I cultivate the Chaos Technique

Looking at the horrific battlefield before him, Zhang Yifan felt a surge of responsibility. He knew he couldn't stand idly by; these black-armored soldiers had fought valiantly to protect Anlin Pass and were now in dire straits. He had to lend a helping hand.

Without hesitation, Zhang Yifan drew his longsword from his waist, and in a flash, charged towards the battlefield. His speed was incredible, like a bolt of lightning streaking across the desolate land. The demonic beasts engaged in battle with the black-armored soldiers were completely unaware of Zhang Yifan's approach.

Zhang Yifan charged into the horde of demonic beasts, his longsword flashing, unleashing a torrent of sword energy. Each strike contained immense power, instantly slaying several beasts. The black-armored soldiers, seeing help arrive, felt a surge of hope.

"Brothers, someone's coming to help us! Hold on!" a soldier in black armor shouted.

While slaying the demonic beasts, Zhang Yifan observed the situation on the battlefield. He discovered that these demonic beasts were numerous and their strength was not to be underestimated. In particular, the enormous demonic tiger was incredibly powerful; the flames it breathed could instantly incinerate a person.

Zhang Yifan knew that to rescue the black-armored soldiers, he had to deal with the demonic tiger first. He flashed forward, charging towards the tiger. Seeing Zhang Yifan charging towards it, the demonic tiger's eyes flashed with rage. It opened its blood-red maw and once again spewed forth raging flames.

Zhang Yifan was prepared; he cast a defensive spell, forming a sturdy shield in front of him. The flames struck the shield, producing a loud noise, but they could not penetrate its defenses.

Taking advantage of the opportunity, Zhang Yifan approached the demon tiger and thrust his longsword fiercely towards its eye. The demon tiger reacted quickly, raising its paw to try and block Zhang Yifan's attack. However, Zhang Yifan's swordsmanship was extremely sharp; his longsword instantly pierced through the demon tiger's paw and struck its eye.

The demonic tiger let out a painful roar, twisting its body frantically, trying to escape Zhang Yifan's attack. Zhang Yifan gripped his longsword tightly, continuously channeling his power, attempting to kill the demonic tiger completely.

While Zhang Yifan was fiercely battling the demonic tiger, the black-armored soldiers were also fighting valiantly against attacks from other demonic beasts. Seeing Zhang Yifan's bravery, they were greatly encouraged, and their fighting strength instantly increased significantly.

After a fierce battle, Zhang Yifan finally succeeded in slaying the demon tiger. The demon tiger's corpse fell to the ground with a loud thud. Seeing their leader killed, the other demon beasts immediately fell into chaos.

Taking advantage of the opportunity, Zhang Yifan shouted loudly, "The demon leader is dead! Let's all kill him!"

Hearing Zhang Yifan's shout, the black-armored soldiers were greatly encouraged. They fought bravely and killed the monsters that had fallen into chaos.

The battle was finally over. The black-armored soldiers sat exhausted on the ground, their bodies covered in wounds, but their eyes were filled with gratitude and respect.

"Thank you so much for saving us! If it weren't for you, we would surely be dead today." A black-armored general walked up to Zhang Yifan and bowed respectfully.

Zhang Yifan waved his hand slightly and said, "No need to be polite. I just happened to be passing by and saw that you were in trouble, so I offered to help."

The general said, "We will forever remember your great kindness. May we ask your honorable name?"

"My name is Zhang Yifan," Zhang Yifan replied.

The general said, "So it is Benefactor Zhang. We, the soldiers of Anlin Pass, will forever remember your kindness today. May I ask what Benefactor Zhang's plans are next?"

Zhang Yifan thought for a moment and said, "I am new to Anlin Pass and not familiar with this place. I wonder why this monster suddenly attacked Anlin Pass?"

The general sighed and said, "These monsters have always been active in the border areas, frequently harassing our Anlin Pass. But the scale of their attack this time is truly unprecedented. We suspect that there may be a more powerful force behind them."

Zhang Yifan frowned and said, "An even more powerful force? Could it be other tribes of the demon race?"

The general said, "That's possible. But we don't know the specifics yet. The city lord of Anlin Pass is trying to figure out how to deal with this crisis."

Zhang Yifan said, "I want to see the city lord; perhaps I can be of some help."

The general said, "Very well, I will take my benefactor to see the city lord right away."

Zhang Yifan followed the general to the city lord's mansion at Anlin Pass. Inside, the city lord sat in his study, his brow furrowed in worry. Hearing that someone was requesting an audience, he ordered the general to bring Zhang Yifan in.

The city lord looked at Zhang Yifan and asked, "Are you the benefactor who saved my soldiers on the battlefield?"

Zhang Yifan nodded slightly and said, "You're too kind, Lord City Lord. My name is Zhang Yifan. I'm new to Anlin Pass. When I saw the monsters attacking Anlin Pass, I stepped in to help."

The city lord said, "Zhang Engong is very righteous. On behalf of all the people of Anlin Pass, I thank you. I wonder what Zhang Engong's opinion is on this monster attack?"

Zhang Yifan said, "I think there might be a more powerful force behind this monster siege. We must find out this force as soon as possible, otherwise Anlin Pass will face an even greater crisis."

The city lord nodded and said, "I share the same concerns. But we don't have any clues yet. Moreover, although Anlin Pass's defensive formation is powerful, it can't be maintained indefinitely. If the demonic beasts continue their attacks, we will eventually be unable to hold out."

Zhang Yifan said, "Lord City Lord, we can send people to scout out the movements of the demonic beasts and see if they have any other plans. At the same time, we can strengthen the defenses of Anlin Pass and prepare for any possible situation."

The city lord said, "You're right. I will send people to scout the movements of the monsters. As for strengthening our defenses, we've been working hard on that as well. But our resources are limited, and it's difficult to sustain this in the long run."

Zhang Yifan thought for a moment and said, "Lord City Lord, when I was in Yunzhou, I heard about a method that could enhance defensive formations. Perhaps we can give it a try."

The city lord's eyes lit up, and he said, "What method? Tell me quickly."

Zhang Yifan said, "This method requires some special materials, such as spirit crystals and black iron. We can use these materials to reinforce the defensive formation, making it more robust. At the same time, we can also set up some traps and mechanisms on the defensive formation to increase the difficulty for the monsters to attack the city."

The city lord said, "This method is good. But where will we find these materials?"

Zhang Yifan said, "Yuzhou is a vast region with abundant resources. I believe we can definitely find these materials. We can send people to nearby mines and markets to search, or exchange them with other forces."

The city lord said, "Very well, I will send someone to do it right away. Zhang Engong, your help to Anlin Pass has been immense. If we can overcome this crisis, I will reward you handsomely."

Zhang Yifan said, "Lord City Lord, you don't need to be so polite. I'm just doing my part."

In the days that followed, Zhang Yifan and the soldiers of Anlin Pass worked together to strengthen the pass's defenses. They sent people to find materials, set traps and mechanisms, and kept a close watch on the movements of the monsters.

After a period of effort, the defenses of Anlin Pass were greatly improved. The demonic beasts, after several unsuccessful attacks, temporarily ceased their assault, seemingly waiting for something.

Zhang Yifan knew that the demonic beasts wouldn't give up easily. They were definitely plotting something bigger. He reminded the city lord to remain vigilant and be prepared for any eventuality.

Just then, a scout rushed over and reported to the city lord: "My lord, we have discovered a mysterious group in the border region. They are moving around mysteriously, and we don't know what they are doing."
