Outside, when the black thunder disappeared out of thin air...

At the same time.

A shocking roar sounded in the secret realm!

boom!

A terrifying black thunder suddenly flashed in the extremely thick dark clouds!

It was at this moment.

Secret realm, teleportation room...

Cheng Buzheng, who was sitting cross-legged on the cushion, withdrew his gaze that fell on the [Chaos Dao Tribulation Sword], turned to look up at the void ahead.

The golden light flowed in his eyes, looking extremely majestic.

It seemed as if his eyes could pass through many obstacles and see the sudden changes in the outside world.

Cheng Buzheng frowned slightly, but he quickly stretched out.

He murmured in his heart:

"What do you think of the way of heaven?"

"Even in the secret realm, it cannot be completely isolated. Is it a sign of the birth of spiritual treasures?"

In response to this incident!

Cheng Buzheng was both surprised and expected.

However, he also understood that the black thunder entrenched in the boundless dark clouds was the legendary [Spiritual Treasure Thunder Tribulation].

Only by surviving this tribulation can the [Chaos Dao Tribulation Sword] be completely promoted to a spiritual treasure.

Once this [Chaos Dao Tribulation Sword] cannot withstand the baptism of the thunder tribulation, the momentum of promotion will inevitably be interrupted, and naturally it will not be able to absorb the fortune from the black heavenly thunder, thus giving birth to the spiritual nature of the key core of the spiritual treasure.

same.

Cultivators cannot take action either. To reduce or resist the magic weapon in promotion, they must allow the magic weapon in the sublimation state to be completely baptized by the thunder tribulation.

Thoughts.

Many distracting thoughts flashed through Cheng Buzheng's heart, and at the same time, his eyes fell again on the [Chaos Dao Tribulation Sword] standing in front of him, connected by blood.

Although this treasure has been retrained, Cheng Buzheng understands it...

This does not mean that his years of sacrifice and refining have turned into useless achievements?

otherwise.

There will be no such blood connection in front of you.

But compared to before...

The connection between the [Chaos Dao Tribulation Sword] that respected the refining after refining is much worse than before!

same!

At this moment, Cheng Buzheng, who was sitting cross-legged on the cushion, clearly felt the extremely obvious changes in the difference.

"Oh..." Cheng Buzheng sighed lightly:

"It seems that we have to re-sacrifice!

One step further away from the state of ‘the unity of human and treasure’.”

Thinking of this.

Cheng Buzheng couldn't help but have a headache.

But he also understood that this was inevitable.

Unless the natal magic weapon will never be promoted.

However, when he thought of the [Innate Creation Bead], his mood was much better.

He didn't hesitate, and his mind moved...

A drop of golden spiritual blood emerged from his fingertips.

Then, the chaotic galaxy in Cheng Buzheng's sea of ​​consciousness differentiated into a chaotic starlight and penetrated into his body.

Finally, it was sank into the drop of golden spirit blood.

In an instant, the golden spiritual blood suddenly flashed.

Looking again, the drop of golden spiritual blood has turned into a colorful color, rippling with colorful and ten-color light waves, which is amazing.

good.

This drop of spiritual blood not only contains Cheng Buzheng's spirit.

It also covers his origin and foundation!

after all!

The chaotic starlight inside it merged with his original magic power, also included the origin of divine thoughts, and also covered the power of the Half-Step Lord's foundation power [Chaos Starry Sky] domain!

Then...

He flicked his fingers, and a colorful stream of light passed through the quiet room, sank into the [Chao Dao Tribulation Sword] floating in the sky.

Cheng Buzheng, who was sitting cross-legged on the cushion, made a series of seals and began to sacrifice and refine this [Chao Dao Tribulation Sword] without any hesitation.

He seemed to have not taken the black thunder that was constantly brewing power outside the teleportation room at all.

Actually, it is not the case!

Cheng Buzheng knew clearly that this was the heavenly thunder transformed by the [Spiritual Treasure Tribulation], which was in a brewing state and was about to be completed until the momentum was accumulated...

That was the time when the [Spiritual Treasure Tribulation] was truly opened.

Before, he took a look and realized that there was still some time before the [Spiritual Treasure Tribulation] was completely opened.

That's why.

Only then did Cheng Buzheng take advantage of the thunder tribulation that he had not started and sacrificed the [Chaos Dao Tribulation Sword].

after all.

The power of the magic weapon that is in promotion in the two states after the sacrifice and before the sacrifice is different is far from that of the magic weapon.

certainly.

Isn’t this Cheng Buzheng’s uneasy [Chaos Dao Tribulation Sword] unable to withstand the baptism of the thunder tribulation?

But he wanted to have more insurance.

At the same time!

The [Chaos Dao Tribulation Sword] floating in the sky was filled with hazy chaotic light, flashing constantly.

suddenly.

Cheng Buzheng, who was sitting cross-legged on the cushion, paused in his hands!

In an instant.

The [Chaos Dao Tribulation Sword], which was constantly flashing with a chaotic halo, suddenly shone brightly!

Then the [Chaos Dao Tribulation Sword] was slightly shocked!

Zheng!

The crisp sound of swords echoed in the teleportation room.

At the same time, a terrible aura rose up and struck the sky with a terrible aura!

At this moment.

Cheng Buzheng breathed a sigh of relief.

"Finally, before the arrival of [Spiritual Treasure Tribulation], the sacrifice and refining were successful!"

certainly.

This is not just that Cheng Buzheng completed the sacrifice and refining completely, but that he had a hurry to sacrifice and refine it.

after all.

Even ordinary magic weapons cannot complete the sacrifice and refining in such a short time.

Not to mention the spiritual treasure with a grade sequence above the magic weapon!

It's undoubtedly even more unrealistic!

Just then...

In the secret realm of the teleportation room, the unkempt dark clouds suddenly moved and gathered towards the center. The color became deeper and deeper, as if the black could drip out of ink.

Then, endless black clouds surged!

The center of the secret realm sky suddenly rotated, and a huge vortex appeared, and endless black clouds were swallowed up.
To be continued...
