"Backpack?" In order to maintain the balance between the left and right sides of the raft, Catherine and Eva in the other direction did not dare to move. They could only watch the three girls and Panis approach the edge of the raft and looked downward. They couldn't help but ask in surprise: "What backpack?"

"It's just a backpack." Panis replied very seriously: "It's the kind of backpack that is carrying a big shoulder, and can hold a lot of things in it."

"Thank you very much, but I know what a backpack is." Catherine rolled her eyes and said, "I don't know, for example, why does a backpack appear here?"

"The problem is, I won't know what you don't know, either." Panis shrugged innocently, "Actually, I really want to know why a backpack appears there?"

"If the information I have read before is correct, it should be a tributary divided from the main river of the Naramiya River." Vivian said nothing wrong. As a tributary of the Naramiya River, the turbulent river water of the Selius River has been reduced by the giant lake. When the lake water flows out from the downstream, it has become quiet and soothing. Seeing Panis nodding to this, the mage girl continued: "In this case, if the owner of the backpack accidentally falls into the water in the upper reaches of the Selius River, the backpack is surrounded by the torrents. Until the Lake of End, the water flow rate decreases, the backpack finally lets it break away from the control of the torrents and sleeps at the bottom of the lake."

"Your guess is very likely." Panis nodded and said, "But obviously, you have overlooked a very important issue. Although the water flow of the Selius River is turbulent, it is almost impossible for objects to flow downstream. The Selius River and the upper reaches are too circumcised. Even looking at the map feels a bit complicated. The possibility of such a large backpack flowing downstream is not high." Panis shook his head and said, "So, I think it is unlikely that it is a package that rushed downstream."

"What if it was left many years ago?" Lina asked curiously: "For example, it was left since the Third Age, and there was no forbidden area for living things at that time. Although it was dangerous, no one had ever come in."

Panis looked at Lina with a very strange look and asked back, "What kind of backpack is soaked in water for at least three thousand years. Can it still maintain a relatively complete appearance? No matter what material the backpack is made of, it will be rotten into pieces after soaking for hundreds of years. It is impossible to be like this now."

"There is only one possibility." Catherine sighed and said, "It seems that my grandfather and the others chose the lake. Did you know in advance that you insisted on walking on the lake?"

"This is not. I don't know their route." Panis shook his head and said, "I don't have the expectation to find anything from the lake, but to be honest, I vaguely guessed something about their choice to pass through the lake."

"Why do you guess they would choose to pass the lake?" Catherine asked in confusion: "Did they leave any clues in the cave?"

"Uh, it's not impossible to understand this way." Panis said: "We judge that they stayed in the cave for three to four days. At the beginning, we thought they stayed for so many days to search nearby. But later, we found the consumed essence of wood. It proved that they used magic that sees the earth. This magic has a very good effect, especially the essence of wood as spell casting material. The spell effect is even more amazing. If you use this magic to observe the underground, you don't need to search for three or four days. There is no need for any effort."

"But it's true that they stayed for three or four days." Catherine said in a deep thought: "Then they must have spent these three or four days doing other things, such as... shipbuilding?"

"Yes, they may not have been to Casa, the country of the sea, nor may they be able to make Casa-style rafts. Then if they want to pass through the lake, they must make several small boats that can be used." Panis nodded and said, "Building a ship is much more laborious than building a raft. If you are not skilled, it is entirely possible to take three or four days."

"I said. Have you two got the point wrong?" Deely heard it for a long time, finally couldn't help it. She rolled her eyes and said, "You may have discussed here for a few hours, so you might as well go down and pick up your backpack and open it. Is it a package that the expedition team accidentally dropped by that time? Maybe you can open it and look at it. It's not much easier than you want to save trouble here?"

"You idiot." Panis said with a lip curl: "If you want to salvage it, you must first see the twisted soul-spoken routes under the water. Are you planning to let me go to the water before observing the route?"

"Are the wooden poles in your hand a decoration?" Deely growled: "You wouldn't add a hook to it and hook the backpack directly from the water?"

"You'd better stop talking, the idiot has no say." Panis pulled the pole out of the water, and the pole more than ten meters long stretched out and poked the scorpion tail lion, saying contemptuously: "Do you think if this is really the backpack left by Old Field and the others, after soaking in the water for decades, I'll hook it up from the water completely? I'm afraid I'll break it with a little force. Now it can remain intact. I should also thank this here for the downstream of Lake End. There is no too chaotic water flow, otherwise the backpack will no longer exist by undercurrent."

"Uh, I don't want to talk to you." Deere opened her mouth and found that what Panis said made sense. She could not refute it at all, so she could only lie on her front paws depressedly, muttering and starting to pretend that she didn't exist at all.

"Are you going down?" After discovering that Panis had bullied Deely, he stood up immediately. Catherine took out several waterproof bags and handed them over. While helping Panis sort out the waterproof leather jacket he just took out, he whispered: "Be careful. Even if your swimming skills are high, it is still not as flexible as you are underwater. It is not as simple as you imagined to avoid those twisted souls. Even if we can't get this clue, it doesn't matter. You should give priority to your safety. If it really doesn't work, come up. Don't do it randomly."

"I know." Panis smiled and patted the knight girl's head to comfort her: "I won't force myself impulsively, don't worry."

The intimate action made Catherine's face instantly dyed a red glow. The knight girl secretly glanced around and glared at Panis fiercely, revealing two rows of snow-white teeth as a threat. Amid the laughter of the other girls, Panis also looked embarrassed, poured a bottle of breath-holding potion, and jumped into the clear lake water like escape.
