The protective shield of the Martial King realm could be corroded, showing how terrifying this poisonous smoke was.
If it were a peak Grandmaster, they would surely die beneath this poisonous smoke.
It took a full five minutes before the poisonous smoke dissipated.
Qin Han Chu continued to recover his strength while marveling inwardly.
This poisonous smoke, after thousands of years, was still so terrifying.
If it hadn't been for the reduction of its toxicity over time, Qin Han Chu probably wouldn't have been able to withstand it either.
Holding up the lid of the chest, Qin Han Chu pressed onward.
Passing through the passage, another grand hall appeared before him.
In this hall, more than ten chests were piled up, and not far away lay more than ten skeletons.
Beside these skeletons were still some weapons, and on their bodies, Qin Han Chu found the keys to the chests.
In addition, Qin Han Chu also found a bamboo slip.
The characters on the bamboo slip were already somewhat blurred, but it should be possible to restore them with high-tech means after returning.
Putting away the bamboo slip, Qin Han Chu took the keys to the chests.
Qin Han Chu moved a distance away, then used the previous method to drag the chests one by one.
To Qin Han Chu's surprise, there were no traps this time.
All the chests had been moved, and nothing unusual happened.
Despite this, Qin Han Chu did not dare to let down his guard.
Holding a string of keys, Qin Han Chu tried them one by one.
With a click, the chest was opened.
Inside the first chest were several porcelain bottles.
Qin Han Chu opened one of the porcelain bottles and saw that it contained pills of Jade Marrow.
Most importantly, these Jade Marrow Pills were very well preserved.
They had not turned into medicinal dregs.
Qin Han Chu observed carefully and found that the jade bottles containing the pills seemed a bit special.
He took out several more bottles and opened them, discovering that they all contained Jade Marrow Pills.
Just these Jade Marrow Pills alone could greatly increase the strength of the Qin clan's Grandmasters.
Unfortunately, he could not open the main door yet, so Qin Han Chu could not take them all.
Putting the Jade Marrow Pills back into the chest, Qin Han Chu locked it directly.
Next, Qin Han Chu opened the other chests.
In these chests, Qin Han Chu saw many rare medicinal materials.
Some of them had already become extinct.
Unfortunately, most of these medicinal materials had rotted and were no longer usable.
Opening the last chest, Qin Han Chu found only five jade bottles inside.
Qin Han Chu picked up a white jade bottle, and saw the words "Cold Origin Pill" written on it.
"What is this?" Although Qin Han Chu possessed the Ancient Divine Medical Scripture, he had never encountered the name of this pill before.
As soon as Qin Han Chu opened the medicine bottle, he sensed an icy coldness.
This made Qin Han Chu's heart tremble.
He possessed the power of ice and cold, yet this pill in the bottle made him sense the cold?
Qin Han Chu capped the jade bottle, recognizing it as a treasure.
Qin Han Chu picked up the other jade bottles, and saw that they were labeled "Fire Condensing Pill," "Metal Sharpening Pill," "Green Wood Pill," and "Yellow Earth Pill!"
The five bottles corresponded to the five elements of power.
Qin Han Chu packed these five bottles into his backpack and decided he had to take them with him.
Passing through this hall, Qin Han Chu entered another passage.
After walking more than ten steps, Qin Han Chu stopped.
Before him was a stone door.
This stone door was tightly shut, with the words "No entry for non-clan members!" written on it.
And in the center of the stone door, there was a blood-red fingerprint!
This fingerprint seemed to be a reminder for the visitor to place their finger on it.
Qin Han Chu tried to place his finger on it, but there was no reaction.
"It can't be blood testing, can it?"
With that thought, Qin Han Chu bit his fingertip.
With the fresh blood, Qin Han Chu pressed his finger on it again.
This time, the stone door glowed.
But immediately, a sense of crisis enveloped him.
Without hesitation, Qin Han Chu quickly retreated.
Just then, countless "long needles" shot out from above.
Qin Han Chu hurriedly raised the chest lid in his hand.
To Qin Han Chu's shock, these long needles pierced through the chest lid.
Fortunately, Qin Han Chu still had his protective shield.
When Qin Han Chu retreated from the passage, the chest lid in his hand was riddled with holes, and dozens of long needles were even stuck in it.
If not for the chest lid blocking these long needles, Qin Han Chu's protective shield would definitely not have been able to withstand them.
Even with Qin Han Chu's powerful strength, he would have died on the spot.
Qin Han Chu pulled out a long needle, only to see that it was golden all over.
Holding it in his hand, he felt a sharp sensation.
Qin Han Chu flicked it casually, and the golden long needle transformed into a golden light, shooting towards an empty chest in the distance.
With a bang, the chest was pierced through.
Qin Han Chu's eyes widened in shock. What material was this long needle made of?
His own sword could not cut through that chest, yet this long needle could pierce it directly!
This was a treasure!
Used for sneak attacks, even a Martial King realm expert couldn't block it!
With that thought, Qin Han Chu quickly removed the long needles from the chest lid one by one.
He reached into the passage and grabbed some long needles from the ground.
He rolled these long needles in a cloth strip and carefully placed them into his backpack.
Looking at the stone door in the passage, Qin Han Chu fell silent.
Who would have thought that this stone door could detect that he was not a member of the Zhou family?
Did this stone door have a gene testing function?
Regardless, Qin Han Chu could only stop here.
He hoped that the Zhou family members had not been wiped out!
Next time, he would try to capture a Zhou family member to test it.
Packing the more than ten bottles of Jade Marrow Pills into his backpack, Qin Han Chu carried two sharp swords and walked towards the entrance.
Qin Han Chu knocked on the stone door a few times, intending to contact his great-grandmother and the other two on the other side.
However, there was no response.
Since he couldn't open the door in advance, he would cultivate here.
Looking at the Cold Origin Pill in his hand, Qin Han Chu was very conflicted.
This thing might enhance his strength, but Qin Han Chu dared not try it rashly.
Even if he wanted to try, he needed someone to guard him.
Putting away the Cold Origin Pill, Qin Han Chu took out the giant sword Zhan he had obtained earlier.
With nothing to do, he decided to cultivate the martial arts secret manual.
Sitting cross-legged on the ground, Qin Han Chu circulated the power within his body according to the records in the secret manual.
In the beginning, Qin Han Chu found it difficult to understand the principles of the martial arts moves.
But with repeated attempts, he gradually grasped the secrets.
A week later, a giant sword several meters long suddenly condensed above Qin Han Chu's head.
This giant sword was snow-white and exuded a chilling aura.
"Go!" With a shout from Qin Han Chu, the giant sword flew out instantly.
Before Qin Han Chu could react, the giant sword slashed at the ground.
Boom!
A burst of cold air erupted, and ice cones filled an area of dozens of meters!
The power of this blow was truly terrifying!
Of course, this blow also consumed a great deal of power.
With Qin Han Chu's current strength, he could only unleash the giant sword Zhan at most twice!
This move could only be used at critical moments.
Memorizing all the contents of the book, Qin Han Chu actually shattered the secret manual into powder.
One must remain vigilant!
It was best to keep such a martial arts secret manual as his trump card for now.
