With this doubt, Houyi followed Chang'e into a small wooden house. The decorations in the house were quite ordinary, and they were all common things in daily life.

"Ahem, is Xiao E back?" At this time, a cough came from the inner room, and then asked in a weak voice.

"Yes, father, I'm back." Hearing this, Chang'e quickly turned into two steps and walked into the inner room.

Houyi followed him and didn't go in. After all, it was someone else's bedroom. If he went in without permission, he would seem rude.

Houyi was listening to Chang'e chattering inside, basically Houyi saved her, and now he is taking him back to treat you, etc.

This made Houyi blush outside. To be honest, he was still in the guilt of putting Chang'e in danger. Now Chang'e is praising him inside, how can he not blush?

"Brother Houyi, come in." Just as Houyi was thinking about it, Chang'e's voice came.

Houyi came to his senses, took a breath and walked in. At first glance, Houyi saw the skinny old man on the bed. The old man was already very old, his hair and beard were all white, and he was lying on the wooden bed with a weak face.

"Old sir." Houyi bowed, saying hello.

"Ahem, benefactor, you are polite. I can't get up and thank you for your life-saving grace to my Xiao E." The old man said intermittently and intermittently.

"The old man is serious, I'm just a simple task. Let me see what kind of disease the old man is suffering from." Houyi smiled and said.

After saying that, Houyi took a step forward and put his hand on the old man's body. Then a stream of energy penetrated into the old man's body along his hand.

"Hmm? The demonic energy entered the body?" Houyi was shocked when his energy entered the old man's body. How could the old man be eroded into this shape by the demonic energy?

"Her sir, have you met some evil creature recently?" Houyi was very familiar with the demonic aura. After all, the witch clan and the demon clan are mortal enemies. If he can't even see this, it would be a waste of time.

Chang'e next to her was shocked when she heard Houyi's question. Although she knew that the old man was sick, she had not helped the old man check it. So Houyi now found out that the old man was being penetrated by demonic energy, which made her heart beat. You must know that she is the demon clan.

Although she has treasures to hide her identity, this cannot change the fact that she is a demon clan.

And there was another thing she was very confused. When she took the entire village into her body, the old man had no evil spirits into his body, but he was just sick.

"A evil thing? No, I have never met it before." The old man denied without hesitation. He was sick in bed and did not go out of the door, so how could he meet an evil thing?

"That's strange." Houyi thought with thought, how could he accumulate so much demonic energy in his body without meeting a demonic creature?

"How about Brother Houyi, can my father's illness be cured?" Chang'e next to him saw Houyi thinking, and quickly interrupted him. You know, it is very dangerous to think like this. After all, she, a human counterfeit, can't stand the consideration.

Moreover, she had already thought about how the demonic energy in the old man's body came from. It should be that she had taken all the people in the village into the space inside, so the old man was eroded by the demonic energy in the space inside her body.

"Oh, it can be cured. As long as you remove the demonic energy and take some spiritual medicine to replenish blood energy, the old man can go to the ground soon." Houyi was interrupted by Chang'e and came back to his senses.

"Really, that's great, thank you Brother Houyi." Chang'e said with a look of surprise.

"It's okay, it's just a small task. I'll remove the evil spirit for the old man now." Houyi smiled. For some reason, he enjoyed the feeling he is now.

After Houyi finished speaking, a powerful energy surged into the old man's body. While protecting the old man's fragile body, he drove out the demonic energy in his body. Although there were many demonic energy, how could he resist Houyi's actions? In a short while, it was cleared away.

"Old sir, try to move now." Houyi then took back the hand that was on the old man and said with a smile.

"Hmm?" The old man opened his eyes when he heard this. A warm current came from Houyi's hand just now, which made him feel so comfortable that he almost fell asleep. Now that he heard Houyi say this, he quickly tried to move his hands and feet. Suddenly, he felt that his hands and feet were much relaxed and he got up in one fell swoop. This made him overjoyed and thanked him repeatedly: "Thank you, thank you, thank you."

"You don't have to be polite, sir." Houyi felt that today was the most thanks he had received in his life.

"Xiao E, go and prepare the meal. Today we will thank our benefactor." The old man was happy and immediately remembered to entertain Houyi.

Houyi didn't refuse either. He was originally a little impure, so it would be better to stay a little longer.

Chang'e next to her was also an impure-minded person. When she saw Houyi not refuse, she stood up and went to prepare the meal.

The meal was so happy. Except for the old man who was not clear about it, the other two were all different.

Afterwards, it was getting late and Houyi had no reason to stay, so he had to say goodbye for the time being.

Of course, both Houyi and Chang'e knew in their hearts that this was just a temporary farewell and that the days they wanted to see each other will definitely not be missing.

And the fact is the case. In the days to come, Houyi came to this small tribe on time every day to help the Chang'e family do some housework.

The result of two people with different minds and different purposes in their arms can be imagined.

However, Tang Feng, as the saint of human race, was not clear about these things.

After nearly a hundred years of development and the guidance of Tang Feng, the human race has been much faster than the exploring and moving forward on its own. The population has already increased dozens of times, and its territory has expanded a lot. He naturally has no time to pay attention to the matter of a small village.

Moreover, the exchange will start its first trade in the prehistoric world in the near future, and Tang Feng has no time to pay attention to human affairs. Even the prehistoric things, he rarely pays attention to them.

During this period, Tang Feng has been in the human base camp, staying in his doorstep all day long, and making every effort to prepare for the upcoming exchange matters.

Fortunately, there are many treasures that have been blackmailed from the demon clan, so I think there is no problem in dealing with this first transaction.

It can be said that this exchange trade is the one that Tang Feng attaches most importance to since so many times.

After all, he plans to stay in this prehistoric world for countless years, and this first time is particularly important.

It is difficult to speak out. As long as this is the first time he has done it, he will not have to worry so much in the future.
