Looking at the synthesis route in the synthesis column, Su Yu raised his eyebrows slightly.

Just because, in addition to these four martial arts, Su Yu also saw a brand new synthesis route.

[Synthetic route of the divine thunder holy body: synthesize the star field thunder heart and advance to the star thunder immortal body. This is the cosmic level physical body cultivation route. After the star thunder immortal body is completed, the star field will not be destroyed, and I will be immortal!

】

Looking at the introduction of the system synthesis route, Su Yu's eyes lit up slightly.

Immediately he opened his identity token and found the location of Star Territory Thunder Heart in the redemption list.

But after seeing the price, Su Yu silently closed the exchange list.

Star Territory Thunder Heart exchange requirements: 100 million prehistoric points!

The corners of Su Yu's mouth twitched slightly.

Good guy, it’s so expensive.

From joining the Prehistoric Branch to now, Su Yu has only earned a few million Prehistoric Points.

Moreover, these millions of dollars are not spent once they are earned.

Su Yu needs to spend a lot of prehistoric points every month to activate the Starry Sky Spirit Gathering Array and his own Nine Heavens Spirit Gathering Array.

At the beginning, I extorted a lot of high-grade boundary stones from the Purple Sky Leopard, so that I could satisfy Su Yu's practice some time ago.

And now...

All the high-grade boundary stones extorted from Zitianbao have been spent.

This also leads to the fact that if Su Yu wants to continue to start the Nine Heavens Spirit Gathering Formation now, he will need to spend prehistoric points to purchase boundary stone fragments.

Therefore, the prehistoric point is still a difficult problem for Su Yu.

"Forget it, let's improve ourselves first. We still have the ten days in the Primordial Secret Realm, which we still have to use!"

Su Yu murmured, and then exchanged enough boundary stone fragments and synthesized them all into top-grade boundary stones. After that, Su Yu went to the ancient secret realm.

He has ten days of practice time in the Primordial Secret Realm. Calculated, it is equivalent to being able to practice in the Primordial Secret Realm for a thousand days.

It's equivalent to three years.

Coupled with the existence of his own Nine Heavens Spirit Gathering Formation...

Su Yu didn't know how he would change completely after these ten days.

Su Yu arrived at the ancient secret realm with ease. After handing his identity token to the old man, he was allowed to enter.

Entering the ancient secret realm, Su Yu sat cross-legged on the top of the mountain, the "True Secret of Innate Chaos" in his body slowly began to circulate, and the Nine Heavens Spirit Gathering Formation was activated in an instant.

The power of the world around him instantly became extremely intense and terrifying.

It is worth mentioning that as Su Yu has cultivated his "True Art of Innate Chaos" to the third level, Su Yu's ability to absorb the power of the world has also accelerated by an unknown amount.

even……

Su Yu absorbs the power of the world for one day, which is equivalent to what others absorb for ten days.

After all, it is still a cosmic-level technique, extremely domineering!

…

Deep in the Honghuang Branch.

The dean was still sitting cross-legged by the lake, and beside him, the figure of Taoist Heiyu slowly emerged.

"Dean, there is a message from the Ninth Academy of Starry Sky. Do you want to read it?"

Listening to Taoist Heiyu's voice, the dean slowly opened his eyes.

"explain!"

Taoist Heiyu said respectfully: "The information from the Ninth Academy of the Starry Sky says that a low-level ancient ruin will be born near the prehistoric star field. This ancient ruin can only accommodate the entry of powerful people under the Celestial Realm. The Ninth Academy of the Starry Sky

The Ninth Academy requires the nearby branches to send people to bring out as many things as possible from the ancient ruins. When the time comes, rewards will be given based on the amount of things brought out!"

"Ancient ruins..."

A ray of light suddenly shot out from the dean's eyes.

"I didn't expect that ancient ruins could be born here in the prehistoric star field. How long ago?"

"In half a month!"

"In this case, let the sequence of the Honghuang Branch take action!"

After the dean finished speaking, he looked at Taoist Heiyu.

