Seeing Zou Yi's nervous look, Lu Shan smiled and said, "Senior brother, please rest assured. I have checked it before. This silk is very reliable and cannot be broken."

As he said that, his wrist trembled slightly, and the two meters square silk had been spread lightly on the tabletop.

"This square silk is two meters square, which just matches the size mentioned in the rumor. Let's look at this..."

But he saw him take out a piece of black silk as big as a palm from the monk's robe again, and put it carefully on the side of the white silk as if it were treasured.

"What can you tell these two pieces of silk?"

After the small piece of black silk was placed on the table, Lu Shan did not continue to say it, but looked at Zou Yi and asked back.

After he asked this, Zou Yi became interested and immediately took the two pieces of silk in his hands and touched and looked at them carefully.

"From the material point of view, these two pieces of silk should be made of the same silk knitted, but the white piece is slightly more delicate in needlework than the black piece, so it feels smoother to the touch."

Before Zou Yi could continue to speak, Lu Shan had already taken over and said, "These two pieces of silk are indeed made of the same material, which is the silk of the polar fire silkworm. The polar fire silkworm lives in the underground magma. If it were not for the means of the heavenly being able to capture it, the ancestor accidentally discovered a large group of polar fire silkworms inside a newly erupted volcano, and brought them back to the Yin-Yang Taoist Sect to carefully cultivate it. Since then, all the inner disciples of the Yin-Yang Taoist Sect have worn clothes made of this kind of silk. The ordinary swords made of this silk cannot be damaged by a single piece, and it has the effect of avoiding fire, which shows its preciousness. It can be said that before the Taoist Sect was destroyed, this silk could only be seen inside the Yin-Yang Taoist Sect, and it could not be found outside."

"The blood on this?"

Just the moment Zou Yi picked up the black silk, he found that the silk was slightly hard, and there was a faint blood-red color in the black. Now, hearing what he said, his heart couldn't help but tremble.

But when Lu Shan held the black silk in his hand again, he sighed: "Those Taoist guardians rescued an inner disciple back then. They were still unable to survive because they were too seriously injured. This silk is a piece of his clothes back then."

Even if he did not visit that battle in person, Zou Yi could still feel how tragic the scene was through the other party's previous and subsequent narratives. More than 300 inner disciples and nearly 2,000 outer disciples fell in one battle. What kind of scene was that? Purgatory on earth was nothing more than that.

After a long time, Lushan returned to peace and continued, "So from these two points, this piece of silk is definitely the letter left by the ancestor."

"really"

For a moment, Zou Yi was also convinced by his words, frowned and pondered: "But if this silk is really the letter left by the master, why is it empty and there is no handwriting?"

“This is not difficult to explain”

Lu Shan smiled and said, "In the world of cultivation, letters are not written with a pen, but are infusing information into objects through spiritual consciousness. For practitioners, it is more convenient to transmit information in this way, and it is more confidential under the action of spiritual consciousness."

"I see"

After hearing what he said, and remembering the mark that Zou Yan left in the flute before, Zou Yi suddenly realized.

"How should we see the content of this letter?"

I have to say that at this moment he had already developed a strong interest. If the content of this letter is as Lushan said, it would be profitable.

"I don't know this either. In theory, only if both parties keep this letter, they know how to interpret it. If you want to crack it forcibly, the information left in this silk will completely disappear."

Seeing Zou Yi's look of loss, Lu Shan then smiled and said, "Don't you hurry to talk about these things first, it's not too late to say it when you determine whether this silk is the rumored letter."

“How else do you need to be sure?”

Zou Yi looked puzzled. He said that the material is the same and the size is the same. Besides, he cannot determine the content of the letter, so how should he determine this thing?

"Senior Brother Zou thought that our lineage only shouted slogans and did not do things in the past few thousand years, right?"

After making a joke, Lu Shan didn't mean to be flirting with his appetite and immediately explained: "You think, if it was the letter from the ancestor, then there would naturally be a trace of yin and yang spiritual power fluctuations on the silk. As long as you can confirm that there is indeed fluctuations in the letter, will this problem be solved?"

"That's how..."

Zou Yi shook his head and smiled bitterly: "If this is really effective, then I can tell you now that this letter was not left by the master."

It is naturally not groundless that Zou Yi dared to make this judgment so sure, because he had investigated this silk before and did not feel any fluctuations in the yin and yang spiritual power.

"Senior brother, don't rush to make a judgment first"

Lu Shan obviously didn't take his decision seriously and smiled: "This kind of spiritual power fluctuation cannot be seen casually. If it were so simple, this silk would probably have been taken first."

Zou Yi said in confusion: "Is there any special method?"

"There is no method"

Lu Shan smiled mysteriously and said, "But there is something that can easily recognize this kind of spiritual power fluctuation."

Without waiting for Zou Yi to ask questions, he continued: "It's the inner disciple's token."

"Don't this thing be lost with that war?"

As soon as he said that, Zou Yi thought of something, and nodded after understanding, "The token in your hand should be the owner of this black silk, right?"

"Senior Brother Mingjian"

Lu Shan nodded and said, "Not only is this token belonging to him, but even the information that the ancestor left in the Yin-Yang Taoist Sect, including the identification method, was passed to our lineage by that ancestor before his death."

"Where is that token now?"

Since there is an identification method, Zou Yi naturally doesn't want to delay the time anymore.

"This token is related to the letter from the ancestor, so you must not be careless."

Lu Shan said solemnly: "When the matter here is handled, Lu Shan will definitely take his senior brother to identify this silk."

Since the other party said this, Zou Yi couldn't urge him too much. Zou Yanliu Xin's incident was indeed extraordinary. This time and place were not suitable for further discussion. Moreover, Ye Zhenrong's people had already shown signs of awakening. Besides, under his spiritual sense, the Aberlisa in the room upstairs who was backfired by the martial arts had already had an abnormal condition again. If he could not be treated as soon as possible, he would really suffer from sequelae.

"Since that's the case, then Brother Ye will have your help to take care of you."

By this moment, Zou Yi's mind had already been freed from the previous conversation. The most important thing in front of him was Eberisa's injury. After all, this little girl was injured because of him and could not let go. As she spoke, she stood up and walked quickly upstairs. (To be continued.)
