On the other side, the saber-toothed tiger tribe was jubilant after cleaning up the battlefield.

This was the first time they had defeated the Pterodactyl tribe in a head-on confrontation, and it was a big victory.

Only a few people were injured during the first round of arrow rain and put it in normal times, which is not even imaginable.

It's not that the saber-toothed tiger tribe is much weaker than them.

The fundamental reason is that the opponent is able to attack in the air, which is a complete dimensionality reduction blow to his own side.

If you want to fight back, you can only rely on some totems that are particularly strong, holding stones and throwing them into the sky.

Not to mention whether it can be thrown up, even if it can really be thrown, the accuracy cannot be guaranteed.

So the saber-toothed tiger tribe can be said to have been hung up and beaten all the time.

But fortunately, the two forces rarely have the opportunity to meet, so the chance of a real conflict is relatively small.

The sneak attack of the Pterodactyl Tribe sounded the alarm for Lin Hao, but it also brought Lin Hao two pieces of news that could be determined.

First, the Pterodactyl tribe had indeed taken refuge in the Tyrannosaurus Rex tribe, and one of the judgments was that the corpses of several of the enemies were easily recognizable, and the jagged teeth already indicated their identity.

Second, in this world, being able to seize air superiority is basically a declaration of victory, unless there are anti-aircraft weapons.

In Lin Hao's opinion, it was not too difficult to solve the problem of the air, because in the previous world, many cultivators could fly in the air.

Of course, although I can't fly, I can fly the brain - the flying machine.

However, the implementation of this plan is full of difficulties.

If Lin Hao was willing, he could take out some of the people alone to build some machines suitable for solo flight.

But the question in front of me is, even if it is really made, who will use it.

It's not as simple as aiming and pulling the trigger like a pistol, but it requires very complex control.

Counting on these primitive people to complete complex command operations, they didn't need the enemy to attack, and they fell from the air and fell to their deaths.

Lin Hao summoned the twelve sons over and wanted to discuss with them whether there was a new plan.

"Whatever you think, just say it, don't worry if it works. ”

In fact, Lin Hao didn't have much hope, after all, the twelve people in front of him were all taught by himself, and it was a bit difficult to think beyond this range.

The twelve people bowed their heads and pondered, and the scene fell silent for a while.

After a long time, Xiao Qi saw that the atmosphere was dull and took the lead in speaking.

"My lord, I don't know if I can do it. ”

Lin Hao nodded and motioned for her to continue.

"Can we domesticate some flying species like our enemies?"

After listening, Lin Hao shook his head.

If you use the same method against them, it will be very difficult to win.

Those tribes who have been with the birds and pterosaurs for hundreds of years, their level of understanding of these species is definitely not something that can be surpassed by their own side.

However, this suggestion gave Lin Hao a little inspiration, since the path of the Bird Tribe is not working, other roads can still be tried.

"Which arthropod tribe can resist insects?" Lin Hao looked at Xiao Eleven.

"My lord, there are many tribes that can resist insects, but none of these species are aggressive. Little Eleven thought for a while and said.

"Go back and prepare, and give me a list of the tribes that can resist insects in a moment, including their strengths and weaknesses, the chief's preferences, and the customs of the tribe. ”

In fact, Lin Hao didn't want to expect these insects to slaughter the birds and pterosaurs, the gap between species is not so easy to make up, even by numbers.

However, there are no absolutes in the world, and when a weak insect passes through his hands, maybe it will have the power not inferior to that of this bird?

Lin Hao already had a preliminary plan.

Two days later, Lin Hao took the list and thought about it, and the names of the two tribes came into his consideration.

One of them is the Iron Beetle Tribe.

The information is very detailed, and they can resist the iron beetle, relying on the totem and faith power of the two interconnected.

The insect was the size of a thumb and carried two heavy pieces of armor, and its flight speed was not among the best among arthropods, but it had no problem avoiding the bird's line of sight.

All the data are in line with Lin Hao's standards.

