"Little Brother Dulong, good news, good news!" When the sky was getting dark, Ou Yezi, who had gone out to explore the situation of the ore vein, ran back in a hurry.

"Brother Ou Yezi, is this a rich mine?!" Du Long also greeted him excitedly.

"It's better than a bonanza! Oh my God! This is not only a rare bonanza, but also a solid black iron mine!" Ou Yezi still couldn't hide the excitement in his heart, and replied excitedly.

"Solid Black Iron Mine?!" Du Long wondered.

"That is to say, in addition to a layer of soil several meters thick on the surface, there is a huge stone mountain wrapped inside! The entire stone mountain is full of ore rich in black ironite!" Ou Yezi continued to explain with the excitement in his heart suppressed.

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

"Walking in the Star Continent for decades, brother, I have seen a solid iron mine, I have never seen a solid black iron mine like this, it is unheard of at all!" Ou Yezi sighed: "The rarer the ore, the more difficult it is to form this situation!"

"It's really big this time! Relying on this solid black iron mine alone is enough to refine what it needs to supply all the legions of the entire empire!" Du Long muttered to himself.

"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 Ou Yezi, please control your disciples, don't spread the news!"

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

"In this way, only a few of us know about this!" Du Long glanced at the people around him: "Xiaofeng! You and Qinglian are the same! You can't leak the situation here! Especially Xiaofeng, you'd better not even reveal it to the emperor for the time being! Don't worry, when the time comes, I will find a way to make up for the loss of the empire!"

"Well, don't leak this matter! When you can save it, all cats and dogs ask your father for the Black Dark Iron Ore, so aren't we at a big loss?!" Huo Feng obviously understood the truth.

"That's right! From now on, the area within a radius of ten miles of this mine must be strictly controlled, and no outsiders are allowed to enter and leave at will, and all the 1,000 men and horses brought here will stay and be responsible for the security and defense work here!" Du Long said with a serious face: "Also!Brother Ou Yezi! The second secret weapon structure map I handed over to you last time, you have to step up your research and manufacturing, and it is best to use the black iron ore here to make a small batch of that kind of secret weapon as soon as possible!"

"No problem! If you don't say it, brother, I've already had itchy hands!"

In the next few days, the Black Iron Mine began to undergo major construction, and a garrison barracks and an arsenal factory were built at the same time!

The Armory Factory was finally selected in a large cave at the bottom of the mine, and this natural giant cave is perfect for the Weapons Factory, which can directly mine ore from the cave and use it to refine the raw materials of black black iron, and also expand the scope of the cave!

The garrison camp was set up outside the cave, a camp built of a wooden fence, surrounded by an area of several miles outside the cave, and thousands of soldiers worked together, which was needless to say!

For several days, Du Long walked around the camp and instructed the soldiers on how to build a more advanced camp under the instructions of the Ring Spirit.

As for the construction of the inside of the cave, he didn't have the right to intervene, but when Ou Yezi built a decent weapon forging production line, the spirit girl couldn't help but put forward a few more suggestions, and Du Long was responsible for conveying them.

After Ou Yezi listened to Du Long's suggestion, his eyes lit up on the spot, and he immediately decided to modify several positions on the calcination assembly line according to his suggestion, so that the date of calcination production had to be delayed for a few days, and Ou Yezi didn't care about it at all!

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

When Du Long didn't have any suggestions for the construction inside and outside the cave, he said hello to 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 took Du Long and the two beauties to the edge of the swamp area smoothly, Du Long communicated with the Ring Spirit Beauty for a long time along the way, and only after arriving here did he speak: "Okay! Xiaofeng, Qinglian! Now it's only the three of us here! I have something to say to you clearly!"

"What's the matter!" ...... mysteriously" Princess Huofeng replied with a curious and puzzled expression, Xia Qinglian's beautiful eyes blinked lightly, although she was a little curious, she didn't say anything, just listened quietly on the side.

"I believe you feel it too! There are many secrets in me, but these secrets can't be told for the time being!" Du Long pondered for a long time, and then continued: "I hope that when you go with me to do anything thrilling, you can keep secrets! Also, I will tell the secrets that can be said, and the secrets that cannot be said for the time being, I hope you don't ask about them!"

"Everyone is your fiancée! Is there any secret you can't tell?!" Princess Huofeng pouted with some dissatisfaction.

"Alas, Xiaofeng, many secrets can't be told for the time being, and I will definitely tell you all when the conditions allow in the future! I know that you, a guy with a particularly strong curiosity, are the most difficult to deal with! If you can't do it, I have to send you back to the camp!" Du Long smiled helplessly.

"Okay, okay! Since the husband has said so, the family has promised that as long as it is a secret that cannot be answered, you can not answer others, but there is one thing you must do!" As soon as Princess Huofeng heard that she was going to send her back, she immediately compromised.

