Seeing a few familiar black stones, Hai Wu was at first at a loss, and then had deeper suspicions, black stones can be used to forge weapons, of course she knows, the Ministry of Naval Weather has also tried, polished and refined, and made into weapons and equipment.

However, the armor leather of the blackstone weapon is too brittle, and it is not as good as the bones of the fierce beasts, how can it be harder than the bronze? She seriously doubted the authenticity, and suddenly thought of the refining of bronze, and asked, "Do you want to add something?"

"No, I don't. Mu Huo replied with a smile, smelting, slagging, and reducing these extremely pure iron ores, and after three refining, more than 30 catties of iron ore remained, and only 20 catties were left, which became pig iron.

When the ore cooled down, the sea witch looked at the nature, and it was indeed much stronger than the one they refined, but compared to the bronze tool, it was still not good, right?

She didn't speak, only showed an inquiring gaze, and Mu Huo didn't speak, but continued to refine it in the furnace, after four refining and five refining, it can be equal to crude bronze, and after six refining, it can be compared with fine bronze.

After the seventh refining, it can already be compared with high-quality bronze, and after the eighth refining, even compared with the new bronze, it is no longer the same, and when it comes to the ninth refining and tenth refining, it completely surpasses the bronze, and has changed from pig iron to wrought iron.

Whether it is hardness, toughness and strength, they are far above the new bronze, at this time, there are only fifteen catties of wrought iron left, Haiwu is so surprised that he can't close his mouth, he didn't expect that such a black stone can really become better than bronze.

The wood fire did not stop, continued to purify and forge, fifteen refining, twenty refining, the wrought iron in his hand, in the end, only twelve catties remained, he cast it into a harpoon, and gave it to Hai Wu, who couldn't put it down.

Compared with the Ministry of Weather, it is obviously safer and more convenient to purchase goods from the Ministry of Weather, which is also conducive to accelerating the integration of the two departments, strengthening the relationship between the two departments, and pulling the Ministry of Weather on the ship, which is also more in line with the interests of the Ministry of Wood Weather.

No accident, later, Haiwu agreed to this matter, and was willing to use the iron ore rough to trade wrought iron with the Muhou Ministry, in her opinion, iron ore is not a holy mine, even if it is discovered by the Wind King Ministry, it is not so dangerous.

The exchange ratio is four to one, four catties of raw ore, one catty of wrought iron, the normal refining ratio is two to one, but the wood waiting department can not be refined, for the sea waiting department, it is relatively easy to find ore on the bottom of the sea.

The affairs of the island, the wood fire is also shared with the sea witch, the jungle and the coast, there are people from the Wind King Department, refining with great fanfare, which is easy to cause trouble, and when it comes to the sea, the secrecy will be higher and the risk will be reduced.

Seeing that Mu Huo was so honest, Hai Wu couldn't hide it anymore, and basically told him many things about the Haihou Department, such as the secret method he was more interested in walking in the water, which was their scales.

Their fish scales, which secrete aroma in the water, disguise themselves as the same kind of other sea beasts, and have a similar effect to animal avoidance powder, and have a wider range, higher effectiveness, and longer duration, but unfortunately they can only use it themselves.

The fist-sized Pearl King, the night pearl as bright as fire, the combustible ice with rich calorific value, and the extremely pure fire phosphorite, began to trade with the Wood Waiting Department, and frankly told them that they had raised a strange beast sea mussel.

After the wood fire informed the island, the pattern of the eastern seas, the area ruled by the alien beasts, and the black cat hidden in the headquarters, the sea witch was silent for a moment, and also told a secret of his own.

After advancing three thousand miles from the coast of the mainland to the north, there is still a vast area, where it is inaccessible and cold all year round, and it is also a paradise for giant beasts, with iceberg-like sea lions and giant peak-like winged beasts.

On the edge of that coast, there is another garrison of the sea people, there are more than 20,000 sea people stationed, there are twenty ability warriors, and even two late warriors, raising two alien beasts, a blue whale, and a white turtle.

In other words, the true strength of the Sea Weather Division, there are more than 40,000 Sea Clans, forty Ability Warriors, four late-stage warriors, and one Great Witch, and in terms of overall strength, it has surpassed the original Wind King Department.

It's a pity that they don't have a witch king, or a king at the peak of the late stage, so the Sea Weather Department will definitely not dare to expose it, and even ordinary ability warriors don't know about it, only the middle and late stage warriors can know about it.

Seeing that Mu Huo was so honest, she couldn't hide it anymore, because the secrets of the Mu Hou Department and the secrets of the Sea Hou Department would lead to death, and Hai Wu was in a complicated mood, but she just didn't want to owe him.

When he first heard about this, Mu Huo was also shocked to lose his teeth, the Haihou Department had such a background, and at the same time, he was secretly glad in his heart, thanks to him choosing to be a friend, not an enemy, otherwise, the Mu Hou Department would have to face the four royal departments.

Originally, he told these secrets to Haiwu, and the more important reason was that the strength of the Maritime Waiting Department was far inferior to that of the Wood Waiting Department, even if he had a strange mind, he still had enough strength to suppress and avoid disasters.

Who knows, the Ministry of Maritime Weather is even deeper than them, which really makes Mu Huo embarrassed, and at the same time, he is vigilant in his heart, but he is relieved to think that Hai Wu is willing to tell him frankly even such a secret......

......

In 214, Muhuo and Haiwu marched to the eastern islands, and the troops of the Maritime Weather Department also began to settle on the islands to mine the ores on the seabed.

Fortunately, what made Mu Huo worry did not happen, and the two were safe, playing chess, making tea, drinking, fishing, embroidering, chatting, holding hands, and having a very harmonious relationship, but they left him aside.

