[Do you choose to establish a weapons research and development center?] 】

"Build!"

The weapons R&D center is not as big as he imagined, just a steel house covering an area of less than 100 square meters.

The weapon R&D center can be viewed inside, but it is somewhat similar to the scientific research center, and Chen Dong doesn't know much about these things, because there are no purchase items, so the R&D center is in a state of stopping.

The few scientific and technological research items that can be purchased are also surprisingly expensive, but if Chen Dong wants to build an army that can fight zombies head-on in the apocalypse, these things must be invested in research and development.

Mercenaries do tasks to upgrade the system, and systematically develop technology to train and arm mercenaries.

[Do you choose to build an arsenal? 】

"Build!"

This is a steel plant that looks to cover a relatively large area, and it can be seen from the name that the arsenal is supposed to be a place for the production of weapons and equipment, and the factory building is completely cordoned off.

Only the cargo compartment is open.

The daily power consumption of the science and technology center is 1,000 kilowatt-hours, which is not a large number, but the value of the power consumed by the arsenal is a bit exaggerated.

The fully operational arsenal consumes 10W kWh of electricity per day, a number that makes people's scalps tingle.

With today's power supply equipment, it is unrealistic to want the arsenal to run for a day.

[Decide to start a nanoweapon research program? 】

"Start!"

[The study will be completed after 48 hours]

I saw that the weapon research and development center, which had not moved at all, lit up and had already entered a working state.

[Current remaining upgrade value: 712.9W]

At present, there are only two automatic guards in the base, which is obviously not enough, after choosing a good location, Chen Dong purchased 28 automatic guards again, consuming a total of 140W upgrade value.

[Current Remaining Upgrade Value: 573W]

Just strengthened the fortress defense, there is not much of the remaining upgrade value, 500W can only provide a system upgrade, what makes Chen Dong even more troublesome is that the increase in upgrade value has begun to decline.

Without a reward, the mercenaries are clearly not very willing to accept mercenary tasks.

30 Auto Guards, if the fire is fully fired, the power consumption per second is 1800 kWh, and all the power is used for combat can only last 41 seconds.

Very short, it can be described as very short, 41 seconds for all power supply systems will be out of power, even if you use the 100,000 kilowatt-hours of electricity stored in the fortress, it will only last for 50 more seconds.

However, Chen Dong is not very clear about the power of the fort, and the combat effectiveness of the fortress cannot be estimated too high, but it cannot be evaluated too low.

Energy, energy is currently the most critical issue, the power supply system of the second level is no longer enough to provide the entire fortress operation, and if you want to free up new energy, you can only continue to upgrade the main system to unlock it.

"These guys aren't really going to attack here, are they?" frowned, he loved the troops, and he didn't know which side he would be on if there was a real war.

"Probably not...... Chen Dong was also a little hesitant, the tanks drove over, which was obviously a trend of Chen Dong going to fight if he didn't compromise.

The fortress government can not care, but the Ionic government has a mentality that it is determined to win.

"Listen to the people inside, immediately disarm and surrender!"

Hearing this, Chen Dong really almost burst out laughing, feeling that he was being treated as a prisoner, holding a firearm, trying to attack the army, and indeed breaking the law.

Chen Dong didn't plan to pay attention to these guys, just to test the ion layer, how exaggerated the attack of the ion layer can withstand, this must have accurate data.

The attack of bullets is completely negligible, and the only concern is whether the firing of small missiles and large-caliber shells will cause the ion layer to burst, and the ion layer rupture will need to consume more power to repair.

Theoretically, the energy is sufficient, and the fortress cannot be breached, but the repair of the ion layer has a short gap of a few seconds, which is a relatively large weakness.

"Captain, they don't seem to have any intention of coming out."

"Report directly to your superiors." Jiang Yun frowned, he didn't have any interest in coming here to fight, he was very dissatisfied with the government, what he wanted was not to shrink here.

He wanted to take weapons and take his people to the city to rescue more people, not to fight an unnecessary war here.

"Commander, the order to attack has been given."

"Attack...... hesitated for a moment, and through the telescope, he could see the entire structure of the fortress, and there were indeed some defensive equipment that he had never seen before, but this kind of defense Jiang Yun didn't pay attention to at all.

His regiment is a special operations regiment, and because of the special period, the equipment of the entire regiment is already the most advanced equipment in China.

"Commander?"

"Attack!"

The order to attack was given, all the troops were fully mobilized, and the easiest way to capture the fortress was to bomb the area, but the government could only choose to storm if it wanted to get the secrets inside the fortress.

Tanks are driving towards the intersection one after another, and ordinary bullets have no effect, which has been a theory for two days, whether it is a large-caliber sniper rifle or a single rocket launcher, it has no effect on the ion layer.

If a 125mm tank gun attack at close range is ineffective, a missile strike is a certainty, although the government does not want to go so far.

Chen Dong had already noticed such a big movement through the monitoring system, and his scalp was a little numb when he looked at a large number of modern main battle tanks, if the ion layer was really blown out, the continuous attacks would hit.

Rumble!

Salvo of main guns.

The shell hit directly above the ionic layer.

"It's okay......" breathed a sigh of relief, and the cannonball slid straight down, and the texture of the ion layer only fluctuated slightly, and did not crack.

"Commander, it doesn't work."

"See, what the hell is this? How is this possible with today's technology? Jiang Yun frowned, the main gun of the tank did not play any role, and the blue light curtain in front of him intercepted all attacks.

From what he had seen, this kind of defensive offensive was really beyond his common sense.

The 125mm tank main gun also uses armor-piercing shells, which are enough to penetrate the 1000mm armor, but it has no effect on the blue light curtain in front of him, clenching his palm, Jiang Yun is a little unsure whether it is a human being inside.

"Captain!"

"Ceasefire! Change the drill bomb! Since the armor-piercing bullet is ineffective, Jiang Yun wants to see if the light curtain can hold on under the action of force.
