The old man waved his hand, and the scene in front of him changed. He saw only a fifty-foot radius where Lu Yi stood, a piece of scorched earth, while the rest of the area was not affected at all by the scenery of mountains and forests.

"This is one of the characteristics of my Heart Mirror Array. It can confuse your mind and simulate the scene you imagined in your mind. If I guessed correctly, you just wanted to use the array to find out the array.

Where are the eyes?"

"Yes, this junior should have destroyed a thousand feet radius just now."

"Haha, actually, the core of this formation is me. I learned your purpose through your arrangement of the Four Symbols Thunder Fire Formation, so I let the phantom formation simulate the scene you wanted. In fact, you have been spinning around in circles and you have never done it.

Take a step away." The old man explained.

"I just deployed so many four-elephant thunder and fire arrays, where did the energy impact go?" Lu Yi asked in confusion.

"There is an energy-absorbing array nested within the Heart Mirror. It can absorb 40% of the energy generated by you when you break the array and use it to circulate the energy endlessly. This is its second characteristic."

"Isn't this array impossible to break?" Lu Yi asked.

"Actually, it has a third feature, which is the most powerful thing about this formation. It can launch spiritual attacks. It allows the people in the main formation to see something deep in your heart and directly attack your most vulnerable place.

."

"Similarly, this formation has a fatal flaw, which you should be able to guess." The old man further explained this strange formation.

"Array heart?" Lu Yi thought for a while and asked.

"Yes, the heart of the formation. Because the heart of the formation is the controller of the phantom formation, the mental power of the main formation must be extremely strong, because it consumes mental power. The level of the heart mirror formation is based on the main formation.

It comes from the level of mental power of the person. As the center of the formation, if his mental power is lower than that of the person entering the formation, his attempt to imitate the thoughts of the people entering and exiting the formation will be seen through by the opponent.

It suffered backlash, and at this time, this is an ordinary phantom formation. The same formation, if I preside over it, can reach the fourth to eighth level, but if you preside over it, it will only reach the fourth level."

"How are you? Are you interested? Do you want to learn?" The old man explained in detail.

"Please give me some advice, senior!" Lu Yi was overjoyed upon hearing this. This opportunity is really rare.

"Haha, okay, I will teach you how to set up the formation now, but you can only learn to memorize it now, but you can't set it up, because this formation cannot be set up with talisman materials, and the minimum requirement is a fourth-level formation mage, so come on,

baby!"

For half a day, the old man explained to Lu Yi the layout of the "Heart Mirror" in detail, how to use it, and how to change it. Lu Yi kept it in mind one by one. Since he couldn't practice it, he could only leave it to be verified one by one later.

Soon, it was approaching dusk. The old man looked at Lu Yi and said kindly: "Baby, do you know why I taught you this formation?"

"Junior doesn't know, so I ask senior to tell me. However, I believe that there is no free lunch in the world. The old man who taught me the formation must have something to do with me, right?!" Lu Yi was honest and directly expressed his inner thoughts.

.

"There used to be one reason, but now there are three. Let me start with the simplest one. You are Jin Dongzi's apprentice. Jin Dongzi is somewhat destined to me. So, even if you have benefited from your master, of course,

This is not the original factor. Secondly, I, a junior, have accepted your affection, and I will continue to cause you trouble in the future. This is the original reason. Thirdly, and the most important point, you

Be sure to remember it and don't reveal it to anyone, otherwise it will be a disaster for you! That's why I didn't call my junior here now because I want to tell you the third reason first. This piece of jade on your neck

"Let me ask you, do you know its origin?" The old man said a lot in one breath.

Lu Yi looked confused. He was obviously shocked by the old man's words. He didn't expect that the old man could easily detect the things close to his body. He picked up the silver lock on his neck from his underwear with both hands and looked at the ancient jade in the middle.

He said: "The younger generation only knows that this is an item passed down from my mother's family. It has been in my hands for a long time and I don't know how many generations ago. Our ancestors only said that this is a lucky thing and there will be a chance, but no one has ever encountered it.

"

"Opportunity, haha, it's not bad to say it's opportunity, but there's something more important, but it's responsibility." The old man smiled.

"Responsibility?" Lu Yi frowned.

"Well, responsibility, of course, you may not encounter this responsibility in your life, maybe it will come tomorrow." The old man said meaningfully.

Lu Yi was confused when he heard this, and he hurriedly bowed and said: "Please ask my family to help clarify this kid's doubts."

"Do you know what the devil said?" The old man twirled his beard with one hand and asked, looking up at the distant sky.

"This junior has seen some records in the Shu Jue Pavilion in Yaoshan Mountain. They are some allusions about ancient times. It is said that there were demons who invaded our continent in ancient times, but were defeated in the end. The rest is not clear."

"Yes, this happened tens of thousands of years ago. My ancestors participated in that cross-continental war. It was also that war that resulted in the loss of all the elites of the human and demon tribes, and the ancient true spirits were almost extinct.

.This piece of jade on your neck is the key to the victory of our human and demon tribes in that war. It is the core of the peerless formation that was forged with the hard work of your top human formation masters and the four true spirits of the demon tribe.
