Those blacksmiths left one by one, because their skills were all learned by Qin Yu. At the same time, one by one, the blacksmiths came to Yunwu Mountain Villa and continued to teach Qin Yu to strike iron.

Of course, every time I learn to strike iron, there are only two people, Qin Yu and the master of iron. Qin Yu understood that the blacksmith was very interested in his skills. So I don't want them to be embarrassed. Since they don't want more people to see their technology, be considerate of them and learn from them individually. Anyway, Qin Yu didn't suffer a loss.

For three months in a row, there were no less than 1,000 blacksmiths who had come to Cloud Mountain Villa. Qin Yu didn't dare to say that he had learned to strike iron with all the ironsmiths in the Qianlong Continent, but he dared to say that he had learned to strike iron with half of the ironsmiths in the Qianlong Continent. As for those who were not invited, they were either private blacksmiths or in the service of the royal family. Although Qin Yu didn't learn the iron-striking technique from all the iron-striking masters in the Qianlong Continent, it was enough for Qin Yu.

Next, he plans to remove the fake and retain the truth from the blacksmithing techniques he has learned, and then fuse them together to create a set of forging methods of his own.

However, for the time being, Qin Yu will not be able to achieve it. Because Qin De was about to cross the catastrophe, he had to personally escort Qin De.

…………

This time, Qin De was only accompanied by Qin Yu, Xiao Hei and Jin Yan.

Jin Yan is a demon cultivator in the early stage of the Yuan Infant; Xiao Hei is also already in the late stage of Jindan; Qin Yu is the Great Perfection of the Nebula Period, and it is possible to break through the Flowing Week at any time.

With the three of them escorting Qin De, it is naturally foolproof. Moreover, Wu Xing and Xiang Yang were all controlled by Qin Yu, and the news of Qin De's robbery was not leaked, so who else would disturb Qin De's robbery?

Qin Yu stepped on a high-grade flying sword and flew towards the flood wilderness with Qin De.

In fact, Qin Yu didn't need the Imperial Sword to fly at all. But in order to carry Qin De, he had no choice but to use the flying sword as a flying machine.

"Father, with the three of us guarding you, you can survive the tribulation with peace of mind when the time comes, and no one will be able to disturb you." Qin Yu said with a smile.

"I hope so." Qin De smiled indifferently.

"Father, you don't believe me." Qin Yu said helplessly.

"It's not that I don't believe you. Rather, you can't be careless. The Forty-Nine Heavenly Tribulation is a threshold for cultivating the truth, and it is naturally not so easy to pass. Back then, your grandfather died in the catastrophe. In short, it should not be taken lightly. Qin De said.

Qin Yu nodded. "Father, I understand."

At this time, Xiao Hei said, "Big brother, the flood has arrived, should we go down now or fly in again?" ”

"Let's go down. Anyway, it's the same everywhere. Qin Yu said. Although he understood Qin De's worries, Qin Yu was not worried at all, because he had extremely strong strength in the mortal realm and even in the outer wilderness. In the face of absolute strength, even if there is an accident, it will definitely not be able to turn over the big waves.

Qin De wanted to say something, but Qin Yu had already landed.

The place where Qin Yu and the others fell was a mountain peak on the edge of the flood wilderness. The peaks are not high, the mountains are not too steep, and they don't even have a name.

Qin Yu carved out a clearing at the top of the mountain, and then arranged it there.

"Father, the formation I am arranging now is called the Six Gates Golden Lock Formation, which ensures that you are foolproof under the Heavenly Tribulation. You can calm your heart and survive the catastrophe with peace of mind. Qin Yu said as he laid it out.

"Okay." Qin De said with a smile, he really didn't expect Qin Yu to set up a formation. However, Qin Yu's hand did make Qin De feel a lot more at ease.

After a while, Qin Yu arranged the formation. Qin De sat in the middle of the formation, quietly waiting for the Heavenly Tribulation to come.

"Xiao Hei, Xiao Jin, listen, when my father crosses the catastrophe, no matter who comes to disturb him, you will kill him with thunder. I don't want anyone or anything to disturb my father's tribulation. Do you understand? Qin Yu said solemnly.

"Understood, big brother." The two replied in unison.

