"Very good!" Emperor Shi Tian was overjoyed and hurriedly said, "So how much can mass production reach?"

"Now there is a lot of steel, there is no shortage of magic water, and there are countless micro-robot craftsmen on the side of the barrage, so the production efficiency is very high. Long Pao Ji thought for a moment and said: "Without affecting other tasks, 1,000 rounds a day, if you stop other projects and go all out to produce this kind of rocket artillery, you can reach a speed of 10,000 rounds per day!

"Haha, Yaslian can't be used as a worker like this. Emperor Shi Tian immediately laughed and said: "Anyway, there are still one or two months before the siege battle, and there can be tens of thousands of rounds of normal production, well, make up a whole number, and find a way to produce 100,000 rounds of rocket artillery." ”

"No problem. Long Pao Ji patted his chest and said: "It can definitely meet the requirements, but, what type of rocket artillery will be produced?"

Hearing this, Emperor Shi Tian also suddenly showed a helpless look, and couldn't help but smile bitterly: "It's also a troublesome matter if there are too many varieties, and it's difficult to choose! But in the case of siege warfare, it is likely that the city wall needs to be cracked, so the earth splitting technique is essential." But this thing is less lethal, more is useless, less is afraid of not enough, trouble!"

"2,000 is enough!" Aladdin interjected, "With the current level of defense, even if the opponent's city wall is reinforced by a magic array, it is unlikely that it will be able to withstand two thousand rounds of third-level earth splitting techniques!"

"In this case, let's build 2,000 Earth-Splitting Rocket Launchers first. Emperor Shi Tian then said: "Then after breaking the city wall, it is time to fight street battles, what is the best spell for street fighting?"

After all, Emperor Shi Tian came from the Nether, and he was not a mage, so he didn't know much about spells, so he could only consult Aladdin, an expert, at this time.

Aladdin thought for a moment, and then said: "There are basically three kinds of castles in the underground world, one is a masonry structure, one is a wooden structure, and the other is a cave structure. The first two explosive techniques with firearms can cause great damage, while the latter ones, the explosive techniques are difficult to work, and they can only use spells such as poison cloud techniques, but they are afraid that they can resist toxins. ”

"Why don't you use a combination of greasy spells and firewall spells?"

"Combining spells?" Emperor Shi couldn't help but ask, "Can these spells still be combined?"

"Of course, the power of the spells after combining them is increased several times. Long Pao Ji said with a smile: "Among the tens of thousands of spells, the reason why we picked out so many is that we fancy that they can be combined with each other to form a combination spell. ”

"What's the combination?" Emperor Shi Tian immediately asked curiously.

"The most famous are the two combinations, the Acid Rain and Thunderclouds, the Fire Wall and the Whole Greasy. Danmaku Ji explained: "The acid rain technique itself is not very lethal, but it can corrode the opponent's metal armor and weapons, but after adding the thundercloud technique, it is completely different." The area covered by acid rain is very large, and the conductivity itself is very good, which makes the lethality and killing range of the thundercloud technique increase exponentially. ”

"And the whole greasy technique is actually to spread a large thick piece of grease on the ground, so that people can step on it, and it is very easy to fall. This is a sluggish secondary spell that is also non-lethal. However, when the grease is ignited by the Fire Wall Technique, it will instantly turn into a large sea of fire, and it will be a sea of fire that continues to burn. Long Pao Ji said with a smile: "The most terrifying thing is that the person who is caught in the sea of fire will flee in panic, but there is still grease under his feet, so it is easy to fall to the ground at this time, roll on the oil, and then he will turn into a humanoid torch." ”

"Wow~" Emperor Shi Tian shuddered just thinking about that situation, and couldn't help but say: "I didn't expect that the combination of two ordinary spells would exert such terrifying lethality." If that's the case, wouldn't the rocket launcher with the combination of the greasy technique and the wall of fire become super incendiary bombs?"

"That's pretty much it, so when attacking the cave, you can use this combination to let the grease run in, and then burn them to death!"

At this time, Aladdin frowned and said: "It's not that simple, the oil released by the whole greasy operation is very viscous and has no fluidity, just like butter." ”

"Then let's just make some flamethrowers!" Long Pao Ji said excitedly: "We have an oil palm banyan tree now, and the annual oil palm fruit is all bright liquid oil, and the combustion is also very good, and it can be used as fuel for flamethrowers." ”

"What are you kidding?" Emperor Shi Tian frowned and said: "The air in the cave itself is not smooth, if you set fire to it with your life, will there still be people alive there? It doesn't matter if the enemy is dead, but what can you do? Do you want to suffocate them to death?"

