The broken dragon stone that blocks the mine is the last line of defense of the Yuquan mine, and the secret boulder mechanism can completely close the passage, and hundreds of thousands of catties of boulders are enough to make the supernatural powerhouses helpless, and it can also make the defenders who retreat to the mine hold on until the arrival of reinforcements.

It is precisely for safety reasons that there is only one exit from the Yuquan mine, and once it is closed for a short time, it is impossible to get out unless a lot of manpower and material resources are used to dig out the passage from the outside.

Therefore, Qin Yun said that he was going to go to the sect alone to report the news, which made Elder Zuo extremely puzzled, and thought that he had heard it wrong.

Qin Yun said, "I have a small supernatural ability that can teleport out. ”

Qin Yun relied on the Qiankun Shifting Divine Power that he had recently mastered, although the mine cave closed by the Broken Dragon Stone was quite long, he could continuously use this Divine Ability without worrying about being trapped in the rock and suffocating to death.

"Little Shifting!"

Elder Zuo thought that he knew about Qin Yun's supernatural ability, and he was even more surprised in his heart.

Whether it is a martial artist or a qi refiner, as long as he is promoted to the realm of Huagang, he can comprehend a small magical power through unremitting efforts, and the small transfer technique is one of the very powerful abilities, whether it is used in battle or escape, it is extremely practical.

Elder Zuo's own comprehension of the small supernatural ability is called Vajra Support, which can turn his body into a metal body of copper skin and iron bones within ten breaths, which is enough to resist the full attack of a strong person of the same level.

If it weren't for this supernatural ability, he would have died by his opponent's sword in the morning battle.

Although the Vajra Support is a very good supernatural ability, it is still a step inferior to the small transfer technique, and Qin Yun was able to comprehend this rare supernatural ability, which also made Elder Zuo couldn't help but look at him with admiration.

You must know that the level of comprehension ability is closely related to the talent potential of the martial artist!

"If you want to go, go at night!"

Elder Zuo's heart was determined, and he said without hesitation: "The enemy is strong. If you leave now, it will be too easy to be discovered, and once you are encircled, it will be difficult to get out. ”

The Wu Clan and the Yangming Sect dispatched at least four Huagang powerhouses, although one of them died in the dock fort, but the remaining forces had no problem dealing with Qin Yun alone.

Qin Yun was already extremely lucky to be able to break in under the heavy siege of the enemy, and it was undoubtedly even more difficult to break through, especially during the day.

Qin Yun nodded, he was not arrogant to this point.

With the wine, food, and elixir talismans that Qin Yun had taken out, the dozens of Sword Sect disciples who had retreated to the mine were finally able to relax and begin to treat their injuries or regulate their luck.

Rumble!

All of a sudden. The inside of the mine shook for a while, countless gravel splashed down from the top of the cave on the mountain wall, and there was a thunderous sound from outside, and the sound was extremely amazing.

What's going on? Everyone couldn't help but look at each other.

Elder Zuo, who was healing his wounds, opened his eyes, and his eyes shone with a cold light. He said in a deep voice: "They are breaking the mountain and opening a hole, they must have used the thunderbolt bomb of the Yangming Sect!"

The faces of many disciples changed suddenly, they didn't expect the enemy to be so fierce, they wanted to enter the mine as soon as they captured the dock fort, and even did not hesitate to use precious thunderbolts.

"Don't worry, it's not so easy for them to dig here!" Elder Zuo sneered, "If they really break through the mountain and come in, we will have to retreat to the mine and hide." ”

The Yuquan Mine has a history of hundreds of years of mining. The inside of the mine has long been dug out of the dense tunnels like spider webs, many leading to extremely deep underground, dozens of people casually find a corner to hide, trying to find it is tantamount to looking for a needle in a haystack.

Elder Zuo said, "We don't need to ignore them. But we can't be unprepared, everyone should seize the time to recover their strength and be ready for battle at any time. ”

The disciples of the Sword Sect nodded in unison, although there was movement from outside one after another. But it can no longer affect them.

At this moment, Qin Yun was idle, and his strength was not damaged or injured. No healing is required.

His eyes fell on the minecarts parked on wooden rails, which were specially used to transport ore, and with the help of rails laid on the ground, they could carry thousands of pounds of ore to the entrance of the cave at a time, which was very time-saving and labor-saving.

There were more than a dozen minecarts parked in the long mine road, and the ore stacked in the body was of different colors, Qin Yun's heart moved, and he walked over and grabbed a piece of black ore from a minecart, and the amount of ore was very heavy.

"This is the dark iron ore," the gray-clothed sword cultivator said, "Most of the dark iron needed for the sect's casters is excavated and refined from here, and this cart of ore is worth dozens of spirit jade." ”

Xuan Tie?Qin Yun's eyes flashed, and he immediately had an idea in his heart.

He stretched out his hand and pushed the minecart to the ground, and the ore weighing thousands of pounds suddenly rolled to the ground.

The gray-clothed sword cultivator was stunned for a moment, not understanding what Qin Yun wanted to do, only to see that Qin Yun had also knocked down the second minecart, but this minecart was loaded with spirit jade ore.

