"Is that you?"

Looking at North who came out of the one-man flying machine, Tongtian couldn't help frowning.

Back then, North used him as a guinea pig for research, and he didn't know about Qin Yan, but later he took the initiative to tell him, so North left in a hurry and never appeared again: In fact, for Qin Yan's death, both he and Wanyan felt guilty.

He thought that those people all had a grudge against him because of Qin Yan's death, and it was likely that they had found a place to live in seclusion without asking about the world.

"Isn't that weird?"

North, whose body was shrouded in a light film, said with a smile: "It's better to leave the first game to me." Your strength is indeed strong, but destroy that fortress...... The probability is very small, do you know what level that fortress is? Its spatial shield is simply not something you can break. ”

"You're alone?" The sky was shocked.

"That's right."

North once again showed a great sense of superiority, and he held his head high and his face was full of pride: "What? Old man, are you underestimating me? ”

"How do you know there's something going on?" Tongtian still thinks it's a little weird.

"The technology I have mastered is not much worse than that of the demons."

"What do you mean?"

"30 years is enough for me to do many, many things."

North, who was still full of pride, pointed to the starry sky and said, "You have always been just moving in a small area outside the defense line. A little farther away, I have already installed a large number of monitoring instruments, and all the changes here cannot escape my surveillance. ”

Without waiting for Tongtian to speak, North pressed a few times on the instrument on his wrist, and then a large battleship flew from the void at more than a hundred times the speed of sound.

So, something happened that stunned Tongtian.

It was a huge ship with a length of several kilometers, more than a circle larger than the largest warship of the Demon Clan that he had seen before.

That's right!

This is exactly more than 10,000 years ago, the mothership of the demon fleet during the first war of gods and demons, which was destroyed and buried under the moon.

Many years later, Qin Yan turned North from an awakened electronic life into a real human, and North used the technology he mastered to rebuild this super mothership - even the current demons have built countless warships in the past many years, but they are only manufactured with the help of production lines, and those people have not mastered the technology to make motherships, so even those demons can't build warships of this level.

Immediately after the mothership, warships of different classes, large and small, followed in an overwhelming manner, with more than 2,000 of them.

This is no longer the case.

The demon side is already preparing to attack on a large scale, and the combat power of the human side is obviously insufficient, so there is no need to hide the so-called scientific and technological power.

Seeing the fleet in front of him, everyone from Tongtian to Tongtian was stunned, and Tongtian took a long time before he shouted: "These ...... Did you make it all up? ”

"Time is too short and resources are limited, so ......"

North reversed the arrogance just now, and his expression became solemn: "The other party has been consuming in the war over the years, but what it has produced will definitely exceed what it consumes. In 10,000 years, the number of warships they have must far exceed the warships I have built. Frontal conflict is obviously impractical, so we have to think of a better way...... As for the fortress of the demons, it is not a big problem. ”

"How do you conquer the Demon Fortress?" Tongtian asked.

"It's simple."

He pressed a few more times on the instrument on his wrist, and the mothership opened a portal, and a large group of people walked out of it.

Compared with the more than 100,000 people convened by Tongtian, these people are indeed a lot less, but in fact there are not many, there are nearly 10,000 people.

Among the several people at the head, Tongtian saw familiar faces.

Yun Jin......

Lou Yuqing......

Cangyue ......

Qiao Yunjiao......

Ou Tianqi ......

These are the people who left from this line of defense under the leadership of Lou Yuqing back then, but today they not only came back, but also brought more people.

There are the original team of the Purple Light Holy Order, the people that Qin Yan brought from the various families of the Immortal Martial Realm, the children of Cloud City, and the people brought over from the earth.

Among them, the second time Qin Yan returned to the earth, there were thousands of people who brought him over.

Today, all of these people are here.

"You ...... Let's go. ”

Tongtian frowned, but finally shook his head: "North, use your technology to get them out of a safe place, this war is not for them to participate in." I have already said back then that I will not let you sacrifice again, this is my promise, and it is also what I owe to Qin Yan. ”

"Master, do you think they are too weak to play a role in the war?" Yun Jin broke through the idea of the sky.

"Yes." Tongtian does not deny it, which is also one of the reasons.

"It is Qin Yan's dream to exterminate the demon clan, we just want to fulfill his dream, and at the same time avenge him, whether the predecessors allow it or not cannot change our decision."

The phoenix took a long breath and said, "What's more, we are no longer cannon fodder!" ”

Call!

More than 10,000 people released the Talisman True Gang at the same time, and at the same time, a large number of distorted ripples appeared in the void - this is a symbol of the power of space.

Tongtian was dumbfounded on the spot.

