The swordsman's left hand went numb and he could barely make a fist. He thought to himself that this kid was not easy to deal with.

But he was, after all, a master of the Transformation Realm, and naturally possessed his arrogance.

"My name is Zhao Feng. Chang Fa is covering the rear. Kid, you must be Lan Hua, right?"

"That's right, it's me! It seems my name is quite famous!" Lan Hua laughed.

"Hand over the black box, and I might spare your life!"

Zhao Feng chuckled, "You think you can spare my life when you're just a weakling at the Pure Yuan Realm?"

He made a sword shape with his right hand fingers together, and with a slight movement, the flying sword hovered above his head.

"I'll take this opportunity tonight to kill you and eliminate this great threat! I won't spare your life!"

After saying that, Zhao Feng drew his sword technique, and the flying sword, carrying a beam of light, shot swiftly toward Lan Hua.

Lan Hua sneered and shot an arrow.

One arrow is shot, four arrows appear; this is the fourth move of the Invisible Arrow Technique, from all directions!

bite!

An arrow struck the tip of the flying sword, disrupting its trajectory and startling Zhao Feng.

The other three arrows were aimed at Zhao Feng, leaving him with nowhere to retreat.

Zhao Feng cursed himself for being careless. It was too late to recall his flying sword to defend himself, so he could only move his sword fingers with both hands to form several arrow curtains around his body.

boom!

The sword curtain shattered one after another, and the three invisible arrows of light also shattered together.

"As expected of a sword cultivator from the Immortal Sword Sect!" Lan Hua thought to herself.

Zhao Feng's face turned cold. "You're courting death!"

With a flick of his wrists, he summoned a flying sword that soared above Lan Hua, condensing into a massive sword beam that shot towards Lan Hua, determined to pierce her from head to toe.

Lan Hua was not afraid at all and fired a black iron talisman arrow from her bow.

The arrow was extremely fast, and Zhao Feng could no longer avoid its impact.

He already knew how powerful the black iron arrow was; if the two collided directly, his flying sword would definitely be torn open.

Others only expend one arrow, and once it's gone, it's gone. But it's different for him.

That flying sword was his natal flying sword, extremely complex to forge, and the most precious of all.

If the flying sword is damaged, Zhao Feng will be sad for several months.

boom!

The two immense forces collided, and Zhao Feng's flying sword was directly blasted away, a nick appearing on the blade, and it slipped out of his control.

No matter how he summoned them, the flying swords that were tumbling rapidly in the air could not return in time.

Lan Hua chuckled maliciously, seized the opportunity, and fired another black iron talisman arrow, aiming directly at Zhao Feng.

"not good!"

Zhao Feng was shocked. Even his flying sword couldn't withstand the black iron arrow, let alone himself.

However, since the flying sword was not being summoned, he had no choice but to use all his energy to condense a light sword in front of him and rush towards the black iron arrow.

boom!

The black iron arrow pierced through the light sword and struck Zhao Feng's heart.

Zhao Feng looked on in disbelief. "How is this possible? How could you, a weakling at the Pure Yuan Realm, kill me despite being at a higher level?"

Lan Hua snorted, "Sword cultivators are indeed powerful, but archery cultivators are not to be underestimated!"

"What a brilliant archer! My death was not in vain!"

Zhao Feng coughed up a mouthful of blood and collapsed to the ground.

Lan Hua came to his side, took off his storage ring, and took out the black box from it.

He accepted the rest without question.

Even mosquito meat is still meat; little by little, it adds up to a lot.

Lan Hua looked at the black box, and a bad feeling welled up in her heart.

The box wasn't big, just the size of a palm, square and quite ordinary.

However, he didn't know what was inside the box, and he dared not open it rashly, since the box had always been kept in the forbidden area.

"Things in the forbidden area are probably not good things!"

He recalled that many powerful demonic beasts were sealed in the forbidden area. "Could there be a demonic beast sealed in this box as well? But this box is a bit small!"

