Gao Cheng followed the passage, according to the instructions of the mechanism map, and continued to open the mechanism to advance, after some dangerous places, Gao Cheng and the people behind him saw that on the side of the wall, someone had carved a line of words with a long sword or dagger, on which were written the words that the Goryeo Rakshasa had been here.

Li Shimin's spirit was shocked, and he said: "This is indeed the gate of the treasure house, the Rakshasa woman Fu Junwu once entered the Yang Gong treasure house and took a few treasures from it, there will be no mistake!"

Li Jiancheng in the back seemed to be a little impatient, and hurriedly stepped forward and pushed open the door, when he suddenly heard the sound of the organ. Dozens of specially made steel arrows shot from the dark place, and the sound of breaking through the air with a sharp roar was particularly piercing in the silent underground passage.

The rain of arrows rushed in, covering the entire space of the passage, and unless everyone turned into a piece of paper and stuck it on the wall, no matter how good they were, they couldn't dodge.

And this kind of steel long arrow is launched by a crossbow, and after Lu Miaozi's adjustment, the power is a hundred times more powerful than ordinary crossbow arrows. Ordinary masters of the rivers and lakes will die if they are trapped.

"Ah! there is a mechanism!" Li Jiancheng exclaimed.

Gao Cheng shook his head, grabbed his right hand backwards out of thin air, and with a bang, a short knife that Li Xiuning carried with him at his waist appeared in his hand, the cold light flashed, the sword qi roared, and the strong and domineering sword qi split hundreds of ways in the void, forming a sword qi light curtain.

Pengpeng, these long arrows sank deep into the walls on both sides, and after a while, the sound of the arrow rain whistling gradually disappeared, Li Jiancheng, Li Shimin, and several other Li valve masters saw the stainless steel long arrows on both sides, and subconsciously wiped a cold sweat.

If it weren't for Gao Cheng's action, at least half of them would have died.

"Let's go, there's no mechanism for the rest of it!"

Gao Cheng said lightly, and took the lead towards the passage, and at the end of the passage, there was a wall full of firing holes, and a passage appeared on the left side, leading to another space.

As they walked briskly, their eyes suddenly widened and they entered a sealed basement with vents at all four corners of the roof. On both sides, there are more than a dozen chests that should be loaded with rare treasures, and there are dozens of weapon racks on the wall, full of various weapons. But they are all just ordinary goods, and all of them are rusty and moldy, and no one wants to give them away.

"This is the Yang Gong Treasure House? The legendary Yang Gong Treasure House, which is so rich and invincible, is it just a weapon?" Li Jiancheng saw these things, and his face was indescribably disappointed, and he felt that a basin of cold water was poured on his face.

Li Xiuning frowned slightly, stepped forward and opened the box, which was full of ancient jade treasures, which seemed to be worth a lot of money, but these things were too far from the rumored treasure house.

Pang Yu, Eldest Sun Wuji, and Dou Wei glanced at each other, all showing disappointed expressions.

Li Shimin said suddenly: "Third brother, you said that the relics of the evil emperor are in the treasure house, and now the relics are nowhere to be found...... Could it be that we haven't reached the real treasure trove yet?"

Gao Cheng said: "Yes, this is just a fake treasury, the real treasure trove is still behind......

Yang Gong's treasure house is the "cross layout" in the architecture of Lu Miaozi's organs. There is a switch in the south and north walls, which is an "interlocking" mechanism, which means that both sides must be opened at the same time before the mechanism room will be opened.

If ordinary people come to the treasure house, they don't know the mystery of the mechanism, and they can only get these things in the fake library if they go through all the trouble of breaking the mechanism.

Li Jiancheng and others heard the news, and only then did they recover their mentality. At this time, they all closed their mouths, no longer suffering from gains and losses, and according to Gao Cheng's instructions, they divided the two of them to hold down the north and south organs. With a click, another passage appeared in front of everyone's eyes. On the top of this passage, the night pearl is used as a candle flame, flashing with misty brilliance.

