Plasma grenade.

Lei Jun could tell from the embarrassment and confusion of the two professors' faces that they knew nothing about the so-called plasma grenade, which made him even more interested in the unsightly young man in front of him. He nodded and said, "Then you can explain the difference between plasma grenade and plasma landmine!"

The young man snapped his fingers and said with a smile: "Literally, the difference lies in grenades and landmines. I believe Riesling should know the difference between these two weapons very well."

Lei Jun said slowly: "These are two completely different weapons. Landmines are passive defensive weapons. They can only be detonated after the enemy is actively approaching. Grenades are much more flexible, but their power is definitely not as powerful as mines."

"Yes, the advantage of grenades lies in their flexibility and convenience. The biggest feature of plasma grenades is that they are very small, and they require much less plasma states, so stability is easier to achieve. As for power, it is simpler. Since the mass of a single unit cannot reach the level of plasma mines, then use quantity to win!" The young man talked happily and seemed very confident.

"Good cc!" Lei Jun's face was shining with his face, swept away the haze just now, and laughed loudly: "Very good! It can not only solve the problem of low power, but also solve the biggest defect of instability. This is a very good idea!"

"The power is low and you can indeed replace it with quantity, but how do you plan to trigger the explosion!" One of the professors stared at the young man with a pair of turbid but divine eyes. He seemed to be uncomfortable with the young man's deliberate favor to Lei Jun, and he had a little bit of a difficult point in his words.

Another professor also asked: "The plasma state in the plasma grenade is too rare and cannot reach the concentration of the explosion at all. This is not an ordinary grenade. You can explode by pulling off the fuse and throwing it out!"

The young man smiled calmly and said, "I have thought of this problem. The solution is also very simple, so just increase the plasma concentration manually and let the grenade reach the critical point of explosion."

"Artificially increasing the concentration?" Both professors were confused.

The young man spread his hands and said seriously: "It's very simple. As long as you output a certain amount of sword energy or magic power in the plasma grenade, you can reach the critical point of explosion. I have been experimenting with this many times."

This most critical issue failed to stump the young man. The two professors looked at each other, a little embarrassed, and didn't know what to say, so they could only stutter: "But, but there is no such plasma grenade exchange drawing at the altar. I don't believe that the Third Civilization would not have such an easy thing, and there must be some loopholes."

The young man shook his head and said loudly: "Dear professors, we are in the end of the world, not the simple third mechanical civilization! Everyone can completely let go of their minds. I guess the third civilization at that time had extremely high technology and individual strength, so it was not that they could not imagine the creation of plasma grenades, but that they themselves did not have enough magic fighting energy and sword energy, but that we are different. We have mixed products of multiple civilizations, and we are stronger than them!"

"Well said it! We will be stronger than ancient civilizations. They cannot resist the invasion of dark creatures, so we can!" Lei Jun seemed extremely happy and asked the young man loudly: "What's your name?"

The young man replied respectfully: "My name is Lu Renyi. As I said just now, I am a senior electromagnetic theorist."

"How could your level improve so quickly? I remember you are just the assistant of the two professors."

The young man smiled and said, "I just took the liberty to learn the electromagnetic books you exchanged for Riesling while the two professors were resting. Perhaps my understanding was stronger, and I was accidentally promoted to advanced."

The two professors were certainly a little angry, but the cold eyes that Lei Jun glanced intentionally or unintentionally made them feel as if they were in an ice cellar. They could no longer care about being angry. They knew very well that once they lost Lei Jun's protection, they would judge their strength. What would happen in this era where monsters were all over the ground.

"Very good. From now on, you will be responsible for all the research equipment and materials here! My territory does not require useless waste, as for you two." Lei Jun looked at the two professors, frowned, as if he was a little uncertain about how to deal with it.

Lu Renyi cleared his throat and said, "Risling, even if I were asked to take responsibility, I still need someone to help me. Electromagnetic technology is different from magical civilizations, and only those who are proficient in this can do it."

Lei Jun did not comment, thought for a while, and nodded, "Then let it go. In short, I need to make the most plasma grenades for me in one week, no, within three days!"

Lu Renyi was slightly surprised and asked tentatively: "Do you want to deal with Thunder King Spider?"

Lei Jun sneered: "That's natural. I heard that Haoren defeated the Fire King Spider without damage. Humph, did he think he could be the strongest man in Jinling City? When the plasma grenade is mass-produced, I will let him know the power of electromagnetic technology!"

