After the company made a judgment, the ship girls immediately went to the bottom of the mud pit and searched. Fortunately, it was winter, so the smell at the bottom of the mud pit was acceptable.

Just a few minutes later, the ship girls who entered the bottom of the pit found some valuable clues from the mud. "I remember you should have mastered magic, why don't you dig with magic?"

Watching the ship girls jump into your pit and dig various items with their hands, Hugo was puzzled and asked indecisively about the unwillingness to throw it up with a ball of frozen mud.

In fact, at the beginning, he also planned to dig things in this mud pit with the ship girls because he felt that watching the ship girls work style really did not match his previous education.

But when he found that he could not dig out the frozen ice cubes as hard as stones, he could only stand by the pit with a depressed feeling as he watched the girls work enthusiastically below.

"As I said before, safety first." As the interim commander of the ship girls, the company answered Hugo's questions. "If magic is used here, I'm worried that it may attract the attention of Sweden and Norwegian Ministry of Magic."

"At least from the fact that Zhisi can sense this nationwide, we have every reason to suspect that the Ministry of Magic of various countries has built a magic surveillance network that is not very sensitive but has a wide coverage in China."

"Ministry of countries may not pay attention to casting spells in most areas, but it is hard to say about key surveillance areas like this. Therefore, for security reasons, I think it is more appropriate for us to dig purely physically."

"And to be honest, the efficiency of our manual digging is no less than using magic." After the company finished speaking, he waved a piece of black ice in his hand and said. "And now we have discovered something far beyond our expectations."

Twenty minutes later, the ship girl finished her search for the mud pit and collected various items that could be filled with a gasoline barrel. Then they began to use small chisels, drills or climbs to remove the dirty ice wrapped around the items.

Soon, a lot of things were cleaned up. Some ordinary people who obviously did not know how to magic were thrown into it, such as various daily objects and weapons from the Middle Ages to the present of Pigs. Several of them should have the value of certain cultural relics. However, about 1/5 of them were identified because these things can clearly see the traces left by the magic world.

"These things are the objects of suspicion." After pointing to the pile of things that can be confirmed to be the magic world, Buru said to Hugo. "According to my identification, these things should be thrown into the pool 50 years ago. If there is no accident, these things should have a direct connection with the incident that year."

"What did you see from here?" Hugo asked in confusion. Because he saw that the things in front of him contained bones, metal fragments, broken gold jewelry and even broken wooden sticks, they looked like a lot of garbage with some history. Basically, it was impossible to tell where it was related to wizards and the magic world.

"Details, my admiral, the core is the details." He said in a brutal manner, taking out a half of the ox shoulder blades and pointing to the missing part. "If you look closely, you will find that the missing part of the ox shoulder blades were bitten off."

"It's nothing to be bitten by a wild beast to death - no, there should be no cows in this place." After being reminded by Buru, Hugo quickly saw something wrong from the scapula of the cow.

"And the tooth marks on it are not right, they don't look like ordinary beasts." After taking the bone that was washed away by the ship girl just now, Hugo quickly saw the problem.

"It looks familiar - wait, this tooth mark seems to be bitten by a large person."

"Yes, apart from this large tooth mark, the other things found on the scene also pointed to this point." Bullishly said, pointing to the pile of things that had just been discarded on the side as if they were garbage.

"Everything is bigger and looks like it's for large humanoid creatures like giants or trolls."

"This will match." Hugo snapped his fingers. "My grandfather's father said that what he saw was something like a hill moving around the lake. If it were these giant creatures, everything would make sense."

"Obviously, some well-equipped giant humanoid creatures appeared by the lake and were likely to die here." Looking at the large quagmire in front of him, Hugo probably guessed what might have happened here.

"And we think that the ones who were active here back then should be the trolls rather than the giants." The company said as it kicked the bones beside it. "

These bones are cut with sharp tools or traces left by teeth, proving that these things should be the food of the giant creatures back then, but all the bones on the scene are raw and there are no traces of being cooked. This is not like something that the giant did."

"Yes, you're right." After recalling some of the books about monsters and giants I've seen before, Hugo immediately understood the reason why the company made this judgment.

"Although the giants are barbaric, they are used to using fire. At the same time, they basically eat cooked food when eating, but the monsters usually eat raw food like wild animals. At least such well-equipped giants must eat cooked food."

"But why did a group of fully armed monsters appear in such a desolate place?" After looking at the pile of things on the ground, Hugo showed a thoughtful look. "And why did they die here in a battle?"

After confirming the specific identity of the creature who died here, Hugo and the others checked the information on all the valuable fragments present.

From the fragments of weapons and equipment on the ground, the people present found through careful inspection that almost all of these broken metals were fragments of various weapons and equipment made for these monsters, with traces of damage on them.

"If you look carefully, you will find that different scars are left in the gaps of these fragments. Some of them are melting due to the high-temperature flames, while others are directly cut open by some extremely powerful force."

After carefully checking each item, Buru got more information from the fragments. "This is obviously caused by magic, otherwise it would be impossible to leave such traces on these items mixed with trace amounts of magic metal."

"You know, the ability of the giant monsters to make their own weapons is very poor, and leather aprons and big-headed sticks are already the limit. Therefore, the equipment on them must be similar to those of the magical definition of wizards or fairies for them."

"So the group of fully armed monsters here back then should be mercenaries of a major force. Considering that this equipment is not cheap and the fragments we found come from at least eleven or two sets of different equipment, I think there are only a handful of forces that can do this in the past century."
