Facing Xia Feichi with a sincere face, Lin Feng had to smile bitterly and nodded, put the crystal in his pocket, but accidentally put it together with the pocket watch. Suddenly, the pocket watch made Lin Feng's face change...

"What's wrong, Yin Yu, calm down." Lin Feng frowned and said.

"No, the energy fluctuation is too great, which has seriously interfered with my operation. Master, please put it in another pocket and put it alone. If it is placed directly in the engine space, the engine may be disintegrated due to violent energy fluctuations..." Yin Yu said seriously.

"!"

Lin Feng's heart twitched violently, and quickly took out the paper bag and replaced it in another pocket. The violent tremor of the pocket watch finally stopped.

"Yinyu, what is this crystal? Why is even you so afraid?" Lin Feng asked quietly.

"Because I'm sure this crystal is the purest energy body in this world - the soul crystal!" Yin Yu said firmly.

"Soul Crystal?" This unfamiliar word made Lin Feng a little confused.

"That's right, it's the soul crystal. The soul crystal will only appear in certain specific places, that is, where the origin of the spiritual essence is hidden. This spiritual essence is the beginning of all life and consciousness in the world, and it is also the most important material for making the angel engine. It is said that it appears once every ten thousand years. There are no more than five places where the spiritual essence is hidden in the entire world, so it is extremely rare. If a soul crystal appears, it means that the spiritual essence must be nearby!" Yin Yu said anxiously.

"The origin of the spiritual world? The material for making the angel engine? The beginning of all life and consciousness?"

Lin Feng blinked in shock, and after a moment, a trace of shock surged on his face:

"Could it be... this thing is what Ling Yueyong and Huaxia Zhengfu have been looking for...a thing that has been resurrecting the dead?"

"It is very likely. Huaxia Zhengaxao hopes to create a copy of the Angel Engine by finding it. To take a step back, even if they can't make the Angel Engine, they can still create immortal soldiers in batches through Yunling Origin. Think about it, if there are immortal soldiers in Huaxia Zhengaxao... then who else will be their opponent in the whole world? This is why they repeatedly indulge you and let you out of prison - they are using you!" Yin Yu also said to himself with some shock.

"So that's it... No wonder even the three generals of the Army are so concerned about this mysterious thing. It turns out... they are playing such a dangerous game of chess..." Lin Feng was also shocked and murmured.

"Master, now it's also certain that what saved Lin Xier is the origin of the spiritual world. If you get it, Lin Xier's condition will be completely cured.

"I might as well make a bold inference. The so-called "Shennong Yaoshu" that can bring people back to life is actually a spiritual source possessed by Shennong in ancient times. It has been passed down from generation to generation and has been passed down to this day. The person who was once locked up in the water prison of the lower courtyard was once detained in the upper courtyard and Jiuzhang Island, so he hid the spiritual source on Jiuzhang Island. Later, he was detained on Xiayuan Island. He left clues about treasures in the dungeon. He didn't want to be obtained by the master. I originally believed in science and did not believe in the will of heaven, but now I see it, it is the will of heaven, the will of heaven..." Yin Yu murmured.

"The truth is like this..."

After listening to Yin Yu's inference, Lin Feng felt a little creepy in broad daylight. He had been pursuing the truth, but now the truth is in front of him, which is so shocking. If Lin Feng had not come to the Lower Court Island, he would not have been locked up in the confinement room, and if he had not been locked up in the confinement room, he would not have been tampered by the dead mouse. If he had not been tampered by the mouse, he would not have demolished the rat hole. Without demolishing the rat hole, he would not have found the key information about the treasure. Without the key information about the treasure, Lin Feng would not have tried so hard to enter the intermediate court. If he could not enter the intermediate court, Lin Feng would not have been able to buy this soul crystal, and he might never know the truth of the matter.

In this interlocking process, as long as one link is missing, Lin Feng will shift his target. Lin Feng has really walked through it all the way. I have to say that this is indeed terrifying enough. I am afraid that it can only be described as God's will...

"Yinyu, you said that the origin of Yunling is the most important material for making an angel engine, right?" Lin Feng shook his head and dispelled his random thoughts and asked anxiously.

"Yes. To make the angel engine, you must use the origin of the spirit and a living girl. This is a very terrible ceremony, very cruel and very **... But I can't think anymore, I always feel my head hurts, and this part of my memory... seems to be damaged." Yin Yu's voice became painful.

Lin Feng swallowed a mouthful of saliva. The origin of the angel engine must be used to make the Lingyuan and a...a living girl? So, Yin Yu is not an illusory human form made by a computer, but a young man who once lived in the world...

"Hey, Lin Feng, what are you thinking."

Just as Lin Feng was thinking about going in an increasingly terrifying direction, he was suddenly slapped heavily from behind. Lin Feng, who was interrupted by his thoughts, almost jumped up in fear. When he turned around, he found that it was Ling Yueyong, Zhang Liqiang and Xiao Bing.

"Yueyong? Why are you here too?" Lin Feng calmed down and asked with a frown.

"You're still saying that. You're really right. Why did you go up the mountain alone? What should you do if you encounter danger?" Ling Yueyong also frowned and said with great dissatisfaction.

"What danger can I have? But you are really here. Isn't anyone causing trouble for you?" Lin Feng shrugged and said without objection.

"There are, but there are, but they have been cleaned up."

Ling Yueyong pointed to the card on his chest, and a bright red "1684" appeared in front of Lin Feng. The cards on his chest of Zhang Liqiang and Xiao Bing also became more than two thousand, and it seemed that he had experienced a battle.

"I met a few people who met on the road and cleaned it up. Xiao Bing and Li Qian also helped, so our rankings changed. - Your rankings have also risen by 600 places. Are you going to cause trouble again?" Ling Yueyong glanced at Lin Feng's chest ranking and frowned.

"Hey, sister, why do you beat people just to get rid of the people who are chatting with me? I hit people just to cause trouble? Only the state officials are allowed to set fire and not the people are allowed to light the lamp!" Lin Feng said with some depression.

"This... in short, you are too likely to cause trouble. If you don't look at you carefully, who knows what trouble you will cause?" Ling Yueyong said dissatisfiedly.

Lin Feng shrugged without comment. He still agreed with this.

"Where are we going next?" Ling Yueyong asked.
