"I don't know how long we can hide it. Maybe one day we will be exposed sooner or later. If we can break through to the level of Xuanxian or even Jinxian before being exposed, we should have enough confidence."

"If I could hide until Daluo Jinxian..."

"You and I can truly return!"

"I always feel that it won't be that simple." Qi Zixiao slowly shook his head: "Retreat, practice, and breakthrough are all inevitable."

"But it's very likely that things won't go so smoothly for us. To take precautions, I want to... develop a new invincibility technique!"

"Newly developed invincibility technique?"

Ji Chutong was startled, and then showed a wry smile: "You are indeed very strong, and your lethality at the same level is far greater than mine, but invincibility is not that easy to develop and create."

"The time required is very long, often thousands, tens of thousands of years, or even longer."

"Relatively speaking, with the foundation of Heavenly Dao, our breakthrough will be smoother and the time will be shorter."

By the way, I’m using the Zhuishu app recently. [app] caches books for reading and reads aloud offline!

The so-called invincibility is not a certain 'realm' division in magic, but a 'general name' for all super powerful magic and magical powers.

Generally speaking, there are several additional conditions for being called an invincible spell.

for example···

In terms of attack, the invincible technique must be able to kill the enemy in a larger realm, or even two realms! Such an amazing technique can naturally be called an invincible technique.

If it is defense and speed invincibility, the most basic thing is to save your life when being chased by strong men who are two or more realms higher than you!

What is invincible?

It’s not about being invincible in the same realm, it’s about having an invincible posture and fighting across big realms. This is the so-called invincibility technique!

However, even if you think about it with your toes, you will know how difficult it is to develop, create, and create this kind of invincibility technique from scratch.

The hardships involved are enough to make countless people despair.

Therefore, everyone knows that the invincibility technique is powerful, and even mastering one or two of them at will is enough to instantly increase his combat power by several levels.

But this thing is difficult to practice!

Intensity and difficulty of training complement each other!

Learning other people's invincibility skills is like this, let alone developing it yourself? That is even more difficult than climbing to the sky, so Ji Chutong believes that this is very unrealistic.

Although invincibility is indeed very helpful, at least it is currently unrealistic.

"I know this is extremely difficult."

Qi Zixiao sighed: "But my previous series of invincible techniques such as the Artificial Sun Fist are somewhat ineffective."

"Really speaking, the Artificial Sun Fist series can only be regarded as invincible techniques at Sendai and below stages. Beyond that, it cannot be called invincible."

"So, we urgently need a brand new invincibility technique that can kill the enemy at a critical moment, or an invincibility technique that can give us a glimmer of hope!"

"But it's still difficult, in comparison..."

"I understand your concerns."

"But, I already have an idea, and the next thing to do is to develop it!"

"Got an idea?"

Ji Chutong was shocked.

Invincibility is difficult, but the most difficult thing is actually the idea...

The world of cultivating immortals has been passed down for thousands of years. How many years has it been passed down through all the heavens and worlds? According to Wu Nianxiang, it must have been at least hundreds of millions of years, right?

Over the years, how many kinds of spells and magical powers have been created by countless creatures? There are countless people. Almost all kinds of ideas have been thought of...

It's not that I can't create techniques that others have created, but that almost all feasible ideas have been used.

Therefore, on this basis, develop new ones?

Brainstorming is extremely important, that is, ideas!

Otherwise, what would you develop? Just learn from others. However, public invincibility techniques basically have ways to break them, so they are not considered invincibility techniques.

The new invincibility technique that I thought up by myself... naturally I won't have such worries.

Once you have an idea, you can proceed step by step based on the idea and find ways to 'manifest' it.

The difficult thing is to have a complete idea! It is manifest... Relatively speaking, you can learn from it or 'look up information'.

"What do you think?"

"Two-way foil!" Qi Zixiao narrowed his eyes slightly and responded softly.

This is the inspiration she found from Earth's technology... no, it should be said from the technology side. It is also one of the most powerful weapons on the technology side that she knows so far!

