Chapter 253 The upgrade of the hideout fortress officially begins.

Wang Bohu fired a magazine of bullets, pulled out a new magazine from the magazine with his left hand, then changed the bullets with one hand and loaded the gun with his backhand in one go.

At this time, because his attack stopped, the pursuer attacked and quickly approached him.

But soon Wang Bohu realized something was wrong. There were only two gunshots. What about the other person?

Just as he secretly said "not good", knowing that the last person must have approached him, he was ready to move to another position and escape immediately.

Boom....

Suddenly, a sound like a cannon firing sounded, which made Wang Bohu's scalp numb.

Then, he heard a crackling sound not far behind him. Looking back, he saw that a pursuer had fallen to the ground ten meters away, and the glass wall next to him had been broken.

Another gunshot sounded.

Although it was not as loud as the previous gunshot, it was also shocking enough.

A scream came, and the second pursuer was knocked to the ground.

Wang Bohu was a little confused.

"What's going on? Someone is helping me!"

Just when he had this thought, the gunshot rang out again.

This time Wang Bohu could see clearly that the sniper was located on the tall building about three or four hundred meters away from him.

Without thinking, Wang Bohu already knew that the last pursuer must have been sniped and killed on the spot.

Without time to think, Wang Bohu hid his body tightly behind the bunker.

He didn't know the sniper now, and was afraid that he would become the next target of the opponent.

But at this moment, his private chat message suddenly lit up.

Wang Bohu's mind moved, and he checked it immediately.

It turned out to be Tang Yu's message. When he opened it, he smiled and stopped hiding immediately, but ran towards his next destination immediately.

Just because Tang Yu's message only had three words.

"Hurry up and leave!!!"

There is no doubt that the last day before the disaster really opened the eyes of many survivors in Quelu City, especially the survivors of the Ten Thousand Races who entered with Tang Yu, all of whom were trembling at the moment.

It's too scary.

But the survivors who still have the energy to check the regional channels are basically those who have made preparations for the flood disaster in advance.

For example, those survivors who have neither closed facilities nor boats have left their hiding places with supplies as early as yesterday and went to higher places to avoid the flood.

After helping Wang Bohu kill three pursuers, Tang Yu and Little Raccoon immediately went to the evacuation point and returned to the hiding place.

Seeing the two people successfully return, Tu Shanxi, Xiao Ba, and the technicians all came over.

Because they know that the time for the hiding place to be upgraded to a fortress is finally coming!

Tang Yu looked at Little Raccoon.

"Rocket, have you used all the damaged hiding place deeds?"

"There are still two that haven't been used!"

"Use them all!"

All the hiding place deeds that Tang Yu obtained have been used.

The area of ​​his hiding place has now reached 3,200 square meters. After Little Raccoon uses all the hiding place deeds, the area has reached 3,400 square meters.

Tang Yu thought about it. Now the area of ​​the two of them alone is nearly 7,000 square meters, plus the 3,500 square meters of the fortress upgrade.

After the blueprint is added, the total area will directly reach more than 11,400 square meters, which is really too big!

This area has completely exceeded Tang Yu's previous estimate of the hideout. The main reason is that they have killed too many survivors of the Ten Thousand Races in the past two days and merged a lot of land deeds to increase the area.

However, Tang Yu has also thought about this problem.

The total number of floors in the hideout can still be built according to Xiao Ba's previous design. The only thing to consider is the area of ​​the vehicle transformation room on the underground floor.

The vehicle transformation room designed by Tang Yu before was completely designed according to normal vehicles, but he accidentally obtained two armed helicopters last night, and his idea suddenly changed.

Especially the [Missile Production Workshop Construction Drawing] purchased last night.

Tang Yu immediately knew what kind of area he should have the most-a mechanical factory.

That's right, it's a mechanical factory.

This mechanical factory can not only park various large and small vehicles with different functions, but also the missile production workshop will be built here in the future.

Here, not only can general vehicles be modified, but also various special vehicles can be modified in the future, just like the two armed helicopters in hand now.

This place will be built by Tang Yu into a mechanical modification laboratory.

Therefore, the overall area of ​​this area will be expanded to the maximum, directly occupying two-thirds of the entire hiding area.

The remaining one-third of the area will be divided equally by the remaining 8 floors.

In this way.

The mechanical modification laboratory on the first underground floor will have 7,500 square meters, and the area of ​​each of the remaining eight floors will be about 480 square meters.

At present, it is completely sufficient.

Other designs can still be based on Xiao Ba's previous design drawings.

With this idea.

Everyone came to the track of the Garden Subway Station and looked at the security gate of the hiding place.

Tang Yu took out the hiding place upgrade drawing.

With confirmation of use.

The upgrade drawing turned into a stream of light, and the corresponding hiding place design page appeared on Tang Yu's panel.

Tang Yu, who was familiar with the process and had already had experience last time, immediately began to divide the functional areas of the hideout and adjust the location of facilities and floors according to his previous ideas.

Some areas on the same floor will also be separated by separate partitions or single rooms.

Just like the living and resting areas, Tang Yu needs to leave a separate room for each employee.

And the most critical underground floor, the mechanical transformation laboratory, was extended out by Tang Yu alone.

480 square meters overlap with other floors, and the remaining more than 7,000 square meters were extended out by him alone, so that there will be solid land under the area extended out alone as support.

After that, all large and dense vehicles will be placed in this position to avoid affecting the safety of other floors.

The only difference is that he not only needs to adjust the location of the facilities in his own hideout, but also the facilities in the raccoon hideout.

So Tang Yu picked and chose, and eliminated some of the functions that overlapped with his own, as well as the infrastructure, and the rest were some hideout facilities built by the raccoon with special functional effects.

Tang Yu placed these facilities on the corresponding floors according to their functional effects.

For example, the vehicle modification workshop, parts processing furnace and other facilities were placed in the underground area.

In fact, there are still many special facilities in the raccoon, which also supplement Tang Yu's hiding place to a certain extent.

All settings are completed, and the upgrade of the hiding place begins completely.