The only drawback is that their chieftain is not very good at his head, it is difficult to communicate with outsiders normally, and Xiao Qi has never been exposed to their language.

Another tribe that Lin Hao favored was the Firefly Tribe.

According to the data, this tribe is a kind of mosquito fly with a body length of less than four millimeters, which is good at flying and agile, and ordinary birds cannot catch them at all, and they have a very strong reproductive ability.

Moreover, the chiefs of this tribe are also different from ordinary arthropod chiefs, and are more inclined to the true beast tribe.

Lin Hao sighed, this tribe is good at everything, but the size of the insect is too small, and many of his operations can be difficult to implement.

But at the moment, there is no other way but to try both tribes, and let's talk about one if we can get one.

Lin Hao called the third and fifth children and whispered a few words to them.

Although the two were puzzled, they didn't say anything and turned to leave.

Xiao Qi was like a curious baby, lying on Lin Hao's shoulder, watching what he was drawing on the smooth wooden board.

After a long time, Lin Hao picked up the wooden board and checked it carefully before nodding with satisfaction.

"What is this? Why does it look so complicated? It's a new weapon?"

Xiao Qi looked at the pattern on the wooden board and felt dizzy.

Although she couldn't understand what was being painted, she could be sure that this was not an ordinary thing with Lin Hao's solemn treatment.

"It's a gadget that can't be handled. ”

Xiao Qi thought that Lin Hao was hiding from him, so he pretended to be angry and turned his head to ignore him.

"I really didn't lie to you, this is a set of clothes, but it's just a little smaller, so small that you can't handle it. ”

Xiao Qi tilted his head and peeked with his eyes, but after looking at it for a long time, he didn't find that the things on the drawings looked like clothes.

Two days later, Xiao Wu led two fifteen or sixteen-year-old primitives to find Lin Hao, who was still holding a convex lens ground from resin.

Xiao Wu was also very puzzled about what Lord Lin Hao was going to do.

"According to the drawings on the wooden board, make two more copies, and be sure to find a few ingenious ones, this thing will break when touched. ”

Xiao Wu took the drawing and looked at it carefully.

The structure of this thing is not particularly complicated, and if it is really to be completed, although it is a little difficult, it is not enough to deliberately select a few people from several tribes to complete it.

Suddenly, Xiao Wu glanced at the scale chart in the lower right corner of the drawing, and was stunned.

"My lord, this... It can't be done. ”

It's hard to imagine that this sentence came out of Xiao Wu's mouth.

In the past, he was excited every time he saw a new drawing, and he was never as overwhelmed as he is now.

This drawing only made him feel powerless.

"I know how difficult this is, so that's why I let you pick someone yourself. ”

"My lord, don't say it's them, it's me..."

Xiao Wu didn't say the rest of the words.

It's not that he wants to refuse, it's just that it's hard to get to the top.

Lin Hao patted Xiao Wu on the shoulder, and said with a smile: "It is said that you are the smartest of the twelve of you, why are you so stupid today?"

Xiao Wu looked at the drawing in his left hand in confusion, and then looked at the convex lens in his right hand.

Seeing that he still didn't understand, Lin Hao took both things over and put the convex lens on the drawing.

"Now you see, right?"

Xiao Wu looked at the convex lens in shock, and the powerlessness in his eyes gradually turned into a frenzy for discovering a new world.

Xiao Wu screamed excitedly, startling Lin Hao and Xiao Qi, and just wanted to make amends for the two of them, but Lin Hao directly invited them out.

"When I get back, I'll see the finished product!"

The first problem that plagued Lin Hao's heart was solved, and the rest was up to the third child.

I don't know what kind of surprise or scare this drug expert will bring to himself?

A few days later, the third child walked into Lin Hao's house dejectedly holding a pottery cup filled with liquid.

Lin Hao was taken aback, failed?

It shouldn't be.

If you do it your own way, you should be successful.

Did something go wrong?
