On the afternoon of the same day (July 18), after breaking up with the alien deputy stationmaster at the entrance of the hotel, the deputy minister of the Ministry of State Security took his bodyguard and returned to the capital of China directly by plane.

Li Xin and Xu Ran escorted the 'weird mobile phone' and the four experts from the National Security Bureau to the laboratory that did not have time to do the test in the morning and continue to test the mobile phone.

The results of the afternoon test were also not optimistic, and no clear conclusions could be drawn; It can only be said that the current detection methods have not been able to reveal the secrets of the 'weird mobile phone'.

Subsequently, the 'weird mobile phone' was still stored in the building of the State Security Bureau of S City, waiting for the experts to do further research, and the two experts from the Ministry of State Security returned to the capital by civil aviation plane the next morning.

Li Xin, Xu Ran and four others returned to Zhongzhou City by plane on the morning of July 19.

As for the deputy stationmaster of the aliens, he took a flight from S City to New City on the evening of July 18 and left Huaxia; The field staff of the National Security Bureau in S City watched the deputy stationmaster board the plane and leave S City; Of course, the sighting here is a completely covert operation.

On July 18th, Xu Ran's personal information value displayed in the 'Dream Game' has been changed to: Mental Force Field: 43, Mental Power: 150, Stamina: 25, Field Energy: 430.

When the **** of July 19 entered the 'mandatory task' again, his order in the defensive queue had already been adjusted from the second row to the third row.

When Kong Xiuying reached 30 on July 12th, Xu Ran taught her the basic exercises of 'Spiritual Power Imperial Envoy Two Things to Do Different Exercises' through the method of 'skill copying' at the sheep herding base, Kong Xiuying was rewarded with 'Five-Star Silver Star Honor Value' by the system after practicing this exercise on July 14, and then Kong Xiuying shared the skill with the 'Skill Hall' and won the 'Five-Star Silver Star Honor Value'.

So far, Kong Xiuying's cumulative honor value is: 'two-star gold star' honor value + 'two-star silver star' honor value.

Xu Ran entered the 'Dream Game' on the afternoon of July 15th, entered the 'Mental Force Field Space', randomly found a task scene, and showed the role of the 'Mental Power Shield' to the 'Dream Game' system, his current 'Mental Power Shield' already has a considerable ability to resist blows, and was immediately discovered and recognized by the game system, and was rewarded with the reward of 'Eight-Star Venus Honor Value', which is also higher than the usual skill reward, which shows the degree of recognition of this skill by the game system.

When he entered the 'Dream Game' again on the night of July 15th, Xu Ran received an invitation to the 'Skill Hall', hoping that he would share this skill, this time Xu Ran did not hesitate, and immediately went to the Skill Pavilion to share this skill, and at the same time received the 'Eight-Star Gold Star Honor Value' reward of the 'Skill Hall' reward, as well as the promise of half of the future merit income.

The reason why Xu Ran didn't leave it to copy to Kong Xiuying this time was that considering that Kong Xiuying needed a certain amount of time to train into a 'spiritual power shield' with a certain strength, and in this quite long period of time, the players of the 'Interstellar Confederation' who entered the 'compulsory mission' were bound to have seen and mastered this skill. Honor Reward'.

As of July 15, Xu Ran's cumulative honor value is: "'four-star gold star' + 'three-star silver star' + 'six-star bronze star'".

Starting from July 15, Xu Ran's maximum allowable stay in 'True Love and Real Scenes' has been changed from 10 days to 12 days.

During the period from July 5th to July 19th in the real world, Xu Ran had spent another 146 days in the 'Flood Wilderness' world, and the children born to Xu Ran by 'Qingfeng' and 'Mingyue' were all 7 months old.

During this time, in order to create more safe space for the primitive tribes, Xu Ran organized the primitive people to start a large project, and the amount of work of this large project was really not small compared to the limited primitive people.

The purpose of this project was to enclose the valley passage into the primitives, which was about 150 meters long, with an average width of 18 meters, 20 meters at the widest point, and 10 meters wide at the narrowest point; The part of the valley bordering the camp inhabited by primitive tribes has a difference of more than 8 meters.

