Xuantian Dragon Zun

Leading a large group of people, they rested for a night on the way, and arrived at the mine area mentioned by the Wu family brothers at noon the next day. No monsters along the way dared to harass this human team. The reason was that the big lion under Du Longzuo, That is the existence of the spiritual rank (fifth rank), and ordinary monsters feel his aura from a distance and are too frightened to move, so how dare they come to seek death!

Looking at the thousand-meter-high mountain in front of him, with a lot of dark ore exposed on the hillside, Du Long couldn't help exclaiming: "It can't be such a big black black iron mountain? If so, light The black black iron ore from this mountain is enough to build a million-strong army of metal ore!"

Ouyezi on the side shook his head and replied: "It depends on whether the black iron ore here is rich or poor. If it is poor ore! Even if there is such a large mountain of reserves, it is not enough to equip an army of 100,000 horses!"

"Isn't it?" Du Long didn't dare to say: "The reserves of such a big mountain are not enough to equip a legion of 100,000 horses?"

"Yes! After all, this is relatively rare black black iron ore, no more than ordinary steel ore! The metal content in the ore is relatively many times less!" Ou Yezi nodded and continued: "However! According to my visual inspection, This should be a rich mine, and the efficiency of refining black black iron will also increase a lot!"

"Haha! That's good! What should we do now?" Du Long replied excitedly.

"I'll arrange manpower to detect the specific situation of the ore veins, and you arrange personnel to start stationing and be responsible for vigilance by the way! I suggest that for the sake of confidentiality, you can set up the weapon factory directly here! At that time, you will mine the black black iron ore and refine it at the same time. , and can forge all kinds of weapons at the same time! Therefore, it is best to designate the ten-mile radius of this mountain as a restricted area, and prevent outsiders from approaching at will!" Ou Yezi reminded.

"Okay! It's exactly what I want!" Du Long stopped talking nonsense, and directly confessed to Sun Lin: "Sun Lin! Immediately arrange for people to set up camp! The key task in the future is to designate the ten-mile radius of this mountain as a restricted area! "

"Your subordinates obey!" Sun Lin responded, and went to work, and Ou Yezi was not idle, and began to lead his group of disciples to conduct a careful investigation of the black black iron veins in this area!

Du Long rode the big lion and wandered around seemingly leisurely. In fact, he let the big lion leave its own unique atmosphere in this area, showing those low-level monsters that this area is already the territory of spirit-level monsters. , from now on there will be no blind monsters invading rashly!

"Brother Du Long! Good news, good news!" Ou Yezi, who went out to check the situation of the mine veins, ran back excitedly when the sky was getting dark.

"Brother Ouyezi! Could it be that this is a rich mine?" Du Long greeted him excitedly.

"Better than a bonanza! My God! This is not only a rare bonanza, but also a solid black black iron mine!" Ouyezi replied excitedly, still unable to hide his inner excitement.

"Solid black iron mine?" Du Long asked puzzled.

"That is to say, in this entire mine, except for a layer of several meters thick soil on the surface, there is a huge rocky mountain wrapped inside! The whole rocky mountain is full of ores rich in black iron ore!" Ou Yezi suppressed the excitement in his heart and continued to explain road.

"My God!" Du Long finally understood, and immediately exclaimed: "If there is solid black black iron ore in such a mine, how much black black iron can be mined?"

"I have been walking in the Star Continent for decades. I have seen solid iron mines. I have never seen such a solid black iron mine. It is unheard of!" Ouyezi said with emotion: "The rarer the ore, The more difficult it is to form this situation!"

"This time it's really big! Just relying on this solid black black iron mine, it is enough to extract what is needed to supply all the legions of the entire empire!" Du Long murmured.

"No! Such a big secret must not be passed on!" Du Long quickly realized the seriousness of the problem, and immediately made a decision: "Brother Ouyezi! Please control your disciples and don't spread this news. go out!"

"Of course I understand this old man! Except for me and Lu Hai, the other apprentices don't know about this!" Ou Yezi also calmed down now.

"In this way, we are the only ones who know about this!" Du Long glanced at the people around him and said, "Xiaofeng! The same goes for you and Qinglian! Don't leak the situation here! Especially Xiaofeng , you'd better not even reveal the emperor's side for the time being! Don't worry, when the time is right, I will find a way to make up for the loss of the empire!"

"Well! It's better not to leak this matter! If you can save time, all cats and dogs will ask the father for black black iron ore, so we are not at a big loss?" Huofeng obviously understands the truth.

"That's right! From now on, the ten-mile radius of the mine must be strictly controlled, and no outsiders are allowed to come in and out at will. All the 1,000 troops brought this time will stay here and be responsible for the security defense work here!" Du Long said with a smile on his face. Seriously, he said: "Also! Brother Ouyezi! The second secret weapon structure diagram I gave you last time, you have to step up research and manufacture. It is best to use the black iron ore here to manufacture it as soon as possible. A small batch of that secret weapon!"

"No problem! If you don't tell me, brother, I've already had itchy hands too! Hehe!" Ou Yezi replied with a smile.

In the next few days, the Heixuan Iron Mine began to undergo major construction, and a garrison barracks and a weapons factory were started at the same time!

The weapon factory was finally selected to be in a large cave at the bottom of the mine. This natural huge cave is perfect for a weapon factory. You can mine ore directly from the cave to refine black black iron raw materials and expand the size of the cave. scope!

The garrison barracks was set up outside the cave, a camp made of wooden fences, surrounded the area several miles outside the cave, and thousands of soldiers fought together, so the efficiency is needless to say!

In the past few days, Du Long patrolled around the camp, and under the instructions of the ring spirit beauty, he taught the soldiers how to build a more advanced camp. He was extremely busy.

As for the construction inside the cave, he didn't have the right to intervene. However, after Ou Yezi built a decent weapon forging production line, the ring spirit beauty couldn't help but make a few more suggestions, and Du Long was in charge of conveying them.

After hearing the suggestion conveyed by Du Long, Ou Yezi's eyes lit up on the spot, and he immediately decided to modify several positions on the forging assembly line according to his suggestion. As a result, the date of forging production had to be delayed by a few days. Regarding this, Ou Yezi I don't care at all!

According to his understanding, sharpening a knife is not a mistake in chopping firewood! Make full preparations today, and when you recruit a group of blacksmiths to help in the future, your apprentices will be much more relaxed, and the efficiency of forging weapons will be increased many times!

When Du Long had no more suggestions on the construction inside and outside the cave, he greeted Ou Yezi and Sun Lin at the request of the ring spirit beauty, and rushed towards the swamp area not far away!

The big lion led Du Long and the two beauties to the edge of the swamp area smoothly. Du Long communicated with the ring spirit beauties for a long time, and only after arriving here did he say: "Okay! Xiaofeng, Qinglian! Now only The three of us are here! I have something to tell you clearly!"

"What's the matter! It's so mysterious..." Princess Huofeng responded with curiosity and doubts on her face. Xia Qinglian blinked her beautiful eyes. Although she was a little curious, she didn't say anything more, she just listened quietly. .