Then Qin Yu, Xiao Hei, and Jin Yan formed a three-talent formation to protect Qin De inside. Waiting for the catastrophe that could come at any time, its own unexpected disturber.

Suddenly-

The wind swept through the sky, and the color of the sky above the mountain peaks gradually changed, turning a dark red.

"The Apocalypse is coming!" Qin De looked up at the dark red sky and said lightly.

Qin Yu also looked up at the sky.

I saw that the dark red sky began to spin, and purple electric snakes appeared from the dark red sky as if out of nothing, and then were sucked into the huge whirlpool. Gradually, the vortex stopped spinning and turned into a purple cloud.

"Boom!" There was a huge thunderclap, and an arm-thick purple thunderbolt slashed towards Qin De, who was sitting in the array.

In the face of the Heavenly Tribulation that had been slashed, Qin De did not panic, nor did he open the formation.

"Drink!" A low cheer sounded from Qin De's mouth, and at the same time, a golden dragon-shaped body protection qi appeared on Qin De's body, which was exactly the method of "Ancestral Dragon Jue" to cultivate to the innate extreme.

Qin Yu looked at the golden body protection qi on the surface of Qin De's body, his brows furrowed, the true qi cultivated by his ancestral dragon was black, but Qin De's ancestral dragon true qi was golden. It is also the cultivation of the Ancestral Dragon Duel, why is the color of the true qi different? Qin Yu couldn't figure it out.

However, Qin Yu also understood that now was not the time to ask, and it was not too late to ask when his father had survived the tribulation.

At this time, a dark red long sword appeared in Qin De's hand, which was a medium-grade spiritual weapon, and it was also Qin De's reliance on the tribulation.

Qin De raised the dark red long sword to resist, and at the same time, streams of innate true qi were imported into the dark red long sword. Purple lightning slashed at the sword, and the dark red sword trembled.

In an instant, the purple thunderbolt disappeared without a trace.

"Haha...... With this medium-grade spiritual weapon, it is really much easier to survive these forty-nine heavenly tribulations. Qin De began to be full of confidence at this moment.

The purple calamity clouds continued to roll, and the powerful coercion made everyone in the valley frightened, and the second heavenly thunder was obviously much more powerful.

Suddenly, the sky shook. "Boom!" Another purple thunderbolt slashed down from the sky at great speed, and compared with the first one, this thunder became thicker and thicker, and the purple light became more and more dazzling, and it had already been split down in an instant.

Qin De continued to raise his long sword to resist, with the experience of resisting the heavenly thunder for the first time, Qin De was much smoother this time. However, Qin De misestimated the strength of the second Heavenly Tribulation, and although the Second Heavenly Tribulation was finally blocked by Qin De, his face turned pale.

At this time, Qin Yu's voice came, "Father, hurry up and open the formation, the third heavenly tribulation is very powerful, and it can't be carried hard." ”

Qin De nodded, and finally opened the Six Gates Golden Lock Array. At the same time, Qin De took out Qin Yu and gave him the second-grade Qi Rejuvenation Pill to swallow. He can't rely on the formation for the success of the tribulation, he must recover as soon as possible to deal with possible crises.

The clouds in the sky rolled,

"Boom!" A purple dragon fell from above the Nine Heavens, carrying an oppressive coercion, and slashed directly at the Six Gates Golden Lock Array. However, today's Qin Yu is not the Qin Yu of the original Congenital Great Perfection. The six-gate golden lock array he arranged now was much stronger than the original positive and negative two ritual arrays.

I saw the purple heavenly thunder slamming on the formation shield, but it was never able to break through, and finally it could only slowly dissipate.

At this moment, Qin De was really surprised, he didn't expect the formation arranged by Qin Yu to be so powerful.

"Boom!" There was a terrifying thunderclap, and the last heavenly thunder was like a purple heavenly dragon rushing out of the clouds, slashing directly downward, and finally slashing on the shield of the Six Gates Golden Lock Array.

Although the fourth Heavenly Thunder was really powerful, the shield still didn't move at all, not even a trace of shock. Eventually, the power of the heavenly thunder slowly dissipated.

The four heavenly thunderbolts had passed, and the clouds in the sky slowly dissipated, and the dark red of the sky gradually receded, revealing the blue sky.

Qin De's tragedy was successful.
