Entering this corridor, it actually gave people a very spacious feeling. The corridor did not go directly down, but went straight forward. There were thick stone walls all around. The thickness was more than one meter. Even with Han Yu's mental strength, it was difficult to directly pass through such a thick barrier.

After walking about ten meters, three doors appeared in front of us. On each door, there were ten number buttons from zero to nine, and a keyhole.

If Han Yu had not followed Li Chong here with his spiritual clone, he would not be able to resolve this trap no matter how smart he was.

This is also the second level of protection here.

Just as they arrived in front of the three doors, suddenly, accompanied by a crackling sound, small holes appeared in the surrounding walls. One by one, cold metal soul guide ray tubes protruded from inside, completely blocking all possible spaces for dodging.

Qiu'er's keen perception detected something strange, and her soul power subconsciously surged, but she was stopped by Han Yu's low shout, "Don't move!"

The low shout came suddenly, like a thunderclap, causing Qiu'er's originally prepared movement to stop abruptly.

She turned to look at Han Yu in confusion, with a hint of puzzlement and inquiry in her clear eyes.

Perhaps it was because of her deep trust in Han Yu, or perhaps she was shocked by his serious expression, Qiu'er's tense body finally relaxed. She cast a puzzled look at Han Yu, waiting for his explanation.

Han Yu's face was calm, and his deep eyes swept over the surrounding mechanisms. He slowly said: "These mechanisms are exquisitely designed and linked together. If they are triggered at will, it is likely to trigger a chain reaction and cause unnecessary trouble."

He paused, then explained, "As long as you find the right door and enter the correct password, these mechanisms will not attack."

As he spoke, he turned his gaze to a metal door on the left, pointed at it and said to Qiu'er: "Qiu'er, the door on the left, the password is three, seven, six, four, five, one, six, nine..."

As Han Yu finished speaking, a series of sixteen numbers clearly entered Qiu'er's ears. Without any hesitation, she walked to the left door, quickly glanced at the numeric keypad on the door, and her slender fingers danced like an elf, accurately pressing the corresponding numbers.

"Three, seven, six, four, five, one, six, nine..." Qiu'er pressed the numbers while reciting silently in her mind to make sure everything went well.

Soon, all sixteen numbers were entered, and the metal door made a slight "buzzing" sound, as if verifying the correctness of the password.

"Insert the yellow key and turn right two and a half weeks." Han Yu's voice sounded again, clear and steady, guiding the next operation.

Lan Luoluo, who was standing nearby, heard this and immediately took out a yellow key from her storage soul guide. The key had an ancient shape, with complex patterns carved on it, and emitted a faint soul power fluctuation. She carefully inserted the key into the keyhole on the metal door, and then slowly rotated it to the right for two and a half weeks according to Han Yu's instructions.

“Knock, knock, knock…”

As the key turned, crisp mechanical sounds came from inside the metal door, as if a sleeping beast was waking up. After three soft sounds, the door that was originally tightly closed actually slightly opened three inches outward, and the soul guide ray holes that were previously opened also closed, as if a beast had retracted its fangs and temporarily lifted its alert state.

"Chi--"

With a slight sound, as if some pressure was released, the metal door finally bounced open completely, revealing a deep passage.

Seeing this, Xiao Xiao, who was standing nearby, could not help but exclaimed: "What an ingenious soul guide device! This level alone would be difficult to pass if we didn't know about it in advance."

Han Yu smiled and said, "This is nothing, there are more powerful ones to come. After all, this level of protection can only be used against soul masters below the Soul Emperor level. The truly strong can break in with brute force. You have also seen the extent of these mechanisms, so you must be more careful later. Let's go."

Lan Luoluo nodded, still walking in front and entering the portal first.

After entering the portal, the three women were surprised to find that this was actually an enclosed space of about 20 square meters.

The walls, the floor, and the ceiling were all made of solid rock. There were no windows, no passages of any kind, only depressing darkness and silence.

