Xin Yan manipulated the machine man, galloping across the martial arts arena in the back mountain, rushing left and right, practicing all kinds of combat skills, and Nangong Yunshan and the maids were all envious.

I saw Xin Yan's machine man turn into a human form for a while, holding a shield in one hand and a sky-shattering crossbow in the other, charging and firing crossbow arrows at the same time. I saw a burst of red light flashing from the Heaven-shattering Divine Crossbow in the hand of the machine man, and the three [Flame Armor-Piercing Arrows] turned into three streamers and attacked the target.

"Boom, boom, boom!"

Almost instantly, several mountain-like boulders standing on the martial arts arena were hit by the [Flame Armor-Piercing Arrow], and they exploded violently, turning into three flames.

"Whoa, that's powerful. ”

"If you are hit, I'm afraid that even the master of condensation will inevitably be injured!"

......

For a while, all the maids were talking. Nangong Yunshan reminded the maids: "The [Flame Armor-Piercing Arrow] is made of the bones of the four-grade rotten bone demon beast, and it is engraved with two rune arrays of armor-breaking and flame, which can easily break through the four-grade battle shield and strong armor, and the flames on the arrow are even more terrifying, and when it encounters any item or flesh with spiritual power, it will burn violently until the spiritual power is exhausted. If you encounter this kind of flame in the future, you must not force it or block it with a magic weapon, otherwise you will suffer a great loss. ”

"Bah, this flame doesn't look good. Why is it so powerful?"

A maid standing next to Nangong Yunshan asked. This maid's name is Yue'er, she has followed Nangong Yunshan since she was a child, and she is Nangong Yunshan's personal maid, and she is the closest to Nangong.

Nangong Yunshan said with a straight face: "Don't underestimate this flame. This is the heavenly fire, as long as anything with spiritual power is stained with a little bit, it will burn violently, as long as the spiritual power is endless, the flame will not be extinguished!"

Yue'er and the maids were all taken aback, and they couldn't help but think about the terrible consequences of using magic weapons to block if the enemy was unclear.

It turned out that in order to increase the power of the [Flame Armor-Piercing Arrow], Xin Yan created an original spirit sealing rune array, which could seal a wisp of heavenly fire in the rune arrow. When the Flame Piercing Arrow hits the target, the sealed Heavenly Fire will be released, devouring everything with spiritual power.

"Opportunistic shortcuts, it's hard to get into the hall of elegance!"

The Red Demon was dismissive of this. But he also had to admit that Xin Yan was clever.

The Heavenly Fire condensed by "Heavenly Fire Refining God" is one of the purest flames in the world, and its power is extremely terrifying. However, with Xin Yan's current cultivation, he is still shallow, and he can't use it as he wants, and he can barely deal with stationary targets, but it is difficult to hit targets that move extremely fast.

Xin Yan found another way, sealing the heavenly fire in the rune arrow, which can be fired at any time, no matter how fast the enemy moves, it will not escape the tracking of the [Flame Armor Piercing Arrow].

The [Flame Armor Piercing Arrow] was extremely powerful, and Xin Yan was very satisfied with it. The only problem is that Flame Piercing Arrows are extremely difficult to refine, and the success rate is extremely low, often only one or two out of ten arrows will succeed.

And the bones of the four-grade rotten bone demon beasts that refine the Flame Armor Piercing Arrow are extremely rare and rare, and each one is worth a lot of money, even if it is as rich as Xin Yan, it feels a little unbearable.

"Why don't you? Let's try a few more. ”

"That's right. Let's have another game and let's see. ”

......

The maids stopped when they saw that Xin Yan had only shot three shots, and they all began to coax.

"Don't play, don't play!" Xin Yan's head shook like a wave drum. After shooting those three [Flame Armor-Piercing Arrows] just now, he was so heartbroken that he was dying, let alone shoot a few more.

"Don't be so stingy, isn't it just a few arrows?"

"Yes, yes, or you shoot at us this time and see if we can catch it." ”

Where are the maids willing to follow, they are entangled in Xin Yan, and they have to let him shoot a few more.

"Don't play, really don't play!"

When Xin Yan heard this, his face immediately turned pale with fright. For him, wasting the [Flame Armor Piercing Arrow] was still a trivial matter, if he injured these maids who were like sisters to Nangong Yunshan, then his sin would be great.

"My lord!" He Kun, who was in charge of prospecting, came back, and he said that he had a major secret to report to your lord!"

Just when Xin Yan was entangled by the maids and couldn't get out, Zheng Ming hurriedly came to the martial arts arena.

"yes? Well, I'm going to meet them. ”

Xin Yan was trying to find an excuse to slip away, and he was full of promises.

The maids were unwilling to stop them, so they had to let Xin Yan leave.

When Xin Yan arrived in the conference hall, He Kun was already there. He Kun was also captured by Xin Yan from the Scattered Cultivation League, and he was proficient in exploring ore veins, and Xin Yan asked him to take other mining cultivators and let them explore if there were any veins of star iron stone nearby.

Xin Yan saw He Kun's face excited, and asked, "Are you looking for Star Iron Stone and Flower Blue Manganese?" Star Iron Stone and Flower Blue Manganese are both second-grade ores, which can be used to refine second-grade puppets or merchant ships.

He Kun nodded and said, "We found Star Iron Stone and Flower Blue Manganese near Heishuize, and we also found this!"

As he spoke, he put a cyan mineral crystal the size of a grain of rice, the color was as bright as jade, but there was a cold light shining in the mineral crystal, like countless stars.

