Lu Tianyu had no idea about the Venerable Master's exit from the Spiritual Tribulation, and he was still staying in the Zhao family at the moment.

This is an underground cultivation secret room, this secret room was originally used by Zhao Yunbing for cultivation, but now, it was given to Lu Tianyu.

"Huh!" opened his eyes, Lu Tianyu's eyes quickly flashed two dazzling essences, through this period of cultivation, his spirit and spirit finally returned to their peak state.

With his right hand, he patted the storage bag on his waist, and immediately, a small gray cloth bag appeared in his hand.

This thing, extraordinary, is the Qiankun bag snatched from Zhao Dayu.

This Qiankun bag is also a treasure borrowed by Zhao Dayu from the ancient Taoist faction, and he wanted to rely on this thing to successfully sit on the throne of the head of the family, but who knows, but with the appearance of Lu Tianyu, things came to a shocking reversal, not only failed in the election, but also made this treasure fall into the hands of Lu Tianyu.

Not long ago, Zhao Dayu came once and wanted to find Lu Tianyu to return to the Qiankun bag, but Lu Tianyu ruthlessly refused.

In the election of the head of the Zhao family, he did not prohibit snatching other people's magic weapons.

In addition, Lu Tianyu almost died in this Qiankun bag, if he hadn't taken precautions in advance and laid out the secret chess of the big demon, I'm afraid that he would be proud of him Zhao Dayu now.

To sum up, Lu Tianyu would not give up such an anti-heaven magic weapon, because this Qiankun bag would still be of great use to him.

"Snort" Lu Tianyu's index finger was a little, and a drop of blood quickly flew out and sprinkled it on the Qiankun bag.

"Whew!" After absorbing Lu Tianyu's blood, Qiankun Bag instantly turned red, and a dazzling red glow suddenly penetrated into his eyebrows.

Confess the Lord with a drop of blood, over.

Suddenly, like a thunderbolt, Lu Tianyu suddenly had countless strange information in the sea of consciousness, and this information was all about Qiankun bag.

After a little tidying up, Lu Tianyu immediately knew that this Qiankun bag was a low-grade space artifact, although it was of the same grade as the prison god cage, but it belonged to the best of the lower grades, and it was only one step away from entering the middle-grade artifact level.

This treasure, if it is arranged in advance, can trap the super strong in the early realm of the War Emperor, even if it is a strong person in the middle realm of the War Emperor, it can be trapped for a few hours, and only by cultivating to reach the terrifying late realm of the War Emperor can it be forcibly broken and get out of the trap.

Knowing the relevant information of the Qiankun bag, Lu Tianyu couldn't help frowning slightly.

Although this treasure is against the sky, it has a fatal flaw, that is, it must be arranged in advance, and it cannot be taken out at will like the cage of the god to trap the enemy.

Lu Tianyu was extremely dissatisfied with this, after all, when facing the enemy in the future, if you are at a critical moment of life and death, the enemy will never give you time to let you slowly set up the trap.

"We have to think of a way to change this defect of the Qiankun bag, so that we can achieve a surprising victory against the enemy in the future!" Lu Tianyu couldn't help muttering, his brows were deeply locked, and he quickly began to think, wanting to find a way to improve it.

Time passed quietly, and the thoughts in Lu Tianyu's mind turned back and forth, and half an hour passed in a blink of an eye.

"Huh!" At this moment, Lu Tianyu's frowning brows finally relaxed, and a flash of ecstasy quickly flashed on his face.

"Now, I already have two space artifacts, one is this Qiankun bag, and the other is the prison god cage, but the grade is not high, only the lower grade artifact level, if you can use the fusion weapon method in the "Pangu Heavenly Book" to perfectly integrate these two artifacts, wouldn't it be able to make up for their respective defects and deficiencies?"

In the "Pangu Heavenly Book", there are not only many refining methods, but also the method of integrating two artifacts with the same nature, commonly known as fusion.

Compared with refining one's own artifact, this method of integrating existing artifacts into one is obviously much easier.

It's just that Lu Tianyu has never refined a weapon in the past, nor has he fused any artifact, this is the first time he has done it, and he is inevitably a little apprehensive in his heart.

If the fusion is successful, then the two artifacts can become one artifact, which will not only improve in grade, but also complement each other's advantages and disadvantages to achieve a perfect fit.

However, if the fusion fails, it means that both artifacts will have to be scrapped.

"In order to obtain a real anti-heaven magic weapon, fight!" Lu Tianyu thought for a moment and quickly made up his mind.

Today's prison cage can only trap the strong in the War Queen period, and it has little effect on Lu Tianyu, and this Qiankun bag, although it can trap the strong in the early stage of the War Emperor, must be arranged in advance.

Instead of holding these two flawed artifacts, it is better to try the fusion weapon, if it really fails, it can only mean that you are not blessed to have such a magic weapon against the sky.

As the saying goes, wealth and danger are sought, and Lu Tianyu's character has never lacked this kind of adventure factor.

After carefully recalling the fusion method in the Pangu Heavenly Book in his mind, Lu Tianyu immediately took a deep breath, calming his mind.

