Chapter 3701 The Jade Box Is Finally in Hand

"Do you think you can compete with me with external forces? The gap in strength cannot be made up by external forces! Let me show you what the absolute gap in strength is!"

The Seventh Sea Lord roared, accumulated the strength again, and rushed towards Gu Yuan, and the surging dark power burst out from the air.

Gu Yuan also picked up the silver needle and fought with the Seventh Sea Lord again.

"Go!"

Seeing Gu Yuan and the Seventh Sea Lord fighting in a group, Chu Fengmian also flashed and rushed directly to the depths of the valley. A compass suddenly emerged from Chu Fengmian's palm.

The direction pointed by the compass now is the depths of the valley. The jade box of the Lord of Sword Dao is indeed in the treasure house of the Nether Emperor.

Now that the Seventh Sea Lord is delayed by Gu Yuan, it also gives Chu Fengmian a great opportunity to find the jade box of the Lord of Sword Dao.

"How dare you, thief!"

In the sky, the Seventh Sea Lord who was fighting with Gu Yuan also noticed Chu Fengmian's figure. When he entered the depths of the valley, his face suddenly changed.

The treasures outside the valley were all ordinary things, not worth mentioning. Losing some of them was a loss. Anyway, the You Clan occupied the entire Nine You Sea, and a large number of treasures would be born all the time.

After waiting for a while, these lost treasures would reappear, but the treasures in the depths of the valley were different. The treasures there were all placed there by the You Emperor himself.

Except for the You Emperor, no one could touch the treasures there.

Even the second person in the You Clan, the Seventh Sea Lord who was responsible for guarding the You Emperor's treasure house, was also not qualified. Even the most important treasure of the You Emperor, the You Sea Core Fragment, was placed there and must not be lost.

The Seventh Sea Lord was furious and wanted to chase Chu Fengmian, but he was stopped by a figure in front of him.

"Your opponent is me!"

Gu Yuan smiled, holding a silver needle, and attacked the Seventh Sea Lord again. In front of the burst of the power of nothingness, the Seventh Sea Lord had no time to split himself and could only deal with it with all his strength.

On the other side, Chu Fengmian had really entered the depths of the valley. The depths of the valley were an independent small world, which was completely different from what the outside world saw and was extremely huge.

Treasures were suspended in this small world. These treasures were large and small. The first thing Chu Fengmian saw was a crystal fragment as big as a planet.

It showed a slightly transparent black color. On this planet-sized crystal fragment, Chu Fengmian felt an extremely pure dark force.

The core fragment of the Youhai!

The most powerful Youhai core fragment that Chu Fengmian felt from the outside world was the planet-sized crystal fragment in front of him.

In addition, there are thirteen other Youhai core fragments of different sizes, but the smallest one is as big as a mountain.

A total of fourteen Youhai core fragments are Gu Yuan's goal this time. The power contained in them is the power of the entire Nine Youhai core.

Whoever can get all of these fourteen Youhai core fragments can fully master the power of the Nine Youhai.

Of course, this is extremely difficult. Even the Emperor of Youhai spent a lot of effort to master the core of Youhai, and finally broke the core of Youhai. Even the ninth-level Immortal Emperor can hardly get all the Youhai core fragments.

But as long as you get a Youhai core fragment, the huge power contained in it is enough to forge an extreme immortal weapon, integrate it into yourself, and even transform your own strength. It is not surprising to go further and impact the level of the ninth-level Immortal Emperor in one fell swoop.

This is Gu Yuan's purpose. Gu Yuan's true realm should have reached the peak of the eighth-level Immortal Emperor. The purpose of his desire to obtain the Youhai core fragments is to use the Youhai core fragments to impact the level of the ninth-level Immortal Emperor.

For this reason, Gu Yuan did not hesitate to take out the silver needle of the Void God, which is his strongest trump card.

In addition to these Youhai core fragments, there are some strange treasures in this small world deep in the valley, including extreme immortal weapons, some immortal pills, wonders of the heavens, epoch treasures, and even many things that Chu Fengmian could not recognize their names.

He could only feel an incomparably huge power from these treasures.

Chu Fengmian's eyes now just swept over them, without stopping at these treasures at all. Even those Youhai core fragments, Chu Fengmian did not collect them at the first time. His eyes were always fixed on the direction indicated by the compass and flew over.

At the edge of this small world, according to the direction indicated by the compass, Chu Fengmian finally found a jade box. This jade box was made of a material that had never been seen before.

On this jade box, an extreme sword seal was clearly visible. The power of this extreme sword seal was the power of the Lord of Sword Dao.

Only the disciples of the Sword Dao Sect and the disciples of the Lord of Sword Dao could understand the method of resolving this extreme sword seal, so this jade box, even if it was obtained by the Emperor of the Underworld, has never been opened.

On the jade box, Chu Fengmian found some remnants of dark power. It seems that the Emperor You had tried several times to open the jade box, but failed in the end.

Before Chu Fengmian had time to observe carefully, he felt the aftermath of the power that exploded outside. It seems that the ancient origin can't delay the Seventh Sea Lord for long.

The power of the silver needle is almost enough to kill an eighth-level immortal emperor instantly, but for a ninth-level immortal emperor, it can only delay time.

If the silver needle is powerful enough, a ninth-level immortal emperor can only barely fight it, but the silver needle is still an external object after all, and the power of nothingness in it is limited.

Once the power of nothingness in it dissipates, the ancient origin can no longer delay the Seventh Sea Lord, and Chu Fengmian has little time left.

Chu Fengmian reached out and grabbed the jade box of the Lord of Sword Dao. The power of the jade box was powerless against Chu Fengmian, and it fell directly into Chu Fengmian's hands and was put into the empty ring by Chu Fengmian.

His purpose of coming to the Nine Netherworld this time was finally accomplished.

Seeing the jade box fall into the empty ring, Chu Fengmian finally smiled. However, since he had spent so much effort to come to the Netherworld Treasure House this time, Chu Fengmian wanted to get more than just the jade box of the Lord of Sword Dao.