"It's ...... Xuanbing Qingyu?"

Xin Yan recognized it at a glance, this was a third-grade Xuanbing green jade. Xuanbing Qingyu is an excellent refining material, and its value is extremely high.

He Kun nodded and said, "According to the results of our exploration, Heishuize not only has star iron stone and cyanocyan manganese, but it is also very likely that there is a vein of Xuanbing green jade. ”

"Vein?"

Xin Yan's heart jumped violently when he heard this, if Hei Shuize had a vein of Xuanbing Qingyu, what a huge fortune it would be.

He Kun said: "I can't be wrong, with my more than 20 years of mining experience, it is very likely that there is a vein of Xuanbing Qingyu there. ”

Xin Yan patted He Kun's shoulder and said, "You have made a great achievement." With Hei Mizuze, we can do a big job. ”

As he spoke, he said to Zheng Ming: "Well, quickly inform Miss Nangong, well, there are Wenxiu and Huzi who will go with us and take Hei Shuize over." ”

......

He Laosan was the commander of the Aoki Trading House stationed in Heishuize. said that he was the commander, but in fact, there were only seven or eight people under his hands, and all of them were old, weak, sick and disabled.

At the beginning, he was greedy for a few more bonuses per month to guard Hei Shuize, so he applied to the comptoir to come and garrison here. Who knew that after I came, I found that this place was a barren land at all, and there was not even a single figure visible within a radius of hundreds of miles.

He finally completed his term of office and applied for a callback to the firm. Who knew that the deacon office of the firm would not approve it on the grounds that it could not find a more suitable candidate. He stayed here for twelve years, and he thought that he would live in Heishuize for the rest of his life. Who knew that a few days ago, an order came to him to prepare for delivery and wait for Xin Yan from Shuinan Lingyuan to come and receive it.

He Laosan was overjoyed when he heard the news, and he called all his subordinates up early, telling them to hurry up and prepare for delivery. Who knew that Xin Yan never came, which made him so anxious, for fear that Xin Yan would change his mind or his business would be ruined.

On this day, He Laosan was about to make an inspection according to the usual practice, but a disciple pointed to the sky and shouted: "The enemy is attacking!

He Laosan looked up and saw a group of small black dots appear in the sky.

The speed of the little black dot was extremely fast, and after only a moment, it was less than ten miles away from them. Only then did he see that a war force of about 20 people was rushing towards this side at high speed.

"Run!" and a group of his men were terrified and fled in all directions.

Although He Laosan was flustered, he did not run. Because he knows that if the other party wants to kill them, whether they run or not is like a bird.

In the blink of an eye, the opponent's war department fell from the sky, guarding a fairy-looking girl walking towards them, followed by a huge chariot behind the war department, and seven or eight cultivators were followed behind the chariot.

Only then did He Laosan see clearly that the word "Lingxiao" was written on the back of the opponent's battle flag. And the battle department under the girl is actually all sixteen or seventeen-year-old girls, among them there are only three or four condensing vein cultivators, and the rest are only in the foundation building period, but the flying swords in the hands of these girls are all four-grade.

He couldn't help but curse in his heart: "Don't you just accept a broken place where birds don't? Can you show off like this? Even the war department has brought it out." ”

Although he was annoyed in his heart, he didn't dare to show it on his face at all, he bowed his hand and asked, "Are the people who came from the Lingxiao Sect, Miss Nangong and Mr. Xin Yan?"

"Exactly!" Xin Yan jumped out of the chariot, saluted back, and said, "We came to handle the delivery procedures, please cooperate with the senior brother." ”

He Laosan handed over a jade slip and said, "This is a delivery document. We have also packed up, and from this day forward, the black water will be yours. Farewell. As soon as the delivery was completed, he bowed his hand to Xin Yan and the others, and left without looking back. They didn't want to stay in Heishuizawa for a moment.

Xin Yan said to Nangong Yunshan: "Miss, you have to lead people to set up defenses outside, and He Kun and I will go to the mine to investigate." ”

Nangong Yunshan nodded: "You go! Leave the matter of defense to me." ”

Xin Yan pulled He Kun and jumped into the chariot and began to patrol the island, Hei Shui Ze was far bigger than they thought, and there were large areas of abandoned spiritual fields everywhere on the edge of Ze. The spiritual field here has obviously been abandoned for a long time, and all kinds of prohibitions in the spiritual field have been destroyed

"The mine is ahead!" said Xu Jue, suddenly pointing to a dark and deep ravine in front of him. Xin Yan followed his gaze and saw that there were mountains of ore waste piled up everywhere on both sides of the road, and the surrounding mountains were all gray and black, and even the small river in the ditch was also black......

"The mine is ahead!" Suddenly, He Kun pointed to a dark and deep ravine in front of him. Xin Yan followed his gaze and saw that there were mountains of ore waste piled up everywhere on both sides of the road, and the surrounding mountains were all gray and black, and even the small river in the ditch was also black......

He Kun pointed to an extremely wide yard in front of him and said to him: "I heard that this is the former mine, and in its heyday, there were more than 2,000 cultivators digging ore here. He was a local cultivator, and he knew everything about this mine: "In addition to the main star iron stone, there are also more than 30 kinds of minerals such as tourmaline stone, yin wind stone, ghost crying sand and mythril, and almost most of the materials for refining merchant ships and puppets can be found here." But I didn't expect that there was a vein of Xuanbing green jade here. ”

Xin Yan nodded and said, "Let's go to the mine together!" As he spoke, he summoned Nirvana and the blue-eyed toad, and followed He Kun into the mine.
