"Master, why are you so sad? 100,000 martial artists with internal qi have no chance of winning?" Li Yunfei asked as she looked at Hao Yun, who was frowning.

Now the entire Sky City is in a tense state, and even Li Yunfei, who has locked herself in the laboratory, knows that humanity is about to face a catastrophe.

"We're going to face a notorious race, and their finishing power is far above the earth. 100,000 warriors can only hold back the vanguard of the El, and if the El's large army arrives on Earth, the Earth will still not improve much, and the future of humanity will be worrying. Hao Yun sighed helplessly.

Hao Yun, who got historical records from Hao Ling'er, was not optimistic about this war. There was too little time left for him, and if the arrival time of the vanguard of the El could be extended to a year, Hao Yun was sure to pinch these grandsons to death. But four months is really not enough.

The El are a nomadic tribe with all the people in the army, and they are very similar to the historical Huns. It's just that the pastures they graze are vast starry skies.

Their source of income is the sale of slaves, and intelligent life slaves are very scarce in the starry sky, enough to cover the expenses of these fighting nations who are not engaged in production and are keen to fight.

Moreover, this kind of trade is a trickle, the population can multiply, and the El people can obtain a lot of profits in batches like cutting leeks after occupying a planet.

According to Hao Ling'er's statistics, there are 300 million people in the entire El clan, and the minimum combat power of these 300 million people is C-level, which means that the newborn child of the El is a C-level powerhouse.

Adult El people have B-level combat power, and elite El people can even defeat A-level powerhouses.

There are a total of 108 S-class powerhouses in the entire clan of the Els who crisscross the starry sky, and this data can crush the high-end combat power of the earth - there are no more than twenty S-level powerhouses on the earth!

In fact, according to the miracle of the earth, the probability of the birth of a strong person is not so low. However, when the earth's powerhouses reach the point where they can travel the universe physically, they will not squat in the middle of the earth.

According to Hao Ling'er, there are at least 70 strong people above the SS level in the history of the earth who have walked out of the earth, and these old monsters have a long lifespan, as long as they don't die and drill into the black hole, they are basically alive and well.

Three thousand years later, the strong man who sits in the Earth Human Federation-Changkong Dao Man is the strong man who walked out of the earth eight hundred years ago, that is, during the Great Song Dynasty!

In history, the catastrophe of the El people was not solved by modern earthlings, but the earth powerhouses who had gone out of the earth and traveled the starry sky found the same earth humans as themselves in the slave market, and then united many strong people whose ancestors were the earth to return to the earth and killed the El people before it was quelled.

At that time, except for the super life on the earth that survived and was hid in the shadows to fight guerrilla warfare with them like the third grandson of the El, the people of the entire planet were almost dead.

The only ones who have been rescued are the "plant powerhouses" who have been brainwashed and put in glass jars to act as breeding machines, and the babies with improved genes that have not yet been sold.

The brutality of the El people angered this group of strong people, led by the Sky Dao people, and after contacting many strong people, the earth powerhouses went deep into the starry sky and searched for the El people in the universe again.

It was a starry battle, and after half a year of inquiry, a pursuit team composed of 8 SSS-level powerhouses and 47 SS-level powerhouses finally found the El's lair on a colony star in the constellation of Centaur. Fifty-five powerhouses joined forces to carry the planet and threw it into the nearest star.

With these strong people blockading, all the warships of the Els are held back in the planet and cannot attack.

After this battle, except for the lucky ones who survived the sporadic travel, the entire civilization was completely wiped out in the brilliant fireworks of the stars.

The new civilization of the earth is faulty, and the new generation of earthlings has genes from the supernatural, so the chance of the birth of the strong is very high. After absorbing the technology left behind by the El, the new generation of new humans has firmly and forcefully embarked on a journey to conquer the starry sky.

However, Hao Yun doesn't want this kind of history to reappear, it is unrealistic to pin his hopes on the strong man in the starry sky, his parents and relatives are firmly rooted on the earth, and he will never allow anyone to destroy it!

"Isn't it true that only Gu Wu can compete with the Els? doesn't it mean that enchanted weapons can kill the Els?" asked Li Yunfei with wide eyes.

Hao Yun nodded: "But ordinary people holding enchanted weapons and attacking the Els is a death - this kind of hand-to-hand combat can only be done by martial artists." ”

"In other words, as long as ordinary people have the strength and speed of an ancient martial artist, they can also kill the Els with an enchanted weapon?" asked Li Yunfei's eyes sparkling.

Hao Yun touched his chin: "There's really nothing wrong with you saying that......

"Master, have you seen it?I think there is something that can meet the needs of the earth now, so that ordinary people can also have combat effectiveness!" Li Yunfei said with a small face.

Hao Yun's head jerked: "You mean... Mecha?"

"BINGO!" Li Yunfei stretched out her hands and drew a large circle, "If we develop a mecha that can be piloted by ordinary people, ordinary people can compete with the Els, there are millions of troops in Huaxia... There can be at least one million people who can go to war!" Li Yunfei continued: "Wouldn't our chances of winning be greater?"

Hao Yun's eyes lit up, and his mind immediately opened up: "What if we design an unmanned mecha? Let the mecha control it remotely, even if the El people break the mecha, it will only break a pile of scrap metal." ”

"I had an idea that we could develop a mech simulation game where the gamer's combat power was endless. Li Yunfei raised her small hand and said: "Our virtual reality system can allow many players to get started quickly, if the number of players is enough and the productivity can keep up, we can kill the Eles by piling up." ”

Productivity? With the backing of Hao Linger's underground factory, the most important thing for Hao Yun is productivity! As long as the raw materials are sufficient, the mecha can be mass-produced.

And there is a large metal ingot next to the earth, the moon, where the reserves of rare metals are even greater than those of the earth.

"You're awesome!" Hao Yun, who was opened up by Li Yunfei's new ideas, picked up the little girl and kissed her fiercely. With mechas, ordinary people will no longer be ordinary, who said that game otaku can't go into battle to kill enemies?

Li Yunfei returned to the research room to continue absorbing scientific and technological achievements, while Hao Yun went headlong into the underground factory.

"Isn't there a mecha technique, the best energy-producing kind!" Hao Yun asked urgently.

"Yes, yes, but at this stage, the earth simply can't get enough materials. Hao Linger spread her hands and said helplessly.

"So what?" Hao Yun asked with a depressed expression.

Hao Ling'er said: "So you can only exchange the data and production technology of each system of the mecha. These techniques are not valuable, but it will take your people to devise a mecha that fits the current situation on Earth. No way, the future mecha is not suitable for ordinary people, it is an exclusive product for high-end fighters!"

"Okay! Exchange technical data!" Hao Yun said eagerly.

"Although the mecha needs to be designed by you, the classic mode of internal control of the mecha has not been changed. The mecha has two control modes, one is a gimbal joystick and a virtual keyboard that is controlled by commands, and the other is directly controlled by the strong with mental power. There aren't many supernatural people on the planet right now, so the classic control mode of the gimbal joystick with the virtual keyboard is the most suitable... I can give you a set of mecha battle games for free, as long as you promote the virtual network, ordinary people can start to familiarize themselves with the operation of mecha from now on. ”

Hao Yun nodded, this is already the best situation, if only relying on the technology of the earth, the year of the monkey can develop a mecha that can be put into actual combat, with Hao Ling'er's technology, this process can be infinitely shortened!

As long as you have a mecha, there is hope for this battle!