He sat between the two piles of ore, took a piece of dark iron ore and held it in his hand, and silently used the Jiuyang Divine Skill to urge the innate true gang, and the scorching red flame suddenly burst out in his palm!

Qin Yun's cultivation of the Nine Yang Divine Skill is the supreme heart method of the Yang to the Strong, the Gang Fire catalyzed by the Innate Zhenggang is extremely violent, under the calcination of the Gang Fire, the Xuan Iron Ore quickly turns red and soft, and a large number of impurities are refined clean, leaving a mass of molten iron that has shrunk many times in size.

Immediately after that, Qin Yun grabbed the second piece of ore with his left hand, and concocted and refined it in the same way, and the molten iron smelted and the one in his right hand fused with each other, and then the third, fourth, and fifth pieces

It wasn't until the tenth piece of ore was refined, the dark iron in Qin Yun's right hand was almost seven or eight times the size of the original, and the molten iron that had gathered together under the control of his Gang Qi slowly elongated, changing at a speed visible to the naked eye.

Eventually, a shiny black arrow appeared, with a sharp, three-edged arrow, a straight shaft, and two thin tails!

The gray-clothed sword cultivator next to him was dumbfounded.

What Qin Yun demonstrated was clearly a means of forging weapons, and forging weapons without the help of tools such as refining furnaces, casting hammers, etc., was an ability that only a great caster could have.

Moreover, the dark iron material is hard and extremely difficult to melt, even if it is an innate master, it cannot be refined with true fire, and the strong person must also master a mental method to promote the fire, otherwise he can't do it.

He had heard that Qin Yun's swordsmanship was extremely skillful, but he had never heard that Qin Yun also knew how to refine weapons.

Sure enough, the capable person is omnipotent, and the gray-clothed sword cultivator admires Qin Yun so much at this moment, you must know that even in the Yuquan Mine, no craftsman has such a means.

However, the gray-clothed sword cultivator overestimated Qin Yun's ability in refining weapons.

Qin Yun is not the kind of pure sword cultivation who has nothing but a sword, in addition to the two divine weapons of Tianwen and Juque, he also has the Sunset Divine Bow, as well as various talismans that he has refined, all of which can play a role in battle.

Especially the Sunset Divine Bow, Qin Yun had the ability to kill opponents from a distance, but after the original wind-chasing arrows of the Sunset Divine Bow were exhausted, the ordinary three-edged armor-piercing arrows were gradually unable to meet his needs.

Although Qin Yun could order better arrows from the sect's forgers, the best forgers in the sect were not willing to devote time and energy to refining small arrows, their usual tasks were already extremely many, and Qin Yun did not have enough weight for them to make a move.

There are a large number of commonly used arrows and weapons sold in the shop, but Qin Yungen can't look at it.

So in such a situation, he gave up the idea of asking for help from the sect's casters and tried to refine the arrows himself.

With the all-knowing power of Star Spirit, Qin Yun didn't even need to spend the sect's contribution in exchange for the method of urging the Ganghuo and Ganghuo Refiner, and he had mastered a lot of experience through his own exploration.

It's just that because most of his time is still spent on cultivating Jiuyang Divine Skills and swordsmanship, plus his recent frequent missions to the sect, he has put down the matter of refining arrows.

Now trapped in the mine, there are a lot of ready-made materials at hand, so I have an idea to see if I can refine a few suitable dark iron arrows.

With Ganghuo direct refining, refining ore in front is very simple, as long as the strength is enough and you know how to promote Ganghuo, you can successfully master it after a few practices, but the most important casting step in the back is very difficult.

Casting is the embryo shape of the weapon that is refined, and in the case of not applying tools, relying purely on Gang Qi to control, the requirements must be extremely high, and Qin Yun didn't know how many times he failed when he first started.

Fortunately, he is not refining a sword weapon with a complex structure and large volume, and the arrow has a simple structure and relatively small size, so it is much easier to control.

The techniques of refining, shaping, refining, and reshaping Qin Yun became more and more proficient, and one after another Xuantie arrows were constantly completed in his hands, and soon a pile was piled up in front of him.

He took care of himself and refined himself, but the disciples of the Sword Sect next to him were all admired, and many of the Sword Sect disciples who had been stationed in the Yuquan Mine for a long time knew how to cast, and they knew very well the difficulty of Qin Yun's hand.

After refining thirty Xuantie arrows, Qin Yun stopped his luck and breathed to recover the huge amount of Qi he had consumed.

When his strength was almost restored, he took out the talisman knife and spiritual materials from the Qiankun space, picked up a dark iron arrow, and carved a talisman on the shaft of the arrow with the knife!

A gasp suddenly sounded around them, and those Sword Sect disciples were all dumbfounded, and they couldn't believe their eyes.

Refining arrows is just fine, and casting tools can be regarded as "rough work" in a sense, but refining talismans is absolutely "fine work", and what Qin Yun is doing now is fine.

The usual talismans are carved on spiritual materials such as spiritual wood and spiritual jade, and the general talisman plates are square and round, but at least there is a lot of area for falling knives.

And how thick is the shaft of an arrow, and how difficult is it to carve complex talismans on the shaft?

You can't imagine it!