"Huh!" Under the frantic operation of the Inner Dan, the battle qi in the body instantly surged out, pouring into the hundreds of millions of meridians in the body, and began to run rapidly according to the route of the melting device.

After about five minutes, the battle qi finally ran for a week.

"Whew!" Lu Tianyu waved his right hand, and saw a dazzling red flame emerge from the palm of his hand, twisting and changing, and suddenly turned into a huge crimson furnace, levitating in front of him.

As soon as the Ding furnace took shape, there was a scorching high temperature, which spread out in an instant, and the entire floor of the secret room and the surrounding walls immediately emitted a crisp sound, but under the protection of the battle qi defense cover that Lu Tianyu had arranged before, it was safe and sound, and it was not only burned out of the pit.

"Boom!" With a movement of divine thoughts, the Qiankun bag and the prison cage all burrowed into the crimson Ding furnace.

"Refine!" Lu Tianyu's eyes shot out, his right hand waved again and again, and in his palm, countless dazzling red sparks suddenly shot out, and he frantically drilled into the crimson furnace.

These sparks, like tinder, under the amplification of the Crimson Ding Furnace, immediately burned wildly, and countless flame dragons roared in the Ding Furnace.

Soon, the Qiankun Bag and the Prison God Cage, under the continuous incineration of these flame dragons, began to emit bursts of crisp sounds, and at the same time, wisps of black smoke that were recognizable to the naked eye overflowed from the surface of the two artifacts.

Because these two artifacts are finished products that have been refined, there are not many impurities in them, and in less than a quarter of an hour, no more impurities and black mist emerge from the two artifacts.

The first step, refining the impurities, is completed.

The second step, which is very simple, is to refine all these two artifacts into a liquid state.

Although this step is simple, it is very energy-intensive, because the higher the grade of the artifact, the more difficult it is to refine it into liquid.

Lu Tianyu's right hand waved again and again, and countless crimson sparks poured out and drilled into the Ding Furnace.

These sparks instantly turned into prairie fires, and began to burn frantically against the two artifacts, with bursts of crackling and crisp sounds, quickly resounding throughout the secret room.

Soon, the cage began to soften, slowly transforming from a solid state to a liquid state.

However, the high-grade Qiankun bag is like a rock, indestructible, no matter how the flames burn, the vultures maintain a solid shape.

"I don't believe it, I can't help you with this low-grade artifact!" Seeing this, Lu Tianyu's eyes suddenly flashed with a ray of madness, and he desperately urged the battle qi in his body, and began to continuously inject sparks into the Ding Furnace.

"Huhu!" With the addition of Mars, it instantly turned into countless violent flame dragons, roaring wildly in the Ding Furnace.

The speed of the prison cage melted faster, and at this moment, even the rock-solid Qiankun bag began to slowly soften.

Time flickered, and an hour passed in the blink of an eye.

At this time, the prison cage had already turned into a mass of golden liquid, suspended at the edge of the inner edge of the Ding Furnace, only the Qiankun bag, and a small part of it had not melted, and it was in a solid form.

And with the consumption of battle qi energy, Lu Tianyu at this moment was already exhausted, his face was as white as paper, and there were countless bean-sized drops of sweat on his forehead, rolling down.

Lu Tianyu's eyes burst out with two rays of unyielding light, and with a sudden wave of his right hand again, he transformed the little battle qi left in his body into a crimson spark and injected it into the Ding Furnace.

"Zizi!" These flames turned into sparks, all under the control of Lu Tianyu's divine thoughts, converged to the solid position of the Qiankun bag, and with a piercing crisp sound, the palm-sized solid position immediately began to soften rapidly at a speed that was recognizable to the naked eye.

Finally, after a quarter of an hour, the artifact Qiankun bag had become like a prison cage, turning into a ball of golden liquid, suspended in the middle of the Ding Furnace.

Lu Tianyu's body shook violently and almost fell to the ground, but looking at the two liquids in the Ding Furnace, in those gloomy eyes, he couldn't help but quickly flash two rays of happiness.

Next, the crucial third step is to make the two liquids merge.

This step is similar to the process of refining the right arm of the demon god in the past and merging it with his own arm.

After cultivating for nearly half an hour, after all the battle qi in his body had recovered, Lu Tianyu immediately started the third step without hesitation, Melting Weapon.

With a movement of the divine thought, it quickly turned into thousands of threads, burrowed into the Ding Furnace, and covered the two masses of liquid.

Slowly, these two blobs of golden liquid began to gradually fuse according to Lu Tianyu's wishes.

The sound of "Ziz" was incessant, resounding throughout the secret room.

Time flies, and in the blink of an eye, a day and a night pass.

"Haha!" Just as the eastern sky was just revealing the whiteness of the fish's belly, a shocking laugh suddenly came from the secret room.

I saw that in front of Lu Tianyu, there was already a huge golden Ding furnace, on this Ding furnace, it was vaguely recognizable, and there were two strange patterns carved on it.

These two patterns, the left is the Qiankun bag, and the right is the prisoner cage, one left and one right, perfectly covering the surface of the Ding furnace.

"In the future, I'll call you Qiankun Ding!"

Lu Tianyu turned his right hand into a knife, and quickly carved the words "Qiankun Ding!" on the Ding furnace.
