[Should I spend 100 technology points to exchange for an energy station?]

"Yes!"

Zhao Yu still has 400 technology points left, and plans to see what new buildings will be refreshed after the energy station is completed.

As a building rose from the ground, Zhao Yu finally saw three new building lists.

"Operation Research Institute, Defense Fortifications and Air Force Command..."

"It doesn't seem to be of much help to the battle situation for the time being..."

Zhao Yu took a closer look and found that the fortifications did not mention that they could create walls, fortresses, sentry towers and other facilities.

The air force commander can coordinate and mobilize the air force, but currently there are restrictions in Tiancheng, and he dare not use it casually.

After the last Combat Research Institute appeared, all the weapons and equipment in the previous building list were refreshed with new content.

"Stealth tank, light tank..."

Zhao Yu scratched his head, but it seemed to be of no use.

Stealth tanks are not really invisible, but can hide their body under radar, and their technological level does not exceed level zero.

He knew very well that this subsystem was not perfect yet and could only be exchanged for zero-level technology. He knew this when he traveled through time.

At present, Tiancheng is suspected of being an alien visitor, who is at least a late-stage first-class civilization or even a second-class civilization with a high probability.

It is estimated that it will be difficult to compete with the ability to divide bases based on subsystems.

"We'll talk about this later. Let's finish today's battle first..."

Zhao Yu quickly stood up and began to mobilize his troops.

This time, he only sent 2,000 troops. If he wanted to defeat the enemy's 10,000 troops, he had to do a lot.

There seems to be a huge disparity in combat power between the two sides, but it is not an ancient cold-weapon battle, where numbers are needed.

In modern warfare, if you are poor, you will be able to strike accurately, and if you are rich, you will be covered by firepower.

Zhao Yu thinks he is quite rich!

This time, he prepared the King of Land Warfare, a total of 1,000 tanks, 500 mortars of various types, and 50,000 rounds of artillery shells.

This equipment may not be worth mentioning at the level of war between the two countries, but right now it is just two cities fighting, and both sides are unable to use their air forces.

The Black Rock City scouts reported that the Han family dispatched ten tanks, thirty mortars, and more than a hundred machine guns this time.

It doesn’t look like much, but it’s actually quite a lot. After all, this is the heritage of the Han family.

In addition, it was very easy to build Black Rock City in the beginning. With Xu Jialu’s connections, the four major families in Black Rock City had basically never fought large-scale wars.

Even tanks and mortars were not used much back then.

The last time Zhao Yu defeated the Han family's thousand-man group, it was a reminder to them.

But no one cares, they all think that Black Rock City is very strong and the Han family is very strong.

The problem is, having weapons and equipment is nothing, only being able to play well.

Otherwise, in the past, countries used to train or conduct military exercises, wasn’t it just for actual combat?!

Zhao Yu had already finished preparations for the war. After receiving the news that the Han family was sending troops, two thousand soldiers also took action.

This time, he did not hide anything, but let the large army go out from the east gate and cross Zhaojiabao Avenue, so that everyone could see his strength.

Showing strength is conducive to the stability of the fort.

When Zhao Yu's troops drove tanks and multiple mortars through the avenue, the whole city was shocked.

"Fuck, tank..."

"So many cars!"

"Is our Zhaojiabao so strong?!"

"Is this strength comparable to Black Rock City?!"

"Hey, Black Rock City doesn't have so many tanks!"

Among the crowd, there were also many people from Black Rock City. When they saw the hundreds of tanks, their eyes lit up, and they felt that they had made the right choice this time when they came to Zhaojiabao.

Everyone held their chests high and looked proud.

But some people looked worried, fearing that Zhao Yu would fail.

In addition, there are also some outsiders, some of whom are spies from other forces.

Some came from nearby towns to inspect Zhaojiabao.

Seeing the thousands of tanks in Zhaojiabao, these spies were all shocked.

I believe that when they send the news back, all the major towns will be shocked.

……

Outside Blackstone City, three thousand regular troops took the lead, followed by the remaining eight thousand mercenaries.

Although the Han family plans to use these mercenaries to contribute, it is not yet time.

After the last failure, they finally learned some lessons and sent a large number of people as the vanguard to conduct investigations.

To prevent another situation like being touched within five kilometers of the camp.

"Haha, ten thousand people fighting, this is my first time to experience this kind of thing..."

"Who is not? We are very lucky to be able to participate in this battle..."

"Otherwise, how many people can there be in Zhaojiapu? We have more than 10,000 people here..."

"I heard that Zhaojiabao is very rich, and all kinds of weapons are new. I can grab them all when the time comes..."

The mercenaries were very relaxed and chatted with each other along the way. No one thought that this battle would be lost.

Everyone thinks this is a feast.

Not only can they participate in the war and have a bargaining chip in the future, but they can also carve up Zhaojiapu after the war is won.

In this way, after several hours of trekking, the troops from both sides were stationed more than ten kilometers apart.

In this battle, Zhao Yu did not intend to make a sneak attack. After all, it was a battle for peace and prosperity, and it needed to be won with dignity.

Information about the enemy has been clearly seen through unmanned reconnaissance aircraft.

The enemy has no weapons capable of causing heavy damage to tanks.

Therefore, Zhao Yu was very straightforward and gave the order to charge directly at the moment the enemy set up camp.

A thousand tanks can just crush them with dignity!

Of course, before the head-to-head confrontation, Zhao Yu used signal shielding equipment throughout the entire process.

Blind all enemy drones.

The reason why Han Jiajun knew they were here was simply because this area was blocked by signals.

"Whoosh~"

"Whoosh~"

"Whoosh~"

Tank after tank, roaring at full power, rushed towards the enemy's position.

When Han Jiajun spotted the tank through the telescope, the distance between the two sides was less than one thousand meters.

"Tanks, a group of tanks..."

"Oh my god..."

Han Jiajun's reconnaissance team collapsed on the spot and was frightened by this scene.

No one could have imagined that Zhao Yu had so many tanks.

"Are we fighting some big group?"

"How to fight?!"

When the head of the Han family learned the news, everyone was stunned.

He never expected that Zhao Yu would be so powerful.

A thousand tanks were taken out as soon as they were said to be taken out.

"Counterattack, counterattack, don't let them rush over!"

The head of the Han family gave orders in a panic.

Fortunately, most of the soldiers were not aware of the situation on the front line. After receiving the order, they hurriedly installed artillery and fired in the direction of the front line.

It’s no use!

There are many types of tanks in the base. The tank Zhao Yu selected this time is a heavy-armored tank, weighing nearly twenty tons. The armor is so thick that it cannot be destroyed by artillery.

"Peng~!"
