Sky Prison signed in for 20 years, I am invincible in the world

With a wave of Chu Xuan's right hand, a silver light flashed.

It was the silver dragon sword he obtained in Dayan Immortal Mansion.

This sword, Chu Xuan, was originally intended to be his own sword, but later Su Qianqian gave him a Xuanhong Sword of the level of a divine soldier, and this silver dragon sword was naturally reduced to a substitute.

In fact, in terms of casting materials alone, there is not much difference between the Silver Dragon Sword and other divine weapons. The Silver Dragon Sword is also made of priceless and rare divine mines.

It's just that Yinlongjian's luck was a little bit bad. He failed in the process of being promoted to a god soldier, and could only be reduced to a demigod soldier in the end.

This is also the reason why Chu Xuan is sure that the Silver Dragon Sword can be promoted to a divine weapon, because the foundation of the Silver Dragon Sword lies there.

If it is a weapon made of ordinary materials, even if it barely reaches the level of a demigod soldier, it may not be eligible to be promoted to a god soldier.

"A piece of magic weapon essence should be enough for Silver Dragon Sword to complete its final transformation."

As soon as Chu Xuan thought about it, the essence of the divine weapon also appeared in his hands.

Previously, the Thunder Spirit Spear and the Heaven-Swallowing Demon Gourd devoured the essence of the Divine Weapon without his help, because the Divine Weapon had spirits and could complete this process on its own.

The Silver Dragon Sword is only a demigod weapon, and has not yet been born with a real weapon spirit. Naturally, it cannot complete this process on its own, so it still needs Chu Xuan's help.

Under Chu Xuan's control, both the Silver Dragon Sword and the Divine Weapon Essence were suspended in mid-air, and the two sacred objects were shining brightly.

I saw strands of divine charm flowing, and divine patterns emerged one after another, rendering this temporary cave in front of me like a fairyland in the blink of an eye.

At the same time, an indescribably hot flame emerged in Chu Xuan's palm.

It's the sun that's on fire!

Under the burning of the real fire of the sun, the essence of the divine weapon gradually melted quickly, turning into a thin stream shining with colorful light, and slowly flowing into the silver dragon sword.

And at this time, the Silver Dragon Sword also trembled violently, as if the rain was coming after a long drought, and tried its best to absorb and devour the essence of the magic weapon, as if wasting even a tiny bit was a great sin.

As more and more magic weapon essences were successfully absorbed by the Silver Dragon Sword, the aura emerging from the Silver Dragon Sword became stronger and stronger.

This process does not happen overnight.

It took a lot of time even for the Thunder Spirit Spear and the Heaven Swallowing Demon Gourd to absorb the essence of a divine weapon, let alone a demigod like the Silver Dragon Sword.

In the blink of an eye, seven days passed.

When the last drop of magic weapon essence was completely devoured by the silver dragon sword, the energy of the silver dragon sword finally accumulated to the limit.

Just like a carp jumping over the dragon gate, it rushed into another brand-new level in an instant, and the power of a magic weapon visible to the naked eye rippled along with it.

Accompanied by the sound of cheering sword chants, the Silver Dragon Sword instantly turned into a silver flood dragon, circled around Chu Xuan's body, and then rushed straight into the sky.

"Rumble rumble—"

At the same time, the catastrophe followed.

Not only do human monks need to cross the catastrophe to reach a certain level of cultivation, but so do all creatures, and divine weapons are no exception.

When a weapon is promoted to a divine weapon, a weapon spirit will be born. To some extent, a divine weapon is no longer a pure weapon, but can be regarded as a different kind of life.

Thinking back when the Leiling Spear was promoted to a Holy Soldier, there should have been a catastrophe, but at that time in the Dayan Immortal Mansion, the Dayan Immortal Mansion blocked the breath of its promotion, so it took advantage of the loophole to escape the catastrophe .

It can't be regarded as escaping. When it crosses the catastrophe next time, the catastrophe it escaped last time will be counted on its head. At that time, the two catastrophes will be added together, which will be even more dangerous.

This is the so-called Skynet without any omissions!

Right now, Yinlongjian is only promoted in the wilderness, so naturally it doesn't have the same treatment as Leilinglance. The moment it completes its transformation, the catastrophe will come immediately.

In an instant, dark clouds were densely covered, and the power of violent thunder condensed and formed in the sky.

Standing in the canyon, Chu Xuan saw such a scene, his eyes did not fluctuate in the slightest.

Compared with the eighteen catastrophes he experienced not long ago, this catastrophe is really nothing.

"Is it possible to sign in during this catastrophe?"

Such a thought suddenly popped up in Chu Xuan's mind.

To be honest, this is not the first time he had such an idea, he had thought about it long before.

It's just that he didn't dare to take risks in the previous two tribulations.

After all, Heavenly Tribulation itself is already very dangerous, and he may not be able to bear it if something else happens.

Maybe he will be self-defeating, and instead of reaping the benefits, he will harm himself, so he won't even have time to cry.

But this time is different.

First of all, the power of the Silver Dragon Sword's Heavenly Tribulation is much smaller. If compared with his Heavenly Tribulation, it is at most at the level of the fourth or even fifth level of Heavenly Tribulation.

And his current strength is not what it used to be. As a genuine saint, he also has four magic weapons and a holy king-level puppet and many other trump cards. Even if something unexpected happens, he has enough strength to deal with it.

"Would you like to try it?"

"I don't dare to take the risk of the [-]th Heavenly Tribulation, but this level of Heavenly Tribulation shouldn't be too much of a problem!

Having said that, Chu Xuan still mobilized his whole body first, and several magical weapons were in a semi-activated state.

That holy king-level puppet was also controlled by the clone of the five elements, ready to go in the inner world.

There is also the Shenfeng flying boat that has just been refined, which also makes the space clone move ahead of time.

If the situation changes, he can also take this kamikaze flying boat to escape immediately.

After making full preparations, Chu Xuan turned into a black shadow and charged into the sky.

Since you want to sign in during the Heavenly Tribulation, you must first enter the scope of the Heavenly Tribulation.

And the moment Chu Xuan entered the range of Heavenly Tribulation, the terrifying thunder energy immediately exploded.

Heavenly Tribulation, who was originally staring at the Silver Dragon Sword, immediately locked on to Chu Xuan, and thunderbolts that were ten times more terrifying than before condensed and formed.

Even though Chu Xuan was mentally prepared, seeing such a scene, he couldn't help but feel his scalp go numb for a while.

There is no doubt that this is because he has intervened in the Heavenly Tribulation that does not belong to him. This is a warning from the Heavenly Tribulation to him.

If he still doesn't leave, the next step is no longer a warning, but a direct punishment!

But the arrival has already come, Chu Xuan naturally didn't want to give up halfway, he gritted his teeth, and immediately said silently in his heart: "System, sign in!"

Obviously, the system doesn't care whether it is a catastrophe or not, it acts completely according to the rules.

The moment Chu Xuan gave the order, its rules immediately began to operate.

At the same time, all the thunders rioted in an instant, as if they were completely enraged.

In the next second, those thunderbolts no longer cared about the Silver Dragon Sword, instead they all poured towards Chu Xuan like a violent storm.

Seeing this, Chu Xuan didn't dare to hesitate, and without saying a word, he mobilized the four magic weapons together, and instantly turned into four rainbows and roared forward together.

Accompanied by an earth-shattering roar, the whole world seemed to quiet down.

Only the newly born Qi Ling of Yinlongjian looked confused, looked up at the sky where the dark clouds had cleared: "Hey, where is my Heavenly Tribulation?"
