Chapter 2538 Immortal Thunder Cave

"Master, do you want to dig out the thunder stone?"

Lei Qilin asked.

"Yes, I must do something good and let the treasure see the light of day again!

Lu Chen nodded.

"I'm afraid this can't be done. The thunder stone is too big and connected to the mountain. Unless you move the entire Thunder Mountain, you won't be able to dig it out!"

Lei Qilin said.

"It is connected to the mountain. Is this a thunder stone or a thunder mountain?"

Lu Chen was stunned.

"There must be many lightning-inducing stones connected together in this fairy mountain. Otherwise, how could it attract fairy thunder and still hover on the top of the mountain for a long time."

Lei Qilin continued, "I just got under the floating soil and found that the lightning-inducing stone was not only huge, but also a closed stone door. The fairy thunder that was attracted came in through the cracks in the door."

"Under the floating soil, seal the stone door and draw thunder into the door?"

Lu Chen thought for a while and then said to Lei Qilin, "You come to protect me. The rookie is out of time. He wants to dig the soil with me. I want to open the closed stone door and see what treasures are inside?"

Lei Qilin immediately obeyed Lu Chen's instructions and spit out a thunder net to cover Lu Chen's head, blocking the fairy thunder coming from above for Lu Chen and freeing the rookie.

Then, Lu Chen and Rookie circulated their immortal energy, used both hands to suck up a large amount of floating soil from underneath, and threw it to the other side.

The two of them were busy for two hours, digging out a huge amount of floating soil, and dug to a depth of tens of thousands of meters, before they found the lightning-inducing stone that Lei Qilin was talking about!

Sure enough, the lightning-inducing stone was very huge and connected to the mountain, so it couldn't be dug out at all.

Moreover, that huge lightning-inducing stone was not natural at all. It had been built by someone, creating two huge stone doors!

Although the two stone doors are closed, they are not tight. There is a slight gap between the two doors. As long as the fairy thunder is attracted, the fairy thunder will be sucked in through the gap.

"The stone gate absorbs the immortal thunder. There must be something fishy inside, and there may be a big treasure!"

Lu Chen was overjoyed and without thinking too much, he directly stepped forward and opened the door.

"don't want!"

The rookie was so anxious that he quickly stretched out his hand to grab Lu Chen, and said, "This door is made of lightning-inducing stone, and it has absorbed immortal thunder over the years. The door body must contain a large amount of immortal thunder energy. You can't touch this door without refining the immortal thunder." Door."

"Oh, I didn't think about this problem for a moment, and I almost fell into it."

Lu Chen's hand almost touched the stone door. After hearing what the rookie said, he broke into a cold sweat on the spot.

"I'm not afraid of fairy thunder. Let me push the door open."

The rookie pushed Lu Chen behind him, then stepped forward and pushed it smoothly. The stone door did not open, but swayed slightly.

"Not enough power!"

Lu Chen reminded.

"Come again!"

The rookie opened the vision, and a bolt of lightning appeared from behind, shaking the space.

At that moment, the rookie's power soared rapidly, and his whole body was covered with immortal thunder, as if the god of thunder was born, bombarding all directions.

"Open it for me!"

The rookie used all his immortal energy and 100% of his strength to push the door open again.

Rumble…

The dusty stone door suddenly made a loud noise and began to loosen.

When the rookie saw that his strength was in place and the stone door was showing signs of opening, he immediately maintained 100% of his strength and pushed the door hard.

Boom boom boom boom…

The closed stone door was finally pushed open, and loud noises continued as the door opened.

After the stone door opened, Lu Chen finally saw a three-foot-wide passage inside, winding and spiraling into the ground.

However, that passage was made entirely of lightning-inducing stones, and it was filled with lightning. It was definitely not something that ordinary people could walk through!

Even an ordinary thunder spirit body can't walk away.

Only rookies and thunder unicorns who have refined the immortal thunder can walk in unscrupulously.

Lu Chen can do it too!

However, Lu Chen had to be protected by Lei Qilin all the way before he could walk in without being electrocuted by the immortal thunder.

The passage was full of fairy thunder, so Lei Qilin simply asked Lu Chen to ride up and carry Lu Chen into the passage.

Lei Qilin, on the other hand, activates the thunder absorption function and absorbs the fairy thunder throughout the process.

As long as there is a fairy thunder attacking Lu Chen, he will be sucked away by it immediately, making the fairy thunder unable to attack Lu Chen.

This winding passage filled with immortal thunders traveled about a hundred miles before reaching its end.

At the end is a huge underground cave, just inside the Xuanlei Mountain. There are more and more terrifying fairy thunders inside, making the entire underground cave like a cave of fairy thunder.

In the center of the underground cave, there is a thunder-inducing stone half a foot wide and three feet long, which is the core of this fairy thunder cave.

Because that lightning-inducing stone is purple-red, which is different from other lightning-inducing stones.

This is an extremely high-quality lightning-inducing stone, and all the fairy thunder in the entire cave revolves around it!

If this core lightning-inducing stone is removed, I am afraid that the fairy thunder in the entire cave will be out of control. What will happen then is unknown.

However, Lu Chen has no intention of poaching the core thunder stone for the time being, but wants to practice here.

Because the immortal energy in this Xianlei Cave is richer and purer, ten times that on the top of the mountain!

By cultivating here, more immortal essence will be transformed, filling the immortal essence pool will be faster, and your cultivation will be improved faster!

And this Xianlei Cave may be a remnant from ancient times, and it should be the training holy land of the Xuanlei Immortal Sect.

It's a pity that Xuanleixianmen has been here for too long and no outstanding talents have emerged, not even those who can reach the top of the mountain.

As a result, this holy land of cultivation was gradually buried in the world...

"Rookie, you and I will practice here. Xiao Lei will protect us and resist the interference of the immortal thunder."

Lu Chen gave an order, and Lei Qilin responded immediately.

Lei Qilin spit out a net of immortal thunder, covering Lu Chen and rookie, so that the surrounding immortal thunder could not attack.

With the protection of Lei Qilin, Lu Chen and rookie practiced with peace of mind and quickly entered into meditation.

One practiced the Nine Dragons Return to One Art, and the other practiced the Tiangang Void Art, both of which were the fastest ways to improve cultivation.

The immortal energy here is better, and the immortal essence converted from the immortal energy swallowed by the five dragon veins is much more than before, filling the eight immortal essence pools faster!

After only a few days, Lu Chen's eight immortal essence pools were filled, and he immediately rushed up.

Ka!

Breakthrough!

The peak of Xuanxian!

The immortal essence pools in the body doubled to sixteen, and the difficulty of improvement was also doubled.

Lu Chen didn't care about so much, and continued to concentrate on practicing. He would never give up until the sixteen immortal essence pools were filled!

After another five days of practice, Lu Chen's sixteen immortal essence pools were barely filled up with his desperate practice. Lu Chen didn't care about that and directly used all his immortal essence to impact the Earthly Immortal Realm.

Ka!

Another breakthrough!

The early stage of Earthly Immortal!

The immortal essence pools in the body changed again, doubling again to thirty-two!

In other words, the difficulty of upgrading is further increased, doubling again.

But Lu Chen is determined to reach the next level, and he will never give up until he reaches the middle stage of Earthly Immortal!
