The Princess of Northern Land

After Lin Ziyin entered, the frame sank quickly. Not only was she a little panicked, but Chu Suifeng and Si Jinhan standing next to her had expressionless faces.

In a short time, the wooden frame fell to the ground.

Lin Ziyin followed Chu Suifeng out of the house and was surprised when he saw the furnishings in the room clearly.

It turns out that this is a lower passage. The rock layer below is very thick and the space is very large. The surrounding walls are filled with large pearls, which illuminate the inside very brightly.

With a lot of money, Lin Ziyin once again looked back at the frame just now, sighing in his heart. There are indeed many talents in the Tianji Building. This era actually allowed him to see the most primitive "elevator".

"Follow me." Chu Suifeng saw her distracted and looked at her with a cold face to urge.

Lin Ziyin quickly quickened her pace to keep up with him. She was not familiar with this place, and she didn't want to risk her life here.

Si Jinhan saw her muscles tightening and knew that this girl was starting to worry about her life again. He couldn't help but grinned and walked side by side with her, "Don't wander around. There are too many traps here. If you step on them carefully, you will lose your life." "

I'm surprised you said that! Lin Ziyin did not dare to glare at him, and followed Chu Suifeng in front of him with lowered eyebrows. But Si Jinhan still caught the panic in her eyes.

Fun! Si Jinhan's bad temper broke out again, and his low laughter echoed in the basement for a long time.

Smiling like an idiot! Chu Suifeng rolled his eyes at him.

After turning around seven times and eight times, Chu Suifeng and Lin Ziyin finally stopped in an open area.

Lin Ziyin saw at a glance a group of people busy around a tall sling.

"My lord, the range is not enough."

"It's not particularly convenient to move around," someone said.

"Miss Lin, please." The old man looked at Lin Ziyin.

Lin Ziyin walked over quietly and carefully inspected each component.

As the saying goes, a connoisseur can tell when something is wrong. She, Lin Ziyin, designed the thing. Of course she is more familiar with these parts than the average person.

Upon inspection, she found many design flaws. In fact, she made a principled mistake.

Modern rubber bands used to launch ranges are special items, and the elasticity of the rubber bands is particularly good. However, the ancient "rubber bands" are from animals, and their elasticity cannot be compared with modern ones.

"It needs to be modified here." Lin Ziyin said to the few people gathered around, and then she made several reasonable suggestions.

Everyone was immediately enlightened after hearing her explanation. When she finished speaking, everyone looked at her with respect, and there was no trace of contempt on their faces.

"If you want the catapult to be more flexible, you need to install a wheel axle on the site." Lin Ziyin said the last sentence after hesitation.

She majored in mechanics and was a famous young professor in the military academy. If it weren't for her father's relationship, she should be one of the country's most important cutting-edge weapons researchers, so she couldn't say anything about weapons from ancient times to the present. She is familiar with the simple design and production. For her, it is actually something that can be easily grasped. To exaggerate, it is not a big deal for her to build a cannon or bomb here.

However, if her friendship with Chu Suifeng has not reached a certain level, or if she does not know Chu Suifeng very well as a person, she will never show her trump card.

The extra pointers given today can be regarded as giving Chu Suifeng face for the sake of his partners.

"Wonderful." Everyone was eye-opening when they saw the track-like structure, the adjustable range and the auxiliary axles. As expected, it was easier said than done. It turned out that although the ideas in the drawings were relatively clear, they were far from the shock that Lin Ziyin's live combination brought to them.
