Through his previous understanding of the potion competition, Rhodes already knew that the potions refined by North could replace the deep meditation of the mage and directly improve the spiritual attributes of the mage.

Because of this, when Rhodes faced the problem of insufficient control of mental attributes, Rhodes came up with a solution that improved his control mental attributes through the potion refined by North.

In Rhodes' opinion, since the potion refined by North can replace deep meditation and improve the spiritual attributes of the mage, then as long as the refining method of the potion is changed, North can also refine the potion that improves the control spirit.

Through deep meditation, the mage has a certain limit on the improvement of spiritual attributes, and if he does not improve his own rank, when the improved spiritual attributes reach a certain value, he will not be able to continue to improve.

However, the mage does not have such a restriction on the improvement of the control spirit attributes, and if the mage is willing, he can greatly improve his control spirit through deep meditation.

The process of improving the spirit of manipulation takes a lot of time for a mage, and only those lichs who are no longer confined by their physical bodies can do this.

In Rhodes's impression, among the various potions that existed in his previous life, the potions that can improve the control of spiritual attributes are also the most special one.

Unlike potions that improve spiritual attributes, only one bottle is needed to achieve the maximum effect of the boost, and even if other potions are used later, the improvement of spiritual attributes will only choose the strongest one. Potions do not have such a restriction on the improvement of mental attributes.

Depending on the main material used to refine the potion, the mage can drink the potion that increases the control of the spirit attribute multiple times, so as to improve the control of the spirit of the person.

The effect of potions on the improvement of the manipulation spirit can be stacked multiple times, thus greatly increasing the manipulation spirit attribute of the mage.

There is still a limit to the maximum improvement that potions can bring to the control spirit, and after that, if you want to continue to improve your control spirit attributes through potions, you can only choose a higher quality main material for refining.

However, according to Rod's understanding, before the improvement is maximized, the increased control spirit attribute is enough to solve the problem of his own lack of control spirit, allowing him to control a large number of undead creatures.

Of course, all this is based on the fact that North is willing to refine potions for himself, and if North does not agree to this, it will be difficult for even Rhodes to refine potions that improve the control of mental attributes.

Just as North thought, Rhodes's focus on the refining of potions was not on spiritual attributes. This was confirmed by Rod as early as the rematch was underway.

If Rod chooses to refine a potion that improves the control spirit attributes, the real effect of the potion will not be much better, and the improved control spirit attributes may not meet Rhodes' expectations.

Because of this, Rod's choice was to find North, who had noticed in the Potions Competition, and ask him to help him refine potions.

But, as if noticing something, Rhodes knew that North didn't seem to be going to easily accede to his request.

"It's true that I'm able to refine potions that enhance the spirit of control, but I don't seem to have the need to do it for you."

"You don't know yet, Rod, now that you've been expelled from the Spiritual Society. Your escape from the finals of the Potions Contest nearly ruined the Guild's plans! ”

"If it weren't for Earl, who also participated in the finals and ranked third, to convince the leaders of the Magic Guild, all the necromancers who participated in the Potions Competition would be punished by the Magic Guild for your actions."

As if remembering Rod's last behavior, North couldn't help but feel a trace of anger in the process of rejecting Rod.

Recalling the information he had gathered in the Spirit Society, even though Rod's strength was far superior to his own, North did not show any awe and directly rejected Rod's request.

In North's opinion, Rod, who has lost his status as a spirit and has to be punished by the spirit society, is not in a much better situation than himself at this time, even if he has no way to join the magic academy, he will not be like Rhodes, who may be retaliated by the spirit at any time.

In addition, North also knew that the reason why Rhodes might be in danger was not only because Rhodes did not complete the tasks assigned by the Spirit Guild, but also because of the artifact parts that Rhodes obtained from the Potions Competition.

According to North's understanding, many powerful necromancers in the Spirit Society who want to attack Rhodes have a real purpose of the artifact parts in Rod's hands, and even in the territory of Bracada, some really powerful mages also want to get the artifact parts in Rod's hands, but because of their identity, they can't find a chance to attack Rod.

In the final moments of the Potions race, the powerful effects of the artifact parts undoubtedly appeared in the eyes of all mages.

The mage on the airship personally felt the impact of the artifact part on the forbidden demon ceremony, so he learned the power of this artifact part, and the mage under the airship also learned this from the information collected afterwards.

After feeling the power of the artifact part, and knowing that this artifact part is in the hands of a necromancer, any mage will have some thoughts about it, and the improvement that the artifact part can bring, even for a high-level mage, will also have a great effect.

In this case, most of the dangers that Rhodes may encounter come from this, if Rhodes' strength is insufficient, he will not be able to hold the artifact parts on his body at all, and he will be snatched by other powerful mages at any time.

Even in the territory of Bracada, the mages will not easily let go of the opportunity to improve their strength, if Rhodes is an ordinary mage, maybe the situation will improve slightly, but the identity of the necromancer has doomed Rhodes to many dangers.

Even North was also eye-catching at the artifact parts on Rod's body. It's just that North deeply understands in his heart that there is a gap in strength between him and Rod, so he won't make any unusual moves, but just refuses Rod's request.

As for why Rhodes fled from the airship immediately after getting the artifact parts, North also had some understanding in his heart.

North knew that this act of Rhodes could avoid the danger that might come to him to the greatest extent, but even so, North did not intend to refine potions for him as Rod said.