Lu Renyi hesitated and said, "I forgot to explain just now that the plasma grenade needs to instill the magic power of the fighting spirit or sword energy into it before it can be detonated."

"You have already mentioned this point just now. Is there any problem?" Lei Jun was eyeing him.

Lu Renyi swallowed hard and whispered: "What I want to add is that the amount of fighting energy that needs to be injected is also limited. According to my test, at least people with combat power of more than 3,000 will have the concentration of fighting energy or magic power to reach the critical point of opening the explosion."

"Three thousand combat powers!"

"And because the amount consumed each time is huge, even in the peak state, the number of plasma grenades that can be thrown is quite limited. According to my estimate, under five thousand combat power, the maximum amount of plasma grenades that can be thrown is only three to four, and then the combat power will be lost due to exhaustion of strength. Those with more than five thousand combat power can maintain about six to eight grenades."

Lei Jun narrowed his eyes and asked, "Then tell me, how powerful is the plasma grenade? What kind of skill is equivalent to."

"It's much higher than the silver skill, but it's slightly lower than the golden skill." Lu Renyi answered with certainty.

Lei Jun closed his eyes and pondered that after the battle of the spider behind the ice, he also came to a conclusion similar to that of Haoren. It was difficult to compete with these spiders simply by relying on silver skills. Although it was difficult to popularize the golden skills, it seemed that the plasma grenade could do this.

Lei Jun pondered to himself: "It should be impossible to defeat the Thunder King Spider by relying on combat power. So if you use plasma grenade as a weapon, let enough people enter the dungeon and rely on the number to crush the Thunder King Spider, you may be able to succeed."

Lu Renyi was slightly stunned and said hesitantly: "It is feasible in theory, but I think it is not that simple in fact. The number of people that the copy can accommodate is limited. I think this may also be a limit to us humans. Plasma grenades are just an auxiliary to surprise attacks. As long as they can remove one-tenth of the boss's blood, it will be a great victory."

In fact, in Lu Renyi's initial vision, plasma grenades were popularized as an attack method that was higher than silver skills. After all, in Jinling City, the number of people at the stage of combat power of 3,000 to 5,000 is increasing, but the gold skills are obviously unable to keep up with this number of growth.

When the silver skill is increasingly unable to cope with the ever-increasing monsters, the plasma grenade will play a big role at critical moments, but it is just an auxiliary. The plasma grenade will definitely not be used as the main attack method. Lu Renyi is very clear about this.

Lei Jun hummed lightly: "I will arrange this myself, you don't need to worry about it anymore!"

Lu Renyi could almost guess how Lei Jun wanted to use plasma grenades to deal with Thunder King Spiders after thinking about it for a moment. For example, let a group of people with three thousand combat power form a team to be cannon fodder. When they use up all the plasma grenades, they will be killed by Thunder King Spiders without any suspense. Then, the second batch of cannon fodder, the third batch, the fourth batch... use the number to kill the Thunder King Spiders!

No, to be more precise, when the Thunder King Spider only has the last little health, Lei Jun will lead the team in person to do the final harvest, and then put all the equipment and skill stones into his pocket.

This is a **naked human bomb, very cruel, but it has to be said to be very effective.

It’s not that no one thought of using the quantity to pass the dungeon. Although the number of people that the dungeon can accommodate at the same time is upper limit, when a team is destroyed, the boss’s health will not be recovered immediately as long as the new team follows up immediately. Although the possibility is that when the boss is in poor condition, he will quickly escape.

However, when facing a Thunder King Spider level, it is even difficult for ordinary silver skills to cause much damage. If you cannot have the power that exceeds the silver-level skills, the number will be meaningless.

"Human Bomb, Damn, I seem to have done something stupid!" Lu Renyi sat dejectedly on the ground.

The two old professors looked at each other, and one of them went straight forward, patted his shoulder, and sighed: "Young man, you are still too young after all. Lei Jun is an unscrupulous person. You should have thought of this long ago."

"Then should I make this plasma grenade?"

“Do we have a choice?”

...

When Haoren sneaked into Lei Jun's defense zone, he found that it was quieter than before. It seemed that many people quietly left this safe defense zone and went to seek other shelters.

After asking a few people, Haoren was speechless. Only then did he learn that Lei Jun was actually buying and even pursuing energy crystals at a very low price, preparing to make electromagnetic weapons to prepare for the next Thunder King Spider Battle.

Haoren could not evaluate Lei Jun's behavior. Although Lei Jun's name is very reasonable and is for the safety of the entire Jinling City, more and more people are resentful of him.
