Chapter 730

The huge black bull just looked at him lazily and still walked slowly in front of him. Ulm was lucky to feel that he had been greatly insulted. Along the way, how many beasts did he kill, but this guy actually didn't hang himself. He angrily came forward and aimed at the black giant cow and swun his big bone stick, just...

"Wait a minute--that's..., don't--" The indigenous scout who bypassed the black bull monster looked back and saw that Ulm was lucky to attack the huge black bull monster and shouted anxiously, but it was too late. He immediately hid in the canopy of a big tree...

A loud sound of "ping-" actually shook a layer of sound bomb that was visible to the naked eye! However, the giant bull did not seem to have been killed. Fortunately, Ulm screamed, and the huge leg bone flew out of his hand. His hands were cracked, his arm was broken, and his body was knocked to the ground by his own anti-shock force!

The black giant cow looked back lazily at Ulm, and his eyes were full of sarcasm. Its giant hooves turn around, lowering its head, and a pair of huge horns will kill the giant man!

"Please wait a moment!" Zhang Fan immediately came forward with his teammates and lined up the battle formation. Zhang Fan shouted.

Everyone is worried that the defense of this huge black cow is so high. Urm is lucky that even the 'chilled' monster dares not carry it so hard! Even if you sacrifice your life, you will definitely be hit hard, and this black bull doesn't seem to even feel it. What kind of defense is this! Will the weapon in your hand work on it?

"Wow--" The black cow roared, and its voice was very loud, as if an iron bell was ringing. Why do you humans attack me for no reason?! Don't you allow me to fight back?" The black bull spit out people's words, obviously open their intelligence, and is a legendary monster.

"This is our fault. I met too many monsters along the way and always hurt people for no reason. We saw that you were huge and thought it was also a fierce monster, so..." Zhang Fan quickly defended.

"Mou - don't talk nonsense, it's okay if you want this guy's life! I see that you have so many weapons. Give me some and I'll let you go!" The black bull roared.

Zhang Fan and Aken are very strange. What's the use of this black cow without hands and feet? What's more, its body is so strong that the giant horns are comparable to the most powerful weapons. Does it still need weapons and armor?

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

The black cow's eyes really stared at the King Kong pestle in Zhang Fan's hand and swallowed his saliva. "Of course it's eating--" The eyes seemed that Ulm was lucky to look at a piece of barbecue.

The eyes of the black bull made Zhang Fan's heart flustered. How many hardships have he experienced when he raised his King Kong pestle to this level! Even if you don't talk about the value of this prop, it is difficult to give up emotionally.

"Eat!" Zhang Fan and Aken looked at each other in consterance. Did he meet a monster that made a living by swallowing props? Impossible. Even if there is such a monster, it should produce more abundant props in future generations. In this era, there are many alchemy materials and not many props refined. Besides, looking at this guy's size, it's not one or two props that can be fed!

"Don't talk nonsense! Of course, eat. Otherwise, what else? I'm tired of the hard stones in this mountain. They are all dry and tasteless. Looking at the weapons in your hands, they seem to be delicious. Black Bull is a little impatient.

"Eat hard stones? Your digestive system is so good..." Zhang Fan Aken doesn't seem to have heard of such an ancient monster.

Was hesitating, the black cow opened its mouth and bit Ulm...

"Ah--" Everyone screamed, and Ulm was so scared that he curled up.

But this black cow did not bite Ulm, but swallowed a dark red stone at his feet and ate it as sweet as chewing a handful of fried hard broad beans.

Aken was panicked and sent a message to remind Green Wing: "If there is a fight, Zhang Fan will attract its attention in front of it, and we will run to its back to insert its asshole!" The defense there will not be too strong!"

As he spoke, the black cow suddenly sounded in his stomach, his eyes were dull, and then his hind legs were a little bit, ** loosened, "jingle!" There was a sound and I actually took a shit. However, in addition to a lot of gravel, this bubble of poop is actually some sharp steel!

Green Wing looked contemptuously at Aken, "It seems that its defense is also very strong..."

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

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

Aken 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, while Zhang Fan's diamond pestle was several metal alloys. No wonder it could attract it. And the dark red stone at the foot of Ulmsin must be high-purity iron ore. Maybe this mountain is also an iron mine, so you can meet such a monster!

