Who told you to slay demons like this?

The indestructible beak of the Demon King Zhui Yi had been gathering strength for a long time. Just as he suddenly attacked, intending to completely kill this human genius.

Suddenly, an irresistible and powerful energy surged between this world.

A huge and dazzling golden light shone directly at Lu Lingjue. The huge inky black formation beneath him shattered quietly under the impact of the dazzling golden light, and then completely turned into dust.

All seven demon kings were attacked by the backlash of the golden light and were forced to retreat again and again by the force. The previously injured Ghost Centipede Demon King even vomited blood violently.

The Demon King Zhui Yi was so angry at this situation that his eyes were about to burst out. He was unwilling to give in. He did not retreat from his powerful attack and flew towards Lu Lingjue.

The Heavenly Master's magic to control demons was shattered, and the spiritual energy in his body surged wildly again.

Lu Lingjue didn't care too much. Facing the attack of the Demon King Zhui Yi, he instinctively summoned the spear that had long disappeared.

"boom!"

The red tasseled spear, surrounded by rolling lightning, went straight up to the sharp beak of the Demon King Zhui Yi. The deafening, violent shock wave swept across the entire sky in an instant.

Invisible huge waves rolled forward in the air, causing other demon kings to retreat one after another to avoid being affected.

Lu Lingxian's thin figure was tottering. He looked up and smiled knowingly at his sister who had broken free from the shackles and was once again invincible.

Afterwards, Lu Lingxian's beautiful eyes began to lose focus, his vision gradually blurred, he lost his mind, and the back of his head fell to the ground at a high speed.

"Master Lu!"

The Lu family soldiers behind him were in a panic and hurriedly fighting with other demon kings while rushing to support Lu Lingxian.

The moment Lu Lingjue felt the impact of the golden light, he knew it must be his younger brother who took action.

She knew her brother's strength. To be able to burst out with such power and smash the formation set up by many demon kings, he must have burned countless lives.

If a mortal man attempts to rule the world with his body alone, he will surely be met with a powerful backlash from heaven and earth.

She didn't dare look back, her eyes were red and filled with fierce murderous intent.

"kill!"

The spear was held upright, and after failing to hit anyone, he continued to swing it towards the Demon King Zhui Yi, who had been showing his fangs and claws and roaring endlessly before.

The situation on the front line seemed to be improving, but the situation in the city defense formation was not much better.

Countless monsters rushed forward one after another as if they had lost their minds and rushed madly towards the city defense formation.

Most of the demon slayers had already used up their energy-restoring pills, and were trying their best and gritting their teeth to maintain the defense formation.

"Ah I……"

A miserable voice broke the silence of the demon slayers.

Everyone subconsciously looked in the direction of the sound.

He was a demon slayer whose spiritual power was drained by the formation, and he had no more Qi-restoring pills to replenish his energy. His plump body was rapidly being drained by the formation, and all his flesh, blood, and internal organs were absorbed.

Only a shriveled piece of skin was left, attached to the thin bones, with empty eye sockets and a howl before death.

In order to maintain the city defense formation, he devoted all his spiritual power as a warrior, and even his flesh and blood, but was abandoned only after being completely drained of it by the formation.

Many demon slayers already knew that this would be their fate if the war dragged on.

But despite this, a hint of fear and unwillingness still flashed across their already numb eyes.

Can they really hold on?

The battle was still going on in the air. The sharp beak, the hardest part of the Demon King Zhui Yi's body, had already been broken into two pieces by Lu Lingjue's fierce attack.

"What are you standing there for? Come on together!"

The Demon King Zhui Yi ignored the fact that his words were exposed and looked at the several Demon Kings who were standing by and watching, feeling extremely angry.

Hearing the rebuke from the Demon King Zhui Yi, the other demon kings did not want to miss this good opportunity to attack the city, and rushed towards Lu Lingjue together.

Even though Lu Lingjue broke the seal, so what?

It is becoming increasingly difficult to maintain the formation. Even if Lu Lingjue can fight ten people alone and take the lead, can he really stop the demons below who are desperately attacking the city?

As long as the city defense formation is broken, Lu Lingjue will be doomed and powerless to recover.

Qin Xi observed the situation closely. Even though Lu Lingjue was a young genius with extraordinary strength, he could not withstand the attacks of eight demon kings.

The battle outside the formation inevitably fell into a stalemate, and it was difficult to determine the winner for a while.

The key to determining the outcome of this battle lies in how long the city defense formation can hold out.

However, at this time, several demon slayers whose blood and flesh had been completely sucked dry appeared one after another, and the crowd could no longer hold on.

Qin Xi himself was fine. He only needed to infuse a little demon essence to restore all his spiritual energy.

But the other demon slayers did not have Qin Xi's golden finger. Faced with the cruel demons attacking the city, they could only allow the city defense formation to absorb their energy madly.

Qin Xi gritted his teeth. Most of the demon slayers here were stationed at the border all year round to protect the peace of the Dashun Dynasty.

Although she was not familiar with them, she was only familiar with the people who came to support Rong Nancheng.

But when I think of these demon slayers, they were first led by Master Liaobi wrongly and suffered a massacre at the hands of demons, and they barely survived and waited for Lu Lingjue.

But at the moment of dawn, he fell into the abyss again.

If the demon slayers could not hold on and the ancient city formation collapsed completely, then even if Lu Lingjue turned the tide and defeated the eight demon kings, he would still be doomed.

A feeling of despair and powerlessness surged into my heart. The formation's demand for spiritual energy was truly too terrifying.

If I were to hold up the formation on behalf of the many demon slayers, I'm afraid I wouldn't have time to use the demon essence to restore my spiritual energy before I was completely sucked dry and turned into bones.

Never mind. There are still 4,500 points of demon essence left. I will deduce it first to see if I can reach the Golden Core Stage.

When he reaches the Jindan stage, perhaps he can rely on the Jindan stage strength and the replenishment of demon essence to support the city defense formation alone.

Qin Xi injected two thousand points of demon essence without hesitation and continued to deduce the Purple Mansion Immortal Scripture.

[In the first year, you continue to practice the Purple Mansion Immortal Scripture]

[In the eighth century, the golden elixir has become increasingly clear and translucent. Now the golden elixir in your body is the size of an egg.]

[In the 1,500th year, you formed a round, plump, and powerful golden elixir]

[In the 1800th year, after thousands of years of seclusion, you finally succeeded in condensing a clear golden elixir that seemed to be nothingness, invisible and intangible]

[In the 2,000th year, the golden elixir becomes more and more substantial]

With the end of two thousand years of deduction, the spiritual energy in Qin Xi's body surged rapidly, which was a sign of a breakthrough.

It took Qin Xi, the deduction device, two thousand years to gradually break through the bottleneck and continuously improve and consolidate the golden elixir.

The originally tangible and material golden elixir was completely transformed into a golden elixir without any substance, invisible and yet indestructible.

For thousands of years, although my comprehension in the deduction device was a little poor, the accumulation of golden elixir did not require too much comprehension.

The accumulation of years has allowed the golden elixir to accumulate too much. Qin Xi clearly realized it when he felt the surging spiritual energy in his body.

With my current condition, I can only sustain the city defense formation for ten breaths.

"All of you stop and meditate on the spot to restore your spiritual energy!"

"I'll hold up the city defense formation!"
