One day, two days......

Morning exercises, noon and afternoon rescue and search, and evening training for survivors and infantry confrontation, everything in the fortress is developing in a good direction

As Li Wenbin and his men continued to move, there were more and more survivors in the fortress.

Finally, six days after the outbreak of the apocalypse, most of the entire area of Yunnan-Guizhou University was cleaned up by Li Wenbin and others, not only obtaining a lot of supplies, but also saving many surviving teachers and students.

However, it is a pity that apart from Liu Yajun, he did not meet any other evolutionary after that.

Now, in addition to the subordinates summoned by Li Wenbin himself, the population of people inside and outside his fortress has reached nearly a thousand, including more than a dozen teachers. Men accounted for the majority, about 600 people, and about 300 girls. It has reached the limit of the alien population that a Level 1 Doom Fortress can contain.

Any more, and the proper functioning of the fortress will be problematic.

After considering it comprehensively, Li Wenbin finally decided to upgrade the fortress to level 2.

In fact, as early as the third day, the energy points he obtained were enough to upgrade the Doomsday Fortress, but Li Wenbin did not do that, but further strengthened his strength and laid a good foundation.

Now the overall combat effectiveness of the fortress is no longer the same.

The farmer is still thirty people, but he has been upgraded to level 3, not only the combat power and the speed of collecting materials have been improved, but the upper limit of collection has also reached 20.

The real change is the infantry.

The 158 infantry have already been summoned, and all of them have been upgraded to level 3, and their combat power has reached 8 points, which is extremely powerful.

Not only that, under Li Wenbin's instructions, only a small amount of the materials collected by the farmers were used for daily food conversion to ensure the basic food supply, and the rest were basically used for the equipment and materials of the infantry.

Each infantry had a standard set of equipment: a long sword, a shield, and a battle armor.

The battle armor, which is mainly composed of cuirass, arm guards, and leg guards, is sewn with soft wire connections, which is light and does not affect the battle, which is a great improvement for the combat effectiveness of the infantry.

With the battle armor, they can attack the zombie group more unscrupulously, and according to Li Wenbin's understanding of the enhancer in his previous life, the combat effectiveness of a single infantry now can be compared to a first-order early enhancer, and the team combat is far beyond it.

As for the battle against the Evolutionary, this one is hard to say. The abilities of the evolutionary are strange, the strong ones are likely to be strong to the point of perversion, and the weak ones are not even as strong as the enhancers of the same level.

Take Liu Yajun as an example, after Li Wenbin's teaching, he is now able to fight back and forth with the four infantry who formed a battle formation, and no matter how much he has, he will not be able to take advantage.

In addition to the infantry, the number of foreign troops has now reached about 600. Among them, there are more than 500 boys and about 100 girls.

Under the deployment of Li Wenbin and others, the external units implemented a simple team allocation.

20 people are a squad, five squads are a squadron, and five squadrons are a brigade.

Liu Yajun lived up to expectations and was elected captain with a strength second only to Li Wenbin, while Yan Kuan also became the deputy captain with his character and the highest prestige to assist Liu Yajun.

Below them, there are some people who have performed well in the follow-up, divided into squadron leaders and squad leaders.

Compared with the boys, the number of female out-board troops is much smaller, only about 100 people. Most of these hundred or so people have not participated in the battle against zombies from the outside. Their main task is to clean up the materials after the boys have dealt with the zombies.

There is only one team for girls, which is commanded by Huang Yun.

As for the boys and girls who didn't dare to participate in the battle, they were all managed by Yunmeng, responsible for all the daily chores in the fortress, and these people were treated much worse than those who participated in the battle.

In addition, the Lightning Mother Tree has also been upgraded to Level 1, and ten Level 0 Flash Electron Trees have been differentiated. The ten Flash Electro Trees will also soon be upgraded to Level 1.

Li Wenbin once again got two new lightning fruits.

With the help of the Doomsday Fortress, the two lightning fruits raised his strength to the peak of the mid-first order, and he was almost able to reach the late first order.

Don't underestimate this mid-first-order stage, the current Li Wenbin's physique has reached six or seven times that of ordinary people, and the total amount of lightning crystal power in his body is a few points more than the peak of the first-order in his previous life, and his strength is even more crushing.

If it is rated according to the star rating, the current Li Wenbin can be rated as a four-star powerhouse, and even a five-star king-level powerhouse.

Overall, at this stage, both the individual strength and the comprehensive strength of the fortress have reached a critical point, and it is time to upgrade if you continue to hold back.

Doomsday Bastion!

With Li Wenbin's thoughts, the interface of the Doomsday Fortress appeared in front of him, his fingers dotted, and a prompt immediately popped up.

——

(Fort of Doom has met the upgrade conditions, is it upgraded?) Yes/No)

——

Be!

Li Wenbin took a deep breath and made a choice.

As he made his choice, a loud bang suddenly appeared, which shocked Li Wenbin in a trance, but the others in the fortress who had been ordered not to go out did not have the slightest abnormality.

Soon, however, they felt it.

The Doomsday Fortress began to show slight tremors, not noticeable, but they were there.

As the tremors appeared, the entire fortress began to spread outward, and slowly rose, bounded by the city walls, as if something was on top of it, and the whole fortress was uprooted from the ground.

Finally, when the area of the fort was doubled and the height was increased by ten meters, the interior stopped changing.

Outside the fortress, the changes continued, and under the four walls, four bluestone staircases with a width of up to a thousand meters slowly appeared, starting from the bottom of the city walls and extending diagonally downwards until they connected the walls with the ground below.

After the staircase appeared, a radar-like aperture centered on the main hall of the city quickly radiated, and soon, like a frame, the entire Yungui University and some other areas outside the university were framed together, forming a large square.

This is the area occupied by the Level 2 Doomsday Fortress, which is 10KM long on one side, which is 10 times that of the Level 1 Fortress. It covers an area of 4 million square meters, which is about twice as large as the entire Yunnan-Guizhou University.

After the division of the scope, the renovation and construction of the Doomsday Fortress also began, and unlike the level 1 Doomsday Fortress, the level 2 Doomsday Fortress has not changed much, to be exact, it is just a new wall than the level 1 fortress.

Just like when the previous level 1 fortress was built, the position circled by the radar aperture, four solid walls began to rise from the ground, enclosing the territory of the level 2 Doomsday fortress inside.

Compared to the walls of the Tier 1 Doomsday Fortress, the walls of the Tier 2 Fortress are ten meters high and five or six meters thick, and the material is obviously better than the original walls.

Above the ten-meter-high wall, there are concave notches every fifty meters, and the aisle in the middle has become four meters wide.

When all four walls were completed, the primary construction of the Level 2 Doomsday Fortress was completed. Aside from an increase in the scope of the territory, four more walls, and a height of ten meters from the previous territory, there are no changes to the level 2 fortress.

Disappointed?

No, Li Wenbin was not disappointed at all, because he knew that this was only the primary transformation of the level 2 apocalypse, and the real change must be carried out by him, the master, himself.