How could it be......

Although it is said that even if there is no Divine Blood Pool, as long as it is a martial artist from the earth and a descendant of the ancestors of the Source Star, he can break through the barrier of the Heavenly Martial Triple Heaven through cultivation. However, the difficulty of cultivation was beyond imagination, it had only been 30 years, how could they have improved so amazingly?

Among the more than 10,000 people, there were more than 300 Tianwu Quadruple Heaven masters, and some of them had reached the middle and late stages of the Tianwu Quadruple Heaven!

Fantastic!

This kind of terrifying increase in speed, even Qin Yan may not be able to achieve it, right?

Yes.

This is what they have achieved in the past 30 years, with the help of high-tech combat equipment and the effect of memory replanting, in countless battles of life and death, they have obtained incredible gains.

"They ......" Tongtian pointed to Cangyue, Qiao Yunjiao and the others in surprise.

If you want to say that Phoenix, Lou Yuqing, Pojun and others can break through, it can be said, but Cangyue They are all natives of the God Domain.

"It took me 17 years to finally find the crux of the problem."

North smiled and said proudly: "Finding problems and solving problems is the attitude that a scientist should have, so they also have the same potential as human beings on the earth, and have the opportunity to ascend to a higher realm...... Of course, you don't understand the details - take out the things that deal with the demon fortress! ”

Moments later, dozens of people came out carrying a box of space large enough to hold a football field.

North only has a sixth-level civilization derived from the Alpha Star, and the space technology is relatively limited, and the palm-sized space box only has a space of 100 meters in length, width and height, and the only way to expand the space capacity is to increase the size of the space box itself.

What is in such a large space box?

"Let's go! Everybody get out of the way! North snorted with arrogance.

Hula!

Everyone retreated into the distance, and North withdrew the ships he controlled far away, and repeatedly kept the others farther away.

In the end, when he remotely activated the space box through the instrument on his wrist, Tongtian's legs were weak and almost didn't fall, and his eyes were about to pop out.

What is this?

Fortress!

A steel fortress on a scale comparable to the Demon Fortress, with a diameter of more than 2,000 kilometers and countless cannon barrels!

For the demons, the steel fortress that has existed for 10,000 years is undoubtedly their strongest weapon, because only on such a large fortress can the most lethal weapon be installed. However, this kind of fortress is useless in high-tech warfare, and can only be used in the war with the humans of Earth.

Why?

It's very simple, because with the scientific and technological power of Alpha Star, they can only build a four-star warship, if the battleship is too large, although their technology can push it, its flexibility and speed will be greatly reduced, and it will become a useless live target in interstellar warfare.

Without high technology on this side of the earth, this huge fortress will become the most terrifying war machine, and it is also the biggest killer weapon of the demons.

But!

What if there were such war bastions on the human side?

"There will be no one in my fortress, there is only one purpose, to die with the other party's fortress."

North shrugged his shoulders and said, "As long as the other party's fortress is destroyed, their plan to win the war at the minimum cost will be frustrated, but ......"

He didn't continue, but Tongtian knew very well what he meant: the war fortress is not the only weapon of the demons, after the fortress is destroyed, their massive warships will pour out, and there will be an extremely tragic war, and no one dares to guarantee the outcome.

"Let's get started!"

Tongtian nodded, although he still had no bottom in his heart at this moment, the arrival of North and the others undoubtedly brought him the greatest help.

With two hours to go, a decisive battle will be played out in the starry sky and the final countdown to the war will begin.

As expected!

The demon fortress did not go all the way, but stopped at a distance of about fifty thousand kilometers from the defense line.

This distance exceeded the attack range of the Tenmu Sixfold Celestial Warrior, but for a high-tech weapon, it was within the attack range. In particular, the planetary-class railgun installed on the fortress is lethal enough to extend to more than 200,000 kilometers, and even if it is separated by 50,000 kilometers, the lethality can still reach three to four percent.

The fortress suspended in the void suddenly opened three huge portals, and a super giant cannon barrel with a diameter of thirty meters stretched out, and then a red flame of light condensed on the muzzle.

This is the most powerful planetary-class railgun!

This time is the final decisive battle, and the other side even uses the war fortress, in the face of this kind of super firepower killing weapon, of course, Tongtian will not be stupid enough to mobilize men and horses into the defense line to confront head-on as before, which is equivalent to sending food to the other side - this war requires sufficient strength, and it also requires a certain amount of resourcefulness.

Rumble......

Three completely illuminated tens of thousands of kilometers, the thick and incomparable crimson beam flew out of the demon fortress and went straight to the formation defense line at the speed of light.
