As soon as he thought of the passage outside the city that connected to the underground world, Baron Qin Man was a little restless, and after a polite word with Lin Mo and the twin sisters, he hurriedly left the inn with his entourage.

"It's a pity that he's just a baron, and if he's a duke or prince, then the passage to the realm of the underworld isn't just a disaster, it's a good thing. ”

Lin Mo looked at the back of Baron Qin Man's departure and shook his head regretfully.

Compared to the surface world, the mysterious underground world is full of countless unknown dangers, but it contains countless precious resources.

Rare ores, gems, monsters and monsters and other animals and plants, whether in variety, quality or quantity, make the intelligent species on the ground crazy.

The passage connecting the earthly and subterranean realms could easily become an inexhaustible source of wealth, but all this is based on having enough force and power, without which it will only bring unbearable disasters to oneself.

"In this way, the favor Baron Qin Man owes you is probably getting heavier and heavier. ”

Li Muxin smiled knowingly on his face under the silver mask.

But seeing the dragon knight shook his head, he said: "In fact, the personal debt between me and Baron Qin Man only exists in the name of words, and it may not have the opportunity to use it in the future. ”

And since it is called a favor, it is naturally impossible to convert it into gold coins.

The clever Baron Qin Man did a perfect job in both face and lining, except for paying a gold coin that could be earned back quickly, he didn't actually pay anything more.

Li Mubing quickly figured out this joint, and said stupidly: "The aristocratic laws of this world are really profound!"

"Don't worry, it took at least a year or two for me and the gold coin to fully adapt to the life of the earth, and after a long time, you will naturally understand. Also able to adapt. ”

Lin Mo said as he lifted the chest full of gold coins and returned to his guest room with the twin sisters.

opened the door with the key, but saw the two sisters' student Dundot lying on the square table in the main hall of the guest room dozing, and when he heard someone open the door, he quickly opened his eyes.

Behind Lord Morin, the pair of sisters wearing silver masks like mirrors were naturally the teachers he respected.

"Lord Morin, teacher!"

The young man in the wine inn stood up and hurriedly came to pick up the box in Lin Mo's hand.

"No help. Well, how did things go today?"

Lin Mo's gaze fell on Dundalt's back, there were several more pockets and barrels in the main hall, and it seemed that today's purchase was going well.

After placing the wooden box full of gold coins on the tabletop, he took out the silver dragon egg, released his spiritual power to probe into the space inside the egg, and then lightly touched the box, the wooden box disappeared on the table in an instant, and the next second it was quietly suspended in the mysterious space of the silver dragon egg.

"It's ok. It's just that a few shops in the city don't have much inventory, and according to the proportion, I only bought more than 600 catties after running all over the city. ”

Dundot rubbed his eyes and replied.

"Six hundred pounds. Enough. ”

Li Mubing and her sister Li Muxin glanced at each other, and nodded in unison, the black powder made from these raw materials is not a problem to put over the two black fangs, even if it is to level 20 heads.

The two sisters did not hide the formula ratio of gunpowder from the student. If you want to make qualified black powder, it is far from enough to know the coordination and proportions of the road.

If there is really any second goods who think that black powder can be prepared with one nitrate, two sulfur and three charcoal, then. The two sisters can only tease this hehehe.

The least likely thing to appear in the textbooks of civilians is the truth.

"Dundot, you've worked hard today, go to sleep first. Li Mubing patted Dundot, who was haunted by sleepy insects again, and then said to his sister: "Sister, we have to work overtime at night." ”

Sleepy, Dundot yawned for days and turned around and left the room as if it were an amnesty, looking for his dreamland.

"Lieutenant Colonel Lin Mo, well, you have to count overtime pay!"

Li Muxin made a rare joke with the dragon knight.

"Well, the state is statutory, triple the salary!"

The dragon knight also climbed the pole, and the three of them laughed in unison.

With Lin Mo's help, the two sisters immediately got busy.

It is almost an impossible task to dispose of all these more than 600 catties of materials in one night, Li Muxin and Li Mubing only plan to prepare more than 100 catties of black powder to deal with the remaining two demonic beasts, plus the battle qi, it is almost enough.

The result of the two girls accompanying the dragon knight all night was that after the sun rose, only Lin Mo and a few light cavalry were left in the team leaving the city.

Staying up too late is not conducive to concentration, and it is also the enemy of women's beauty.

The satellite outside the firmament was still very dutifully locked onto these two targets, and Lin Mo and the light cavalry didn't have much effort to find their hiding place.

Compared to the first day, which easily killed a Kurosawa fang, the second day was not so smooth.

The two demonic beasts were hiding in one place, one was resting, the other was on guard, Lin Mo had just thrown out the first bomb, and before it could be detonated, it alarmed them.

