In a flash of lightning, Chu Chen walked through the dense forest and came to the land of thunder.

At this point, there are no trees in the dense forest, only bare ruins and broken walls, which look very desolate.

"This is it!"

Chu Chen's figure stopped, and in front of him was a cliff about 100 meters high, like a giant sword stuck straight into the ground, and the cliff was as smooth as a mirror, which looked very strange.

"Boom!"

Countless thunderbolts intertwined in the sky above the cliff, making a roaring thunder, like a world of thunder, the power of thunder spread down, and kept hitting a position in the middle of the cliff.

"There is, the entrance!" Chu Chen fixed his eyes, in the middle of the cliff, where the thunder bombarded, there was a thunder gate, from the outside world, you could see the thunder world inside the door, it seemed to lead to another world, exuding a strange temptation.

The thunder world above the cliff is getting smaller and smaller, as if all the thunder power has been injected into this thunder gate, and that thunder gate is getting smaller and smaller, and there is still one person high at this moment.

"This door seems to have to absorb a huge amount of thunder power to open, no wonder it takes so many years to open it once. Chu Chen didn't rush in, but continued to observe, "Xia Zhenxi said that in the past, the opening of the Lei Mansion did not have such a big momentum, and the entrance door could last for three days, but looking at the speed of dissipation of this door at this moment, it would be completely closed in half a day at most. ”

In this way, there is only one possibility, and this opening is not a natural opening. The inference in his mind became clearer and clearer, "but someone opened it in advance!"

Under the cliff, there was no one, but Chu Chen felt an inexplicable weirdness, and his intuition told him that when he entered the Lei Mansion this time, there would be a huge crisis.

Life and death at stake!

"Who the hell is Qingyulou or the mysterious head of the Xun family?Or are there other forces that I don't know?" Chu Chen thought for a while, but found that he had no clue, and finally raised his eyebrows, and the determination in his eyes became stronger and stronger.

"Since you have come, it is impossible to leave halfway!" Thinking of this, his figure flashed, and he rushed forward, and when he reached the bottom of the cliff, he jumped up.

Halfway up, a white cloud appeared, borrowed a little strength, and took off again, and after several consecutive times, he came to the place of Kaminarimon.

Tiyun's indulging method has been practiced by him to perfection!

With a flash of figure, Chu Chen entered the Thunder Gate.

The moment he entered, he only felt a majestic thunder power around his body, and he was just about to borrow the thunder power of Xiao Lei, but he found that this thunder power strangely did not cause him any damage.

"Strange?" Chu Chen felt that the situation was getting more and more weird, but he was suddenly taken aback by the scene in front of him.

After entering the Kaminarimon Gate, it is a world of thunder!

Above the sky, countless thunderbolts danced wildly, as if with the will of the gods, ready to punish the mortals below, and in the middle, there was a thunder vortex, which seemed to be the door of thunder that entered.

And below, there is a huge city!

At this moment, Chu Chen was standing at the city gate, looking at the three huge characters on the city gate, the dragon flying and the phoenix dancing, like iron drawing silver hooks.

"Thunder Spirit City!"

This city is several times larger than the Thunder Spirit City outside, and the overall structure is full of a simple and old atmosphere, which seems to have existed for thousands of years.

It's just that the buildings in the city are full of ruins and broken walls, and the sword marks are dense, and it seems that after a tragic battle.

The little thunder in the sea of knowledge was even more irritable, Chu Chen sensed it slightly, and found that the air in this place was filled with countless thunder attribute spiritual power, and ordinary people could not absorb and refine it for their own use at all.

"If it weren't for the person who cultivated the Thunder Attribute True Qi, wouldn't he be able to replenish it at all here?" Chu Chen's heart condensed, and he relaxed a little, he possessed the Northern Spiritual Skill, and he could devour all kinds of spiritual qi for his own use, which was considered an advantage.

"Goo, goo!" released Xiao Lei, the little guy immediately approached Chu Chen's face, licked it cutely, and then his whole body was excited, and a divine sense came out.

Chu Chen received a sense of it, and immediately understood, "You want me to go with you?"

"Goo!" Xiao Lei blinked his beautiful eyes, shouted a few times, flew in front, and led Chu Chen forward.

At a rapid speed, two figures streaked across the street, heading in one direction to the west of the city.

The figure stopped, Chu Chen looked at the building in front of him, it seemed to be a very ordinary courtyard, and looked at Xiao Lei suspiciously, "Are you going to take me here?"

"Goo!" Xiao Lei cocked his tail and jumped straight into the courtyard, Chu Chen was helpless, and followed in.

As soon as I arrived in the courtyard, I saw a delicate little flower growing in a clearing in the courtyard, which was blooming with bright bones, and on the bones, the power of thunder flickered.

Every time the thunder flashed in the air, the bones bloomed a little, and it seemed that it was about to open completely.

"Thunder Flower!" Chu Chen was overjoyed, he didn't expect to meet this thunder-attribute spirit creature here.

There are a lot of materials needed to refine the Battle Pill, and the materials required for different types of War Pills are completely different, and the Thunder Flower is the best spiritual object for Chu Chen to refine the Thunder Attribute Battle Pill!

