Critically Strikes A Miracle At The Beginning

"Ouch!"

Xiaokong called out sweetly, needless to say, he would definitely take Fei Ya to the pool for a swim.

In the evening, the channel was still warmed up as usual. Luo Yu and the team basically cleared the level without encountering any resistance.

In the room where the golden eggs were smashed, Fang Yumeng said with a chuckle, "Well, you have the best luck, you should come."

Luo Yu did his part, and in everyone's expectant eyes, the hammer smashed down.

"boom!"

The golden egg cracked and a scroll appeared.

[Squad Sharing Technology Scroll: Thermal Air Defense Technology]

"what!"

Fang Yumeng was pleasantly surprised: "This is the technology of air defense towers!"

Elina looked at the scroll, then looked at Luo Yu, and sighed, "You two humans... luck is good."

Everyone's eyes showed joy, and Luo Yu was overjoyed!

He wanted to build an air defense tower for a long time, but he didn't have a scroll. I didn't expect that this time the golden egg had a scroll!

Luo Yu said with a smile: "We don't sell this scroll, I'll use it now."

"Um!"

Everyone has no opinion. Although the auction will be held soon, this kind of precious shared technology cannot be sold.

Click to use, everyone has received a prompt to unlock the technology.

After going back to their respective houses, Luo Yu soaked in the bathtub, squeezed Xiao Jin's tiger's tail beside him lightly, and said with a smile, "Go and get me a glass of juice."

"Oh!"

Xiao Jin was about to get up when he suddenly remembered something and said, "Master, can you drink the wine you are brewing?"

"I want to taste it."

Luo Yu laughed and said, "I almost forgot if you didn't tell me. I'll take out the wine tomorrow."

"Go, get me the juice."

Xiao Jin smiled and nodded, while Luo Yu was researching the technology that was just unlocked.

There are many buildings in this thermal air defense technology tree. The cheaper ones include thermal javelin towers, thermal anti-air arrow towers, and high-level thermal light beam anti-air bombardment cannons.

The functions of javelins and arrows are similar to arrow towers, so they are not necessary.

The beam bombardment gun is too expensive, more expensive than the electric shock tower.

After studying for a while, Luo Yu finally decided to build [Thermal Condensation Projectile AA Defense Tower]

This thermal anti-aircraft tower does not need to consume wood as a raw material, but condenses thermal energy into fist-sized thermal bombs to bombard the sky.

The attack power is 10 points, which means that it can instantly kill creatures with less than 10 points of physique. It is not powerful, but the rate of fire is good.

Launched once in 1 second, the air-to-air range is 2 kilometers.

The range of 2 kilometers basically exceeds the limit of the airship's ascent, and the most important thing is that the cost is cheap.

[Thermal Condensation Projectile AA Defense Tower: Fire Stone Brick*500, Iron Ore*500, Copper Ore*500, Silver*5000]

This cost is not to mention the comparison of the electric shock tower, even compared with the arrow tower, it is very cheap.

Of course, being cheap will naturally have many disadvantages. For example, it consumes 10 heat energy each time it is launched, and the energy consumption is large.

Only against the air, not against the ground.

Also, this is a building, not a piece of furniture, and cannot crit.

Luo Yu wouldn't be willing to build this thing if he hadn't gotten 10 heat collection panels before.

"Let's make it tomorrow!"

Luo Yu thought so in her heart, took a bath and went to sleep.

After breakfast in the morning, Luo Yu walked to the east of the territory. The first thing he built was not an air defense tower, but a strike array.

After the territory has been strengthened several times, it has expanded a lot. The original strike array can no longer stick to the air wall, so it needs to be built again.

This is simple, the original entrance space is reduced, and a section of death corridor is built, and then two walls circle the new entrance and it is done.

Luo Yu is already familiar with this job.

Of course, this is not enough. Arrow towers need to be added on both sides of the newly created death corridor.

At present, there are 17w wood and 32w stone bricks in the territory, and it's done!

After one operation, the strike array was perfect again, and because of the addition of a corridor and two arrow towers, the defense will only be stronger than before!

Luo Yu clicked on the construction page and started building the condensed bullet anti-aircraft tower.

The enemy from the sky does not seem to have only one intersection on the land, and the entire eastern air wall is almost their attack range.

The horizontal defense in the east is about 7.5 kilometers, and the coverage radius of one air defense tower is 2 kilometers, which means that two air defense towers can basically cover the airspace in the east.

Just two firepower is definitely not enough, Luo Yu decided to arrange the anti-aircraft tower in the way of architecture and ladder configuration.

A row of four anti-aircraft towers was arranged at the extreme range of 2 kilometers from the eastern air wall, ensuring that once the air force of the other side entered the airspace, it would immediately be hit by firepower.

If the opponent wants to destroy their own air defense tower, they need to advance to the range of the arrow.

It's like being beaten all the way in vain.

This is much better than building directly next to an air wall.

The air defense tower of the second echelon can be built directly on the base wall. The base wall is about 3 kilometers away from the air defense tower of the first echelon. Once the opponent's air force is close to the base, the air defense tower on the base wall and the air defense tower of the first echelon It can form a cross-fire, causing continuous strikes against the enemy air force.

This is the architectural air defense echelon conceived by Luo Yu.

In other words, building eight anti-aircraft towers at this stage, plus the electric shock tower and so many arrow towers, should be able to let the enemy's air force return.

Moreover, it is also beneficial for the air defense towers of the first echelon to be built in the wild. In case the opponent breaks through the strike array, they will be attracted by the air defense towers during the impact and then dismantled.

This can slow down some enemy charges.

In the case of 5 electric shock towers firing a salvo every 5 seconds, as long as they can hinder the opponent for half a minute, they can kill dozens of attacking units of the opponent.

Do what he thinks, Luo Yu began to build anti-aircraft towers according to his own ideas.

On the grassland, a flash of light flashed before Luo Yu's eyes, and an air defense tower appeared in front of Luo Yu's eyes.

This anti-aircraft tower is also one meter high and made of stone. It looks like a small stone radar. The bowl-shaped center store is where the thermal energy condensate bomb is fired.

After a while, Luo Yu built all eight anti-aircraft towers, and the next step was to connect the energy pipes.

There are enough copper mines for now, and it's done when they are built.

However, for eight anti-aircraft towers, a salvo would consume 80 thermal energy, one shot per second, and 4800 thermal energy per minute.

In other words, even a full thermal energy storage tank can only support about 10 minutes.

In addition, the release of the arrow tower also needs to consume thermal energy, a thermal energy storage tank is definitely not enough, and another needs to be built.

Not only the thermal energy storage tank, it is better to build one more thunder energy storage station.