After passing through the Heaven and Earth Lock and other mechanisms, everyone finally came to a circular stone room, with a stone table in the center of the stone room, and eight stone chairs, on which a map of the entire treasure house was drawn. It shows the relationship between the treasure house and Chang'an City.

"Yang Gong's treasure house actually leads directly to the outside of the city?"

When Li Shimin saw the map of the treasure house, a layer of cold sweat suddenly appeared all over his body, and he instantly thought that if the army came to Chang'an City, there was no need to attack the city at all, and through the passage of the treasure house, the city wall of Chang'an City would be useless.

When Li Jiancheng and Li Xiuning heard this, they also thought of this instantly, they didn't expect that their own capital would have such a big loophole. As long as it was Li Valve, everyone was scared.

"It's okay, it's okay! We already know the secret passage of Yang Gong's treasure house, as long as the secret passage is sealed, we don't have to worry about others using the treasure house to enter Chang'an City!"

Thinking of this, everyone relaxed. At this time, Li Jiancheng and Li Shimin discovered that there were four rooms in the four directions, each room was a hundred steps wide, three rooms hid weapons, and the other room hid gold, silver and jewelry.

Gao Cheng said: "There are hundreds of thousands of taels of gold stored here, as well as armor and weapons that can arm 10,000 elite soldiers, which are worth a lot of money. Big brother and second brother, you guys should take someone to transport these things out first!"

He pointed, and then turned his attention to the stone table, which he grabbed and pulled up, and the stone table rose two inches up with a soft sound. There was a sound of the wheel grinding under the round table, and it turned to the left.

The floor of the table sank down, revealing a narrow space inside, and I saw a small copper jar in it, which was the jar containing the relics of the evil emperor.

Gao Cheng took out the jar casually, and various scenes full of blood suddenly appeared in his mind, and thousands of life-seeking ghosts cried in his ears, which was very terrifying.

The demon seed in his body seemed to sense the breath of the relics, and suddenly jumped up unkemptly.

Gao Cheng immediately operated the Innate Immortal Technique and suppressed the power of the demon seed, this is not the place to absorb the essence of the relics. He brought a deerskin glove and removed the yellowish crystals from the jar.

This pale yellow crystal is the supreme treasure of the Demon Gate, the Evil Emperor Relic.

At the moment when the evil emperor's relics appeared in the air, hundreds of miles away in Luoyang City, Shi Zhixuan, Zhu Yuyan, and Wanwan, who were hidden in the city, these innate masters whose magic skills had reached a certain level, sensed that something had finally appeared in the world.

Shi Zhixuan appeared on the roof with a sigh, looking in the direction of Chang'an, his face gloomy.

"Evil Emperor Relic!"

Zhu Yuyan and Wanwan also understood, and they gathered their manpower one after another, gave up continuing to besiege Kou Zhong and Xu Ziling in Luoyang City, and rushed towards Chang'an with all the elites of the Yin Kui faction.

The news channels of other forces in Luoyang City could not be ignored, and in less than half a day, they all knew the reason why the Yin Kwai faction left so quickly.

Yang Gong's treasure house, especially the Demon Gate Supreme Treasure Evil Emperor Relic, appeared in Chang'an!

When the news came out, there was a great earthquake in the world, and a large number of demon masters went to Chang'an, as well as the concubine Xuan of Cihang Jingzhai, the four great kings of Jingnian Zen Temple, and even the master of Jingzhai Fan Qinghui and the presiding monk of Zen Monastery all went out one after another.

Compared with the relics of the evil emperor, the matter of He's bi is secondary. A Heshi Bi can't let Kou Zhong seize the world, but if the people in the Demon Gate get the relics of the Evil Emperor, then it is very likely that an Evil Emperor will appear and dominate the Demon Gate, bringing a devastating blow to the Buddha Gate and Cihang Jingzhai.
