There is a no-fly realm above the majestic Great Wall of Ray Eddy, and all flying monsters cannot directly pass through this area, so they can only climb the city wall like countless ground monsters and fight with the defenders on the wall. Relying on this legendary Great Wall, even when monsters were ravaging, the four southern provinces of the Norsbod Kingdom were still rarely harassed by monsters.

Under the demonic moon, some monsters rushed out of the northern forest and bustled against the city walls.

On the Great Wall, an old knight with gray hair in bright armor stood on the city wall, looking into the distance.

"My lord, go down and rest, and leave it to us here." A young knight said to the old knight.

"Berry, did you find out? The number of attacking monsters has decreased again. The old knight stared at the monsters beneath the walls.

"That's a good thing." The young knight looked at the city walls with a relaxed face.

Goblins, kobolds, and giant wolves, with these monsters, it's enough to climb the city walls! So even though it was a demonic night, most of the defenders were relaxed and didn't even bother to use their bows and arrows - those guys couldn't threaten the walls anyway.

"Berry, we all know that the demons who are now occupying the north are a group of intelligent creatures." The old knight's face was full of sorrow, "Do you think they would be so kind as to deliberately reduce the pressure on the Great Wall?" ”

"Hmm...... Didn't the mission say that? In those nests controlled by demons, the number of monsters will drop sharply, so isn't it normal for fewer and fewer monsters to besiege the city? ”

"The number decreases, but it doesn't disappear! The Imperial Council connived at the Demon Clan to occupy the north, which was definitely a wrong decision! The old knight frowned, "I have a hunch that when the demons launch a general attack, it will be when the Great Wall falls. ”

The young knight kept his mouth shut. This kind of questioning of the leader is not something that a young person like himself can interject.

The night was peaceful, and the magical night passed quickly, but for the defenders, the work was not over.

Due to the magical night, the vegetation around the Great Wall suddenly grew wildly. It's just inside the Great Wall, but if the vegetation outside is not cleared, it will not only obstruct the view, but also turn into monsters, and maybe even climb the city wall directly! The defenders obviously won't allow this to happen, so it's worth clearing the surrounding vegetation after the night of the magic.

Clearing the vegetation is not difficult, all it takes is a fire to turn all the plants outside to ashes. But after half a year of this, the guards discovered a frightening situation: the plants outside the city actually showed fire resistance!

The flames could not ignite the plants, even if they were doused with oil, so the guards had to resort to a clumsy solution - take their scythes and go out to weed them manually.

This is a very dangerous act. Unlike staying on a safe wall, it's not safe to clear vegetation, because you don't know if those seemingly ordinary plants will suddenly turn into monsters and attack you, or if you will suddenly be attacked by demons.

After a few surprise attacks, the garrisons began to tend to leave the "chores" of clearing vegetation to the adventurous guilds.

For the garrison, this is a very good business. Soldiers need to pay a pension when they die, but the adventurers who die don't need the gold of the lord's lords, and if these outcasts die, the security in the city can be slightly improved.

Therefore, when the Adventure Guild was established, the commander of the Raidy Fortress left this "seemingly safe" job to the Adventure Guild and handed over the matter to the "outcasts" to deal with. However, this seemingly trouble-free behavior also gave Green the opportunity to enter and exit the Great Wall fortress freely.

The north gate of the Ryeddy Fortress.

Wearing the uniform of the Royal Academy and carrying a backpack, Green was negotiating with the guards at the city gate.

"I'm a magician, and I want to go out and collect some samples of dirt and plants for research." Carrying a backpack, Green explained to the guards, "I'm interested in the fire resistance that appears on plants outside the city. Humans also gain resistance through burning, electric shock, etc., when cultivating, but this phenomenon is rarely seen in plants......"

After Green's explanation, the suspicious look on the guard's face slowly disappeared: "Do you have a way to deal with the fire resistance that appears on those plants?" ”

"Oh~ Although this is not my research topic, I do not rule out the possibility of discovering 'herbicides' during the research process."

Green's words intrigued the guards: "Herbicides? ”

"Simply put, a poison for a specific plant! Of course, this is just speculation. ”

"It's dangerous out there. Last night was a demonic night, and maybe there were any monsters left outside. Green's words made the guards full of favor for Green, so they couldn't help but kindly advise, "If you want to go out of the city to collect samples, it is best to go to the adventure guild to commission and let those adventurers help you collect them." A person of noble status like you doesn't need to take risks. ”

"Ah, don't worry." Green smiled and patted the weapon on his waist, "I'm not unprepared. ”

Looking at Green's indifferent expression, the guard frowned slightly. The guards were a little embarrassed by Green's attitude.

"Wait a minute, I'll ask the captain." In the end, the guards decided to report the situation to their superiors.

"Okay." Green didn't embarrass the other either.

Green is not playing smuggling or smuggling now, but going out to collect supplies in the name of "academic research" - by the way, he recovers his "Demon King's Heart", so Green naturally does not have to worry about the other party's cross-examination.

It didn't take long for the guards to come with a young officer in knight's armor.

After some inquiry, the young officer learned that Grimm had left the city to collect dirt and herbs to conduct research on flame resistance, and the middle-aged officer couldn't help but be in awe of Grimm.

"In that case, let's send someone out with you." The young officer spoke, "It's not safe outside the city, not only are there threats from monsters, but the adventurers aren't good people who obey the law. ”

Hearing the young officer's words, Green looked confused. it! Did I accidentally overbrush my favor?

Clearly, Green underestimated the extent to which the officers were concerned about the "weeds." As soon as he heard that Green was planning to study those weeds and find herbicides, he decided to send someone to guarantee Green's mission.

Soon, a squad of twelve people was assembled, and the leader of the team was the knightly officer named "Berry".

In the face of the "enthusiastic help" of the knightly officer, Green felt a little broken in his heart! This is a little different from my imagination! For Green, going out of the city to gather resources is just an excuse, and the real purpose is to reclaim his heart and bring back some magic crystals as working capital. But with so many people now, what's going on with that?
