Jokes aside, when he came to the town, Liu Li was still frightened by what he saw.

Nearly 1,000 cultivators were digging foundations with shovels or carrying bricks and stones to build the city walls, and there were several cultivators who seemed to be in charge directing the operation on the spot, and from time to time there were high-level cultivators with flying swords in the air patrolling back and forth to prevent wandering demon beasts from invading the construction area, and the scene was noisy.

"What's going on, brother, your sister is very good, right?" Liu Yan walked over with a smug face.

As the saying goes, thirty years in Hedong and thirty years in Hexi, Liu Li finally witnessed it today. In the past, he would never believe that the old lady with a tendon would have such ability, and after thinking about it for more than three years, this old sister of his, was not just going out to wander around.

"Where did you get all these people?" asked Liu Li, pointing to the hard-working practitioners.

Those who practice are generally cultivators in the foundation building period, or bare-chested, or with their sleeves and trouser legs rolled up, working diligently under the scorching sun, even if they are sweating.

"They, sister-in-law Jinxiu recruited them from all over the world with great strength, and she has to pay them 100 spirit coins a day. Thinking of the heavy expenses, Liu Yan sighed.

Liu Li calculated that 1,000 cultivators would cost 100,000 spirit coins a day!

"Sister, tell me honestly, are you a golden beetle son-in-law anywhere?" Liu Li was dumbfounded. It can take as little as a month to build a town, and it adds up to three million dollars!

Liu Yan feigned anger and punched over, and said angrily: "All the spirit coins were scraped together by your sister! What's more, with your brother who doesn't make people worry, my sister still doesn't dare to marry." ”

"Don't worry, in the past three years, I have also relied on my own strength to survive until now!" Liu Li immediately retorted indignantly. When Liu Yan evaporated overnight, leaving him alone to fend for himself in Heyang City, Liu Li has always been haunted.

Liu Yan glanced at it and said, "Then how did I hear that someone seems to have blown up his nest as soon as I came back?"

Liu Li, who was grabbed by the pigtails, blushed, couldn't help muttering in a low voice: "Good things don't go out, bad things spread thousands of miles." Then he changed the topic and said: "Seeing that this town has formed a scale, what are you looking for me to do?"

After speaking, Liu Xingzhong had a bad premonition. Could it be that he was not enough to be dragged to be a coolie?

Liu Yan replied with a wry smile: "Of course, I asked you to help defend this town, now that the monsters are raging outside, and the town has not yet been built, it is particularly vulnerable to attacks by monsters and monsters." Although I have spent a lot of money to hire a hundred cultivators who have reached the fusion stage to help patrol, those monsters and monsters are still invincible. ”

After a pause, Liu Yan suddenly smiled and pinched Liu Li's cheek: "But then again, brother, you are also a magic weapon forger now, right?

Liu Li reflexively covered the storage ring in his hand and said, "I'm very poor!"

Liu Yan said angrily: "My sister is in trouble, and my younger brother is not on anyone!"

Liu Li refused to die: "I don't want spirit coins!, but I have a way to let you save some expenses, sister." ”

"What's the way?" Hearing the cost savings, Liu Yan's beautiful eyes suddenly lit up. For her, this could not be better news.

At present, the completion of the town is less than half, and if it wants to be completely completed, it will take more than a month, and during this period, it will hire more than 100 advanced cultivators to help patrol every day, and the cost will not be enough even if it is a mountain of gold and silver.

Liu Li said with a smug face: "Aren't you afraid that the demon beasts will invade the town?

"It's the strange magic weapon you blew up your home?"

"Can you please stop talking about this!"

Liu Li gritted his teeth angrily and said angrily: "Although it is very troublesome, who called you my sister." When I bury the flame bombs around the town, you can remove the practitioners who have been hired to patrol them. ”

Liu Yan said suspiciously: "Okay?"

"Okay. Liu Li nodded vigorously.

Thinking that his pitiful tens of thousands of spirit coins could be squeezed at any time to fill the bottomless pit in front of him, Liu Li was full of energy!

For the sake of the fanny pack, it must be successful!

Having said that, Liu Li is naturally very aware of the difficulties.

Although the power of the flame bomb is huge, the manufacturing cost is too high, and one will cost 23,000 spirit coins. Moreover, the flame bomb itself has a time limit, in the time of half a pillar of incense, Liu Li removed the spiritual power line in it, and the yin and yang energy inside the flame bomb can explode when it gathers together, but once it exceeds the time of half a pillar of incense, the internal energy cools down, and it will become a dud.

