"Looking at this point, five advanced crystals are needed to activate it. It seems that the power of this giant cannon is far above the Divine Craft Cannon." Shen Luo's eyes fell on the circular groove at the tail end of the golden cannon, and he was delighted in his eyes.

He had more than a dozen high-level celestial crystals in his hand, which was enough to activate. Unfortunately, there was a forbidden God in the gray tower, so he could not use this giant cannon, otherwise Che Qingtian would have tasted the power.

Chen Luo sighed regretfully and put away the golden cannon.

The situation is urgent now, and he has no time to check the other chariots one by one, and immediately activates Xiaoyao Mirror to put away all the chariots and weapons in the hall.

Che Qingtian might come here sooner or later, but he didn't want to leave this batch of precious Yanjia to the other party.

The hall suddenly became empty, but on the innermost stone platform was placed a black iron box, emitting a faint black light, blocking Xiaoyao Mirror's collection.

"Hey, what is this box?"

Chen Luo was a little surprised and walked over to try to pick up the box, but the box seemed to be cast on a stone platform, which was also connected to the ground and could not be held at all...

He said intimately, took two steps back, and used the Chunyang Sword to slash it on it.

A "boom" sound of gold and stone fighting exploded, the sword light burst out, and the iron box fired everywhere, and it was safe and sound.

Chen Luo was about to possess her and take a closer look, the black light on the iron box suddenly fluctuated, quickly condensed into a book-like light curtain, flashing gently, as if waiting for something.

"Secret key prohibition?" Chen Luo murmured to himself when he saw this.

He had heard from Huo Lingzi that this kind of ban is usually used to protect secret rooms or treasures. The correct secret key is required to be written to open it. The secret key can be spells, words or pictures. Forced opening will only cause the ban to explode and destroy the treasures in the ban guarding.

Chen Luo thought about it for a while, golden light came out of his fingers, and he wrote the word "Yan" on the book light curtain, but it disappeared quickly, and neither the light curtain nor the iron box responded at all. Obviously, the key was wrong.

He thought about it and wrote the three words "Tianyan Palace" on the light curtain, but it was still wrong.

Chen Luo frowned and entered all possible keys, but still had no reaction.

"It seems that the owner of this iron box has set a special key. I am just a newcomer, but I am afraid I can't open it, so I'd better forget it." He was not greedy either, and turned around and was about to leave when a thought suddenly appeared in his mind.

"Maybe..." He turned around and painted a complex pattern on the light curtain of the book, which was the logo pattern at the end of the map scroll.

The pattern had just been painted and engraved, and the book light curtain suddenly fluctuated violently, and then it flashed and retracted back to the black iron box. The other black lights around the iron box were also restrained.

The lid made a "click" sound and opened automatically.

Chen Luo suppressed the excitement in his heart, looked into the box, and raised his eyebrows.

There is a half-foot-long black iron rod in the box, with many patterns and some bulges on it, which looks like another key.

"The key? Where is it to be opened?" Shen Luo took out the object.

At this moment, a blue wall next to the stone table suddenly shaking, and countless blue-gray debris fell off. After a few breaths, a closed bronze door appeared on the wall, which was twenty or thirty feet high, and looked very spectacular.

Shen Luo's vision fell in the middle of the gate, where there was a round bulge the size of a pot lid. He waved his hand and the round bulge lid slid toward the side, revealing a small black hole.

He looked at the iron key in his hand, understood a little, and inserted it in, tightly fitting, just right.

"It's really here." Shen Luo was happy and twisted his fingers.

The sound of "crack" mechanical stents were heard from the bronze gate. It stopped after a few breaths, and the thick door slowly opened.

Chen Luo looked shocked. Behind the bronze gate was a taller giant hall, hundreds of feet tall. A huge armored giant standing inside, like a mountain peak, with its head basically level with the top of the giant hall.

The entire body of the Armored Giant was golden, with strange silver-white patterns engraved on his chest and face. The two eyes as big as copper bells flashed with terrifying purple light. The thick hands were holding a giant fiery red axe and the other holding a giant black hammer. The overall look was like a natural evil spirit, and the whole body exuded endless majesty and solemnity, which was daunting.

"What a terrible man in Yanjia!" Chen Luo took a breath.

I don't know what kind of spiritual pattern the face of this giant armor is, it can release an extremely strong murderous intent out of thin air, making people feel frightened when they see it. The purple light of the giant's eyes seems to contain two balls of thunder and lightning storms, and the giant axe and hammer give people a terrible power that can destroy the world.

Among the armor that Chen Luo had seen, only the sky-raising weapon in Tianji City was better than the one in front of him.

"When it comes to the weapon of the sky, this object is indeed somewhat similar to the weapon of the sky of the sky of the sky in the city of Tianji." He looked at the golden armor twice, and a thought suddenly appeared in his mind.

At this moment, a white light suddenly flashed across his body, and the elder token of the nameless elder flew out automatically, and inserted it into the chest of the giant armor with a "click" sound, and penetrated it into it.

There was a golden part that raised a little outward, forming a door with a secret door.

Chen Luo was stunned by the situation in front of him, but soon returned to calm. He jumped to the chest of the armored giant and grabbed the secret door and pulled it.

With a "click", the secret door suddenly opened, revealing a space of about a meter in size. There were only jade bis like a mirror around it. A golden chair was placed in the center, with colorful runes engraved on it, connected to the jade bis around it, looking very mysterious.

"Is this the control place of this armor?" He said intimately, looked inside for a while, and then walked in.

As soon as he entered this place, a look of surprise immediately appeared on the sinking surface.

Because when he arrived here, the forbidden Gods everywhere in the gray tower disappeared, and his spiritual consciousness could freely extend outside his body.

Since entering the gray tower building, his spiritual consciousness has been tightly imprisoned in his body and cannot spread out at all. It seems that a layer of clothes is tightly covered with his body, which is very uncomfortable. This imprisonment has disappeared now, and he has unconsciously activated his spiritual consciousness to spread out, mixed with soul crystal silks, touching the large golden chair and the walls on all sides.

A dazzling golden light suddenly burst out from the golden chair, emitting a suction force. It was sucked into the chair without any contact, and it was unable to move.

The jade bi above it suddenly cracked, and a golden ball fell down, floating in front of the golden chair, and the ball was covered with countless mysterious slant patterns.

Shen Luo was startled and immediately sacrificed a thousand gold cups to protect his body. He soon found that there was no danger. Only then did he calm his mind a little and carefully looked at the golden ball in front of him.

"What is this?" He carefully used his spiritual sense to explore the golden ball. The patterns on the sphere suddenly lit up, and he quickly absorbed his spiritual sense.

Within one or two breaths, the sinking spiritual consciousness was swallowed up nearly half.
