Zhang Yu nodded slightly, put away the spirit stone, and then gave Chen Gu the key to the sky realm.

Holding the key to the Sky Realm in his hand, Chen Gu was extremely weak, but there was a satisfied smile on his face. He paid such a great price and even betrayed his own essence and blood to get a key to the Sky Realm. It was worth it!

Seeing this, Ao Kun was ready to speak. However, before he could speak, Zhang Yu understood his intention and immediately asked with a smile: "You must also exchange for the key to the Sky Realm, right?" As soon as he thought, a key to the Sky Realm appeared in front of him, and it flew towards Ao Kun automatically.

Ao Kun took the key to the Sky Realm and presented all 150 spirit stones.

After Zhang Yu received the spirit stone, Ao Kun retracted his gaze and stared at the jade plaque with the words "Key of the Sky Realm" in his hand. His expression was quite complicated. He didn't know whether it was worth it to pay such a great price for the key of the Sky Realm. He only knew that even if time went back and everything started over, he would still make such a decision.

"For you, I gave up my pride as the dragon clan Taixu True Dragon and betrayed my own essence and blood. I hope you don't let me down!" Ao Kun stared at the jade tablet and murmured in his heart.

Now, Chen Gu and Ao Kun, the two richest people in the world, were completely exhausted by Zhang Yu!

The treasures they had collected for countless years were not left, and even their essence and blood were squeezed out by the Cangqiu Academy... At this time, they probably couldn't even take out a little valuable thing on their bodies, and it was not much better than the beggars on the street.

Zhang Yu was very satisfied with this result. Seeing that Ao Kun could not squeeze out anything valuable from Chen Gu, he couldn't help but turn to look at the formation Saint Luo Xuyang, the Dan Saint Cui Jian, the craftsman Hongjin Castle and the book Saint Yang Pei'an, and smiled and said, "Do you want to consider exchanging something?" After squeezing Chen Gu and Ao Kun, he changed his target to the four formation Saints.

It seems that his purpose is to squeeze out the richest group of people in the world and bring all the good things to Cangqiong Academy.

For some reason, although Zhang Yu was smiling at the four people of the Formation Saint, the four people of the Formation Saint felt like they were being targeted by the demon. They always felt that the smile was not good.

The four of the Array Saint couldn't help but tremble, and their hairs stood upside down.

"By the way, I almost forgot to update the redemption list." Before the four men of the Array Saint spoke, Zhang Yu seemed to suddenly remember something. With a wave of his hand, the picture projected in the sky changed suddenly. The originally slightly simple redemption list added many new products, most of which were treasures that Chen Gu and Ao Kun had just contributed, and some were super beast essence and blood.

The key to the Sky Realm, the low-level divine nature, the heaven and earth creation pill and other objects, the information has not changed.

But at the bottom of the song of life, there are many more exciting products.

Blood Fruit: Eight Spirit Stones (can greatly purify bloodlines or evolve bloodlines. The best effect is for the demons and dragons. Human practitioners take it, and the effect is minimal)

Protecting dragon scales: four spirit stones (the hardest dragon scales on the strongest dragon clan can be used as auxiliary materials for refining artifacts, containing powerful dragon power. The weapons refined with it have suppression, deterrence effect on monsters that are not super divine beast bloodlines, and increase lethality by 50%)

Boneless Spirit Fetus: Three Spirit Stones (can greatly improve the cultivation talent, reshape the root bones, and take it with the Blood Fruit, the best effect. If taken alone, the effect is less than half of the Song of Life)

Tears of the Deep Sea: Three Spirit Stones (similar to the protective dragon scales, have a deterrent effect on the monsters in the sea. The weapons refined with it increase the lethality of the monsters in the sea)

Seventh-generation lotus: A spirit stone (can be used as the main material of the pseudo-divine pill "Soul Pill" or can be taken directly, greatly increasing the soul power and increasing the intensity and range of thoughts)

Zi Yanhua: A Spiritual Stone

Flame mud: a spirit stone

Citroen: A Spirit Stone

Three-pointed Barblade: A Spirit Stone (Ordinary Sixth-grade Weapon)

After these products, there are various super beast essence and blood.

