At this moment, a male Yu tribesman who was standing outside the circle rushed out and directly knocked down one of the female Yu tribesmen who was dancing. Then the question of the origin of mankind begins.

Suddenly, the crowd began to boil, and everyone kept jumping and cheering. Zhang Guoyong and Yelena were stunned by this sudden phenomenon. Khan, it turns out that what Yu Wu said about making the Yu tribe stronger meant this.

Seeing this, the female Yu tribesmen who were not knocked down danced even harder. The scene that followed was also predictable, only to see one male animal after another, all with red eyes, panting and running to the center of the human circle.

Elena's face was already red and about to drip blood. Although the distance was a bit far away and the light was a little dim, this did not affect Zhang Guoyong's interest in the slightest. Now he only hates that he was born short, and the Yubu people always block his vision.

Just when Zhang Guoyong's neck stretched out like a giraffe, his hand was pulled. Hey, my future daughter-in-law is here, and I can't put on the same face as a pig brother when I was on the earth before.

A pleasant day passed like this, go to bed when it gets dark, Zhang Guoyong has always followed his mother's teachings, sleeping more is good for his health, and he will not waste time sleeping with Yelena in his arms.

Today's night is destined to be unpeaceful, and the picture of the fornication of the Yu tribe has been engraved in the minds of Yelena and Zhang Guoyong. When the Yu tribesmen will end this activity, Zhang Guoyong doesn't know, he only knows that he slept comfortably tonight and had a pleasant dream.

This is the fourth day that Zhang Guoyong has come to this reason world, and when he woke up, he found that Yelena next to him had woken up early.

Elena was embarrassed at this point because she had noticed her panties wet this morning. Zhang Guoyong didn't notice this, he hugged Yelena gently, and said with a smile: "Honey, do you know, I slept so comfortably last night, I really want to hold you like this all the time, I really want time to stop at this moment......"

The more Zhang Guoyong spoke, the more moved he became. He felt that Yelena would burst into tears when she heard his love words.

Yelena gently put her hand on Zhang Guoyong's chest, since Zhang Guoyong's body was strengthened by the system, to put it bluntly, he was already a man with four-pack abs.

"I'm here for my aunt today. Yelena said softly. Ah, Zhang Guoyong almost forgot that girls still have this physiological phenomenon. He only remembered that when the girl's aunt came, some people would be in pain, and some would be fine. He still remembers that when girls come to their aunts, they need to drink more hot water.

He took the "Wilderness Survival Guide" from his pants pocket, and he didn't put his hope on this "Wilderness Survival Guide". When he turned the page of this "Wilderness Survival Guide", he was very surprised to find that this page was written about what to pay attention to when the girl's aunt came.

Zhang Guoyong was taken aback, he remembered that this book should not have been written because he had already finished reading this "Wilderness Survival Guide". If he's not guessing wrong, what knowledge he's looking for, the book will automatically show you what you're looking for.

Yelena didn't actually come to the big aunt, she just wanted an excuse to wash her panties.

This "Wilderness Survival Guide" writes a lot of things that aunts should pay attention to. If you do a good job of hygiene, you should wash your vulva every day, and use one pot for each person. Underwear should be changed and washed frequently, sterilized by boiling water, and the quality of sanitary napkins should be good.

Also, eat more fruits during menstruation, but benign, such as: watermelon. Fruits should be eaten at room temperature, frozen in the refrigerator, forget it. Eating frozen food for a long time will cause cold in the uterus and affect fertility. You can eat some chocolate brown sugar water, don't eat sour and spicy food, eat a light diet, try not to touch cold water, and wash clothes.

Fruit is there, but brown sugar water is not. Zhang Guoyong immediately volunteered to help Yelena wash her underwear. A man washes a girl's underwear or something, Zhang Guoyong is happy to help Yelena. As for washing her underwear, Yelena has no resistance.

Just do it, Yelena took off her underwear in front of Zhang Guoyong and handed it to Zhang Guoyong. Anyway, I wear a short skirt, *** is very convenient, and I don't need to take off a short skirt.

So, Elena and Zhang Guoyong went to find Yu Wu and asked Yu Wu to take them to the depths of the cave to fetch water. Zhang Guoyong and Yelena had never been there before, and this was the first time they had gone to the underground water deep in the cave, and it was usually the Yu tribesmen who used leaves to fill water for him.

The light at the entrance of the cave was extremely dim, and if they didn't take them there, they wouldn't dare to go deeper into the hole, and no one was afraid that they would fall down as they walked. Yu Wu raised his torch and led the way.

Elena found that the deeper she went, the colder it became. In addition, she is now slippery underneath, and she is very uncomfortable.

At this moment, a gentle breeze blew through. Yelena was feeling the coolness beneath her when her short black skirt was blown up by the wind. Suddenly, Yelena let out an "ah", and hurriedly pressed the short black skirt that was floating upward.

Zhang Guoyong and Yuwu were startled by her "ah". "It's okay, it's okay. Elena hurriedly waved her hand in response.

Suddenly, a golden light appeared in Zhang Guoyong's eyes. At this time, he remembered that the system had not yet given him a newbie sign-in package for the third day.

Just as he raised his right index finger, he noticed that the golden light was not coming from his right index finger. At this moment, he noticed that the golden light was coming from the cleavage on Yelena's chest.

I'll go, why is this little mud's cleavage so dazzling, so charming, is this the legendary two-dimensional cleavage?

Yelena was pleasantly surprised and said to Zhang Guoyong: "I have found the existence of the essence stone on the Prophetic Disk, and it is about 100 meters away from us. ”

Zhang Guoyong was overjoyed when he heard it, the essence stone is a precious item needed by the system, with the essence stone, the system can have energy to operate, and it depends on the system for himself and Yelena to gain a foothold in the primitive world. So, he hurriedly urged everyone to speed up. Yuwu was strange, she went to fetch water every day, but she had never heard of a spirit stone again.

Soon, the group of them came to the underground river. Following in the footsteps of Yelena, Zhang Guoyong finally found the essence stone that the system coveted on the ground, and obtained two pieces.

These two fine stones were about the size of a fist, and they were quite heavy when they arrived. When Zhang Guoyong's right index finger touched it for two or three seconds, Zhang Guoyong's right index finger emitted a faint golden light, and emitted golden data chains to surround the essence stones in his hand.

After dozens of seconds, under the shocked gaze of Yu Wu next to him, the two fine stones disappeared as if they had merged into the golden data chain. Zhang Guoyong did not explain the real reason to Yu Wu, anyway, it is difficult for Yu Wu to understand the world as a modern person. Zhang Guoyong attributed all phenomena to the "god of fire" they believed in.
