"This is the Tyrant Spear, crafted by a Spirit King expert from fine steel and cold stone. Try channeling your true qi into it," Yun XiaoTian said with a slight smile.

Upon hearing this, Li Lin slowly channeled a strand of true qi into the Tyrant Spear.

"Boom!"

Suddenly, the Tyrant Spear heavily fell to the ground, causing a slight tremble. Li Lin's complexion changed dramatically as well. Just by slightly channeling true qi, the Tyrant Spear suddenly became as heavy as over a thousand kilograms, immediately dropping from his hand.

"Hehe, once true qi is channeled into this Tyrant Spear, its weight can freely change, possessing strange and unpredictable abilities. In our Yunyang Sect, there are very few disciples who use spears. I originally planned to give it to Li Dajiang, the Life-Taking Spear, but you've rendered him crippled," Yun XiaoTian sighed slightly.

"What a great spear." Li Lin became even more astonished by the Tyrant Spear at this moment. A weapon crafted by a Spirit King expert from fine steel and cold stone is truly remarkable.

Following that, Li Lin saw many more exceptionally good weapons. If these were put outside, they could cause a frenzy, but here in the Yunyang Sect, they could only be stored in the Thousand Treasure Vault.

Inside the cave, every treasure made Li Lin somewhat amazed. They were definitely at the level of true treasures. Looking at the rows of jade cabinets filled with medicinal herbs, crafting materials, and weapons, Li Lin was continuously astounded. This is the gap. Compared to the Yunyang Sect, even the collection of the Flying Spirit Gate is lacking.

"Li Lin, you should quickly choose three treasures. As for whether there's ten-thousand-year-old Red Copper among them, it's up to you," Yun XiaoTian said with a slight smile upon seeing Li Lin's gleaming eyes.

"Sect Leader, let me look a bit more," Li Lin said lightly. He only had three chances, and he must choose wisely.

"Take your time, I'm in no rush," Yun XiaoTian said lightly.

"What is this?" On the fourth jade cabinet, Li Lin saw a set of white, thin armor, resembling underwear, made of a seemingly very special material, thin as a cicada's wing.

"This is a set of protective armor, which requires fire attribute to activate. I originally wanted to give it to Hong Ling, but unfortunately, Hong Ling is a martial artist of water, wood, and wind attributes. This protective armor can withstand a full-force attack from an opponent of the same cultivation level without any harm, which is quite remarkable. You can take it, as it will be beneficial for your defense," Yun XiaoTian said.

"Such a remarkable treasure." Li Lin was somewhat tempted. His own Qing Ling armor, combined with this armor, would definitely make his defense stronger. However, not knowing whether this defensive armor would still be effective under the Qing Ling armor, and considering that his defense was already quite good, he hesitated for a moment and then put down the protective armor.

Yun XiaoTian was somewhat surprised. This protective armor was definitely a good treasure, a life-saving treasure that is generally highly valued by everyone. Unexpectedly, Li Lin was not moved.

Looking around the cave, if it were just a single treasure, Li Lin would definitely be very tempted. However, with tens of thousands of treasures together, Li Lin, after being tempted, could only end up dazzled, not knowing how to choose.

Li Lin even started to feel a bit dizzy from looking. Accidentally, his gaze landed on a brocade box on the sixth row of jade cabinets, about twenty centimeters long and ten centimeters high.

This brocade box was inconspicuous in the cave, but Li Lin knew that anything stored here must be extraordinary. He then opened the brocade box.

Inside the brocade box, there were two palm-sized yellow jade slips, emanating a faint earth attribute aura. The more Li Lin stared at these two jade slips, the more he felt their unusualness. It seemed as if there were waves of violent energy contained within, making his heart palpitate the more he looked.

"This is no ordinary item. It's said that this was created by a Martial King peak expert and a Spirit King peak expert after years of research. It's called Earth Sha Xuan Lei. Inside the jade slips, there's an attack power equivalent to a Martial Venerable. By channeling true qi, you can throw the Earth Sha Xuan Lei to activate its attack. Although its power cannot compare to a Martial Venerable, its force is enough to kill a six-layer Martial Commander and severely injure a seven-layer Martial Commander. Originally, there were five pieces of Earth Sha Xuan Lei. When our Yunyang Sect obtained them, there were only four left. Hong Ling has always had two pieces, leaving these last two," Yun XiaoTian said.

This tale has been pilfered from Royal Road. If found on Amazon, kindly file a report.

"To have such a thing, with sealed attack power inside the jade slips, activated by channeling true qi, is terrifying. Created by a Spirit King and Martial King peak expert, able to kill a six-layer Martial Commander, severely injure a seven-layer Martial Commander, such treasures are monstrous," Li Lin thought to himself.

