The Dwarven city defense map obtained from Ironforge is divided into three parts of defense. The first part is the reconstruction of the guild wall, using the special smelting masonry of the Iron Forge, which is several times stronger than the ordinary city wall, and at the same time, its heavy iron gate has a unique way of opening, which cannot be broken through by brute force alone. The second part is the fortification, which can be built on top of the watchtower, and as long as the crystal nucleus is embedded in the turret, it can automatically turn on the defense and long-range shell fire. The third part is firearms and bombs and other traps, which are distributed in weakly defended places and key areas, which can annihilate most of the intruding enemies, and have quite strong power. Such a huge project cannot be completed in just a few days. Qing Chi and Yuan Ming Qing discussed it, took out 60% of the funds from the guild warehouse and all the income from the Qingchi auction house and the pharmacy, and hired 50 NPC workers in the city hall. As long as they are given enough food and a meager salary, these workers can work day and night.

But a thorny problem was in front of Qing Chi. Wuren Moon Cake found Qing Chi and scratched his head in embarrassment, "Vice President, this crystal nucleus is a very old thing of the dwarf clan, and there is no such thing in the dwarf engineering I studied." I can do it with the rabbits, but the power core can only be left to you. Qing Chi frowned slightly, there were only a few crystal nuclei brought back from the northern continent, but the dwarven city defense used the crystal nucleus as the core of all power, without the crystal nucleus, these city defenses were just a pile of scrap iron. That's right! Maybe you can go to the Blade Mountains and ask the Black Iron Dwarf Patriarch. Having made up his mind, Qing Chi took a few crystal nuclei and headed to the Blade Mountain Range.

When Qing Chi saw the Nice patriarch, he was drunkenly holding the wine jar and fell to the ground, snoring loudly. Qing Chi pushed him several times, but he didn't wake up, and in desperation, Qing Chi had to open a bottle of thorn wine and send it to his nose. The sleeping dwarf Ness was a spirit, and before he could open his eyes, he jerked to hold the wine bottle, and Qing Chi smiled and stretched out his hand and raised the bottle high. Ness rubbed his eyes and showed a sudden realization: "Oh! Huntress, it's you, it's been a long time. "Dear Patriarch of Ness, I have something to ask you." Qing Chi handed him the wine bottle and took out a few crystal nuclei, "Do you know this thing?" This is what I found in Ironforge. Ness stared at a red crystal nucleus in surprise, "Oh! This is something that my grandfather's grandfather's grandfather used to leave behind! It's a pity that the crystal nuclei we use now are different from this one. Even the practice has been lost. What a cute little thing! Condensed with tremendous energy. Qing Chi sighed with some disappointment, even Ness didn't know how to make this crystal nucleus. The intelligence of the facilities in the Dwarven City Defense Map is activated by this crystal nucleus. I knew that this was the case, and I should have gone to the Iron Fort in the Northern Continent again, but now at this time, the Eastern Continent is changing rapidly, and I really can't help but leave again.

Seeing Qing Chi's disappointed expression, Ness touched his beard, "Don't be discouraged, hunter." Dwarves like to be prepared and collect a lot of crystal nuclei. Just now I thought of a very old gadget, which was destroyed during the Demon War. If you can find its parts, maybe it will help you find what you're looking for. ”

Ness took a long time from under his feet and pulled out a mechanical chick covered in mud. Qing Chi looked at the chicken very speechlessly, her heart was overwhelming, she had no doubt that this mechanical chicken was stained with mud and dirt on Nice's body, after all, dwarves are the least bathing race. "It was first made by an angry goblin who used his early morning chirp to harass his neighbors. At that time, there was a race of goblins, and they made much more elaborate things than the dwarves. It's a pity that I haven't heard of them since the battle of the demons. The crystal nucleus used by the dwarves was actually first invented by the goblins. As long as you follow this chick, it will surely lead you to what you have in mind. Ness lifted the wings of the mechanical chick and embedded a red crystal nucleus, the mechanical chick tilted its neck, made a "cluck" sound in its throat, flapped its wings twice, and walked up with a twist. Ness clapped his hands happily, "Oh! I can't think it will still work, go ahead, huntress, protect this mechanical chick, maybe you can find something useful, good luck. ”

Qing Chi twitched the corners of his mouth, and a few black lines floated across his forehead. This chick is too slow to move, how many years and months do you have to follow it yourself? The mechanical chick jumped a hundred steps, and Qing Chi only took two steps to catch up. But you can't help but keep up, if it accidentally gets trampled by a mob or NPC, or suddenly disappears somewhere, it will become a big problem. Qing Chi sighed, resigned himself to following the mechanical chick, through the cave with twists and turns, and finally came out of the ground, and at this time it was already a faint light of the stars.

Just as Qing Chi was yawning and sleepy-eyed, the mechanical chick suddenly flapped its wings.

"The flight system is activated, cluck! Launch a rocket to reach the Hinterland Bend! Just when Qing Chi opened his eyes, the chick fluttered its wings and flew out, and the black mud on its body couldn't hide its tender yellow coquettishness. Just a blink of an eye, it's already a long way away. It's so perverted! Qing Chi hurriedly summoned out the dark clouds and sped in the direction where the chicks flew. At this time, the sky is gray, and if you accidentally lose it, at its speed, you will definitely never be able to find it again. Qing Chi accelerated while shaking the reins, staring at the hateful chick without blinking. Finally, after crossing the plains and swamps, Qingchi finally reached his destination, the Hinterland Bend. To Qingchi's surprise, this river bay is obviously called Jiakou River Bay. For here, Qingchi is no stranger to it. He once killed a poisonous frog here, held a white sky hostage, and opened the riverbend fortress. Unexpectedly, the mouth of the bay in the mouth of the mechanical chick made by the goblin is actually called the Hinterland bay, what is going on? The mechanical chick fell from the sky, stumbled its feet, and walked towards a large, smooth boulder on the shore of the bay. Qing Chi followed curiously. When they reached the shore, the mechanical chick stopped and kept crying, "Danger in the water!" Danger in the water! ”

Is it looking for something? Qing Chi thought about it, took out a bottle of underwater breathing medicine from his backpack, and plunged into the river. After groping for a while in the deep water near the riverbank, I finally found something hard in the mud. Qing Chi grabbed the thing, then took a deep breath and leaned out of the water and climbed ashore.

It's another mechanical hen. Compared to that chick, it is dark red in color and larger in size. And the hen was bulging under her wings, as if something had been clamped between it. Qing Chi took out a piece of parchment from under his wings. Despite the many years that have passed, the paper is still very well preserved, the parchment seems to have been soaked in some oil, the surface is covered with a layer of wax, the waterproof effect is very good, and the handwriting on it is still legible.

System: "You found a strange metal object, and after a few random rummags, a piece of parchment appeared, turning into a mechanical device that appeared to be made by a goblin. Curious, you open the parchment, what could it be? ”
