Babel Tower is worthy of being a treasure of feng shui for cultivating martial arts experience, in just two days, with the 15% bonus of the actual combat martial arts experience of the reincarnated prodigy, he has practiced the peerless martial arts grade "Imperial Ghost Demon Emperor Dragon Technique" to the fourth layer.

Because of the relationship of "Three-Yuan Quenching Body", his current meridian system is very different from before, and other places are fine, the key is in the dantian qi sea, after being divided into three, there have been many changes in the way of luck.

At this stage, he was still using the overflowing power, and he did not use the sea of qi. But after Monday, the overflow power will be dissipated, and then you will need to do your own luck.

In fact, all of this can be directly guided by the system, and the player does not need to control it alone. But since Yu Feng accepted Bu Xiyue's account, he has always been doing his own luck, and if he uses the system to guide him directly, he feels uncomfortable.

In fact, if he wants to make the same detailed changes as when he was studying with Bu Xiyue before, it is really not possible to rely on the guidance of the system.

In addition, in terms of practice, he also felt that if he practiced qi, the conversion rate of martial arts experience would be higher, of course, this was just his own feeling, and the actual number could not be measured.

Since Saturday afternoon, Yu Feng has basically not left the Tower of Babel, until the next day, after entering the fourth layer of cultivation, he returned to Xiaoyao City.

Because of the abundant funds, he always has all kinds of medicines to replenish qi and return blood, and there are also a lot of pills with a buff effect, but he usually uses them relatively rarely. This time, when he returned to the city this time, he prepared a lot of Qi Rejuvenation Divine Pills.

In the courtyard rented by Bu Xiyue, he took out the black bark.

"Can you see what's wrong?" Yu Feng asked.

Bu Xiyue has been online all day these two days, but she seems to be busy with other things, and she was specially called by Yu Feng today.

"There shouldn't be anything wrong with the ghost clan, but my "Haotian Forbidden Yuan" and "Nine Doom Spirit Yuan" can't be opened, so it shouldn't be the real bark." Bu Xiyue said.

"Nine Spirits" and "Haotian Forbidden Yuan" are both her skills, and in order to practice these two skills at the same time, she will need a male number. Because only those who have cultivated the "Shu Yan Jianxin Formula" can have the ability to merge these two skills. And "Shu Yan Jianxin Jue" can only be practiced by the male horn after breaking the roots, and after going around, it turns out that she needs the male horn to practice three different martial arts.

This was revealed by Yu Feng when she chatted with her after going offline last night. As for why she can still find these three martial arts that look awesome after changing the number, she didn't reveal too much, she just said that it was complicated to explain, and she would talk about it when she had time.

Among them, "Nine Doom Lingyuan" is the cultivation of heaven and earth aura, can communicate with the spirit of nature, if the black bark is a plant, more or less Bu Xiyue can find out a little information.

Since there is no response, it is said that this bark actually has no plant properties at all.

As for "Haotian Forbidden Yuan", it is a very mysterious and ancient forbidden martial arts, as far as we know, except for the martial arts that come with the martial arts, there is no martial arts or strange magic that can match it. But Bu Xiyue said that it has another role, if it goes well, "Haotian Forbidden Yuan" will greatly increase the chances of winning the battle of Zhelan Mansion!

In fact, Yu Feng heard it at first glance, and felt that Bu Xiyue was a lot of work, it was better to practice it herself, she had two internal elements, but Yu Feng now has three!

But that's not how the account is calculated, this thing is not too much. "Three-element Quenching Body", "Haotian Forbidden Yuan" and "Nine Spirits" are all gong bodies, and the gong bodies all have different attributes and skills.

For example, when "Three-Yuan Quenching Body" was successful, according to the three internal elements, the "Royal Ghost Demon Emperor Dragon Jue" with a long and middle two name was formed.

"Nine Spirits" and "Haotian Forbidden Yuan" are the same, they also have internal strength and martial arts supporting the body. Coupled with the "Shu Yan Jianxin Formula" that is used to synthesize the two types of martial arts, in terms of martial arts, even Yu Feng, who is a three-dimensional body, can't compare.

The "Shu Yan Jianxin Jue" is by no means an ordinary martial art, when the body is added, the original internal strength will be abolished, and the internal strength will be replaced with a special body. However, instead of being replaced, "Shu Yan Jianxin Jue" also took into account two completely different physical constitutions at the same time, which is simply magical.

Hearing that Bu Xiyue also said that there was no way to open it, Yu Feng couldn't help frowning.

"You continue to infuse with the Ghost Yuan, and I'll help you replenish your strength this time." Bu Xiyue said.

Last night they would talk about their respective bodies, and it was because of this black bark.

After Yu Feng finished brushing the Tower of Babel, he pondered about activating this thing that he bought for 50,000 taels, he tested all his skills, and found that the bark only absorbed ghost qi, and did not even absorb so much of the internal force converted from earth qi that overflowed! So he could only infuse all the ghost energy into it.

But the cheating dad thing happened, and after this thing absorbed the ghost energy, it didn't react at all! By the time Yu Feng found the Babel Tower NPC to spend money to restore his strength and planned to continue the infusion, the ghost qi that had been infused before had completely disappeared.

Then, he went offline to discuss with Bu Xiyue, and by the way, he learned about the martial arts information of Bu Xiyue.

The result of their discussion was that there might be too little ghost energy to feed the bark.

Today, Yu Feng frantically brushed the Tower of Babel for a day, and raised his internal strength to the fourth layer in order to have a little more ghost energy.

Bu Xiyue's "Shu Yan Jianxin Jue" is very special, and it can be combined with the special skill of "Nine Doom Lingyuan" to achieve the effect of supplementing the internal force of any attribute.

The skills of the two people, coupled with a bunch of qi rejuvenation elixirs, Yu Feng didn't believe that he couldn't feed this broken bark!

Ti Yuan accepted Qi, the Ghost Yuan operated, and the Sen Sen Ghost Qi was forced out of his palm, and then it was absorbed in the blink of an eye.

Yu Feng immediately swallowed two top-grade Qi Rejuvenation Pills and continued to breathe.

Although the overflowing power is easy to use, it can only be used, not absorbed or transformed, which is a pity.

In the case of taking medicine and exercising his strength, Yu Feng barely supported it for a few minutes, and Bu Xiyue saw that he was almost at the limit, so he moved behind him and used his unique internal strength to penetrate his qi and restore the ghost qi within the ghost yuan.

Yu Feng took medicine, she was not short of medicinal pills, and the two of them had a hard life for more than ten minutes!

However, the bark of the tree still did not react except after absorbing the ghost qi.

"Why don't we take this thing to the realm of Zhelan Mansion and see if it can absorb the ghost qi there?" Yu Feng said casually. He was already starting to be disappointed, this thing had too much appetite, and the combined skills of the two of them were still not enough.

"Hold on a little longer." Bu Xiyue didn't want to fail like this.

Yu Feng naturally didn't want to give up, anyway, the two of them had already taken a few thousand pills, so if they insisted for a while, they would hold on for a while, they would have to think about it a little after all.

After another two minutes, the internal force went in and out, and the Rejuvenation Divine Pill couldn't hold on.

Just when the two of them were about to run out of oil, the black bark suddenly burst out with a burst of black gas.

Seeing this, Bu Xiyue hurriedly retreated!