Xu Ran's plan was to build a retaining wall (equivalent to a city wall) at the entrance to the valley, and use the cliffs on both sides of the valley as a barrier to make the valley a safe enclosed space; For now, it can prevent predators from entering the valley, and in the long run, even if an enemy attacks the primitive tribes, the retaining wall that closes the valley will be a natural barrier.

The retaining wall planned by Xu Ran is 8 meters high, 9 meters wide at the bottom, and 8 meters wide at the top. There is a staircase leading from the valley to the top of the retaining wall, and the way to enter and exit the valley is to install two special rollers on the side of the top of the retaining wall facing the outside of the valley, which are used to lift or drop two hanging baskets, through which people or goods can enter and exit the valley.

This way of entering and exiting the valley is similar to the way primitive people went up and down to live in the past, except that Xu Ran applied this method to the entrance of the valley, which is 15 meters wide; In this way, Xu Ran created a usable safe area of more than 3,000 square meters for the primitive tribe; At the same time, it also added another line of security to the camp of the primitive tribes; The way that Xu Ran designed for them to use the roller to cooperate with the hanging basket and load and load the goods can effectively save manpower and improve labor productivity; This way of matching the wheel with the hanging basket was also used on the high ground inhabited by primitive people, for primitive people to enter and exit the highlands.

Because of the planned retaining wall, Xu Ran commanded the people of the primitive tribe to build a relatively large copper-smelting furnace in the valley, so that the ore mined by the primitive people only needs to be piled up next to the copper-smelting furnace in the valley, which can reduce the distance of ore transportation and save the cost of ore transportation; When the blister copper is refined in the valley, it is transported to the furnace on the high ground for refining; With these two copper smelting furnaces, the efficiency of copper smelting has also increased.

The vacant land in the new circle in the valley can also be used to pile soil for agricultural planting, although the land area of this new circle is not very large, but the labor cost of the enclosure is not very high; And if you want to enclose the land by building a large area of masonry walls outside the valley, it is far from being able to accomplish this number of primitive people in a short period of time; As for whether to expand the area of enclosure in the future, it will have to be decided by the primitive people after the population base increases.

The retaining wall designed by Xu Ran for them is made of 1-meter-thick brick masonry on both sides of the inner and outer sides, and between the brick masonry on both sides, four one-meter-thick brick walls are built horizontally and at equal distances to fix and tie knots; The tic-tac-toe space created by these brick walls is made up of waste slag left over from copper smelting, weathered rock fragments, and a mixture of fine soil.

The mixture is configured according to this proportion, mixed with a certain amount of moisture, and then filled into the tic-tac-toe gap formed by the brick wall in layers, and tamped with wood, its texture is very dense and firmly combined.

The masonry slurry of the brick wall is also mixed with a mixture of these three materials, but the waste slag and weathered rock used are all specially selected fine crushed materials that are close to powder.

As of July 19 in the real world, the retaining wall has been masonry 6 meters high.

In terms of production tools, Xu Ran also introduced the model of the wheelbarrow for the primitive tribe, which is a wooden structure except for the bronze parts used in the axle, and the safe weight it can carry is about 100 catties; However, it still has an obvious effect on improving transportation efficiency, especially because it introduced the concept of vehicles for primitive people, and it can be regarded as instilling a new concept for primitive people, even if Xu Ran did not have the opportunity to enter the primitive tribe in the future, the people of the primitive tribe also have the imagination space to develop vehicles independently.

In terms of weapons, Xu Ran introduced the bow and arrow for them, the bow of the bow and arrow, Xu Ran is a tree species with smooth branches, straight branches, few scars, and good toughness in the primeval forest, the arrow is the bronze casting used, the bowstring is the animal tendon, as for the arrow shaft and the feather used to fix the direction after the arrow shaft, it is selected according to local conditions, the feathers can be obtained by Xu Ran to help them capture large-sized birds, and the arrow shaft needs them to carefully select the straight and symmetrical trunk branches and fine processing.

The range of the bow and arrow made in this way can reach 50 meters, and the range of its effective lethality can be 30 meters; This is already a fairly effective long-range weapon for primitive people, which greatly increases the offensive and defensive capabilities of primitive people; Importantly, women could also use this bow and arrow within the tribe, so it was very popular with primitive people.
