Although the fierce big cat was bound by Tang En's net of heart power, she did not surrender. Instead, she refused to let go while making a soul-eroding cry, biting and grabbing the invisible heart power field.

"Mr. Grandpa, is Grace okay? What's wrong with her?" Kana's eyes were filled with worry.

A white light flashed in Tang En's eyes carefully sensed Grace, and waved his hand at the same time:

"Maybe it's because of insufficient spiritual cultivation, so it's like this. It's okay, let's see me awaken her."

As he said that, Tang En waved his hand and a solemn and calm white light hit the cat's head instantly.

"Meow..." The big cat screamed vigilantly, but the sound became smaller and smaller. Then the big cat closed a pair of fierce eyes weakly and fell to the ground.

‘Buzz’

After falling to the ground, Grace's body blew up from a thick dark green soul rule, covering her whole body, and then the big cat's body shrank and slowly turned back into a human form.

"Grace!" Kana flashed over worriedly, and at the same time took out a complete witch robe to cover the slightest Grace.

3.4 minutes later, Grace got up in confusion with exhaustion: "I, what's this? Kana~"

Kana immediately re-described Grace's situation: "Why, you don't remember these things just now?"

Grace shook her head and put the wizard robe in hand: "I don't remember it, I only remember when the last thunder came down, I suddenly felt extremely angry in my heart, and I didn't remember what happened next."

Tang En walked over with a smile: "Yes, this is because your mind is not inadequate. You need to temper your mental strength and your will, especially you, Kana!"

"Mind thoughts? What is that?" Grace asked curiously.

"Thoughts are the general term for mental power and will. In the past, wizards only practiced mental power, but no one had a systematic way of practicing will, so you don't understand~" Tang En smiled mysteriously.

In fact, he only understood this concept after traveling to the Boiling Blood World, but this did not prevent him from bragging about Qiao Muya.

Grace and Kana opened their eyes wide, then looked at each other, and asked in unison: "Mr. Mian, how do you need to exercise your thoughts?"

"Haha~, this is a secret technique that can only be exchanged for the demon clan. However, seeing that you have spent so many years on the demon clan, I can teach you the introduction to the secret technique, come on!" Tang En smiled and waved 2 white lights.

The mental power given by Tang En is extremely simple. There are no essays or long-term discussions. It just revolves around a word "confidence", and a few words that come from hypnotize yourself.

If it were someone from Tang En's previous life, he would probably not think that he was a cult member and would have to scold him for being a crazy person.

Grace and Kana were stunned, but woke up in a moment.

"Ah? Crown, this, this secret technique is that simple?" Grace couldn't believe it at all.

"Hehe, it's that simple. This is just the foundation of the foundation, but the power of the mind is a way to cultivate to the legendary level~" Tang En smiled mysteriously.

"ah?"

"Is the power of the heart also a rule?" Grace and Kana looked at Donn in surprise.

"Yes." Tang En nodded with a smile.

"The power of the mind is one of the most basic rules. Even the power of the mind is still included in the power of the mind. Think about it, if you can't think about it, is anything in this world meaningless to you?"

"It's meaningless to not think..." Grace and Kana opened their eyes wide and nodded slowly.

"Haha~, that's right. After you go back, you can notify other demon races to strengthen their mental strength, but whether the secret of the power of the mind is to you or not~" Tang En smiled and then flashed back to the witch tower.

"Hey, I was still confused by the demon pill back then. I didn't think about whether I would lose my will. I just regarded the rules of soul and flesh and blood as special forces, and no one told me that this is the power of the rule."

"It's my experience that Grace and other half-demons have even mastered the power of flesh and blood rules as soon as they entered the second stage. Now they have the power to teach them the heart..." Tang En sighed for a moment, then turned back to his dormitory.

After Tang En left, Grace and Kana discussed for a while. Considering that not every demon clan would have Tang En around to protect him when forming a demon pill, they finally decided to make the secret of the power of their hearts publicly available to the top leaders of the demon clan above level 3.

However, the demon clan is now intricate. After the secret of the power of care was released, the secret was not written into the demon clan's oath, and it spread in Qiaomuya's world soon.

At the beginning, the wizards only used the power of their minds as a supplement to the rules of mental power to speed up and strengthen the training of mental power.

However, when Paris accidentally taught the concept of the power of mind to his friend Ram, the Ram, who was struggling with the unknown path of cultivation, and the magic warrior who was suppressed at level 3 was extremely difficult to advance, was like a treasure. Ram, who had a strong will, was suitable for this path. Inadvertently, Ram initially developed the usage of the power of mind in the boiling blood world.

Later, in a competition with Paris, Ram sent out a regular-level mental power in the world of Jomuya for the first time. When a sudden explosion occurred, Ram beat Paris to dust.

The sudden emergence of strange rules in the Flesh Wizard Area not only alarmed Grace and Stina, but also attracted Tang En, who was basking in the sun on the roof of the City Lord's Mansion and waiting for food.

"Oh~, the rule of the power of the heart is revealed, it's very good~" Tang En looked at the white arrogance on Ram with a smile.

Tang En deliberately did not release the complete spiritual power cultivation system before, just to see if Qiao Muya's wizards could create their own cultivation methods. Unexpectedly, after 3 months, not only did Grace and other high-level half-demons not make any achievements in the spiritual power, but even the wizards also followed suit, learning the flesh and blood wizards to use the spiritual power as a new secret method to temper their mental power. In the end, it was Ram, a girl he forgot for a long time, who gave him surprise.

Thinking of this, Tang En looked at Grace on the side of her body with a smile. Grace immediately understood what Tang En meant, and her face turned red with shame.

"ha!"

At this time, Ram on the field roared, and the aura on his body instantly turned into ice blue. Then a sword light cut everything with the will to freeze everything, and swept fiercely towards Paris.

Paris was shocked. She had tried Ram's new rule attack with a forward momentum just now. Unexpectedly, at this moment, the opponent could actually superimpose this rule attack on the power of ice, which made her a little confused. So she could only turn on the 2nd speed burst to dodge.

The defensive array used for trial battles in "Kala" was shattered under the blow of Ram. Everyone except Tang En was shocked.
