Nie Yan tragically realized that no matter where he went in the First Military Academy, he attracted a lot of attention, and whispers frequently reached his ears.

Although depressed, he was also helpless.

Since the challenge was set for a month later, Nie Yan hadn't considered whether to accept it yet. He was still a little confused about Ares Lei Su's intentions. If Ares Lei Su wanted to challenge him, why set the time a month later instead of now? What Nie Yan didn't know was that Lei Su was currently undergoing high-intensity training, and he simply didn't dare to fight Nie Yan in the short term. If the students of the First Military Academy knew about this, who knows what they would think.

He continued attending classes as usual; life at the school was mostly uneventful.

When he entered the game that night, Nie Yan helped the Niu Ren Tribe acquire fifty-six flying mounts. Once the injuries on these flying mounts had fully healed, the Niu Ren Tribe would have about a hundred flying mounts.

The Niu Ren Tribe was actively preparing for war, gathering hundreds of thousands of people and hundreds of catapults from the alliance to pressure Colt City with overwhelming force. The mountains and plains were filled with people from the Niu Ren Tribe alliance, which could be described as overwhelming.

There were more than twenty guilds in Colt City, at least ten of which had been acquired by the Monee Conglomerate, which controlled more than 70% of the fortresses in Colt City. These guilds, when gathered together, were a force to be reckoned with.

The Niu Ren Tribe's three hundred Frost Ironclad Catapults and one hundred Ballistic Catapults advanced slowly across the plains, a sight that was truly chilling.

Seeing the Niu Ren Tribe's massive force advancing towards them, the guilds of Colt City panicked and quickly mobilized their forces to defend.

The dark cloud of war loomed over Colt City.

The Monee Conglomerate was mobilizing its forces to attack Carol City, to strike a heavy blow against the Niu Ren Tribe. Their preparations were not yet complete, but the Niu Ren Tribe was one step ahead of them, catching them off guard.

Sara Fortress, Colt City. This was the fortress of the Dragon Excellence Guild, the second-largest guild in Colt City. This fortress occupied a vital passage to Carol City, so the Monee Conglomerate spent a lot of gold to upgrade the fortress's defenses. The walls, over twenty yards high, gave off a great sense of oppression.

Inside the walls, there were about seventy to eighty thousand players stationed. In addition, three teleportation arrays were opened inside the fortress. Once the battle began, more than a hundred thousand people from more than a dozen guilds in Colt City would be immediately transported over. Five cannons were set up on the city walls, but the firepower of these magic cannons was still somewhat different from that of the goblin magic cannons. The number was also too small, and compared to the Niu Ren Tribe's catapult troops, they could simply be ignored.

More than a hundred ballistic catapults slowly approached the walls of Sara Fortress. The magic cannons on the walls of Sara Fortress began to attack, firing a few sporadic shells, blasting apart two ballistic catapults. Many shells missed their mark and landed on the open ground.

More than a hundred ballistic catapults were lined up outside the fortress, completing their setup. The players next to the ballistic catapults moved the boulders onto the catapults.

Nie Yan stood on a hill near the plain, looking down. The mountains and plains were filled with the Niu Ren Tribe's troops. The Sara Fortress in the distance did not seem difficult to conquer. His heart was filled with pride. The process of conquering the entire Greenland Empire would begin with this Sara Fortress!

"Begin the attack!"

With Nie Yan's order, hundreds of boulders were thrown into the air, flying towards the Sara Fortress in the distance. They fell whistling down, and Sara Fortress was instantly thrown into chaos. Rubble flew everywhere, and part of the city wall collapsed with a bang. The five magic cannons were smashed into dust.

Sara Fortress groaned and trembled under the attack of the ballistic catapults. After a few rounds of salvoes, the city walls collapsed into ruins.

The entire fortress was like a maiden stripped of her clothes, naked before the players of the Niu Ren Tribe.

Under Nie Yan's command, they did not immediately charge up, but relied on the catapults to advance all the way, minimizing casualties as much as possible.

The players inside Sara Fortress were bombarded by the Ironclad Catapults again and again, and were almost wiped out.

This was an overwhelming victory with no suspense. There was no need for Nie Yan to take action. He believed that the Niu Ren Tribe's troops would turn all the fortresses of Colt City into ruins in a very short period of time.

The Niu Ren Tribe was completely declaring war on the Monee Conglomerate. He didn't know what kind of reaction the Monee Conglomerate would have next. The Monee Conglomerate would definitely not sit still and wait for death.

While paying attention to the battle situation, Nie Yan began to study the improvement plan for the Headless Horseman Doro's Mounted Crossbow. He had already had his slave Delphinia copy a copy of the crossbow improvement plan drawings, then took out one of them and learned it.

He asked the players of the Niu Ren Tribe to collect some metal materials and began to modify the Headless Horseman Doro's Mounted Crossbow.

