The huge black bull just glanced at him lazily, and then still walked in front of him unhurriedly. Ulm Xing felt that he had been greatly insulted, how many beasts he had killed along the way, and this guy actually didn't hang himself. He roared angrily and stepped forward, aimed at the black bull and picked up his big bone stick, which was a ......

"Wait a minute——, that's ......, don't-" The native scout who had bypassed the black bull monster shouted when he saw that Ulm was about to attack the giant black bull monster, but it was too late. He immediately took refuge in the canopy of a large tree......

There was a loud bang, and a layer of sonic boom visible to the naked eye was vibrate! However, the giant bull did not seem to be killed, but Ulm Xing screamed miserably, and the giant leg bone flew out of his hand, and his hands were cracked, his arm was broken, and his body was knocked to the ground by his own shocking force!

The black bull glanced back lazily at Ulmuxing, his eyes full of mockery. Its huge hooves turned, and as soon as it lowered its head, a pair of huge horns were about to kill the giant man!

"Wait a minute!" Zhang Fan and his teammates immediately stepped forward and lined up in battle formation, Zhang Fan shouted.

Everyone was worried in their hearts, the defense of this huge black bull was so high, Ulm was fortunate to blow this blow, even the 'chiseled tooth' troll would not dare to carry it so hard! Even if you sacrifice your life to bear it, it will definitely be hit hard, and this black bull doesn't even seem to feel it, what kind of defense is this! Will the weapon in your hand have an effect on it?

"Moo-" The black bull roared, and his voice was very loud, like an iron bell ringing. "You humans, why are you attacking me for no reason?! Don't you want me to fight back? "The black bull speaks, obviously enlightened, and is a legendary monster.

"It's our fault. There are too many monsters along the way, and they will hurt people for no reason. When we saw that you were huge, we thought you were also a fierce monster, so we ......" Zhang Fan hurriedly defended.

"Moo - no need to talk nonsense, if you want this guy's life, you can do it! I see that you have so many weapons, give me some, and let you go!" The black bull roared.

Zhang Fan Aken is very strange, seeing that this black bull has no hands and feet, what's the use of asking for weapons? Besides, its body is so strong, and the pair of giant horns is comparable to the most powerful weapon, can it still use weapons and armor?

"You...... What kind of weapons do you want? What's the use? "Akon is worried that this guy has taken a fancy to himself and his teammates' dark gold props, so it is better to fight.

The black bull's eyes really fixed on the vajra in Zhang Fan's hand, and he swallowed his saliva, "Of course it's eating-" The look seemed to be Ulm Xing looking at a piece of barbecue.

The eyes of the black bull made Zhang Fan's heart furious, and how many tribulations his vajra had gone through when he had been promoted to this level! Even if you don't talk about the value of this prop, it's hard to give up even emotionally.

"Eat!" Zhang Fan Akon looked at each other, did he encounter a monster that made a living by devouring props? It's impossible, even if there is such a monster, it should be in the future when the props are more abundant. In this era, there are a lot of alchemy materials, and there are not many props to be refined. Besides, looking at the size of this guy, it's not something that can be fed with two props!

"Don't talk nonsense! Eating, of course. Otherwise, what are you doing? I'm tired of eating the hard rocks in this mountain, they're all dry and tasteless. Look at the weapons in your hands, they seem to be delicious. "Black Bull was a little impatient.

"Feeding on hard rocks? Your digestive system is too good......" Zhang Fan Akon didn't seem to have heard of this ancient monster.

As he hesitated, the black bull opened its mouth and bit Ulmuko......

"Ahh

But the black bull didn't bite Ulmuxing, but swallowed a dark red stone at his feet, and ate it like chewing a handful of fried dry and hard broad beans.

Akon looked panicked, and sent a message to Green Wing: "If there is a fight, Zhang Fan will attract its attention in front, and we will run to its back and insert its!" Its defenses there won't be too strong! ”

As he was talking, the black cow suddenly roared in his abdomen, his eyes were dull, and then his hind legs were parted, and the chrysanthemum was released, "Jingle bell!" There was a loud noise, and there was a bubble of. However, in addition to a lot of gravel, this bubble of poop also turned out to be some sharp and sharp steel!

Greenwing gave Akon a disdainful look, "Looks like it's defenses strong there......"

"Iron!" The ancient priestess, Zhang Fan, and the book demon all exclaimed. This bull demon turned out to be the legendary monster that feeds on iron, 'Iron Iron'! No wonder the defense is so high, and it can also pull out manure as sharp as steel!

"I thought it was the Bull Demon King!" Xuanyuan Xing wiped his sweat and muttered.

Akon heard about this monster's hobby, and knew the reason why this guy likes weapons, it turned out that he wanted to eat pure iron, and Zhang Fan's vajra was several metal alloys, no wonder it could attract it. And the dark red stone at Ulmsin's feet must be a high-purity iron ore. Maybe this mountain is also an ironstone mine, so you can encounter such monsters!

