Hearing this, Luo Zheng couldn't help but nodded, stopped what he was doing, a thoughtful look appeared on his face, and after a while, he nodded and shook his head.

"What's wrong?" Yu Jing looked strange and asked.

"Miss Yujing is right. A strong body is the fundamental way. A strong body is more important than practicing the art of refining weapons. However, this varies from person to person. Like our human race, our natural body is far inferior to that of monsters.

The beast is so powerful that it is far inferior to even the ferocious beasts without intelligence. If we give up on refining weapons, we are probably not far from destruction."

"So, I think that there are thousands of avenues, and all are possible. As long as you choose the right path, there is no such thing as which one is more powerful."

Luo Zheng showed his white teeth and smiled brightly.

"Maybe you are right." Yu Jing pondered.

An hour later, Luo Zheng finally collected all the things in the cave, filling six gourds of heaven and earth.

"Tsk, tsk, it seems that no matter how powerful you are in refining weapons, it's not as fast as robbing a family. If you find a few more transformed monsters like the big black bull, I won't have to worry about it in the future. Although many of those materials are up to

It is not at the level of condensing the Eighty-one Heavenly Swords, but it can be sold for money. If you spend more time refining them into magic weapons, you will make even more money."

Luo Zheng's pocket has never been so bulging as it is now, and he is in a very happy mood. He is thinking about talking to Yu Jing about finding a few more demon kings to fight against the autumn wind in this mountain of thousands of demons.

If it weren't for Yu Jing's support and even if he had a hundred more courage, he wouldn't dare to enter the Ten Thousand Demons Mountain Range, let alone say that he wanted to rob the Demon King.

The demon kings are all transformed demon beasts. Any one of them is stronger than Elder Xifeng. He can kill Luo Zheng with just one finger.

Thinking about it in their minds, the two of them arrived at the bottom floor of the cave. A huge stone door, weighing at least tens of millions of kilograms, completely sealed the bottom floor.

"It seems that the benefits here are not trivial. With the IQ of the big black bull, he actually knows to seal the entrance."

Luo Zheng was a little surprised. He didn't expect Da Hei Niu to know how to set up defenses.

"This shameless stupid cow, no matter how tight you seal it, it's useless."

Yujing said coldly.

The giant golden claws struck out, and the huge stone door shattered into pieces, and a hot air rushed towards the face.

With Luo Zheng's cultivation level, his skin would feel hot when he was hit by the hot air. When the hot air penetrated into the wounds on his body, it would be extremely painful. He quickly circulated his true energy to protect his body.

Looking inside the stone door, one can see the fire inside and the hot air rolling into the sky. In front of it is a huge stone platform suspended in the air, and underneath it is running and rolling, turning out to be an underground magma river.

"It's strange. There's no treasure here. Why is the big black cow so mysterious?"

Luo Zheng walked in and looked around, but he didn't find anything valuable. He couldn't help but feel surprised.

"Hey, what is this, a door panel?"

Luo Zheng discovered that there was a high iron platform on the stone platform. On it was a rotten iron block that was larger than the door panel. The iron block was also connected to a long handle as thick as a tree pole.

The iron door panel and the long handle were pitted with holes, and one side had a cutting edge, which looked a bit like a huge long-handled sword.

"Isn't this the big black cow's treasure? How stupid!"

Luo Zheng was stunned for a moment, looking at the door panel, he couldn't help but burst into laughter, he was angry and funny at the same time.

This rotten iron door broadsword was actually smelted and cast from an unknown number of precious materials. The materials were mixed together in a mess regardless of category or attribute, leaving Luo Zheng speechless.

"Young Master, it seems that that big stupid cow is in the same league as you, and is a master of weapon refining."

Yu Jing looked at the broken door panel and the sword, chuckled and said teasingly.

"What Miss Yujing means is that I am as stupid as a big stupid cow."

Luo Zheng held his forehead.

That big stupid cow doesn't even know what the art of refining is. He just throws the materials into the magma river to melt them without even a fire source, and then mixes them together randomly. Is this called refining?

"Okay, you can refine that drop of blood essence here. I will help you. It will probably take only one month to completely refine it."

Yu Jing said.

Luo Zheng thought for a while and said: "Miss Yujing, I will try it myself first to see if I can refine it. If not, how about you help me?"

Although the energy contained in this drop of essence and blood is extremely powerful, Luo Zheng is still confident enough to refine it with the help of the Heaven-Bearing Sword Formation.

"Okay, I'll help you protect the law."

Yu Jing showed surprise and looked at Luo Zheng. Seeing that he always had a confident expression on his face, he said no more and went to the corner of the stone platform to sit cross-legged and breathe.

As she vomited and inhaled, the lava river below rolled up masses of hot air that condensed into substance and was inhaled into her body.
