Outside the strange plant forest, there is a lot of space, but the line of sight here is less than 100 meters, it seems even darker, and the dome is also higher, which will give people a feeling of oppression and mystery.

Since it is an underground world, it is understandable that this place is large, after all, we are only thousands of meters away from the place where we came down, and maybe we have not really entered the underground world at all.

The doctor went out to investigate for more than ten minutes and then returned, and we all looked at him.

"Just now I went thousands of meters deeper, and the terrain here is not all the same as here, very high and wide, but there will be some huge karst caves connected to it, and a small number of low-level spirit beasts will appear. ”

The doctor raised his finger and pointed to it, then pointed to the left and right sides respectively, and continued: "The terrain on the left and right sides is very open, and the plant forest we just came out of should be the same as we expected before, a huge ring, around that entrance, it can be said that after entering from the entrance, you can walk in that direction, and this is the current situation. ”

Lao Wang nodded slightly: "It seems that now you can only choose one direction to move forward temporarily, and then change the direction after you can't move forward, as long as you don't repeat, you should be able to continue to go deeper." ”

Li Dadi took out a compass, but unfortunately the thing has no effect here at all, and like the above, it is impossible to distinguish a direction in the underground, and the pointer rotates randomly.

"Don't look at it, it's useless, it's not the Earth here, there is no North and South Pole. Lao Wang glanced at Li Dadi and said.

Li Dadi grinned: "I know, I just want to see if there is an extremely strong magnetic field after seeing here, if there is, we can easily identify the direction to avoid repeating." ”

The shadow circled in the air, "I'll just come, I won't get lost." ”

"Well, go ahead and let Shadow lead the way, she's very sensitive to direction and has a great memory. "I agree.

"That's right, let's go ahead and see how wonderful this underground world really is. Lao Wang said with a smile.

Without too much delay in the same place, he followed the shadow all the way to the depths.

The ground here is different from the previous botanical forest, some of which are very hard rocks, high and low, and occasionally a strange plant can be seen in sight.

A few hundred meters later, a huge slug appeared in front of us, and before we could get forward, we had already taken care of it.

When I stepped forward, Shadow said with some disappointment: "This big insect should be a level 1 spirit beast, but unfortunately, the beast core has not been found." ”

"Hey, this big guy looks like a slime, a little disgusting. Li Dadi looked at the dead reptile curiously.

It looked sticky, and we didn't touch it, even if the spirit beast corpse here could be brought out intact, we weren't interested in it at all, it was really disgusting.

Along the way, we encountered a number of large slugs, these bugs are very slow, but they can attack from a distance, and when they attack, they will shoot a cloud of foul-smelling liquid at the target, although it does not pose any threat to us, but the smell is really bad and disgusting.

Speeding up and leaving the slug-infested area, we slowed down and breathed for air.

From the entrance to the bottom, this giant slug is also the only spirit beast we have encountered, it is true that it is a spirit beast, but they do not have any beast core.

Soon we came to the giant cave that the doctor had called before.

The entrance of the cave is very tall, directly connected to the 100-meter-high dome, and there are many fluorescent stones in this cave, which illuminates the space in the entire cave slightly, and you can clearly observe any position inside.

Shadow flew inside and took a turn, and then her voice came from inside: "Come in, everyone, there are a lot of beautiful little flowers here, they look very spiritual!"

We were all in good spirits and quickened our pace towards the cave.

The space inside the giant cave is very spacious, as if entering an indoor football field, surrounded by all kinds of strange stones, some translucent creatures lurking in the corners or strange stones, as if they don't care about our arrival at all.

"Come on, the bugs here don't move much, and there's no danger. ”

The voice of the shadow came, dispelling our concerns.

The location where the shadow is located is on the wall on the right side of the cave, where there is a small waterhole surrounded by fluorescent stones, and the strange flowers and plants that the shadow said are growing around the small waterhole, and the colors are very bright.

The waterhole is not large, and the water inside is dripping and gathering from the stalactites on the side, and the surrounding fluorescent stones are beautiful.

"It's really beautiful to look at. I exclaimed.

Li Dadi stepped forward quickly, looked down, and suddenly exclaimed in a low voice: "Many, many colorful spirit chrysanthemums!

I'm dumbfounded, I basically don't know anything about these messy spirit herb elixirs, although Lao Wang knows some, but he doesn't know much more than I know, he doesn't have much research on these, and among us, Li Dadi knows a lot about spirit grass elixirs.

Wang: "What's that?"

"Colorful Lingju!" Li Dadi rubbed his hands excitedly: "I have only seen it in ancient books before, I didn't expect to see it here today, and there are so many at one time!"

"What's the use of saying it's useless?" I glared.

"The Colorful Spirit Chrysanthemum can help cultivators weaken the bottlenecks and barriers they encounter when breaking through, and can make cultivators break through more easily and step into a higher level more easily. Li Dadi explained.

"Uh...... Really?"

Lao Wang and I expressed our shock.

When a cultivator breaks through, he not only needs perfect preparation, but also a suitable environment, all because there is a barrier when breaking through some important realms, which is the so-called bottleneck.

If you want to break through your cultivation to reach a higher level, you must break through the bottleneck of cultivation, so that you can enter a new cultivation realm, so as to obtain a deeper cultivation realm and gain stronger strength.

However, the breakthrough of the bottleneck is not an easy task, and it is necessary to be fully prepared before the breakthrough time comes, if the preparation is not thorough, it is likely to fail, and once the breakthrough fails, it is likely to cause a significant decline in the strength realm, and may even suffer a very serious backlash to cause heavy damage to itself.

There are many reasons that can lead to failure, such as the lack of heaven and earth aura, being disturbed by others, and being unstable, but before that, cultivators will generally break through in a full state, that is to say, they have reached a critical point, but there is a bottleneck of cultivation stuck in front of them, which is a threshold, and it takes enough strength to support it.
