In the next few days, Gu Shi and Zhao Zhize and the other two had a great time in the Black Dog Tribe.

Seeing that the time was almost up, a few people were just thinking about packing up and going back to school for the New Year, but Gu Shi was visited by someone again.

That morning, Gu Shi was still sleeping in his room. They had played too late yesterday, so their originally planned return to school had been postponed to the afternoon.

As a result, when he was half asleep and half awake, he heard a rapid knock on the door.

“Dong-dong-dong, Gu Shi, dong-dong-dong, Gu Shi!”

The person outside was knocking on the door and calling his name. Gu Shi was woken up by the sound. He rubbed his eyes, got out of bed with resentment and opened the door.

Gu Shi opened the door while muttering, "Who is it? You come to disturb my sleep so early."

As a result, an unexpected figure stood outside the door.

"Professor Yu? Why are you here?"

Gu Shi was quite surprised. He didn't expect to meet Yu Guangyuan in the Black Dog Tribe. Shouldn't he be doing business in Congleton?

Yu Guangyuan pushed his glasses and said with some embarrassment, "I'm sorry, classmate Gu Shi, to bother you so early, but I really need your help with something. Can I come in and talk?"

"Of course, please come in."

Gu Shi made way and let Yu Guangyuan walk into his room.

Looking at Yu Guangyuan who was dressed neatly, Gu Shi glanced down at his pajamas, and then thought of his face which he had not had time to wash, he coughed softly in embarrassment.

"Well, Professor Yu, could you please wait for a moment? I'll go clean up."

"sure."

Gu Shi walked into the bathroom, quickly tidied himself up, put on a coat, and sat opposite Yu Guangyuan.

"I wonder what Professor Yu wants to see me about this time?"

Yu Guangyuan explained, "Well, I'm wondering if you have any extra Fountain of Life on hand. I'd like to buy another batch from you."

Gu Shi was a little puzzled. Logically speaking, Yu Guangyuan had bought so many Fountains of Life from him last time, so it shouldn't have been consumed so quickly.

Moreover, if the Fountain of Life had simply run out, Yu Guangyuan wouldn't have been so anxious as to run all the way to the Black Dog Tribe to find him.

Although he had many doubts in his heart, Gu Shi did not speak out. Instead, he nodded and replied, "No problem. I wonder how much Professor Yu needs this time?"

Yu Guangyuan waved his hand and said, "If possible, give me another 10 million gold coins.

However, I don’t have that much spare cash right now, so I may have to delay the payment by a few days.”

Gu Shi nodded. "Okay, Professor Yu, do you want it now?"

"Yes, the sooner the better. I've already prepared the container. I'll leave the rest to you."

As he spoke, Yu Guangyuan took out a cylindrical bucket from his space ring. In order to facilitate measurement, he even had scales marked on it.

After putting the bucket on the ground, Yu Guangyuan took the initiative to leave the room and let Gu Shi do the operation alone.

Ten million Fountains of Life sound like a lot, but in reality it is not that much. Gu Shi took out the Ancient Silver Spring Heart and quickly filled the bucket.

Gu Shi opened the door and said to Yu Guangyuan who was standing outside, "Professor Yu, the things are ready. Come in and get them."

Yu Guangyuan walked into the room, closed the lid of the bucket, and took away the fountain of life.

Before leaving, he specifically said to Gu Shi, "I'm not sure if these Fountains of Life are enough. I might need to trouble you again later. Can you stay in the hotel for today?"

Gu Shi replied, "I'm going back to school today. Professor Yu, if you still want to see me, you can contact me directly through Explorer and we can meet at school.

That way, you don’t have to make a special trip here.”

Yu Guangyuan shook his head. "No, it's more convenient to trade here. If it's nothing important, can you go back a day later?"

"Is that so? I understand. I'll stay here today."

Gu Shi was a little surprised. Would it be more convenient to stay here? Could it be that the people who really needed the Fountain of Life were from the Black Dog Tribe?

Although he was somewhat curious about the reason behind this, he did not ask any further questions and just agreed silently.

Yu Guangyuan left, but Gu Shi was no longer sleepy after all this trouble, so he simply went downstairs to have breakfast.

By the afternoon, Cheng Xuqing and the other two also got up one after another.

When they heard Gu Shi say that he had something urgent to do and could not go back until tomorrow, the three of them were very surprised. After all, they had already agreed to go back together today.

Gu Shi did not explain the whole thing to them very clearly, but just vaguely said that there might be another business to do later.

Anyway, Gu Shi was only going to go back a day late, it wasn't like they wouldn't see each other anymore. Cheng Xuqing and the other two didn't delve into his excuse. After understanding the situation a little, the three of them went back first.

Now, Gu Shi was the only one left in the hotel.

Gu Shi sat by the window, looked up at the setting sun, and muttered to himself, "Hasn't it come yet? It seems that it's enough."

Seeing that it was getting late, Gu Shi stood up, stretched, and prepared to go downstairs for dinner.

Who knew that as soon as he opened the door, he ran into Yu Guangyuan who had just raised his hand and was about to knock on the door.

Seeing Gu Shi push the door open, Yu Guangyuan put his hand down and said with a smile, "What a coincidence! Are you going downstairs to eat? How about we talk while we eat?"

Gu Shi rejected Yu Guangyuan's suggestion, "No, I'm not that hungry yet, I just think it's almost time, come in."

The two sat down face to face again.

Gu Shi was the first to ask, "Isn't the amount of Fountain of Life that Professor Yu took away this morning enough?"

Yu Guangyuan sighed, "Yes, and it seems that a large quantity will be needed later. Do you have much stock on hand? Let me be mentally prepared first."

Gu Shi smiled. He was not worried about the quantity of the Fountain of Life. Gu Yinquan had a lot of stock in his mind. Even if this amount was used every day, it would last for a very long time.

Gu Shi comforted him, "Don't worry, Professor Yu, the Fountain of Life is definitely enough. You just need to tell me how much more you need."

Hearing what Gu Shi said, the sadness on Yu Guangyuan's face disappeared.

"Really? That's good."

Then he lowered his head and thought for a while. After considering it for a while in his mind, he spoke again.

"In that case, I won't continue to be the middleman. Tomorrow I will introduce you to the High Priest of the Black Dog Tribe, and you can negotiate the subsequent transactions directly with him.

The High Priest is in urgent need of the Fountain of Life. If you can satisfy his needs, you will definitely be able to obtain many precious treasures from him."
