Li Changsheng's face became a little pale, but as long as he rested for a few days, the lost vitality would recover as before.

The blood of the Shuangzi King is naturally extraordinary. Under the watering of a large amount of blood, golden patterns began to appear on the two sword boxes.

At this time, Li Changsheng formed a large amount of silver seal script and began to combine the ban on two sword boxes.

Li Changsheng's face became paler and his veins swelled up. At the same time, the combination of two sword boxes almost made his spirit reach its limit.

His mental power was quickly deprived, and he was immediately restored by the Nine Orifices Determination Yuan Bead. It was not until he was about to reach the bottom that he finally completed the ban on the two sword boxes.

However, this is not over yet, and there is a last step.

The next moment, Li Changsheng took out two gourds.

One is filled with the water of the Tianhe River. The so-called Tianhe River refers to the weak water of the nine heavens. Since the heavens are closed, it has been extremely difficult for the outside world to obtain.

This was brought by Li Changsheng from Xinggong. After all, Xinggong is part of the heavenly realm, so there is naturally no shortage of Tianhe River.

Another gourd is filled with yellow spring water, which is produced from the underworld, and you can get it as long as you pay the starting price.

This is also the last step of Lingxiao Sword Box. It must be tempered with special liquids of the same attribute, otherwise all previous efforts will be wasted.

Li Changsheng opened the two gourds, and a slightly silver liquid rushed out of one gourd, while the other gourd was light yellow liquid, which fell on the two sword boxes respectively.

Stop it~

The sound of water and fire is incompatible, accompanied by a large amount of water vapor.

Li Changsheng directly closed the five senses. These water vapors had a certain negative impact. Although they had little impact on him, they were always a trouble.

When the tempering was completed, two Lingxiao sword boxes, one purple and one yellow, rushed out of the Dragon and Phoenix Burning Sky Cauldron.

In addition to the color, the two sword boxes have the same power and are also considered to be a combination treasure.

Judging from the energy fluctuations they emit, both Lingxiao sword boxes have reached the middle-grade purple palace rare level.

If the materials taken from Bernama are not as good as the Demon King-level Purple Sky Kirin, otherwise the Lingxiao Sword Box made with the Demon King-level Purple Sky Kirin as the main material can definitely go a step further, at least reaching the top-grade Purple House rare treasures, or even the best Purple House rare treasures.

However, Li Changsheng still kept a hand. When he found a more suitable material in the future, he could fully develop the Lingxiao Sword Box with Zixiao Qilin as the main material.

In an instant, the two swords of Biluo Huangquan rushed out of the sea of ​​consciousness and fell into their respective Lingxiao sword boxes.

Next, it is the experiment.

After obtaining the method of refining Lingxiao Sword Box, the Sun True Lord never refined it because this guy did not have a powerful sword-like treasure, so he put it on the shelf.

After continuous experiments, Li Changsheng found that it was not possible to greatly increase the power by inserting the sword into the Lingxiao sword box and pulling it out. It also had a certain cooling time, otherwise it would be too perverted.

After the test, Li Changsheng found that the sword needed to be kept in the Lingxiao sword box for an hour before it could greatly increase the power of the sword when it was pulled out.

The cooling time seems to be not long, but the battle between the demon masters has always been very fast, and there are rarely an hour of battle. Moreover, Li Changsheng can't always insert the Biluo Huangquan double swords into the Lingxiao sword box without using it.

In this case, it is almost equivalent to only exerting the effect of the Lingxiao Sword Box once per battle.

Even so, Li Changsheng was very satisfied.

The combination of Biluo Huangquan's two swords is already extremely powerful. With the significant bonus of Lingxiao Sword Box, the power it has can be imagined, and it can definitely catch the enemy off guard.

Li Changsheng put away his sword box and sword, and rested in the secret realm for a few days before returning to his heyday.

On this day, Li Changsheng and Ning Bizhen left the secret realm, and he also had to accompany Ning Bizhen to a long journey.

There is no reason. Ning Bizhen's mental power has reached the peak of the king, and she can try to break through to the double-character king.

Li Changsheng did not go to the territory of the North Dragon King Ao Run. After all, if the two double-character kings broke through in the same place, it would be too conspicuous.

This time, Li Changsheng decided to let Ning Bizhen try to make a breakthrough in the South China Sea.

The two left Langya Kingdom without knowing it. In just one or two hours, they landed on a deserted island outside the South China Sea.

Li Changsheng stretched out his hand and waved it, and 365 stars were scattered and landed in different positions.

Since the sun and star coils have been completely restored, and Ning Bizhen's Taiyin and star coils, Li Changsheng directly chose to replace them, which further furthered the power of the Hunyuan Heluo Forbidden Array.

The only drawback is that the purple myrtle stars are covered by the sun and the moon is completely overwhelmed, which gives people a feeling that the king is weak and the minister is strong.

Li Changsheng did not have the idea of ​​refining the Ziwei Star Pan again, and the main reason was that there was no suitable material.

The most important thing is that he believes that as long as he accumulates for a while, he can win the inheritance of the Star Emperor. At that time, Ziwei and Xingchen Pan are naturally no problem.

Under the protection of Li Changsheng, Ning Bizhen began to try to make breakthroughs.

Just a few days ago, Li Changsheng organized another collective breakthrough, but it was mainly Ning Bizhen's demon pet.

During this breakthrough, Li Changsheng's paradise double-pupil bird successfully broke through the Demon Saint level and became the third temporary demon pet at the Demon Saint level after the Wanxiang Spirit-Devouring Rat and the second ancestor of the Red Dragon.

As for the only Qionglong among the main demon pets that has not yet reached the level of the demon saint, it has not yet met the breakthrough requirements.

Ning Bizhen also had a demon pet to complete the breakthrough, and there were two, namely the Eight-Eyed Mink and the Light Dragon Horse.

In this way, Ning Bizhen has a total of seven demon holy-level demon pets, which completely met the breakthrough requirements.

With Ning Bizhen's conditions, although the breakthrough success rate is not as good as Li Changsheng, it is only 80% or 100% of them.

Unexpectedly, after an hour, Ning Bizhen easily completed the breakthrough and became a more noble double-character king.

At this moment, the heaven and earth began to celebrate the birth of another two-character king.

In this process, Xuan Emperor is naturally indispensable to control the Queen Mother's Mirror clone to come to investigate.

Unfortunately, Emperor Xuan was destined to see nothing.

Like Li Changsheng, Ning Bizhen also chose to hide it. Her consciousness did not enter the Hall of Ten Thousand Kings, and no one would know that she had become the Double-word King for the time being.

Of course, this can only be hidden for one year.

After becoming the queen of Shuangzi, Ning Bizhen's secret realm expanded rapidly, but it still did not become a blessed land until it slowed down, and it was still a distance away from the standard of blessed land.

This is mainly because of the fact that the foundation is too shallow. Li Changsheng also relies on a large number of top spiritual roots, which can make the secret realm quickly become a blessed place.

Before leaving, Li Changsheng used the great deduction technique to calculate it. After confirming that no one was surveillance, he asked Ning Bizhen to continue to stay in his secret realm, while he secretly sneaked out of the unmanned island.
