With the body of a king, he will naturally have more younger brothers soon, and in view of the accident last time, Seniore does not want to communicate more with other younger brothers, lest he will only increase his sadness after they hang up.

Senior, riding Feifei, made some observations around the territory, and found that the number of undead in the Bone Land began to increase, and a huge ghoul in the west, with more than fifty minions, was expanding into his territory, this disgusting, crumpled fat belly, relying on his huge power, did not pay attention to any undead creatures.

"When it's his turn to be king, it's unreasonable. Seniore grumbled indignantly in heaven.

"Lord Prince, this is the underworld, and it is normal to have no heavenly reason. Feifei comforted.

"Go back, it looks like we need to set up our defenses and defend our own tomb!"

Seniore returned to the tomb and began to review his troops, in addition to the old subordinates Da Hei and Xiao Qi, there were also three new first-level skeletons, a first-level zombie, a second-level vampire, and a small hellhound, but the only one-headed Cerberus was simply scum. Compared to the ghoul, it's obviously not an opponent, that idiot actually has a little devil, a little devil who can pollute magic, it's really a headache, no, it should be a headache for pigs.

"Could it be that we have to back down, give up this beautiful tombstone land to the ghouls, and then find another way out in the Black Forest?" Senior was a little unwilling, but he would definitely not be able to resist it.

"him!" roared loudly.

"(him) mother, every time you know (him) mother, but the ghoul he doesn't have a mother at all, my black brother. Seniore clutched his head, caught in a predicament.

It so happened that the ghosts in the tomb began to sing again.

"The fire of heaven burns and burns, and it can't burn my body;

The wind blew and blew, and it couldn't charm my eyes;

Poisonous juice sprays and sprays, and it can't melt my soul. ”

"Nima, where did you learn these songs, sister ghost, don't torture me, find your companions, go to the ghouls and sing them, give them a chorus, and make them all crazy, okay?"

The ghost actually understood Senior's order this time, and his body shook a few times, and then flew out of the tomb.

"We have a vote by show of hands, and those who don't have hands can use claws instead, and those who think they should give up the tomb, please raise their hands. The Hedgehog Prince said.

Only two first-level skeletons raised their hands, and the other undead all objected, the skeletons were all subordinates of Da Hei, this guy couldn't hold back at that time, and angrily gave the skeletons a slap in the face: "Waste, waste! You might as well dig a pit and bury yourself." ”

"Pit digging, by the way, remember our tactics against the big mummies, it was the pit that won the pit victory. "But this time, instead of simply digging a pit, we're going to dig a tunnel to build a bunker, build an underworld dungeon, and use the hole to defeat our enemies." ”

The younger brothers shook their heads, indicating that they didn't understand.

Seniore had no choice but to stretch out a bone finger and draw a picture in the ground to explain, it first drew a straight line and said, "This, it means the ground, understand?"

The undead all nodded, only one skeleton shook its head again, and Da Hei was so angry that he was about to explode, and slapped it again: "I don't understand the ground, waste, you are not as good as Cerberus." ”

Cerberus expressed his displeasure and protested with his soul: "Great prince of hedgehogs, humans are discriminating against animals. ”

"Enough, don't make any noise, what kind of human animals, we are all undead, just a few broken bones. Seniore said angrily, "Listen to me obediently, your little brother is not very good, and you need to strengthen your training." ”

Da Hei hurriedly bowed down and said, "Yes, the great prince of hedgehogs, they haven't opened their minds yet, I'll open a small stove for them when I go back." ”

Seniors pointed to the line and said: "This is the ground, no matter how strong the ghoul team is, it will only move on the top of this line, I can't imagine that we are below, as long as we dig out the tunnels and make some fortresses to the ground, we can surprise them and destroy them one by one." ”

"But master, we are below, and we can't see above either. Xiao Qifa asked.

"Look, you have to learn from Xiao Qi, it already thinks backwards. "But don't forget, we still have Feifei, it's in the sky, it can observe the enemy, and at the same time make soul contact with me, as long as it tells me the enemy's location, we can accurately counterattack." Feifei, do you understand?"

"I don't understand, how can I tell you the location of the enemy?" Feifei asked.

"When I dig out the bunker and number it, you just have to say how close the enemy is to the number of places, and we will understand. Hedgehog explained.

"Number, what's that?" Almost at the same time, all the undead were blinded.

"From now on," said Senior, "I'll give you math lessons while digging holes as I ask." ”

Fortunately, the ghouls, although powerful, are still some distance from Senior's territory, and they are blindly and aimlessly, not noticing the great prince of hedgehogs. Coupled with the recent distraction from a chorus of ghosts, it gave Seniore time to dig tunnels and teach math.

The first math lesson in the underworld was not easy, and even if the minions understood what one was, it would take a lot of effort on the part of the Hedgehog Prince, but of course, it didn't have heart and blood.

After learning the first lesson, Da Hei reported to his master his experience: "Great Hedgehog Prince, the one you said is really amazing, the stone can be one, the finger can also be one, the bone can also be one, and the shield, how can everything be one?"

Seniors really wanted to tear down the big black: "Everything is one!"

Da Hei realized something, and even said a classic conclusion: "It turns out that the whole world is made up of one, and there is one, one, and one everywhere." ”

It wasn't until hundreds of meters of tunnels had been dug that the undead had learned ten, and they could now queue up to count and know what number they were. Seniors felt that it was not easy for him, and he had created a precedent in the underworld, and in the future, hundreds of millions of undead should give him a statue of this enlightenment teacher. Seniors drew a simple diagram on the wall, marked the number of each bunker exit, and had each servant memorize it, before starting to practice tactics.

"Alright, now let's go to bunker three, and think, where is three?" commanded Senior.

As a result, only Xiao Qi went to the right position, and the other undead ran around for a while, and Seniore stood beside Xiao Qi angrily and said, "This is No. 3, damn, you pigs!"
