Wang Kai’s exclamation made the others slightly amazed. In fact, most of them couldn’t understand what this content was, but Wang Kai had a certain talent, so he was able to comprehend the descriptions inside.

"Great, Wang Kai, I like your way of speaking. Come on, let you lead this small team, and achieve results within a few days. We’re still counting on this joint trick to provide our troops with a decisive advantage in winning and losing."

The vice-captain smiled at Wang Kai and entrusted him with the important duty.

"This... me? I... I will give it a try."

Wang Kai wasn’t the type to shy away from challenges, so after realizing that the leadership of this vital team had been entrusted to him, he was taken aback but didn’t refuse.

In the subspace, Jia Yan silently witnessed all of this.

He didn’t intervene too much in what was happening inside, nor did he provide guidance because he needed something that could be practiced by the troops, not teaching one-on-one, which wouldn’t be efficient even if Jia Yan spent a lifetime.

On the first day, Wang Kai and a group of new joint method trainees were deeply pondering the joint trick brought by Jia Yan this time.

Because they were people who had studied the Yin-Yang Dao, actually, after carefully reviewing it, they realized that the joint method’s Yin-Yang Dao usage, and the new cultivation method handed over to them, were completely compatible.

It’s truly seamless.

"Alright, the first day has passed, I believe you have grasped this joint method, right? Such a great tactic, I’m very pleased we are the first users."

On the second day, Wang Kai gathered all the cultivators together, and then he began collaborating with several of them.

Because everyone had at least reached the level of Heavenly strong, their energy was different from ordinary creatures. Even though many people stayed up all night reviewing the secret book yesterday, they were only slightly tired, far from affecting actual collaboration and combat power.

Wang Kai was the same; he reviewed the joint trick method repeatedly yesterday. This united method shocked and impressed him, with an urge to quickly practice with other teammates to see the actual effect.

Many people had similar thoughts because they saw the terrifying nature of the trick from the description and introduction, and it’s possible that the effect might be unbelievable even to themselves.

Boom!

When a group of heavenly creatures joined together to create joint energy of the Yin-Yang Dao, bombing the entire starry sky with thunderous sounds, seemingly vibrating even the subspace, they were completely amazed.

Although they expected a great effect, they never anticipated the effect would be this powerful.

"This... our joint attack actually has such an effect. This combat power probably has the strength of dignitaries, right?"

Considering that the creatures and soldiers in Wang Kai’s team only had the power of a Heavenly level, above which there is a Star Space Level presence, and then there’s Sovereign level. Reaching Sovereign level strength makes a creature a significant strong one by itself.

But the attack that these strong ones can deliver, Wang Kai’s group of heavenly beings actually joined forces to produce a similar combat power?

"Oh my... this..."

A group of heavenly creatures could not believe their eyes.

Heavenly creatures cannot stand against dignitaries, no matter how many come; one hundred is a dead end, one thousand is not enough for one dignitary. Yet now, they merely have dozens of Heaven-level beings delivering Sovereign level strength?

This was beyond belief.

"Continue, this is just the first joint trick. Let’s try other tricks next, maybe there will be other surprises."

Even though this trick was enough to make a group of heavenly beings happy, they were still extremely looking forward to seeing what effects the other methods underneath might have.

However, it turned out that Jia Yan created these joint tricks without having every trick cause a groundbreaking effect.

In fact, Jia Yan considered the varying quality of soldiers, so he needed more balance and consideration, thus his united method was only refined to twenty patterns.

Don’t underestimate these mere twenty patterns; they include attack formations, group movement formations, and defense, gathering, sacrificing attacks, among others.

Among these numerous methods, the most amazing one is the cooperation with an existing small battleship, single-person Sky-grade battleship, which, when paired with their joint methods, can utilize technology weapons to combine strength and joint power, plus technology weaponry, creating a force comparable to large battleships.

This is very terrifying.

"Great, it’s so smooth. Those of us who studied Yin-Yang Dao mastered this battle method within just a few days. It’s worthy of being specially crafted for warriors."

Wang Kai and his group of subordinates fully mastered these battle joint methods.

"Alright, let’s go back and report, then I guess it’s time for our group to showcase this tactic for the first time in battle, are you scared?"
