Qi Zixiao pondered for a moment, thinking about how to tell Ji Chutong, and then said: "Two-way foil is a kind of 'cosmic law weapon' developed on the technological side based on these theories."

"To put it simply, it is a dimensionality reduction attack!"

"Execute dimensionality reduction on everything in three dimensions and bring it to two dimensions! This is two-dimensional foil..."

"To put it simply, it is to turn a three-dimensional object into a flat surface and make it into a painting!"

"this···"

Ji Chutong showed a shocked face. These thoughts made her a little creepy. Dimensionality reduction attack, turning the original three-dimensional world into a picture?

Turn a person into a picture on a piece of paper, leaving only a flat surface?!

This is so scary.

But at the same time, she felt it was impossible: "I can probably understand what you mean, but taking humans as an example, as a three-dimensional existence with a substantial body, how can it be possible to be knocked back to a flat, two-dimensional body?"

"If it's in a divine soul state, it's possible."

Ji Chutong thought about it and felt that it was not that simple. She had considered three-dimensional and two-dimensional things several times, but it was understandable.

But how can we change people from three dimensions to two dimensions? Even though she has understood many Tao principles and is an innate Tao body, she still has no clue.

"That's exactly what's confusing me right now."

Qi Zixiao sighed: "There is another saying on the technology side - conservation of energy."

"The body already has an entity and is a three-dimensional product. It is indeed difficult to make it two-dimensional in an instant."

"But at least the idea is here. In other words, the reason why we find it difficult is that our current understanding of Tao and the laws of the universe is not enough."

"Because of this, I hope you will not start retreating for the time being, but study two-way foil with me."

"If we can really get it out, we will have a brand new invincibility technique!"

"In comparison, even those true immortals and even heavenly immortals may not have seen such invincible techniques. Once they are attacked, it will be difficult for the immortals to save them!"

“···”

Ji Chutong was silent for a moment and then nodded slowly: "It's not impossible. From what you said, if this two-way foil can really be developed, it will definitely become an extremely terrifying invincibility technique."

"But before that, we all need to think more..."

"Yeah." Qi Zixiao agreed.

It is indeed difficult.

The reason why Artificial Sun Boxing could be developed so easily is because Qi Zixiao obtained various materials such as hydrogen bombs and artificial suns from the earth.

However, two-way foil is an 'imagination' in science fiction novels. The theory is also very vague, and there is no relevant information. Everything can only be started from scratch.

In other words...

Create invincibility through imagination.

This was also the reason why she told Ji Chutong about the matter. If possible, it would be best to develop it by herself. However, at present, the 'two-way foil' is beyond Qi Zixiao's ability. If they work together to develop it, the success rate will be higher.

"Tell me more about the positioning and division of two-dimensional and three-dimensional, as well as various details." Ji Chutong muttered: "I still know too little. If I can understand more clearly, I may have some ideas..."

"good!"

Qi Zixiao immediately opened his mouth and told everything he knew.

Ji Chutong listened and expressed his opinions and suggestions, but until it got dark or even dawned the next day, he still had no perfect ideas.

The two of them sat cross-legged opposite each other, both thinking hard.

From time to time, some people put forward some suggestions and ideas, but they were quickly rejected...

This is a brainstorm.

Once they successfully collide with invincible spells such as two-way foil, they will be able to add an almost perfect trump card to the two of them.

But it is not easy to succeed, it is extremely difficult.

During this process, Sister Ah Wu was not idle and communicated with Qi Zixiao from time to time. Unfortunately, she did not have any good ideas in a short period of time.

······

"This is the Great Qin Immortal Dynasty, or the palace of Immortal Qin."

Lin Fan 'logged in' to his account and played Lin Zixiao's photo, without much surprise in his expression.

"Sure enough, have you come to the First Emperor?"

Before he could think about it, Lin Zixiao said again: "In order not to be noticed, I turned into myself. You should be quite used to it, right?"

Looking at 'Qi Zixiao' in the image, the corners of Lin Fan's mouth twitched slightly.

"Well, I'm used to it, I'm quite used to it, but..."

"Forehead···"

"Forget it, don't worry about these details, I have something big to tell you. What do you think the First Emperor is going to do?"

"He wants to reinvent reincarnation!!!"

"Moreover, the empress also found two levels of 'fragments' from the eighteenth level of hell in Kunlun, and it is even suspected that there is a ghost, the foundation of heaven!"

"I once asked him why he was so obsessed with reincarnation, and the answer he got was..."

"He asked you and me to live here. I think it's really good. At least it's safer than wandering outside."

"Whether you want to stay for a long time depends on your thoughts."

"But... through communicating with him, I thought of another thing."

"Extremely important!"

In the image, Lin Zixiao's face is serious and dignified: "The foundation of heaven!"

"In the age of the heavens and the worlds, the foundation of the heavenly ways that has been revealed is close to twenty, and it is said that most of them are obtained from the abyss of the worlds."

"And we have now determined that the Abyss of All Realms is the future Kunlun. So can we think that the foundation of heaven discovered in the Abyss of All Realms by later generations is now located in Kunlun?!"

"Um?!"

After hearing Lin Zixiao's guess, Lin Fan suddenly stared and said to himself in shock: "This is really possible!"

"If so!"

Lin Zixiao's words continued, and she whispered: "If this is the case, can we find a way to obtain as many foundations of heaven as possible?"

"Even if we can't get it ourselves, what if we give it to the Empress and the others, or to the students and friends on the other side of the earth?"

"As long as they don't return to Earth and don't communicate with Heaven, there won't be such huge energy fluctuations and they won't be discovered by many 'immortals'."

"This way, they will have enough time to grow..."

"But before that, we need to figure out where those foundations of heaven come from!"

"After all, at present, we only know that the 'immortal' belonging to Ji Chutong came from the Silent Valley in the abyss of all realms."

"By comparing the maps, we may be able to find out where the Silent Valley is, but we don't know where the other Taiji came from."

"When we return to the heavens and worlds, you and I may be able to put more effort and thought into this matter."

"Besides, let's break through as soon as possible."

"See you later."

Lin Zixiao in the image waved, and soon the screen came into view, but Lin Fan did not calm down for a long time, with a look of shock and hesitation on his face.

"Maybe... it's really possible?"

"If it can be like this, if it can be like this..."

"Whether the power of time correction exists, I can't make a conclusion yet, but judging from the current situation that my saint and I share the same foundation of heaven, even if the power of correction exists, it must be different from what we currently know.

.”

"so···"

“It should be feasible!”

"Once successful, perhaps, I will be able to collect more than ten foundations of heavenly ways!!!"

"Judging from the experience on the Abyss of All Realms, the Foundation of Heavenly Dao will selectively choose its 'host', but we don't know what the situation is now."

"If it can be obtained by one person, can I obtain more than ten pieces of the foundation of heaven alone?"

"If that's the case, I can indeed be called a 'person who deserves disaster' or something, right?"

"Hey, wait, there's another question."

"That is, when the people in the heavens and the worlds entered the abyss of the world, they gained the foundation of the heavenly way."

"If it were earlier than now, it would be feasible, but if the world of cultivation gradually evolves into the world of heaven and earth, it would not be so wonderful."

"...But no matter what, it's worth a try. Next time you go there, try to compare Kunlun and the Abyss of All Realms, and try to find the current location of the Silent Valley, and then..."

What to do next?

Lin Fan frowned slightly.
To be continued...
