After discussing things with Robert, Suren signed three blank trade licenses, and Robert left in a hurry.

Because the secret space folding circle was repaired, the Zhenbei Fort troops who remained outside the secret territory also withdrew one after another, and the army of Zhenbei City was mobilized again. In the wasteland where Zhenbei City is located, there is no strong force that can fight a large-scale war with Zhenbei City, and now it is more of a small-scale battle.

The monsters in the wilderness are like weeds, as long as you don't pay attention, they can soon grow very luxuriantly, summer is the most abundant season of food in the northern wilderness, those kobolds, goblins, and gnolls began to increase in number, in order to cope with this situation, Suren changed the way the army fights.

The pikemen, archers, centaur cavalry, and the newly added Harpys were broken up and reorganized into small legions, and then led by their respective generals to sweep the area around Zhenbei City, which once again began to clear the territory of monsters and bandits.

Of course, it is unrealistic to completely exterminate these kobolds, goblins, and gnolls, after all, these races are very reproductive, and they are litters all their lives. Suren's intention was to keep their numbers in a low range.

After this kind of extermination operation lasted for a few years, the number of goblins, kobolds, and gnolls gradually decreased, just like the current southern provinces, there are basically no gnolls in the wild, and even the number of goblins and kobolds is very small, which is the result of their long-term efforts for decades.

Other nobles can do it, Suren can do it too, and he also has a strategic map, and those goblin kobold bandits that roam everywhere will be marked on the map as soon as they are discovered, and it is not difficult to eliminate these bandits when the battlefield is unilaterally transparent.

After having the flying class of the Harpy, the field of vision of the Zhenbei City army suddenly doubled several times, and now the tactics have also changed from the beginning of the rain of arrows to cover and the pikemen to advance in formation, becoming the Harpy air attack, the archers cover the shooting, and then the centaur charge, many times when the pikemen rush up, there are basically not many enemies left.

Monsters that are also not injured are used as slaves, and the injured ones are killed directly to gain experience points. When the army in Zhenbei City was clearing up, Su Lunlai also came to the trap camp training ground located outside the city.

After this period of training, this group of sharpshooter guards has all completed their training, and today is the day when they will advance to the camp. The advance of the trapped camp has only a 1 in 5 success rate, and Su Lun gives each of these sharpshooter guards a ball of light, and then lets them advance.

Time passed minute by minute, this time there were as many as sixteen sharpshooter guards participating in the advancement, Su Lun waited quietly outside, and after about fifteen minutes, a ball of light began to return to the tiger talisman trapped in the camp, which indicated that someone had failed to advance.

Su Lun was mentally prepared for this result, and soon within a few minutes, two balls of light returned, and as time went by, more and more balls of light returned to Su Lun's hands.

Soon the time has reached the last ten minutes, and as long as the advance of the trapped camp survives this last period of time, it means that the advance has been successful, but the number of people who are still holding on is only five. At this moment, Su Lun felt that another ball of light had returned to the Tiger Talisman, and there were only four people left who were still advancing.

Time passed minute by minute, Su Lun became more and more nervous, time passed minute by minute, and soon there were only the last five minutes left, a flash of light flashed, another ball of light returned, and finally only these three people remained.

In the last five minutes, Su Lun felt like a year, and finally the system's prompt sound sounded in his ears.

"Congratulations to the host, three of your Sharpshooter Guards have successfully advanced to the Trap Camp. ”

"The current number of trapped factions is 5. ”

Seeing the three trapped camp soldiers who had successfully advanced, Su Lun's mood was finally much better.

......

Just when Zhenbei City was developing rapidly, further north of the Northern Wasteland, the power of the elemental tides was constantly spreading, and a large number of beasts had evolved into demonic beasts, and the races living here also felt threatened.

"Chief Rogers, the expedition to the Great Glacier has returned, and they have brought back the latest news. "In a huge tent, several orcs are discussing something, and outside the tent, tens of thousands of orcs live in this wasteland.

Since the last era, the orcs were expelled by humans, elves and dwarves, and they can only live in the barren northern wasteland, but the orcs still have not given up returning to the fertile south, and within two or three years, the orcs will carry out a large-scale southern invasion.

At this time, the countries bordering the northern wastelands will be the target of orc attacks. There is no strict dividing line between the northern countries and the orcs, but most of them are defended by the help of mountains and rivers, and usually the orc invasion is directly southbound by the northern wasteland.

