Mu Lianqing said, "Lu Daoyou, the second level below is a thunder pool, you only need to stay in it for ten breaths, and you will pass the level, but this level is extremely dangerous, you should do what you can." ”

Lu Chen nodded.

Mu Lianqing immediately took out seven thumb-sized cyan stones from the storage ring.

Although these stones were small in shape, Lu Chen found that they contained infinite thunder power.

Old Peng's eyes were full of color, and he asked, "Mu Daoyou, this is not the legendary Thunder Pattern Immortal Stone. ”

Mu Lianqing's voice was calm, and he said slowly, "It's this stone." ”

Lu Chen asked, "Elder Peng, are the Thunder Pattern Immortal Stones very rare?"

Peng Lao said, "Legend has it that this stone is a remnant of the ancient immortal realm, anyone who can communicate with these thunder pattern immortal stones, can absorb the power of thunder and lightning contained in it, if you are lucky, you can master the power of the nine-point thunder law, I didn't expect that the east of the Mu family, there is such a treasure." ”

Lu Chen's heart moved, he had already mastered the origin of thunder for a minute and a half, if he absorbed all the thunder and lightning in these thunder pattern immortal stones, he might be able to make the thunder wood seedlings evolve again.

I saw Mu Lianqing throw these seven thunder-patterned immortal stones into the open space in front of him.

These thunder-patterned immortal stones suddenly enlarged in mid-air, turning into seven boulders, about dozens of zhang in height.

Seven cyan rays of light suddenly flew out from these boulders, and after connecting together, they turned into a cyan thunder pool.

The moment the thunder pool appeared, the entire space was filled with an incomparably violent cyan thunderbolt.

"Lu Daoyou, please enter the Thunder Pool!" Mu Lianqing said loudly.

In the thunder pool, the cyan thunder and lightning have condensed into a liquid state, reflecting sparkling waves, and the surface of the pool is even more staggered, constantly making a crackling and bursting sound.

As soon as Lu Chen entered the thunder pool, it was like water droplets splashing into an oil pot, and the entire thunder pool was boiling.

The liquid thunder and lightning in the thunder pool churned in an instant, flooding with layers of thunder waves, surging wildly towards Lu Chen.

Half of Lu Chen's body was immersed in the thunder liquid, not moving at all, allowing these thunderbolts to fall on him.

Wisps of cyan thunder swam on Lu Chen's body, flashing with dazzling light between the collisions.

At this moment, Lu Chen's eyes were tightly closed, and when the thunderbolts just penetrated his body, they almost broke his entire meridians.

The pain that the Thunder Pool refines the body, and the physical body needs to endure is unimaginable, and almost no one can survive ten breaths under this purest Nine Heavens Thunder Wash, which is also the reason why the Dragon Shadow Saint Venerable set the rule of this second level as staying in the Thunder Pool for ten breaths.

But for Lu Chen, these thunderbolts were the fertilizer for the seedlings of the origin of thunder in the primordial gods, so there was no pain on his face at all.

Mu Lianqing and Peng Lao looked at Lu Chen in the thunder pool from a distance, their faces nervous.

The thunder liquid rolled wildly and surged, turning into a whirlpool of thunder and lightning, and there were flashes of lightning in it.

Lu Chen was surrounded by these thunder and lightning vortexes, his eyes suddenly opened, and he roared in his mouth, "Suck!"

These whirlpools spun rapidly, and the wisps of thunder power visible to the naked eye in the thunder pool surged rapidly and were sucked into it.

The thunder liquid in the thunder pool turned into the purest thunder power at this moment, gathering from all directions, drilling into Lu Chen's body through these whirlpools, and then quickly gathering towards the thunder fire origin seedlings in his primordial god.

There is no need for Lu Chen's manipulation and guidance at all, and the Thunder Fire Origin Seedlings are constantly absorbing the power of thunder.

One breath.

Five breaths.

Ten breaths.

A quarter of an hour.

Three quarters of an hour.

Six quarters of an hour.

An hour later, the power of thunder in the entire thunder pool had been absorbed.

Lu Chen, with the late stage of the transformation of the gods, stayed in the thunder pool of the legendary thunder pattern immortal stone illusion for a whole hour, which was really beyond the imagination of Mu Lianqing and Peng Lao, and at this moment, the hearts of the two old men were shocked beyond measure.

And it seems to them that all this is not over yet.

At this moment, the seven thunder pattern immortal stones burst out again with dazzling light.

I only saw that a black pressure suddenly appeared in the void, and a purple thundercloud seemed to cover the sky.

The thunder in the thundercloud surged, only to hear a loud boom, and purple thunder and lightning smashed down in the direction of the thunder pool.

A moment later, tens of thousands of lightning bolts had fallen.

It turned out that this was the Thunder Pattern Immortal Stone to communicate the aura of heaven and earth and supplement the power of thunder in the Thunder Pool.

In the next moment, a pool full of purple thunder liquid appeared in the thunder pool again, and the thunder power contained in it was even more tyrannical.