"What must be done?!" Du Long wondered.

"You are allowed to have other secrets! But as long as it is a secret related to other women, you must tell it honestly! Otherwise, you will have a secret in the future, and you will ...... outside" Princess Huofeng said what she thought in her heart, and before she could finish speaking, she was interrupted by Du Long!

"I see! I will definitely do this, in fact, apart from you and Qinglian, I Du Long don't want to have anything to do with other women in my life!" Du Long sighed with a smile.

"Hehe, it's hard to say, it's just that you haven't met a woman who really makes you feel tempted!" Huo Feng smiled disapprovingly.

Growing up in the palace, she has long been accustomed to seeing men's three wives and four concubines, liking the new and hating the old, and asking him to believe that men will always be consistent with women, it is better to let her believe that it is easy for sows to go up trees!

"Whether you believe it or not! In short, I, Du Long, promise here today that as long as there is a problem about women, I will be honest!" Du Long could only say helplessly: "Okay! Sit down, no matter what happens next, don't ask, just watch, and don't leak it out! Especially Xiaofeng, what happened with me, don't tell your father and mother!"

"The gods are chattering, people don't believe that you have any big secrets......" Princess Huofeng just said halfway through her words, she exclaimed in disgrace: "Ah......"

It turned out that just when she was nagging endlessly, the big lion suddenly rose into the air after receiving Du Long's instructions, and flew straight to the inside of the swamp, within a radius of dozens of miles, under the monitoring of the spirit beauties, there was no trace of human beings at all, and he was not afraid of revealing secrets!

"This ...... How is this possible?!Xiao Lie actually has the strength of the spirit rank?!Oh my God......" In mid-air, after Princess Huofeng recovered from the initial fright, she immediately whispered in disbelief.

"Xiao Lie, say a few words!" Du Long said with some amusement.

"Yes, master, what do you want me to say?!" In mid-air, Xiao Lie's pretended stupid questioning voice sounded.

"Oh my God! it's true......" Princess Huofeng exclaimed again, and although Xia Qinglian, who was hugging Du Long's back tightly, looked surprised, she didn't say anything more.

"This ...... What the hell is going on?!Du Long!Tell people, what the hell is going on?!Spirit level demon beast?!How did you become your spirit beast?!" Princess Fire Phoenix muttered to herself with some nervousness.

"Now you know how much of a sensation it will cause if there are many secrets that are revealed, right?!" Du Long replied with a smile.

"I'm afraid that no one in the three empires has a spirit level spirit beast! If this is known by outsiders, it will definitely cause a sensation all over the world! Du Long, oh no! Husband...... "Huo Feng began to coquettishly say: "Tell people quickly! What the hell is going on?!"

"The reason I said before, at that time, Xiao Lie was fighting with a crocodile demon, and he was about to be defeated, and it happened that I accidentally got an elixir that could help it recover from its injuries at the same time, and at the same time, it would increase its strength and defeat its opponent!

"Oh my God! An elixir that can play a role in the battle of a spirit-level demon beast, how advanced does that pill have to be to do it?!Where did you get it?!Don't tell me it fell from the sky!" Princess Huofeng said in disbelief.

"I really guessed it again! I found this elixir in the space ring that fell from the sky!" Du Long replied with a smile.

"This ......" Princess Huofeng froze on the spot, Du Long's answer was very reasonable, and she didn't know how to refute it for a while.

"Alas, stupid Nizi! Believe it or not, in short, the result is like this! You have to remember what we just agreed, don't break the casserole and ask to the end! Also, don't tell me that Xiao Lie is a spirit-level demon beast!" Du Long sighed.

"Oh! I understand, of course I know the seriousness of the matter, this matter must not be said!" Although Princess Huofeng was full of question marks, she could only accept Du Long's explanation, who made her already have three chapters of the law just now!

"Actually, there is another thing you don't know, if I hadn't subdued Xiao Lie in the first place, we would have been wiped out on the way to the third gold mine!"

"What's going on here! Come and hear it!" As soon as Huofeng saw that there was a story to hear, he immediately became energetic.

So, Du Long roughly sent two fourth-order spirit beasts from the Fan family to ambush in Shuangzigou, preparing to kill a group of his own people, but in the end, Xiao Lie made a move and killed all the opponents.

"Oh my God! No wonder when we passed by Shuangzigou, we saw a lot of fresh human bones along the way, it turned out to be like this! No wonder you didn't let your subordinates find out the origin of those human bones at that time!" Princess Huofeng suddenly realized.

All kinds of new plots,All kinds of climaxes have been launched one after another,Brothers and sisters,Recommend adding a collection! More motivation! Yesterday there was no collection.,It's a bit like talk.
