It was ten o'clock in the evening, and the underworld was still fiddling with the pile of broken copper and iron in the cave.

The underworld was engrossed in the battle and didn't notice Wu Dongfang's arrival, Wu Dongfang coughed before he turned around, "Did you find my sister?"

"Not yet," Wu Dongfang stepped into the cave, "I originally lived on the border of the Turkish tribe, I came back some time ago, I just left and she arrived, we didn't make an appointment in advance, I missed it, but someone saw her, she wore a heavenly dress that could fly, and the prince and the rice bucket were with her, it was very safe." ”

"We still have to find her as soon as possible. "Mortal War walked over to Wu Dongfang.

"I already know where she might go, I'll be able to find her soon, you pack up, I'm here to pick you up this time to take you to the water tribe. Wu Dongfang said.

"What are you doing in the Aquarium?" said Stygian frowned in confusion.

"The last time I left, I told you to find you some special metal, and I found it, at the Aqua Border. Wu Dongfang said.

"What kind of metal?" Stygian Zhan picked up the jug and wanted to pour water for Wu Dongfang, but after picking up the jug, he found that the jug was empty.

"Don't be busy, I'm not thirsty," Wu Dongfang waved his hand, "Father-in-law and Styx must have told you about my origins, those metals belong to the era I lived in, and they are much better than the current metals." ”

"How did things from the era you lived in end up here?" asked Styx, puzzled.

"I'll be able to answer your question when I figure out why I'm here. Wu Dongfang said with a smile. It is the greatest support for us, thank you!

"What do you mean by metal?" asked Stygian.

"It's a machine that can fly, it's sophisticated. Wu Dongfang said.

"Let's go, let's go now. The underworld rubbed his hands excitedly.

"Don't clean up?" Wu Dongfang pointed to the rough parts in the hole.

"No, it's all here. Stygian pointed to his head.

Wu Dongfang nodded, raised his hand to condense a copper cake, and took the underworld battle into the air and headed north.

The underworld is also a person with aura cultivation, but after taking off, he has been shivering, which is naturally not cold shivering, but too excited, people who like to study meet objects worthy of study, just like a pervert who has discovered a beautiful woman, and a drunkard smells good wine.

In the early hours of the morning, Wu Dongfang arrived at the border of Liangzhou, and Wu Dongfang made a short stop from one of the cities to purchase a large amount of food and daily necessities. Due to the long distance, I returned to the village where Xunhai and Niu Niu were located at noon the next day.

Hurriedly greeted Xunhai, Shen Zhan couldn't wait to inspect the plane, Wu Dongfang had already made some introductions to him on the way here, but he was still stunned to see this behemoth with his own eyes.

Wu Dongfang didn't know much about the structure of the plane, and he explained how much he knew to the underworld, fuel was the focus of his explanation, this thing was flammable and explosive, and it would be very dangerous if it was not handled properly.

Styx has a talent for conducting scientific research, but he still can't figure out how this thing works, Wu Dongfang wanted to bring him and leave immediately, but Stygian didn't let him go, and stayed for seven or eight days before agreeing to let him go, this is not because Stygian Zhan figured out the plane, but because Stygian knew that what he knew had already been said, and it was useless to keep him any longer.

"How long will it take to create a golden-armored giant?" Wu Dongfang asked.

"Like the previous golden armor giant, you can build it in a month, but I don't want to make that kind of crude anymore, I want to make something powerful and able to fly. "Styx looked at one of the plane's engines.

"How long is the shortest?" Wu Dongfang asked again, people who are engaged in technology have quirks, they like to pursue perfection, this thing is very complicated, and if you want to make it very perfect, I am afraid that it will not be possible to do it in a few decades, and at that time the daylily will be cold.

"If you want to make a giant that I and the Stygian Moon can control, one year is almost enough, but if you want to make something that ordinary people can control, it will take at least three years, at least. The Underworld War accentuated his tone.

"Okay, you can do it slowly. Wu Dongfang nodded, the wizards of the Jin clan can control the metal, and if the Underworld and the Dark Moon control the Golden Armor Giant, they need to double as an engine and use their aura to power the Golden Armor Giant. If you replace it with someone who can't control the metal, you have to build an engine for the Golden Armor Giant, and the engine is not very accurate, it should be said that it is a power plant similar to the working principle of the Wooden Ox Flowing Horse.

"How many do you make?" asked Stydo.

"How many can you make?" Wu Dongfang asked rhetorically.

"Three, one of them and I control one, and the remaining one is controlled by ordinary people. Stygian said.

"Isn't it a pity to make only three of so many metals?" Wu Dongfang asked.

"This cylinder is broken, and even if it can be repaired with Reiki, it will reduce its hardness. "The underworld pounded on one of the engines that broke the wings.

"Okay, I'll leave it to you. Wu Dongfang said.

Stygian nodded.

"Then I'm leaving, I have to help the water tribe defend against the earth tribe. Wu Dongfang said.

Stygian nodded again.

"You're busy, I'm leaving. Wu Dongfang said goodbye to the underworld.

This time, the underworld didn't even nod his head.

Wu Dongfang shrugged his shoulders, turned around and went out, and Xunhai and Niu Niu, who were waiting outside the door, greeted him.

"Leave him alone, just prepare food and drink for him, and let him do his own work. Wu Dongfang said to Xunhai.

"Good. Xun Hai nodded in agreement, and the Underworld regarded this iron bird as a treasure, and did not let him get close to Niu Niu at all.

"I'll go see Xuanwu Heavenly Master right away, and if there's an accident here, you can call me back immediately. Wu Dongfang said.

"Take care. Xunhai said.