What's more, Liu Li can't always stay around the flame bomb, wait for the monsters and monsters to approach and then ignite the flame bomb, and it is not advisable to wait for the rabbit to wait for the rabbit. In other words, we have to find a way to make the flame bomb buried in the ground explode on its own when it is stepped on by a demon beast.

After sorting out the route, Liu Li, who had a big headache, suddenly felt that it was better to obediently hand over the only remaining spirit coins to Liu Yan.

But if it succeeds, the safety of the town in the future can be greatly guaranteed, after all, it is your own sister, you can't sit idly by, right?

As soon as he thought of this, Liu Li immediately walked out of the town, sat down cross-legged in a remote place, and did not forget to knock Liu Yan's two induction stones and two core stones when he left. Coupled with the materials he bought before he left Heyang City, now Liu Li has three induction stones and three core stones in his hands, and as for the Sanpin Spirit Mine, Liu Li still has a lot, and he can easily gather all the materials to make the Flame Bomb.

Looking at the materials and stones of different colors in front of him, Liu Li was dizzy for a while.

Forging materials for nearly 70,000 spirit coins.

Thinking of the previous days of frugality, just to be able to pay 2,000 spirit taxes a month, Liu Li felt a little emotional.

But the problem that troubled Liu Li was how to make the flame bomb explode on its own the moment it was stepped on by the monsters, and the time limit had to be extended, otherwise everything would be empty talk.

"What should I do?"

Liu Li lay down on the ground bored, looking at the blue sky in a daze.

In the distance, the town was filled with the sound of clanging piles, and the cacophony of roving cultivators besieging demon beasts.

The principle of the Flame Explosion Bomb is to mix and conflict with each other with three induction stones, spirit ores, and core stones that are all yang attributes, and then cause violent explosive energy. And if you use your own spiritual power to form a spiritual power line between these three energies, and prevent these three violent positive energies from coming into contact with each other, you can make the flame bomb explode with your will.

The spirit line may be replaced by other special attribute stones.

However, the time limit for exploding the flame bomb is only half a pillar of incense. In other words, in order to extend this time limit indefinitely, it is necessary to keep the three positive energies inside the flame bomb active all the time, and they will not cool down too quickly.

Liu Li scratched his head with a headache.

He needed a special material that could keep the three energies inside the flame bomb active.

But Liu Li seems to have never seen this special material.

Wait a minute!

Liu Li was a spirit, and he suddenly remembered that when he went hunting the giant demon with Yu Qian yesterday, the red crystal block that he inadvertently obtained!

At that moment, Liu Li hurriedly took out the red crystal block from the storage ring, he remembered that at that time, he only input a little spiritual power, and this red crystal block maintained the light for a long time, and the light could emit scorching heat.

If this red crystal is refined into an extremely thin sheet and embedded in the middle of the flame bomb, it can not only separate the contact of the three solutions, but also when it is subjected to a certain degree of pressure, because of the weak relationship, the flakes will be shattered, and these three energies can be gathered together, isn't this the best material?

What's more, the red crystal itself has a strong persistence, as long as a little spiritual power is injected, it can continue to dissipate heat, and this heat can also make the three separated energies continue to be active for a long time, so that they will not cool down too quickly and become duds!

The more I thought about Liu Li, the more excited I became!

The power of the flame blast is almost comparable to the breath of the 'Wreaver'. The precious materials such as the Sanpin Spirit Mine, the Induction Stone and the Core Stone only created a flame bomb, which was too wasteful

Thrown.

That can subdivide the melted material liquid into more small individuals, although the power will be greatly reduced, but it is enough to kill the demon beast on the spot!

One flame bomb can make fifty giant demons collectively die in Huangquan, so if the flame bomb is split into fifty small flame bombs, its power is enough to kill all the monsters and monsters below the second level in seconds!

Dredging all the blockage problems, Liu Li felt happy.

He's starting to admire his intelligence!――

Within the Dan Sea, pale golden spiritual power surged.

The white Zhitian clan slowly opened his eyes, a pair of unique and bewitching blood pupils, through Liu Li's line of sight, paying attention to Liu Li's every move.

The thin and white lips slowly revealed a wicked smirk.

"Interesting, these third-class creatures, their minds are full of whimsical ideas, it's a pity, it's a pity"

She closed her blood-red eyes again, and concentrated on pranayama-

During the new book period, I am cheeky to ask for collections and recommendations, the more the merrier, and I am grateful!!
