Legendary Armament Canon

Zheng Jingyun thought about it. If this kid's cultivation was similar to his, coupled with his Laws of Time, then he, Zheng Jingyun, was probably really inferior to him!

At the thought of this, Zheng Jingyun felt uncomfortable all over.

Hmph, so what? This is the Sima Grotto-Heaven. I can also use the Laws of Time! I might be slightly inferior outside, but in the Sima Grotto-Heaven, I, Zheng Jingyun, will never lose!

Putting aside Zheng Jingyun's thoughts, Ji Lutian stared unblinkingly at Zhou Shu, who was enveloped by the white light.

He was actually a little nervous, which was rare for him. It had been many years since he felt so worried about gains and losses.

Previously, when Zhou Shu was forging the Compliant Golden-Hooped Rod, Ji Lutian was still in the mood to deduce what kind of connate divine weapon Zhou Shu wanted to forge based on the forging materials he used.

But now, he was in no mood to deduce.

Just seeing the forging materials that Zhou Shu took out gave Ji Lutian a headache.

The value of these forging materials had far exceeded Ji Lutian's estimates. It wasn't wrong to say that they were priceless.

With the massive amount of forging materials and the paragon bone, Ji Lutian didn't dare to say if Zhou Shu's divine weapon would be the number one weapon in the world if he could successfully forge it, but its cost was definitely the number one in the world!

Ji Lutian even saw Zhou Shu take out three Divine Stones at once!

Divine Stones were a necessary item for forging grotto-heaven divine weapons. In other words, Zhou Shu actually planned to forge a grotto-heaven divine weapon this time!

Connate divine weapons were also divided into good and bad ones.

Divine weapons that contained a world were completely different from divine weapons without a world.

This was like the difference between someone who had just broken through to the Grotto-Heaven realm and an expert at the peak of the Grotto-Heaven realm.

It seemed that there wasn't much of a difference, but in fact, there was a world of difference.

Generally speaking, grotto-heaven divine weapons were definitely stronger than ordinary connate divine weapons.

Ji Lutian was looking forward to seeing what kind of divine weapon Zhou Shu would forge.

Time sped up under the envelopment of the white light, and Zhou Shu's movements were so fast that they were almost invisible.

But this time, it wasn't like when he forged the Compliant Golden-Hooped Rod. Back then, the Compliant Golden-Hooped Rod had been forged in the blink of an eye.

Fifteen minutes had passed, but Zhou Shu was still moving.

Ji Lutian circulated his spiritual essence, and a light flickered in his eyes.

He was trying his best to see Zhou Shu's movements.

Zhou Shu's forehead was covered in beads of bean-sized sweat, and his face was extremely pale. He looked exhausted but determined.

Ji Lutian could tell that Zhou Shu seemed to be at the end of his rope and could collapse at any moment.

It was understandable. Controlling the Laws of Time was definitely not an easy task.

To be honest, Zhou Shu's ability to last fifteen minutes had far exceeded Ji Lutian's estimate.

Under the acceleration of time, Zhou Shu might have spent several years or even decades in these fifteen minutes.

Ji Lutian frowned and raised his voice. "Brother Zhou, let me help you!"

After seeing Zhou Shu nod, Ji Lutian raised his hands. The power in his body poured out and surged into Zhou Shu's body.

With Ji Lutian's support, Zhou Shu's expression improved slightly. But soon, he looked tired again.

"Zheng Jingyun!" Ji Lutian shouted. "Why are you looking at me like a fool? Help!"

Zheng Jingyun frowned. Although he was a little unhappy, this was the Zheng family's paragon bone after all. If the forging failed, it would also be a loss to the Zheng family!

"I'm not helping you. I'm doing this for the paragon bone!" Zheng Jingyun snorted.

He took a step forward and pushed forward with both hands, lending his strength to Zhou Shu.

With the help of two experts, Zhou Shu finally stabilized himself.

This was hard on Ji Lutian and Zheng Jingyun. The two of them felt the power in their bodies gushing out like a flood. In just a moment, the two of them felt as though they were about to be drained.

They looked at each other and saw the helplessness in each other's eyes.

What is Zhou Shu doing? Why is he using so much energy?

Even though they thought this way, the two of them didn't dare to relax at all. As they desperately circulated their cultivation techniques to recover their spiritual essence, they continuously sent all their energy to Zhou Shu.

The two of them seemed to have become two energy-converting machines, converting the spiritual qi of heaven and earth into spiritual essence that Zhou Shu could directly use. Throughout the entire process, the two of them were as tired as dogs without obtaining any benefits...

Time passed by bit by bit. Even with Ji Lutian's and Zheng Jingyun's cultivation, they began to shake. The two of them couldn't hold on any longer.

Zheng Jingyun was already considering looking for help. Zheng Chengan's cultivation was passable.

At this moment, the white light on Zhou Shu's body finally began to fade. At the same time, the weapon in his hand began to emit a dazzling golden light.

Ji Lutian and Zheng Jingyun seemed to hear a dragon's roar in their ears. The golden light was extremely dazzling and intense. Even with their cultivation, they couldn't see what the weapon in the golden light was.

Boom!

There was a sudden roar in the sky.

Ji Lutian's and Zheng Jingyun's expressions changed at the same time. They looked at each other again and saw the shock in each other's eyes.

Being in the Sima Grotto-Heaven, logically speaking, even though Zhou Shu had forged a connate divine weapon, it shouldn't have triggered a heavenly tribulation.

Grotto-heavens were independent small worlds isolated from the outside world. Only when one left the grotto-heaven would the connate divine weapon trigger a heavenly tribulation.

But now, the weapon Zhou Shu had forged actually triggered a heavenly tribulation through the grotto-heaven?