The Headless Horseman Doro's Mounted Crossbow was very delicate. The crossbow body was made entirely of metal and was exceptionally hard, giving off a shocking sense of power. The only drawback of the Headless Horseman Doro's Mounted Crossbow was its weight. It took a lot of effort to hold it up with both hands, and if one's strength didn't reach a certain level, they couldn't even lift the crossbow.

According to the drawings, he made some subtle modifications to the mounted crossbow, replacing the middle section of the mounted crossbow with the most elastic Pali alloy. Pali alloy was a very rare metal, and the Niu Ren Tribe's guild warehouse only had two or three pieces of it. In addition, the steel wire used for the mounted crossbow also had to be replaced.

Nie Yan was very meticulous in every task. His mechanics, forging, and other skills had reached the master level, so doing these things was quite easy.

After the players of the Niu Ren Tribe took down Sara Fortress, they continued to advance to the next fortress. Nie Yan followed behind the main force, concentrating on modifying the mounted crossbow.

After about five or six hours, the appearance of the Headless Horseman Doro's Mounted Crossbow had changed greatly. The front end was shaped like a shuttle, and the curved bow body was full of elasticity. The softness was higher than before, but once it was tightened, the hardness immediately increased greatly. At the same time, due to the use of Pali alloy, the weight of the mounted crossbow was greatly reduced, making it much more convenient than before.

The imposing appearance of the Headless Horseman Doro's Mounted Crossbow gave people a very shocking visual impact.

To truly completely modify the mounted crossbow would take at least another five or six hours, and there was also a lack of some rare metal materials. Although ordinary materials could be used as a substitute, the modification of the mounted crossbow had to be completed in one go, and it had to be done to the best of his ability. Otherwise, it would take a lot of effort to modify it again in the future.

Nie Yan asked Guo Huai to send people to the market to find those metals.

He didn't know what the attributes of the modified mounted crossbow would be like.

Looking at the unfinished mounted crossbow, he suddenly thought, since the mounted crossbow could be modified, then the crossbow bolts could also be modified!

The damage that could be caused by ordinary crossbow bolts was extremely limited. If he could find a way to create some powerful crossbow bolts, he could greatly increase the attack effect.

Nie Yan began to use Pali alloy to make arrows, melting and forging them.

Nie Yan thought of several plans. The first was to make the arrowhead into a triangular pyramid shape with a blood groove, which could cause a certain amount of bleeding effect once hit. The second was like a bone spur, with a mechanism attached. It could cause a hooking effect when it was扎 into the flesh, making it impossible to pull it out again. The third was a pointed shuttle shape, with the arrowhead filled with venom, which could cause a very strong poison effect.

In addition to these three types of arrows, he could make other types when he had ideas in the future.

Thinking of this, Nie Yan began to make them. For him, making this kind of arrow didn't take much effort, and he could realize these ideas very easily.

Unfortunately, these three types of arrows could not be completely merged into one, otherwise, the power would not be guaranteed, and it would be very cumbersome and redundant. They could only be processed separately. Different arrows could be used in different situations.

After a while, a triangular pyramid-shaped arrow was made. He engraved many runes on it, which could greatly enhance the arrow's lethality.

System: You have invented an arrow, please name the arrow.

Nie Yan thought for a while and named it Bleeding Arrow.

System: You have successfully made a Bleeding Arrow, gaining 580 skill proficiency points in Forging, Mechanics, and Alchemy.

He looked at the attributes of this Bleeding Arrow.

Bleeding Arrow: Attack +800, with a 30% bleeding effect, lasting for five minutes.

The effect of this Bleeding Arrow was very strong, especially the bleeding time, which actually lasted for five minutes, which was simply amazing.

Nie Yan didn't expect that the blood groove design would have such a big effect, and the attack power was also very good.

In addition to the Bleeding Arrow, Nie Yan also made the other two arrows, naming them Bone Spur Arrow and Poison Arrow respectively. There was no need to be too particular about these names, as long as the things were practical. Nie Yan asked Guo Huai to get a large pile of metal and kept making arrows. One arrow after another was made by him. The manufacturing process was quite simple.

The Bone Spur Arrow could cause a certain degree of disability effect to the opponent's body when射入 it, and the Poison Arrow could cause poison damage.

Nie Yan made about one hundred and twenty Bleeding Arrows, more than two hundred Bone Spur Arrows, and more than one hundred Poison Arrows in total.

It took about three hours to make these things in total. Anyway, he had mastered the process and didn't lack materials, so he could make more in his spare time in the future.

Nie Yan gathered all these arrows, put them in a quiver, threw them into his backpack, and could use them when he encountered a situation in the future. After the Headless Horseman Doro's Mounted Crossbow was successfully modified, his ranged attack ability would be greatly improved.

When Nie Yan was making arrows, the Niu Ren Tribe had already broken through eleven cities in a row, beating the Colt City guilds until they were running around like rats. They were all depressed and wanted to die. When they saw the Niu Ren Tribe's troops coming over, they hated that their parents hadn't given them two more legs.
