Nine Domain Sword Emperor

The dark stone in the hands of Cangsheng Tianzun, Prince Xi and Princess Fuhua also fell into the hands of Chu Fengmian.

The dark stone in the hands of the three of them is the same as the dark stone in Chu Fengmian's hand. It exudes this unique power and can be used to resist the power of the forbidden formation in the Nine Nether Sea.

Only warriors holding dark stones can enter the Nine Nether Sea.

The power of the dark stone is limited. Once the power of the dark stone is exhausted, the warrior must leave the Nine Nether Sea as soon as possible before the power of the dark stone is exhausted.

Otherwise, there is a risk of falling into the Nine Nether Sea.

How long the power in the dark stone can last also means how long the warrior can stay in the Nine Nether Sea.

For example, in this Netherworld War, the warriors ranked sixth to twentieth were also qualified to enter the Nine Netherworld Sea.

It's just that unlike Chu Fengmian's rewards for the top five in this Netherworld War, the Dark Stones obtained by these warriors can only enter the outer sea of ​​the Nine Nether Sea, and are not eligible to enter the inner sea. Moreover, the Dark Stone lasts for only Three days.

This means that they can only stay at sea for three days at most.

The dark stone that Chu Fengmian obtained contained power that could last for seven days, which meant that Chu Fengmian could stay in the Nine Nether Sea for seven days.

However, the Dark Stone itself has no owner, so no matter who gets the Dark Stone, they can enter the Nine Nether Sea.

For these warriors who have entered the Sea of ​​Nine Netherworlds, if they want to stay in the Sea of ​​Nine Netherworlds for a longer period of time, what they have to do is to get more dark stones.

As long as there are more dark stones, you can stay in the Nine Nether Sea for a longer time.

This is also the reason why Prince Xi and Princess Fuhua are eyeing Chu Fengmian.

Their real purpose is to seize the dark stone in Chu Fengmian's hand.

In fact, not only Chu Fengmian, but also the Ancient World Honored One and the Celestial Being were also targeted by them. However, compared to these two people, Chu Fengmian had the weakest strength background, so they finally chose Chu Fengmian.

But now, not only did these two people fail, Chu Fengmian also obtained the dark stones in their hands. These three dark stones probably took about a day.

The three dark stones have now been sealed by Chu Fengmian, and they are ready to wait until the power of the dark stone in Chu Fengmian's hand is exhausted before using it. The combined power of these three dark stones should be able to maintain eighteen more than days.

Obtaining these three dark stones means that Chu Fengmian can stay in the Nine Nether Sea for eighteen more days. This is Chu Fengmian's biggest gain from this battle.

With these extra eighteen days, Chu Fengmian doesn't need to be so anxious and can explore the Nine Nether Sea.

This Nine Nether Sea comes from the extremely ancient Abyss Era, and there are countless treasures and opportunities in it.

For example, the places where some treasures are located have been marked out by others, and they only need someone to go and get them. The Prince of Xi Kingdom and Princess Fuhua joined forces this time because the Prince of Xi Kingdom obtained a treasure map and confirmed it. In this Nine Nether Sea, there is an ancient secret.

It was just that the ancient secret treasure was guarded by a force that the Prince of Xi Kingdom could not obtain. So he chose to invite Princess Fuhua to join forces, preparing to open the secret treasure and divide the treasures among them.

But now, all this is in vain, this treasure map has also fallen into the hands of Chu Fengmian.

"Is the location marked by this secret treasure actually in the restricted area?"

Chu Fengmian glanced at the location recorded in the treasure map and frowned.

The location of this secret is not in the inner sea or the outer sea.

And leaving these two sea areas, other sea areas in the Nine Nether Sea are called restricted areas.

Of course, warriors are not allowed to enter this restricted area in name only, but more importantly, it is because it contains dangers.

The inner and outer seas of the Nine Nether Sea are controlled by the four major inheritance forces, so there is no threat in them, and some dangerous existences have been driven out long ago.

But leaving the inner sea and the outer sea, the vast sea outside is a restricted area for warriors, and there are even powerful creatures born in the Nine Nether Sea.

Generally, very few warriors who enter the restricted area can come out alive.

This time, Prince Xi and Princess Fuhua seemed to be planning to directly enter the restricted area to find the secret treasure.

Before that, the two of them planned to seize a dark stone to provide additional protection and extend their stay in the Sea of ​​Nine Netherworlds, so they set their sights on Chu Fengmian.

But neither of them could have imagined that they would be suppressed by Chu Fengmian in the end, and that the dark stone and the treasure map would fall into Chu Fengmian's hands.

According to the words of Prince Xi, the secret treasure recorded in this treasure map is most likely a secret treasure left by a powerful ninth-level Immortal Emperor.

That's why he took such great risks and wanted to enter the restricted area to find the secret treasure.

"The secret treasure left by the Nine Tribulations Immortal Emperor"

Chu Fengmian's eyes narrowed.

This is also very tempting to Chu Fengmian.

The level of the ninth-level Immortal Emperor is now also an intangible level for Chu Fengmian.

His strength is considered a strong one among the eighth-level Immortal Emperors, but he is still far away from the ninth-level Immortal Emperor.

Most of the eighth-level Immortal Emperors have spent their entire lives unable to take a step further to reach the Nine Tribulations Immortal Emperor, the pinnacle of the Immortal Emperor.

The higher the level of Immortal Emperor, the more difficult it will be to advance to the first level.

Even Chu Fengmian could feel that it was becoming more and more difficult for him to comprehend the laws.

As more laws are comprehended, the difficulty of comprehending other laws will also increase. Chu Fengmian has not yet truly mastered the seventh law.

If it weren't for Chu Fengmian's blessing from the seven innate divine beasts, the Blood-Slaying Demon Sword, the Jianmu Sacred Tree, ancient swordsmanship books, and countless opportunities, he wouldn't be as strong as he is now.

If we can get the secret treasure left by a ninth-level immortal emperor, it will be of great help to Chu Fengmian in the future to attack the realm of the ninth-level immortal emperor.

However, this is a rumor after all. Chu Fengmian cannot guarantee whether the secret treasure recorded in this treasure map was left by a ninth-level immortal emperor.

In comparison, it is more important to find the jade box left by the master of swordsmanship. However, both of them are in the restricted area. Maybe they can be found along the way.