After seeing clearly the two black demonic beasts that suddenly burst out and pounced on him at a lightning speed, the dragon knight did not expect that these two demonic beasts were not only Kurosawa fangs, but two blue-blooded beasts, one male and one female.

It was a crustal monster predator that was even more ferocious than Kurosawa's fang, and it seemed to be just a couple.

The Kurosawa fang that he killed yesterday may have been the prey of the pair of blue-blooded spirits, and the three-headed demonic beast strayed into a passage to the surface during the pursuit and escape.

Among the various species under the firmament, only the actual combat power of ordinary beasts can be equal to that of the human race, the actual combat power of the same level of demonic beasts is one order higher than that of the human race, the demon beasts are two orders higher, and the most powerful dragon clan can be three orders higher.

The two blue-blooded Immortal Biao are both powerful demonic beasts of the ninth order, which means that the demonic beasts of the ninth order are actually equivalent to the level of powerhouses of the first order.

Among the few advantages that Lin Mo could rely on, in addition to the fact that it was daytime, the crustal creatures hated the harsh sunlight as well as the nocturnal creatures, and the spirit of the blue-blooded spirit was a little sluggish, and the two turtle demonic beasts were also unfamiliar with the power of the black powder bomb and the low-altitude flight ability of the "Dragon General" tactical armor.

Good things like throwing a bomb directly into the opponent's mouth will not happen again and again, and the dragon knight chooses to bomb at a low altitude.

Due to the narrow space of the Underground Epoch, there are very few higher spaces, and there are many terrestrial and aquatic species in the earth's crust, while the flying species are very rare, and even if there are, they are not large, so Lin Mo can activate the anti-gravity field of the SEG core unit of the "Dragon General", suspend it in mid-air with peace of mind, and throw bombs on the heads of the two blue-blooded Immortal Biao who have fallen into a thunderstorm.

Calculating the detonation time of the fuse, several bombs with small charges blew the pair to the ground, and they roared angrily in the sky.

What else can you do but roar?

Jumping tens of meters high?

After all, they are not fleas, in fact, with their body shape, it is already very remarkable to be able to jump more than ten meters, but they are not able to reach Lin Mo, who is suspended at a height of 100 meters above the ground.

As a Warcraft, it is natural to have innate spells, but the several spell attacks possessed by the Blue Blood Immortal Biao are not worth mentioning in front of the professional Sky Knight.

First of all, you have to win the ballistic deduction model of the "Dragon General", and secondly, you have to win the prediction ability of the Dragon Knight, no matter which one, it is not easy to get Lin Mo wearing the "Dragon General" tactical armor with such weak anti-aircraft firepower.

The contest between the two is no different from two M1A2 Abrams main battle tanks against a Wuzhi-10, although from the comparison of offensive and defensive capabilities, both sides are very painful, but the former is completely in the dilemma of being beaten passively.

After repeatedly jumping up and pounce to no avail, the two blue-blooded Mingbiao who were blown up and injured all over their bodies let out a low roar of rage, turned around and fled, but Lin Mo was willing to let them go, increasing the output power of the plasma engine, and followed closely.

It's just that the speed of the two ninth-order demonic beasts is still too fast, and after a while, the huge figure of the blue-blooded dark biao disappeared into Lin Mo's vision.

Fortunately, the satellite "White Dew" outside the sky is still locked on them, and it is impossible to evade the tracking of the satellite with speed.

"Lieutenant Colonel Lin Mo, is it going well?"

gave up continuing the pursuit, and Lin Mo, who had just fallen back to the ground, received a call from Li Muxin, the sister of the twin stars.

After receiving satellite relay support, the communication distance between the two sisters' individual special communicators and Lin Mo immediately increased countless times, and they were no longer limited by the basic communication power of the equipment.

As long as the satellite signal is covered, the dual convenience can achieve barrier-free instant calls.

"It's not very smooth, it's two ninth-order demonic beasts, more cunning and fierce than Kurosawa's fang, I only injured them, but let them run away, but the satellite is tracking, I will catch them up soon." ”

Lin Mo was very helpless, it was not so easy for the other party to stop him if he wanted to escape.

There is only one result of fighting the ground, feeding the monster by yourself, and there is no luck.

I thought it would be a quick and quick extermination, but I didn't expect it to become a protracted war, thank God that yesterday Dundot bought a large amount of black powder materials, and the Gemini sisters stayed up late to make a lot of bombs, at least there was enough ammunition to deal with it.

"Be careful! Just received the latest news, Baron Qin Man's people found the entrance to the underground realm. ”

"Where?"

"Well, it's about 20 miles east of Yangshui City. ”

"I'll look at the map, uh, hell! those two blue-headed Dark Men might want to escape back to the Underworld. (To be continued......)
