[Requirements: Skeleton*1 unit (2 units), Soul Energy*50 units...]

This type of fighter is not intended for use on the battlefield, but is more suitable for use on the territory, acting as a defender.

Although it cannot be placed on the battlefield, it is very good to place it in places like mobile fortresses, which is equivalent to adding a layer of protection.

Well, this stuff can be prepared for Zhang Peng and Liu Xingxing, or it can be sold to indigenous people like the Orc Empire. Both are good choices.

【Little Falcon Fighter】

【Category: Mechanical Engineering】

[Type: Fighter·Flybird Class]

[Introduction: A very ferocious small melee fighter, 20cm long, with an eagle-like beak and sharp claws, and its wings are made of blades. PS: Suitable for accompanying its master in battle. Who would pay attention to a small bird?]

[Requirements: Skeleton*1 unit (5 units), Alloy Metal Sheet*1 piece, Soul Energy*100 units...]

Similar to the Shrike, the Falcon is also a protective fighter.

The difference is that the Shrike Butcher Fighter has the prerequisite item Shrike Tree, which is basically fixed in one place, defending a fixed range and is not suitable for movement.

But the Little Falcon fighter jet follows its master, acting as a personal bodyguard.

Don't be fooled by this guy's small size. He is almost fully armed. From head to toe, he is covered with weapons. It is also a close combat model. There is really no problem using it as a guard.

The last one is the Tit Fighter.

【Tit Fighter】

【Type: Mechanical】

[Type: Fighter·Flybird Class]

[Introduction: A type of fighter used to attack shields. They are equipped with special beaks that have the ability to break magic and have a special damage effect on shields. However, their size is too small, so it is difficult to destroy large shields. PS: If you plan to use them to destroy fortress-level shields, you must prepare a large number of them.]

[Requirements: Skeleton *1 unit (3 units), Soul Energy *30 units, Magic Metal *2 units...]

How to say it, the Tit fighter is useful, but also useless. After all, as mentioned in the introduction, it is very difficult to destroy a large protective shield, and it requires a huge number of Tit fighters to do it.

To be honest, the Titmouse fighter is probably more suitable for destroying the magician's single-body protective shield.

It can also play a certain role on the battlefield.

Li Ziyu didn't plan to make too many. He would just make some for Liu Xingxing and sell some to Sun Lei.

The reason why it was given to Liu Xingxing was because some ancient ruins had protective shields, and Liu Xingxing was very troubled by such protective shields and often complained to him that he saw good things but could not take them out because of the protective shields.

Giving him a batch of Chickadee fighters should be able to alleviate this situation.

Up to now, Li Ziyu feels that his research speed is still acceptable, but the level of the fighter planes he has developed is relatively low. They are probably all fortress-level and have not reached the castle level at all.

Whether it's the insect-class bee-type or the bird-class fighter, it seems that their main targets are still fortress-class. They are probably useless against castle-class ones.

But Li Ziyu was not in a hurry. With more and more technology, powerful weapons would always appear.

As for these fortress-level ones, there is no need to waste them, they can always be sold.

Sun Lei has already said that he will collect them, and the time travelers from the Wasteland Alliance can also send out a batch.

Although Batubu and they have been promoted to the castle level, others have not and are still at the fortress level, so they can still use the things they have researched.

If worst comes to worst, Zhang Peng can resell it through the system.

It’s hard to say how much profit you can make, but it shouldn’t be difficult to recover the research costs.