Taoist Heiyu's expression was slightly strange. He looked at the dean and said softly: "Dean, is Su Yu going too? He is only in the middle stage of the Immortal Realm. If he is allowed in, will..."

Taoist Heiyu has not finished what he said next.

Ancient ruins are relics left over from the powerful men of ancient times. They contain many ancient techniques and martial arts, which are extremely precious.

Of course, not

It is said that ancient things must be good.

But with the passage of time for such a long time, many inheritances have been cut off in the long river of time. If you want to obtain those special inheritances and inherit them, you can only do it in ancient ruins.

Ancient ruins are also divided into levels, and ancient ruins of different levels have different strengths and weaknesses in inheritance.

Low-level ancient ruins can be said to be the most inferior ancient ruins, and the inheritance here is basically some side inheritance.

But even so, if it can be inherited, it will still have unexpected effects.

Therefore, even the Ninth Academy of Starry Sky is more concerned about it.

It's just that here, just like the Immortal Secret Realm, if someone dies in the ancient ruins, people outside will have no idea who did it.

Thus……

Many times, some people have a grudge, but because of the background behind the other party, they dare not take action.

But after entering the ancient ruins, there will be a killing spree.

At that point, it will be more troublesome.

And Su Yu...

It has received a lot of attention.

The dean's eyes thought for a moment. To be honest, he had almost forgotten that Su Yu was behind him, but there were several pairs of eyes staring at him.

So I didn't react at first.

but……

The dean was relieved when he thought that Su Yu could get the origin of the world from the hands of the Crazy Blade Palace.

“How can you see a rainbow if you don’t experience wind and rain?”

"The little guy needs training. If I remember correctly, he has already entered the ancient secret realm. Ten days is enough for this guy to improve a lot."

"In this way, except for the first sequence, all sequences will enter the ancient ruins!"

Seeing how firm his dean was and his trust in Su Yu, even though Taoist Heiyu was a little helpless, he could only continue with this arrangement.

"Then the person leading the team this time...is it still Dean Yang Lie?"

Taoist Heiyu asked again.

The dean pondered for a moment: "Forget it about Yang Lie, I have other things to arrange for him. Let Zhu Yi go and retreat every day. He has been in retreat for thousands of years and has not seen him break through to the cosmic realm. It just so happens

Let him go out and relax!"

Taoist Heiyu nodded and then disappeared beside the dean.

When Taoist Heiyu disappeared, a fat figure appeared next to the dean.

"Old man, why don't you let me go?"

The dean glanced at him lightly: "You can practice your way peacefully. When you can control your desires, you can go out."

"In the prehistoric branch, I can still watch you for a little bit, but when you go out and you can't control yourself, you are killed by someone, and I am too lazy to help you collect your body!"

After listening to the dean's words, the fat figure's face became a little unnatural, and he snorted coldly: "What a joke! Will I be killed? I know the world's information, who can kill me?"

The dean looked at him calmly: "Believe it or not, I can kill you right now!"

The fat figure's face changed slightly, and after a sarcastic laugh, he stopped speaking.

"Speaking of old man, I can obviously know the world's information, but I don't know why, but it is difficult for me to capture some information from Su Yu. This guy gives me the feeling that he is covered with a layer of fog."

"It seems like it's not within the rules of the universe."

The fat figure murmured.

A ray of light shot out from the dean's eyes. He lowered his head, and there was a trace of horror in his eyes.

But soon, this look of shock was concealed by the dean.

He took a deep breath, and then said softly: "Okay, practice well. When you break through to the heavenly realm, when will you be able to enter the Ninth Academy of the Starry Sky? After you get that skill

, your shortcomings can also be made up for!"

After saying that, the dean no longer paid attention to the fat figure, but gently closed his eyes, followed by the sound of rhythmic breathing.

The fat figure glanced at the dean, smiled, and disappeared between heaven and earth.

…

"Father...does the opening of the ancient ruins require my child's intervention?"

Prehistoric Star Territory, Zi Family, Third Master's Mansion.
