I became a villain in a book. Why did the heroine turn evil first?

The spiritual energy contained in this sea of ​​energy was no less than the spiritual energy in her current twenty-one star vortexes. If we only talk about the spiritual energy reserves, she is definitely the best in the same level.

However, while Mu Wuyi was cultivating her Qi Sea, she also discovered another problem: the Qi Sea in her Dantian had expanded to its limit. How should she cultivate next?

According to the Cangyun Realm's cultivation system, she only needed to continuously open up the Star Whirlpool. However, with the Dantian Qi Sea cultivation method, she only had one Dantian and could only condense a Qi Sea.

But Mu Wuyi wasn't too worried. She had a feeling that she would know the answer when she reached the fourth floor. And the owner of that voice would definitely not leave her alone.

"Um... Senior, I have already condensed the Qi Sea. Can I go to the fourth floor?"

Mu Wuyi said something to the air in front of her, but she knew that the mysterious existence must be paying attention to her all the time.

Sure enough, as soon as she finished asking the question, the voice sounded again.

"Yes, your training speed is much faster than I expected. Let's go to the fourth floor."

After the other four people from the Green Water Palace joined together, they continued to act together. After all, their combined efforts to perform the Green Water Palace's sword formation and hunt down exotic beasts were much more efficient than if they acted alone.

It's just that they have been staying in the restricted area for the past few days. It's not because they have enough exotic beast cores, but because Mu Wuyi hasn't appeared yet, which makes them a little worried. Although the time limit has passed, they still want to wait and see if there will be any miracle.

As a result, they really got what they were waiting for.

At this time, the four of them just sat together, originally intending to discuss the next plan. But before anyone could speak, a teleportation array suddenly appeared in the open space between the four of them, and then a flash of light appeared, and Mu Wuyi's figure appeared in front of them.

"Hmm? What a coincidence, everyone is here."

Mu Wuyi was also a little surprised. He didn't expect to meet Su Yunyao and the others just after arriving at the fourth floor. Moreover, all of them were there.

"Senior sister!"

"No support!"

"Great, because the time limit for the first three levels has already passed, and we thought you were eliminated. Why did you show up now?"

Hearing Dongfang Zhiyun's question, Mu Wuyi raised his eyebrows and replied.

"Uh, did I encounter some... accidents? Not important, I'm now on the fourth floor anyway."

Mu Wuyi didn't tell the truth directly because the voice just now reminded her that it would be better to wait until she passed the sixth level before telling them the truth. Moreover, Mu Wuyi didn't dare to speak carelessly about such a major matter as the cultivation system.

After knowing the trial rules of the fourth level, Mu Wuyi asked.

"What are your plans for the future? How many beast cores have you accumulated?"

Dongfang Zhiyun pointed to the stone tablet in the center of the restriction and replied.

"The number of exotic beast cores is displayed on the stone tablet. We were just about to discuss the next plan, and then you suddenly appeared."

At this time, Chu Xiaoxiao interrupted.

"Since Mu Wuyi is here, what else do we have to discuss? The sword formation formed by the five of us should be able to kill even the first or second level beasts of the Xuanxian Realm. What's the point of planning? We can just rush out and kill them."

In the past two months, Chu Xiaoxiao has become addicted to playing with the sword formation. From the initial "What's the point of learning this sword formation", it has become "When in doubt, use the sword formation." This is really the law that everything in the world cannot escape the true fragrance.

Although Chu Xiaoxiao's proposal seemed a bit reckless, everyone thought it was not impossible. Before, when there were four of them, Zhi Liangmeng led the sword formation and could fight against the first-level beasts of the Xuanxian Realm. Now that Mu Wuyi has joined, maybe they can really compete with the second-level beasts of the Xuanxian Realm.

As for the higher level beasts, they are rare in the fourth floor and it seems that no one has encountered them yet.

In the end, everyone really adopted Chu Xiaoxiao's suggestion and rushed out directly.

After killing the first beast, Mu Wuyi held the beast core in her hand and pondered. After a moment, she suddenly realized how to practice after she knew the Qi Sea, and this beast core was the answer.

At this moment, the previous voice sounded in Mu Wuyi's ears again.

"You have a good understanding. The correct name for this beast core should be Yuan Dan. When Yuan Dan is formed, it is the realm after Qi Hai. Condensing the sea into a pearl, the thunder falls into a pill!"

Mu Wuyi could understand the sea forming a pearl, but this thunder falling into a pill, could it be that in order to form a Yuandan, one must also go through a thunder tribulation? The cultivators in the Cangyun Realm only need to go through a heavenly tribulation to ascend to heaven, and I have never heard that the previous realms still need to go through a thunder tribulation.

"That's why I said that the cultivation system of the Cangyun Realm is a trick. To form a pill, you need the assistance of the purple energy in the heavenly tribulation, and you must survive three thunder tribulations. If you succeed, you will have a bright future, but if you fail, you will die. This is the true way to cultivate immortality."

Hearing this, Mu Wuyi's eyes widened: What?! If I fail, I will die? Forget it. Her original goal was to live for a hundred years in this world. But this body is only twenty years old, and it is still a long way to go before a hundred years. She would rather choose to live a short life than take this risk.

However, Mu Wuyi's thoughts could not be hidden from the owner of that voice, so he spoke again.

"Don't worry. With your aptitude, it will be very easy to survive the Dan-forming Tribulation. I can guarantee this with this inheritance. If you succeed in forming the Dan, you will have two cultivation systems, and the spiritual energy in your body will be twice that of people at the same level. By then, you will be invincible at the same level."

For such a powerful person, inheritance is extremely important. He dared to make such a guarantee, which means that in his opinion, Mu Wuyi's success in overcoming the tribulation is inevitable. Moreover, the fact that he is invincible at the same level also makes Mu Wuyi very excited.

If this is true, coupled with the help from Bai Hua and Mo Ran, maybe she can really change her fate. After all, she finally came to the world of immortal cultivation. If there is a choice, who doesn't want to be an immortal for fun?

"Sister, what are you thinking about?"

Su Yunyao saw that Mu Wuyi had taken the alien beast core and had been staring at it in a daze, so she couldn't help but come up and ask. Mu Wuyi's thoughts were interrupted, and he looked at Su Yunyao in front of him, then gritted his teeth and spoke.

"Yun Yao, I need to practice for a while, can you help me protect the magic?"

An hour later, a Yuandan had condensed into shape on Mu Wuyi's Qi Sea. At the same time, outside, above the inheritance tower, a large thundercloud suddenly gathered, and purple lightning snakes swallowed and spit in the clouds, as if containing some great terror.

Ji Mingting looked at the thunderclouds in the sky in surprise. Although he had not experienced it personally, he had observed it before. This was a calamity from heaven!
