Among the four major families in the Diwei Empire, the Lu family is not the strongest, but it is not the weakest either.

The reason why Li Feng and Zhong Shuhui chose the Lu family was because the Lu family's headquarters was not in the imperial capital of the Diwei Empire.

There are many masters in the Diwei Empire. If there is too much movement, it will be difficult not to attract attention. Li Feng does not want someone to ruin his plan at a critical moment.

However, before going to the Lu family, Li Feng still had one thing to do.

That is, the evolved Hongmeng Holy Sword. For Li Feng, the Hongmeng Holy Sword is the most important weapon in his hand, but with the increase in strength, the power of the Hongmeng Holy Sword has become lower and lower. Therefore, as early as hundreds of years ago,

Before, Li Feng was already preparing to evolve Hongmeng Holy Sword

Already.

This time when he came to the Diwei Empire's imperial capital, Li Feng bought the final materials at the Treasure Pavilion of the Diwei Empire, so he prepared to evolve the Hongmeng Holy Sword before going to the Lu family.

Three days later, Li Feng came to a mountain range near the capital of the Diwei Empire.

The mountain range is called Qingtian Mountains.

It is a forbidden area in the Diwei Empire.

After entering the Qingtian Mountains, Li Feng quickly went deep into the Qingtian Mountains.

Half a month later, Li Feng arrived at the central area of ​​Qingtian Mountains.

"That's it."

Li Feng took out the Hongmeng Holy Sword.

There was also a hint of solemnity on his face.

It is not an easy task to evolve the Hongmeng Holy Sword.

"It must succeed."

Li Feng's consciousness moved, and various materials appeared in his sight.

Among these materials, the most important ones are gold and patchwork stone.

Yaojin and the Sky-Mending Stone have long been extinct in the prehistoric world. Even in Hongmeng World, it is not easy to find Yaojin and the Sky-Mending Stone.

Especially the Sky Mending Stone.

Even the colorful sky-repairing stones are of no use.

If you want to evolve the Hongmeng Holy Sword, you must use the Nine-Color Sky-Mending Stone.

Fortunately, I found the Nine-Color Sky-Building Stone in the endless void of the Ivy Immortal Realm before, but I didn't expect to use it this time.

After taking out the Yaojin and the Nine-Colored Sky-Building Stone, Li Feng split a part of the Nine-Colored Sky-Building Stone, and then separated the Yaojin.

Although the divided nine-color Sky-Mending Stone is not much, it is enough to evolve the Hongmeng Holy Sword.

Well, Li Feng didn't want to waste more, because he didn't know if he would be able to find the Nine-Color Sky-Mending Stone in the future.

Working together, Li Feng casts the Youzi Ye Fire.

Various materials were put into the Youziye fire for forging, and they suddenly made a crackling sound.

The Youziye Fire also kept trembling, and this Youziye Fire became more and more powerful. Li Feng used the magic technique to mobilize the Hongmeng Holy Sword to rotate, allowing the Youziye Fire to continuously temper the Hongmeng Holy Sword.

This refining process took three days. In three days, the Youziye Fire had turned the Hongmeng Holy Sword red.

The look on Li Feng's face also became brighter. He spent three days constantly consuming his true energy and physical strength. If he hadn't been strong enough, he would not have been able to hold on any longer.

Three days later, Li Feng saw the right opportunity, and with a flash of consciousness, Yao Jin flew towards the Hongmeng Holy Sword.

But Yao Jin stopped after he was five meters away from the Hongmeng Holy Sword.

At this time, the spell in Li Feng's hand was moving again, and the Youziye Fire became even more powerful.

At this moment, the mountain where Li Feng is located is like a sword pool, the world is like a sword pool, and the deep purple flames are constantly melting the gold.

A powerful energy wave spread.

The monsters, holy beasts and beasts all around were alarmed.

Gold is the hardest material in Hongmeng World. Adding gold to treasures can enhance the power and quality of the treasures, make the treasures stronger, and make the treasures sharper.

