Huh? There's a magic school here.

Throughout Hogwarts that day, students and teachers alike discussed the attack on the Dragon Kingdom outpost. Although the wizarding world possessed soul-attacking magic, they had very little experience with it. This orc attack served as a stark reminder that war between two races could be ruthless and ruthless.

On the edge of the Dawn Forest on the continent of Karen, just as humans were discussing countermeasures, the first batch of 20,000 ogre soldiers finally arrived at the military camp. In order to accommodate these large creatures, the orc slaves had to cut down a large number of trees in the Dawn Forest to build tents.

Samuro inspected the ogre army and had to admit that these ogres were only good for cannon fodder. They were unintelligent and smelled terrible; if it weren't for the ogre mage leading them, Samuro doubted they would have scattered in all directions. However, these large creatures weren't without their merits; their advantage was that they ate almost anything.

Even moldy food, these guys can eat it happily. There's a saying on Earth, something like, "Fools live happily." The orcs' every move is under the surveillance of Earth's human drones. Through analysis of the surveillance video, the staff of the General Staff finally concluded that the orc forces had not yet fully assembled.

Based on this conclusion, the staff officers in the General Staff were divided into two factions. One faction believed that they should take advantage of their defensive position to wait for the enemy to tire themselves out, while the other faction believed that they should take the initiative to attack before the enemy could fully assemble. The defensive faction believed that using their defensive advantage could reduce casualties and deplete the enemy's strength, while the offensive faction believed that launching a preemptive strike before the enemy could establish a firm foothold could eliminate a large number of enemy personnel and reduce the pressure on defense later.

In general, the consensus was that defenses needed to be strengthened and numerous trenches dug, especially since many large structures had been discovered in the orc camp, necessitating the expansion of these trenches. At this moment, the Dragon Kingdom's infrastructure-building prowess was unleashed, with a massive number of excavators and bulldozers springing out from the base to frantically dig around the area. To achieve even better defensive capabilities, the advisors also enlisted the help of wizards to design traps.

These traps were nothing more than landmines and iron spikes. The strategists brought in wizards simply to make these traps more effective. For example, the first batch of traps were concealed by magic, but the second batch was designed to visually swap the traps with normal land.

The traps were arranged in a way that made seemingly normal land appear as if they were traps, with spikes gleaming coldly inside, while seemingly normal land turned out to be real trap pits. The third row of traps then returned to normal, and this repeated, overlapping arrangement thwarted the orcish attack. To completely avoid the traps, the orcs could only stop and probe slowly, but once their attack ceased, they could only endure the relentless harvesting of human firearms.

The strategists, who believed that the best defense is offense, weren't idle either. They were trying various methods to harass the orc camp. Initially, they even deployed the Dragon Kingdom's ballistic missiles, but after several strikes on the orc camp, they realized it was a waste of resources. The expensive ballistic missiles were meant to strike key enemy targets, but what could they possibly find in such a large orc camp? Even if they wiped out thousands of orcs at once, it was still a poor trade-off.

Later, they started thinking about suicide drones, which were cheap, simple, and could be produced in large quantities. A drone costing a few thousand dollars could take down an orc, making the deal worthwhile. So, every day, a large number of suicide drones flew from the outpost to the orc camp.

These harassments greatly annoyed the orcs, who could only send out a large number of professionals to guard the entire camp and intercept the drones. However, the sheer number of drones meant that some always managed to slip through and hit their targets. Later, to reduce the workload of these professionals, the orcs began to station scouts in the Dawn Forest. When not in use, the professionals would rest in the camp, but once a signal was received from the Dawn Forest, they would prepare to engage the enemy.

The extensive use of drones at the outpost, besides causing some harm to the orcs, also ignited the drone market on Earth. After all, the fact that the Dragon Kingdom's military was purchasing large quantities of drones could not be concealed, and many countries on Earth, upon learning of this, began to investigate the Dragon Kingdom. Later, through the tireless efforts of some countries, they finally discovered that these drones had gone to the No. 3 defense node in Zhenjiang City.

The answer to where the drones went was obvious. Soon, all the major countries on Earth knew that China was using drones to fight the orcs. Countless news media outlets and numerous internet celebrities became experts, analyzing what China's move meant. Meanwhile, the other three countries building outposts immediately began purchasing drones.

Besides purchasing commercially available drones, they are also heavily supporting their domestic drone industry. However, they still lag behind China in drone technology, so China profits handsomely from the majority of the market.

As time passed, June arrived on Earth. In Andres's memories of his previous life, orc troops had already crossed spatial rifts and arrived on Earth in June. Although many orcs were suppressed by various countries on Earth, they still suffered considerable losses. However, in this life, Earth not only escaped unscathed, but the war was also pushed to another dimension.

The humans of Earth not only escaped the harm of the alien invasion, but also gained considerable benefits from it. For example, in the research and utilization of new energy sources, Earth's humans obtained a large amount of energy crystals from the continent of Karen. These energy crystals possessed various abilities, and people devised all sorts of ways to utilize them.

For example, a research institute under the Magic Financial Investment Company designed a cooling pendant the size of a matchbox using water-attribute energy crystals. Wearing this pendant will keep the wearer at a constant temperature of 24 degrees Celsius, no matter how hot the weather. The water-attribute energy crystals are only the size of a fingernail, yet this pendant can theoretically operate for a hundred years.

These pendants are just one of many new things; Earth has now completely transformed from a technologically advanced plane into one where technology and magic coexist. Andres is presiding over the annual graduation ceremony at Hogwarts, but this year's ceremony is clearly different from previous years.

Previous graduation ceremonies were always lively, yet filled with farewells and reluctance. Although the magical world is small, Earth is vast. Meeting up is both difficult and easy, but this year is different.

This year, there was less reluctance to part ways than in previous years; it felt more like summer vacation, with everyone discussing what subjects they would choose to study after the start of the new semester. Indeed, apart from a few who went out to work, most of this year's graduates chose to pursue further studies on the continent of Karen.
