Empress: My husband is too strong, I can only lie down and relax.

Chapter 563 The Blood of the Demon Lord!

This time, the restriction was broken very quickly; in almost a moment, the restriction on the black tower was broken.

The black tower's door slowly opened with a humming sound, and an even denser surge of demonic energy instantly poured out.

Even with Gu Jiancheng's Yin-Yang dual protection, Huangfu Shan and the others still couldn't help but frown.

The demonic energy was so cold that they couldn't help but take a few steps back.

Zhao Tianxiang, on the other hand, didn't seem to feel anything.

Even though the Black Tower was open right in front of her, she didn't dare to enter it. Instead, she looked at Gu Jiancheng.

"Hehe, it's alright, it's very safe inside, you can go in now!"

Gu Jiancheng smiled.

"it is good!"

Thus, Zhao Tianxiang cautiously stepped into the Black Tower.

Immediately, Gu Jiancheng raised his hand and enveloped Huangfu Shan and the others with more Yin and Yang energy, which made the women feel much more comfortable.

Otherwise, these terrifying auras would make them quite uncomfortable.

Immediately afterwards, Gu Jiancheng led everyone into the Black Tower.

At this moment, Zhao Tianxiang had already arrived inside the Black Tower and was standing in front of a skeleton, staring blankly at a drop of blood on the skeleton.

"The Demon Lord's Blood!?"

When Huangfu Shan came over, she couldn't help but gasp when she saw the blood.

The blood floated on the skeleton; though it was only a tiny drop, it seemed to contain boundless energy!

A single drop of Demon Lord's blood will fully activate the demon bloodline within Zhao Tianxiang, and may even grant her the potential to advance to the rank of Immortal Lord.

No wonder Zhao Tianxiang insisted on coming to this Taoist temple to search for treasures.

"My Zhao family has been waiting for this drop of blood for a long time."

At this moment, Zhao Tianxiang suddenly spoke up, saying, "In that case, you can take whatever you want with you, except for this drop of blood and the bones."

"Ok!"

Gu Jiancheng nodded.

In fact, the Demon Lord's remains and blood were of no use to them.

Immediately, Gu Jiancheng and the others looked around and discovered that there were a total of eight niches on the walls of this black tower space.

Each niche contains a treasure.

It seems this is the collection of the Immortal Lord from back then.

"Everyone can choose what they like," Gu Jiancheng said with a smile.

"okay!"

The three women nodded, and then dispersed in different directions.

Gu Jiancheng went straight to one of the niches.

Inside the niche lay a jet-black stone that shimmered with lightning.

The moment Gu Jiancheng entered, he noticed the stone.

Immediately, Gu Jiancheng went directly to the stone and stared at it. He was shocked to find that the lightning on the stone was all black, and the energy within it was extremely violent, with an aura almost comparable to that of a Celestial King!

After the system scanned the data, the information appeared before my eyes.

"Fallen Thunder Crystal?"

Looking at the information displayed on the system, Gu Jiancheng couldn't help but stare intently.

The quality of this stone has actually reached the level of a half-step Immortal King!

Moreover, it can also be used for weapon crafting.

This is perfect for upgrading the Human Emperor Sword.

Although the Human Emperor Sword had already been upgraded once before, Gu Jiancheng's cultivation and combat power had improved far too quickly.

Although he ultimately won the final battle against the Demon King, it still caused cracks to appear in both of the Emperor's Swords.

Facing the power of a Celestial King, it's still too much to ask of this Human Emperor Sword.

The fact that it didn't shatter already indicates that the Human Emperor Sword has a good foundation.

Thus, Gu Jiancheng put away the Fallen Lightning Crystal almost without any hesitation.

During his upcoming period of seclusion, Gu Jiancheng's primary task was to upgrade the Human Emperor Sword once again.

Meanwhile, Huangfu Shan and her group had already looted all the other treasures.

Zhao Tianxiang carefully collected the Demon Lord's blood and bones.
