By increasing the dark power in his body, he can no longer transform back into his original Ultra Warrior form, in order to completely shatter his heart.

At that time, Dark Tiga will be able to take advantage of the situation and achieve his goal easily, whether it is brainwashing or anything else.

"Hmph, Dark Tiga, if that's all, then you underestimate me and our Kingdom of Light."

Seven snorted in his heart, thinking he had already understood Dark Tiga's tricks.

If his guess was correct, Dark Tiga intended to start with the Ultra Brothers, transforming them into dark giants, and use this as a breakthrough to seize the Kingdom of Light.

"I will not let you succeed, Dark Tiga! Even if I will be completely transformed into a dark giant, the enthusiasm in my heart will never be extinguished. Just watch me!"

The fighting spirit in Seven's heart burned fiercely. At this moment, he no longer looked back and forth, but was ready to fight a battle of faith with Dark Tiga.

Aren’t you, Dark Tiga, going to transform me into a dark giant in order to shatter my mind?

Then I will let you see carefully that even if I am trapped in darkness, I will still embrace the light!

While thinking this in his heart, Seven actively drove the dark power to purify the dark aura.

Leo, who was standing by, just watched as more and more dark aura rushed towards Seven, wrapping him into a black sphere.

"Is this situation really okay?"

Feeling Seven's breath becoming stronger and stronger with the continuous influx of dark aura, Leo couldn't help but swallow secretly.

In order to conserve the energy in his body, Leo immediately chose to temporarily cancel his transformation and hide aside to check the situation.

In this way, if Seven loses control, he will still have the energy to stop Seven instead of just watching from the side.

Just like this, Feng Yuan braved the scorching sun of the desert, always observing Seven's situation, his heart full of worry.

As for Feng Yuan's behavior of canceling his transformation, Seven did not make any comment. He just silently purified the dark aura that seemed to be continuously penetrating into his body. At the same time, he also divided his mind and began to remove the remaining mark of Dark Tiga from the dark power in his body.

Once he has completely mastered the dark power in his body, Dark Tiga will no longer be able to control his body as easily as before.

As for the dark power that he had always rejected and hated, when Seven looked at it now, he no longer had the same hatred and disgust as before.

Perhaps, this is because he is in an extremely rational state now, so he avoids the influence of those emotional emotions.

Besides, the situation is not favorable now, and Seven has reasons to do so.

Otherwise, if Dark Tiga comes to forcibly control his body again, can Leo withstand it?

As I thought about this, time passed quietly.

The dark aura did not continue to flow as Seven had imagined. After reaching a certain level, no more dark aura appeared underground in the desert.

As to whether this means that the dark aura hidden on the earth has been completely purified by Seven, we can only ask the will of the earth.

Seeing that no more dark energy was pouring in, Seven slowly took back the dark power released outside his body.

After a while, Seven's figure appeared again under the scorching sun of the desert.

But compared to before, Seven felt that his strength had increased significantly.

"This is really..."

Seven clenched his fists and felt the intensity of the energy in his body at the moment, and couldn't help but whisper.

It seems that he can now activate X-form again.

I just don't know if using the power of X-form in dark form can give me the advantage in the battle with Dark Tiga as I did before.

After all, Seven's strength has basically been declining over the years. Even though the energy in his body has increased after purifying the dark aura, he is still standing still compared to before.

On the other hand, Dark Tiga's strength has been greatly improved compared to before.

Conservatively speaking, if he uses the X form, he will only be qualified to fight Dark Tiga. To defeat and destroy Dark Tiga like last time... it's difficult!

But this is not impossible. Compared to him who fought alone during the Ultra Guard period, there is now Leo on the Earth, and there is also a Tiga who was abducted by Dark Tiga.

Next, they just need to let Gu Chen train Leo step by step, and then find a way to rescue Tiga. It is not impossible for them to defeat Dark Tiga.

Seven no longer expected to kill Dark Tiga like he did before. He would be satisfied if he could drive Dark Tiga away from the earth.

"Captain, are you done?"

At this moment, Feng Yuan's voice came from a distance, penetrated into Seven's ears, and interrupted his thoughts.

"It's done, let's go back."

As Seven spoke, he took a few steps towards Feng Yuan, squatted down and spread out his palms.

Feng Yuan brought him here, so when he leaves, he should take Feng Yuan back with him.

Now that Seven has made up his mind and no longer rejects the dark power in his body, his mentality has returned to normal and has changed.

Looking at the dark hand that stretched across his body, Feng Yuan swallowed again.

He was thinking now, what if after he goes up, Seven suddenly clenched his fists, wouldn’t he not even have the chance to transform and would be crushed by Seven directly?

"Don't worry, I can control myself. Give me some confidence, Yuan."

As if he could see the worry in Feng Yuan's heart, Seven couldn't help feeling helpless and amused.

Is he now beginning to have the same fear-inducing aura as Dark Tiga?

"Yes, Captain, I'm so sorry."

Feng Yuan, whose thoughts were seen through by Seven, immediately bent down a little embarrassedly, then jumped onto Seven's palm swiftly.

Then, Seven held Feng Yuan with his hands, just as Feng Yuan held him at the beginning, slowly stood up, and prepared to return to the MAC team's headquarters base.

After all, what happened here is over, and staying here any longer would just be a waste of time.

However, at this moment, the sunlight in the desert, which was originally shining brightly, suddenly dimmed, as if it was blocked by something.

The next second, a hundred-meter-long bust of Dark Tiga appeared in front of Seven and Feng Yuan.

"Hey, little Seven, it seems that you have finally figured it out. How about it? Dark power is not worse than light power at all, right? In fact, on this earth, dark power is much more useful than light power."

As soon as Dark Tiga came up, he started acting in his usual weird way.

"Dark Tiga, I have seen through your conspiracy and you will not succeed!"

However, this time, facing the sarcasm of Dark Tiga, Seven did not go berserk like before, but stood calmly in place and shouted at Dark Tiga in a firm tone.
