At Kunmen Square, the atmosphere became tense after the arrival of disciples from various peaks.

Qin Xin stood aside and observed the scene. Apart from the main peak where Qin Xin was located, each peak had sent two teams to participate in the competition for the spiritual vein.

Among these teams, Qin Xin also saw many familiar figures, such as Yu Haoqian from the North Peak, Rong Zhihe from the West Peak, and Lu Chen from the South Peak. He had only met these people once before, but they were all on the Prodigy Ranking. Therefore, Qin Xin did not have much hope for the competition for the spiritual vein.

Just as Qin Xin glanced at the two teams on the North Peak, he saw a man with a red mark on his face who was also sizing up Qin Xin. When their eyes met, the man's eyes revealed murderous intent.

This sudden hatred left Qin Xin bewildered.

~~~~~~

"Now that the teams from each peak have all arrived, I won't go into the rules."

"However, I must remind everyone to stop when you've made a move, and not to kill anyone."

The Eighth Elder, dressed in black robes, opened his somewhat weathered eyes as the time had come, and his aged voice echoed throughout the Kunmen Square, "Three Peak Masters, please follow me to activate the Kunmen's protective array."

After speaking, the Eighth Elder produced several array flags in his hand. With a casual gesture, several stone pillars slowly rose from the ground in Kunmen Square, and a gate that seemed to lead to the underground world slowly appeared.

After nodding slightly, the three peak masters of Kunmen turned around and leaped down from the high platform. They sat around the stone platform, took out spirit stones, and placed them on the gate that had appeared. Instantly, the gate shimmered with azure light.

"Ten spiritual veins have already condensed within the protective formation. Once you enter, all you need to do is capture them and bring them back."

The Eighth Elder glanced down below, his aged voice sounding quite calm, "The spiritual veins are related to the concentration of spiritual energy in each peak, so if you want a better cultivation environment, then keep up the good work!"

As soon as the sound was uttered, the roars of the Kunmen disciples immediately resounded through the sky.

"Gentlemen, we from the North Peak will proceed first!"

The two teams from the North Peak took the lead, seemingly worried that the opportunity to seize the spiritual vein would be snatched away by other teams.

After the voice faded, several disciples from the North Peak filed into the gate, creating ripples in the air.

Following closely behind, the four teams from the South Peak and the West Peak also stepped straight in, as if the two peaks had reached an agreement to form a defensive alliance.

Yun Yi of Dongfeng Leige was not in a hurry at this time. After glancing at Shui Qingxi and the other female disciples of Fanhuage, he led Ji Ju, Han Yao and others into the gate in a hurry, as if he was worried about being followed.

"Qin Xin, would you like to come in with us?"

Shui Qingxi glanced indifferently at the Lei Pavilion group that had disappeared in front of the gate.

He turned to look at Qin Xin, who was still pondering to the side.

Qin Xin did not refuse, because after entering this underground world, everyone would be teleported to different places. So he followed Shui Qingxi and the others toward the gate.

"The teleportation point is located in the underground space beneath the many mountains of Kunmen, where many underground monsters live. You need to be careful after entering. If you encounter danger, just inject your true energy into the Kunmen identity crystal. The peak master outside will sense it and teleport you out directly."

Qin Xue walked straight up to Qin Xin and carefully reminded him, "The identity crystals between the peaks can sense the location of disciples from the same peak. Since you are from the main peak, you will be alone after entering. Here, this is for you."

After saying that, Qin Xue placed a jade pendant with petal patterns in Qin Xin's hand. "There is an array set up by our teacher on this jade pendant. When you get close to the disciples of the Mortal Flower Pavilion, it will flash red. After you enter, come and find us."

As soon as Qin Xin received the jade pendant, he felt a red light flash across it. Before he could say anything, the group had already stepped into the gate.

Surrounded by azure spiritual energy, Qin Xin felt as if he were being pulled by a mysterious force, and his whole body instantly plummeted. The feeling of weightlessness made his heart sink, and then his vision blurred for a moment before a burning spiritual energy lingered around his nose.

"Such rich spiritual energy from heaven and earth!"

Qin Xin used his martial spirit to detect the spiritual energy of heaven and earth floating in the air. As his spiritual sense wandered, Qin Xin discovered that the underground space was enormous, seemingly located beneath the various peaks of the Kunmen Sect.

Looking at the boulders and caves around him, Qin Xin was somewhat surprised, as these were all naturally formed.

"Huh!"

Upon probing with spiritual sense, it seemed to encounter resistance. After traveling less than twenty feet, the spiritual sense could no longer wander to other places, as the entire underground space was shrouded by a very powerful array.

"Is this the protective meridian array?"

Qin Xin exclaimed in surprise, his eyes scanning the surroundings. He saw many extremely solid rocks and molten lava pits that were already churning with heat.

After walking for a while, Qin Xin stopped to cultivate. It was unrealistic for him to try to seize the spiritual vein alone. After all, to subdue the spiritual vein, several people would need to work together to imprison it, while also preventing other teams from trying to steal it.

Finding a place rich in spiritual energy, Qin Xin sat down cross-legged. With his martial spirit rapidly circulating, he discovered that the Yang Fire Seed, which had been completely fused with the Heavenly Phoenix Martial Spirit Pattern, was directly floating on his martial spirit, greedily absorbing the surrounding fiery aura, as if the environment here was very suitable for its growth.

Qin Xin did not stop him. In a short while, his entire body was enveloped in an orange flame, and the originally golden Heavenly Phoenix Martial Spirit Pattern also had some orange marks.

Just as the Yang Fire seemed to reach saturation and directly merged into the Heavenly Phoenix Martial Spirit Pattern, transforming into an orange pattern, a mysterious feeling reached Qin Xin's heart, as if it were an instinct.

"Heavenly Phoenix Nine Nirvanas! First Nirvana!"

After Qin Xin uttered a low, guttural shout.

The Heavenly Phoenix Martial Spirit Pattern was instantly activated. Golden light mixed with orange flame patterns flowed rapidly, and an armor constructed of orange flames slowly took shape around Qin Xin's body.

With a slight tremor in his hand, the orange flames of the Nine Flames Battle Immortal Staff suddenly surged, and the surrounding temperature rose sharply in an instant.

"So the Heavenly Phoenix Martial Spirit Pattern can fuse with a fire seed! This Flame Armor is probably something even a martial artist at the ninth level of the Qi Opening Realm couldn't break with a full-force attack!"

Qin Xin looked down at the flame armor on his body, feeling the intense heat emanating from it, and murmured to himself.

Only martial artists at the Qi Sea Realm can condense their true qi into armor. Qin Xin is only at the sixth level of the Opening Aperture Realm. His orange flame armor is obviously a result of the Heavenly Phoenix Martial Spirit Pattern completely fusing the seed of Yang Fire.

After stopping the operation of the Heavenly Phoenix Martial Spirit Pattern, Qin Xin immediately felt that most of his true energy had been consumed. Although the Flame Armor could give him stronger defensive capabilities, the consumption of true energy was something that his current strength at the sixth level of the Aperture Opening Realm could not withstand.

After swallowing several Qi-restoring pills, Qin Xin quickly circulated his martial spirit to refine the medicinal power.

As the internal energy of the martial dantian gradually fills up, the dantian, which is constructed of both red and green energy, now shows a clear increase in red energy and a decrease in green energy.

Qin Xin didn't think too much about it. After getting up, he prepared to explore the underground space and see if he could find anything good.
