Wan Liuchuan was a little surprised to see this, but seeing the anxiety and tension in Wan Lei's eyes, he figured Wan Lei wasn't there to kill him.

Wan Liuchuan didn't resist, and Wan Lei rushed up to him, the two colliding fiercely.

Wan Lei hugged him tightly, and seeing the terrifying sword light attacking from behind, he instinctively used Lei Dun (Lightning Escape), flashing to a distant spot on the left.

Standing in the distance, Wan Liuchuan saw the terrifying sword energy flash past and explode, and he was also filled with lingering fear. Fortunately, Wan Lei had reacted quickly, or he would have died under Duanmu Feng's sword.

"Thanks."

Wan Liuchuan said, looking at Wan Lei.

Seeing Wan Lei save Wan Liuchuan twice, Duanmu Feng was so angry that his blood vessels were about to burst. At this moment, he felt a bit like Zhou Tai.

"You little bastards, give me your lives!"

Duanmu Feng's sword tip condensed water droplets, and a cloud of water mist gathered around his entire sword.

With a wave of his treasured sword, Duanmu Feng sent raindrops raining down on Wan Lei and Wan Liuchuan.

Seeing this, Wan Lei and Wan Liuchuan immediately summoned their respective thunderclouds, bringing down a sea of lightning to protect themselves and jointly resist the incoming raindrops.

After a series of crackling sounds, the raindrops were all blocked by Wan Lei and Wan Liuchuan, but they were not feeling well. The mere shock of their cultivation base was enough to make them suffer.

"Lei-di, we can't confront this old thing head-on. We have to think of a way. I see that your thundercloud is a bit strange, even more powerful than mine. Why don't we combine our thunderclouds into one and use the power of thunder together to deal with him?"

Wan Liuchuan said, looking at Wan Lei.

"Okay."

Wan Lei nodded without hesitation, which surprised Wan Liuchuan.

He knew that if the two of them combined their thunderclouds, it would be equivalent to merging their powers. If Wan Liuchuan had even the slightest evil intention, he could manipulate those powers to turn against Wan Lei, leaving him with no place to be buried.

"You trust me that much?"

Wan Liuchuan asked.

"You're not stupid. If I die, you won't be able to deal with Duanmu Feng alone, and you'll die too."

Wan Lei said bluntly.

In fact, Wan Lei was more aware of the danger than anyone else. He agreed to Wan Liuchuan not because he trusted him, but because of his confidence in himself.

He was confident that he was far superior to Wan Liuchuan in manipulating lightning. If Wan Liuchuan had any evil intentions, he was confident that he could seize control of all the lightning and kill Wan Liuchuan in return.

"Okay, if we can escape this time, I'll remember this favor. During the heir competition, I won't kill you."

Wan Liuchuan said proudly.

Wan Lei smiled wryly in his heart. What a proud person. By then, who would spare whom was still uncertain.

The two manipulated their thunderclouds, and the two clouds merged together. The thunder of cultivation and the thunder of nature merged together, transforming into a thundercloud that was even larger than the previous two combined.

The thundercloud blotted out the sun, and the entire battlefield dimmed.

"That old thing is coming, let's get him!"

Wan Liuchuan cursed angrily, swung his long saber, and slashed straight at Duanmu Feng.

Wan Lei was not afraid either, and followed Wan Liuchuan to attack.

Wan Liuchuan slashed his saber at Duanmu Feng's sword. The huge thundercloud provided him with extremely strong combat power, allowing him to unleash power far exceeding the peak of the Foundation Establishment stage. This saber actually forced Duanmu Feng back three meters.

Duanmu Feng was shocked by Wan Liuchuan's sudden increase in power, but before he could think too much, Wan Lei had already arrived.

Seeing Wan Lei raising his hammer and attacking him, Duanmu Feng sneered. He didn't believe that Wan Liuchuan could become stronger, let alone that Wan Lei, a mere lower-level Foundation Establishment cultivator, was worthy of fighting him.

But how could he have imagined that just as Wan Lei was about to rush in front of him, he suddenly disappeared with a whoosh.

Before Duanmu Feng could be surprised, he heard a loud thunderclap, and then his whole body was in excruciating pain and paralyzed.

Wan Lei was very clever. He first pretended to attack Duanmu Feng to attract his attention, and then used lightning to attack him.

However, this thunderbolt was not the end. He wanted to take advantage of Duanmu Feng's paralysis to launch another sneak attack.

Wan Lei used Lei Dun (Lightning Escape) to come behind Duanmu Feng, then raised his hammer and smashed it towards Duanmu Feng's head.

Duanmu Feng was paralyzed and unable to dodge at all. Wan Lei's hammer hit him squarely, causing Duanmu Feng's head to buzz and fall into a state of double bewilderment.

Seeing this, Wan Liuchuan would of course not let go of such a good opportunity, and immediately stabbed his saber towards Duanmu Feng's dantian.

Duanmu Feng was, after all, a Core Formation expert. His physical body was strong and his reaction was extremely fast. Just as Wan Liuchuan's saber tip was about to pierce his dantian, he barely tilted his body, and Wan Liuchuan's saber pierced next to his dantian, only breaking a layer of skin without causing him too much damage.

On the contrary, Wan Lei's lightning and hammer combo had caused him considerable injuries.

"Wan Liuchuan, are you okay? You couldn't take advantage of such a good opportunity. Can't you use a sword? Sabers are for chopping, not for stabbing!"

Seeing that Wan Liuchuan had failed to injure Duanmu Feng despite such a good opportunity, Wan Lei couldn't help but scold him angrily.

"Core Formation experts have been tempered by the heavenly tribulation, and their physical bodies will become stronger. It's normal that I can't pierce it."

Wan Liuchuan lived up to his name as a magnanimous and modest gentleman. He was not angry even when Wan Lei scolded him like this, but instead remained calm.

He truly achieved a state of being unfazed by honor or disgrace.

Wan Lei had no time to scold him. At this moment, Duanmu Feng had recovered and was swinging his sword at Wan Lei.

He hated Wan Lei to the core. At this moment, he no longer wanted to kill Wan Liuchuan. He had to tear this Wan Lei, who was like a loach, into pieces.

To vent his hatred!

"Wan Lei!!!"

Duanmu Feng roared and attacked Wan Lei, scaring Wan Lei so much that he immediately used Lei Dun (Lightning Escape) to get behind Wan Liuchuan.

He was kidding. He couldn't withstand a single blow from Duanmu Feng. It was enough to fight guerilla warfare and harass him. Did they really expect him to fight Duanmu Feng head-on?

Of course, this kind of thing should be left to someone with strength.

Seeing Duanmu Feng attacking, Wan Liuchuan gripped his long saber tightly with both hands, using the super strong combat power amplified by the thundercloud to engage in a fierce battle with Duanmu Feng.

Wan Lei was not idle either. He knew what he was good at, and relied on his thunder and speed to give Duanmu Feng a blow from time to time.

He always chose the right timing. Every time Wan Liuchuan was about to launch an attack, he would immediately flash behind Duanmu Feng and paralyze him with lightning, and then Wan Liuchuan would give him a heavy blow.

The two cooperated extremely well. Their combined combat power was not as good as Duanmu Feng's, but this kind of fighting style was too rogue, and Duanmu Feng had no chance to fight back at all.

One harassed and the other attacked. This rogue-like tactic was extremely effective. After more than an hour, Duanmu Feng was covered in injuries and was screaming and yelling in anger, with no demeanor of a strong person at all.
