Chapter 4490: Breakthrough to the Sixth Floor

In this empty ring, there are more than a thousand blood jades produced by Xueyuan in this month, lying quietly in the empty ring.

Chu Fengmian's mind moved, and all the blood jades flew out.

At the same time, the Key of Time also emerged, and countless blood jades burned again.

This blood sacrifice ceremony for immortal soldiers is already very familiar to Chu Fengmian.

Soon the blood jade was completely burned out, and the power in it was all integrated into the Key of Time.

Seeing that the power of the Key of Time was sufficient, Chu Fengmian did not hesitate to activate the power of the Key of Time again. A force of time burst out from the Key of Time and turned into the Gate of Time again.

This is not the first time that Chu Fengmian has opened the door to the Primordial Land.

With the experience of the last time, Chu Fengmian's speed this time has become much faster. He has already determined the coordinates of the Primordial Land in the long river of time.

So this time, Chu Fengmian does not need to look for the coordinates of the Primordial Land specifically, but can directly open the door to the Primordial Land, which saves a lot of time.

Using the Key of Time to open the River of Time requires a lot of power every moment. Saving a little time means that Chu Fengmian can open the gate of the Primordial Land for a longer time to get more Primordial Power.

The gate of the Primordial Land soon opened again, and a half-high bronze gate appeared in front of Chu Fengmian.

At the same time, as the gate of the Primordial Land opened, the Primordial Power continued to flow out of it. Chu Fengmian directly activated the Chaos Secret Book and madly devoured the Primordial Power in it.

If Chu Fengmian could enter the Primordial Land now, he would devour the Primordial Power much faster.

However, the opened gate of the Primordial Land was not enough to support Chu Fengmian to enter it. This bronze gate was actually extremely fragile. Once it was affected by a little bit of power, it might be shattered.

With Chu Fengmian's current strength, he could not enter the Primordial Land at all, and now the Primordial Land has returned to the River of Time.

In the River of Time.

If Chu Fengmian entered the Primordial Land at this time, it would be equivalent to entering the River of Time.

No warrior dared to try to enter the long river of time. The power of time would destroy everything. Even though Chu Fengmian now possessed the key of time, he actually had a certain amount of capital to fight against the long river of time.

But he still didn't dare to take risks.

So Chu Fengmian only used the primordial power that kept pouring out of the gate of the primordial land to devour and integrate it into the Chaos Secret Book.

Thirty breaths of time.

The gate of the primordial land began to become illusory, and at the same time, the power of the key of time had reached its limit.

As the power of the key of time was completely exhausted, the gate of the primordial land also shattered and disappeared in front of Chu Fengmian.

At this moment, the power of the sixth level of the Chaos Secret Book in Chu Fengmian's body was finally filled, and Chu Fengmian's Chaos Secret Book finally practiced to the sixth level.

The improvement of each level of the Chaos Secret Book not only made the practice more difficult, but also required more and more power.

Of course, for the warriors of the Chaos Family, this is actually not worth worrying about. After all, even if they lack more power, they can quickly absorb enough by entering the Chaos Pool.

So this point is not marked on the Chaos Secret Book.

But for Chu Fengmian, it has become a thorny problem.

In order to pursue the power of the Chaos Secret Book, Chu Fengmian practiced the Chaos Secret Book in pursuit of the power of the Primordial Power, so the power required for each level of the Chaos Secret Book is to absorb the Primordial Power.

In the first five levels, this problem was not obvious.

But when it came to the sixth level, the Primordial Power obtained by activating the Key of Time to open the Primordial Land was barely enough for the sixth level of the Chaos Secret Book.

And then, the Primordial Power required for the seventh level of the Chaos Secret Book is several times more than that of the sixth level.

This means that even if the Primordial Land is opened once and the Primordial Power is obtained, it is not enough to support the practice of the seventh level of the Chaos Secret Book.

At least the Primordial Land is opened several times.

Or, he could accumulate the blood jade produced in the Blood Abyss for several months, hold a large-scale blood sacrifice ceremony to restore enough power for the Key of Time, and then open the Primordial Land in one fell swoop to obtain enough Primordial Power.

"The Primordial Power required for the seventh level is at least three times that of the sixth level."

Chu Fengmian muttered silently.

If this is the case, Chu Fengmian needs to wait for at least three months, waiting for the blood jade to accumulate for three months in the Blood Abyss, to obtain the Primordial Power required for the seventh level of the Chaos Secret Book.

The speed of practicing the Chaos Secret Book is actually much faster than Chu Fengmian himself had predicted. Chu Fengmian thought that it would take him half a year to practice to the sixth level.

So he temporarily decided to practice to the sixth level.

But now, in just over two months, Chu Fengmian has already practiced to the sixth level of the Chaos Secret Book.

Although the seventh level of the Chaos Secret Book is much more difficult than the sixth level, Chu Fengmian is confident that he can cultivate to the seventh level of the Chaos Secret Book within two months.

But now, even if Chu Fengmian has practiced the Chaos Secret Book to the seventh level, he does not have enough primordial power to recover his strength...

"It seems that the practice of the Chaos Secret Book will have to wait for a while."

Chu Fengmian said to himself.

At least he needs to save enough blood jade before he can continue to practice the Chaos Secret Book.

But it just so happens that this time, the Chaos Saint Emperor found another thing for Chu Fengmian to do, that is, to fight against the chaos.

He does not need to continue to practice hard in this palace.

"There are still twenty days."

The team fighting against the chaos will gather in the Jinjing Territory this time. It will take about ten days to go to the Jinjing Territory from the Chaos Territory, so Chu Fengmian still has twenty days left.

Chu Fengmian did not intend to waste these twenty days. After he put away the Key of Time again, Chu Fengmian did not get up, but his mind moved.

A jade bottle appeared in front of Chu Fengmian again.

Through the jade bottle, you can clearly see a ball of blood in it, and the flame burning on this blood.

This is the blood essence of Li Huang, one of the innate divine beasts in the ancient era.

It is also an unexpected gain that Chu Fengmian found in the blood bank of the Chaos Family.