Now if the gold is to be integrated into the Hongmeng Holy Sword, it must be melted.

If you want to refine the gold, you must use special strange fire.

This Youziye Fire has been in Li Feng's hands for such a long time and has been continuously upgraded, and its power has reached a powerful level.

The refining of the gold took another three days. After three days, the gold was transformed into a golden solution.

Seeing this situation, Li Feng sacrificed the Nine-Colored Sky-Building Stone, and the Nine-Colored Sky-Building Stone entered the Youziye Fire.

The Nine-Color Sky-Mending Stone is a divine object used by the ancient powers to patch the sky. It is nine-color in color, has magical power, is powerful and shocking, and has a mysterious power that humans have not been able to figure out for countless billions of years.

However, this nine-color sky-repairing stone is definitely a magical material for refining treasures.

The Nine-Colored Sky-Building Stone entered the Youziye Fire, exuding a shocking aura. The breath continuously drove the Youziye Fire, and the flames of the Youziye Fire also continuously refined the Nine-Colored Sky-Building Stone.

Similarly, this nine-color sky-repairing stone is more difficult to fuse than gold.

It took Li Feng half a month to refine the Nine-Color Sky-Building Stone.

As the gold and the nine-color sky-repairing stone were refined, Li Feng's face showed excitement.

Then, Li Feng mobilized the Hongmeng Holy Sword, the Nine-Colored Heaven-Mending Stone, and the Golden Gold together.

boom!

Just when the Hongmeng Holy Sword and Yao Jin were fused together, a mysterious and powerful aura suddenly swept across.

This breath rose into the sky.

Tear apart space.

Even Li Feng was thrown out without any precautions.

The shocking aura soared into the sky, and the entire Qingtian Mountains trembled at this moment.

The aura released by Hongmeng Holy Sword is even more terrifying.

This Hongmeng Holy Sword itself is a heaven-defying existence. Its power and pressure can be said to be devastating to the heaven and earth. Moreover, it has been continuously tempered by Youziye Fire during this period of time, and its aura has gradually condensed.

It's just that the terrifying power has been suppressed and has not exploded.

The miraculous power of the Yaojin and the Nine-Color Sky-Mending Stone is no less impressive than the Hongmeng Holy Sword. Their power is astonishingly powerful. Either of the two materials can be called a peerless treasure. Now the two materials are fused together with other materials.

, the power of destruction finally broke out, and the Hongmeng Holy Sword suppressed the power that did not explode, finally at this time

At this time, the power of destruction finally broke out.

Hongmeng Holy Sword, Yao Gold, and Nine-Color Sky-Mending Stone.

Power tore through the void, and bursts of nine-colored light appeared between heaven and earth.

"puff."

Li Feng spurted out a mouthful of blood, with a look of horror on his face.

He never expected that the fusion of Yao Jin, Nine-Color Sky-Building Stone and Hongmeng Holy Sword would burst out with such shocking power.

Li Feng was actually prepared for this situation, and had plans and responses, but he never expected that it would be so powerful.

God is so powerful.

However, Li Feng was also very happy.

Because as long as the fusion can be successful, the evolved Hongmeng Holy Sword will become more powerful.

Rumble.

The sky is constantly torn in front of this power, and the Youziye Fire is constantly trembling.

"Click."

"Boom."

"Crackling."

At this moment, thunder appeared in the sky, and lightning fell down one after another.

Lightning split a crack in the space and directly bombarded the Qingtian Mountains. At the same time, the air in the sky continued to twist.

"What's going on?"

"What happened in the Qingtian Mountains?"

The Diwei Empire, and even countless strong men around the Diwei Empire, all focused on the Qingtian Mountains at this moment.

Each mysterious and ancient existence opened its eyes in the darkness of the netherworld.

"Is there any treasure?"

"It's been so many years, but I didn't expect there to be treasures in the Qingtian Mountains."

"It must be obtained."

One by one, these ancient beings walked out of the place where they had been secluded for countless years and headed towards the Qingtian Mountains.
