"Oh? Could it be that you read from which book, but wasn't this dungeon discovered half a year ago?"

Edward, not far away, seemed to be interested when he heard the conversation between the two. "Boy, you must be bragging. When I was in the camp, I heard many people mention this city wall. Everyone who has seen it is impressed by it, but no one knows how high the city wall is, and there are even special bargains to bet on the height of this wall. Unfortunately, everyone still has their own opinions until now, and no one can come up with any decisive evidence."

"Uh, it's not very complicated to say. We all know that the position of the sun in the sky is constantly changing, but if it's not long, this change can be ignored. The light emitted from the sun can be basically regarded as a straight line." "The light falls on a non-transparent object and leaves a shadow on the ground. If you measure these objects and shadows, you will come to a very interesting conclusion that at the same time, no matter how big it is, any object has a fixed proportion to their shadows."

"I finally used this conclusion to calculate the height of this city wall."

"Wait, tell me again how did you do it?" Edward was confused when he heard it. What light, shadow, proportion... These things were really too trendy for the old thief.

"To be specific, I know my height and can also calculate the length of my shadow on the ground, so that I can get a proportional value. Then I measured the length of the shadow cast on the ground with my footsteps, and finally calculated the approximate height of the city."

"Is it that simple?" The old thief widened his eyes. Although he still didn't understand it very well, it did not prevent him from feeling unconsciously. Should he say that he is indeed a scholar? His head is full of these strange things.

The rookie beside him roughly understood the little follower's idea, but because of this, the girl couldn't help but show an even more surprised expression, "Do you even understand geometry?"

"Uh...it seems to be."

"Would you be a bit too foul?"

"No, I'm going to make a fire...I don't understand."

"Well, I'm increasingly justified now that you're just evading the responsibility of cooking."

Fortunately, Lolo was not too confused about this issue, and soon there was a new problem, "Was such a high wall, what is the giants living inside?"

It is not unreasonable for the girl to guess this. Not only is the wall outrageously high, but even the stone bricks used to build the wall are amazingly large. The width of a single stone brick is about two meters and the length is astonishingly six meters. No brick kiln can fire such huge stone bricks.

"Not the giants." Edward interrupted, "The giants are not as tall as the construction technology. Those guys cannot even build a pigpen well, let alone this majestic city wall. It is said that the houses in the inner city are close to the size of buildings on the ground, so the race to build this place should be similar to the size of our humans."

Rob stretched out a palm and pressed it on a stone brick. Although it had been baptized by time, the surface of the city wall was still flat and smooth. The gap between bricks was extremely small, and no plants could take root here. When the boy's fingers came into contact with the stone bricks, the great magician found that he suddenly lost contact with the magic elements around him.

Tsk, as recorded in the book, the walls of the dungeon can even block magic.

This is because a certain amount of mitril silver is mixed into every stone brick used to build a city.

At present, the best element isolation performance among all known materials is Mithril, but the reserves of Mithril have always been very rare, and the mitril veins are usually buried very deeply. No other race has effective exploration methods except dwarves. In fact, even in the dwarves world, Mithril is very rare. Dwarves craftsmen are very precious to Mithril, and they are only willing to use them when creating top-quality equipment.

This type of equipment is also called Demon-breaking equipment. In the Second Magic War, the Demon-breaking equipment was regarded as a trump card against human magicians. Unfortunately, because the production of Mithril is too small, this type of equipment is destined to be unable to be mass-produced.

If the irritable dwarf craftsmen see this wall, they will probably jump straight into their feet, and mix Misin with each brick. This is a very boring behavior. To build such a wall, the consumption of Misin will be an astronomical number.

Of course, the defensive effect obtained is also extremely terrifying.

Basically, spells below the forbidden spell have no effect on this city wall, and even if the ninth-level forbidden spell falls on this wall of forbidden demons, it has less than half the power.

In a sense, the existence of this wall is like a special purpose to restrain the profession of magicians.

But it has been less than a thousand years since the strange human mastery of magic, and this dungeon has been sleeping here for tens of thousands of years. Why did a civilized guy beware of the threat from tens of thousands of years later? This does not make sense in logic.

The future Super Magician Lord quickly overturned this conjecture. No, this wall is not used to deal with the magician. The reason is very simple - it is too high.

If it is really to deal with human mages, instead of building such high walls, it is better to use extra mitr silver to create more magic-breaking equipment, just like the dwarves did in the Second Magical War.

The Fireplace Castle is known as the steel fortress and is one of the most powerful cities in the Dawn Continent. It paid a heavy price to win over the human race there. But even the Fireplace Castle wall is less than 30 meters, which is far beyond the height of many siege equipment. The floating technique that magicians like to use the most can only make people twenty meters above the ground. With five hundred magic-destroying equipment, the battle was not ordinary hard.

Even if the floating turret, known as the ultimate weapon of humans, is included, the maximum height of this heavy weapon is only 100 meters. So if it is just to guard against the magician, there is no need to build a giant as high as 240 meters.

Seeing this magnificent high wall, the future Super Magician couldn't help but feel a little curious. What kind of enemy did the guys on the other side of the city wall face back then?

Hansen, as the captain of the team, was thinking about another aspect. The second-level swordsman looked up at the city wall and said regretfully, "It's a pity that I can't climb up, otherwise there would definitely be a lot of good things on it."

"Um?"

"The city generally has some heavy long-range weapons. If you can get one, you can make a lot of money by selling it to any force. Unfortunately, it is said that the stairs that climb the wall in the city have also been destroyed. The wall is too high, and no one can climb up now."