Lan Hua walked back. Since Jiang Xinghai wanted the box, he naturally couldn't take it.

If the Dan God Temple investigates and holds me accountable, I'll be in big trouble.

When he arrived at Jiang Xinghai's side, Chang Fa had already retreated and disappeared.

Although Jiang Xinghai successfully repelled the enemy, he also sustained numerous injuries.

His opponent was, after all, a master of the Overlord Blade Sect, whose Heartless Blade Technique was already quite accomplished. It was no easy feat to force him to retreat.

"Instructor Jiang, are you alright?"

Instructor Jiang shook his head and asked anxiously, "You came back so quickly, did that person get away?"

Lan Hua gestured with her right hand, and a black box appeared in her hand.

"Don't worry, Instructor Jiang, I've already taken care of that person!"

Jiang Xinghai was startled, as he was well aware of Lan Hua's cultivation level.

The ability to kill a Transformation Realm expert while only at the ninth level of the Pure Yuan Realm is astonishing, regardless of the method used.

Jiang Xinghai took the black box, his heart pounding with excitement, his hands trembling slightly.

Lan Hua asked curiously, "Instructor Jiang, what exactly is in this box?"

Jiang Xinghai shook his head and said, "I don't know either. Perhaps the key to refining the Longevity Elixir lies within this!"

Lan Hua frowned slightly. "Instructor Jiang, do you know the origin of this black box? Why did it appear in the forbidden area?"

Jiang Xinghai said, "There have always been rumors that there is a box in the forbidden area of ​​the back cliff, and that there is a great opportunity inside, but only the Palace Master may know what it is!"

Seeing that Jiang Xinghai remained motionless, Lan Hua already knew his plan.

"Instructor Jiang, are you planning to open this box right here?"

"Great, I can't wait any longer! I want to see right now if this box contains what I need!"

Lan Hua sensed that what was inside wasn't anything good, so she took a few steps back and slightly raised her right hand to prevent any accidents.

He felt that Jiang Xinghai was obsessed with the black box, and he figured that Jiang Xinghai wouldn't listen to his advice.

Jiang Xinghai placed the box on the ground, stretched out his right hand, and poured Yuan energy into the box.

The lid on the box slowly opened, and then a white mist rushed out and spread in all directions.

Lan Hua was startled and clapped her hands repeatedly, forcing back the white mist with several palm strikes.

But he was still not at ease, so he quickly set up a protective barrier to isolate the two of them from the fog.

Then, with a palm strike, the wind from the palm swept across and closed the lid of the box again, preventing the fog from spreading further.

Just then, several birds flew in from the sky, passing through the mist.

Almost instantly, the birds' eyes suddenly turned black, their bodies emanated a black aura, and then they went berserk.

Several birds flew towards Lan Hua and Jiang Xinghai, as if they had lost their minds.

"Huh? What's going on?"

Lan Hua struck out with her palm, and several birds were hit by the force of the palm, falling to the ground and occasionally opening their mouths to scream, their voices mournful and terrifying.

After a long while, the birds finally fell silent.

Looking at the scene before him, Jiang Xinghai murmured, "How could this be? Aren't there treasures inside?"

Lan Hua was also dumbfounded.

That white mist was so terrifying that birds that were only touched by a trace of it mutated and went berserk, becoming completely unrecognizable to their own kind.

This fog is ominous! It's eerie!

Lan Hua breathed a sigh of relief; thankfully, he had been prepared.

He knew nothing about the mist, nor whether the protective barrier was effective.

Lan Hua asked suspiciously, "If this fog is so poisonous, why would it be placed in the forbidden area behind the cliff? Why not just throw it away to prevent future trouble?"

Jiang Xinghai knew nothing about it.

Lan Hua asked, "Instructor Jiang, who told you that the contents of this black box could be used to refine the elixir of immortality?"
