Lin Yu's skills are indeed very agile. In less than a stick of incense, he picked up his feet and jumped all the way to the back mountain.
"This is the back mountain of this city, go up now!"
After saying that, Lin Yu jumped up again, his feet rushing towards the top of the mountain as if riding the wind.
"No wonder this place wants to build this secret warehouse. Once forced to go this way, without this secret passage, I'm afraid it will be a dead end!" The old man also understood the reason for building this secret passage.
After Lin Yu reached the top of the mountain, he carefully observed the surrounding situation. After thoroughly confirming that there were no outsiders nearby, he put down his guard and prepared to attack the five marks with the old man.
"Teacher, let's start!" Lin Yu whispered.
'Well..., this place is perfect. "The old man is also very satisfied with the place Lin Yu found.
"It's still the same as when you attacked the two marks before. You need to concentrate your mental power in your heart first. Because this time we are attacking the five marks, the attention you need cannot be distracted for a moment, otherwise you will go crazy. , no one who comes can save you." The old man reminded Lin Yu again and informed Lin Yu of the danger level of this matter.
"Don't worry, teacher!" Lin Yu lowered his eyes and replied calmly.
After that, Lin Yu put away the things he had prepared before, one by one, sat cross-legged on the ground, stood with both hands, condensing all the source energy and spiritual power around his body.
"Boy, you have to hold on!" The old man was also worried about Lin Yu in his heart. He was very aware of the danger Lin Yu faced this time.
For a moment, Lin Yu's entire body was enveloped by his own origin energy. What's a bit disappointing is that Lin Yu's forehead is already covered with sweat at the beginning.
As time passed, the source of energy on Lin Yu's body became more and more concentrated. This force also made Lin Yu's body a little frightened, and Lin Yu's body began to tremble.
"Boy, this is just the beginning, hold on!" the old man reminded kindly.
After that, Lin Yu also felt that in the entire sea of mind, countless source energy was moving wantonly towards one place.
"Okay, this is the state. You need to stabilize it first!" the old man said.
Lin Yu did as he was told, only to see that the trembling frequency before that was getting less and less.
"Okay, in that case. I'll start breaking open the elixir right now." After the old man confirmed that Lin Yu had stabilized, he responded immediately.
In the sea of mind, the old man created a force directly towards the place where the elixir was.
The power effortlessly absorbed the elixir and suspended it above the sky, directly above Lin Yu's forehead.
After that, he cast a spell to lift up the dew and dropped a few drops on top of the elixir.
The yellow elixir was irrigated by the dew, and seemed to lose its ability to resist in an instant. The yellow color on the elixir gradually receded, and the entire volume became much smaller than before.
"Ha..., little thing!" The old man also smiled when he saw this.
After that, after the yellow elixir completely faded away from its previous body, the old man quickly used his mental power to control the stone hammer.
The stone hammer was also controlled directly above and stopped towards where the elixir was.
"Okay, this will completely break your body!" The old man's old voice sounded again.
After that, the old man once again released his spiritual power, dispersed part of his spiritual power and injected it into the stone hammer, and struck the elixir with a hammer.
The stone hammer was controlled by the spiritual power, but it was completely different. One hammer blow directly caused the elixir to completely lose its ability to resist.
The elixir was bombarded by spiritual power and finally shed the body that was wrapped around it. In the end, only a small piece of black magic crystal was revealed.
"This is it!" The old man was very satisfied when he saw the final product, and he completely confirmed his previous guesses about this thing.
"The finished product of this magic crystal... is really good!" The old man waved his spiritual power again, and the stone hammers and dew that had been floating in the air happened to avoid Lin Yu and were scattered on the ground.
But only that small piece of magic crystal was still suspended above Lin Yu's forehead.
"Boy, now we have to use this crystal to absorb it!" The old man looked at Lin Yu who was gradually struggling and said with some worry.
"Teacher..., I'm ready!" Lin Yu's voice was hoarse, and it was obvious that he was struggling to gather his mental strength.
"Okay, you have to hold on!" the old man also shouted loudly.
After that, the old man once again injected his spiritual power into the magic crystal. But what is different from before is that this magic crystal directly mutates after absorbing spiritual power.
This wasn't over yet, the old man gave another strong blow, as if he wanted to use his spiritual power to force the magic crystal open.
"Break it for me!"
After that, the magic crystal couldn't bear its power and exploded into dozens of black fragments, scattered on Lin Yu's forehead.
What's even more surprising is that after the fragments were scattered around Lin Yu's forehead, they seemed to be absorbed by the latter.
Several fragments disappeared in an instant.
"Boy, now that the power of this magic crystal has been absorbed into your heart, all you can do now is up to you!" the old man said.
"Understood!" Lin Yu shouted through gritted teeth.
"When these fragments first entered the sea of heart, they would definitely be repulsed by them. Trying to calm down this abnormal movement is the beginning of the real pain." The old man did not speak anymore, for fear of disturbing Lin Yu's mind, so he had to say it in his heart He read silently.
Lin Yu also sensed the pain that the old man mentioned before, and Lin Yu's expression instantly became ferocious.
Lin Yu only felt that his heart was completely rioting. For a time, countless sources of energy and spiritual power were constantly fighting against the fragment. And every blow caused Lin Yu to feel extreme pain, which was far worse than the punishment of being cut into pieces with a thousand knives.
"Ah..., damn..., ah..." Lin Yu tried not to make a sound, but the pain was really unbearable.
"Boy, gather your mental strength and don't let this strange movement completely disrupt your mind!" Seeing Lin Yu in extreme pain, all the old man could do was to keep reminding him.
"Ah..., it hurts!, ah..." Lin Yu kept making muffled sounds.
For a time, the source energy, spiritual power, and magic crystal were all mixed together, making it difficult to calm down.
Lin Yu had already lost consciousness at this time, and his entire face turned pale.
"Boy! Hold on!" Lin Yu felt that the old man's words were becoming more and more blurry, and his own hearing seemed to be affected by them.
"Ha..., Lin Yu, Lin Yu, are you really going to stop here today?" Lin Yu laughed at himself in a blur of consciousness, letting the strange movements devour him bit by bit.
