On the Ling Family's side, Ling Nanqin was looking in the direction of the Thunder Cave Mountain with some worry.

Ling Rong said: "Miss Qin, we don't need to wait anymore. Lingyun this brat actually disregarded my advice and wholeheartedly ran into the cave. I couldn't even stop him, he's probably already in the Thunder Lizard's stomach now."

At that time, Ling Nanqin was leading the group, walking at the very front, and did not notice Ling Rong's sneak attack on Ling Yun. As a result, she did not know that it was Ling Rong who framed Ling Yun.

"Ai, his life and death can only be left to fate. Let's go."

"..."

Within the mountain.

Ling Yun was searching for another way out of the Thunder Lizard Tomb.

But after searching for half a day, he still couldn't find anything.

This cave was a dead end! The only way out was through the passage they had come through.

Ling Yun returned to the front of the passage, and suddenly, his expression changed!

From the other side of the crater, there came a series of whooshing sounds, as if something was digging in the rock.

Lingyun secretly activated the Sacred Thunder Crossing Technique and sensed that on the other side of the collapse, the Human Stage Level 6 Golden Thunder Lizard had already returned.

Furthermore, the Thunder Lizard was trying to dig up the fallen rocks. Although it would take some time to dig it out, at this rate, the Thunder Lizard would come in sooner or later!

However, the only good news was that the Thunder Lizard's aura was much weaker than before, and it was estimated that it only had the strength of a Human Stage Level 5.

It seemed that the Thunder Lizard had also suffered heavy injuries during its pursuit of the disciples of the Ling and Yu Families.

"There really is no path to heaven and no door to hell. The only way to survive is to fight it out with this Lightning Lizard!"

"We can't just sit there and wait for death. We have to take advantage of the time we have left to increase our strength."

Ling Yun's face revealed a determined look. He turned around resolutely and returned to the primeval pool.

"Hua la!"

Ling Yun immediately jumped into the Primordial Liquid.

"Holy Lightning Crossing Disaster Spell!"

Lingyun chanted it in his heart and activated the Holy Thunder Crossing Disaster Spell. Lingyun's body suddenly produced a strong suction force, absorbing the Essence in the reservoir.

As the huge amount of Yuan Power entered his body, a new lightning Yuan Power started to form in his body's channels and finally converged at his lower abdomen's Dantian.

"Mid Rank Third Stage of the Mortal Origin Stage …" The strength of 35 Flood Dragons! "

"Late stage of the third level of the Mortal Origin Stage …" The strength of 38 Flood Dragons! "

"..."

"Peak of the third level of the Mortal Origin Stage, the strength of 39 flood dragons!"

The Saint Thunder Crossing Disaster Art did not disappoint Lingyun. This cultivation technique was just too powerful. It could be called a demonic level cultivation technique, and the speed at which it was being cultivated was incomparable to any other cultivation technique.

Ordinary people would need a few months or even a year and a half to accumulate and refine their elemental energy, but this was not a problem for Ling Yun.

As long as there was enough heaven and earth origin energy, Ling Yun's cultivation could increase explosively at a terrifying speed.

This was a life-and-death battle.

It would be up to the Thunder Lizard to open up the collapsed passageway first, and Lingyun to raise his strength to the extent that it could rival the Thunder Lizard.

A day later, the sound from the other side of the tunnel became louder and louder. Clearly, the Thunder Lizard was about to succeed.

Under this kind of pressure, Ling Yun's potential was actually stimulated.

Finally, the thunder energy in Lingyun's dantian broke through a bottleneck and officially entered the fourth level of the Mortal Origin Stage!

Although it was only the fourth stage, Ling Yun's cultivation base was at the fifth stage of the Mortal Origin Stage.

Now, Lingyun finally had the confidence to fight against the Thunder Lizard.

The aura of the Thunder Lizard had weakened, as its strength had obviously decreased due to its injuries. It was probably only equivalent to a human warrior at the fifth level of the Mortal Origin Stage.

However, there was one thing that could not be overlooked. The body of the Thunder Lizard was extremely tough, its scales were indestructible, and in terms of defense, it was not much weaker than Lingyun's middle grade Essence Armor.

"Not enough! I have to continue to become stronger. "

"..."

After another half a day, suddenly, a loud sound came from the other side of the tunnel. Immediately afterwards, a seven to eight meter long giant thunder lizard appeared in Lingyun's line of sight.

"Hiss hiss."

The Thunder Lizard's tongue was long and thin, and its teeth were sharp and sharp. Saliva dripped from its sawtooth-like mouth, and its black scales exuded a chilling light.

However, on the Thunder Lizard's scales, there were many scars.

Some of the wounds even split open the scales, injuring the flesh and bones within.

It seemed that the Ling and Yu families had caused quite a bit of trouble for the Thunder Lizard.

"Is it finally here!?"

Within the Essence Pool, Lingyun suddenly opened his eyes, which were shining brightly. Within his eyes, a bright light shot out.

"Hua!"

The liquefied elemental liquid exploded once again, splashing water everywhere.

Ling Yun slightly exerted his strength and his body rose up from the ground. He elegantly landed beside the Essence Pool. Thunder essence seeped out from his body and instantly evaporated the green clothes.

The red eyes of the Thunder Lizard instantly locked onto Lingyun. This animal suddenly let out an angry roar, and with its four legs in the air, it charged towards Lingyun at an extremely fast speed.

Everything that blocked the path of the Thunder Lizard, including the gigantic white skeletons, was smashed into smithereens by this angry Thunder Lizard!

Seeing the power displayed by the Thunder Lizard, Lingyun was slightly taken aback.

"Fortunately, this Thunder Lizard is injured and not at its peak condition. Otherwise, with its 60 Flood Dragon strength, I would absolutely not be its match right now." Even now, it still has nearly fifty Flood Dragons worth of power. "

Lingyun had a rough understanding of the power of this Thunder Lizard.

"Let me fight with a monster like you!"

Lingyun's heart was filled with a heroic spirit, his black hair fluttered without wind, giving him an aura of elegance.

If this had happened in the past, then he would only have been able to run for his life when he saw this monster. But now, he had officially embarked on the path of martial arts. This Thunder Lizard was the challenge and obstacle on his path of martial arts.

He only had two options, to step over or be smashed to pieces by it.

"Roar!"

In a split-second, the Thunder Lizard charged forward in a domineering manner.

"Come at me!"

A frenzied battle intent gushed out from Lingyun's eyes. He actually charged towards the Thunder Lizard in a head-on manner.

"Reckless Bull Fist!" The Savage Bull's Arch! "

Lingyun lowered his weight, and then suddenly punched upwards with both fists, just like a raging bull.

A shockwave exploded at Lingyun's fist point, shooting straight towards the Gold Swallowing Thunder Lizard.

The blast cleaved through the air, vaguely forming the shape of a two to three meter tall raging bull that collided with the Goldbiter Thunder Lizard.

"Bam!"

An earth-shaking explosion suddenly erupted within the enormous cavern, causing the entire cavern to shake.

A circular shockwave visible to the naked eye spread out at the point where the two collided. Under that frightening energy ripple, all the nearby white skeletons were completely destroyed!
