Because as Chen Feng's true energy continued to pour into the formation, he easily refined wherever he went, and the whole process was simple and he felt incredible.

But after thinking about it, Chen Feng understood the reason. When this formation was set up, there must be a special guard, and even the formation could be controlled by the head of the Suxin Sword Sect.

However, as the spiritual energy of heaven and earth gradually dried up, the Suxin Sword Sect fell, and then the disciples scattered, and of course no one guarded the place anymore. As for this formation, it gradually became a masterpiece as the years passed.

Now that Chen Feng released his true energy and wanted to refine it, he would certainly not suffer any resistance. It can be considered that he had picked up a big advantage for nothing.

As a result, Chen Feng worked harder and tried his best to activate his true energy. Not only did he refine his half-formation, but he also penetrated into Lan Changtai's half-formation.

If Lan Changtai was vigilant and activated the true energy to stop it in time, then he could resist Chen Feng's refining of the formation and at least half of it could be saved. This was like two doors he saved one, even if it was inconvenient to enter and exit, at least he would not be completely controlled by others.

But Lan Changtai didn't realize this at all. He was still immersed in his complacency and satisfaction of plotting against Chen Feng, especially when he looked at Chen Feng's gloomy face, he felt extremely relieved.

Thinking that Chen Feng almost destroyed Qingyang Mountain, but the coward in Bianlei actually let him leave alive, Lan Changtai couldn't help but despise Bianlei again when he hated Chen Feng, and said to himself: "After all, I have to see me. Not only can I open the secret realm and open the passage, but I can also kill Chen Feng to eliminate future troubles. As for Bianlei, huh, it's just a waste."

Just as he was so proud, Chen Feng's true energy was spreading rapidly in the formation and refining every place and every rune.

Lan Changtai felt Chen Feng's true energy pouring in, and was slightly surprised in his heart why his true energy came so quickly, but he didn't go to his heart. He even thought gloatingly: The more you want to activate the formation as soon as possible, the more true energy you will consume, and I will be able to kill you more easily later.

But before Lan Changtai's pride lasted for a long time, he instinctively felt a trace of uneasiness surge into his heart, especially when he saw Chen Feng, who had been lowering his head, suddenly raised his head, and his face was full of sneer, he felt unprecedented shock.

"What are you thinking?!" Lan Changtai asked subconsciously, and then he found that his body was entangled by a long chain condensed from runes extended from the formation. Then an extremely powerful suction force burst out from the runes on the long chain.

At this moment, Lan Changtai suddenly felt like he was in a position and was inverted with Chen Feng. Why was the one who was being crazily absorbed by the true energy turned into the self who should have stood by and watched the fun?

"What's going on?! Why did it turn out like this??" Lan Changtai felt like he was having a nightmare. What made him even more uneasy was that he used the secret method in Qingyang Sect, but he could not get rid of the constraints of these long runes chains on himself, as if it was completely out of his control.

"The formation is out of control? How is this possible? This is the formation set up by my Qingyang Sect..." Suddenly, some thoughts flashed through Lan Changtai's mind, and his face suddenly became extremely ugly.

He activated the true energy that was constantly being sucked away, and wanted to communicate the runes in the formation, but he could not get any response at all, as if he had nothing to do with him.

In fact, Lan Changtai could have used Qingyang Gate to try out the inherited method of driving formation, but now it has lost its effect.

Lan Changtai is not a rookie, so he immediately understood that this was because the control of the formation had changed hands.

"Damn it! When did this guy Chen Feng secretly take control of the formation? Could it be that it was just now, how long did it last?" Lan Changtai remembered the scene of Chen Feng trying hard to send his true energy into the formation, and immediately guessed the reason, but he was even more shocked and depressed.

If he knew that the formation here was so easy to refine, how could he wait for Chen Feng to do it? He would have already refine it first.

Lan Changtai knew how much the benefits of controlling such a formation that acted as a secret realm portal. It was like controlling the secret realm in his own hands.

"Hiss." At this point, Lan Changtai subconsciously took a breath of cold air because he thought of a very terrible possibility.

Lan Changtai suddenly looked at Chen Feng and found that he was looking at him with a cold look, which made his inner extraordinary become stronger.

"Chen Feng, what are you trying to do?!" Lan Changtai asked pretending to be puzzled.

"I just see if you work hard or not, it's really unreasonable, so I urge you to rest assured. When you let the formation be fully operated, you will naturally be able to regain your freedom." Chen Feng said lightly.

"Damn, by that time, how much true energy can be left in my body? Wouldn't it be like fish on the chopping board for you to slaughter?" Lan Changtai cursed in his heart, but had to smile and said, "How could it be? I said it naturally, it would be better for you to let me go first."