Although it is a flower, it does not belong to the medicinal material, and the power of the thunder contained in it is too violent to be used for alchemy, but there are powerful people in ancient times who found another way to integrate it into the refining of the war pill, and the effect is extraordinary!

"With this Thunder Flower and a few more materials, I can try to refine a Battle Pill!" Chu Chen was in a good mood, with the Battle Pill, his strength would be able to increase again.

Patiently waiting for the flower bones to fully bloom, the thunder flowers picked at that time have the best effect.

The thunder roared several times in a row, Chu Chen's eyes froze, and he sensed that more people seemed to be coming in, and a sneer appeared on the corner of his mouth, "Don't you give up? ”

At this moment, the flowers of the Thunder Flower trembled three times in a row, and suddenly bloomed completely!

"It's now!" Chu Chen made a move in an instant, and the little thunder transformed into infinite thunder spiritual power, covering his hand, uprooting the thunder flower like lightning.

The thunder power in the flower was instantly struck, but it was completely absorbed by the small thunder in his hand.

"Goo!" Xiao Lei's figure reappeared, smashed his mouth, and made a cute expression, as if he was very disdainful of the power of thunder, and that looked like a proud child.

"Hehe, I know you're amazing!" Chu Chen touched Xiao Lei's head and looked at its expression, "Let's go." ”

"Goo!" Xiao Lei was reluctant to go, screamed, and suddenly struck out with a claw, and the little claw filled with the power of thunder gently slashed across the ground where the thunder flower was, and among the dust, something came out first.

Xiao Lei grabbed it out and handed it to Chu Chen as if he were offering a treasure.

When Chu Chen took a look, he found that it was a fist-sized stone, and there was also a trace of thunder flashing on it, which looked even richer than the thunder power on the thunder flower before.

"This is, Thunder Stone?" Chu Chen looked at it carefully, thought about the records of the classics in the treasure house, and said uncertainly for a while.

The Thunder Stone, the companion thing that may appear before the Thunder Flower is conceived for 10,000 years, is the part of the thunder attribute energy that overflows after the Thunder Flower absorbs the infinite power of thunder, and after a long time of gestation, there is a certain chance of appearing Thunder Attribute Treasure.

The thunder attribute divine weapons or magic weapons refined from them are infinitely powerful for martial artists who have comprehended the thunder attributes.

"Could it be that this place has existed for 10,000 years?In these 10,000 years, there hasn't been a single martial artist in the late stage of the Xia family who has comprehended the thunder attribute?Could it be that it is so difficult to comprehend the thunder attribute?" Chu Chen's eyes flashed with joy, and at the same time, he felt that something was wrong.

He hadn't encountered an enemy who had comprehended the thunder attribute until now, so he didn't know how perverted he was to be able to use the thunder attribute martial art in the Qi Refining Realm.

"No matter what, look for an opportunity first!" carefully received this thunder stone into the mustard seed bag, and then touched Xiao Lei's head, "I didn't expect you to be so sensitive to thunder attribute treasures, then next, it's up to you!"

"Goo!" Xiao Lei blinked, and with a slight sense, he led Chu Chen in another direction.

Chu Chen unfolded his body and followed closely behind it.

Along the way, he found that many people had already come in, and in order to avoid trouble, he simply used the trick of breathing, and quietly went all the way to find the treasure with a strong sense of Xiao Lei.

Two hours later, Chu Chen appeared on a street in the north of the city, walking slowly.

"This thunder mansion seems to be a city 10,000 years ago, for some reason it fell into this space, under the power of this abundant thunder for 10,000 years, it gave birth to some thunder attribute spiritual objects, although the number is not much, but they are all very high quality spiritual objects. ”

"Other than that, there are almost no other attribute spirit creatures. ”

Chu Chen searched all the way, and had already collected more than a dozen thunder-attribute spiritual objects, and the materials for refining the thunder-attribute Zhan Dan were enough, but the more the Zhan Dan, the better, so he followed Xiao Lei to the tall building in front of him.

"Time is short, search this place, and go open the inner mansion!" Thinking of this, he sped up his body and swept towards the largest building in the north of the city.

"City Lord's Mansion!"

Xiao Lei took Chu Chen and swept towards the backyard of the City Lord's Mansion with a clear goal, even if he occasionally saw a few low-quality spiritual objects along the way, one person and one dragon didn't care.

With a "whoosh", Chu Chen stopped in front of a stone wall.

"Is this the place?" Looking at the stone wall full of thunder in front of him, Chu Chen turned his head and asked Xiao Lei.

"Goo-goo!" Xiao Lei's eyes showed a look of longing, put on a pitiful expression, and looked at Chu Chen with watery eyes.

"Is there anything important to you here?" Chu Chen understood, carefully observing the thunder on the stone wall, "This seems to be a simple formation." ”

Chu Chen thought back to the various formations in Ou Zhiqing's refining inheritance, but none of them were similar to the formations in front of him, and he knew that he had encountered obstacles.

He simply stood in front of the stone wall, studied the formation on the stone wall, and he was always eager to learn about things that could improve his strength.

After a long time, a hint of joy appeared on his face.

"Fortunately, the person who arranged this formation doesn't seem to be good at the formation, but he just forcibly laid it out with a strong cultivation. ”

"Among them, there are flaws!"
