This is the fifth day that Zhang Guoyong came to the primordial world. Last night, through the efforts of the Yu tribesmen, the fine stones near the nearby underground river were all picked up by them.

According to Yu Wu's report, the further you go to the left the side of the underground river, the more fine stones there are on the ground. At first, most of them were the size of eggs, but as you walked forward, fist-sized stones began to appear, and even basketball-sized stones.

Zhang Guoyong was very excited after hearing the news last night, and the smile on his face almost took up half of his face. When I slept late at night, I let out a smirk from time to time.

When he woke up this morning, Zhang Guoyong recalled the exciting events of last night. Sure enough, he guessed correctly. There is a real high probability that there is a fine stone mine deep in the mountains.

Thinking about the future, he led the Yu tribesmen to dig up the fine stone mine, and Zhang Guoyong suddenly felt his blood boiling. When the time comes, with the anti-heaven artifact of the golden finger, it will no longer be a dream to dominate the world or something. After completing a great career, he and Elena lived some amorous lives, and finally let himself and Elena's descendants open up the whole world, and he and Elena were called the ancestors of mankind by future generations. The more Zhang Guoyong thought about it, the more excited he became, and he even fantasized about Yelena saying to him, you are so powerful, you are so great. He couldn't wait for that day to come.

At this time, he found that Yelena next to him was also awake, and looked at him with a sad look.

It turned out that Zhang Guoyong was so excited, and terrible things happened in his lower body that all men understand. The most critical thing is that he moved a few times, and Yelena was woken up by him.

"Ahem. Zhang Guoyong said embarrassedly: "This is morning erection, normal boys have it." ”

You must know that Zhang Guoyong wants to show his gentlemanly demeanor in order to show himself. He has been restraining himself for the past few days, and even the frequent sex of the jerking off man is secretly done by Yelena after she falls asleep.

At this time, footsteps appeared in the distance and broke the two in a daze. Zhang Guoyong looked up and saw that it was a little girl who came over.

It turned out that the "Three Musketeers" made ceramics with stones and mud. Zhang Guoyong and Yelena urgently walked out of the cave to visit the "Three Musketeers".

The stones and mud were for the great task given to them by the "god of fire", but they did nothing. Of course, Dashan has also made a lot of contributions, but he is still confused.

The "Three Musketeers" not only made a large ceramic pot, but also completed the ceramic jar of nine. This has a 90 percent success rate. They were short of a ceramic jar that was not finished because it had cracks and was not perfect.

That big, two-person ceramic pot can cook a delicious broth. Those ceramic jars, which are only the size of two human heads, can be used as water, real things, and of course, can also be used as bowls. Against, having ceramics is really a lot of benefits.

In order to make it easy to carry, Zhang Guoyong made a grass net out of some hay, and then circled the ceramic jar in the grass net. In this way, the Yu tribesmen only need to hold the grass net and carry the ceramic jar with one hand.

The good thing is not only that, when Zhang Guoyong opened his system mall, he also found that the picture was updated.

The page is still three pages, but three new books have been added to the first page, "Introduction to China's Top Ten Peerless Beauties", "How to Effectively Find Small Movies on the Internet Not Suitable for Children to Watch", and "Spare Tire's Repair Experience".

Zhang Guoyong saw that it was all things that did not conform to the "national conditions". The second page has not changed, but on the third page two new wooden plaques have been added, "The Refining and Refining of Iron" and "How to Effectively Refine Sea Salt".

During this time, Zhang Guoyong and Yelena both felt as if they had no strength in their bodies. This is the result of the lack of salt. The blood of animals has a little salt, and the people of the Yu tribe can drink the blood of animals to replenish their physical salt needs. That's why this "How to Effectively Refine Sea Salt" wooden card is very important.

Now, Zhang Guoyong's space ring has a large amount of essence stones stored in it. Originally, he planned to use the 500 essence points absorbed by the system today for the "Gunpowder Recipe", but now for the sake of himself and Yelena's body, he decided to use the 500 essence points of the system mall for "How to Effectively Refine Sea Salt".

Thinking of this, Zhang Guoyong went to find Yu Wu and asked who in the Yu tribe was the most suitable to go to the beach.

Yu Wu called the Yu tribesmen who had been to the beach as long as they had been there. Two minutes later, sixteen people were standing in front of Zhang Guoyong. Zhang Guoyong passed the wooden plaque of "How to Effectively Refine Sea Salt" to two of them. One is the leader of the Yu tribe, the cave. The other was a tall, thin primitive man called Tree. The remaining two inheritances were given to herself and Yelena.

For the rest, Zhang Guoyong began to explain what the sixteen people were going to do, and also told the cave and the trees to teach the other fourteen how to refine salt. Salt refining is not like refining ceramics, salt refining only needs to be seen once or twice, and the Yu tribe should have learned it.

The seaside is not far from the Yu tribe. At the beginning, when Zhang Guoyong and Yelena first came to this primordial world, it took them half a day to reach the Yu tribe. At that time, they had poor physical strength, they were not familiar with the route, and a lot of things happened in the middle.

Now, the Cave Sixteen only need to walk briskly, and they can reach the beach in two hours. If they run, it will only take an hour to reach their destination. Sixteen people can also help each other outside and hunt wild beasts together.

Because the essence of the underground river near the cave is light, and the depth of the underground river is too far away, the terrain inside is unfamiliar. If you want to mine, it will cost a lot of manpower and material resources. Zhang Guoyong plans to save enough food and goods for everyone to collectively explore the depths of the underground river.

After the group of sixteen left, the rest of the Yu tribesmen followed their two "fire gods" in search of food. Yes, Yelena is also their "god of fire", and the people around the "god of fire" must also be a big man. Primitive people are always serious about what they imagine is right, they always imagine some things, and they make up a lot of things that do not exist in reality.

Their purpose was to dig up a plant that grew in the ground. This plant resembles a potato. There are a lot of potatoes in this place. Almost every dozen steps that Zhang Guoyong and the others walked, there were a large number of potatoes underground.

Potatoes are high in energy and nutrients, and they are very adaptable to the environment. When it comes to Earth, potatoes are grown in a global environment.

When Zhang Guoyong sensed the potatoes in the ground, he knew that their Yu tribe no longer had to worry about the source of food. Potatoes are also one of the best options for saving in his space ring.
