"Do you see the shape of the mouth of the cave? Like what? ”

The Demon Tower Evil Monarch asked.

"Dragons?"

"Not bad! It's the dragon! And it's a black dragon! Therefore, the inner spiritual spring is called the black dragon spiritual spring. ”

"So, this is a spiritual spring born in the body of the black dragon?"

"That's pretty much it! The body of the black dragon turned into a mountain stone here, and after a long time, a spiritual spring has been born in the body. However, it's best not to go in, otherwise the fossil black dragon will wake up, and Benjun will be invincible. ”

Demon Tower Evil Monarch Road.

This is not the poisonous dragon that was nailed by the Zhenlong in Poison Dragon Mountain, but a black dragon that is completely unrestrained and uninjured, and its strength is definitely even more terrifying.

Otherwise, Honglu would not have been so stupid, staying so far away from the cave to collect the spiritual liquid for several days, and would have gone in and emptied the spiritual spring directly.

And in fact, even if there is no threat that this black dragon may awaken, there is an extremely terrifying sense of coercion in the cave at this moment, which is difficult for ordinary people to resist, so they naturally cannot enter.

"It's been so long, it shouldn't be a problem, right?"

Luo Qinglan was very bold, and wanted to go into the cave to collect the remaining spiritual springs.

Otherwise, if you harvest it drop by drop like a snail here, what year will it have to be received?

"You can give it a try."

The Demon Tower Evil Lord nodded.

After all, the history of this Black Dragon Spirit Spring is very long.

It is also the nourishment of the Black Dragon Spiritual Spring that makes this underground dark river that spreads throughout the underground of Biling City nourished by the aura, and then forms a lot of spiritual soil, giving birth to the Biling Fairy Grass.

For such a long time, the fossil black dragon has not woken up, could it be that at this time, there will be such luck?

Of course, the main reason is that he is confident that when the black dragon wakes up, he will retreat in time with the girl.

"Then go ahead."

Luo Qinglan greeted with a smile, and just after the Demon Tower Evil Monarch held up the fire spiritual power enchantment shield, the two stepped into the Black Dragon Cave side by side.

Due to the blockage of the fire spiritual power enchantment, the powerful sense of coercion in the cave had almost no impact on Luo Qinglan and the others at this moment, but it was not difficult to move an inch.

It's just that the black dragon is huge and stretches for thousands of kilometers.

Luo Qinglan originally thought that she needed to walk a long cave path to see the spiritual spring.

But in fact, about the location of the black dragon's heart, Luo Qinglan was on the stone wall of the cave, and saw a half-full spiritual spring the size of a basin, and at this moment, from that slightly damaged position, a drop of azure spiritual liquid was slowly overflowing.

The spiritual liquid flowed slowly to the ground along the stone wall of the cave, and finally accumulated in the stone crevices, slowly flowing outside the dragon's mouth, and flowed into the underground river drop by drop.

"It looks like a drop of blue tears."

Luo Qinglan said with a smile.

"Girl, hurry up and take it, it always feels wrong."

The Demon Tower Evil Monarch frowned.

In this black dragon cave, there is a strange and powerful sense of coercion from beginning to end, and I don't know if there will be any other dangers in the bottomless black depths.

"Okay."

Luo Qinglan nodded, and the Qiankun Treasure Vase suddenly appeared.

Under the surging spiritual power, the mouth of the Qiankun Treasure Bottle was surrounded by black mist, producing an extremely strong suction.

As a result, the azure spiritual spring water suddenly turned into a small azure water dragon and fell towards the Qiankun treasure bottle.

However, as the azure spiritual liquid gradually decreased, Luo Qinglan saw a purple streamer at the bottom of the spiritual spring.

When I looked closer, it was a small crystal that was crystal clear, like the shape of a purple tear.

Exudes a quaint and extraordinary mysterious atmosphere.
