"Immediately send a warning to the other safe zones, just say that the virus creatures are starting to attack the safe zone on a large scale, and let the whole safe zone immediately enter the security and prepare." Yao Ruyang also looked at the sound of guns and cannons outside at this time, and he immediately said to his adjutant, he would not think that the virus creatures would only attack a safe area in Guangshi, and they were likely to launch a full-scale attack.

Originally, other regular troops in the Southern Theater were carrying out the task of the life defense line at this time, and their task was to ensure that the life defense line was in the construction workers' safety zone, so they were not very worried, you must know that these troops were the second-line troops in Yao Ruyang's hands now, they were regular first-line troops, and they were all very well equipped, such as tanks, infantry fighting vehicles, armored transport vehicles, self-propelled artillery, self-propelled rocket artillery, etc., all of which they would not lack.

"Yes!" Adjutant Yao Ruyang immediately went down to inform the other security zones.

"Notice, all personnel are ready for battle, and the civilians are arranged to take refuge!" Li Cheng also received Yao Ruyang's warning from him, and immediately decided to temporarily close the commercial area and let Li Ke arrange for civilians to take refuge, otherwise, when the time comes, the virus creatures will attack, and they will not have any preparations, so they will be annoyed.

"The AH-6 gunship formation reported that they found a large number of mutant birds, and they are disengaging from the other side to fight, but the number of the other side is particularly large, let us prepare for air defense!" Li Wei also quickly walked into the command center, and quickly took out a report, which was the AH-6 gunship formation on patrol just now, which was directly attacked by mutant birds, if they didn't rely on their speed advantage, they would have directly left the battle, why not hit the other party, the reason is that there are too many opponents, and the M-134 rapid-fire machine guns they carry can indeed kill the other party, but if there are too many opponents, they have no choice.

"Air defense? Anti-aircraft artillery from where we came? "Li Cheng is also big-headed, he has always thought that the virus creatures have no air power, so what do they want for air defense, is it because they have a lot of money and no place to spend it, or they float on their own, and then Li Cheng now feels that why didn't he prepare some air defense weapons in the first place.

"Commander, the Sentinel Cannon has the ability to defend!" The red alert space reminded Li Cheng, because the sentry cannon has no firing angle restrictions, he is a turret that can rotate 360 without dead ends, so the sentry cannon also has a certain anti-air ability.

"Great, immediately order the engineers, activate the sentry cannon, and at the same time let all the Type 09 infantry chariots open the square for me, ready to shoot in the air, not to fight the plane, to hit the birds, I believe there is no problem! At the same time, the soldiers were ordered not to move outside so as not to be attacked! Li Cheng immediately asked the engineer to activate the sentry cannon, and at the same time, he also asked the Type 09 infantry chariots to drive to the square, using the 30mm cannon in their turret, they can also shoot birds.

"Let the civilians in the commercial area all hide in the basement, the doors and windows are completely sealed, and let the children in the base too, all of them will return to the dormitory for me, block the doors and windows, prohibit activities outside, and the soldiers will all enter the building and prepare to shoot in the air, but the premise is to protect yourself! The Type 99-A main battle tank was ordered to be modified immediately, with a control turret on it, and at the same time drive to the square. "When Li Cheng was building the commercial area, he had already thought about what to do if the commercial area was attacked on a large scale, so they all asked the house to build a basement to prevent any external situations.

"Pull all the AH-6 gunships outside to the underground warehouse!" Li Cheng looked at the AH-6 gunships on the airport, and immediately asked people to pull them back into the underground warehouse, he didn't want those damn birds to destroy these gunships.

"In the Red Alert space, sentry guns and machine gun forts will be installed in the commercial area immediately, and they will be installed on all sides, and every wall will be installed

12 machine gun forts and 6 sentry guns, calculate the resource consumption points instantly! Li Cheng thought about it for a while, and he was originally fighting in the commercial district

It can be regarded as an existence, but with the continuous expansion in the future, it is impossible for Li Cheng to give up the business area, sooner or later

Plus is in need of an increase.

"A total of 48 machine gun fortresses and 24 sentry guns need to be built, and a total of 720,000 resource points are consumed, and now the commander has zero remaining resource points!" The Red Alert Space reminded Li Cheng at one time, you have become a poor bastard again now, but Li Cheng does not regret anything, once the defense of the business district is strengthened, he will have a lot of peace of mind in the future.

"Prepare to meet the enemy!" Li Cheng glanced at the window outside and found that the two AH-6 helicopter gunships that had returned from the patrol quickly turned off their engines and were directly dragged into the underground warehouse, and even the pilots inside had not yet come down.

"Boom! Boom! Boom! Boom! "When the AH-6 helicopter gunship was dragged into the underground warehouse for less than twenty minutes, everyone saw the mutant birds in the distance, constantly making various screaming sounds, and directly pounced, and the sentry cannon on the wall was directly aimed at the direction of the other party, and it was launched immediately.

"Da! Da! Da! Da! "When the mutant birds quickly rushed down under the fire of the sentry guns, the firing port that had been hidden in the building was immediately powerful, and the soldiers inside were aiming at their own targets, and the guns in their hands were constantly spewing flames, whether it was a 5.56 caliber bullet or a 7.62 caliber bullet, they could easily tear apart the bodies of those mutant birds.

"If only there was *****, a spray would be a big piece!" A soldier quickly replaced the ammunition chain with the machine gun of the M-249 squad in his hand, and he couldn't help but sigh when he looked at the mutant birds that were still swooping down outside, because if he was *****, he would die if he sprayed it.

"Use air-burst bombs, don't hit your own people and buildings, understand?" A soldier quickly loaded the M4 recoilless gun, and a soldier next to him reminded him that this shell must not be aimed in the direction of his building, otherwise, it would easily cause accidental injury.
