It only took one night to move the progress bar in the backpack one square ahead.

This slot is enough to exchange for a new item.

The magnetic probe is not a clever invention in this era, but the one in her backpack has a utility that should not be underestimated.

The magnet used in ordinary times can only absorb a certain range of things, and the same is true of Sinan compass.

But this magnetic detector can detect everything on all planes within ten feet.

As long as you hold it horizontally or vertically, you will be able to detect the nearest metal object within ten feet of you.

After Ye Yun'er finished reading the instructions, she couldn't wait to exchange it out and try it again.

She rubbed the round Sinan-like thing in her hand for a while, and then checked it, feeling that it was not so heavy, as if she was holding a light mobile phone.

She tried to bring it in front of her, placing it side by side.

The pointer on it did not move.

She moved it down again, and it was still the same.

Move another two inches, and it's still the same......

When she reached her knees, looking at the magnetic detector that seemed to be a stinky stone without any spirituality, Ye Yun'er lost her patience in the end, thinking that this thing was just a waste that fooled people, so she threw it away and threw it out a foot away.

"Even the backpack lied to me, it's really infuriating!" Ye Yun'er pinched her waist, only to feel that she was on the verge of collapse.

There was a pounding sound of a heavy object hitting the ground, but along with this sound, there was another "buzzing" buzzing sound.

Ye Yun'er looked over in surprise.

But I saw that the poor magnetic detector lying flat on the ground was shaking the slender waist of the pointer like a wave, as if shouting frantically: "There is a problem over there, there is a problem over there......

Ye Yun'er was taken aback, and then rejoiced.

She hurriedly ran over and picked it up.

But as soon as the thing came out of the ground and was held in her hand, it seemed to be a stinky stone of wood again, and it did not move.

Ye Yun'er finally understood that the cat was in the bottom plane!

And the direction that the pointer points to is exactly where the accuracy of the cat lies.

She pressed her surprise and hurried towards the wall in that direction.

Coming to the wall, she tapped little by little on the uneven surface.

Eventually, she noticed that there was a small pebble at the very bottom that was loosening.

She eagerly moved the stone out of the way, revealing an iron knob inside!

Ye Yun'er's eyes lit up and she gasped.

There is no endless road, and she has finally found an exit!

And the moment she stretched out her hand towards the knob, she also secretly swore in her heart - when she got out, she must give a word of advice to those who want to harm her.

Not everyone is a soft persimmon that can be pinched whenever they want, at least, she is not!

The so-called revenge with straightforwardness, tooth for tooth, she must make that person pay the price she deserves!

It's the time of dawn.

When Ye Yun'er breathed in the fresh air outside again and saw the bright and warm sunlight, she felt like she was reborn after death.

This feeling was all too familiar to her.

She looked around, looking for Mu Yihan's figure.

Unfortunately, the person she wanted to see was not here, nor was it in her sight.

Seemingly, he has already left?

Ye Yun'er was slightly disappointed.

She still thought that if she couldn't be found, Mu Yihan would never leave here?

She planned to return the same way she came, but after thinking about it, she decided to sneak down the mountain from the dense forest.

After all, if it was really Mu Qingyuan who wanted to harm her, lest she escape, and ordered the people here to keep an eye on her, then wouldn't she be caught in the net if she blatantly walked out?

In order not to repeat the mistakes of the past, it is better for her to be cautious in everything.

But there is no path in the dense forest, and if you want to go smoothly, you have to take a lot of twists and turns.

Ye Yun'er walked for a long time, avoiding many thorns and dangers along the way, only to feel that this road was very difficult to walk.

She gritted her teeth and persevered, and finally saw a small path.

Her dark heart was a little clearer, thinking that she had finally found her way down the mountain.

She followed the trail all the way down.

As she walked, she faintly heard the sound of someone talking.

"Hurry up, these are the tasks that the king has ordered us to complete this month, if we can't complete them, your salary will have to be halved!"

Someone else wailed, "But this catapult is not easy to make?" We built one in half a month, and it was very good. ”

"It's all because you're lazy that the progress is so slow. If you had stepped up, this task would have been accomplished! The man rebuked unceremoniously.

"Heaven and earth conscience, we work overtime all day. It's just that we have to build these iron tools ourselves, and we have to install these mechanisms ourselves, and we have to experiment for a day or two, right? We're really working hard to serve the prince......"

"Don't talk nonsense, you guys are talking nonsense here, we have already hit the north!"

“……”

This series of conversations became clearer and clearer, and the more Ye Yun'er listened, the more frightened she became, and she hurriedly dodged to the side, and climbed onto a tree with lush foliage.

Gradually, she drew closer to the source of the sound, and finally, through a leaf, she could faintly see what was ahead.

But there is a group of people who are working hard, and next to them, there are dozens of catapults!

The bodies of these catapults are two people tall, and so are the barrels. It's no wonder that it took so much effort to make this.

Ye Yun'er thought secretly. I heard from them that these things were all caused by the king of the southwest, and they were intended to attack the north.

Rushing to control it so urgently, does it mean that the King of the Southwest will soon make a move to attack the Apocalypse Dynasty in the north?

Then, in the near future, Yunzhou and other places that they have managed to manage well will be ruined again, and the people will be miserable, and the people will be full of complaints......

Thinking of this, her eyebrows couldn't help frowning, and Xiu fist clenched unconsciously.

She didn't want that to happen!

Just as she was indignant and worried, the voice of the previous seeming overseer came from there, "Look at how quickly gunpowder is made in the house?" The king was very pleased with them. ”

The few people who were working to make the catapult were all silent, but there was a faint look of injustice on their faces.

They were probably thinking that the gunpowder thing was originally very easy to make, because the ingredients were ready-made, and they only needed to mix and match them in a certain proportion and then wrap them in the outer skin.

But their catapult looks easy on the outside, but the mechanism inside is very complicated, and there are few people here, no matter how you compare it, they feel that they are at a loss.

And the words of the overseer, when Ye Yun'er heard it, made her more and more frightened.

Are they making gunpowder?

It seems that the weapons on this side have been mastered to a certain extent.
