The corners of Suning's mouth twitched, this is not the same painting style he imagined?!

However, after thinking about it, immortals, the road of immortality is not chilling, and scientific cultivation of immortals is also cultivation of immortals, maybe it will be faster.

Slowly descending the mountain, since then the city has more legends of scientific immortal cultivators.

The immortals stepped into the valley of the sky, and the clouds and mist were purple and breathy.

Looking at the one hundred and zero major arrays below, three hundred and sixty-five heavy auxiliary arrays, three thousand dark arrays, and eighty thousand life and death cycles, Luo Feng nodded with satisfaction, and in the days when he was away, he did not let go of his homework.

Compared to the defense when he left, it has increased several times.

But this leads to another problem, there is no key to go home!

The formation of Tianyun Valley was changed by the demon in a variety of ways, and all kinds of strange settings emerged in an endless stream, and even Luo Feng, the master of Tianyun Valley, could not recognize it.

"This kind of magic transformation ability, why is it so familiar?!"

Luo Feng stood in the air, staring at the clouds and floating, lost in thought

Now he has two choices, one is to directly and violently demolish and relocate, which is called a force to break ten thousand laws; The other is to crack slowly, which is time-consuming.

sighed, how can you say that it is your own thing, you can't go into the house, so you will smash the house.

Ten fingers danced, according to the Shangqing formation set up that year, the dragon and tiger ciphertext, gradually revealed.

The original goose egg-like transparent and crystalline mountain protection array showed faint ripples because of the guidance of the immortals, like lotus flowers blooming on the surface of the lake.

It looks beautiful, but Luo Feng's brows are getting deeper and deeper.

Which melon baby is this, the system designed?!

In a modern villa in the valley, a girl with long black and bright hair put down the fierce game console in her hand, tilted her head, looked outside, and wondered: "What?!" ”

"Which melon baby doesn't knock on the door before coming in?!"

The formation system in front of him, from the eyes of the immortals, is naturally seen through at a glance, but when combined, it has unexpected uses.

It's like words and brain teasers, individual words can be understood, combined, what the hell?!

Luo Feng's face became darker and darker, and finally he snorted coldly and slapped it down!

In an instant, the formation fluctuated again and again, and even the valley trembled.

The goose-egg-like mountain protection array shattered, like a scattered glass on the ground.

Dressed very casually in the valley, the eighteen-year-old girl's face suddenly changed, the sunglasses on the bridge of her nose leaned to the side, and murmured, "Oh no! ”

"Uncle Zheng seems to have explained, the mountain protection array can't be broken, there will be big problems."

"Questions?! What the hell is the problem?! ”

The girl held her chin and scratched her long messy hair vigorously, thinking seriously.

But, really, really, I can't remember it for a while.

Every once in a while, she forgets something.

In addition to acquaintances, such as Uncle Feng, Uncle Zheng, Grandpa Jingtian, Xu San, Xu Si...... and someone who seems to have known each other for a long time, but can't find it.

While the girl was thinking, the automatic defense system in the valley activated.

Unfolding the equipment, laying the cables, and the missiles are erected, and the coherent actions are completed in one go, fully automatically, without manual labor.

Three red, iron-clad things ejected from an underground base, and at a speed of 900m/s, they smashed straight into Luo Feng's face, blooming into a most gorgeous flower.

The smoke cleared, and Luo Feng walked out of the clouds with a black face.

Perfectly verified the law of smoke and no injury, the corners of his mouth twitched, he didn't want to pay attention to anything else, and stepped out to the source of the missile, the underground base of the Heavenly Valley.

At a glance, they are all the most normal machinery, the most normal bazooka, the most normal Gatling, the most normal depleted uranium bombs......

Most normal ...... The most normal Nima!

Luo Feng came to the end of the underground base, a small room, which contained various operating tables, and a document next to the desk.

There are six large characters written on it, the principle of nuclear bomb design.

Luo Feng's hand trembled slightly, and then opened the first page.

Principle: The nuclear bomb uses fissile elements for chain reaction, and the lost mass is based on the mass-energy equation: E=MC2. A weapon that is transformed into energy in the form of a shock wave, radiation, etc., and is released in a few millionths of a second, thereby causing great damage, and below, we will detail the design process of a nuclear bomb.

…………

Page II.

+ Absorption (INL), the absorption reaction is that the neutrons are absorbed by the atomic nucleus, producing an unstable composite nucleus, by emitting various substances such as: γ, α, hydrogen ions, etc. to consume excess energy to return to the ground state, there is a class of elements that have a high probability of splitting into several smaller nuclei after absorbing low-energy neutrons, and release more than 2 neutrons, triggering a new round of fission reaction, the reaction formula is:

…………

Page 3.

Nuclear fission reactions, such as:

235U10n—→141Ba92Kr310n energy

235U10n—→103Mo131Sn210n energy

…………

On the boundary plane between the nuclear fuel and the reflector layer, there must be an equal neutron flux and an equal neutron leakage

……

When t=0, the density is, the length is l, the mass is m, and the explosive with the detonation velocity D is uniformly detonated at the periphery, and when t=l/d, the detonation wave reaches the surface of the reflective layer M......

The velocity of the particle u satisfies the relation......

Luo Feng's face was expressionless, and he turned the plan to the last page with emotion.

The parameters are as follows......

Looking at the principles designed above, although Luo Feng did not learn professional knowledge, he only understood a little bit.

But with the keen sixth sense of the immortal, this plan seems to work and can be realized.

I don't know how many times I've sighed today, Luo Feng felt for the first time that this kind of behavior was too stable?!!

Tick, tick......

Suddenly, two electronic bodies, a heavily armed girl, holding a shovel, cowered forward and walked into the room.

When I saw Luo Feng for the first time, I was stunned for a moment, and then shouted in surprise: "Uncle Luo, why are you?!" ”

Luo Feng looked back, waved his big hand, and removed the girl's anti-poison, waterproof and fireproof mask, revealing a delicate and familiar face.

"Girl, long time no see."

Luo Feng showed a gentle smile and beckoned to Luo Yuan.

Luo Yuan thought about it, then his eyes lit up, and he reacted: "Uncle Feng, are you back?!" ”

Before leaving this realm, Luo Feng left behind a puppet, with low intelligence, and compared to the robot, his appearance was exactly the same as Luo Feng.

In order to distinguish between Luo Feng and it, Luo Feng asked Luo Yuan to call the puppet Uncle Luo.

Luo Feng gestured, and then took a shot into the void with his hand, bringing back the puppet body that was busy buying game products thousands of miles away.

Luo Yuan stepped forward and surrounded the puppet and Luo Feng to knock left and right, looking excited.

Luo Feng touched Luo Yuan's head and said with a smile: "Let's talk about it when we go out, this is not the place to talk." ”

Luo Yuan nodded, adjusted the button, and one side of the elevator appeared.

Luo Feng followed, casually explained the design principle of the nuclear bomb, copied it, and stuffed it into the space.

This thing, you can test it back to the flood wilderness, maybe it will succeed and develop a version of the fairy road.

A nuclear bomb can't blow up Daluo, but it's still okay to blow up a fish pond in the four seas.
