Li Rui didn't know exactly what happened to Hexi's test against Angel Yan, and all he knew was what Hexi wanted to talk to him about. In other cases, Hexu didn't want to say it, and he couldn't force it.

Now he was looking at the bullet in his hand with excitement.

……

"God Killer Four?" Qi Lin looked at the bullets on the table with some disagreement.

The shape of this bullet is somewhat unusual, the warhead is not sharp, but smooth, like a mirror, as if there are no folds.

If Li Rui hadn't told her that it was a bullet, she might have thought it was an ornament.

The corners of Li Rui's mouth rose slightly, he liked to see Qi Lin's surprised little expression, no matter how many times he watched it, it was not enough.

This bullet is a new type of god-killing martial arts that he made based on the god-killing power of the Norstar God of War based on strong interactions, and it can effectively cause extremely considerable damage to gods, including the four generations of gods.

The strong interaction has been mentioned before, so it will not be repeated. However, in order to shrink this technology to a warhead and prepare sufficient materials for the first step of the chain reaction, Li Rui did waste a lot of effort.

If he hadn't come up with the low-dimensional particle unfolding technique, he wouldn't have been able to do it at all.

"Don't underestimate such a small warhead, its cost is equivalent to that of a second-generation super soldier. And it's also disposable, non-recyclable. ”

Qi Lin was startled and looked up at him in surprise.

Li Rui solemnly told her about the power of this God-killing No. 4 bullet.

"Once this warhead leaks out, it will be a disaster for the super soldiers of the entire known universe." As he spoke, Li Rui took out two more bullets and put them on the table: "At present, I have only made these three, so we must use them carefully." ”

The reason why it directly crossed the so-called God-Killing No. 2 and No. 3 and named God-Killing No. 4 was because of its ability to effectively kill the four generations of gods.

"What about yourself?" Qi Lin carefully put away the bullet and asked.

Li Rui stretched out his hand to draw a semicircle, and with his movements, a flying knife appeared in the air.

These knives are pitch black, with a spherical core in the middle of the blade, glowing with a golden-red glow.

Throwing knives are not identical in appearance and seem to be able to be combined with each other.

What was given to Qi Lin was a god-killing armor-piercing bullet, and Li Rui naturally wouldn't forget to equip himself.

The last time he dealt a blow to Morgana, he relied mainly on the proton computer on his armguard. In fact, these proton computers are not weapons, but peripherals of the mother box, which are used to support the operation of the mother box, and attacking Morgana is only a last resort.

Now that this god-killing power based on strong interaction has been weaponized, Li Rui has made it into thirty-six combined flying knives, which integrate attack and defense, which is convenient and powerful.

This is considering that his own combat style mainly relies on the power of time and space, and the miniaturized, easy-to-handle weapon of the throwing knife is the best partner.

Moreover, the computing core in the middle of the flying knife is completely composed of particle computers, and each flying knife has powerful computing power, which can not only be charged like a meteorite, but also can be used to solve and strike at the target.

Because of the use of stellar energy technology based on the sun and transformers, the attack power of these throwing knives is also quite amazing, and the maximum power can even penetrate the planet.

Coupled with its combined attack ability, it is easy to destroy stars.

Qi Lin picked up one and looked at it for a while, and found that the flying knife itself was not black, but only because of the diffuse reflection generated by the runes that had been miniaturized to the extreme, causing the flying knife to look like black.

While weighing the weight of the flying knife, Qi Lin asked, "You've been researching the upgrade of the Divine Killing Martial Artist recently?" ”

"This is just one of them, and of course there are other projects. In addition, there are other projects in the scientific research department, and some results have also been produced, and I am staring at them. ”

As he spoke, Li Rui turned on the projection in front of him.

The first one that appeared seemed to be an engine, but the three-dimensional projection couldn't tell the specific size, but her intuition told Qi Lin that it must be a very important achievement to be put in the first place by Li Rui.

"Well, this is an antimatter engine developed by the space power group of our Ministry of Science. It was developed by Huang Dejian, an expert in space dynamics of our Donglong. ”

We all know that annihilation occurs when antimatter and matter meet, in which the mass of positive and antimatter is converted into energy. According to Einstein's mass-energy formula E=mc2, a huge amount of energy will be released, which is the most efficient way to obtain energy in the physical reactions known so far.

The high efficiency of the antimatter engine can be demonstrated by comparing the heat released per kilogram of fuel: in general, an ideal hydroxide reaction can produce 1×10 to the 4th kilojoule, nuclear fission to the 10th × 10, fusion to the 11th × 10, and antimatter annihilation to produce 9×10 to the 13th kilojoules, which is 10 billion times that of hydroxide reactions and 300 times that of the solar core thermonuclear reaction.

As a result, the specific impulse of such a spacecraft will be the highest, and the thrust-to-weight ratio will probably be the highest. Ideally, the annihilation of antimatter and positive matter the size of an aspirin would produce enough energy to send a spaceship hundreds of light-years on a cruise. Just a few milligrams of antimatter can allow a huge spacecraft to travel within the solar system, even to Proxima Centauri for only a few kilograms, which shows how efficient it is.

In addition, the antimatter engine has another benefit: the annihilation of antimatter can occur spontaneously and does not require many conditions like a nuclear reaction in a nuclear engine, so there is no need for a large reactor and the weight of the ship can be reduced.

In general, when choosing antimatter engine fuels, protons and antiprotons are usually chosen, because they do not immediately produce gamma rays when they annihilate, but produce 3 to 7 mesons, usually 3 charged mesons and 2 neutral mesons. Neutral mesons are converted into high-energy gamma rays almost immediately, while charged mesons have a lifetime of 28 nanoseconds, but because they move at 94% of the speed of light, their half-lives are extended to 70 nanoseconds and advance an average of 24 meters before decay is complete. In this way, we can use the magnetic field to control their direction and let them interact with the propellant.

Based on this principle, there are four main design schemes for antimatter engines, listed here from low to high in terms of specific impulse: solid core, gas core, plasma core, and particle beam core.

Originally, if there was no gluttonous tide captured by Qi Lin, the scientific research team could at most advance the technology to the third stage, but after learning from the gluttonous tide, it directly advanced to the fourth stage.

What is the effect? Judging from the data, the specific impulse produced by the solid core can only reach 1,000 seconds, the gas core can reach 2,500 seconds, the plasma core can reach between 5,000 and 100,000 seconds, but the particle beam core can reach an astonishing 10 million seconds, which is a hundred times that of the third stage! Moreover, the particle beam core to the engine does not require propellant like the previous three, which can further reduce the load on the ship.

"The increase in power means that our conventional ships can be built larger, equipped with more functional components, and can be used for deeper space exploration without relying on space jumps." Li Rui concluded.

"This is really our own scientific research team's research, you didn't give it a hang?"

Li Rui's face turned dark, why did Qi Lin start to suspect that he was hanging?

Well, he admits that he is indeed a hanger. But the antimatter engine is not really the product of his hanging.

Because, the refinement of antimatter on Earth has been realized at the end of the last century, and the difficulty is only in large-scale production and storage.

But with the gluttonous tide as a reference, the difficulty of overcoming these two problems is greatly reduced.

"Okay, I see." As soon as she saw the change in Li Rui's expression, Qi Lin understood, and her eyes flickered to show that she understood.

However, this is a good thing, which shows that the alliance and the scientific research team have also begun to break away from Li Rui's help and have the ability to conduct independent research.

In fact, the achievements of the alliance are not only the antimatter engine, with Li Rui's introduction one by one, as many as 30 scientific research achievements are displayed in front of Qi Lin one by one......
