In a blink of an eye, more than a month has passed.

Under the separate guidance of the old supreme, Su Yang learned and learned in detail the two courses of "Geography" and "Malignant Biology" in the Source Realm with his intelligence and powerful memory.

Don’t underestimate the two courses of “Geography” and “A Collection of Malignant Biology”. According to the description of the Old Supreme, these are the results of countless practitioners in the holy realm who have been exploring one after another over the past tens of billions of years.

Although these achievements only cover the area of ​​the 300,000-mile radius of the source realm, over tens of billions of years, the holy realm practitioners who died in the exploration process are no longer counted.

Not to mention anything else, during the guidance period, the old supreme invited Su Yang to see the Yingling Mountain in the Holy Realm.

This Yingling Mountain is towering into the clouds. Tens of millions of heroic spirit monuments are towering on the entire mountain. Each of the heroic spirit monuments has at least tens of thousands of names carved on it. All of them are dead holy practitioners in the process of exploring the source world. There are Dharma Lords, Supreme Lords, and Taoist Lords. Almost everyone represents a heroic story.

Looking at the heroic monuments, even if Su Yang did not like the style of the three masters and the noble attitude of the Holy Realm, he had to admit that the Holy Realm had indeed made many sacrifices in order to protect the gate of the Three Thousand Realms of the Great Heavenly Dao.

Therefore, when the old supreme taught Su Yang the two courses of "Geography" and "Malignant Biology Collection", Su Yang studied with a serious mood without any intention of burnout.

In this regard, the old supreme also expressed recognition of Su Yang's attitude, and at least the look of looking at Su Yang was less disgusted.

In this way, Su Yang and the old supreme master learned and taught each other, and more than a month passed very fulfillingly.

When the old supreme finally passed on the knowledge he knew to Su Yang, he waved his hand, put away the textbook, and said lightly: "The knowledge that should be taught has been taught to you. Someone will come to find you later and take you to the next exploration team to go on the expedition, where you can learn the necessary knowledge of survival in the source world."

After saying that, the old supreme no longer looked at Su Yang, got up and prepared to leave.

"Sir, stay!" Seeing that the old supreme was about to leave, Su Yang quickly stepped forward, and took out a jade box with cold air rising from his sleeve and sent it to the old supreme, saying, "Sir, I have no way to repay me for so many precious and important knowledge. I am very careful. Please accept it with a smile. Maybe it will play a role in your injury."

The old supreme eyes dimmed for a moment, stared at Su Yang and asked, "Who did you know that I was injured?"

Su Yang smiled and said, "Sir, I'm thinking too much. I still have this little bit of vision. Otherwise, how could my original lifestyle attract the attention of the three masters?"

The old supreme thought for a moment, but finally shook his head and said, "I have received my heart. You should take it back. My injury is a stubborn disease. Many experts in medicine have seen it, but it cannot be cured."

Su Yang had no intention of taking back the things and said with a smile: "I believe that my achievements in alchemy are a little capable. So, sir might as well see if the pill in my hand can suppress the evil fire in my body."

The old supreme narrowed his eyes slightly. Although he spent more than a month with Su Yang, he was just imparting some knowledge. There was no physical contact between the two parties. How did Su Yang diagnose the stubborn disease in the old supreme?

That's right, as Su Yang described, there was a vicious fire in the body of the old supreme. This was a special substance formed after the malignant substance was confused with a certain fire force, and it was not so easy to resolve.

Therefore, if the old supreme had not practiced deeply enough in Han Bing, he could not suppress the evil fire in his body.

But it was just suppressing, very reluctant. Almost all of its own power was suppressing this evil fire. If there was a slight slack, it would be counterattacked by the evil fire and burned to ashes.

Therefore, based on this situation, the old supreme cannot even exert one percent of his own cultivation in daily life. He can only do some very simple magic, and even cannot fight with others, otherwise he will be doomed.

Otherwise, the old supreme would not have fallen here to teach and impart knowledge of the source world. He would continue to explore the source world, kill countless vicious creatures, and avenge those companions back then.

It can be said that if the old supreme was not very clear in his heart, it was also very important to impart knowledge from the source world, which could greatly increase the chances of many new and young people who had just achieved success in their cultivation. The old supreme would have been unable to withstand it anymore and would rather burn himself to ashes than live like this, and would have no face to face his companions who had sacrificed that year.

"Oh~!" After sighing, the old supreme hesitated for a while, he did not let Su Yang down. He accepted the jade box with cold smoke rising and slowly opened it in front of him.

Inside the jade box, there was a white pill the size of a thumb, with a stream of cold smoke and fragrance rising all over the body, which looked very extraordinary.

"Huh?" Seeing this white pill, the old supreme exclaimed lightly on the spot. He was surprised to find that the jade box itself was not a substance like cold jade. The reason why the tentacles were cold is because of this white pill.

More importantly, although this white pill was chilly, it was not domineering at all. Instead, after smelling the fragrance emitted from it, the old supreme immediately felt a cool feeling penetrated into his heart, as if in the dry and hot desert, he took a sip of iced watermelon juice, not to mention how comfortable it was.

Awesome, just a pill, it actually has such a miraculous effect!

The old supreme was indeed shocked this time. He had to look at the white pill given to him by Su Yang and began to carefully identify it.

But if you don’t recognize this, you will be even more shocked when you look closely!

As the saying goes, if you become a doctor after a long illness, the old supreme has tried many ways to treat the malignant fire poison in his body. He naturally tried many methods and searched for many rare medicinal materials.

So as time goes by, the old supreme dare not say that he is familiar with various pharmacology, but he has really learned a lot of ways to identify medicinal materials.

It is precisely because the old supreme master also understands these that he was able to judge that the materials used in the white pill refined by Su Yang are not complicated, and many of them are even ordinary medicines.

But these ordinary medicinal materials are so extraordinary after being fused together.

For a moment, the old supreme remembered some things that he once said: Alchemy can be divided into three stages. The first stage is to flexibly use the medicinal properties of various heavenly and earth treasures; the second stage is how to flexibly match the medicinal properties of various heavenly and earth treasures; as for the third stage, it only exists in legends, and it is better not to say it.

At that time, the old supreme said jokingly: It's boring to say half of the words.

But now because of a pill, the old supreme ruled Su Yang completely and took it seriously. He even changed his name and called him a friend to show respect.

Su Yang didn't care about this, but after his mind moved slightly, he bowed and said, "Sir, I'm not too late to thank me, so I naturally wouldn't care about this little thing."

The old supreme nodded slightly and said with a smile: "It's so good, then wait until you stabilize in the exploration team, and I will come to visit with my close friends. As for now, I will say goodbye first."

Su Yang replied: "Sir, please give me a gift!"

The old supreme didn't say a word, and this time he turned around and left without looking back. However, when he just walked to the door, someone happened to come in. The two sides met slightly and nodded at each other. Then he saw the old supreme salute. After the other party returned the salute, he often passed by.

Then, the person who came in was filled with amazing evil spirits. He smiled and said to Su Yang with a graceful smile: "Prepare and follow me to explore the team!"
