The secret room could not see the sky, but how could Mu Xiaoling and Xiao Yu, the one who had fused with the heaven and earth because of the [Skydark Mantra] and the famous Demon Marshall Wu Yuan, not see the situation in the sky?

The black clouds condensed, lightning flashed, and thunder rumbled. In that instant, a lightning bolt as thick as an arm struck the ground, but not a single trace was left.

But this was only the beginning.

Another bolt of divine lightning, this time five times thicker than the previous one, ruthlessly struck the ground.

However, the ground was as hard as steel. Even though the lightning had struck the grass, it only left a white mark on the ground. The underground palace only shook a few times before it passed.

The third bolt of lightning immediately followed. This time, it was five times thicker than the first one and it crashed into the ground with a loud bang.

This time, the entire ground shook, and the underground palace was shaking violently. The demons in the underground palace were unable to stand up and rolled back and forth on the ground.

However, not a single stone shard fell from the entire underground palace.

When Mu Xiaoling saw this, she finally understood why Xiao Yu was so confident. This was the Heaven Swallowing Python's sealed grounds. How could a Supreme Elder from the upper realms be so easily split apart?

At that moment, the Kun Heavenly Furnace's color changed once again as it was being burned by the demons. It actually started to gradually turn blue. When Xiao Yu saw this, he knew that it was time, and threw his Black Dragon Claw into the Kun Heavenly Furnace.

With a crashing sound, the black dragon claw seemed to have entered a frying pan. It actually almost flew out of the furnace, but was forcibly pushed back by Xiao Yu's true essence.

"The Limitless Divine Mine is a top-grade divine mine that is naturally nurtured by the heavens. This Black Dragon's claw is the claw of a black dragon from the underworld, so it's not strange that it's hard to fuse the positive and the evil. That's why it requires the white skin to reconcile." Xiao Yu already knew this would happen, and wasn't surprised at all. He took out a white tiger skin from his spatial ring and threw it into the Heaven Seeking Furnace, then increased its firepower.

The Kun Tian Cauldron that was shaking started to stabilize.

Xiao Yu closed his eyes once again and silently instigated his primeval essence to feed the sacred fire to the demons.

Mu Xiaoling felt the changes in her surroundings as the true essence within her body churned like Xiao Yu's true essence. It was as if a wave had lifted her up as she bravely advanced forward, breaking through the barrier just like that and reaching the seventh level of the Fighter.

However, the momentum did not stop there. He continued to rush forward and arrived in front of the Level 8 Fighter barrier.

Perhaps it was because she broke through too quickly, the barrier was actually even thicker than the city walls. It was simply impossible to break through.

Sure enough, when the waves crashed into the wall, not a single trace was left behind as she quietly retreated.

Mu Xiaoling looked at the barrier that was as thick as a city wall and understood that she couldn't rush it. However, she was told by a voice that she could and the opportunity to break through was right in front of her.

Mu Xiaoling believed in her intuition. She had been saved by it countless times in the past.

She sat down in front of the barrier and once again blended into the world.

She could see that Xiao Yu was still activating his True Essence and see the lightning in the sky rolling down one after another, yet there was nothing she could do about it.

Heavenly Thunder …

Mu Xiaoling's eyes lit up. If he were to use the power of heavenly lightning to break through the barrier, then perhaps he would have a great chance. However, this move of his was somewhat risky.

But isn't surviving in this world just an adventure?

She formed her true essence into a needle shape and stabbed it into the ground. The power of thunder immediately followed the true essence and entered her meridians. Instantly, her entire body felt a burning pain.

The meridian that was struck by lightning immediately became fragile, and then it was immediately repaired by true essence that was a step too slow. The meridian channels in her entire body were destroyed on one side, and they were also repaired on the other. That feeling was like she was in hell, suffering the most brutal punishment.

But then, she could see that her meridians were opened up by the heavenly thunder. If her meridians used to be like small streams, then now they were like rivers, and more true essence flowed along with them. At the same time, the amount of spirit energy she absorbed also increased.

Even though it was hard to endure like this, there were many benefits.

Mu Xiaoling clenched her teeth as she used the Heavenly Lightning Force to walk around her body until she reached the barrier.

The heavenly thunder continued to hack at the barrier like a hot knife through butter. The barrier behind the barrier seemed to be unable to withstand the power of the heavenly thunder and began to slowly soften and dissolve.

After the two phases were melted, the barrier became thinner and thinner, and the power of the divine lightning also became lesser and lesser. In the end, it disappeared together.

An enormous wind and rain swept through the broken barrier, instantly filling the entire Dantian, and actually began to liquefy gradually, as if it was really storing seawater.

Mu Xiaoling had just reached Fighter 8-dan, but no one had ever said that her strength would liquefy after reaching Fighter 8-dan. It was very strange.

She slowly opened her eyes and met Xiao Yu's eyes that were filled with worry.

Xiao Yu heaved a sigh of relief, and he didn't change his speed of rushing into True Essence, and he couldn't help but admonish, "Nonsense!"

"What's wrong?" Mu Xiaoling was startled as he didn't understand what was going on.

"You dare to provoke the lightning at your level of cultivation, what else could it be other than fooling around?" Xiao Yu sighed, simultaneously controlling two divine artifacts. Even he himself would have been at a loss if he had been in the middle of controlling one or two of them, but who knew that just as he was lost in thought, he felt a sliver of divine lightning energy flow into the secret room. After he saw what Mu Xiaoling had done, he almost lost control of his strength and exploded the furnace.

At this moment, Mu Xiaoling knew how dangerous what she had just done was. "I'm sorry."

Xiao Yu couldn't help but sigh. Only the heavens knew if he'd woken up to sigh more than when he'd shocked the Three Realms five hundred years ago.

Forget it, how could he not know his Ling'er's character?

At this moment, the Heaven Seeking Furnace swayed again. Xiao Yu felt that it was almost done, so he said to Mu Xiaoling, "I must stay here for the next forty-nine days. You don't have to accompany me like this."

Mu Xiaoling shook her head. "I will stay here. I'm not going anywhere."

Xiao Yu lightly smiled. He felt as if he'd eaten honey in his heart. It was sweet to the point his heart trembled, and he wished for nothing more than to hug her and love her dearly.

Mu Xiaoling turned her face away as she felt a little tipsy from his stare.

Xiao Yu laughed lowly, then closed his eyes and sent his Spiritual Sense into the Heaven Seeking Furnace. He used his True Essence to drag the liquid within the furnace, gradually forming the shape of two daggers.

He couldn't rush this step. He had to do it bit by bit.

The continuous thunder and lightning above caused the underground palace to be in a state of turmoil. At any moment, people could be thrown into confusion. Little Qing would bring food and medicine to the people every day.

Mu Xiaoling didn't move at all after eating it, she continued to consolidate her cultivation that had just broken through. Occasionally, she would look at Xiao Yu in a daze.

At this moment, Xiao Yu's eyes were closed. He retracted the might he exuded as if he were no longer the aloof Demon Lord, but instead an extremely ordinary person. His long eyelashes covered his eyes and would occasionally tremble, causing one's heart to itch.
