"What?" Seeing Tony Stark was a little dumbfounded, Su Fei turned his eyes and sighed.

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

"Stop coming." Tony Stark smiled coldly, "I don't believe that in Asgard, you won't do anything good. When it's really dangerous, you will definitely be able to contact Heimdal."

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

"You actually saw through it." Su Fei put away his bitterness and said seriously, "Then let's talk about a deal."

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

"No, I have no interest in your deal."

In the living room.

"If the technology tree of alien civilizations, especially space technology and energy technology, cannot be higher than the 200 years of my current technology, then I will give you or Thor, a kind of magical technology."

"You mean rune technology like Asgard." Su Fei looked suspicious and looked at Tony Stark who seemed to be talking casually.

"It seems that you have been fighting Asgard's technology for a day or two... But Tony, why don't you tell Thor directly?"

"Is it useful to say that? He promised to say another sentence, this is the power of God and should not be controlled by mortals... I don't want to be ridiculed by him. How about it, my conditions, trading or not trading."

"No problem, but before leaving the earth, I will need 2 more energy blocks like this."

"I don't have so many materials in my hand. The elements that make this energy are controlled by major countries in the world. However, I can make a few smaller pieces of them."

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

"make a deal."

After a while, Bruce Banner watched the two of them come in with a happy look on their faces and quipped, "I thought you would talk for an hour."

"That will take so long between friends." Tony Stark said, then looked at Su Fei, "Come on, let's see how you are going to take this guy away."

"Don't be surprised first." Su Fei walked forward and reminded.

"Just wait to see the show."

"Okay." Seeing the two of them shrugging, Su Fei went straight to the energy block and put his hand on.

call out!

The next moment, the two saw the energy blocks as big as basin suddenly disappear into the air.

call out!

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

"Space Technology?" Bruce Banner said silently.

Tony Stark also patted his forehead with amazement, "Is this stable space technology right? You have mastered it a long time ago. I should have guessed that your magical transformation is the same, right?"

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

"Stop coming, you probably guessed it long ago, otherwise it would have been so happy when the transaction was just now, and I left." Su Fei smiled and turned around and waved.

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

After leaving Tony Stark's laboratory, Su Fei returned to the plane. Looking at Zhao Feier and Erin who were waiting here, he said directly to go home and told them not to enter their room, and then closed the door directly.

"Enter the canyon base." Su Fei murmured as he lay on the bed.

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

call......

A breeze hit, and the elf fairy flew out of the crystal and landed in front of him, saying with a longing look on his face.

"Son of Rune, it's been a month since you found the energy block?"

"Do you think this is OK?" Su Fei stretched out his hand, and the energy block of the ark reactor version appeared in his hand.

"So big." The elf fairy's eyes lit up. After quickly approaching and touching her, she urged with joy and joy, "Come with me quickly."

The two of them immediately walked to the crystal base.

"Put your hand up and the little crystal will sense it." The elf fairy couldn't wait to remind him.

"Little Crystal?" Su Fei raised his head and looked at the huge creature in front of him. He couldn't see the elf as big as a palm. He wanted to complain, but he was still obedient and pressed his palm on the surface of the crystal base.

"Do you activate the crystal base?" A cold mechanical voice suddenly appeared in his mind.

"yes."

"For the first activation, 500 gold coins are required."

“……”

"Crystal base is activated, current level 1, energy storage is 500/3000, can maintain normal operation, and it is impossible to establish an effective base..."

"Whether the energy is charged, the energy reaches 3,000, and the crystal base will be upgraded by itself. After the upgrade is successful, a building below level 2 can be built, and energy can be restored by itself."

"Yes." Su Fei nodded.

"Available energy is detected and charging begins."

Buzz...

Su Fei felt a lighter in his palm dragging the energy block, and saw a brilliant light suddenly blooming on the gray surface of the crystal base, and an energy light inside it shot out, illuminating the energy block.

Puchi...

The energy block floated up, pulled closer to the crystal base by light, passed through the grayish-white surface, and directly penetrated into the crystal base.

After a moment, Su Fei saw the gray-white surface crystals on the huge volume of the crystal base, like rippling water waves, constantly emerging, like a revived light, and exuding a strong vitality.

"Wow, so full, so comfortable!" At this time, a lazy and pleasant moan came from the elf fairy beside her, and her whole person seemed to have become more energetic. There was light around her body, and her whole body turned into a ray of light and entered the crystal base.

Buzz...

“Energy is sufficient, upgrade is successful.”

In a short time, Su Fei saw that the crystal base, which was originally as gray as garbage, became dazzling. Not only did its level directly reach level 4 from the previous level 1, but its energy actually spread to the entire square.

The first thing to change is the crystal base itself, which floats directly from the ground of the square. There is an energy shield inside the original crystal base, which completely protects it.

Then, in the four right angle directions of the square, there are two crystal battle towers for guarding each.

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

It is worth mentioning that the range of the square has also expanded from the previous radius of 1,000 meters to 5,000 meters.

And this is not over yet.

Because there are new buildings on this canyon square that rise automatically.

An altar with a radius of ten meters appeared 50 meters southwest of the crystal base. There was a warm ball of light above the altar. The energy emitted from it made Su Fei feel vigorous.

"Level 1 Resurrection Altar." At the moment the altar was completed, a line of words suddenly appeared in Su Fei's heart. At the same time, the entire canyon base changed abruptly.
Chapter completed!