Wu Dongfang nodded, took out the last pomegranate from the Qiankun bag and handed it to Niu Niu, touched his head, lifted his breath and swept towards the northeast.

This is the end of the matter, and the next thing to do is to help the water tribe defend against the soil tribe.

The territory of the Shui Clan is very large, covering thousands of miles, and in fact, the territory of the other three tribes is also very large, but the territory of the Wood Tribe, the Fire Tribe, contains islands along the coast, and the territory of the Jin Tribe, which contains a large area of uninhabited mountainous areas to the west of the Jin Clan.

There are eight tribes of the water tribe, living in a relatively scattered area, the capital of the water tribe is located in the extreme north of the snow field, far away from the hustle and bustle, Wu Dongfang did not go to the snow capital city, but went to the border of the water tribe and the Tu tribe, at this time the Xuanwu Heavenly Master could not stay in the old nest, he must be on the front line of the border to command.

Five hundred miles to the east, there was a very large city, the city was full of people, there were many tents outside the city, and a large number of cattle and sheep were raised in captivity around the city.

The water tribe gathered the clansmen of the village around the city, in addition to centralized protection, there should be another reason, that is, to free up the wizards stationed in the village to rush to the front line to fight.

At this time, the territory of the water tribe is not as endless grassland as in modern times, there are still a lot of trees, with the cover of trees, Wu Dongfang bypassed this city, and flew quickly along a path leading to the southeast, after sweeping out hundreds of miles, a large number of cattle and sheep appeared on the road, and the cattle and sheep were driven by soldiers on horseback, which showed that these cattle and sheep were sent to the front line as supplies.

After traveling more than 500 miles, in the evening, Wu Dongfang found the camp of the water tribe army, the camp is located on the north bank of a river flowing from west to east, stretching for nearly 100 miles from east to west, and the places near the water's edge are all igloos, there are more than 50 places. A little farther away is a large number of cowhide tents, and there are many war horses outside the tents, indicating that the tents are inhabited by cavalry, whether it is an igloo or a tent, the location is very scattered.

Although only separated by a river, the situation on the south bank of the river is very different from the situation on the north bank of the river, and the north bank where the aquarium is stationed is warmer, and there are already young green grass buds on the ground. On the south bank of the river, however, there is a land of ice and snow, and there are many earthen huts at the foot of a hill twenty miles away from the river, far more than the igloos and tents on the north bank.

At this time, the light of bonfires came out from both camps, and it was not difficult to see through the number of bonfires that the number of people on the Tu side was far more than that of the Shui tribe.

After a short period of deliberation, Wu Dongfang fell to the periphery of the camp on the side of the Water Tribe, and walked towards the Water Tribe's camp, when he was still two or three miles away from the Water Tribe's camp, an Shui Tribe's wizard found him, "Who is coming?"

"Friends. Wu Dongfang stopped.

"Tell your name and explain your intentions. The aqua wizard shouted.

"Wu Dongfang of the Jin clan is here to discuss with the Xuanwu Heavenly Master. Wu Dongfang said.

When the other party heard this, a look of surprise appeared on his face, and after a moment he came to his senses and turned and ran towards the largest igloo on the riverbank.

Wu Dongfang waited in place, and after a few minutes, the water tribe wizard returned and beckoned to him, "The Holy Witch let you go." ”

Wu Dongfang hesitated for a moment and walked south, he thought that the Xuanwu Heavenly Master would come out, but the other party did not come out.

At the same time as he walked towards the igloo, the purple-robed celestial masters in the surrounding igloos began to gather towards the largest igloo, and when Wu Dongfang came to the igloo, there were already two columns of aquatic celestial masters gathered in the room, more than a dozen people sat on the left and right sides, and a young woman sat on the main seat in the north, wearing a water saint robe, and the front chest was embroidered with a Xuanwu pattern.

This person was between twenty-six and seventeen years old, did not wear a mask, melon seed face, moth eyebrows, phoenix eyes, and a string of purple beads hung around his neck, these beads were all purple Neidan, when there were more than twenty pieces, this woman was significantly different from the woman he had seen since he came to the Xia Dynasty, her hair was cut very short, the back to the earlobe, the front to the nose, sitting obliquely on the main seat, the right leg stepped on the edge of the seat, the hair on the forehead covered the right eye, and the left eye looked directly at him, with heavy vigilance and strong hostility.

At the first glance of the Xuanwu Heavenly Master, Wu Dongfang felt that the other party was not like a Xuanwu Heavenly Master, but more like a female bandit leader, and a bandit leader.

"Are you Wu Dongfang?" asked the Xuanwu Heavenly Master with his hair crooked.

"Are you looking for frost?" Wu Dongfang stopped in front of the door and did not enter the door.

"Yes, it's me, what are you doing here?" asked Xunshuang.

"Thank you for the water tribe's intention to go to the Jin tribe to watch the ceremony. Wu Dongfang said.

"That was my master's idea, and it had nothing to do with me. "Frost twitched his nose, and the meaning of provocation and contempt was very obvious.

Wu Dongfang nodded, walked around the igloo and walked north.

"Holy Witch, this is not appropriate, he is clearly here to help us. "The voice of an elderly man came from the house.

"If you really have the ability, you won't become a lost dog, and if you hurt the Jin family, you want to climb the flames of the water tribe, so shameless. "The sound of frost hunting.

Wu Dongfang smiled, the reason why he didn't help the Shui Tribe in secret but came to meet first, what he was afraid of was that his efforts were thankless, and sure enough, the Shui Tribe didn't look up to him, he was very glad that he didn't do anything for the Shui Clan, otherwise it would be a fake hot face and a cool butt.

After taking a few steps, Wu Dongfang lifted his breath and swept towards the southwest, without helping to pull it down, he went to do what he had to do......
