"Yes, there are two modes of attack of the main gun, namely charging mode and reloading mode, and there are four levels of charging mode, which is only the lowest level, which requires ten seconds of energy storage, and you have also seen the power."

"The second gear is for one minute, the third is for 10 minutes, and the last is for 15 minutes. However, the last gear is not a last resort, and it cannot be used, because then the main body of the tank will also be destroyed, which is a trick to injure the enemy by 1,000 and damage 800. ”

Understood, to put it bluntly, this is the trick to end up together.

Fifteen minutes of energy storage time is not particularly long, and listening to the introduction of Valen Wind Blade, it is no longer important whether it can be released or not, the important thing is to destroy the tank, not to fall into the hands of the enemy, and to others as trophies to pull back.

At the same time of self-destruction, if you can pull a few cushions along the way, it is of course an excellent thing.

"The charging mode is not the main means of attack, after all, this attack mode requires a lot of mana, and naturally it will consume a lot of magic crystals, although our underground factory has a large amount of mana, it can be allocated to this, but it can be saved or saved."

Valen's words won Chen Nai's heart, yes, his own things, can he save or have to be saved, is this huge family so easy to come by?

If it weren't for Chen Nai's forging fashion suits and saving up little by little, how could it be so easy to develop, these are all hard-earned money.

From the meaning of Valen's words, it is not difficult to hear that he regards this place as his home, and with a sense of belonging, he will think about it like this, which is definitely a good thing.

"So, what's the main means of attack?"

"The main attack method is reload mode, switch attack mode!"

With a bang, the cannon shot a pitch-black spherical object, which was ejected far away, and then exploded when it landed on the ground, producing an explosion.

Chen Nai is no stranger to this kind of explosion, because he has used it before, this is a goblin bomb.

Compared with the magic crystal, the cost of goblin bombs is much lower, and the underground factory has its own set of very mature production chains, which can produce tens of thousands of goblin bombs at one time.

Chen Nai had Ospark produce a few times before, but now the underground factory has hoarded hundreds of thousands of goblin bombs, some of which have gone into Chen Nai's backpack, but more of them are still idle, and now they come in handy.

Although in terms of power, the power of the goblin bomb is difficult to compare with the kind of attack just now, but its advantages are that it is large in number, low in cost, and fast in reloading, it can be reloaded in two to three seconds, and it can be launched by pressing the launch button.

Moreover, it is still parabolic, and at some point it can also cross the obstacle and directly attack the enemy's logistics troops, and it is not impossible to destroy the base camp by smashing the Yellow Dragon.

However, Chen Nai has some other ideas, the power of this bomb is not impossible to improve, right, research and improve a new formula!

The raw materials of these goblin bombs are still black powder, which belongs to the level of homemade bombs, and there is still a lot of room for improvement in power.

And in the 21st century, there are many types of bombs, such as incendiary bombs, poison gas bombs......

Well, Chen Nai held his chin and thought about it seriously, this idea is feasible, but it needs researchers.

"What has Carter been doing lately?"

If it weren't for such a thing today, Chen Nai would have forgotten that he still had a pharmacist.

In order to fill the number of goblins before, Chen Nai abducted him along with those goblin assistants.

After turning around, Chen Nai just asked him to develop a hair growth potion, and then gave him some potion formulas and left him alone.

Now Chen Nai thinks that he can give full play to his expertise, the goblin is good at science and technology, which belongs to the physical technology side.

Then Carter belongs to the chemical drug aspect, and he can't be allowed to hold on to the medicine all the time, and expand some ideas, so that there will be better development, right?

Let him study some special potions or poison gases, and then reload them into cannonballs to expand the types of cannonballs.

If he can study a doorway, it will open the door to a new world, and he can become a grandmaster-level figure who opens the door to the sect.

It was a very challenging thing for him.

No way, Carter is a layman, his purpose in becoming a pharmacist is very simple, he just wants to make money and make a lot of money.

Now that this goal has basically been achieved, he has a new goal, which is to make a name for himself.

Chen Nai just likes this kind of vulgar person, although it is a little vulgar, but because of this, it is more simple and cute.

"It's still the same, I don't come out of the lab all day, but I was noisy for a while."

"What is he arguing about?"

"Talking about an assistant, he always said that without an assistant, his research progress would be slow. The formulas of the potions you gave him are very difficult to study, and he has been studying them for a long time, and he has only just figured out a little clue. ”

"Oh, he still wants a goblin assistant."

"Yes, he wants it, but you won't give it, and there is no goblin willing to go, so I found him a dozen smart and clever children, help him get started, and learn by the way, although the potion can now be mechanized to produce, but this research still needs people after all."

In this regard, Qinhaiyan is deeply influenced by Chen Nai and attaches special importance to researchers.

"Well, you're doing a good job, but if you want to train a pharmacist, you can't do it in a short time."

"This cat master can rest assured, I found those assistants for him, they are all very talented in this area, and they will study hard without the supervision of others, this period of time has been quite effective, and in another three or five years, you can go to the exam as a trainee pharmacist."

Qin Haiyan was selected from those poor believers, each of whom had a very good intelligence, and when they heard that pharmacists were such an iron job as a pharmacist, they even broke their heads, and they didn't need to be supervised by others, so they worked hard to study.

If they can really become pharmacists, then they will have no worries about food and clothing in the future, and they can also let their families live a better life.

So no matter how hard and tiring the assistant's work is, they will grit their teeth and persevere, and study hard with 1,000 percent of their energy.
