In the hall of Jubi Mountain, the eight demon kings sat down in turn, and they all felt extremely shocked and unbelievable when they heard the news brought by Niu Er.

"Is this serious?" The old man Tiemu's eyes narrowed slightly, flashed a strange light, his expression changed, and he looked directly at Niu Erdao: "This matter is not trivial, what evidence can the virtuous nephew have to show that the human race has a major repair?"

Niu Er was silent, and reached out to take out the old man Yuan Ying he met halfway, an old Yuan Infant of about one foot, his eyes were closed, and his face was expressionless, as if he was a clay sculpture.

"Is this the Avatar Cultivator?" The green toad on the side was the most surprised, it was this person who fought with him for hundreds of rounds and almost killed himself, so he was quite impressed.

"Oh?" The old man Tiemu glanced at Niu Er deeply, stretched out his hand to grab it, and the Yuan Ying immediately jumped up from Niu Er's second hand and flew into his hand.

His eyes narrowed slightly, and his thoughts probed into the Yuan Infant, and after a while, the old man opened his eyes, sighed, and said, "Sure enough." ”

The palm of his hand was slightly raised, and the yuan baby flew back to the cow on its own.

Looking around at the surrounding demon kings, the old man of Tiemu said in a deep voice: "What Niu Xian's nephew said is good, but there are Mahayana masters coming to the human race, and there are also two merger masters, and there are as many as sixteen people in the god transformation stage. ”

"What?" The demon kings were shocked for a moment, they didn't expect the human race to gather so many masters, was it just to occupy the two high mountains, or were they preparing to attack the many demon clans in the endless mountain range?

"The younger generation has one more thing to report to the demon kings. Niu Er suddenly spoke, his voice was loud and his eyes were calm.

"What's the matter?" said with a smile, "The previous news has a great contribution to you, and what other important things are to be said." ”

"Hehe, the juniors are in the place where the human race gathers, and I have a piece of news. Niu Er smiled slightly, and his honest face showed a little cunning.

"What kind of news? If it's important, you might as well take another credit. Xiong Batian said with great interest, and his eyes swept over everyone slightly.

"The juniors have received news that the Terrans have found a vein of copper ore in the place where they are stationed. ”

"What?" At this time, the group of demon kings suddenly stood up, even more shocked than the previous news.

"Niu Er, this is not a joke, what evidence do you have that the human race has discovered the mineral vein, you know, my demon clan has occupied this place for thousands of years, but no one has ever found it. ”

The green toad was the most suspicious, those areas belonged to the jurisdiction of Jubi Mountain, but under his nose, hundreds of thousands of years of cultivation had not been able to find half of the mineral source, and the human race had only been here for more than a year, and he had discovered a copper mine. Although it is not a particularly precious ore, it is many times more advanced than the commonly used dark iron.

Niu Er took out a dilapidated storage bag, raised his hand and threw it, a half-foot-sized stone smashed on the ground, the bones tumbled and tumbled, and there were red spots on it, flickering, eye-catching.

"Cuprite!" The green toad's eyes were about to pop out, but he didn't expect it to be true, which made him Yan Zòng feel a blow, sitting on the stone chair with his buttocks, his cheeks bulging, and his big face was red, almost dripping blood.

Old Man Tiemu nodded and said, "I'm afraid, that's why that Terran overhaul came." ”

His eyes swept over all the demons present, all of them were in their hearts, and the green toad also quickly sat down, listening to the old man Tiemu continue: "The human race must be watching the various mineral sources of my endless mountain range, so if you want to use Jubi Mountain as a fulcrum to gradually encroach on the surrounding mountains, I am afraid that you want to kill my demon clan." ”

Seeing that everyone was looking at him, the old man Tiemu said slowly: "For today's plan, you urgently notify the surrounding demon kings to come to support, and we will jointly summon the demon generals to come down and resist the overhaul of the human race." ”

In the next few days, dozens of Yuanying demons who were good at wind escape techniques flew out of Jubi Mountain one after another, rushing to all directions.

In the Wushan Mangniu Cave, Niu Er looked at the fat mouse like a suckling pig in front of him, cultivated as in the early stage of Jindan, the golden fur was as bright and silky as brocade, tightly wound by the spider's condensed cobweb, hanging high on the top of the cave, the two thieves' eyes were rolling around, and when they saw the honest young man in front of the spider, they immediately screamed, and their voices were high-pitched, immature like a baby.

"Hey, the young master is here, the mouse will greet you. Hurry up, let Sister Spider put me down. ”

The two thieves' bright little eyes were teardrops, and they looked pitiful, and their voices were choked and pleading.

"Oh, do you know me?" Niu Er raised his eyebrows, his big dark eyes squinted at the rat demon, and there was a slight smile on his face.

"That's it. "The fat pig-like mouse, struggling with four calves in the net, changed his position, and could see the traces on the skin, deep into the meat, but the words on his mouth were like the Yangtze River, gushing endlessly.

"The young master is wise and martial, the jade tree is in the wind, **chic, and the wisdom is outstanding,...... In this Wushan area, no one knows, no one knows, and it is the idol that the little demon worships every day, and the gods who worship day and night......"

About half an hour later, the rat demon said that his mouth was full of white foam, raised his bright red little tender front paws, stretched out his hand to wipe it, and continued to praise, but was interrupted by Niu Er in a hurry, looking at it, he said that he had been talking about a day and a night, and I am afraid he couldn't finish it.

"Okay, I'll just ask you, the first few times you ran into my cave and stole the elixir?"

