There were not many dark crystals. Filson searched all over the cave and dug 8 yuan, but he seemed to be very satisfied with his expression.

"Well, this time it wasn't in vain. That guy, Copper Shield, would be very happy to see so many dark crystals." Filson clapped his hands and said.

"That... Master, I still have a chance to ask you for help. I don't know if it's OK." Seeing that Filson was in a good mood, He Feng asked quickly.

"Of course, you are my assistant." Filson nodded.

"Several guards in Shanjin Town also entered the mountain, but there was no news. Can you help me find them?" He Feng said.

"Those guards? Then I don't think there is any need to find them. They are just a group of laymen. How could they know the dangers in the mountains? If there is no news for a long time, it is probably impossible for them to be alive." Filson shook his head.

"Try to find them, even if they can find their bodies."

"Well... OK, I guess they must have followed the way in and they didn't walk far."

"Thank you, Master, then let's go to that section of the road to look for it."

There are indeed many benefits to following an old driver like Filson. Not long after they returned to the road at the entrance of the cave, they found a guard's body and found a suicide note on him.

Then they soon found the second and third ones, but this time the process became a bit dangerous. The carnivorous insects suddenly emerged from below, the poisonous spider, the sudden collapse of the ground, etc., all of which made He Feng bump into him. If Filson hadn't been there, He Feng would probably have to hang it several times.

"I guess they will be here at most. Do you still have to search?" Filson said to He Feng when he found the third guard body.

"This mountain is indeed dangerous... Thank you, Master, just find this." He Feng nodded.

"Yeah, go back."

Then he went out of the mountain and returned to the town. He Feng followed Filson to the private room of the Sapphire Tavern. Looking at the blood moon mine and dark crystals poured out by He Feng, Filson said: "You helped a lot this time. We should divide these ores equally, but I need dark crystals more. In this way, you get 3 dark crystals, and all of the blood moon mines belong to you. How about it?"

He Feng was shocked after hearing this. This Blood Moon Mine is 52 yuan. Is the value of the dark crystal so much higher than that of them?

But no matter whether He Feng was suffering or making a profit in this way, he admitted that he would never find these ores without Filson leading the way, so he nodded very simply and said, "Then let me listen to the master."

"You complete the mission [Dangerous Mountain] and gain 1500 experience points."

[Dangerous Mountain] This mission appeared after He Feng completed [Adventure Preparation]. The mission goal was to help Filson find the dark crystal. Unexpectedly, the experience reward would be so high.

"I like a kind-hearted guy like you. Let's do this. I will teach you a practical skill as a reward." Filson said happily.

"I believe there will be no better reward than this." He Feng said happily.

"Haha, a talking boy. Many ores contain gems, and what I want to teach you is how to find them and how to carefully extract them. First of all, there will be many cracks in ore containing gems and irregularities, such as...yes, this one." Filson picked up a piece of Blood Moon Mine and said.

He Feng first glanced at the ore in Filson's hand, and then looked at the other Blood Moon Mines, and found that the Blood Moon Stone in Filson's hand had indeed many cracks.

"Of course, not all gem-containing ores have such obvious cracks. Without cracks, you have to test the weight, observe the color, etc. You will not be able to teach you well in a while. When I finish this, I will tell you carefully. Then we will jump to the second step to get the gems out of the mine." Filson said, and took out a chisel and continued: "Gems are not as hard as you imagined. If you want to get them intact, you must be patient. Like me, chisel slowly according to the patterns. Don't be in a hurry."

Filson was very careful, which made He Feng sigh that life was really not easy.

About ten minutes later, Filson finally dug open the Blood Moon Mine and found that there was indeed a yellow gem inside.

"It's a piece of Ming jade, it should be sold for a good price." Filson carefully chiseled out the gem and said.

"So beautiful." He Feng sighed sincerely at the shining bright jade stone.

"There is always a unique beauty that has not been processed. Unfortunately, most people don't understand it. In addition, there are also gems in this and this Blood Moon Mine. You can keep them first and teach you how to chisel them when I come back." Filson picked up two Blood Moon Mine and said.

"Okay, I will hold them away." He Feng nodded.

"Then let's get here. I have to go out and do something. In three days, you can find me at Cabin No. 36 in the West Side." Filson said and pushed the door open and went out.

When Filson left, He Feng's Dark Crystal and Blood Moon Mine were put into his backpack and walked towards Ragren's hut.

"Sir, I'm back." He Feng shouted, knocking on the door of Ragren's cottage.

Soon, the door was opened. "Did you find them?" Ragren asked anxiously behind the door.

"Sorry, sir, I found three of your men, but they have all died. This is the suicide note I got from two of them." He Feng handed the two suicide note to Ragren.

"Oh no... it's all my fault." Ragren shouted with great pain after taking two suicide notes.

"Please settle their family." He Feng sighed.

"I can do it, please come in and sit down first. Thank you for bringing them back to me."

When the two of them sat on the sofa together, He Feng looked at Ragren who was still in sadness and said, "Sir, I have found the black crystal you want me to find, please take a look." After He Feng said that, he took out the dark crystal and handed it to Ragren.

"It's really a dark crystal! I really can't believe how you found it!" When I saw the dark crystal, although Ragren's tone was still sad, his tone was extremely surprised.

"It's all up to Master Filson to find it. The mountains are really too complicated."

"He actually gave you a piece. It seems that he admires you very much. You have helped me a lot this time." Ragren said while patting He Feng's shoulder.

"I wonder what the use of this dark crystal... is?" He Feng couldn't help asking curiously.
