This is a hidden vein, and if it weren't for Chen Tian's ability to see, he wouldn't have been able to discover this vein hidden in the mountain.

Why there is a hidden vein here, why these miners are still mining, when Chen Tiansheng's eyes fell on the red ore on the minecart, all questions were solved.

Chen Tiansheng's breathing became a little rapid, on the one hand, due to the power of his eyes to the limit, and on the other hand, because of the red ore on the minecart.

This red ore is hematite!

Hematite, along with black iron, green iron, dark iron, and cold iron, is an extremely valuable material for refining weapons.

These materials have extraordinary properties and are used to refine high-grade weapons. Top-grade weapons, take Qingyang Houfu as an example, the four major capitals of a country will not have more than the number of high-grade weapons in both hands, one is because the refining of high-grade weapons is difficult, non-refining masters cannot refine them, and the second is the rarity of this material.

If only some of these materials are mixed into ordinary weapons, the grade of the refining will be greatly improved.

Song Koi's koi sword is made of green iron, and it is a rare divine weapon.

The bladeless sword in Chen Tiansheng's storage bag was made of black iron, but it appeared in the refining process, resulting in the failure of refining and the destruction of the sword.

It has become the appearance of today's uneven, broken copper and iron.

What Chen Tiansheng didn't expect was that there was a hematite hidden in this small two-star vein Yan iron mine, and the output of hematite was quite considerable.

According to the classification of iron ore in the Tang Kingdom, this Yan iron ore is at least a five-star vein, which is a super vein guarded by the pro-army of the capital or the imperial capital, and even needs to be personally controlled by the innate powerhouse.

And before this, the mayor of Yantie Town didn't know about it, and actually wanted to take this hematite for himself.

The line of sight changes in the hematite movement, the mine is quite rudimentary, and the scale is a little small, obviously this hematite has only been discovered for a short time.

As the mine cave extends outward, the hematite mine is connected to the Yaniron mine cave, but this mine is blocked in a very hidden way, so it is difficult to find the hematite hole in the mountain here.

Chen Tiansheng was shocked in his heart, and at the same time, he was even more puzzled in his heart, the development of this matter had exceeded his guess.

Chen Tiansheng pinched his palm, and a small rub of iron powder slipped from his palm. This was the first time he had entered the mine and found that Iron Essence was an iron essence one grade higher than ordinary iron.

He originally thought that this vein could produce refined iron at most, which was a three-star vein, but now this matter is no longer something he can solve, so he must hurry back to the imperial city and report to his master, Chen Tiansheng secretly thought in his heart.

Chen Tiansheng retracted his gaze, and there were several explosions outside the vein.

His body shook, and he ran towards the outside of the mine at great speed, taking advantage of the fact that the attention of the guards in the mine was attracted by Song Wushuang's movements, Chen Tiansheng took the opportunity to sneak out of the mine.

The figure turned into a dark night, and ran down the mountain at great speed in the snowy night.

As they reached the foot of the mountain, more than fifty soldiers were surrounding a masked man in the snowfield. Chen Tiansheng recognized the masked man as Song Wushuang at first sight, found a place to change his clothes and cloak, and lowered the brim of the cloak.

Stretched out his hand and put it in his mouth and whistled, the good horse heard Chen Tiansheng's whistle, snorted, and turned into a wind and ran towards Chen Tiansheng, followed by a thief's horse.

When the good horse ran in front of him, Chen Tiansheng turned over and led another horse to break into the guard's encirclement from the periphery.

One man broke through on a single horse, and for a moment these guards were caught off guard.

"Get on the horse!" The brim of the hat covered most of Chen Tiansheng's face, but Chen Tiansheng's eyes were of special strength, and lowering the brim of the hat would not affect his vision.

When the masked Song Wushuang heard this, he immediately came to his senses and turned over on his horse.

The two broke through on horseback, twenty or thirty guards holding spears in front of the two, the reins in Chen Tiansheng's hand were raised, and a single palm was slapped, and in an instant, more than a dozen palm prints the size of shields appeared, and they bombarded towards the group of guards in front of them.