Of course, perhaps in the eyes of people on the technology side, two-way foil is not a weapon, but some kind of efficient 'cleaning tool'?

There must be no technology like two-way foil on the Earth. With the current technological level of the Earth, it is simply impossible to create it. The difference is thousands of miles.

Even this is just an idea.

but···

An idea is an idea, and with the development of science and technology, it will eventually be possible, right?

At least, the weapons Wu Nianxiang brought before can already interfere with cause and effect. They are cause and effect weapons. This is also a high technology that is simply unimaginable for the current earth.

Since causal weapons can appear, why not two-way foils?

When it comes to using the theory of cultivating immortals to develop invincible techniques... Qi Zixiao does not think that he understands 'cultivating immortals' better than many masters of cultivating immortals over the past hundreds of millions of years.

Those invincibility techniques have basically been developed by them.

Do you want to develop it yourself? As Ji Chutong said, it is almost impossible.

But...the technology side is different!

You can definitely work hard in this direction.

Even on the other side of the earth, two-way foil is just an existence in a science fiction novel——

The two-way foil is one of the cosmic law weapons that appeared in "Three-Body III: Death Eternal Life".

First appeared on a spaceship from the singer's "home world".

Two-way foil is specially used to eliminate weak civilizations hidden in star systems with more complex structures.

Therefore, two-way foil is not a weapon for advanced interstellar civilizations, but an efficient cleaning tool. However, its abuse in the universe has greatly accelerated the death of the universe.

Three-dimensional space consists of three dimensions: length, area, and volume. The moment the two-dimensional foil comes into contact with the three-dimensional universe, one of the dimensions will curl up from macro to micro, thus forcing the three-dimensional universe and all matter in it to collapse into the two-dimensional universe.

And "melt" in two-dimensional space into an absolute plane that only exists length and area and is deprived of the concept of volume.

At the same time... it will remain in the 'two-dimensional state' forever!

Originally, Qi Zixiao had never thought about this. She felt that novels were fake and created by people and could not be true.

However, before I knew that the novels and TV series were false, didn’t I also research the true secret of controlling thunder with the divine sword?

Didn't the 'Heaven-Swallowing Demon Technique' and 'Breeding with the Body' that my own dog thief wrote based on the novel were also learned by Uncle Master, Master and the others?

In this case, it proves that some of the ideas in the novel can actually be used.

The appearance of Wu Nianxiang and the others, coupled with the emergence of the 'Law of Cause and Effect' weapon, can also prove this point.

Since it is possible to create weapons with the law of cause and effect, then... it is not impossible for me to cultivate immortality and develop an invincible technique of "law of the universe", right?

After all, before this, it was basically believed that 'cause and effect' was a method of the mysterious side, but now, the technological side can play with cause and effect. There is nothing wrong with me cultivating immortality and playing with a near-perfect 'cosmic law weapon' on the technological side, right?

Qi Zixiao thought clearly.

Ji Chutong was confused. The name made her confused: "Er-directional foil... what is that? Just listening to the name, it is really difficult to understand."

"This is normal."

Qi Zixiao chuckled: "This is the inspiration I found from the technology side, but I only have inspiration at the moment. How to 'materialize' it and successfully create it, but I still need your help, so I will tell you something first.

Let’s talk about some ‘discoveries’ on the technology side.”

"For example, dimensions!"

"On the technology side, space is divided into many dimensions."

"To put it simply, one dimension can be understood as a 'point'."

"And wei is a plane figure, such as two points connected to form a line, or some kind of pattern, but they are all on the same plane, not three-dimensional."

"The third dimension is our current state. You and me, houses, tables, chairs and benches, flowers and plants, all belong to the third dimension."

"The three attributes of length, width and height all exist. We belong to a 'three-dimensional' rather than a flat surface."

Ji Chutong frowned slightly.

She heard these clearly, but as a mysterious being, it was not that simple for her to immediately understand the theories and knowledge of the technological side.

"It's not too obscure. I should be able to understand it after thinking about it a few times." She nodded lightly: "You continue."

"good."
To be continued...
