Regarding which second-level main base to upgrade first, and what type of troops to come out first, Xiao Yu had been thinking about it for a long time.

People who have come from modern times understand modern warfare, and one of the most important links is naturally air supremacy. The Air Force is definitely king.

The four main bases, after being promoted to level 2, can summon the air force. At this time, it is a question of which air force is more suitable for the war of this era.

As we all know, the reason for the argument that there is air supremacy is based on the powerful aerial bombing capability of the Air Force. After World War I, for a period of time, many military scientists believed that as long as they controlled air supremacy, they could control the outcome of the war, and that large-scale bombing alone could completely destroy the opponent's will to resist, and there was no longer a need for infantry participation.

However, if the Air Force is not able to inflict mass damage and create a deterrent, then the Air Force can only be used as a scout.

During World War I and World War II, the reason why the air force was able to develop was because the carrying capacity of the aircraft continued to increase, and the heavy bombs that could be carried were more and more powerful, so that air supremacy could be realized.

And the air force of the four bases of Warcraft, although they can all fly, but there are very few that can cause mass destruction. How many bombs can a griffin, or a wyvern, carry? The Terran aircraft can only come out until the third-level base, but the obviously carrying capacity is not very high. And, the big problem is, there are no bombs in this world.

In this way, although on the surface, Xiao Yu has so many air arms that can be produced, but there are not many that are really useful.

Regarding the issue of bombs, Xiao Yu also thought about it for a long time, and finally found that only the self-detonating bats of the beast clan had two bombs: incendiary bottles and unstable compounds. If he wanted to research the bomb himself, he didn't think he had the ability, and the world wouldn't necessarily have these materials.

In addition, whether it is a bipedal wyvern, or a horned eagle, a fairy dragon, a griffin, or a dragon eagle, they can only inflict a single attack.

Such a single attack, when the opponent is not prepared, may be able to cause a surprise blow, but in a large-scale battlefield, it has no great effect.

In this era, there are giant crossbows, and Xiao Yu believes that the air force produced by the base cannot be so powerful, flying high enough for the other party to be unable to hit.

If you fly too high, you will definitely not be able to hit it down.

In this way, you fly down in mid-air to attack, and your field of vision is so wide, and other people's ballistas can easily kill you, which will not have much effect, but will only increase the huge losses.

Therefore, after thinking about it for a long time, Xiao Yu still decided to upgrade the base of the beast clan first, and then build a beast pen and send out the bats to bomb.

Xiao Yu was also very skeptical about the power of the bat's unstable compound and incendiary flasks, if it was a hoplite, he would be able to blow up such a thick heavy armor, but there was no way, now only they could bomb.

So, Xiao Yu immediately went to the base of the beast clan through a secret passage and began to upgrade the main base.

Xiao Yu knew that in the future, others would definitely know where these bases were, and they would definitely find a way to attack. Therefore, it is necessary to prepare both the base and the Lion King City, and the two places must be able to communicate and be able to switch forces at any time.

In order to guard the safety of several bases, Xiao Yu spent a lot of money to set up dense guard towers and watchtowers around the periphery of the three bases, and they were all second-level, there were a thousand of them, and they cost 1.5 million gold coins. If it weren't for Xiao Yu's gambling and winning eight million gold coins, he wouldn't have been able to build it at all.

The base is located in a very rugged terrain and dense jungle, and if an ordinary large-scale army wants to attack, it must pass through the jungle, so it will not form an array.

Once dispersed, these watchtowers can be of great use.

The watchtower is not as magical as in the game, and it also requires laborers and farmers to operate to be able to use it, but the watchtower can have the effect of finding enemies first, and there is a giant crossbow shot inside, as a means of defense, which is very good.

There were once adventurers who wanted to come here to capture orcs and elves to sell, but in the end they all hated the dense watchtower.

Xiao Yu originally wanted to rely on these watchtowers to defend the city, but found that the city head did not allow the construction of watchtowers. Moreover, if there is a place as big as a sentry tower, put a few ballistas or a dozen elven archers, and the power is not much different.

The watchtower is only in a place where there is no city, and after it is put down, it can play a great role, and where there is really a city, the strong walls of the city can be combined with heavy firepower such as ballistas. The watchtower is a bit redundant.

