After returning to the cave.
Zhang Yuhe arrived at the weapon-refining room next door.
The Nangong Immortal Clan treated these Golden Immortal cultivators who had been recruited quite well.
Not only does each person have a spacious, independent courtyard.
Moreover, the cave dwelling is fully equipped with all the necessary facilities.
The training platform, alchemy room, weapon forging room, and even the leisure area were all arranged neatly.
In the center of the weapon-refining room stands a tall platform.
Runes flashed on the platform.
Zhang Yuhe waved his right hand.
A large four-legged cauldron landed on the high platform in an instant.
He carefully took out the crystal-shaped innate spiritual material.
Then wave your right hand again.
A magnificent immortal sword slowly floated in front of him.
At the hilt of the sword.
It is engraved with the three small characters: "Galaxy. Gold".
This is precisely the metal-attribute immortal sword from the Nine Heavens Primordial Sword.
The complete Nine Heavens Primordial Sword set consists of nine immortal swords.
One weapon for each of the eight elements: metal, wood, water, fire, earth, wind, thunder, and ice.
Add a Hunyuan Sword, which has no attribute, to complete the set of natal magic weapons.
There is only one innate spiritual material.
In other words...
He can only choose one of the immortal swords to upgrade its quality.
In the very beginning.
Zhang Yuhe originally planned to first upgrade the Hunyuan Sword, which had no attribute.
In the entire set of natal magic treasures.
The Hunyuan Sword is the key to connecting the sword formations.
However, Zhang Yuhe was thinking...
His current goal is to improve the attack power of the sword formation.
Rather than the overall coordination of the sword formation.
so.
After careful consideration.
Zhang Yuhe set his sights on improving the metal-attribute immortal sword.
The tycoon's ruthless actions.
As long as the innate spiritual materials are integrated into the metal-attribute immortal sword.
The killing power of the entire sword formation will inevitably be greatly enhanced.
After making the decision.
Zhang Yuhe simultaneously threw the metal-attribute immortal sword and the innate spiritual materials into the four-legged cauldron.
As the hand seals were formed.
Instantly, scorching flames erupted from beneath the cauldron.
Zhang Yuhe sat cross-legged, silently observing the changes inside the cauldron.
It's different from refining immortal artifacts.
Forging immortal artifacts takes a very long time.
Even if Zhang Yuhe intervenes.
It takes him nearly half a year to forge a single immortal artifact.
However, integrating innate spiritual materials into finished immortal artifacts does not require too much time.
Generally speaking, it only takes two or three days.
However, the process of integrating innate spiritual materials into a celestial artifact is extremely complex.
It requires careful control and observation.
What if the integration fails?
Not only will innate spiritual materials be wasted.
Even the original immortal sword will be scrapped along with it.
You need to know.
This is his signature magic weapon.
If his natal magic weapon is damaged, he himself will also suffer extreme harm.
Therefore, Zhang Yuhe dared not be careless at all.
He focused all his attention on silently observing the changes inside the cauldron.
...
Time slowly passed.
On the third day of the beast tide.
The battle situation throughout the entire region has reached a fever pitch.
Some immortal cities are weak due to insufficient defenses.
It has been conquered by the Chaos Beasts.
Most of the cultivators in the city escaped using the teleportation array.
But there are still many people.
Because they were being watched closely by the Chaos Beast.
Even after the immortal city was breached, they were unable to escape.
The fate awaiting these monks.
There are only two types.
Or they could just self-destruct and end it all.
Either they fight to the very end, only to be captured by the Chaos Beasts and used as sacrifices.
However, the immortal cities under the Nangong Immortal Clan are still basically intact for the time being.
There is currently no immortal city; it has been breached by the Chaos Beasts.
...
Outside the Heavenly Palace City.
The battle has reached a critical point and is now at its most intense.
On the four walls of the Heavenly Palace City.
More than two hundred mid-grade Immortal-Slaying Cannons were firing continuously.
After each round of artillery fire.
A large number of Chaos Beasts will fall.
These mid-grade Immortal-Slaying Cannons are the culmination of countless years of accumulation by the Nangong Immortal Clan.
It was precisely because of these Immortal-Slaying Cannons.
Only then could they repeatedly repel the Chaos Beasts amidst the beast tides.
Even during the great calamity of immortals' demise.
The Heavenly Palace City has never been breached by the Chaos Beasts.
However, so many mid-grade Immortal-Slaying Cannons were firing continuously.
The number of crystal nuclei consumed is also an astronomical figure.
However, as long as we can defend the Immortal City, any amount of expenditure will be worthwhile.
The Nangong Immortal Clan can fully afford such expenditure.
Nangong Tianming stood on the city wall, looking at the dense horde of beasts outside the city.
He did not make a move.
In order to breach the immortal city of cultivators, the Chaos Beasts would try every possible method.
For example, a war of attrition.
Compared to the Chaos Beast.
Cultivators cannot withstand such depletion.
Once the immortal energy in the dantian is exhausted, the cultivator's combat ability can no longer be sustained.
Therefore, as long as the situation can be maintained.
Nangong Tianming will not make a move.
He wants to keep himself at his peak.
To prepare for any unexpected situations that may arise at any time.
However, Nangong Tianming did not make a move.
However, the other two Taiyi Immortal Lords of the Nangong Immortal Clan held nothing back.
They had already charged into the beast tide and were engaged in a fierce battle with the Chaos Beasts at the Taiyi Realm.
The Nangong Immortal Clan has three Taiyi Immortal Lords.
