After entering the Mountains and Rivers Diagram, Chu Yunfan first smelled a strange fragrance, and almost instantly, he could feel that his mind was clear for a while, and he began to get twice the result with half the effort when thinking about problems, and the efficiency of brain operation was doubled.

It was he who ignited the usual Narwhalal Whale Oil, and the fragrance emanating from the Narwhalal Oil made him feel that his mind was quick, and the efficiency of his brain was doubled.

This also means that Chu Yunfan's cultivation speed may be twice as fast as originally expected, what an astonishing speed.

Originally, Chu Yunfan's cultivation speed was already unimaginable to ordinary people, and he grew up like a rocket, but under the increase of this unicorn whale oil, it could be doubled.

This speed is no longer imaginable for ordinary people.

At this time, he suddenly understood why in ancient times, many emperors preached at the age of tens, and hundred-year-old preachers abounded, and their talents were far beyond ordinary people, which can be described as talented, plus all kinds of good things piled up, plus in ancient times, all kinds of trials were more cruel than now, all of which urged these emperors of ancient times to grow up at the fastest speed.

Chu Yunfan sat down, and in front of him, an unformed sword appeared in front of him, this unformed sword looked quite wide, there was a person about the wide, the whole body was dark, it didn't look like a sword, but a ruler, a huge black ruler.

But there was an amazing sword intent on this sword, and this sword intent seemed to be sealed in the sword body and could not break through, but Chu Yunfan could intuitively feel that this amazing sword intent seemed to be able to break through the sky.

"It is rumored that the Covering Sea True Monarch swept the East China Sea with one hand and had almost no opponents, now it seems that the rumors are true, this sword intent is just a trace of seeping out, it is already very amazing, and if you are not careful, you can hit a master of the Creation Realm hard!" Chu Yunfan's expression was extremely solemn, and he infiltrated his divine thoughts into this black sword.

It was only a matter of moments, and he had already retreated with a pale face, and the divine thoughts he had infiltrated into were actually strangled by the sword intent contained in it.

"What a fierce sword!"

Chu Yunfan could feel the endless ferocious aura that permeated it, and this sword could be called a fierce sword.

And it's not at all what Chu Yunfan thought, it's an unfinished sword, on the contrary, this sword has actually been completed, and this sword is finished.

As the saying goes, the heavy sword has no edge and is not skillful, which is to describe this sword!

And Chu Yunfan finally learned the name of this sword, covering the sea!

The true monarch of the sea gave this sword with his own name, and once swept through the sword I don't know how many strong enemies.

And now that it has fallen into the hands of Chu Yunfan, the current Chu Yunfan has no way to completely control the Sea Covering Sword, there are a total of three layers of sealing enchantments in the Sea Covering Sword, and every time one layer is unlocked, the power of the Sea Covering Sword will be drastically improved.

And at present, Chu Yunfan has only only reached the minimum level requirements for using the Sea Covering Sword.

Thinking of this, Chu Yunfan immediately no longer hesitated, and directly cast the magic trick on refining weapons in the Emperor's Extreme Battle Canon, and began to refine the Sea Covering Sword.

When the time comes, with the Sea Covering Sword to defend himself, Chu Yunfan's own combat power will also have a huge increase.

Three days passed in the blink of an eye, and just when Chu Yunfan was going all out to practice the Sea Covering Sword, above the East China Sea, the conflict between the army of the prince of the Great Xia Dynasty and the army of the sea prince of the Sea Clan finally came to an end.

After three full days of bloody fighting, both sides suffered heavy losses, and the battle losses have exceeded fifty percent, such battle losses can also be called heavy losses on the battlefield, and they have not collapsed until now, which shows what elite troops both sides are.

Both sides were holding their breath and wanted to take revenge back, and all kinds of terrible weapons of mass killing were thrown at each other's bodies.

It's just that the strength of the two sides is almost the same, and no side can completely occupy the advantage, even if the Sea Clan side occupies the geographical advantage, but the other forces in the Sea Clan have no intention of intervening, just watching.

Obviously, there are not a few people who sit back and watch both sides lose, and even many people in the Sea Clan have the same idea.

In the course of three days, the two sides continued to have more troops and more masters joining the battlefield like a refueling tactic, and the entire sea area had been stained red with blood, and it was no longer like sea water, but a pool of plasma.

I don't know how many masters of both sides have fallen, there are human races, there are sea tribes, and more are deep-sea beasts with low intelligence, but they are huge and have extremely powerful strength.

The blood flowed, and these countless deaths and injuries scared even those deep-sea beasts that were not under the control of the Sea Clan.

Ordinary fights in the East China Sea will attract the pursuit of these fierce beasts in the sea, and now those murderers in the sea have just approached the battlefield, they have been scared half to death, and the powerful murderous aura that erupts from both sides is not at all something that ordinary deep-sea beasts can withstand.

The battle lasted until the third day, when the allied forces of the Li family and the prince finally began to withdraw from the battlefield first.

Although they were severely injured and almost disabled, the elite troops of the Li family still withdrew from the battlefield in an orderly manner, but the retreat speed was extremely fast, and they did not even try to take away the bodies of their comrades who fell into the sea.

And the Hai Clan's side also suffered heavy losses, and the loss was not under the alliance of the Li family and the prince's family, and it was naturally a big loss to do it with the strength of one family.

I used to hold my breath to avenge the Sea Prince, but now this breath is long gone, and the loss is so great that the high-level Sea Clan leaders of the Sea Prince's family want to cry without tears.

The losses of those deep-sea beasts they controlled were already countless, not to mention that although the masters of the Sea Clan had been hiding behind and letting the deep-sea beasts charge, they were still the key targets of the Li family's fleet.

The losses of the masters of the Qiankun Realm are even more numerous, and the first battle directly cripples this army.

At this point, they were powerless to pursue, and they even wished that the Li family's army would leave quickly, otherwise, it would be difficult for them to say who would collapse first.

Soon, the reason why the Li family withdrew from the army also came out, that is, the Hun Tianhou of the Great Xia Dynasty, who had disappeared, and Li Qianyuan actually reappeared.
