"Don't you understand, according to the way I said, mobilize the energy in the body to make it compressed!" Donald kept knocking on the ground with his magic wand, and shouted at Jia Zhengjin with a depressed face, "No matter what kind of energy, only you can successfully mobilize it!"

"I've tried more than a dozen times, but if it doesn't work, it won't work!" Jia Zhengjin sighed, "Forget it! This skill is completely unsuitable for me, and I can't learn it anymore!"

"Why don't you kid have any ambition at all?, you can't learn such a simple thing?" Donald said unhappily, "Lift my spirit, understand and master it well! Do you know how many people want me to teach them magic, and I don't bother to pay attention to it? If it weren't for the fact that you had to give me a space prop, this person is too favorable, I wouldn't have taught you my lifelong comprehension!"

"I don't want to learn it at all? And what I can learn can be mastered in just a second, and I don't need to be so troublesome!" Jia Zhengjin sighed, "I'm really in a hurry, can I ask to let it go?"

"What I Donald said, there will be no discount! If you don't learn it today, stay here honestly! Practice in front of me until you master it!"

"If you can't learn, you can't learn, no matter how hard you force me, it's useless!" Jia Zhengjin showed a bitter gourd face. If it weren't for the fact that he couldn't beat the other party, he would have gone crazy a long time ago!

"Don't talk nonsense! Use your brain to understand what I mean! How to compress the energy, how to use the compressed energy flexibly, it sounds simple but the operation is very difficult! The slightest mistake will lead to failure, you must make no mistakes!" Donald's magic wand slammed into the ground, "Hurry up! If you are really in a hurry, you should act immediately!"

"Even if you say that, I'm just a waste wood otaku who is addicted to games! I'm not a top student! I'm not the kind of young man who is so smart that he has no friends! I really can't understand the principle you said!!" Jia Zhengjin was forced to be so anxious that he couldn't help blurting out.

Then he was stunned and immediately closed his mouth.

"Waste otaku?scholar?pretending to be a young man?" Donald looked confused, "What's that?"

"Master Peyton, it's hard for your subordinates to understand!" Olivia whispered beside her.

"Forget what I just said!" Jia Zhengjin felt very embarrassed, as if he had been forced to such a situation for the first time since crossing into this world! Fortunately, people couldn't understand his professional terms, at least he could still be confused.

Donald didn't understand what Jia Zhengjin meant by the words, so he continued to repeat the principle of magic compression several times: "In the final analysis, although the essence of other energies and magic is different, there should be no difference in compression! You still haven't mastered the essence, you must find the key as soon as possible! What is the mistake in the end, if you don't find it, you will never be able to learn!"

"So I don't want to learn at all!" Jia Zhengjin said hurriedly, "Can you let me go?"

"What I've said, I won't compromise it!" Donald's expression turned cold, "Don't get out of here until you fully understand!"

Hearing this, Jia Zhengjin felt hopeless.

The system hasn't prompted anything so far, so it's estimated that this teaching method is ineffective, right? After all, I can't open the magic skill book at all, and as for the combat skills, I also need equipment or skill books. Maybe if you want to learn skills, you can only use the skill book, and you may be limited by the system......

But the dead old man Donald just refused to let go, forcing him to repeat the practice over and over again, and before he knew it, a long time had passed.

I don't know that after practicing hundreds of times, Olivia has closed her eyes and fallen asleep in a daze when she lies next to the stunned eagle.

I don't know if the system is pitiful for Jia Zhengjin, and finally when he was so tired that he was about to lie down, a voice like a savior sounded.

You have learned the universal passive skill [Energy Compression] taught by Donald Higgins!

[Energy Compression] Passive skill. It can compress the special energy contained in the body and apply it to any active skill. The stronger the compressed power, the more powerful the skill will be!

When he saw the new general skill appear in the skill bar, Jia Zhengjin cried with joy.

It seems that the system has not given up on itself, and it is a miserable thing to be left here by this old man. If you delay a lot of time and can't return to Holy Dragon City in time, not only will you be depressed, but your family will also have to worry!

Thinking of this, he immediately shouted at Donald excitedly, "I succeeded! I finally succeeded! Can you let me go now?"

"Oh?" Donald's eyes flashed with anticipation, "Have you finally learned? Or did you deliberately deceive me in order to leave?"

"What am I lying to you for? Jia Zhengjin raised his hand, "I've really learned, 100 percent!"

"Then use it once and show it to me! If you really learn it, even if you return your favor. Donald's wand pointed at the nearest tree, "Feel free to attack it with your skills." ”

"Wait!" Jia Zhengjin glanced at the skill bar suspiciously, "But this is a passive skill, how should I use it?"

"Passive...... What?"

"Oh, it's nothing!" Jia Zhengjin hurriedly shook his head, "How can I use energy compression in combat skills?"

"What? can't you do such a simple thing? How bad are your qualifications?" Donald looked depressed, "It's good that you're not my student, otherwise you'd be as your teacher." You're too stupid!"

"You don't have to teach me, think I want to learn?" Jia Zhengjin glanced at him, "What does my poor qualification have to do with you?"

"Don't talk nonsense!" Donald said helplessly, "First of all, when you release magic or combat skills, you must first accumulate energy, right? If you really master this compression principle, try to mobilize more energy, and then compress its volume to the amount of energy that would otherwise be needed to release the skill......"

"Accumulate energy?" Jia Zhengjin is not so troublesome to release skills, basically the selected skills can be used automatically. I don't know if I can do it successfully? According to what Donald said, it's actually a skill that doesn't let go after selecting it, just like holding down the left mouse button when playing the computer, so that the character can concentrate his energy, right?

Although in reality, I may be different from the game character, and there is no mouse to press, but the principle is the same, right?

Thinking of this, Jia Zhengjin selected the cross cut from the skill bar.
