.

The silvery-white vines beneath the crystal gradually recessed, and the top of the mineral-eating beast's spine was exposed, perfectly fitting with the crystal.
