"How?" Seeing that Tony Stark was a little dumbfounded, Su Fei rolled his eyes and said with a sigh.

"The universe is so big, ten years is really not enough, Tony."

"Come less." Tony Stark smiled coldly, "I don't believe that in Asgard, you didn't do anything good, and when it's really dangerous, you will definitely be able to contact Heimdall." ”

"Thor has boasted about the power of the Rainbow Bridge in front of us."

"You actually saw through it." Su Fei put away his bitter face, and immediately said with a serious face, "Then let's talk about a deal." ”

"That's what you're waiting for." The corners of Tony Stark's mouth curled, and he handed over a glass of champagne and said, "Let's talk in another place, Dr. Banner, are you coming?" ”

"No, I'm not interested in your deals."

in the living room.

"The technology tree of the alien civilization, especially the space technology and energy technology, if it can't be 200 years higher than my current technology, then give it to you or Thor, that kind of god-like technology."

"You mean rune technology like Asgard." Su Fei's eyes were suspicious, and he looked at Tony Stark, who seemed to be talking casually, seriously, and said.

"It seems that you haven't been fighting Asgard's technology for a day or two...... But Tony, why don't you just talk to Thor? ”

"Is it useful, he promised to say again, this is the power of the gods, and it should not be controlled by mortals...... I don't want to be ridiculed by him, whatever, my terms, to trade or not to trade. ”

"No problem, but before I leave Earth, I need 2 more of these energy cubes."

"I don't have so many materials in my hands, and the elements that make this kind of energy are controlled by the major countries in the world, but if it's a little smaller than this, I can make a few pieces."

"That's a little smaller." Su Fei thought about it and agreed to this request, after all, the transaction between the two was still a conversation between friends, not that kind of cold business.

"Deal."

After a while, Bruce Banner watched the two men come in with a happy face, and immediately quipped, "I thought you would talk for an hour." ”

"Friends, that takes so long." Tony Stark said, then looked at Su Fei, "Come on, let's see how you're going to take this big guy away." ”

"Let's talk about it first, don't be surprised." Su Fei stepped forward and reminded.

"I'm just waiting to see the show."

"Okay." Seeing the two of them shrug their shoulders, Su Fei went straight to the energy cube and put his hand on it.

Shout!

The next moment, the two of them saw the energy cube the size of the basin suddenly disappear into the air.

Shout!

In an instant, the energy cube appeared intact in its original position, but in a moment, it disappeared into Su Fei's hands.

"Space technology?" Bruce Banner, dumbfounded.

Tony Stark also patted his forehead with a look of amazement, "This is stable space technology, right, you have already mastered it, I should have guessed, your magical transformation, right?" ”

"Oh shet...... Su Fei, you actually lied to me again. ”

"Come less, you should have guessed it a long time ago, otherwise when you traded just now, how could you be so happy and leave." Su Fei smiled, turned around and waved his hand.

"Don't forget, you promised me the cube of energy."

Leaving Tony Stark's laboratory, Su Fei returned to the plane, looked at Zhao Fei'er and Erin who were waiting here, and directly said go home, and after telling them not to enter their room, he closed the door directly.

"Enter the base of the canyon." The moment he was lying on the bed, Su Fei said silently.

In an instant, Su Fei's body twisted, and when he opened his eyes again, he was already in the canyon square.

Call......

A gust of wind struck, and the elf fairy flew out of the crystal and landed in front of him, saying with a longing face.

"Rune's Child, it's been a month, have you found the energy cube?"

"You don't think that's going to work." Su Fei stretched out his hand, and suddenly the energy cube of the Ark Reactor appeared in his hand.

"It's huge." The elf fairy's eyes lit up, and he hurriedly stepped forward and touched it, urging with a happy face, "Come with me, hurry up." ”

The two of them immediately walked in front of the crystal base.

"Put your hand on it, and the little crystal will feel it." Elf fairy couldn't wait to remind.

"Little Crystal?" Su Fei looked up at the behemoth in front of him, and then looked at the elf that was no more than the size of a palm, and wanted to complain, but he was still obedient and pressed his palm on the surface of the crystal base.

"Do you want to activate the Crystal Base?" A cold mechanical voice suddenly appeared in his mind.

"Yes."

"For initial activation, it costs 500 gold."

“.......”

"Crystal base activation, current level 1, energy storage 500/3000, can maintain normal operation, unable to establish an effective base ......"

"Whether it is charged or not, the energy reaches 3000, the crystal base will upgrade itself, and after the upgrade is successful, you can build a building below level 2 and restore energy by yourself."

"Yes." Su Fei nodded.

"Detects available energy and starts charging."

Airplanes......

Su Fei felt the palm of his hand dragging the energy cube lightly, and saw that the gray surface of the crystal base suddenly bloomed with a bright light, and an energy ray shot out from within it, shining on the energy cube.

Flutter .....

The energy cube floated up, and was pulled closer to the crystal base by the light, passing through the gray-white surface, and directly submerged into the crystal base.

After a while, Su Fei saw that on the huge volume of the crystal base, the gray-white surface crystallized, like rippling water, constantly emerging, like a recovering light, and exuding a thick vitality.

"Wow, so full, so comfortable!" At this time, a lazy and happy moan came from the elf fairy on the side, and his whole person seemed to become more energetic, and there was a light embellishment around his body, and the whole body turned into a ray of light, and also entered the crystal base.

Airplanes......

"The energy is sufficient, and the upgrade is successful."

In a short period of time, Su Fei saw that the crystal base, which was originally as gray as garbage, became dazzling, and its level not only went from the previous level 1 to level 4, but its energy also spread to the entire square.

The first thing to change was the crystal base itself, which floated directly from the ground of the square, and within the original crystal base, there was an energy shield to completely protect it.

Then, in the four right-angled directions of the square, there are two crystal battle towers to defend it.

At the top of the tower, there is a terrifying gathering of energy, as if if if an enemy will attack it, it will unleash a devastating attack.

It is worth mentioning that the area of the square has also expanded from the previous kilometer radius to a 5,000-meter radius.

And that's not all.

Because on top of this canyon square, there are new buildings, and they rise automatically.

An altar with a radius of ten meters appeared 50 meters away from the southwest of the crystal base, and there was a warm ball of light above the altar, and the energy emitted from it made Su Fei feel full of vitality.

"Level 1 Altar of Resurrection." At the moment when the altar was completed, a line of words suddenly appeared in the bottom of Su Fei's heart, and at the same time, the changes in the entire canyon base came to an abrupt halt.

A seven-colored light, when Su Fei was still a little stunned, suddenly shone on his body from the inside of the crystal base, enveloping him firmly.
