• Both boxes required exclusive fingerprints to unlock. After that, Old Hai handed the two boxes to a servant, whispered a few words to him, and then the man walked out with the box. Ten minutes later, he took the box that had been opened and put it in front of Old Hai.
• Fu Yan was not surprised when he looked at the opened box. After all, they could kill people at will here, so what could they not do?
• Hai Lao's eyes lit up and looked at the two boxes, and he took out two identical keys from them. The details were very good, and it was impossible to tell which was true and which was false. It can be said that it was a lot of effort.
• He picked up the key and used the magnifying glass to see no effect, so he could only try it.
• 

  hailao

  Come with me.
• Hai Lao picked up the key, glanced at him, got up and said.
• Fu Yan looked at his back and sighed, then followed.
• The two of them came to another room, both outside and inside, unremarkable, until he saw Old Hai just lightly touching the floor, and a secret passage soon appeared on the ground.
• After entering, it was a place similar to a laboratory, surrounded by some instruments, and many containers were also filled with venomous snakes and body parts of people soaked in formalin. It looked very retching.
• Fu Yan quickly turned his eyes and felt very uncomfortable in his stomach.
• Hai Lao glanced at him lightly and didn't speak, and continued to walk in until they came to a door made of crystal, where they stopped.
• 

  hailao

  Here you go.
• He handed Fu Yan the key in his hand and looked at the door as if he was recalling.
• 

  hailao

  This is where your father used to study, but we can't open it no matter what method we use. Later, we learned that it needs an exclusive key, and only this key can open this door.
• Fu Yan looked down at the thing in his hand, no need to ask, it must be this one.
• 

  fuyan

  Want to open it?
• 

  hailao

  You go, after all, you are his son.
• Hearing his words, Fu Yan frowned in disbelief. He did not believe that this old man would be so kind.
• 

  fuyan

  What's in there?
• 

  hailao

  I don't know, that's why I desperately want to open this door and see what's inside it!
• As soon as Hai Lao was excited, his face turned red, and the crutches in his hands were a little trembling, and he felt like he could fall down at any time.
• Fu Yan wanted him to die, so he didn't have any sympathy. After hesitating for a while, he still felt that opening this door, not only Old Hai was curious, but he was also curious about what his father left behind.
• After the first key is inserted, it can't be turned no matter how you twist it. This is wrong.
• So he inserted the second one in, but the result was still the same, and he couldn't get it anyway. Elder Hai watched Fu Yan push aside and drove by himself, but there was no movement from the mission either.
• 

  hailao

  How could this be...
• Hai Lao's face turned pale and he started the key in his hand, but the sudden explosion threw it to the ground fiercely, and he kept stepping on the key with his feet like crazy, as if he wanted to vent all his anger on it.
• Fu Yan quietly stood by and watched the madness, without any intention of stopping him. His eyes were extremely cold, and there was still irony in his eyes.
• In the end, Hai Lao finished his fire, and he couldn't help but fall to the ground and gasped for breath, looking very embarrassed.
• After living for a while, he regained his senses and glanced at Fu Yan viciously, his face hideous.
