"You're done!"

Nie Bing suddenly smiled at the battle song, and with a big hand grasping the void, a void hammer appeared in his hand.

Suddenly, the clear sky around him was turbulent, and the Hammer of Void was shining with bright stars. An invisible force field locked on gravity and acted on War Song's body, causing his face to change drastically.

"Vientiane Blacksmith! You opened the second door? ”

War Song's pupils shrank, and his body flickered, and he had to avoid the Hammer of Void.

But under the action of Nie Bing's gravity field, his body was like falling into a quagmire, and he instinctively raised his hand to gather star power and punched out. But under the shadow of the huge Hammer of Void, like Tarzan pressing on the top, his fist seemed to attack the iron.

Bang vein textures lit up on the body, the power counterattacked the heart, and the war song didn't even let out a howl, and fell headlong.

Nie Bing's feet moved, and he copied the war song, and a vitality was injected into the war song's body, and the war song woke up slowly.

"Ahem, Xiao Nie, you finally succeeded."

War Song's eyes returned to peace, but his life passed as quickly as a funnel.

"Warsong-sama!"

Horton and the others all gathered around at this moment.

"Hehehe, I can finally be free. Thank you, thank you, Xiao Nie. ”

War Song smiled kindly at everyone: "I shouldn't have appeared in this era in the first place, because of my thoughts, I brought so much pain to the earth. But now it's all over. ”

Zhan Ge turned his head to look at Nie Bing, and suddenly his face flushed, "Xiao Nie, promise me one thing." ”

"Warsong-sama, you say."

Nie Bing held back tears.

"Xiao Nie, the earth is now uninhabitable for human beings, and the space city will also collapse due to the weakening of the earth's gravity, you have to transfer humans to Mars in the shortest possible time, where I have been there before, leaving something behind. I want to use your means to make humanity survive there in peace. ”

"Warsong-sama, don't worry. I'll do it. ”

Nie Bing nodded heavily.

"Okay, then I'll be relieved."

Zhan Ge reached out and wanted to pat Nie Bing on the shoulder to show encouragement, but when his hand was halfway up, it slipped weakly. The battle song passed away with a smile.

"Warsong-sama!"

Everyone wept. The first hero of the earth passed away like this.

Nie Bing used Xingchen Iron to create the remains of the coffin into a funeral battle song, and released obituaries around the world to mourn the world heroes.

……

Three days later.

Nie Bing asked his younger brother and Wang Lei and others to stay in the Space City to assist Dongfang Qiming and others in arranging human immigration to Mars.

And he has to go to Mars alone to open a shipping route.

Nowadays, the earth's environment is harsh, the ecology has been out of control, and human beings still have three months of living space at most.

And the fastest warship on Earth takes a month to travel to and from Mars, counting the population and the number of warships, if you want to emigrate all of them, it will take at least a year or more. But then it was too late.

At present, only Nie Bing has found a way to build a space bridge between Earth and Mars, so that people can quickly transfer in large quantities.

Outside the spaceport, a small one-man spaceship made of star iron is being filled with the final supplies.

Nie Bing stood in the hall and watched the many teams seeing them off, hugging and saying goodbye to everyone one by one.

"Brother, be careful all the way. Ah Meng will take care of himself, you don't have to worry about me. ”

Nie Meng's eyes were a little moist, and he hugged his brother hard.

"Nie Bing, come back early, don't let my mother and them worry about you."

Wang Lei also came over to hug Nie Bing.

"Brother Nie Bing......"

Zhao Yunduo looked at Nie Bing, biting her lips lightly, with tears in her eyes, she threw herself into Nie Bing's arms, reluctant to give up.

"Alright, let's all go back. I'll be back to pick you up soon. ”

Nie Bing gently helped Zhao Yunduo up, then waved goodbye to everyone, and resolutely stepped onto the spaceship.

Now that the earth is still in dire straits, he doesn't have time to grow up here, because if he delays for a second, countless lives may be lost.

The ship activated, and a ray of light disappeared from view.

"Teacher Dongfang, how long do you think it will take for Xiaobing to build the space bridge this time?"

Horton stood beside Dongfang Qiming in a regular manner, looked at the direction of Nie Bing's departure and asked.

"I don't know."

Dongfang Qiming shook his head, "Although the Earth is not far from Mars, it is not so easy to build a space bridge between the two planets. After all, flying is only a jump into the dark universe, and the space is stable.

And erecting a space bridge requires operation in an unstable universe; Meteorites, meteor showers, nebula storms, gravitational magnetic fields, and space distortions collapse, and if any one of them goes wrong, the space bridge will collapse. If people are lost in space, they may not be able to come out for centuries. ”

When Dongfang Qiming said this, he couldn't help but think of the prison-like days in the Golden Palace of the Secret Realm, and his heart palpitated.

Horton didn't ask again, after all, he couldn't help except find a way to help people on this side of the earth. For Nie Bing, he could only wait.

Look at the crowd of people who saw them off behind, most of them were representatives of various regions, and they all pinned their hopes on Nie Bing.

With a three-month countdown, if Nie Bing can't come back, they will have to pick out some of their relatives and stay on Earth forever. It would be a heart-rending parting. No one wants to see that moment.

So they hoped that Nie Bing would come back soon.

In the vast starry sky, a point of light travels quickly.

Nie Bing set the spaceship to autopilot, and he entered the cosmic gear.

Although it is not the first time for him to build a space bridge between planets, he has no clue about how to control time.

Fortunately, behind the second gate was a huge study, and he was sure that there must be useful technology inside.

Looking up at the huge bookshelf, Nie Bing browsed the labels on the shelves, and stopped when he walked under the bookshelf with the space technology label written on it.

Reaching out and injecting the power of all things into the bookshelf, a cloud of light and shadow lit up, and the books on the bookshelf showed a brief introduction to the contents.

"Space Bridge Architecture! This is it. ”

Nie Bing took down the book covered with blue stars from the third row and opened it to read.

There are many space bridge architecture technologies introduced in the book, but some of them are not yet controllable with his current strength and are directly ignored. There are also some technologies such as spatial positioning and spatial defense, which are not of much use to him now.

After rummaging through dozens of techniques in a row, he didn't find a suitable one.

I wanted to change my thinking, but suddenly my fingers moved, and the page turned to the end, and a line of labels attracted him.

Space bridge folding technology can fold different dimensions between the universe in a single point for series.

"This is it!"

Nie Bing was overjoyed, folding and connecting in series, this is like the compression method of an accordion, which can greatly shorten the distance through space by folding and compressing the long distance into a tight one.

Nie Bing took the book and hurriedly read it carefully.

This space bridge folding technique is not just as simple as shortening the distance, if used correctly, it can even be transformed into combat skills or defensive skills.

It is conceivable that if you quickly build a spatial folding defense system when you are attacked by a strong person, then the opponent's attack is likely to shuttle into the space, and in the next blink of an eye, it will appear from behind and attack yourself.
