Green spent a day in the caveman's mushroom grove, where he trained the two new troglodytes under his hand, learned about the cavemen, and captured several other troglodytes to conduct "control experiments" with them.

Under Green's teaching, the two demon cavemen quickly mastered the words that had never existed in the caveman tribe, such as carrying luggage, backpacks, mining pickaxes, magic, and magic power, but the rest of the ordinary cavemen did not show the powerful learning ability of the demon cavemen, even after being taught by Green many times, those ordinary cavemen only understood the meaning of the word "punishment" - in the minds of the cavemen, "punishment" is something more terrible than "karma".

During the "controlled experiment", the performance of ordinary cavemen was terrible, but the performance of the two demon cavemen barely met the standard that Green expected.

Influenced by the bloodline of the demons, the two demon cavemen not only mastered many words and ways to communicate with Green in a very short period of time, but also mastered the racial talent of the demon race of "Magic Explosion" in a very short period of time.

————

Burst of mana: A large amount of mana in the body is consumed, and one's physical fitness is greatly strengthened in an instant, but it is possible to fall into weakness for a period of time after strengthening.

————

For the demons with strong magic in their blood, it is an instinct to use magic to strengthen their flesh, and all creatures will naturally be able to obtain the physical enhancement brought by magic after becoming a demon. "Mana Enhancement" is a passive ability that allows weak girls to exert strength that is not inferior to that of adult men. In addition to passive "magic power enhancement", some demons can take the initiative to consume a large amount of magic power in their bodies, so as to exert a power beyond the limit in a short period of time - that is, "magic explosion".

Burst of magic is the dividing line between the transcendent and the black iron. After mastering the "Burst of Magic", these cavemen also have the ability to fight against the dwarven warriors, which also means that these cavemen have the value of becoming "soldiers".

After feasting the two demon cavemen and the two ordinary cavemen, Green pointed to the wall next to him and ordered the cavemen, "You guys, dig holes with all your might." Half an hour time limit. Those who dig slowly, are punished! ”

"Quack!" When the four cavemen heard Green's words, they rushed to the wall without hesitation, picked up a stone from the ground, and began digging.

The caveman struck the wall with a stone, loosening the rocks on the wall, and then began to gouge with his rough hands. Cavemen have thin arms, but large palms and hard nails, allowing them to dig through dirt with ease, as well as loose rock like chicken claws—just smash it with something before planing. The cavemen were not very good at fighting, but they were not slow to burrow, and soon dug a tunnel large enough for their bodies to burrow.

I saw the cavemen crawling in like insects with their hands and feet, two slender arms digging inside, feet kicking behind, and fine sand and gravel continued to flow out of the cave along the gaps on both sides of the body.

Green stood outside, estimating the speed of the cavemen's digging.

There is no doubt that the two demon cavemen are digging much faster than the two ordinary cavemen, and when the two demon cavemen have already stuffed their whole body into the tunnel, the two ordinary cavemen have just dug a small pit that can barely fit their heads in. But after ten minutes, the digging speed of the two demon cavemen began to slow down - the magic power in their bodies had been almost consumed, but the digging speed of the two ordinary cavemen had not changed much.

"The explosiveness of the demons is strong, and the endurance of ordinary cavemen is relatively strong." Green assessed the time and speed, and used identification techniques to observe the physical condition of the cavemen, "In other words, it is better to leave the excavation of the tunnel to ordinary cavemen." ”

Half an hour passed quickly.

I have to admit that although cavemen look ugly, their ability to dig holes is really good. In an hour, several cavemen dug a hole large enough to plug themselves, and the hole dug by the demon caveman was about a meter longer than that of ordinary cavemen. This isn't as efficient as a dwarf who is good at using tools, but the fact that he can achieve this kind of efficiency with his fingers without any tools is enough to prove that cavemen are strong at digging.

"There should be more than fifty adult cavemen in the forest, and it won't be difficult to convert them into demons. However, after becoming a demon, food will be a big problem, and ordinary underground mushrooms cannot fully meet the demons' need for magic intake. Green looked at the map and estimated the distance from the Demon Clan.

Judging from the map, this place is only a few dozen kilometers away from the Demon Clan, which is a day away, and Storm Eagle can be reached in one or two hours. But this is a mountainous area, and it is still underground, and the distance of these tens of kilometers is a bit scary. If the cavemen were to dig a tunnel to the demons, it would take years to dig it, and that's not even taking into account the possibility of collapse during the excavation.

It is obviously impossible to dig a tunnel that leads directly to the demon realm, but if it is only from the underground to the surface...... It will be completed in about one or two months. As long as there is a short route to the surface, it is possible to deliver supplies from the surface on a regular basis. As long as logistical supplies can be secured, then the army can be massively expanded, establishing a stronghold here and collecting nearby crystal ore veins.

