#256Section 256

The Nangong Immortal Clan's treatment of us Golden Immortal cultivators who answered the call was quite good.

Not only did each person have a spacious independent courtyard,

but the facilities in the cave dwelling were also fully equipped.

Cultivation platforms, alchemy rooms, weapon refining rooms, and even leisure areas were arranged neatly.

In the center of the weapon refining room stood a tall platform.

Runes flickered on the platform.

Zhang Yuhe waved his right hand.

A four-legged cauldron instantly landed on the platform.

He carefully took out the crystal-shaped innate spiritual material.

Then he waved his right hand again.

A majestic immortal sword slowly floated in front of him.

On the hilt of the immortal sword, were engraved three small characters: [Galaxy. Metal].

This was the metal attribute immortal sword among the Nine Heavens Mixed Yuan Sword.

The entire set of Nine Heavens Mixed Yuan Sword consisted of nine immortal swords.

One each for the eight attributes of metal, wood, water, fire, earth, wind, thunder, and ice.

Plus one non-attribute Mixed Yuan Sword, forming a complete set of natal magic weapons.

There was only one innate spiritual material.

That is to say.

He could only choose one of the immortal swords to improve its quality.

In the beginning.

Zhang Yuhe originally planned to first improve the non-attribute Mixed Yuan Sword.

In the entire set of natal magic weapons.

The Mixed Yuan Sword was the key to linking the sword formation.

However, Zhang Yuhe thought.

His current goal was to enhance the attack power of the sword formation.

Rather than the coordination ability of the entire sword formation.

Therefore.

After careful consideration.

Zhang Yuhe set the improvement target on the metal attribute immortal sword.

Metal governs killing.

As long as the innate spiritual material was integrated into the metal attribute immortal sword.

The killing power of the entire sword formation would inevitably be greatly improved.

After making the decision.

Zhang Yuhe simultaneously threw the metal attribute immortal sword and the innate spiritual material into the four-legged cauldron.

As the magic incantation was cast.

Blazing flames instantly ignited from under the cauldron.

Zhang Yuhe sat down cross-legged, silently observing the changes inside the cauldron.

Unlike refining immortal artifacts.

Refining immortal artifacts requires a long time.

Even if Zhang Yuhe took action.

It would take him nearly half a year to refine an immortal artifact.

But integrating innate spiritual material into a finished immortal artifact did not take too much time.

Generally speaking, it only takes two or three days.

It's just that the process of integrating innate spiritual material into an immortal artifact is extremely complex.

It must be carefully controlled and observed.

In case the integration fails.

Not only will the innate spiritual material be wasted in vain.

Even the original immortal sword will be scrapped along with it.

You must know.

This is his natal magic weapon.

Once the natal magic weapon is damaged, he himself will also suffer extremely serious damage.

Therefore, Zhang Yuhe did not dare to be careless at all.

He devoted all his mind, silently observing the changes in the cauldron.

...

Time slowly passed.

When the beast tide progressed to the third day.

The battles in the entire area had all entered a fever pitch.

Some immortal cities, due to insufficient defense forces.

Had already been captured by Chaos Beasts.

Most of the cultivators in the city escaped through the teleportation array.

But there were still many people.

Because they were stared at by the Chaos Beasts.

They were unable to escape until the immortal city was breached.

The fate awaiting these cultivators.

There are only two.

Either directly self-destruct and be done with it.

Or fight to the end, be captured by the Chaos Beasts, and taken as sacrifices.

However, the immortal cities under the Nangong Immortal Clan are still basically intact for the time being.

No immortal city has been breached by Chaos Beasts yet.

...

Outside Heavenly Palace City.

The battle had completely entered a fever pitch.

On the four city walls of Heavenly Palace City.

A total of more than two hundred middle-grade Immortal Extinguishing Cannons had been firing continuously.

After each round of artillery fire.

A large number of Chaos Beasts would fall.

These middle-grade Immortal Extinguishing Cannons were the accumulation of countless years of the Nangong Immortal Clan.

It was by relying on these Immortal Extinguishing Cannons.

That they were able to repel the Chaos Beasts time and time again in the beast tide.

Even during the Great Immortal Fall Calamity.

Heavenly Palace City had never been breached by Chaos Beasts.

However, so many middle-grade Immortal Extinguishing Cannons, firing continuously.

The number of crystal cores consumed was also a complete astronomical figure.

But as long as the immortal city was defended, any amount of consumption was worth it.

The Nangong Immortal Clan could completely afford such consumption.

Nangong Tianming stood on the city wall, looking at the dense beast tide outside the city.

He did not take action.

In order to break through the cultivator's immortal city, Chaos Beasts would try every means possible.

For example, a war of attrition.

Compared to Chaos Beasts.

Cultivators could not withstand attrition at all.

Once the immortal essence power in the dantian was exhausted, the cultivator's combat capability could no longer be sustained.

Therefore, as long as the situation could be maintained.

Nangong Tianming would not take action.

He wanted to keep himself in peak condition at all times.

In order to cope with unexpected situations that could occur at any time.

However, although Nangong Tianming did not take action.

The other two Grand Unity Immortal Lords of the Nangong Immortal Clan did not hold back at all.

They had already rushed into the beast tide and were fighting against the Grand Unity Realm Chaos Beasts.
