Since three months ago, the human race has risen rapidly with lightning speed, and in the blink of an eye, it has destroyed three giant cities of the Protoss and severely damaged the powerful East China Sea Shark Race.

The hundred races paid attention to the human race again, and the human race, which seemed to them to be no threat, suddenly broke out with such a big noise, which made them not react for a while, so that the human race had a period of stable development.

However, for the past three months, many alien races have also been peeking into human cities, probing the reality of human beings.

Maybe it was Liu Xingchen who cleaned up the aliens too thoroughly on the day of the sacrifice, dozens of kings and tens of thousands of elites of various races died lifelessly, and no aliens knew what happened that day, which made the hundred races suspicious, and even guessed that there was an existence beyond the king in the human race, otherwise why so many kings didn't run away, so they didn't dare to act rashly in a short time.

The aliens who were in charge of spying on the human race, seeing the humans tear down the huge cities they lived in and turn them into seemingly defenseless dwellings, marveled at the speed with which they had built them, and at the same time laughed at the stupidity of the human beings: they had torn down the tall walls and what they could do to resist their attacks.

Then, they see that the humans spend most of their time in their homes, doing nothing (in fact, they are all in a virtual classroom). However, within a few days, all the human beings suddenly became stronger, and everyone had at least the strength of the god of war, which made the hundred tribes feel frightened, what if they all became kings in a few days.

In fact, this is the completion of the completion plan of all human beings, and it is impossible to go any further, in a short period of time, but the hundred races don't know ah, they are afraid of the growth rate shown by human beings.

Under the fear of humans, the hundred races united again, they decided not to wait any longer, and prepared to launch a wave of beast tides to test the reality of human beings, and then just like they did against the human base, they used a steady stream of attacks to slowly consume the power of human beings, anyway, their low-level units were originally used to consume.

The hundred clans thought that under the attack of the endless beast tide, even if these humans were all god-level powerhouses, they would never be spared, not to mention that these humans also foolishly demolished the city wall.

Soon the Hundred Tribes began to launch a beast tide, this time they were acting together, no longer fighting each other, and the unified goal was to attack the human city.

In the plan of the hundred races, the feather clan will attack from the sky, and at the same time be responsible for destroying those human aircraft, the sea clan will land from the East China Sea to merge the beast clan and the zerg to attack from the land, most of the spirit clan is difficult to move, and will be responsible for turning the human city into a dangerous jungle with the cooperation of all races, and the god clan is also involved, they want to rely on the same appearance as humans, blend into the human race and wait for an opportunity to cause turmoil.

Without the harsh natural environment of Antarctica as a barrier, the races will attack humanity from all directions, including the sky and even the underground, believing that even if humanity is mysterious and powerful, it will not escape the fate of destruction.

As soon as the Hundred Races made a move, humans discovered their movements, which originated from the multiple satellites in orbit above the Earth, and humans brought the entire Earth under surveillance.

Some of these satellites were launched during the era of human bases, and now they are being reconnected and controlled by human beings, and some of them have been launched recently, especially the satellites that have been launched recently, with a higher level of science and technology, and also carry very powerful space-based weapons.

For human satellites, these alien races have no way, because they can't go up, even the king of the feather clan is only a mortal-level creature, and they can't survive in space at all, in fact, they can fly to the top of the stratosphere of the atmosphere is the limit, and the satellite is at least a few hundred kilometers higher than this.

In the conference room of the Supreme Staff Headquarters of the Human Civilization and Operations Department on Earth, the new generals were discussing tactical deployment fiercely while looking at the real-time movement map of the alien race sent by the satellite.

Liu Xingchen is not ready to participate directly in this war between human civilization and alien races, he hopes that these people can grow up in the war, and in the future, human civilization will go to the interstellar, and dealing with other civilizations is indispensable for war, so if human civilization wants to develop, it must rely on all human beings, not himself.

Some of the people in the War Department advocated that they should take the initiative and use the information superiority to annihilate the aliens before they could converge.

Some advocate defending in other directions, and then concentrating superior firepower to clear one of the sides first.

Some also advocate using strong force projection capabilities to attack the large rear of the various tribes, forcing their alliances to dissolve and attack them in a divided manner.

In short, each combat plan has its own advantages and disadvantages, Liu Xingchen did not give an evaluation, let them make their own choice, and finally everyone took into account the limited manpower, chose a more conservative defensive and offensive strategy, prepared to fight to nourish the war, constantly expand their strength in the battle, and finally counterattack, and then they continued to formulate a detailed battle plan.

The reason why they are so confident is that the technology provided by Liu Xingchen is too rebellious, in the war, human beings don't need to go to the battlefield in person, and it is the same infinite mechanical army that fights against the infinite beast tide.

These combat robots are simple, inexpensive and lethal, and the production department can produce millions of units per minute at full power, and will continue to expand production capacity in the future as the number of underground mining vehicles increases.

The human soldiers use their consciousness to synchronize the powerful biochemical armor, invincible on the battlefield, even if they are damaged, they can immediately change into new armor, and continue to go to the battlefield, the strong will of the evolutionary can also ensure that they continue to fight for a long time.

In addition, there are also biochemical war beasts transformed from alien corpses, and the utilization rate of alien corpses by both humans and gods was too low before, which was nothing more than eating their flesh and using their hard carapaces and minions to make weapons.

As the war progresses, the strength of human beings is increasing, and there is also the existence of black technology such as material converters, so that human beings have no worries about material and energy shortages on the earth, so the final victory must belong to human beings!

Seeing that the many generals of the General Staff Department had determined the final operational deployment, Liu Xingchen appeared in the conference room, and everyone in the audience stood up with a bang, and saluted him neatly:

"Sir!"

Liu Xingchen returned a salute:

"Don't be so restrained, sit down, I heard your discussion and combat deployment just now, it's very good, I will watch your battle, do you have the confidence to win?"

Everyone replied in unison, Liu Xingchen was very satisfied with their momentum, and then said:

"Faith is good, but you should not take it lightly......"

After Liu Xingchen encouraged everyone in the war department, he left.

After leaving the War Department, Liu Xingchen went to the Production Department, the Academy of Sciences and other departments to do pre-war inspections.

Liu Xingchen has a title in each department, such as chief, dean, mentor, boss, and even head of state.

This is also the beginning of human civilization, many things need Liu Xingchen to take the lead, in fact, Liu Xingchen does not have much desire for power, it is really tiring to take care of everything, how can there be time to pursue a higher level of life.

When the new generation grows up, Liu Xingchen will gradually resign from these positions and only be a guide of human civilization, walking with the civilization of the earth
