Spoilers for all the worlds

He said to himself in his heart, "I really hope that I can control all the power of Dingding... not the power of the current level. But a power that is stronger and purer, able to crush the alien colonization, and let the gentle man from back then Teacher Songyang comes back and has the power to protect everything."

"So, please." After Sakata Gintoki finished praying, he calmed down his mood, concentrated all his evil power on his palm, and threw it towards the random star.

He no longer looked at the random star, leaving everything to fate, and at the same time, he also strengthened his previous thoughts in his heart.

Sakata Gintoki kept reminding himself in his heart that if the random star gave him weak strength, he would not be able to recover from the fall.

If you really can't rely on external forces, you should practice harder. Use your own hands to achieve your ideals.

With a crisp buzzing sound, a brilliant brilliance merged into Sakata Gintoki's body.

After sorting out the information that emerged out of thin air in his brain, Sakata Gintoki's expression changed, and there was a hint of astonishment in his pupils.

After a brief silence, Tony Stark broke the silence and asked with interest, "What power did you gain?"

Sakata Gintoki was silent for a long time, and then he spoke softly, "What I obtained is a special item called the Any Door."

"This arbitrary door carries the star map of the solar system. In other words, theoretically, I think it can go to any corner of the earth, or even to any place in the solar system... If you are not afraid of death, you can even go to the sun. .”

"Of course, the Any Gate can actually go outside the solar system... But the Any Gate does not carry maps or star maps outside the solar system... So, I have no way to leave the solar system."

Sakata Gintoki's mood was very complicated. He obtained this item, and it was naturally worth a lot of money. But the help to him was not as great as expected...

"Is it involving space?" Tony Stark looked serious. A strange portal that could break the constraints of space and travel to any corner of the solar system, or even outside the solar system... This reminded him of the space gem.

After Bruce Wayne considered it for a moment, he suddenly said, "You just said... that thing is a pure technological creation, right?"

"...Indeed." Sakata Gintoki looked at Bruce Wayne with some confusion, not understanding what he meant.

"In other words, that thing can be analyzed by us. Can we even study the technology contained in that portal?" Bruce Wayne's eyes lit up, and he stared at Sakata Gintoki seriously.

Tony Stark's body was also shaken. Yes, there are fundamental differences between technological creations and non-replicable items such as space gems.

And if this kind of portal that can travel through the solar system at will is manufactured on a large scale, it will be easy for human civilization to upgrade to cosmic civilization.

"In other words, Iron Man and Batman...are you two very interested in the portal in my hand?" Sakata Gintoki expelled the messy thoughts in his mind and looked at the two hesitantly.

"Yes!" Bruce Wayne nodded calmly. He thought for a while and said, "Let's make a deal. Lend me the Any Door and Tony Stark for research. As a reward, we both owe A huge favor from you!”

"Whether you need a lot of weapons or a lot of resources to fight against the gods in the future, or you want to do other things... you can use this favor. I don't know what's going on with Iron Man, but I am willing to do my best. help you!"

The value of any door is enough for Bruce Wayne to do this.

Tony Stark shrugged. Although he didn't say it directly, his attitude was obviously acquiescence.

"Okay." After Sakata Gintoki thought about it for a moment, he glanced at Su Han and nodded cautiously. With the Speaker of Parliament here, he is not afraid of the two of them defaulting on their debts. After all, the principle of equivalent exchange itself was set by the Speaker of Parliament.

Then, Sakata Gintoki threw the card in his hand in the direction of Bruce Wayne.

Conan pushed up his glasses. After scanning his surroundings, he suddenly discovered something. He stared at Tony Stark with a strange expression, "Why do I think Mr. Stark is very calm now?!"

If you are really paying attention, shouldn't Tony Stark discuss with Bruce Wayne who's side of the random door?

"Maybe it's because Mr. Stark has learned magic and controlled the secret door." Rukia Kuchiki replied faintly.

The secret method door of the ancient master can also do similar things to any door.

Sawada Tsunayoshi was stunned for a moment, nodded thoughtfully, then realized something was wrong and blurted out, "That's not right! If that's the case... Stark shouldn't agree to Batman's proposal at all."

"You have misunderstood one thing," Tony Stark glanced at the ancient wizard and sighed, "As a technological creation, the arbitrary door must contain something beyond imagination that surpasses the technology I currently control. ……science and technology."

"And when I study arbitrary doors, when I study them thoroughly, what I gain in the end is definitely not just the special technology of traveling through time and space! To be precise, the final harvest... should make the technology tree under my control rise in an all-round way."

"...Is this so?" Busujima Yaozi was a little surprised, but also a little confused.

"Actually, it's quite normal," Yuki Asuna stuck out her tongue, "In our world, there used to be two superpowers who were fighting each other and competing to land on the moon."

"Although the development of aviation technology is generally very costly! But the improvement of aviation technology will bring about the improvement of all technology chains..."

"Of course...then something happened to a country, and the progress of aviation was greatly reduced."

Yuki Asuna smiled bitterly, feeling quite regretful.

Liu Peiqiang looked at Tony Stark and Bruce Wayne from time to time, and he was actually very moved by them. But in the end, he said nothing.

His world is still digesting the technology it obtained from Tony Stark and Bruce Wayne... It is difficult to free up his mind to do other things.

After all, Liu Peiqiang is not a scientist after all, nor is he a bad scientist like Batman or Iron Man, who can defeat an entire team of top scientists by himself.

The scientific team standing behind him is thinking about the continuation of mankind, not the technological explosion in a short period of time... They have their own tendencies in the research of technology.

Su Han glanced at the people below with an inexplicable expression, and he naturally obtained the Any Door.

"A prop from the Doraemon world?" Su Han said to himself in his heart. He was actually a little surprised by this.
