The system is one year ahead of schedule, but it’s not the end of the world yet!

When everyone in Mo City saw this, they immediately became confused. They did not expect that the aliens would react so quickly and fiercely.

"Attention everyone, activate the backup energy, activate the overload operation mode, activate all defense systems overload, and fight back with all your strength!" Akafiel picked up the transmitter on his body and immediately ordered loudly.

As his order was issued, various buildings and facilities in the silent city began to light up, and energy beams and light beams gathered from all directions to join the counterattack.

For a time, fierce battle fluctuations arose in the sky above the entire Silent City.

The alien spacecraft continuously fired energy beams and missiles, trying to destroy the defense facilities of Silk City. Silent City, on the other hand, relied on the city walls and various weapons in the city to fight back. With overload operation and the blessing of superpowers, the two sides were locked in a fierce tug-of-war.

However, the technological level of aliens is obviously much higher than that of Mocheng.

Their energy beams and missiles are not only powerful, but also extremely fast. They can often break through Mo City's defense at the moment when Mo City's defense is slightly neglected, and bombard the attack into Mo City, causing huge damage to Mo City's interior. of destruction.

"This is not the way to go. We must find a way to enter the spacecraft and face their fragile bodies in order to give full play to our advantages!" Du Renyuan said loudly.

"Fighting at close quarters? How can the deputy city master get up close? Fly up? What's the difference between that and dying?" someone retorted.

"No, we have a chance. Senior Gu Liu sent a message and Lin Xiaotian is back." Akafiel rolled his eyes and said immediately, "Mu Xiyue, can you continue to communicate with the alien just now through the spaceship? Ask him if he is willing to negotiate with us."

"It's impossible. They're already fighting. They definitely don't want to."

"I know, I'm just asking you to harass them to delay them for a while." Akafiel said with a smile.

Mu Xiyue nodded clearly and immediately tried to communicate spiritually with the alien. However, her attempt was ruthlessly rejected by the aliens.

"You despicable low-level creatures, are you worthy of negotiating with us? Wait until we destroy your strategic city, and then we will slowly settle accounts with you!" The alien's tone was full of arrogance and disdain.

Hearing the reply conveyed by Mu Xiyue, Akafiel's eyes suddenly turned cold. Although he had known for a long time that this battle would be inevitable once it started, it still made him uncomfortable to hear the alien's words.

"Everyone listen to the order and activate the final defense plan!" Akafiel ordered loudly.

As his order was issued, the buildings and facilities in Mo City began to undergo tremendous changes. The energy beams on the city wall became more dense and powerful, and at the same time, some high-rise buildings in the city began to deform and reorganize, revealing huge muzzles and energy transmitters.

These muzzles and energy launchers were left behind by Chen Mo before he left, in order to deal with this sudden crisis.

It has very serious side effects of use, because it will consume the energy of the planet. Fortunately, Chen Mo has built some equipment before that allows the planet to naturally absorb cosmic energy and convert it into planetary energy.

Occasionally using this ultimate defense method will not cause any damage to the planet's energy.

But once it is overused, it may take a long time to replenish it. This kind of defense launched by overdrafting the power of the planet is still very confusing.

Originally, even if Silent City was captured by the Survivor Alliance, they did not intend to use it easily. However, they never expected that they would come in handy at this time. As the ultimate defense system was activated and absorbed a large amount of planetary energy, it was seen that A series of extremely blazing energy beams violently blasted towards the alien spacecraft.

The aliens didn't seem to expect that Mocheng had such a trump card, and were caught off guard.

The spacecraft's protective shield, which had always been in invincible golden body mode, finally began to crack under the bombardment of this terrifying energy beam, and some of the equipment on the spacecraft also began to smoke.

"Damn it, how come these earthlings have such powerful weapons!?" the alien said in shock.

They found that they had underestimated the human technology of this planet. When they first arrived, they had actually tested and estimated the technological level of this planet.

Moreover, very contradictory estimation results were obtained. This planet has some very technological creations that transcend the times, but the overall technological level of the planet appears to be extremely low.

They only thought that there was some kind of information-sensing ability in the core of the demon source. They carried some technologies stolen from them and passed them on to the humans of this planet, and then developed some weird leaping technologies.

As a result, they never expected that the people on earth could actually launch a counterattack that was even more surprising to them.

The alien with a head like a round TV called Captain no longer dared to underestimate these earthlings, and immediately ordered the spacecraft to fight back with all its strength.

However, their counterattack did not have much effect. Mocheng's final defense plan was too powerful and complete, covering almost the entire city, making it impossible for them to find a breakthrough.

But they don't believe that the people on earth, who just showed that their technological level is obviously lower than their own, can really come up with any technological trump card that far exceeds their own.

If they had, they would have used it long ago, so they can easily come to the conclusion that the current offensive and defensive capabilities of the people on earth must not last long and are only temporary.

Just need to hold on for a while and it will be fine.

And the fact is indeed the case. An offensive and defensive war relying on the energy of the planet will definitely not be a long-term solution. If it continues, the alien spacecraft will not be smashed, but the earth will be blown up first.

Chen Mo did not leave behind such dangerous technology at the beginning. This defense system that relied on the power of the planet was just an application that Akafiel came up with by combining the defense system in Mo City and the "Endless Energy Tower" that Chen Mo had built before.

You only need to lead an energy output end to the Mocheng defense system and you can easily do it.

But there are two disadvantages to this.

In addition to the disadvantages mentioned above that it may overdraw the planet's energy, there is another disadvantage that it will definitely damage all the defense facilities in the silent city.

Once this absolutely overloaded energy is accepted and used for a long time, the entire defensive equipment in the silent city will definitely be unable to withstand the collapse before the earth's energy is exhausted.

Therefore, it is obviously unclear how long the current war situation can last.

Seeing that Mo City's defensive counterattack was effective, and some cracks appeared in the alien spaceships it fought, the superpowers in Mo City who were initially afraid of the alien civilization immediately saw hope, and excited smiles appeared on their faces. He started to launch his own supernatural attack and bombarded the alien spacecraft in the sky.
