"Backpack?" In order to maintain the balance on the left and right sides of the raft, Catherine and Eva in the other direction did not dare to move, so they could only watch the three girls and Pannis come together to the edge of the raft and look down, and couldn't help but ask in surprise, "What backpack?"

"It's a backpack. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 Info" Pannis replied very seriously, "It's the kind of backpack that you can carry on your shoulders and be big, and you can carry a lot of things into it." ”

"Thank you so much, but I know what a backpack is. Catherine rolled her eyes and said, "Tell me I don't know, like why there are backpacks here?"

"The problem is, if you don't know, I won't know. Pannis shrugged innocently and said, "Actually, I also want to know, why is there a backpack there?"

"The Lake of the End, if I'm correct, is a tributary of the main channel of the Naramia River. Vivien was not wrong at all, as a tributary of the Nalamia, the turbulent waters of the Celeus River were tasseled here by the great lake, and by the time the water flowed downstream, it had changed from violent and turbulent to serene and soothing. Seeing Pannis's nod to this, the mage girl continued: "In this case, if the owner of the backpack accidentally dropped the backpack into the water in the upper reaches of the Selius River, the backpack was carried by the torrent all the way, until it reached the Lake of the End, and the speed of the current decreased, and finally let the backpack escape from the control of the torrent and sleep at the bottom of the lake. ”

"Your conjecture is quite likely. Pannis nodded: "But obviously, you have ignored a very important problem, although the water flow of the Selius River is turbulent, it is almost impossible for any object to flow downstream, the Celius River and the most upstream, the river is too winding, even just looking at the map feels a little complicated, and the possibility of such a large backpack going down the river without being blocked by the rocks on the bank is really not high." Pannis, however, shook his head and said, "Therefore, I think it is unlikely that it is a package washed down from the upstream." ”

"What if it was left many, many years ago?" Lina asked curiously, "For example, it was left from the Tertiary era, when there was no forbidden land for living beings, and although it was dangerous here, it was not that no one had ever entered. ”

Pannis looked at Lina with a very strange look and asked, "What kind of backpack can still maintain a relatively intact appearance after being soaked in water for at least three thousand years? No matter what material this backpack is made of, it will all rot into pieces after soaking for hundreds of years, and it is impossible to be like this." ”

"Then there's only one possibility. Catherine sighed and said, "It seems that my grandfather also chose the road of the lake, did you know in advance, so you insisted on walking on the lake?"

"Not really, I don't know their route. Pannis shook his head, "I didn't expect to find anything out of the lake, but to be honest, I had a vague guess about their choice to walk through the lake." ”

"Why do you think they chose the lake to pass through?" asked Catherine, puzzled, "Did they leave any clues in the cave?"

"Well, it's not impossible to understand it that way. "Let's judge that they stayed in the cave for three or four days, but at first, we thought they were searching the neighborhood for so many days," said Pannis. But then, we found the essence of wood that had been consumed, proving that they had used the magic of seeing through the earth. The effect of this magic is very good, especially when using the essence of wood as a spell casting material, and the effect of the spell is even more amazing, if you have observed the underground with this magic, there is no need to search for three or four days at all. ”

But it is a fact that they stayed for three or four days. Catherine groaned and said, "Then their three or four days must have been used for other things, such as ...... Shipbuilding?"

"Yes, they may not have been to Casa, the land of the sea, and they may not have been able to make Casa-style rafts, so if they want to cross the lake, they must build a few small boats that can be used. Pannis nodded, "Building a ship is much more laborious than building a raft, and if you are not skilled, it is entirely possible to spend three or four days." ”

"I mean, you two are getting the point wrong. After listening to it for a long time, Dilly finally couldn't help it, rolled his eyes and said, "You guys are discussing here for a few hours, why don't you just go down and pick up your backpack and open it." Could it be that the package accidentally dropped by the expedition team back then, maybe you can open it and take a look, no more than you want to save trouble here?"

"You idiot. Pannis pouted and said, "If you want to salvage it, you must first see the activity routes of those twisted souls under the water, are you going to let me go into the water to observe the routes later?"

"Is that the pole in your hand an ornament?" Dilly growled, "and you wouldn't put a hook on it and hook the backpack directly from the water?"

"You better stop talking, stupid people don't have a say. Pannis pulled the wooden pole out of the water, and the wooden pole more than ten meters long stretched out and stabbed the manticore, and said disdainfully: "Do you think that if this is really the backpack left by Old Field, after being soaked in the water for decades, I can still hook it up from the water completely? I'm afraid that if I hook it with a little force, it will break, and now it can remain intact, and I should be grateful that this is the downstream of the Lake of the End, and there is no too chaotic current, otherwise this backpack would not exist with the undercurrent alone." ”

"Uh, I don't want to talk to you. Dilly opened his mouth, and found that what Pannis said did have a point, and he could not refute it at all, so he could only lie on his two front paws in frustration, and began to pretend that he did not exist at all.

"Are you going down?" Catherine took out a few waterproof bags and handed them over, while helping Pannis sort out the waterproof leather jacket she had just taken out, she whispered: "Be careful, even if your swimming skills are high, you are still not as flexible as you are on the ground, and it is not as easy as you imagined to avoid those twisted souls, even if we can't get this clue, it doesn't matter, it's better to give priority to your safety, if you can't do it, come up, don't mess around." ”

"I see. With a smile, Pannis patted the knight girl's head to comfort: "I won't rush impulsively, don't worry." ”

Catherine's face was instantly dyed red by the affectionate gesture, and the knight girl sneaked a glance around and glared at Pannis fiercely, revealing two rows of snow-white teeth as a threat. Amid the snickering of the other girls, Pannis, too, looked embarrassed, poured a bottle of breath-holding potion, and jumped into the clear water of the lake. (To be continued.) )
