Luna did not respond to Han Feng's half-joking words, but said seriously: "Tell Team Han that you need to accept the task issued by the system. After passing the task, you can build the time machine."

"Okay!" Han Feng nodded solemnly and continued: "Accept the system task!!!"

When he said this, Han Feng was mentally prepared... because he knew that what Luna had to complete next would be as difficult as climbing to the sky!

You should know that the time machine is different from other super weapons in the Red Alert game. It does not belong to the encounter mode or the custom mode.

There were only buildings in the mission, and Han Feng only glanced at them in a hurry...

"Report to the Korean team, the system has hidden tasks, you can only accept one. Task 1: Nuclear bomb silo. Task 2: Weather control device. Task 3: Iron Curtain device. Task 4: Time and space teleporter. Task 5: Gene

Mutant. Mission 6: Time Machine."

After Luna finished speaking, Han Feng didn't even think about it and said directly: "Take the mission of the time machine!"

"Okay Team Korea, you have accepted the hidden mission six issued by the system - the time machine."

After Luna said this, the system's mechanical sound sounded: "Hidden mission six, difficulty: hell level. Chance of passing: extremely low."

"When the commander completes the following tasks, he can build the ultimate building-the time machine."

"Task 1: Upgrade all main buildings to full level status."

"Mission 2: Unknown (when the commander completes mission 1, mission 2 will be unlocked)"

Before Han Feng could react, the system's mechanical sound disappeared...

"Hell level... extremely low pass rate..."

At this moment, Han Feng's mind was filled with these two sentences...

A few seconds later, Han Feng, who was slightly awake, slowly clenched his fists.

"No matter what...I built the time machine!!!"

After talking to himself, Han Feng asked Luna in his mind: "Luna, how many main buildings are there that have not been upgraded to three stars?!"

"Report to the Korean team. Among the main buildings, the base is rated two stars. The remaining heavy factories, power stations, and ore refineries are all rated one star."

"..." After listening, Han Feng continued to ask: "How many gold coins do you need to upgrade to three stars?"

"Report to the Korean team that a total of 3.4 million is needed to upgrade all main buildings to three stars."

As soon as Luna finished speaking, Han Feng immediately turned his attention to the system.

Staring at the amount of less than one million in the gold coin column, Han Feng said: "There are still two and a half million... almost, almost..."

"Luna, where are the zombies now?"

That's right... for gold coins, Han Feng targeted the zombies not far away...

"Report to the Korean team that the zombie wave has stopped eight kilometers away from the zinc mine."

"Okay!!!" After hearing this, Han Feng was about to leave to "withdraw money."

But as soon as he took a few steps, Han Feng was stunned...

In his mind, Han Feng remembered the mysterious girl asking him to return to the defense base...

"this……"

Looking into the distance, Han Feng hesitated...

On one side, there are a large number of gold coins waiting for him to collect. On the other side, there are "ethereal" threats and constraints.

How about... let Natasha guard the base for him? Suddenly, this idea popped into Han Feng's mind.

But the next second, Han Feng shook his head...

Now that Natasha has no weapons of her own, in terms of combat effectiveness, a level 4 zombie can make Natasha "drink a pot".

Overruled Natasha

After thinking about guarding the base, Han Feng looked at the Kongzhi Department...

Staring at the two Invader fighter jets on the apron of the Air Command, Han Feng asked: "Luna... what are the weapons of the Invader fighter jets?"

"Reporting to the Korean team, there are two types of weapon configurations for the Intruder fighter planes. The first is the "young animal" - the Maverick air-to-ground missile (note: only one missile can be launched per attack). The other is

, are five free-fall or slow-fall bombs of 453.6 kilograms (total weight)."

"Oh~ five bombs, right~" Han Feng raised his eyebrows and squinted his eyes.

At this moment, Han Feng already had new ideas in his mind.

"Luna, replace these two fighter planes with slow-dropping bombs!"