Han Yu's eyes swept around and finally landed on the left wall, where there were three yellow bricks that were slightly different in color from the surrounding rocks, arranged in a triangle shape. He pointed at the three bricks and said to Qiu'er, "Qiu'er, hit the three yellow bricks, the first one three times, the second one five times, and the third one once."

Qiu'er was so fast that almost as soon as she finished speaking, her figure turned into a trail of afterimage and rushed towards the three yellow bricks like lightning. She completed Han Yu's command in just a few blinks of an eye.

With a slight vibration, the door we entered slowly closed, as if a steel gate was isolating us from all the noise from the outside world.

At the same time, a circle of yellow light lit up around the top, and the dim light added a bit of mystery to this enclosed space.

The vibration became more and more obvious, and my body seemed to lose weight, and a feeling of weightlessness arose spontaneously. "Is this... we are descending?" There was a hint of doubt in Lan Luoluo's voice, and she turned to look at Han Yu for an answer.

Han Yu nodded slightly, confirming her guess. "This place has a much higher defense level than Mingde Hall, and it is even a hundred meters underground."

He paused and continued, "The area within several thousand square meters is filled with various trigger-type soul guides, which can be said to be impregnable.

If we don’t enter through this large elevator, even a level nine fixed-type soul guide shell won’t be able to break through the defenses above.”

The elevator continued to descend for about twenty seconds, and finally came to a slow stop with another slight vibration.

"Get ready for battle, two people. Luo Luo on the left, Qiu'er on the right." Han Yu's voice was low and calm, carrying an unquestionable order.

As soon as he finished speaking, the elevator door slowly opened, and a teasing voice came from outside: "Hey, why did Manager Li come down at this time? Are you here to bring us some wine?"

A golden light flashed in Han Yu's eyes, and two muffled groans sounded almost at the same time, and the soul shock was launched instantly! Although he only had a spiritual body and could not exert the true power of the soul shock, it was enough at this time.

Qiu'er and Lan Luoluo reacted quickly and rushed out like arrows.

The golden dragon spear in Qiu'er's hand flashed with light, and went straight to the opponent's vital point; Lan Luoluo stretched out her right hand, with light surging in her palm, obviously she was going to use her signature skill - Light Destroying Demons.

The two figures obviously did not expect us to launch a sudden attack. The triggered soul guide shields on their bodies had just popped up when they were pierced by the two women.

The golden dragon spear was unstoppable, and the light of demon-breaking was extremely domineering. The two middle-aged men didn't even have time to scream before they fell to the ground unwillingly under the attacks of the two women.

"They are level six soul masters..." I was secretly shocked, remembering what Xu Tianran once said to Orange: If a soul master is prepared, he is not afraid of soul masters of the same level, and he even has an advantage when his level is lower... In sudden encounters, soul masters show a faster reaction speed than soul masters.

Qiu'er and Lan Luoluo quickly resolved the battle by relying on their special ability to break through the soul guide shield.

Lan Luoluo's figure flashed and turned into a blue phantom. She went around behind a soul engineer and waved her slender hand. A sharp soul blade instantly cut through the opponent's shield. Then she slapped him on the back and knocked him to the ground.

On the other side, Qiu'er displayed amazing strength. Facing the attack of another soul engineer, she did not dodge or evade, but directly punched out. The golden soul power turned into a roaring giant bear, smashing the opponent's attack and shield together. The huge impact force knocked the soul engineer away, and he fell heavily to the ground and lost consciousness.

Before the two level six soul masters could react, they fell to the ground and became cold corpses. Qiu'er clapped her hands, as if she had just done something insignificant, while Lan Luoluo elegantly tidied up the hem of her skirt that was slightly messed up by the battle. They both looked at Han Yu at the same time, waiting for his next instruction.

Han Yu's eyes swept across the corridor. The corridor seemed a little empty. Soul guide lamps emitting soft light were hung on the walls on both sides, illuminating the road ahead.

At the end of the corridor, about ten meters away, stood a huge double metal door, blocking their way.

"Each of the two people has a key. Find them out." Han Yu's voice echoed in the empty corridor.

