Han Li's figure suddenly stopped, his eyes flashed and looked at the surrounding stone walls.

Seeing this, Nanlong Hou smiled silently and said, "Fellow Daoist Lu is worthy of being a master of weapon refining, but he has discovered it at just a glance."

Lu Weiying looked at Han Li with some confusion and asked, "Fellow Daoist, what have you discovered?"

Han Li faced the wall and pondered without saying a word. However, Nanlonghou behind him explained: "Didn't you always be curious? Why did I have to enter the inner valley through this passage full of Arctic Yuanlight instead of looking for another entrance? This is the answer."

As the Marquis of Nanlong said, he threw out a golden flying knife from his sleeve and stabbed it on the stone wall.

A 'clang' sound!

The magic weapon, the mid-stage Nascent Soul cultivator, released by Nanlonghou, slashed onto the stone wall, and made a crisp sound like metal collision, and bounced straight away.

The three of them were shocked and subconsciously looked at it. They saw that the flying knife of Nanlonghou could only leave a trace several inches deep on the stone wall, and there were faint silver lights in the knife marks.

"This is..." Lu Weiying's face flashed with surprise, and he hurriedly stepped forward a few steps, walked to the point where the knife marks were cut, and observed carefully.

"Gangyinsha, there is actually Gangyinsha raw ore in this stone wall?" He only observed for a short while before his voice trembled slightly.

As soon as they heard the three words Gang Yinsha, the three of them suddenly changed their expressions. And inside Han Li's body, a burst of laughter came into his spiritual consciousness.

"It's really Gangyin Sand! I said I was right. So many Gangyin Sands are enough for Lu Yunze tossing."

Han Li showed a deep thought on his face. He had naturally heard of the material Gangyinsha. This is one of several materials that can be added to refining weapons and make the magic weapon stronger. In terms of effect, it is a rare material second only to refining crystals.

This material itself is extremely hard and difficult to urge magic weapons. Whether it is the Chaos Star Sea or the Immortal Cultivation World in the South, it is a nearly extinct existence.

Unexpectedly, there is actually a Gangyinsha ore in this Demon-Desert Valley!

When Han Li was ecstatic, the three Nanlong Hou looked at each other and saw the fiery look in each other's eyes.

But after a moment, Nanlong Hou took a deep breath, turned his head and walked into the passage.

"Let's go. Let's go to the inner valley to explore treasures first." The Marquis of Nanlong said without looking back.

"Let's go now? These Gang Silver Sands are rare treasures. We might as well knock some first." Lu Weiying hesitated for a moment and said with reluctance. But beside him, Pei Zhengxiong pondered for a moment, sighed, and followed the Nanlong Hou.

"Brother Lu, give up. Have you seen how hard these Gangyin sand are? Haven't you seen them personally just now? Although there may be Gangyin sand ore in the entire ore here, a piece of raw ore the size of a fist can only extract a tiny bit of Gangyin sand the size of a rice grain. How long does it take and how much mana you consume to cut off enough raw ore? Besides, although this thing is precious, don't forget that what we lack now is not these external things, but spiritual medicines that can prolong life and quickly improve our realm. Otherwise, in the end, we will only be a pile of white bones." Nanlong Hou frowned, looked at the old man, and said with great meaning.

When Lu Weiying heard Nanlong Hou say this, he was stunned at first, and then nodded suddenly.

"Brother Nanlong said very well! I was so confused by the treasure that I almost forgot the main purpose of this trip. Thank you, Brother Nanlong, for reminding me." The old man was not an ordinary monk. After being reminded by the Marquis of Nanlong, he immediately woke up and clasped his hands and fists at Marquis of Nanlong with a hint of gratitude.

Then he stopped looking at the stone wall, for fear of being tempted again and walked into the cave soon.

Han Li was still walking in front and said to the voice inside his body: "How long does it take for Lu Yunze to complete the mining of this raw ore?"

"According to current productivity, it will take about five years." Han Li said with a smile on his voice inside.

"If he can stop the project at hand and draw out the resources inside, the time can be shortened to a year."

"Project?" Han Li frowned. He had heard that Lu Yunze had secretly mobilized most of the resources and subordinates in his hands to the same project, which directly led to his lack of defense. Most of his subordinates had disappeared since the war with the Demonic Dao.

If it weren't for his previous battle that shocked the entire Tiannan, someone would have been unable to hold back and prepared to attack Lu Yunze's territory.

"What kind of project is it? What investment is this?" Han Li asked curiously.

"He won't let this talk. The only thing we can tell you is..."

"That's the ultimate dream of a man!"

Han Li twitched the corners of his mouth and penetrated into the passage helplessly.

The four of them walked for a while, but they suddenly realized the passage and the passage became more wider.

In this wide channel, strange stones like stalactites are spread from top to bottom, and slits of silver-white light are emitted, illuminating the entire channel to the extreme.

These silver threads are strange and abnormal. Although they are obviously invisible objects, each light thread is extremely clear and as if it is tangible.

"Arctic Yuanguang!" Han Li's heart trembled.

This is the biggest reason why Lu Yunze agreed to the proposal of Nanlonghou. Among the target priorities listed by Lu Yunze, this kind of spiritual importance that seems to be substantial is even above the channel itself.

Han Li couldn't understand what he planned to do with this Arctic Yuanguang, and he didn't bother with his inexplicable thoughts.

For him, this was just a hindrance.

Han Li raised his hand and a black ring flew out, and then circled and fell into the palm of his hand. The ring was filled with inspiration!

As soon as he opened his mouth, a ball of green essence spurted out from his mouth and covered his finger ring.

The black light flashed, and all the green air was absorbed by the rings. Then, with a whoosh, it flew to the top of Han Li's head and couldn't move.

Han Li raised his hand expressionlessly and hit him with a magic trick.

The Liangyi ring trembled slightly, then shrank and rose. In a blink of an eye, the ring turned into a giant ring with a diameter of five or six meters.

"Go!" Han Li rushed to the ring and exhaled gently.

The ring made a strange low sound and shot out instantly.

Everyone's eyes suddenly became solemn.

I saw the giant ring rushing into countless thousands of light threads, and an incredible scene appeared.

The straight light threads were like the messed-up water surface, and the moment the giant ring entered, it became chaotic. As the black light flashed, all the silver threads immediately turned miraculously, avoiding the finger circle and walking around the way. It was like a spiritual communication!

The few people breathed a sigh of relief and quickly entered the protection range of the Liangyi Ring and slowly flew into the passage.

Entering this narrow passage, silver-white light threads float gently around everyone like branches hanging from trees in the dense forest. Although they seemed weak, the four of them did not dare to be careless at all.

The power of this Arctic Yuanguang is definitely not something that the Nascent Soul monk can withstand! At least a Nascent Soul monk like them cannot do it.

The four of them passed through this passage vigilantly, and with the Arctic Yuanlight disappearing bit by bit, the four of them finally arrived at the end of the passage.

Passing through a narrow cave entrance, a huge mountain range covered with countless mountains and rivers appeared in front of the four people, and they looked almost boundless. But at the same time, it was a colorful world. Whether in the sky or on the ground, there were faint glows floating everywhere.

These rays of rays are of different colors and vary in size. The large ones are as large as several miles, just like the sunset in the sky, and the small ones are only a few feet long, like thin veils, all of which are extremely gorgeous.

"Be careful, this is a scene of the chaotic spiritual energy of heaven and earth here and the complex prohibitions. These ancient monks are really powerful, and they can completely destroy the fundamentals of the spiritual energy of heaven and earth here. In this way, no matter whoever casts spells here, we may be affected somehow."