"This ......", the rat demon glanced at Niu Er cautiously, and saw that he didn't seem to be angry, so he hurriedly nodded, and said with a grin: "That, the little demon has admired the young master for a long time, so he secretly listened to the location of the young master's cave mansion, and wanted to take a look at it secretly, who would have thought that when he left, he accidentally took away a few spiritual grasses, damn the small one, and ask the young master for forgiveness." ”

The more he talked, the more aggrieved he became, and a few tears fell out of his eyes, his face was full of grievances, and his small eyes secretly glanced at him from time to time, and the strange light flickered, and Niu Er felt very funny, but he knew the cunning of this rat demon in his heart.

In the first two retreats, each time the spirit grass pill was placed on the ground, and at the end of the retreat, it would be found that there was a spirit grass that had disappeared inexplicably, and it was a rare spirit grass that was more than hundreds of years old.

Therefore, before going down the mountain, Niu Er deliberately put more than ten five-hundred-year-old spirit grass in the cave, and secretly instructed the spider to guard the cave carefully, and pay attention to the monsters who can do the art of earth to steal it.

I didn't expect this to come back, and it really surprised him. You must know that there are thousands of demon clans, but there are few masters who can easily pass through the underground, especially in the edge of the Endless Mountain Range, there are even fewer left.

If he could subdue this fat mouse, it might bring unexpected receiving, Niu Er was full of joy, and told the spider to watch carefully, and turned away, ignoring the ghost crying wolf howl of the big mouse.

All the way to the peak of Wushan Mountain, Niu Er threw out four white flags and shot them to the four corners, and as soon as he landed on the ground, a mist was generated out of thin air, enveloping the top of the mountain layer by layer. Then the storage bags are placed in turn to sort out the receipt of this downhill.

Although the cultivation of those two prospectors is not high, there are not many spirit stones in their pockets, and there are nearly 5,000 pieces, which are specially rewarded by Taiyi Sect for the discovery of red copper. There were some other remaining exercises, only the ore hunting technique made him pay a little attention to it, and put it in his arms.

Then there was the storage bag of the god transformation monk, to Niu Er's surprise, there were less than a thousand spirit stones in it, but there were nearly a hundred bottles of various pills, most of which were pills used to assist cultivation during the god transformation period, but there were few left to treat internal injuries, and they were all eaten by him.

More than a dozen jade slips, the most surprising to Niu Er, in addition to the alchemy technique, there are actually several rare and precious secret techniques, such as the incomplete Five Elements Escape Ancient Technique, although only the Earth Escape Technique is relatively complete, but it is also rare in the world, if it is spread, it will definitely cause a war.

In ancient times, cultivation became a trend in the world, there were countless masters, immortals were everywhere, and all kinds of powerful exercises and secrets were not comparable to now.

Therefore, everything with the word "ancient" makes people rush to it, and they do not hesitate to give up their lives.

In addition, it is also recorded that there is a blood shield technique used to escape at critical moments, sacrificing part of the true blood in the body, so that the speed of flying away is increased by more than ten times, reaching an extreme, so that the enemy cannot catch up.

One by one, he picked up and watched, and each jade slip brought him a little surprise, and carefully put it in his storage bag until the last two jade slips.

The crystal jade slip is different from the previous white color, with a faint golden glow on it, and a small gossip pattern is engraved on the lower right corner of the jade slip.

Niu Er stretched out his divine thoughts and probed in, but was blocked by a layer of golden mangs rising from the jade slip, and he was not allowed to enter at all.

Niu Er was surprised, you must know that the cultivation of the Soul Falling Technique is quite accomplished, and the current Divine Thoughts are not much different from Huo Wuyi and the others in the middle stage of the Yuan Infant, and they are even a little stronger, and they are actually blocked out by a thin layer of prohibition.

Taking out the old man's Yuan Baby, Niu Er performed the soul searching technique, and his brows furrowed slightly after half a ring, he didn't expect that the origin of these two jade slips was so amazing.

There are large plains in the north of the Endless Mountain Range, and there have been many immortal cultivators since ancient times, and there are countless buried predecessors in the Cave Mansion. Many of them are the legendary Gu Immortal Cave Mansion, and every time they appear, they make people all over the world crazy, setting off countless bloody storms.

In the south of the plains, the two sects of Taiyi and Ziyang are respected, and in the north, the Feiyun Sect is the dominant family, ruling over a territory of 100,000 li and countless mortal kingdoms.

About one hundred and fifty years ago, an Ancient Cave Mansion was born in the area near the south of the Feiyun Sect, and at that time, the three major sects all wanted to monopolize it, causing the joint resistance of many small and medium-sized sects and many scattered cultivators, and finally they had to share their quotas and explore together.

At that time, Yue Shan, who was still in the middle of the Yuan Infant Period, was lucky to get a place with a heaven and earth spiritual fire and a superb alchemy technique, and he gained a lot in that cave mansion, a copper furnace for alchemy, a golden jade slip next to it, and some rare elixirs.

What Niu Er didn't expect was that Yue Shan hadn't been able to probe his divine thoughts into it at that time, and he didn't barely break through a gap until he advanced to the gods. As far as he knew, there were nine layers of prohibitions sealed in the jade slip, and each layer required a powerful divine power to break through.

And Yue Shan tightly broke a prohibition, and the content inside surprised him, what was recorded in it were some ancient pills that had long been extinct and legendary, the most famous of which was the Avoiding Tribulation Pill, which could allow people to avoid the Heavenly Tribulation and directly advance the anti-heaven pill.

This is only the low-level pill recorded in the first layer, and behind it may only be an unimaginable elixir, and even the legendary elixir that can make mortals directly soar into immortals.
