Chapter 6

 Ges and Daniel and others have left.

 Du Mingna sat alone in his own bedroom.

 The bed board was already laid out, with some hay on top.

 A layer of mattress was also placed on the hay.

 Comfortable, it was actually quite comfortable.

 The warmth of the hay was quite good.

 But compared to Du Mingna's past life, there was a big gap.

 Du Mingna was not in the mood to think about enjoying things now.

 Life, well, as long as he could get by, he could endure it for now.

 Compared to these external things, staying alive was more important.

 Not being afraid of death is not contradictory to striving to survive.

 He wanted to survive in this strange world.

 The attacking monsters were the big trouble he had to deal with.

 He couldn't let the number of attacking monsters double because he didn't complete the task, oh, now it's doubled.

 But where could he get students from? Have Old John cooperate with him? What could he teach Old John? Du Mingna thought about it and couldn't come up with anything.

 The system wouldn't let him take advantage like that.

 He had to teach Old John something substantial for at least half a year before the system would recognize Old John as a student.

 Old John could read and write.

 Old John also had more life skills than Du Mingna.

 Du Mingna wondered if he could teach Old John things from his previous life in this world.

 But many things from that world were meaningless to the residents of this world.

 What use would his world's language have for the people of this world? The system also didn't approve of such courses.

 Du Mingna also considered teaching math.

 But if Old John could do basic multiplication, division, addition, and subtraction, Du Mingna would have to bring out functions if he wanted to teach more.

 How many people could remember functions they learned before after graduating? Teaching for a day or two might help scrape through by relying on memory.

 But to ensure teaching for half a year or more, Du Mingna couldn't do it.

 Teaching the villagers of Hui Sheng Village to read and write with the knowledge he had acquired in this world was actually a good idea.

 But the relationship between the villagers and him was too bad, and Du Mingna didn't know if he could persuade the villagers to follow him in learning.

 If it didn't work, he might have to let Old John be the persuader and try to coax one or two villagers to come and learn from him.

 Du Mingna sighed inwardly.

 He temporarily put this matter aside and earnestly checked his system messages.

 He called out the system panel in his mind, first clicked into the backpack, and checked the perfect-grade mysterious gift box he had received.

 It was a red square box wrapped in a golden ribbon.

 It was in the first slot of the backpack, emitting a soft light.

 With a thought, the box jumped out of the backpack slot, enlarged, and emitted an even more dazzling but still soft light.

 Finally, the light dissipated.

 Du Mingna received an additional piece of information.

 He could freely toggle the special effects of the gift box.

 Without the special effects, he could instantly open the gift box and retrieve its contents in time.

 At a critical moment, this might save his life.

 The perfect mysterious gift box contributed three things to Du Mingna.

 One was a map book, "Grey Rock Kingdom Map.

" The Grey Rock Kingdom, the name of the country where Du Mingna was located, belonged to the Qingsen Continent.

 The second was a ruler, with a note saying it could ensure that it would hurt but not harm people when used.

 The ruler was tough enough and wouldn't be easily destroyed.

 The third was a bottle of potion, a basic constitution potion that could enhance a person's basic constitution.

 Without hesitation, Du Mingna took out the potion and drank it all in one gulp.

 This was a good thing that could enhance his combat power! Even if the increase was not significant, it was better than nothing.

 The potion was a bit sweet, and the taste was quite good.

 After drinking it, there was no residue left in the potion bottle.

 Du Mingna smacked his lips.

 He felt a warm current rising from his lower abdomen, quickly flowing through his body, quite comfortable.

 He seemed to hear the sound of bones creaking inside his body.

 He tried moving his fingers and felt a slight increase in grip strength, but not much sensation.

 The system was designed to help him establish a prestigious school rather than enhance his personal strength.

 He might be able to obtain something from the system to improve his strength, but he couldn't accurately determine how much his strength had increased.

 His personal strength was not yet quantified.

 Perhaps after completing more main tasks, he could have a personal strength panel, but not now.

 Du Mingna took out the ruler again.

 The ruler was entirely black.

 It was a wooden board about half a meter long, three centimeters wide, and one centimeter thick, emitting a natural shine, very beautiful.

 Du Mingna raised his right hand holding the ruler slightly.

 He instinctively slapped his left palm.

 When you get something fun, you try it on yourself first, which is quite normal.

 After all, slapping oneself ensures control over the force, only causing a slight sensation without feeling pain.

 The ruler was raised, but Du Mingna's movement froze.

 Before taking out the ruler, he had read the instructions! This ruler doesn't hurt people when it hits, but it does hurt.

 Did he really want to try it on himself? Du Mingna gritted his teeth and made up his mind.

 Snap.

 The sound was light but crisp.

 He grimaced in pain, his features almost contorted.

