The means of detecting the bond between trainers and elves have been around for a long time, and there is more than one way.

Some people can confirm the relationship between the trainer and the elf by observing, and some people can confirm the relationship between the trainer and the elf through special items, and there is a special prop in the main hall of the Sara Gym that can confirm the relationship between the trainer and the elf - a stone slab.

Although such a thing may not seem to be a big deal, in fact, this kind of prop that can test the bond between trainers and elves is still very rare, and it is only in the Daoist Hall that it has been inherited for a long time that retains a few items that are very convenient to put now, otherwise even some big families that have risen with the alliance after the establishment of the alliance may not have such a thing.

Karp was a little curious about the slate after listening to the old man's introduction, but the old man didn't say anything about it, just got out of the way and made room for Karp.

"Release the elves you want to evolve into, but if you want to test the bond, you can only test it with one elf at a time, you can put your hand on the right side of the slate and let it touch the left side of the slate."

Hearing the old man say this, Karp nodded, first releasing his own Geng Ghost, and then releasing his own big steel snake.

For the two elven old men released by Karp, he glanced at the big steel snake but didn't say anything, and then Karp first touched the stone slab with his Geng ghost.

As Karp and Geng came into contact with the slate, Karp felt an invisible force burrow into his body and surging into his brain along the location of the slate, and then the memories between him and Geng gradually emerged, and then when these memories disappeared, the entire slate turned green.

Seeing this result, Karp's eyes were on the old man.

The old man smiled at Karp when he saw the slate turn green.

"The slate turning green means that the bond between you and your elves is enough for you to evolve."

After explaining the current situation, the old man motioned for Karp to take his hand down, and waited for the color of the slate to regain before proceeding.

However, the old man was still like that on the surface, but in his heart he was still a little surprised by the level of bond between Karp and Geng.

After all, generally speaking, the bond level of trainers and elves is not up to the requirements of mega evolution, and the old man originally prepared a training plan for Karp and elves to improve their bonds, but now it seems that at least this Gengar is useless.

While the old man pondered these things, Karp waited for the color of the slate to return and then put his hand on the slate again.

Only this time, it was not Geng Ghost who touched the slate with Karp, but the Great Steel Snake.

However, unlike the hand-held elves like Geng, the big steel snake directly tapped the slate with the sharp part of its tail, and then what happened before happened to Karp again.

But the big steel snake was a little dazed, and waited until Karp's side was over, and the slate did not change at all, as if it had lost its effect.

The old man was even more surprised than he had just been when he saw this, he first asked Karp and the Great Steel Serpent to retreat with Karp's inquiring gaze, and then he himself tested it with Lucario to confirm that the slate was still useful, and then looked at Karp's Great Steel Serpent in surprise.

After all, the slate is fine, and the Karp who was successfully tested before is fine, so the problem can only appear on the big steel snake.

At this time, Karp also remembered that the body of the big steel snake was made of vibranium, and if that special energy was to be transmitted along the tail of the big steel snake, it might be directly blocked by vibranium, and if that energy was blocked, the slate would probably have no effect.

Knowing this, Karp patted the big steel snake on the lowered head, comforted it a few words, and then took the big steel snake back to the Poké Ball.

"My big steel snake has a special physique, maybe this stone slab is useless to it."

The old man listened to Karp's words and spread his hands at him.

"Then we can't do anything on this side - but if we can't test it with our method, you can also find other methods, and it just so happens that we don't have the mega evolution stone of the big steel snake on our side, so even if it is measured, you can't actually complete the mega evolution of the big steel snake here."

Because the old man had explained what the MEGA Evolution Stone was before, he said it directly at this time, and Karp already knew what the MEGA Evolution Stone was, so he just nodded at this time.

Karp doesn't have much regret about the fact that there is no mega evolution stone of the big steel snake in the Soluo Dao Pavilion, after all, it may be more difficult for him to get into other mega evolution stones, but the mega evolution stone of the big steel snake, if he goes to find ash, I believe he can get some clues.

So, he heard another meaning to the old man's words.

"I'll figure out the MEGA evolution stone of the big steel snake myself, but listen to what you mean, you have Geng Ghost's MEGA evolution stone here?"

The old man nodded in response to Karp's inquiry.

"Yes, and there are extra keystones, so since the bond between you and the Geng Ghost has passed, then let's go and get the Geng Ghost's Mega Evolution Stone and the keystone to wear for you.

Once you've got all the items on, it's time to try to evolve your Gengar MEGA. ”

Karp nodded somewhat excitedly at the old man's words, and Geng Ghost was in a similar mood to Karp.

After all, when he faced the old man's Lucario before, Geng Ghost had already seen how much the MEGA evolution could improve the elves, so at this time, it was more or less looking forward to its strength after completing the MEGA evolution.

The old man didn't say anything when he looked at Karp and Geng Ghost's excited looks, after all, the most difficult thing to make the elf mega evolve is the strength and bond of the elf and the trainer, if these two points are enough, then as long as the evolution stone and keystone are worn, the next step will be logical for the elf to complete the mega evolution.

If there is still a problem now, it is probably only the situation where the strength of the Geng Ghost MEGA has increased by leaps and bounds, resulting in Karp and himself being unable to control it, but that is after the MEGA evolution.

Thinking of this, the old man glanced at Karp, first felt the breath of the incomparably powerful superpower in his body, and then felt the incomparably large but unawakened waveguide power in his body, and after confirming these two points, the old man was not worried about the matter of Geng Ghost going berserk at all.

After all, with Karp's superpowers and the power of the waveguide, it is enough for him to manipulate the divine beast to fight, so even if Geng Ghost shows signs of rampage after his strength improves, the old man believes that Karp can suppress Geng Ghost.

So as long as he gets the Evolution Stone and Keystone, and then sees him complete a mega evolution with his own eyes, the matter of helping him complete the mega evolution will be over, and when the time comes, you can talk to him about the special ability and the power of the waveguide.