At this time, the book demon took a step forward and said to this 'iron': "Our weapons are just a little metal, I'm afraid it's not enough for you to stuff your teeth. You can see how good it is. We can find metal-rich stones for you to make a meal!"

"Mow--" The big black cow shouted, "Can you help me find it? I feed on iron, and it's effortless to find this kind of stone, but the iron stones in this area are about to be eaten up by me. What can you do?!"

The book demon laughed and said, "It is impossible for you to eat it all. You can probably smell the rich iron stones under the mountains, but these iron stones are buried too deep for you to enjoy. I have a way for you to eat this rich ore!"

"Is this true?" A pair of big volleyball bulls stared round and went straight to the book demon. In its eyes, this strange old man is a knowledgeable person, but he believes it 80%. The ore with a high metal content under the mountain stone has long made it difficult. However, the mountain stone is hard. It is difficult to hit with a huge horn and difficult to mine.

So this guy can only find some iron stones on the surface to eat. The cave where this guy is located is an iron ore mountain wall that was hit by it with a huge horn, but it ate too much and collapsed. Fortunately, it has strong defense and is not injured, but it is almost suffocated. This time, I came out to find a new place to mine iron and stone.

"No lie!" The book demon nodded and smiled.

"If it's true, then I will thank you very much!" The iron said loudly.

When Zhang Fan saw that the book demon was so full of money, he didn't know what magic he had to mine iron ore. Instead, Aken thought of it and asked the 'iron', "How will you thank us?"

The cow monster was also simple and said, "There are several good things in my original cave, but the mountain wall collapsed. If you have a way to mine iron stones for me to eat, you must be able to dig out those treasures. Just take it as my thank you."

Aken's heart had been itchy for a long time when he heard the word baby. He turned around and shouted, "Youda! Your life is coming!"

The book demon smiled and nodded. Naturally, he knew that the Goblin was an a mine-opener, but this little guy alone could not do it.

Zhang Fan also understood the intention of the book demon and said to him, "It is very difficult to smelt bronze in this era. How can we smelt iron? Moreover, copper refining is relatively easy, and ironmaking requires a high furnace temperature, which is difficult.

"It's man-made. I have the ancient furnace styles of smelting iron ore, which are all primitive and easier 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 just impart this civilized skill to these Chinese human beings in advance. What's the difficulty? The book demon said with a long beard.

Yoda jumped over and said, "It's really not difficult. We Goblins also have the ability to mine and smelt in a simple way, as long as the human beings here are not lazy. Besides, they have mastered the technology of smelting bronze and should learn it quickly!"

Aken also nodded, "And this 'iron' can also help a lot. You see, its stomach is a natural refiner." Akan picked up a few sharp fine steel from the pile of gravel excrement. "These are all fine steels refined by this guy's stomach. A little processing can make the best iron tools and weapons."

Ancient woman sighed: "I didn't expect you to be able to refine this kind of gold essence. In the past, our people once picked up some gold essence in this 'iron' feces to make some excellent weapons, but this gold essence is too hard to exercise. If you have this skill to exercise gold essence, I would like to ask my Jiuli compatriots to help you mine!"

"Wo--" This 'iron' heard it clearly and shouted excitedly, "I still have a few of my relatives, so I called them to come together. This place is not far from your human race. We will escort you there!"

Zhang Fan was overjoyed. With the help of these 'iron', it would be much easier for these Chinese people to smelt iron ore. Moreover, this 'iron' defense is strong, and it will no longer be afraid of the invasion of ancient monsters in the future. Later Chu land is also the first iron-making land 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. With the intervention of their own team, they have entered the Iron Age thousands of years ahead of schedule!

This 'Yi Tie' soon summoned several companions, and there was a roar of ox. These 'Yi Tie' were also extremely excited. They all took the initiative to open the way for Zhang Fan's team, carry everyone all the way over the mountains and went straight to the gathering place of the largest tribe of the Jiuli tribe!

The hometown of this ancient priestess, the gathering place of the largest tribe of the Jiuli ethnic group, turned out to be a cottage alliance. Nine tribes occupy a large mountainous area with a population of more than 100,000! This was an extraordinary scale of human gathering at that time!
