The system has the function of detecting and extracting metabolite veins.

Even if Du Yun can't see it, as long as he approaches the place where the Yuan Stone Mine is suspected of existing, the system can automatically detect the results without him doing anything.

This time was no exception.

Accompanied by everyone, Du Yun had just come to the edge of Hantan, and the information that the system prompted the discovery of the Yuan Stone Mine sounded in his mind.

Moreover, what surprised him was that this time not only a Yuan Stone Mine was discovered, but it was also a medium-grade Yuan Stone Mine!

"Lord, isn't there really a Yuan Stone Mine in this Hantan?" Guo Jia noticed the joy on Du Yun's face, his eyes suddenly lit up, and he asked.

The others also looked at each other.

It's good to find the Yuanshi mine!

As long as there are enough Yuan Stones in the hands of the lord, not to mention that Dian Wei and Huang Zhong have broken through to the Grandmaster Realm, even martial artists like Guo Jia and Wuxin Old Monk who have entered the innate peak realm can strive to break through in a short period of time.

Hearing Guo Jia's words, Du Yun took a deep breath and nodded: "Well, the Yuan Stone Mine should be under this cold pool, and it is also a medium-grade Yuan Stone Ore Vein!" ”

Compared with the previous groping forward, since occupying Nanshan City and starting a commercial self-cultivation, both he and the subordinates who followed him have learned a lot about things outside of cultivation.

A medium-grade Yuan Stone can not only be exchanged for a hundred low-grade Yuan Stones, but the concentration of vitality contained in it is not comparable to that of the lower grade Yuan Stone.

For martial artists, cultivating with the help of middle-grade Yuan Stones is far better and faster than lower-grade Yuan Stones.

If you can get this medium-grade yuan stone vein, it will definitely be able to greatly increase the speed of the strength of your subordinates, and it is also expected to upgrade Nanshan City to a mid-level city!

However, everything will have to wait until it is collected to know how big the vein really is.

Immediately, he immediately ordered: "Although Feng Xian has already determined that there is no danger in this cold pool, when I do it, you still have to be vigilant to prevent accidents!" ”

"Yes, my lord!"

Everyone responded.

After Lu Bu and the others took a few steps back and made a posture of being ready to make a move at any time, Du Yun suddenly no longer hesitated, and said silently in his heart: "System, extract medium-sized yuan stone veins!" ”

"Ding, ready to succeed, drawing!"

Thundered! Thundered! ……

Just like the last time in the valley near the base of Zhujiazhuang, after Du Yun agreed, the originally calm valley suddenly trembled violently.

The steep mountain wall cracked in the tremors, and countless pieces of gravel fell from it into the cold pool.

And the whole cold pool is even more violently tumbling, like boiling water, the pool water that rises from the bottom of the pool rushes out of the water surface to form a column of bubbling cold water.

At the same time, the water level is slowly decreasing.

In the back, Lu Bu, Hua Tuo, and the old monk Wuxin were so shocked that they almost couldn't help but scream.

That's too much movement, isn't it?

However, Guo Jia and Dian Wei had seen Du Yun's experience of extracting the Yuanshi ore vein, and they were not too surprised, but they just looked at the rolling cold pool with their eyes intently.

"Nothing will happen, will it?" The old monk of Wuxin still couldn't help but say.

Guo Jia smiled and said, "This is a normal phenomenon, wait until the lord will ......."

Woohoo!

But before he could finish speaking, the water surface of the cold pool, which was already fluctuating violently, suddenly soared, followed by a roar full of endless anger sounded in the water.

Under the cold fog, a shadow under the water can be faintly seen rising rapidly!

When he heard the roar of anger, not only Du Yun was startled, but the six Guo Jia people standing behind also changed their faces instantly.

There are even mutant beasts in the cold pool!

In particular, Lu Bu, who patted his chest to ensure safety, had an ugly face, and when he felt the aura emanating from the shadow in the cold pool, he rushed over and shouted.

"Lord, retreat! This...... This is the Grandmaster-level Mutant Beast Aura! ”

Without Lu Bu's reminder, Du Yun had already immediately interrupted the extraction process of the system, and urged his own strength to retreat back quickly.

Whoa!

As soon as he withdrew from a distance of more than ten meters, with the splash of water in the cold pool, a tail covered with dark green scales and more than ten meters long rushed out of the water and pumped fiercely towards the shore.

Burst! Burst!

The terrifying power erupted, causing the air around it to burst into flames.

"It's good to come!"

A trace of murderous intent flashed in Lu Bu's eyes, and his feet stepped on the ground and suddenly rose into the air, and the Fang Tian Painting Halberd in his hand condensed the grandmaster-level Yuan Force and smashed into the tail that was pumped over.

Bang!

The moment Fang Tian's halberd and tail collided together, the terrifying power erupted, directly causing bursts of spatial ripples.

The loud popping sound made everyone's ears ring.

But what shocked Lu Bu was that his blow that condensed the power of the Grandmaster only broke through the scales and made a slight scar, and not even blood flowed.

Woohoo!

The tail was injured, and it seemed to anger the demon beasts in the cold pool.

With another angry roar, the tail of more than ten meters long was like a long whip, directly condensing the cold qi around him, and then instantly pumped towards Lu Bu.

Lu Bu waved Fang Tian's halberd to block, but the rich cold made his body stagnate slightly, and the terrifying power on his tail directly whipped him away.

In mid-air, Lu Bu felt a dull pain in his chest, and he took a few deep breaths before suppressing the urge to vomit blood.

It took a few dozen meters of retreat before stopping.

Immediately, he did not rush up again, but flew down to join Huang Zhong and the others, guarding Du Yun's body.

This chain of battles seemed to have been going on for a long time, but it was only a few breaths.

Under the solemn gaze of Du Yun and the seven people, the huge shadow on the violently fluctuating cold pool finally completely surfaced, and the tail more than ten meters long had been withdrawn, replaced by a mutant demon beast that floated on the water like a snake with its body coiled.

It resembles a snake, its head is like a tiger, its head is hornless, its body is covered with dark green scales, and its abdomen has two sharp claws.

This is a Jiao that can only be seen in mythology!

Living in a cold pool, it is a cold Jiao!

Feeling the anger and killing intent revealed in the eyes of this Han Jiao, Du Yun and the Seven were shocked in their hearts, but they didn't expect that the mutant beast in the valley turned out to be a Han Jiao.

The dragon has no horns.

No wonder the old abbot of Wuxin would say that he heard the sound of a dragon.

The body of the Han Jiao in front of him was already six or seven meters long just when it was exposed to the water, and with more than a dozen long tails hidden in the water, it was more than twenty meters long.

Moreover, its strength has reached the peak of the terrifying Grandmaster Realm!

At this moment, even Lu Bu, who was proud in his heart, felt tremendous pressure, he clenched the Fang Tian painting halberd in his hand and said, "Lord, you and the others will withdraw first, and this Jiao Youbu will stop first!" ”

"Lord, my subordinates and Evil Lai stayed together to help Brother Feng Xian deal with this cold Jiao!"

Huang Zhong and Dian Wei are also Taoists.
