After having a clear location, Lu Feng did not hesitate any longer, and immediately led the five Saint King masters of Lu Bu, Ran Min, Huo Quzhi, Wei Qing, and Zuo Ci, as well as the six sword slaves, and 200,000 troops to the barren mountain.

To be honest, it was a huge problem for so many armies to climb over the barren mountains, but now Lu Feng didn't have a very good way.

For the Southern Yan Kingdom, there are only two ways to attack the Aoxiang Kingdom.

Either attack from Dingxing Mountain in Red Maple City, or climb over the barren mountain.

Although the barren mountains are steep, as long as they climb over the past, the army will go directly to the hinterland of the enemy army, and the enemy who can be guaranteed to fight will not even know his mother.

"Your Majesty, this barren mountain is really a barren mountain, desolate everywhere, and you can't see too many trees. Lu Bu looked at the barren mountain and sighed lightly.

Lu Feng also nodded, this barren mountain is indeed a little strange, and he has never seen sparse trees on that mountain.

It's strange that this barren mountain is so big that the trees on it are hard to see.

But he didn't think much about it, these days, are there fewer strange things?

This crossing by oneself, this system, is the biggest strangeness.

"Hey, this is ......"

Suddenly, Zuo Ci's voice came.

Lu Feng and the others followed Zuo Ci's gaze, but they only saw Zuo Ci looking at a stone.

"Yuan Fang, what's so strange about this stone?" Lu Feng looked at the stone, but he really couldn't see anything strange.

The only difference is that the stone has some green on it, similar to moss.

Zuo Ci stared at the stone, with some excitement in his eyes, and said, "Your Majesty, please wait for me for a while, and I will come back immediately." ”

After speaking, Zuo Ci's figure flashed and left quickly.

"What is this Zuo Ci doing?" Lu Bu frowned slightly, and said, "The first task of the army now is to climb over the barren mountains, and now that they are stopping here, what are they doing wasting their time?"

Lu Feng groaned slightly, and said: "Seeing that Yuan Fang was a little excited just now, he should have found something interesting, Feng Xian, you give the order to go down, let the army rest on the spot, recover its strength, and then continue to move forward." ”

"Yes!" Although Lu Bu was a little puzzled by Zuo Ci's behavior, he still carried out Lu Feng's order.

And Lu Feng, looking at the stone again, really couldn't see anything different, shook his head slightly, and didn't think about it anymore, waiting for Zuo Ci to come back.

After a while, Zuo Ci came back, his face was full of excitement, and said, "Your Majesty, great joy, great joy, great joy!"

"Daiki?"

Lu Feng looked at Zuo Ci strangely, and asked with a smile: "What is the great joy? Could it be that you have already killed the Saint King master of the Spirit Sword Sect?" haha......

He's just joking.

But Zuo Ci was very excited, and said, "Your Majesty, this matter is even happier and exciting than killing the Spirit Sword Sect Saint King master. ”

"Oh?"

Lu Feng was taken aback, stared at Zuo Ci, and asked, "What's even more exciting than killing the Spirit Sword Sect's Saint King master?"

"Your Majesty, please come with me. ”

Zuo Ci said with excitement on his face.

Lu Feng nodded, and followed Zuo Ci, behind him, the six sword slaves followed closely, and Ran Min Wei Qinghuo also followed, they were curious about what Zuo Ci's mouth was about killing the Spirit Sword Sect Saint King master.

Only Lü Bu remained where he was, guarding the army.

Following Zuo Ci for a distance, Lu Feng, the Six Sword Slaves and Ran Min arrived at this place.

There is a cave here, the cave is steaming, and the true qi is lingering, it is the true qi breath in Zuo Ci's body, obviously, this cave was made by Zuo Ci.

"Yuan Fang, what do you mean by this?" Lu Feng looked at Zuo Ci strangely.

"Your Majesty, please come with me. ”

Zuo Ci took out a bright night pearl and took the lead into the cave, and Lu Feng immediately followed with the Six Sword Slaves and Ran Min.

The cave is not very deep and comes to an end in less than two minutes.

But on the mountain wall at the end of this, there are fluorescent streams, and these fluorescent dark greens flow on the dodge, and they look a little beautiful.

"This is ......" Lu Feng was a little puzzled, thought about it, and threw a probing technique on it, wanting to see what it was.

Before the information of the exploration technique came, Zuo Ci said excitedly: "Your Majesty, this is a refined iron stone, which is very precious, and it is an excellent treasure for refining weapons. ”

"Especially the 10,000-year-old refined iron stone, it is rumored that it can even refine heaven-level divine weapons. Even if it is the most ordinary refined iron stone, the forged weapon will be much stronger than the ordinary weapon, and it is no exaggeration to say that it is also a big knife, and the big knife forged by fine iron stone can easily cut off the ordinary iron and stone refining big knife!"

The more Zuo Ci spoke, the more excited he became, and said, "Your Majesty, if we can have a group of powerful refiners under our command to forge all these refined iron stones into weapons and equip the soldiers under our command, then the combat effectiveness of the soldiers under our command will be very terrifying. ”

"Especially the trapped camp, with the strong combat effectiveness of the trapped camp, coupled with this powerful weapon, the minister can say with great certainty that the combat effectiveness of the trapped camp will definitely not be inferior to the ace army of those dynasties!"

When Zuo Ci said this, the information fed back by Lu Feng's exploration technique also arrived.

It is exactly the same as what Zuo Ci said, fine iron stone, forging weapons, and refining the best materials for divine weapons.

Lu Feng was also very excited and excited.

If you can forge these refined iron stones into weapons and equip the army under your command, especially the trapped camp and the Tiger Guard, then do you still need to worry about the armies of the Bailan Kingdom and the Jinshui Kingdom?

Push it straight over!

Your weapon is powerful, cut your weapon with a knife, but see how you can fight!

However, the big problem is that the information fed back from the exploration technique shows that the refined iron stone is very difficult to refine, and it must be refined by a refiner of the human level and above.

Moreover, a high-grade refiner can refine two or three pieces of refined iron stone in a day, which is barely enough to forge a war knife suitable for soldiers.

With this restriction, it is basically too difficult for Lu Feng to let his army be equipped with war knives forged from iron and stone on a large scale.

The status of a human-level high-grade alchemist is not below that of a human-level high-grade alchemist, and his identity can be regarded as precious.

In the entire Southern Yan Kingdom, I have never heard of a high-grade refiner, and it is simply impossible to forge a large-scale battle sword.

Zuo Ci looked at the fine iron stone in front of him and said, "Before, I also wondered why this barren mountain was bare, and even the trees were difficult to see. ”

"I only reacted when I saw the dark green stone unique to the refined ironstone mine before, this barren mountain may be a refined ironstone mine, ordinary trees can't survive on it at all, and now I see that this is the case, no wonder this place is bare. Just ......"

PS: The power outage didn't come until ten o'clock, and only two chapters have been written so far, and they were sent out immediately, and the rest ...... Looks like I'm going to have to code all night tonight. Alas, power outages are really deadly, especially for writers like me who don't have a manuscript......
