"Can we swim down the river?"

While the others were still basking in the delicious taste of the barbecue, Allen looked at the dark surface of the river and his heart moved. Pen "Fun" Pavilion www.biquge.info

"Impossible, there is an iron net under the water, there are people guarding the shore twenty-four hours a day, and out of the hole, there is a waterfall outside, the drop is nearly a hundred steps, even those who are proficient in water cannot guarantee safety, and the most important thing is that you are out of the cave, and the valley outside is patrolled everywhere, even if all the problems can be solved, if you go up to the top of the cliffs around the valley, you will also get lost, at least for a short time, do not want to find the place you came from, by that time, the horse bandits have already found out that you have escaped. ”

Elton's words dispelled Alan's thoughts and forced him to rethink.

"Since it's an underground river, why does it feel like it's warm?"

Elvis slapped the river with his feet and asked Alan about his previous doubts. The temperature of this underground river is indeed much higher than that of ordinary groundwater, and everyone will have the same doubt.

"I guess there's probably underground lava upstream of the river or a hot spring infusion. ”

Alan voiced his guess.

"You're both wrong, we've lived here for a few years and are very familiar with the temperature of the river, it's not always warm, it's changing with the seasons, and when winter comes, the water gets cold. ”

Sean shook his head, rejecting Allen's speculation.

"You mean the river flows from the ground outside the Rift?"

Listening to Sean's words, Allen's heart moved again.

"I'm not sure, but I guess. ”

Seeing Allen's eyes sparkle as he looked at him, Sean had no confidence in his own inference.

"If it is an underground river, the temperature should be constant throughout the year, and now since the temperature of the river changes with the seasons and behaves obviously, it means that its upstream is above the ground, affected by the temperature of the ground, and we are not too far from the above ground here. ”

Elton took Sean's words and uttered his analysis, and it sounded reasonable.

"Elton's analysis makes sense, but where exactly does this river come from? By the way, I have a map of the Great Dragon Rift. ”

Alan suddenly remembered that when he left the ancient city of Aogu, Hollanster had given him a map of the Great Dragon Rift provided by Emperor Higg.

Thinking of this, Alan didn't care about eating meat and drinking, turned around and ran back to the cave, and the others could only run back with barbecue in their mouths.

As soon as he entered Elvis's cell, Alan couldn't wait to take out the thin sheepskin from his bosom that recorded the terrain near the Great Rift Valley of the Dragon, and flattened it on the ground, and then Alan knelt in front of the map, used a small illumination magic to illuminate the surface of the map, and then groped his fingers near a scar-shaped pattern in the center of the map, and his eyes began to search carefully.

"Alan, what is this doing?"

Sean, who followed up, looked at Allen's strange behavior with some puzzlement.

"This should be the topographic map of the Great Dragon Rift, and Alan is probably looking for this river. ”

Elton explained.

"It is impossible to record the river on a map. ”

Sean denied.

"It should be here. ”

Just when the three of them were puzzled, Allen's finger pressed a place on the map and said excitedly, and the other three people stopped arguing when they heard this, and they all gathered around and opened their eyes to see the location of Allen's finger.

Allen's hand refers to a thin curve on the map, as long as anyone who knows the common sense of the map understands, this thin curve represents a river, since the name of the river is not marked on the map, it means that it is a nameless river.

"Look!"

Alan's fingers moved slowly along the thin line, explaining as he went:

"This nameless river, which originates in the remnants of the Togolese hills, winds for hundreds of miles, flows to the west side of the Great Rift Valley of the Dragon, and then disappears. ”

Finally, Alan's finger stopped at the end of the thin line, which happened to be somewhere on the western edge of the Great Dragon Rift.

"Alan, you mean that the river in our cave is the nameless river on the map?"

Elvis looked at the curve representing the river on the map, and finally understood what Eren meant, and not only asked in surprise.

"Will there be other rivers?"

Elton asked, studying the rest of the map.

"This is the map of the Higg military, I have just read the entire map, if there is no major omission in this map, then there should be only one such river that has broken the record by flowing outside the Great Dragon Rift, so I think it is very likely that the two rivers are the same one. ”

Allen's finger drew a circle around the Dragon's Rift on the map, indicating that there was only one river on the map that met the conditions he had stated.

"I think what Alan said is very reasonable, the Higg military may not be very familiar with the terrain inside the Demon Dragon Rift, but in the past few years, they are absolutely familiar with the terrain around the Demon Dragon Rift, and if there are other rivers, they should not miss it. ”

Elton nodded, agreeing with Alan.

"If this river is really connected to the river on the map, as I thought, then I can use this river to bring all my people in, and then use the horse bandits to go out to receive food, and when the strength in the cave is empty, launch a surprise attack and wipe out Bols and Emaar in one fell swoop. ”

Since you can't go downstream, then go upstream.

Eren slammed the map with a punch, excited about his contrarian thinking.

"Alan, don't be too happy. ”

Elvis jumped out again and poured cold water on Alan.

"Why?"

"Why? Is it so easy to get in from the above-ground river to the underground river? Are all your people accustomed to water? Even if they are water-accustomed, God knows how far this river is underground, and even a turtle can be suffocated in it, let alone a person. Besides, even if your people are all fish and can swim in, but how can you Alan go out to deliver a message with a landlubber, don't tell you that relying on your own water magic, the situation in the underground river is complicated, and a torrent and a whirlpool may make you dizzy, let alone cast spells. ”

Elvis threw out several questions in one breath, and he pursed his lips, thinking that Allen's idea was pure fantasy.

"El, I know all the difficulties you mentioned, but it's better than attacking from the front. ”

Alan knows better than anyone else that he wants to send a team of hundreds of people here along the underground river, not only an adventure, but a little fatal, the environment in the underground river is complicated, the undercurrent is lurking, and they are not magicians like themselves, even if they can make a magic array to protect them, it is impossible to protect hundreds of people at the same time, unless they are divided into small batches, and a small batch is transported in.