Qiu'er and Lan Luoluo did as they were told and searched the two bodies separately. They soon found two quaint metal keys.

"Walk along the left side of the passage. Remember, your steps cannot exceed two feet horizontally." Han Yu said in a deep voice with a serious expression.

The three women did not dare to delay. Following Han Yu's instructions, they carefully moved forward along the left side of the passage, precisely controlling each step within a two-foot horizontal range, and finally arrived in front of the huge metal door.

The gate is towering into the clouds. It is about four meters high and more than three meters wide. It is made entirely of thick metal and appears extremely heavy.

There is no decoration on the surface of the door, only a bright red danger symbol, a peculiarly shaped three-pronged keyhole, and a row of flashing password buttons, foreshadowing the unknown danger hidden behind the door.

"Insert the key first this time."

Han Yu pointed to the three-pronged keyhole on the gate and explained in detail, "Lolo, insert the key you found into the lower left position of the fork, Qiu'er, insert the key you found into the lower right position.

Qiu'er, find another black key from Li Chong's key bunch and insert it into the fork above.

Remember, the three keys must be put together first, and then inserted into the keyhole together."

The deeper they went, the more frightened they became. It was only then that they truly understood why Han Yu had to take the risk of separating a spiritual clone to follow them.

Every mechanism and every step here is full of danger. If you are not careful, you will trigger a deadly trap. You must be cautious and act with all your heart, without making any mistakes. If it weren't for Han Yu's spiritual detection and guidance, they would never have been able to get here.

Thinking of this, they couldn't help but sincerely admire Han Yu's strong memory that allowed her to remember everything she saw.

Han Yu motioned Qiu'er to come forward and insert the three keys into the three locks on the door.

The moment the key was inserted, a slight mechanical sound was heard and the door trembled slightly, as if some complicated mechanism was operating inside.

Then, a square metal plate lit up in the center of the door. Many tiny buttons were densely arranged on it, and each button was engraved with a number or symbol.

Han Yu whispered a complex password, which had thirty-two digits in total, making Qiu'er dizzy.

She followed Han Yu's instructions and pressed the corresponding buttons one by one. Every time she pressed a button, the metal plate made a slight "drip" sound.

When the last button was pressed, the metal plate went out instantly, and the door made a dull "boom" sound and slowly opened to both sides.

A faint metallic smell wafted towards me, carrying a hint of coldness and heaviness.

Lan Luoluo and Xiao Xiao were fine, as they were not soul masters and were not sensitive to metal.

But Han Yu's spirit body seemed to be given a shot of chicken blood, and was so excited that it almost trembled.

His mental power surged out like a tide, instantly enveloping the entire warehouse.

This is a huge warehouse with no end in sight. It is roughly estimated to be at least 10,000 square meters.

The lights in the warehouse were bright, illuminating the mountains of metal boxes. These boxes were of different sizes and shapes, neatly arranged in a certain pattern, emitting a cold luster.

Han Yu's mental power penetrated the barrier of the box and saw various rare metals piled up inside.

These metals sparkle with various colors, some are silver-white like snow, some are red like fire, some are black like ink, and some are light green like jade, emitting charming brilliance.

He made a rough estimate and found that there were at least tens of thousands of tons of rare metals here, with as many as thirty-two types. Although none of them were particularly rare, their large quantities were enough to make him rich enough to rival a country.

"Wow, so many rare metals, can we start working?" Lan Lolo lowered his voice, his eyes flashing with excitement, and he rubbed his hands impatiently.

Han Yu shook his head and said solemnly in a low voice: “Don’t be anxious, this place is not that simple.

This warehouse is full of traps, and the slightest mistake will trigger the alarm, and these metals are not the most precious ones."

Lan Luoluo's curiosity grew when he heard this, and he asked, "Is there any more precious treasure? More powerful than these shiny pieces of metal?"

Han Yu nodded and explained in a low voice: "Think about it, this is the underground warehouse of the Sun Moon Empire. It must be storing strategic materials. How could there be only these ordinary rare metals?" (End of this chapter)