 Ouch! The instructions were not deceiving! It really hurts when the ruler hits, making people want to cry out in pain! Du Mingna felt like he was crazy to try it on himself! "Ding! The host's endurance still needs to be strengthened.

 "This system firmly believes that pain helps people remember what they should and shouldn't do.

 But if terrible harm is inflicted in order to make people feel pain, that is not the right way for a teacher to treat students.

 "Therefore, this system has specially launched five types of rulers: the ruler, the ruler that hurts when hitting, the ruler that hurts a lot when hitting, the ruler that hurts a lot when hitting, and the ruler that hurts a lot when hitting.

 "The host has only drawn the lowest-level ruler for now!" Du Mingna's mouth twitched.

 According to the system's words, the other four rulers that follow might indeed not cause physical harm, but they would definitely cause mental harm! He carefully examined the ruler in his hand.

 After personally experiencing the power of the ruler hitting, Du Mingna made a decision.

 As long as his students didn't commit major mistakes, he would never use the ruler to punish them.

 It hurts, doesn't cause physical harm, but it's not good for their mental well-being.

 If a student is really unruly, strict discipline is necessary.

 In the future, if he draws other products from the ruler system, he won't use them on his students either.

 But that doesn't mean the ruler is useless.

 Du Mingna had already thought about using the ruler in combat and what effect it could have.

 The sudden intense pain would catch the enemy off guard, possibly rendering them temporarily unable to fight.

 In a life-or-death battle, even the slightest unexpected event could affect the outcome, let alone unbearable pain for the enemy? Indeed, when facing off against monsters, they might become more ferocious amidst the pain, suddenly unleashing greater power.

 However, this burst of power couldn't be sustained for long, and after the outburst, the monster would be rendered powerless by the pain.

 Du Mingna had personally experienced the power of the ruler and knew how his body suddenly became weak when the pain struck.

 This should be another function that the system didn't list but the ruler actually possessed.

 It could reduce the retaliatory ability of the person being hit.

 Among the ruler system products, the higher-level rulers should have even stronger additional effects.

 Therefore, this ruler should be used against enemies! The ruler may not be lethal, but its toughness and pain-inducing properties are enough to make it a competent secondary weapon.

 Du Mingna put away the ruler.

 He casually placed the ruler on the bed and then took out the book "Gray Rock Kingdom Map".

 This is a large A4 book that is over twenty centimeters thick.

 When the map fell into Du Mingna's hands, it was so heavy that Du Mingna almost couldn't hold it steady.

 The cover of the map depicts the national map of the Gray Rock Kingdom, as well as some surrounding areas.

 Places like the Gray Rope Village where Du Mingna is located belong to the border of the Gray Rock Kingdom, adjacent to the Tupo Mountains, which are already part of the Gray Rock Kingdom's border.

 The national map on the cover also outlines various noble territories of different sizes.

 Du Mingna easily found the territory of Viscount Hall.

 Although Viscount Hall gave him the Gray Rope Village, he does not hold a title, and currently the Gray Rope Village still falls within Viscount Hall's territory, although Viscount Hall's people cannot interfere with the village without Du Mingna's permission.

 Only when Du Mingna acquires a title and is eligible to independently own land can the Gray Rope Village truly break away from Viscount Hall.

 If something were to happen to Viscount Hall before Du Mingna acquires a title and his land is confiscated, then the Gray Rope Village would no longer belong to Du Mingna.

 The first page inside the map depicts the Gray Rope Village.

 Du Mingna's pupils contracted as he looked at it.

 The map was too vivid, but unfortunately, it was shrouded in a layer of mist.

 His house and the path he took when entering the Gray Rope Village were clear, but areas further away were obscured by the mist.

 The mist was not thick enough to completely obscure the content of the map, but it made it uncomfortable for him to look at.

 After looking at the mist-covered areas a few more times, he felt dizzy and nauseous.

 "Friendly reminder: The maps produced by the system have real-time updating capabilities.

 "The original maps are shrouded in mist, and the host needs to use mental energy to view the map through the mist.

 If the host continues to view the map forcefully when their mental energy is insufficient, it will consume the host's vitality.

 "The mist on the map will dissipate in areas where the host has traveled.

 Afterward, even if the map is updated, it will not be shrouded in mist again.

 "This map comes with a regular map booklet.

" Du Mingna immediately turned the entire book over and opened the back cover.

 Sure enough, the regular map booklet was located between the back cover and the last page.

 Du Mingna took out this map booklet.

 Great, this time he was looking at a conventional map.

 North is up, south is down, east is left, and west is right, with different symbols marking mountains, rivers, cities, and villages.

 The booklet is not thick and has limited accuracy.

 The smallest unit is noble territory, without further subdivisions.

 Areas directly under the jurisdiction of the kingdom are divided into five large sections, each distributed across five pages.