At this moment, there was a faint sound of thunder from the ancient immortal realm in the thunder pool.

The purple thunder liquid churned and surged, and the waves were several feet high.

A thunder dragon phantom suddenly drilled out of the thunder pool, opened his mouth and inhaled, and an extremely dense thunder light immediately erupted above the thunder pool, and the purple thunder and lightning gushing out of it kept being sucked into its mouth, and this phantom became more and more condensed, and its size skyrocketed to the size of dozens of zhang.

This Thunder Dragon Phantom is the fusion of the seven thunder spirits in the Thunder Pattern Immortal Stone.

"Roar!"

The thunder dragon roared and roared seven times in a row, and after the seventh sound, the color of the seven thunder immortal stones was dim, but the power of the thunder in the thunder pool had reached an earth-shattering level.

The Thunder Origin Seedling in Lu Chen's primordial god seemed to sense the existence of the thunder dragon, and suddenly burst out with a dazzling light.

At this moment, Lu Chen's eyebrows flashed with thunder, and suddenly, the Lei Mu Origin Seedling came out directly!

Above the thunder pool, a towering tree about 100 zhang high suddenly appeared, and the purple rays on it swam, and the whole body exuded a thunder power of heaven and earth.

The thunder dragon's entire body rushed out, facing the thunder tree phantom, and opened its mouth to spit out a large area of purple thunder light.

These thunder rays fell on the Thunderwood Phantom and were instantly absorbed, and the half of the thunder patterns on the main trunk of the Thunder Fire Origin Seedling became larger at a speed visible to the naked eye, and there was a tendency to faintly turn into a whole thunder pattern.

Seeing that his attack did not pose any threat to the giant tree, the thunder dragon roared in anger.

The thunder dragon is just the phantom of the thunder spirit of the thunder pattern immortal stone, not the real thunder dragon.

At this moment, a voice kept emerging in his soul, as long as it could devour the thunder tree in front of it, it could become a real thunder dragon.

No one could resist the temptation of such a god-rebellious chance, and the greed in the thunder dragon's eyes became stronger and stronger, and soon, it roared and roared towards the thunder tree phantom.

The huge body of the thunder dragon was just wrapped around the thunder wood phantom, but it felt a supreme thunder power on the giant tree that was enough to make the depths of its thunder soul tremble, and the thunder dragon was suddenly frightened.

Just as the thunder dragon wanted to escape from the thunderwood, an astonishing suction suddenly erupted from the main trunk of the thunderwood.

The thunder dragon was horrified in his heart, roaring in fear, and wanted to leave the thunderwood immediately, but no matter how it struggled, it could not get rid of this suction, and finally, the thunder dragon found the source of its fear, and in this suction it sensed the breath of the thunder origin seed.

The Origin Seed of Thunder, which is enough to suppress all thunder and lightning.

Although Lu Chen only mastered the origin of thunder, but just like that, it was enough to deal with this thunder dragon phantom!

The Brontosaurus's body trembled violently, an aura that made it unable to have any thoughts of resisting at all.

After a while, all the thunder power in the thunder dragon's body was absorbed by the thunder wood, and the thunder dragon's body gradually blurred and dissipated in the air.

The Thunderwood Phantom continued to absorb the power of the purple thunder in the thunder pool.

An hour later, the remaining purple thunder liquid in the thunder pool was also absorbed by all the Thunder Fire Origin Seedlings.

At the same time, the seven Thunder Pattern Immortal Stones slammed almost at the same time, turning into countless fragments.

Lu Chen was overjoyed in his heart, these seven thunder pattern immortal stones were really extraordinary, and the thunder power contained in them could actually make half of the thunder pattern of the thunder origin seedling become a complete one.

With the addition of the previous thunder pattern, Lu Chen has two complete thunder patterns at this moment, which means that he has mastered the origin of thunder in two.

The entire Thunder Pond was shining, so Mu Lianqing and Peng Lao didn't see the scene of the Origin Thunder Wood Phantom and the Thunder Dragon fighting.

But now seeing the seven thunder pattern immortal stones shattered, it made the two old men's hearts tremble, and at this moment, the two of them really realized the strength of Lu Chen.

Lu Chen stood up, the thunder pool had already turned into a ruin at this moment, and there was no longer any thunder power in the hundreds of zhang around.

Lu Chen walked towards Mu Lianqing, the head of the Mu family, and Peng Lao, and hugged his fists at Mu Lianqing and said, "Senior Mu, these seven thunder pattern immortal stones are supreme treasures, but they were completely destroyed because of me, I'm really sorry!"

To Lu Chen's surprise, Mu Lianqing said with a smile, "Those who are destined for treasures get it, Lu Daoyou doesn't have to care!"

Lu Chen was able to pass the two levels under the Ancestor Dragon Shadow Saint Venerable one after another, which made Mu Lianqing look forward to it even more in his heart, whether Lu Chen could break through the third level, and whether he was really the destined person in the mouth of the ancestor.