In the game, the watchtower is very powerful, but not in the real world, if the watchtower has the firepower of a machine gun, Xiao Yu will not hesitate to build a few rows of watchtowers under the city. But the sentry tower is just faster than the average ballista, and the defense of the sentry tower is definitely not as high as the thick city wall. In the previous games, the Watchtower was so powerful because it didn't have walls or crossbows.

Perhaps, after the tower reaches a higher level, it will be more powerful, and then it can be used according to the situation.

The upgrade of the base took three hours, which made Xiao Yu waiting there anxious, as if he went to only to find that all the pits were full of people.

Finally, after Xiao Yu was about to go crazy, the base of the beast clan reached level 2, and he could establish a beast pen and soul home.

Xiao Yu couldn't wait to immediately choose to build a beast pen, and let the laborers build five in one go. If it was just a beast pen, the speed of building troops would have been too slow, but now he urgently needed this group of air forces.

Reaching the rank of Master Chief, in addition to upgrading a main base, it also brought Xiao Yu's number of soldiers to 4,000.

Four thousand base soldiers, such a powerful class, if they cooperate well, they can do a lot.

Moreover, because he had upgraded the second-level main base, Xiao Yu found that the maximum number of catapults of the beast clan had been driven to fifty.

So, Xiao Yu immediately ordered to build another forty catapults, which was a very urgent need. It's really a relief in the snow.

With the extra 2,000 troops, Xiao Yu is also thinking about what kind of troops are better to produce. A thousand of them, for sure, are for bats.

If there is too little bombing, it will not be effective. It's a thousand people, and Xiao Yu still wonders if it's enough.

Another thousand, after thinking about it for a long time, Xiao Yu decided to produce some wolf cavalry, Kodo beasts, shamans, and witch doctors. The wolf cavalry is both mobile and absolutely tenacious, and can cause great damage, especially when facing the opposing cavalry.

When the horse sees the wolf mount, it will definitely panic, affecting the combat effectiveness of the cavalry.

Moreover, the wolves of the wolf cavalry can also attack, and it can be said that one class is equivalent to two attackers. It's like an elven hunter, but the wolf cavalry's combat ability is definitely much stronger than that of an elven hunter.

Elven hunters are mainly wandering, and they are strong in reconnaissance, and their melee attacks are certainly not as good as those of the tough wolf riders.

Xiao Yu also considered the human heavy cavalry, but the mobility of the heavy cavalry was not as good as that of the wolf cavalry. Now Xiao Yu's troops are still weak in the light cavalry, so it is still necessary to increase the wolf cavalry in the past.

Looking left and right, the first beast pen was finally established, and Xiao Yu couldn't wait to produce Batrider immediately. But when he took a look, he realized that if the four classes in the pen wanted to produce, they had to buy the production rights first.

To purchase the production rights of a class, you need 10,000 merit points.

Xiao Yu was so angry that his nose was crooked, and it was a restriction, couldn't he let me go smoothly? Directly build all the troops, and then sweep the world.

But fortunately, now that Xiao Yu has fought for such a long time, after buying five beast pens just now, there are still more than 50,000 merit points.

Xiao Yu did not hesitate to choose bats, wolf riders and Kodo beasts, and the remaining 20,000 merit points, Xiao Yu still had to build a soul home.

The Kodo Beast is something that increases the combat effectiveness of the Beast Clan, and it must not be less, but it doesn't need to produce too much, just get a hundred, and the wolf rider produces five hundred. Then there were three hundred shamans and one hundred witch doctors.

The five pens began to produce Batrider in full force, followed by Kodomon and Wolf Rider last.

It takes half an hour to produce a batknight, a pen can produce up to 48 in 24 hours, and five pens can produce up to 240, and a thousand bats can basically be produced in more than four days.

Xiao Yu built another soul home, bought a shaman, and only a few thousand merit points remained, and the witch doctor did not have merit points to buy for the time being. But anyway, there will be a war for these two days, and it will come out soon.

"Hmph, I now have a second-level base, just like you Xie Sanlang, fight with me, and see how Lao Tzu kills you." A gleam flashed in Xiao Yu's eyes.
