If this underground palace could be entered, other ancient clans' underground palaces could be entered in the same way.
Several days later, the Grand Elder and Elder Lu Song arrived.
By this time, the Wu clan had also become history.
Even their underground palaces were guarded by experts dispatched by the Qin clan.
"You mean, the four of us can open this stone door?" The Grand Elder was shocked after hearing Qin Hanchu's explanation.
"We should be able to. As long as you buy me a moment's time, I can get in," Qin Hanchu said.
"There are many dangers in the underground palace. Be careful once you go in, and don't try to be brave," Elder Lu Song reminded him.
Qin Hanchu nodded, "Understood."
"Then we will lend you a hand. If you become stronger, our Qin clan will also be stronger," the Grand Elder said.
"I will return to the entrance at noon twelve days later. At that time, you will push open the stone door to receive me."
If the stone door opened on its own, it would automatically open at the appointed time to let the living warriors out.
However, since Qin Hanchu was forcing his way through the stone door, he had to exit in the same manner.
After agreeing on the time, the four began to work together to push the stone door.
As they poured their strength into it, the stone door's radiance intensified.
The gap between the two stone doors gradually widened.
Soon, a gap appeared in the middle of the two stone doors.
This gap was large enough for one person to enter!
Qin Hanchu gave the other three a look, then flashed inside without hesitation.
As Qin Hanchu left, Elder Lu Song's pressure increased, and the stone door on his side immediately sprang back.
But by then, Qin Hanchu had already entered.
The three then withdrew their strength, allowing the stone door to close.
"Will Hanchu be in danger?" The great-grandmother worried.
"He's already at the Martial King realm, so he should be fine," the Grand Elder said.
"Then let's cultivate and be ready to receive him in ten days."
After speaking, the three sat down cross-legged, guarding the entrance.
At this moment, Qin Hanchu had already entered the underground palace.
Inside the underground palace, there were ancient buildings.
The stone walls were also adorned with murals.
As he walked along, there was no danger.
It was clear that this place had already been explored by the Zhou family.
After walking for a full hour, Qin Hanchu stopped.
About ten meters ahead, there were three skeletons.
Beneath the skeletons was a large chest.
He hadn't seen any skeletons on the way here.
This indicated that there must have been danger at the location of these skeletons.
Qin Hanchu took out the strangely shaped key and whispered, "Could this key open this chest?"
Although Qin Hanchu was in the Martial King realm, he did not dare to venture in carelessly.
He pushed out a palm, then controlled his power to push the skeletons aside.
Controlling his power to wrap around the large chest, Qin Hanchu pulled forcefully.
With his movement, the large chest, as if pulled by a rope, moved towards Qin Hanchu.
*Whoosh!*
The moment the chest moved, hundreds of steel needles shot towards it.
These steel needles were extremely powerful; even a peak Grandmaster would struggle to withstand them.
*Clink, clatter...*
Hundreds of steel needles struck the chest, yet not a single scratch was left on it.
Qin Hanchu used his power to form a rope and dragged the large chest to himself.
Taking out the key, Qin Hanchu inserted it into the lock of the chest.
Before unlocking it, Qin Hanchu concentrated all his power into a defensive shield, guarding against any traps within the chest.
With a click, the chest's lock was opened.
As Qin Hanchu opened the chest, he immediately retreated.
Fortunately, he had been overly cautious.
There were no hidden mechanisms in the chest.
Qin Hanchu stepped forward and saw that the chest was filled with pieces of chainmail.
Picking up a piece of chainmail, Qin Hanchu struck it hard with the dagger given to him by Situ Guangtao.
To his surprise, the chainmail remained completely undamaged.
Qin Hanchu's dagger could cut through five centimeters of steel plate.
This showed just how hard the material of the chainmail was.
With this chainmail, it was equivalent to having an extra layer of protection.
After confirming that the chainmail was not poisonous, Qin Hanchu put on a set on the spot.
Although the style was a bit awkward, it was worth it for its high defense.
Taking the remaining chainmail out of the chest, Qin Hanchu disassembled the lid from the inside of the chest.
The lid of the chest had very strong defenses and could be used as a shield.
As for the remaining chainmail, he would decide whether to take it when he left.
Having added two layers of protection for himself, Qin Hanchu moved forward.
As soon as he reached the next hall, the sound of breaking wind was heard.
While Qin Hanchu used his defensive shield to block, he also held the chest lid in front of him.
*Ding ding ding...*
The steel needles struck Qin Hanchu's defensive shield and fell to the ground.
These things could no longer harm Qin Hanchu.
After walking for more than twenty meters, Qin Hanchu encountered three waves of steel needles.
At this point, skeletons appeared ahead.
The attire of these skeletons was clearly not that of modern people; they were likely the ancestors of the Zhou family.
Although they were dead, their skeletons still maintained a cross-legged sitting posture.
Scattered weapons were also found around the skeletons.
Qin Hanchu proceeded cautiously, but encountered no further traps.
He picked up a sword and blew the dust off its blade.
Even after thousands of years, the sword still gleamed with a cold light.
This demonstrated the immense power of the weapon.
Qin Hanchu held the long sword and carefully examined his surroundings.
Just then, he noticed a piece of yellow cloth in the embrace of a skeleton.
It seemed that something was wrapped within this yellow cloth.
Qin Hanchu opened the yellow cloth, and a yellowed book came into view.
"Giant Sword Slash!"
Seeing these three words, Qin Hanchu's heart skipped a beat.
Could this be a martial arts manual?
Qin Hanchu opened the book and saw that it indeed contained a martial arts technique.
Most importantly, it was a manual for the Martial King realm.
This book also recorded the power of the five elements.
Depending on the specific element, the Giant Sword Slash had different attack methods.
After carefully reading the book, Qin Hanchu put it into his embrace.
He only had ten days, and now was not the time to study it.
If nothing else, this martial arts manual alone was extremely precious!
"Let's see what good things you have!" Qin Hanchu, while remaining vigilant, opened the clothes of other skeletons.
On them, Qin Hanchu found several medicine bottles.
Unfortunately, the pills inside had turned to dregs, having expired.
Gathering the weapons on the ground, Qin Hanchu then continued to move forward.
Despite Qin Hanchu's caution, a stone slab under his feet suddenly sank.
The moment the stone slab sank, Qin Hanchu immediately retreated.
Simultaneously, green smoke suddenly emerged from all around.
Qin Hanchu knew it was poisonous gas, so he immediately activated his ice-cold power to completely isolate himself from the outside.
*Hiss hiss hiss...*
Although Qin Hanchu's ice-cold power was strong, he could still see his power being eroded.
Without the enhancement of his ice-cold power, even a Martial King would have to flee.
