Zhang Tieyi looked at all the officers who stood up, stretched out his hand and began to roll call, he ordered three officers to stay, and then said: "All the operators with odd numbers stay, and the rest will all withdraw with me!" ”

"Yes!"

After Zhang Tieyi gave the order, he didn't hesitate to take the rest of the people towards the exit of the boarding!

Soon, Zhang Tieyi and the others rode the Brutal Spider Tan, rushed out from the exit at the tail of the storm, and returned to the interior of Dragon City in concealment.

After Zhang Tieyi and the others left, the Storm poured out a burst of firepower, crippling the rest of the mechanical legs of the berserker in front of him, and then turned around and drove towards the berserker walking on the left.

Zhang Tieyi, who was sitting in the cab of Zhutan, had a very gloomy face.

There is only one weapon, and if you want to kill two, there is naturally only one way, and that is to die together!

Using the combined power of the Tempest and the nuclear mine, it is estimated that the entire D area cannot be saved.

The whole command room was very depressed, and everyone lowered their heads.

Time passes by second.

About half an hour later, a mushroom rose from the sky, and a huge shockwave swept away!

The whole spider was shocked!

Without any accidents, the Storm took the initiative to meet one of the Ragepers for a few minutes, pretending to be invincible and began to flee, and naturally the two Ragers chased after them, and when they were very close, the Storm suddenly reversed and rushed towards the two of them, activating a self-detonation and detonating a nuclear mine!

Pulled the two furious inside.

After the shaking ended, Zhang Tieyi's whole face seemed to be a little older, and he said in a low voice.

"Notice, raise the Dragon City from the second-level warning to the first-level warning!"

"Yes!"

"So where are we going?" The operator next to him asked hesitantly.

"Return to the temporary command center in C1 area." Zhang Tieyi said tiredly.

On the other side, the mechanical commander looked at the rising mushroom cloud and made a muffled electronic sound.

"It seems that we have underestimated the backbone of carbon-based civilizations, and with the greatest respect for ancient civilizations, we will drive high-level xenomorphs and completely erase them!"

"Yes!"

One of the brain robots turned around and left directly.

In the underground refuge area of the Military Academy in Area B of Longcheng, Wang Yao and other students gathered together and looked at the text reminder on the display screen.

"Level 2 Combat Alert, Continuous Medium ......"

Everyone's faces were heavy, this alarm had been going on for nearly half a month, and the explosions coming from outside were not less at all, but more intense.

That's when it happened!

Suddenly, there was a shaking of the underground dark area.

Everyone looked at each other and looked at each other.

Wang Suo and the other mentors' faces changed slightly, they knew very well that there was only one reason for this kind of shock wave, either the artificial intelligence machinery that attacked Dragon City used some kind of forbidden weapon, or Dragon City used tactical nuclear mines.

Of course, this is not good news in either way, and it only proves that the fighting situation is becoming more and more erosive.

Sure enough, in the midst of everyone's uneasiness, suddenly the text on the virtual reality screen suddenly changed.

"Hint: Dragon City has been changed from a Level 2 Battle Alert to a Level 1 Battle Alert, please be sure to hide in the designated area, and any commotion and unauthorized escape are prohibited."

.......

The new hints are constantly flashing and refreshing, which is very eye-catching.

Seeing the new prompt, Wang Yao's heart fluttered, she knew that the situation was not optimistic, but she didn't expect it to be worse than she imagined, after fighting for so long, the battle alert level did not fall, but increased, which showed that Longcheng's situation was getting worse and worse.

And the meaning of the first and second level alerts is very different!

It means that Dragon City may be attacked.

In the temporary command camp of Longcheng C1 District, Zhang Tieyi strode in, and the people who stayed behind greeted Zhang Tieyi with red eyes when they saw him.

"General Zhang Tieyi, ....... Storm"

"Don't be distracted, that's the honor of the Tempest, put all your energy on the battlefield, what's the situation now?"

"Except for the D6 area, the rest of the situation is fine! A large number of heavily armed troops have been sent to reinforce D6, and the last of the Berserkers will be intercepted. "Just as the officer was reporting.

Suddenly, a herald rushed in and reported in horror.

"A large number of alien races have emerged on the battlefield, and the defensive lines in various areas are in an emergency!"

Zhang Tieyi's breathing was a little unsmooth after hearing this, and he just wanted to speak!

With a loud roar, the entire temporary command camp shook violently!

Zhang Tieyi stumbled and almost fell, and the adjutant next to him hurriedly stretched out his hand to help Zhang Tieyi.

"General!"

"What's going on!" Zhang Tieyi shook off the adjutant who was holding him and asked angrily.

"We're looking for why!" The officer next to him hurriedly called up the Dragon's Eye, only to find that Dragon's Eye 3 had lost contact.

They reported in horror: "Dragon's Eye No. 3 has lost its signal. ”

"Switch me to Backup No. 2!" Zhang Tieyi decisively gave the order.

"Switching!"

"The switch is successful, there is unknown interference, and the optical imaging is being switched!"

"Imaging!"

Soon the virtual image appeared, and the faces of the officers present were dark, and they saw three Type IV xenomorphs more than 70 meters tall appearing in the isolation defense line of D1 and C1 areas, and the corpses were everywhere around, the defending troops were all wiped out, and the entire isolation defense line was blown down.

Even above their temporary underground command area was swept by the ultra-long-range firing of one of the Type IV xenomorphs.

Behind these three Type IV xenos, countless low-level xenos frantically poured into Area C1.

Zhang Tieyi's whole face was gloomy and he could drip water, how long has it been! Half an hour earlier, he had withdrawn from the C1 defensive line, and in the blink of an eye, he had all been wiped out.

Thinking of this, Zhang Tieyi's hands clenched into fists and gurgled.

"General, let's withdraw! The xenos will be killed in no time. The officer next to him reacted and hurriedly persuaded.

Zhang Tieyi let out a long breath, and his expression changed!

Eventually, he said, "Withdraw!" Withdraw to Area B and order the surrounding troops to hold them for the time being. ”

"Yes!" The officer next to him replied.

After giving the order, Zhang Tieyi led all the commanding officers present to the escape route, which had a high-speed military train to Area B.

Walking on the road, Zhang Tieyi's expression was constantly phantom, and he didn't know what he was thinking.

Suddenly, a strange color bloomed in his eyes, and he immediately quickened his pace.

After a long time, in the underground refuge area of the Supreme Military Academy in Longcheng, Zhang Tieyi strode in, and the students who were hiding here saw Lieutenant General Zhang Tieyi who walked in, and his eyes were confused, what were the people from the military department doing here at this time.

Zhang Tieyi walked towards the mecha combat class, because the army later trained its own drivers, the orthodox students of the school were not transferred at the first time.

Wang Suo looked at Zhang Tieyi coming over, and the old face couldn't help but shake his head.

At this time, Zhang Tieyi came to Wang Yao under the attention of everyone.

Suddenly, all the students around were in a commotion, and they looked at Zhang Tieyi suspiciously.

"Miss Wang Yao."

"General." Wang Yao replied in surprise.