"If you have time to talk nonsense to me, you might as well work harder." Chen Feng said coldly.

Lan Changtai cursed inwardly but did not do anything to Chen Feng. Especially after feeling the speed of loss of true energy in his body increased, he had to deal with it carefully.

He didn't dare to do anything perfunctorily now, because if he refused to send his true energy into the formation, the formation would suck the essence in his body until he died. This is also the ruthlessness of this formation. He wanted to use this to trick Chen Feng before, but he didn't expect that he would suffer the consequences now. It was really a bit like a cycle of heaven and retribution.

Although Chen Feng activated the formation to suck Lan Changtai's true energy with all his strength, he did not stop inputting the true energy into the formation.

First, Chen Feng can convert life energy into true energy, so he is not worried about lacking true energy, so he naturally does not have to be stingy. Second, because he has tasted the sweetness now, not only wants to continue to refine the formation, but also wants to control the secret realm connected to it through the formation.

If he can take the secret realm for himself in one fell swoop, he will make a lot of money, because this is equivalent to having a private secret realm. At that time, it will definitely be a pleasure to treat it as a place to live or a huge storage space.

If you were to go to Yuanling Continent, Chen Feng might not have such an idea. First, you may not be able to think about it, and second, you may not dare to think about it if you want it.

After all, having a storage bag is already a great thing for today's practitioners. Who can use a secret realm as a storage space?!

You should know that although the space in the secret realm is large and can store living things, it is impossible to carry it with you like a storage magic weapon. This undoubtedly makes it quite inconvenient, unless it has powerful space-based spells, you can tear open the void and connect it to the secret realm space anytime and anywhere.

Chen Feng couldn't do it in the past, but now he has the possibility of doing it. At the same time, the current conditions allow it, almost a ready-made secret realm is delivered to his door, so he naturally won't miss it.

However, after constantly testing, Chen Feng was surprised to find that the formation that acted as a portal had become a masterless thing that anyone could refine. However, the secret realm in the formation could not be opened easily, and the defense restrictions inside were still dense, layered and intertwined, giving people a feeling of impeccableness.

The only ones that can enter and exit are those evil ghosts. If a living person wants to pass, he will either die under the ban and fight back or be crushed by the turbulent flow of the void.

"The Qingyang Sect Formation Master did have some skills. He could find such a secret realm and set up such a strict ban, but he didn't know what he was guarding against. He could not even be a powerful person in the imperial realm, otherwise he would have been in danger for a lifetime." Chen Feng thought to himself, but he became more and more curious.

Just as Chen Feng tried repeatedly, more than half of the true energy in Lan Changtai's body had been pulled away by the formation.

In other words, Lan Changtai has the power of the Emperor Realm, and can absorb a large amount of spiritual energy in the world and turn it into true energy during breathing and breathing. Otherwise, it may not be drained from long.

Even so, Lan Changtai couldn't hold on for too long. After all, no matter how fast he absorbed spiritual energy, it was far faster than the speed of true energy loss. When the true energy in his body was exhausted, the formation would inevitably absorb his essence and life energy.

"Chen Feng, I admit defeat. How can you let me go?" Lan Changtai looked at Chen Feng, who lowered his head and said silently, his expression was not changing. He didn't know what he was thinking. After hesitating for a moment, he finally decided to admit defeat.

Of course, Lan Changtai felt embarrassing to bow his head and admit defeat, especially when facing a younger generation who was much younger than him. However, he understood more that although face is important, life is more important. If he really dies like this, then no matter how strong his backbone is, it is useless.

"Why do you have to say that?" After a long time, when Lan Changtai thought Chen Feng hadn't heard him speak, he suddenly said: "I don't have many requests, I just asked you to fulfill your previous agreement, and agreed to activate the formation here and open the secret realm together. How can you be lazy?"

"My true energy is not much left. I lost this time. What if I let me go, the conditions will be up to you." Since I decided to admit defeat to protect my strength, Lan Changtai would not give up easily.

"If you persist, then okay, tell me what purpose do you want to open the secret realm here?" Chen Feng looked at Lan Changtai and said, "You can only be qualified to continue talking to me if you tell the truth."

"I'm really for my junior sister." Lan Changtai said.

Before he finished speaking, he groaned, and at the same time, he gritted his teeth and made a sound of pain.

Because the formation had suddenly increased its suction power on his true energy just now, the feeling of being sucked dry in an instant was absolutely unpleasant.

But Lan Changtai remained silent, as if his purpose was really just to release the warm heart that he had claimed to be in the secret realm.