Greedy Wolf Dog's Essence and Blood: A Spirit Stone/Drip

The essence and blood of the Heaven-Swallowing Beast: a spirit stone/drop

The Demon Bull King's Essence and Blood: A Spirit Stone/Drip

It was not until the end of the essence and blood product that the essence and blood of Chen Gu and Ao Kun appeared.

Moon-eating Heavenly Wolf (provided by Chen Gu): a spirit stone/drop

Taixu True Dragon (provided by Ao Kun): A Spirit Stone/Drip

Seeing his essence and blood being put on the shelves as goods, and each drop is worth a spirit stone, Chen Gu, Ao Kun's mouth twitched slightly, and he didn't know whether to be proud or smile bitterly.

What made them quite helpless was that the dean not only placed their essence and blood on the shelves, but also clearly marked their names, as if afraid that others would not know that the essence and blood came from both of them.

Looking at the new redemption list, Zhang Yu was quite satisfied and couldn't help but nod: "It's not bad, now there are a lot more types of products, and there is even more room for choice."

I have to say that Chen Gu and Ao Kun have collected a lot of good things over the years. Although they are not very attractive to Zhang Yu, they are still very attractive to ordinary people, especially the "Seven-generation Lotus" provided by Chen Gu. Even Zhang Yu, a powerful man in the transcendent realm, is a little moved, greatly increasing his soul power. This effect is very rare. What's more, the "Seven-leaf Lotus" can also serve as the main material of the "Soul Pill" and can be refined into the "Soul Pill" with other materials.

The creation pill of heaven and earth, the soul pill, and the immortal pill. These three pills are the three top pills in the history of the wilderness small world. Each one is called a pseudo-divine pill. It has the magical effect of seizing the creation of heaven and earth, making countless strong people flock to it, and even triggering bloody battles after blood.

The three top elixirs, refined into any of them, mark a peak of a six-star alchemist!

The Heaven and Earth Creation Pill reshapes the root bones, greatly improves talent, and can reach the limit of six stars.

The soul pill is restored and strengthens the soul power. There are even rumors that even after taking the soul pill, even after falling and reincarnation, you can still awaken the memories of your previous life. Although the rumors are not necessarily true, the effect of enhancing the soul power is not enough even if you take 10,000 soul-raising pills.

The immortal pill is said to have the miraculous effect of life and death, human flesh and bones. Even if the peak-level strong man is abolished and seriously injured and sleeping, he can still save him and restore his cultivation to his peak period.

The heaven and earth creation pill and the immortal pill are of no use to Zhang Yu. He does not need talent. He can heal the ability. He can condense a wood element spirit ball at will, and the effect is no less than that of the immortal pill. Only the soul pill has a great effect even for Zhang Yu who is transcendent.

He was even thinking in his mind whether to remove the Seventh-generation Lotus from the Shelves and refine them into the Soul Pill to taste the taste.

But after thinking about it, he still didn't do this. He is the dean of Cangqiong Academy, why should he compete with a group of tutors and students for profit?

"Look at it, maybe there are products that you are satisfied with." Zhang Yu's eyes fell on the four Array Saints again and bewitched: "Personal opinion, you might as well exchange it quickly. It's too late, maybe all good things have been exchanged by others. For example, Dan Saint, you can exchange top alchemy materials such as Zi Yanhua, and Craft Saint can exchange top weapon refining materials such as flame mud. Array Saint can exchange gold obsidian, wood obsidian, etc. for setting up a formation. The effect is definitely much stronger than the protection array of your Formation Master Guild. As for Book Saint, you can exchange seven-generation lotus to enhance soul power, enhance thoughts, memory, thinking reactions, etc., with many benefits."

Looking at Zhang Yu's smiling look, the faces of the four men of the Array Saint froze slightly, and they felt a chill inexplicably.

They felt that Zhang Yu was thinking about them on the surface, but in fact, he seemed to be eyeing the treasures they had collected over the years.

It seems that if they didn't exchange these treasures for spirit stones, they would probably not be able to get out of the Sky Academy today.

"That..." The formation of Sheng Luo Xuyang looked at Zhang Yu carefully and said with a thorn in his mouth: "If we don't exchange these things, will we not be able to obtain the key to the Sky Realm?"