I saw the young man of Mu Yu's family, Mu Yu is over sixty years old, and the little guy of his family has just passed the coming-of-age ceremony, he personally named Mu Yun, he is a strong warrior, but he is not a witch disciple.

The possibility of the witch disciple's awakening is too low, not a witch disciple, but Mu Yu is very happy, he has stayed at the limit of the flesh and blood warrior for more than ten years, and he has never been able to break through, with a sad face, lifespan is the biggest problem!

The innate awakening ability, of course, can make people, when they are in a low realm, master terrifying power, but in the later stage, it is more and more troublesome, and the most peak wizard is not as good as the most ordinary ability warrior.

Not to mention anything else, the lifespan alone makes people feel white, only by becoming a great witch can they survive to the end, but the difficulty of breaking through the great witch is no less than breaking through the late stage, the late stage of one hundred and fifteen, how harsh the requirements are.

So in Mu Yu's opinion, not being able to awaken the ability is a good thing, Mu Yun can become a warrior with the ability, and he can have a lifespan of three hundred years, which can be used to slowly improve, unlike him, he can't advance or retreat.

Subsequently, Wood Fire also went to the northern continent, and saw even more glacial scenery, and the tribesmen stationed in the Sea Weather Department hunted, fished and sanitized, and they also mined combustible ice, luminous pearls and fire phosphorrites.

The two departments often have contacts, and they have not broken off contact, but there are fewer personnel, and even the fishing nets that are traded, he has seen a lot, the ice prey is too thick, and it is difficult to pierce with ordinary weapons, but the hunting nets are better to use.

......

In 215, the Fengwang Department celebrated, and the six departments came to the dynasty, and the Wang Department issued an order to transfer troops, requisitioning 2,000 people from the Shihou Department, 5,000 people from the Earth Waiting Department, 3,000 people from the Ice Waiting Department, and 3,000 people from the Yanhou Department to attack the Gobi Desert.

As for the Maritime Weather Department and the Wood Waiting Department, they have not yet received the order, the desert is too far away from them, and the Maritime Weather Department is cold-resistant, but not drought-resistant, and if they are away from the water source for too long, they will be exhausted and unsuitable for fighting in desert areas.

After the celebration, Muhuo visited Maya, who was also forty years old, but she didn't have a partner yet, and she broke through to become a wizard, and now she is the law of the royal department, and her perception makes her never misjudge, and her reputation is extremely high.

The father and daughter didn't stay long, and received a message from the Wind King, Mu Huo came to the Wind King's palace, met a young concubine, walked out of the palace in disheveled clothes, he walked into the palace with the same face, and saw the Wind King again.

The Wind King was looking at a few things, there were agate, diamonds, crystals, iron ore, jade, and more sulfur, all of which were wood fire in the volcano, and she was looking through the items she had purchased.

"What do you want these things for?" the Wind King asked faintly when he saw him coming, returned to the messy couch and sat down.

"I just think it's interesting. Wood Fire replied quietly.

"Interesting, so much?" said the Wind King, playing with a piece of sulfur ore.

"It's used to repel insects, and the smell after ignition can disperse snakes and insects, and there are more insects in the jungle, which is very effective. Wood Fire replied.

The Wind King got up, swept past the wooden fire, walked to the gate of the palace, and gave a few orders to the guards outside the palace, and the guards departed, and in a short time they saw the guard, who came back with a large wooden box.

The box was opened, and a dense number of centipedes and scorpions crawled out, and the Wind King stood at the door, throwing the sulfur ore on the ground, using bronze to condense the sunlight, and ignite the sulfur, a pungent smell, and suddenly diverged.

She couldn't help but cover her nose, only to see those crawling insects, one after another in the direction away from the yellow smoke, quickly fled, the Wind King turned around, returned to the palace, and asked the guards to clean up the bugs and ores.

"The things are good, and my Wind King Department is also very useful, so bring more back next time." The Wind King returned to the couch.

"Yes!" Wood Fire nodded and reminded: "Burning smoke, try not to inhale, and when burning, don't put water around, the smoke will melt when it encounters water, and you will get sick after drinking it." ”

"Got it. The Wind King answered, patted the position next to him, and said loudly, "Come and sit down." ”

The wood fire did not move.

"Come here!" she said in an accentuated tone, unquestionable.

Wood Fire could only take a step, and when he came to her side and sat down, the Wind King knocked him down and pounced on him......

......

The saltpeter mine of Jiancao had already been mined, and when he returned to the tribe, the potassium nitrate had been made, and the sulfur powder and charcoal powder were also ready, and he began a secret experiment in the cave of Stone Mountain.

Four parts of sulfur, six parts of potassium nitrate, and nine parts of charcoal powder were fully fused, and the effect was very good.

Such bronze thunder fires, he made fifty of them, divided into three types, the fist-sized palm thunder, there are thirty, the head-sized overlord thunder, there are fifteen, and the three-foot square thunder, there are only five.

Different amounts of gunpowder, shell requirements are also different, not the harder the better, too brittle is also not good, but should be just right, when the flame is fully released, just able to crack, the power is the best.

The shell is made of bronze, the small thunder fire is crude bronze, the overlord thunder is fine bronze, the thunder is high-quality bronze, and the lead is made of silk rope, which is soaked in the alcohol purified by the spirits, and the burning speed is very fast.

The Wood Fire secretly transported the bronze thunder fire out of the stone mountain and took it to the barren mountain far away from the tribe, and placed it with solid marble around it, lit it on the spot and released it, tested their power, and found that the effect was quite good.