The location of Zhenbei City is not the main route of the orc army, and when Zhenbei City was first established, Su Lun did not choose the north, but chose the northeast direction, in order not to become the front line of resistance against the orcs.

"Harol, how is the Great Glacier now?" the tall orc chief asked.

"Chief, something is wrong, we have found traces of the White Dragon. The orc named Harol said.

"Great Shaman, it seems that your prophecy is correct. Hearing Harrol's words, the orc chief was silent for a moment and said.

"Now the situation we are facing is obvious, there will be more and more demonic beasts here in the next few days, our living environment will become more and more difficult, if you want to keep the tribe going, there is only one way, and that is to go south!"

"Sons of Geush, it is time of life and death, and I, the chief of the Blackfire Tribe, Rogethus, officially tell you that we need to obtain more fertile land to survive!"

"The weak elves have fallen asleep, the kingdoms of the dwarves have been divided, and we are facing only humans, and if we defeat those humans, we will have a warm and fertile land under the sun!"

"We've been silent for too long, it's time to make those dastardly monkeys pay!"

"Let's fight!"

"Fight! Fight!"

The other orcs roared.

More and more orcs began to roar, and soon tens of thousands of orcs in the entire camp roared angrily, and the sound resounded in the sky.

At the same time, other orc tribes in the northern wasteland also began to act at the same time, and the number of orcs living in the northern wasteland was no less than a million, and according to the characteristics of the orcs all soldiers, they could easily form an army of five or six hundred thousand.

However, orcs usually don't do this, the most fundamental reason is logistics, the orcs don't have enough food, and hundreds of thousands of orc armies will starve to death soon after they gather together, so orcs will generally unite several tribes to form an army of about 50,000 people to attack from multiple areas.

The orc horde is on the move, and a new round of war is about to begin.

......

After dealing with the affairs of Zhenbei City, Su Lun issued an order to purchase the seeds of various demonic plants, and also began the next step of the restoration of the secret realm.

There are also a lot of demonic plants growing in the secret realm, in addition to purple tulips, there are also mutant man-eating flowers, vampire vines, and some amethyst bee colonies.

The ecological area in the secret realm has also begun to be restored, and there are still many wild medicinal herbs in the ecological area, and some of the herbs marked in "Introduction to Potions" can be found here. Most of the demonic plants are easy to deal with, the only trouble is the vampire vine, this dark red thorn vine belongs to a kind of "Activated Vine", it will automatically attack the creatures that come close, and it has toxins of its own, and after killing the prey, it will drag it over and wrap it up and slowly absorb and digest it.

The area of the ecological zone is very large, and although the damage was severe, it is slowly recovering.

Arcanists believe that these four elements are the basic building blocks of the world and the prerequisite for the evolution of all matter.

As wizards who passed on the knowledge of the Arcane Empire, they also inherited this view. It is said that some wizards who have reached the legendary level will leave the main material plane and enter the astral plane to roam other worlds, and this type of wizard is called astral mage.

According to the information left by these astral mages, they have found all kinds of planets, some solid, some liquid, and some gaseous, but the planets that can reproduce intelligent life have a kind of vitality themselves, and almost most of them have the fusion characteristics of these three forms of planets at the same time.

The Grand Arcanists believe that at the beginning of the multiverse, the explosion of essentia energy created the elemental plane of earth, water, wind, and fire, and that the proportions of the elements created a variety of different planetary forms in the process of evolution.

Most of the planets that can carry life are the result of the harmonious integration of the four elements. Only this harmonious plane can give birth to a variety of living beings, and eventually become a prosperous plane.

Similarly, the Arcanists' theory of building super-large half-planes was born from here, and the Grand Arcanists believed that a complete balance of elements could create a new world, a super-large half-plane that would allow life to thrive.

It's not difficult to create the world. Basically, if a legendary wizard is willing to spend his whole life's energy, he can create a relatively small half-dimensional world, but no wizard will do that.

For example, the environment in the secret realm also needs to comply with this requirement, if there is a problem with the ecological construction of the secret realm, and in the end it is just the ecological collapse of the secret realm and reconstruction, then there is a problem with the construction of the basic elements, and the consequence is the collapse of the secret realm, so Su Lun has always been strict when repairing the secret realm.
