"Bang!!!"

Yin Yu suddenly threw a large coffin that was corroded and rusty to Lin Feng. Lin Feng, who was reading a book in the study, was startled by the sudden coffin, pointed at the coffin and shouted:

"What is this?"

"This is the reward for this upgrade." Yin Yu said, holding the coffin.

"I don't want this kind of reward! I don't want to use this thing so early!" Lin Feng said angrily.

"It's really a blessing that I have prepared carefully for a long time. At least I can open it and take a look." Yin Yu said with a pout.

Lin Feng gritted his teeth and uncovered the lid of the coffin and put it aside. A gust of yin energy instantly overflowed from the coffin. In the coffin, a skeleton that had been dispersed was lying quietly at the bottom of the coffin, which seemed to have a history of at least several hundred years...

"Yinyu... Such a bad thing, do you think it's a reward? Are you teasing me? - Then again, you didn't dig someone's tomb somewhere, right..." Lin Feng said with a chill when he looked at the bones lying at the bottom of the coffin.

"That's right, through intelligence analysis, I locked an ancient tomb and dug it open. This ancient tomb is not a tomb for ordinary people, but the tomb of a legendary sword saint, a senior of Dugu family. In order to find his tomb, a bloody storm broke out in the world, but in the end no one found it, but instead made me a bargain." Yin Yu said holding the coffin.

"Yin Yu... But this is too...stimulating, isn't it? Besides, digging people's ancestral graves will be punished by God..." Lin Feng's back felt cold.

"I specifically checked the information. Senior Dugu has no offspring, and descendants of blood relationship do not exist, so it is not considered digging people's ancestral graves."

"...This is not a place to complain about?" Lin Feng said pressing his forehead.

"Master, I know that doing this is indeed a bit selfish, but I checked the information and found that this senior Dugu is known as the Sword Saint, with extremely high martial arts skills. He created a peerless sword technique. In order to prevent the sword technique from falling into the hands of the killer, senior Dugu buried him together. Although there were similar sword techniques in later generations, it was just some fur. Here is the real secret treasure..." Yin Yu pointed to an iron box pillowing under the skeleton and said.

"Then why don't you take the iron box back, but just move the coffin back?" Lin Feng raised his eyebrows.

"I originally planned this, but after digging the tomb, I found that this bone was not an ordinary bone..." Yin Yu suddenly said with a serious expression.

"What else can there be different bones? Even if this is the bones of the sword saint, it is just a bunch of bones."

As he said that, Lin Feng picked up a bone in disgrace and weighed it, his face suddenly changed.

"No...the bone...the weight is wrong."

"I really didn't notice this." Yin Yu said in surprise.

"When I was in high school, in order to make money, I did grave relocation work for the Municipal Axe funeral office during the summer vacation. Naturally, I was the one with the least experienced one doing the dirty work of cleaning up bones. So I knew that the weight of bones should not be so heavy..." Lin Feng said with a narrowed eyes.

"I'll detect it."

Yin Yu closed his eyes and entered the search state. After a moment, he opened his eyes and said:

"Master, after searching, the bone density of these piles of bones is no different from that of ordinary bones. But what made me feel wrong is... the luster of these piles of bones, because of this luster, I chose to bring it back."

"What luster?" Lin Feng asked hurriedly.

Yin Yu walked to the window and pulled the curtains up, and the room suddenly fell into darkness. Yin Yu picked up a bone and handed it to Lin Feng, saying:

"Did you see it now, Master?"

"See...I saw!"

Lin Feng shouted in surprise. He saw that the surface of the bone was covered with a light blue fluorescence, which was very weak. If it were not for the dark environment, there would be no abnormality at all.

"Can this be a substance like phosphorus?" Lin Feng said with his bones down.

"I have conducted a comprehensive analysis of this pile of bones. It is certain that it is definitely not phosphorus. If I can't search, it means that it may be a special substance that is not recorded in the archives..." Yin Yu pondered.

"Anyway, let's move this iron box out first."

Lin Feng sighed and bowed to the bones:

"Senior, I offended you so much, don't be surprised..."

As he said that, Lin Feng moved the skeleton aside, carefully moved out an iron box pillowing under the skeleton, and brushed away the dust on the surface. A big lock was put on the iron box, and Lin Feng injected a trace of force into the iron lock, and the lock core of the iron lock made a crisp sound, which broke in response. Lin Feng quickly opened the box impatiently.

In the box, a silk cloth soaked in oil wrapped around things and attracted Lin Feng's attention. Lin Feng carefully removed the silk cloth, and several thin iron plates appeared in the silk cloth. On the iron plate, there were shallow patterns and words engraved...

"This is a rubbing. Apply ink on it and then cover it with white paper to get the rubbing!" Lin Feng, who was sharp-eyed, could see what it was at a glance.

"There is no need to be so troublesome. I can read all the knowledge above and use the synesthesia between us to pour into your brain. Activate the scanning function and start reading the data. After reading, is it transmitted now?" Yin Yu asked.

"Transfer now." Lin Feng nodded.

“Buzz.”

Lin Feng only felt his head blinded and his eyes darkened. Because he forced too much information into it, Lin Feng only felt a little hurt and a little dizzy, and he felt a disgusting feeling, as if he had to vomit it out. Looking at the countless information in front of him, Lin Feng, who felt dizzy, quickly blinked a few times before turning off the information and breathed a sigh of relief.

"How does it feel?" Yin Yu smiled.

"Not very good. So, what should I do with this sword saint bone?" Lin Feng shook his head, picked up a bone and said.

"How about burning?"

Suddenly, Hongyu appeared uninvited in front of Lin Feng.

"What, you mean, burn this bone with fire?" Lin Feng frowned.

"Hmph, the common people are common people, and they are not at all enlightened. You can only burn it to ashes with ordinary flames, but if you use my original power to burn it, you may know the secret hidden in it!" Hongyu slowly walked to the edge of the coffin, stared at the bones emitting blue fluorescent, and whispered.

"Really? That's great, let's try it!" Lin Feng said anxiously.

"But if there are any consequences, I'm not responsible."