"Sect Leader, these two pieces of Earth Sha Xuan Lei count as one treasure, right? I'll take this," Li Lin grinned, without any hesitation, directly putting the brocade box into his spatial bag hanging at his waist.

"You're taking this? Although these two pieces of Earth Sha Xuan Lei are somewhat special and definitely extraordinary, they can only be used once and then are gone. There are still many treasures here, stronger than these two pieces of Earth Sha Xuan Lei. You can choose again," Yun XiaoTian said puzzledly to Li Lin, specifically reminding him that the Earth Sha Xuan Lei can only be used once. Although extremely extraordinary, it's ultimately a one-time-use item. There are many treasures in this Thousand Treasure Vault more precious than the Earth Sha Xuan Lei.

"I'll take this," Li Lin said, clearly seeing that the Earth Sha Xuan Lei, although extraordinary, wasn't too conspicuous among these treasures.

But Li Lin had his own plans. In Li Lin's heart, what's most important is to save one's life. These two pieces of Earth Sha Xuan Lei are definitely good items for saving oneself now. Throwing one can directly kill a six-layer Martial Commander, severely injure a seven-layer Martial Commander. Such good items are undoubtedly the most suitable for him.

Seeing Li Lin's insistence, Yun XiaoTian had no choice. Having these two pieces of Earth Sha Xuan Lei at hand, at least there's a life-saving means in times of crisis. Perhaps this youngster saw this point.

Continuing to search for the second treasure, Li Lin was in a dilemma, not knowing what to choose. The whereabouts of the ten-thousand-year-old Red Copper were still unknown.

"Where exactly is the ten-thousand-year-old Red Copper?" Li Lin searched everywhere, his main goal being to find the ten-thousand-year-old Red Copper.

Although the cave was not small, searching for items was not easy. With his mind probing around, Li Lin mainly focused his search on crafting materials.

Ten-thousand-year-old Red Copper is also a crafting material. Using the process of elimination, Li Lin immediately ruled out all the crafting materials he recognized.

There were not a few crafting materials in this Thousand Treasure Vault. After eliminating the majority, Li Lin still had about twenty to thirty types of crafting materials he didn't recognize.

Thinking about the introductions to crafting materials in the Heavenly Spirit Record, Li Lin immediately began to identify and eliminate them one by one.

Watching Li Lin's actions, Yun XiaoTian was becoming more and more amazed. Li Lin seemed to recognize all these crafting materials.

After Li Lin eliminated one crafting material after another, in front of him, there were still three crafting materials left.

One was a thick-as-an-arm, two-meter-long yellow fine iron, extremely hard.

One was a two-meter-long cylindrical object resembling gold, surrounded by a faint flowing light.

The last one was a half-meter-tall, one-meter-wide yellow irregular square object, looking inconspicuous.

When Li Lin moved these three materials together for comparison, he found that all three crafting materials were extremely heavy. Among them, the last black crafting material was the heaviest, requiring him to exert double the true qi just to move it, weighing at least five to six hundred pounds.

Watching Li Lin moving these three crafting materials, Yun XiaoTian's expression changed imperceptibly, but the corner of his eyes involuntarily twitched, seemingly due to surprise.

Li Lin, always observing Yun XiaoTian's gaze, saw the change in his eyes at that moment, almost confirming that the ten-thousand-year-old Red Copper was among these three crafting materials. After repeatedly examining the other materials, he was basically able to determine they were not ten-thousand-year-old Red Copper.

Somewhat relieved to have narrowed down the ten-thousand-year-old Red Copper to these three materials, Li Lin also relaxed a bit, making it easier to find.

His gaze then fell on these three crafting materials, probing with his breath, but he couldn't discover anything. These crafting materials, not having been refined, didn't have much energy fluctuation, unlike medicinal herbs, where higher-grade ones have greater energy fluctuations.

Therefore, just by probing with his breath, Li Lin couldn't determine which of the three crafting materials was the ten-thousand-year-old Red Copper.

However, after a moment, Li Lin's mouth showed a slight smile, and without further thought, he directly put the third yellow crafting material into his spatial bag, saying, "Sect Leader, I'll take this."

"Li Lin, how did you know this is ten-thousand-year-old Red Copper?" Yun XiaoTian was immediately astounded, his eyes wide open. He had not expected Li Lin to actually recognize the ten-thousand-year-old Red Copper.

"Quite simple," Li Lin smiled slightly. "As far as I know, ten-thousand-year-old Red Copper seems to have been researched by many experts in the sect and must have been attempted to be refined, so there would be traces on it. The other two crafting materials were shining brightly, without any traces, so I determined that what I just picked up is ten-thousand-year-old Red Copper."