"This?" Long Pao Ji was stunned for a moment, and then said curtly: "Then why don't you study some breathing masks?"

"Don't bother with that!" Emperor Shi Tian said directly: "If you encounter a battle for the cave, let the crazy iron dog take the lead, the cave man shooter will be behind, the machine gunner, grenades, and rocket artillery will shoot wildly in turn, and I don't believe who can stop it!"

"That's right!" Long Paoji's eyes suddenly lit up, and he immediately said excitedly: "How did I forget? We now have crazy iron dogs as meat shields, these rough-skinned and thick-skinned guys are in front, and ordinary goods can't stop them at all." The guys who are better than them can't stop the powerful firepower output behind them. And the environment of the cave restricts them, and there is no way to bypass the crazy iron dog and attack the caveman directly. So our shooters can output as much as they want, and that's almost invincible!"

"The most important thing is the crazy iron dog, these guys not only have strong combat effectiveness, but also have stronger survivability, three hearts, two brains, and an energy core, even if they destroy half of them, they can still live, and they can be alive again after a few months of going back. Emperor Shi Tian said with emotion: "If we had such a meat shield warrior at that time, how much could we reduce the sacrifice of our companions!"

"I understand, let's go back to drill them, let them understand the true meaning of joint attack and infantry and artillery coordination. Long Pao Ji immediately reassured.

At this time, Aladdin suddenly interjected, "If you want to further reduce casualties, protective and healing spells are essential, so I'll go back and make some of these magic scrolls, I believe they will come in handy during siege battles." ”

"Great!" Emperor Shi Tian immediately said: "Try to build as many as possible, if there is any need to say it quickly, I will try my best to meet it!"

"Can you secondment a few Earth-based monks?" Aladdin said, "They should be able to make Earth-based protective spell scrolls." ”

"No problem, five for you!" Emperor Shi Tian said with some distress.

He was busy moving here every day, and every time the portal was opened, it would consume a lot of mana from the earth monks to transport.

It can be said that each earth monk represents a transportation capacity of thousands of tons, and giving five at a time is equivalent to reducing the transportation capacity of more than 5,000 tons. Emperor Shi Tian was also extremely distressed.

But there is no way to do it, because Emperor Shi Tian knows that it is more important to preserve his elite troops than a little bit of transportation capacity.

What's more, these days, he has been frantically producing cave people, and he has successfully found a few geniuses who can turn into earth cultivators, which has further expanded his monk army, and it doesn't have much impact to take out five.

In the blink of an eye, two months passed in a flash.

On this day, the little angel found the busy Emperor Shi Tian and said to him: "Lord, our siege mission has been released. ”

As he spoke, the little angel raised his hand and waved, and a light curtain opened in front of Emperor Shitian, on which was the information of this mission.

Mission Name: Siege Warfare

The mission grade is bronze

Two days after the mission starts

The mission duration is seven days

Objective: Grey Dwarf Castle

The objective of the mission is to destroy all hostile gray dwarves and take over the castle once and for all

Mission DescriptionMaster Karst Rune is the pride of the Grey Dwarves and is proficient in rune alchemy, rune forging, and rune teaching. He once followed a Protoss angel and became the strongest follower of the other party. But after the death of his master, his soul was devoured by the magic contract, and he was hit hard, and his strength was stagnant at the bronze level forever. He could only wander in the first layer of the underground world, unwilling to be like this forever, and spent decades building a gray dwarf castle, with his 20,000 followers, occupying tens of thousands of kilometers of land around him. And your mission is to find him, kill him, or submit him!

After reading the entire mission description, Emperor Shi Tian was suddenly a little confused, and he couldn't help but ask Xiao Tiandao: "What does this Master Custer's 'Rune Teaching' ability mean?"

"That is to say, he is similar to an instructor, and can quickly teach rune skills to his subordinates. The little angel explained.

"Doesn't that mean that he has a lot of rune alchemists and rune alchemy blacksmiths in his hands?" said Emperor Shi Tian in a daze.

"There must be hundreds or thousands, right?" guessed the little angel.

"Then what kind of equipment can these people make?" Emperor Shi Tian hurriedly asked.

"You can't make it if it's too good, but bronze-level rune alchemy armor weapons should be able to make it. The little angel said.

"So this castle has been around for decades, and with the addition of hundreds of rune alchemists and rune alchemy blacksmiths, does that mean that they have a large number of bronze-level rune alchemy magic equipment?" asked Emperor Shi Tian.

"Yes, almost, one for each person!" the little angel said uncertainly.

"Your uncle~" Emperor Shi Tian was so angry that he burst into foul language on the spot, "Is there such a cheat? Those damn cuckold men, do you want a little face?"