At this time, the book demon stepped forward and said to this 'iron': "Our weapons are so metallic, I'm afraid it's not enough for you to stuff your teeth." You see, we can find you a metal-rich stone for you to have a meal for! ”

"Moo-" the big black bull chirped loudly, "you help me find it?" I feed on iron, and it's easy to find this kind of stone, but I'm almost running out of iron and stone in this area, what can you do?! ”

The book demon smiled: "It's impossible to be eaten by you, you can probably smell the rich iron stones under this mountain range, but these iron stones are buried too deep for you to enjoy." I've got a way for you to eat this abundant ore! ”

"Is that true?" A pair of volleyball-sized bull's eyes widened and walked straight to the book demon. In its eyes, this strange old man with a big head looked like a knowledgeable person, and it believed eighty percent. The ore with a high metal content under the mountain stone has long made it itchy and unbearable, but this mountain stone is hard, and it is difficult to mine it with a huge horn.

This guy can only find some iron and stone on the surface to feed. The cave where this guy is located is an iron ore mountain wall that it knocked out with a giant horn top, but it has to eat too much, and the stone wall collapses. Fortunately, it had strong defenses and was not injured, but it almost suffocated to death. This time, I came out to find a new place to mine iron and stone.

"No lie!" The bookdemon nodded and smiled.

"If it's true, then I'll thank you very much!" 'Iron Iron' said loudly.

Zhang Fan saw that the book demon was so big-packed, and he didn't know what magic he had to mine iron ore. Instead, Akon thought of it and stepped forward to ask the 'Iron Iron', "How will you thank us?" ”

The bull monster was also honest, and said: "There are a few good things in my original cave, but the mountain wall has collapsed, if you have a way to mine iron and stone for me to eat, I must be able to dig out those treasures." Think of it as a thank you gift from me. ”

As soon as Akon heard the word baby, he was already itching, and he turned around and shouted: "Yoda! You're alive! ”

The book demon smiled and nodded, he naturally knew that this goblin was an expert in mining, but this little guy alone couldn't do it.

Zhang Fan also understood the intention of the book demon, and said to him: "Smelting bronze in this era is a very laborious thing, how can you smelt iron?" Moreover, copper smelting is relatively easy, and iron smelting requires a high furnace temperature, which is difficult. ”

"It's man-made, I have here the style of ancient iron ore smelting stoves, which are all primitive and relatively easy to build. And they already have the ability to smelt copper, and it is only a matter of time before they learn to smelt iron. We are just passing on this civilization skill to these Chinese humans in advance, so what's the difficulty? The book demon said with his long beard stroked.

Yoda jumped over, "It's really not difficult, we goblins also have the ability to mine and smelt in a rudimentary way, as long as the humans here are not lazy." Besides, they have already mastered the jishu of smelting bronze, so they should learn it quickly! ”

Akon also nodded, "And this 'Iron Iron' can also be of great help, you see that its stomach is a natural refiner." Akon picked up a few sharp strands of steel from the pile of gravel and dung, "These are all haode steel refined by this guy's stomach, and a little processing can make the most haode iron tools and weapons." ”

The ancient woman sighed: "I can't imagine that you can still smelt this kind of gold essence, in the past, our people used to pick up some gold essence from this 'iron' dung to make some excellent weapons, but this gold essence is too hard to exercise. If you have the skill to exercise the golden essence, I am willing to let the Jiuli compatriots help you mine! ”

"Moo-" The 'Iron Iron' heard it clearly, and let out a long cry of excitement, "I still have a few of my kindred, so I'll call them to come together." This place is not far from your human race, and we will escort you there! ”

Zhang Fan was overjoyed, with the help of these 'iron', it was much easier for these Chinese people to smelt iron ore. Moreover, this 'Iron Iron' has strong defense, and it will no longer be afraid of the invasion of ancient monsters in the future. In later generations, Chu was also the first iron-making place in China, with rich iron ore resources, which is also the reason why this kind of 'iron' can survive. Now the Chinese talents here have just transitioned from the Stone Age to the Bronze Age, and with the intervention of their own team, they have entered the Iron Age thousands of years ahead of schedule!

This 'Iron Iron' quickly summoned a few companions, and there was a roar of the bull, and these 'Iron Irons' were also very excited, and they all took the initiative to open the way for Zhang Fan's team, carrying everyone all the way over the mountains and mountains, and went straight to the gathering place of the largest tribe of the Jiuli Clan!

The hometown of this ancient priestess, the gathering place of the largest tribe of the Jiuli tribe, turned out to be a copycat alliance, and the nine tribes occupied a large mountainous area, with a population of more than 100,000! This was an extraordinary human gathering at the time!
