The underwater world is completely dark, but fortunately, Alan brought Sean's illumination magic array with him, so that he can see his environment clearly and not be touched by the protruding rocks around him. Pen fun and pavilion www.biquge.info

With the effect of the lighting magic array, Alan can clearly see that all the surrounding rocks of the water flow, and the underground river is not completely closed, but it is only a few dozen steps forward, and a space suddenly appears on the water surface, this discovery makes Alan very surprised, he surfaced, and found that there is a huge cave that is almost completely closed, but the air in the cave does not make people feel turbid when breathing, indicating that there may be some small holes in the hidden places around that lead to the outside world, according to Elton before, this is also a normal phenomenon, because the soil layer in the Great Dragon Rift Valley is originally loosely structured。

It seems that the cave where the horse bandits live outside is not the only one, and there are many more caves in this mountain.

Eren surfaced, unleashed a lighting spell, went ashore and walked around the cave, seeing the entire cave.

To his surprise, this lava cave was actually similar to the previous cave, there were some small holes in the rock wall around the big cave, Alan made some simple judgments according to the direction of the water flow, and several of the branch holes actually extended in the direction of the river, which shows that these caves are likely to be connected with the outside caves, even if they are not connected, then the distance between them may not be too far.

This discovery really surprised and delighted Allen, if there is really a passage between the two caves, then it will be of great help to his next plan, because he can use the underground river to send his own people to this lava cave in batches to assemble, and on the night of the raid, his own people can directly appear in the cave where the horse bandits are through the secret secret passage, and kill them by surprise, so that not only can they launch a surprise attack at the fastest speed, but also control the risk to the minimum, even if the operation fails, they can also withdraw to the cave and defend the danger, and then gradually withdraw from the underground river。

Alan didn't spend much time in the newly discovered lava caves, nor did he go deep into the small caves that might lead to the outside, because the most important thing at the moment was to get out of the underground river and get in touch with the outside, otherwise no amount of favorable terrain would help much on his own. So he only walked around the cave for a moment, thinking a little about how to use the cave for the rest of the action, and then jumped into the river again, and continued upstream along the underground river.

Along the way, they passed through several large and small caves, which made Alan more confident in his plan, and the more such caves, the less difficult it would be for them to enter from the outside along the underground river.

It took about three or four hours to stop and go, and the water suddenly became turbulent, and the terrain in front of him increased rapidly, which made it difficult for Allen to advance, and there was no more cave in the middle, he insisted on advancing underwater for another half hour or so, just when he thought that he could no longer climb out and was about to give up, suddenly the rapid current became smooth again, and soon a new space appeared above.

Alan excitedly floated out of the water and took a few big breaths of fresh air before he felt droplets of water drop on his face, and not just a drop.

"It's rain!"

Alan excitedly muttered to himself that the presence of rain meant that he had finally walked out of the underworld. However, he can't confirm whether he has walked out of the Great Rift Valley area.

At this time, the sky was overcast, and it was pitch black all around, Alan turned off the lighting magic array, worried that there were horse bandits around him, he quietly swam to the shore, and the place he touched was a piece of grass, it seemed that he had indeed come out of the Great Rift Valley of the Demon Dragon, otherwise there could not be so much grass, and Allen's hearing was now not disturbed by the sound of water, and he could clearly hear the sound of frogs coming from the bank of the river not far away.

To make sure that he had indeed come out, Alan walked some distance away from the riverbank, and soon saw a wood, and Alan used the levitation technique to fly to the top of a large tree, and looked into the distance, and it was pitch black all around, and he couldn't see anything. Alan Mo sent two lightning spells, in such a rainy night, even if there was lightning appeared, it would not be too noticeable, and then with the instant bright light of the lightning burst, he looked into the distance, and the dense woods under his feet were dense, and he did not see the unique cliffs in the Great Rift Valley as far as his vision could see, obviously he was not in a vegetated valley in the Great Rift Valley.

Eren landed from the end of the tree and let out a sigh of relief, all signs that he had indeed reached the outside of the Great Dragon Rift through the underground river.

Next, Alan found a hidden spot at the edge of the woods, and he untied a bag that he tied to his body, and poured out of the bag an oval, nail-sized green object, which was the seed that Fresnel had quietly given him.

Eren threw the seed to the ground, and then silently recited the magic spell of ten thousand trees growing in his heart.

Under the effect of the spell, the seed quickly took root and sprouted, and in an instant, it grew into a two-foot-tall flower, and at the top of the grass a grape-sized bud was born, and the bud soon bloomed into a flower, and the growth of the twin grass was complete.

In order to see the appearance of the flower clearly, Eren reactivated the lighting magic array, and what appeared in front of him was a purple trumpet-shaped flower, and two thin twin stamens poked out in the center of the flower, like the tentacles of insects, the stamens were trembling slightly, as if exploring something, and the trumpet-shaped flower was turning slightly.

Ellen was curious about the locatable flower, but didn't have time to do more research, so he took out the bottle with the strip of cloth written on it, and placed the bottle under the flower, covering it with a few leaves, and whenever the Fresnel found the twin grass, they would find the bottle hidden underneath, and get their information from the strip of cloth inside. Based on the location of the river on the map, it should be only a few dozen miles away from Fresnel's camp, and if they receive the news, it is estimated that it will take half a day to arrive.

Everything was ready, and Alan marked the neighborhood in case he couldn't find the tree the next time he came, before returning to the river and starting his journey back.

The return journey was extremely smooth, and Eren took the water separation circle and the lighting circle, as long as he used water control techniques to ensure that he would not crash into the raised rocks in the underground river under the turbulent current. So the way back was several times faster than when he came, and it only took an hour for Alan to feel that the river flow in it had slowed down, and Alan stopped lighting the magic array, and then surfaced, carefully observing the surrounding environment, which was the cave where the horse bandits' lair was located.