"Report to the Korean team that the Intruder fighter plane is missing one set of slow-drop bombs."

After Luna finished speaking, Han Feng remembered that he was "impatient" and insisted on watching the attack demonstration of the fighter planes. As a result, one fighter plane now has no ammunition...

After a pause, Han Feng found a solution and said: "No ammunition? Then let the barracks make it?"

"Report to the Korean team that the barracks cannot produce ammunition other than individual weapons."

"..."

"Luna, upgrade the heavy factory..."

At this time, Han Feng also realized that the barracks only produced and manufactured weapons for soldiers. In other words, after the heavy factory is upgraded, can it also manufacture weapons for vehicle fighters?

"Report to the Korean team that it will cost 300,000 gold coins to upgrade the one-star physical building - Heavy Factory to a two-star one. Please confirm the upgrade."

"Confirm upgrade."

"Okay, Korean team, the one-star physical building - the heavy factory is being upgraded, please wait..."

A few seconds later, Luna continued: "Reporting to the Korean team, the one-star physical building - Heavy Factory has been successfully upgraded to a two-star rating."

"Okay, continue upgrading." Just now, Han Feng saw that he still had more than 600,000 gold coins left. The main building had to be upgraded anyway, but it was only a matter of time. In this case, it is better to upgrade now.

"Report to the Korean team that upgrading the two-star physical building - Heavy Factory to a three-star level requires half a million gold coins. Please confirm the upgrade."

"Confirm upgrade."

"Okay, Korean team, the two-star physical building - the heavy factory is being upgraded, please wait."

After a few more seconds, Luna continued: "Report to the Korean team that the two-star physical building - Heavy Factory has been successfully upgraded to a three-star rating."

"Is it possible to manufacture munitions for the Invaders now?"

"That's okay, Team Korea."

"Okay, make ten groups of intruder slow-dropping bombs!" Han Feng ordered as he looked at the fighter planes.

Now I still have more than 100,000 gold coins in my "account", which is definitely enough to make some ammunition!

"Okay, Korean team, ten groups of intruder fighter planes' slow-drop bombs are being manufactured, please wait..."

After Luna finished speaking, Han Feng saw more than ten ground staff driving vehicles out of the warehouse in the Kongzhi headquarters building and heading towards the heavy factory.

Pulling a full load of bombs, the ground support vehicle returned to the air command center to load ammunition for the intruder fighter planes.

During this period, two pilots wearing blue air force uniforms walked out of the air command building and walked towards the intruder fighter jet.

"Report to the Korean team that the two aggressor fighter jets have been loaded with weapons."

"Let's take off." Han Feng nodded and said.

Before Luna responded, Han Feng remembered the voices of the two pilots in his mind.

"Report to the Korean team, Intruder fighter pilot No. 0001, requesting permission to fly!"

"Report to the Korean team, Intruder fighter pilot No. 0002, request

Clearance to fly!”

"Allow takeoff!" Han Feng ordered as he looked at the two fighter planes.

After receiving the order, the two pilots responded in unison: "Got it, Korean team!"

"Boom! Boom..."

Different from the last time they took off, this time, the two Intruder fighter jets took off in a normal "run-up" manner.

"Report to the Korean team! Please set the combat altitude, combat range, and attack target!"

A few seconds after takeoff, one of the pilots asked Han Feng in his mind.

"Free flight, target: zombie swarm. If there are too many people, blow them up for me!"

"Okay Team Korea, we understand."

"Whoosh! Howl..."

After responding to Han Feng, the two invader fighter jets soared up and shot straight into the distance!

Just tens of seconds later...the two Intruder fighter jets turned around and flew back, landing on the apron of the air command center.

These ten seconds included taking off, coming and going, aiming, bombing and landing...

Also...it's just over ten kilometers away. For a fighter jet, it doesn't even take the blink of an eye...

Turning his eyes, Han Feng looked at the sky above the corpses again...
To be continued...