The palm print was amazingly powerful, and with one palm, the twenty or thirty guards who stood in the way were knocked down, and the two of them jumped out of the encirclement with one leap.

Seeing that the two of them had escaped from the encirclement, the guards behind immediately took their bows and arrows, and in an instant, dozens of cold stars rained towards the backs of the two, and Chen Tiansheng turned around and slapped his palm.

The palm power is like a copper wall and iron wall, blocking all the dozens of arrows.

When those guards were about to release the second arrow, Chen Tiansheng and Song Wushuang had already ridden out of the range of the bow and arrow and disappeared in front of the eyes of all the guards.

"Brother Tiansheng, what should we do now?" Song Wushuang asked breathlessly while riding his horse.

Chen Tiansheng frowned and pondered, and said: "Wait a while, we will separate, you take a detour to the foot of the Yan Iron Mine, Sun Pengtian is healing in the cave, you go to Heifeng Mountain with him, I will go to the town to pick up Shangguan Yuhan, and then catch up with you and go to Heifeng Mountain to save people." ”

After that, Chen Tiansheng clamped his legs, and the horse under his crotch ran away in pain.

The two parted ways, and when they were outside the town, Chen Tiansheng turned over from his horse and landed, and returned to the courtyard where Shangguan Yuhan lived in a few leaps.

Chen Tiansheng knocked on Shangguan Yuhan's door in three steps and two steps, Shangguan Yuhan opened the door and saw that it was Chen Tiansheng and said, "What's the matter?" ”

"Don't ask so much, now Meng Lingfeng and Qin Lexiang have an accident and have been ambushed by the thieves of Heifeng Village, let's hurry up to Heifeng Mountain to save people." Chen Tiansheng said hurriedly.

"Up to Black Wind Mountain, just the two of us?" Shangguan Yuhan looked puzzled.

Chen Tiansheng picked up Shangguan Yuhan and walked out, saying as he walked: "Sun Pengtian and Song Wushuang are waiting for us on the road, we have to hurry up, so that we can't catch up with the two of them." ”

Shangguan Yuhan's face was surprised, and he said in surprise: "Didn't the two of them go to Tiger Prison City to mobilize the government army, why did they appear here again?" ”

Chen Tiansheng jumped to the stable, took out the remaining horses, turned over and stepped on one of them and said, "They have also been ambushed by the thieves of the Black Wind Mountain, but I have already rescued them, now go to the Black Wind Mountain and rescue Meng Lingfeng and Qin Lexiang." ”

Hearing Chen Tiansheng's explanation, Shangguan Yuhan also turned over and got on the horse, and the two galloped all the way, and after running for dozens of miles, they caught up with Song Wushuang and Sun Pengtian in front.

After some pranayama, Sun Pengtian's face at this moment improved significantly.

Four people and four horses, galloping all the way, in less than a quarter of an hour, they have reached the foot of the Black Wind Mountain. The four of them turned over and dismounted, and in front of them was a forest and snow field, which was impassable for horses at all, and there was no road in front of them.

Sun Pengtian and Shangguan Yuhan's faces both showed embarrassment, the Black Mountain Range is entrenched for hundreds of miles, and this group of thieves on the Black Wind Mountain is also the largest group of thieves within a radius of thousands of miles, if you want to find the Black Wind Village in this Black Wind Mountain within a radius of a hundred miles, it is not an easy task.

"Wushuang, it's up to you." Chen Tiansheng said in a deep voice.

"Yes, Brother Tiansheng."

Saying that, Song Wushuang took out the rune bird from his sleeve, raised his hand into the air, and the rune bird rose into the air, turning into a speedy flight towards the forest sea snow field.

"What is this?"

Sun Pengtian and Shangguan Yuhan both showed a look of surprise on their faces, which made Song Wushuang very useful, and one of them rushed into the Lin Hai Snow Plain first.
