It may be thousands of years ago or tens of thousands of years ago, these sects that were hiding deep underneath and secretly making puppets were unfortunately discovered by their opponent Sword God one day. The sect had no ability to resist, and the puppet that had been carefully researched for many years was destroyed as soon as it was activated.

After many years of that, a descendant of humans re-visited the area and found extremely precious quicksilver, perhaps the stock of materials used to make the puppets, which magnified the greed of the human beings and caused a fight here once again.

Yin Jiuchen stood in the middle of the hall, looking at these motionless and mutilated puppets, and used his own ideas to perfect the causes and consequences of the current situation.

"These puppets are almost destroyed, they don't work, let's go inside. Yin Jiuchen looked left and right, found another exit, recalled all the torches, and continued to walk.

These underground passages are arranged very carefully, and the places to be visited are also marked very clearly, Yin Jiuchen tries his best to go in the direction of the words "warehouse", "energy", "smelting", "synthesis", etc., since Miyazu Yu is here to find quicksilver, it is necessary to go to this kind of place.

As Silver Jiuchen deliberately approached the places where these precious materials were placed, mechanisms began to appear on the way to it. The power of these organs is not great, and the Spirit Law Realm can easily deal with them, Yin Jiuchen does not dislike these mechanisms, on the contrary, he likes them very much, which shows that he is approaching an important area.

Finally, after Yin Jiuchen had gone deep for an unknown amount of time, he came across an item that did not belong to this passage, a broken shoulder armor. Yin Jiuchen didn't know if this belonged to Yangcheng or the shoulder armor of the Northern Kingdom, anyway, someone had been here, and he had gone to the right place.

After the appearance of the shoulder armor, as the mechanism became more and more dangerous, Yin Jiuchen saw more and more broken items, and finally came to another open place. A smell of blood wafted into Yin Jiuchen's nose, and he was shocked, so he hurriedly picked up his amethyst eyes, extinguished the torches, and dodged to the side.

Whoosh! Whoosh!

Several arrows pierced through the air one after another shot at the place where Yin Jiuchen had just stood, half a foot deep into the floor.

Yin Jiuchen heard the humming of the bow and arrows, this was definitely not a mechanism, but a living person shooting arrows.

To deal with such a person, Yin Jiuchen didn't need to be soft, he directly raised his hand and shook it at the place where the bowstring was buzzing.

"Martial Arts: Space Burst!"

The spatial explosion did not catch anyone, but the subsequent explosion had a wide invisible range, directly blasting the hiding place of the person who sneaked up on Yin Jiuchen, exposing it to Yin Jiuchen's amethyst eyes.

The three sergeants who attacked Yin Jiuchen were judged from their uniforms, they were from Yangcheng, and the realm came to the sixth or seventh order of imperial qi.

Yin Jiuchen's figure disappeared in place, and when he reappeared, he had already turned into nine people, completely blocking the escape route of the three people, and the three of them looked desperate.

"Answer my question, and I'll let you live. Yin Jiuchen and the nine figures spoke at the same time, majestic and weird, and the three of them all regretted their intestines, and nodded like garlic.

"Why are you hiding here and sneaking up on people?"

"The captain ordered us not to let anyone in. ”

"Where did your captain go?"

"Go to the synthesis hall. ”

"Have you seen a man named Miyazuha?"

"I don't know ......," the three shook their heads.

The clue was broken, Yin Jiuchen dispersed his clone, raised his hand and waved, cutting off the three arms of the three people who drew the bow, which was regarded as punishing their sneak attack, and turned around and hurried towards the synthesis hall.

When he approached the synthesis to inquire, Yin Jiuchen vaguely heard the shouts of the human being, his eyes lit up, and he quickened his pace.

The figure of the black-haired boy rushed into a huge space, which was not as dark as the others, but shone with a bright red light, and the floor, roof, and surrounding walls were no longer pure dirt dug out of space, but were tightly stitched together by hard metal materials.

The fighting people in the synthesis hall noticed the new powerful aura, but they were already red-eyed at the moment, and they didn't care who the newcomer was.

Yin Jiuchen became the target of everyone, so there was no way to ask questions.

Yin Jiuchen's figure disappeared, and when he reappeared, he had already turned into nine people, and the irritable thunder and lightning power gathered in the sky above the hall, and the nine formations echoed each other, and countless thunderbolts slashed down.

"Martial Arts: Thunder Summons!"

The dense thunder attacked the crowd indiscriminately, and in order not to be affected, the two sides of the battle temporarily gave up the death match one by one to avoid the attack of the thunderbolt, and the two sides of the battle were forcibly separated by Yin Jiuchen.

Not only that, after the two sides were clearly separated, Yin Jiuchen stepped on the ground with one foot, and the formation was instantly formed, and the thick barrier isolated the two sides, making them unable to fight for the time being.

Both sides were immediately suppressed by Yin Jiuchen's methods.

"Let me ask you, where did the person who walked in front go?" Yin Jiuchen had no intention of revealing his purpose.

The people on both sides hesitated for a moment, and both pointed in one direction.

"That's fine, you can keep fighting. Yin Jiuchen kicked open the barrier and went to the place pointed by both sides, and soon disappeared.

"Who's that guy?"

"I don't know, I haven't seen it, he didn't help anywhere. ”

"Could it be someone from another force?"

Yin Jiuchen's agitation made the two sides who killed the red eye just now calm down a lot, thinking back to the appearance of walking on the edge of danger before, they couldn't muster up the courage to fight again, and they all retreated to their own side, glaring at each other.

Yin Jiuchen, who was moving forward, found that the passage had changed very much, it was all made of metal, and he didn't know how much ore it spent, all of which was getting farther and farther away from his previous conjecture, this was not a sect, nor was it a city, what was it?

When he walked further, Yin Jiuchen heard the sound of liquid flowing, which didn't sound like water, but some kind of viscous and bulky liquid, and Yin Jiuchen couldn't help but think of the thing that the Northern Kingdom and Yangcheng were fighting for: quicksilver.

These voices all penetrated deep into the depths of the passage barriers, and Yin Jiuchen had no way to find out, it was too laborious to break through these heavy passages, and it would consume a lot of true spirits.

Just when Yin Jiuchen listened to the voice, thinking about all these strange scenes, and walked around a corner, a huge crisis dared to suddenly come from the side, Yin Jiuchen was taken aback, and only had time to launch the "illusory".

A big sword pierced through Yin Jiuchen's body from top to bottom, and smashed the solid metal ground into a deep pit with great force, although Yin Jiuchen tried his best to avoid the physical damage, but the impact of the follow-up aura was too strong, and it acted on his body on another level through the "illusory", making him spit blood from his mouth.

"Oh? I survived, interesting. A deep male voice rang out.