Green set his eyes on the halfling standing not far away.

Feeling Green's gaze, the halfling man looked frozen, and hurriedly ran over and flattered: "Boss, is there something wrong?" ”

"Are you interested in being a lord?" Green asked suddenly.

"Lord?" There was a hint of surprise on the halfling's face, "Oh! Absolutely. Boss, do you want to make me a lord? ”

"I need a lord who is smart enough to manage this place." Green pointed to the mushroom forest next to it.

The halfling looked at the mushroom grove where the cavemen lived, then at Grimm, then at the mushroom grove, then at Grimm, and after looking back and forth a few times, the halfling finally determined that Grimm seemed to be telling the truth.

"Boss, are you kidding?"

"I'm not kidding." Green looked serious.

"Oh~ Boss, I think you seem to have some misunderstanding of the word 'lord'. A lord is the de jure supreme ruler of a territory, and a bandit leader who is king of a mountain is not the same thing! ”

"As long as you are strong enough to force others to acknowledge your occupation of the locality, then you are a 'liege'. On the other hand, if everyone does not recognize your identity, then you are the leader of the bandits. Green snapped his fingers, "So, as long as you can establish yourself here, then you're a great dungeon lord!" ”

The halfling had a crying and laughing expression on his face: "Boss, you think too highly of me, right?" If I dare to occupy the mountain here, within a few months, the guards of Iron Snow City will come to suppress the bandits! ”

"A few months is enough. As long as you can command these cavemen and dig a tunnel to the surface, then you will be able to get support from the Demon Lord. Green pointed to the caveman next to him, "You also saw the power of those cavemen. After becoming demons, their combat effectiveness is actually not weak, as long as they train well, they may not be able to become a group of qualified warriors. Of course, I didn't expect you to be able to rely on these cavemen to fight against the Dwarven Kingdom army. You can use this as a base to search for other underground creatures in the underworld, and control and win them over by transforming them into demons, so as to increase your power. If the army of the Dwarven Kingdom comes to encircle and suppress you, and you are unable to fight it, you can abandon this stronghold, retreat into the depths of the underground labyrinth, and wait until the army of the Dwarven Kingdom retreats, and then you can come back and reoccupy the place. ”

Green spoke his mind.

In Green's opinion, the underground world is so big, with the short legs of the dwarves, the cavemen only need to hide elsewhere, and the dwarves can only stare dryly. After the dwarven army retreats, with the combat power of the demon cavemen, it is completely possible to recapture this stronghold.

The halfling thought for a moment, then looked at the endless mushroom forest next to him, and a wry smile appeared on his face: "Boss, I don't want to die." ”

"If you don't want to, forget it." Green didn't force it. After all, this kind of thing, my will is very important, and if I don't have enough subjective initiative, forcing him to stay won't help.

"Boss, I didn't want to. I mean, I'm too weak to do the job you've been told. If you can make me stronger, I can try. The halfling paused, "Like, is there a way for you to make me a Golden Tier?" If I can become a master, I think I can try. ”

Green couldn't help but roll his eyes: "Do you think the Golden Rank is Chinese cabbage?" ”

The halfling laughed dryly: "Don't the nobles all have some family cultivation methods that can make it easier for the nobles to advance?" I just wanted to ask if the Demon Clan had a similar cultivation method. ”

"As a new race that has only been born for a few years, the advanced cultivation method of the demon race has not yet been perfected." Green paused, "But there are some advanced methods that are not very perfect, but the sequelae are slightly larger." ”

"Are there any after-effects?"

Green: "All the subjects involved in the experiment have gone crazy because they can't withstand the power of the Golden Order!" Some of the members' bodies collapsed due to the inability to withstand the high amount of mana, and turned into a monster-like existence. ”

The expression on the halfling's face stiffened slightly, and he laughed dryly: "That...... Forget it. I still want to live a few more days. ”

The timid halfling was unwilling to accept this difficult task, and in desperation, Green could only set his eyes on the two demon cavemen.

"You two heard what I just said. I want you to stay and command the cavemen to dig a passage to the surface. Green said to the two demon cavemen.

"Karma! Quack quack! ”

The red-skinned caveman readily accepted Green's orders, but the brown-skinned caveman spoke his mind: "Quack! Rattle! Karma! Quack quack! ”

"Oh? You want to come with me? Green looked at the brown caveman with some surprise, "Why?" ”

Cavemen use clumsy language to convey their slightly more complex thoughts. Under normal circumstances, it is impossible to express such complex thoughts in the language of cavemen, but because of the presence of psychic induction, cavemen still succeed in conveying their thoughts despite their poor verbal expression.

(Eat...... Follow...... Allegiance...... Magic...... Strength...... Advance...... ）

Intermittent thoughts, but they expressed a thought that interested Green: the caveman wanted to follow Grimm all the time, learn magic and power, and go to more places.
