Sending away the scientists who asked for money, Huang Chong lay alone on the sofa in the command room, thinking about how he should go on the road in the future, now the base has been upgraded to the second level, and the chariot factory has also been built, what the base lacks now is the oil that drives the chariot and the energy that makes the base develop rapidly, and these two things are available outside the forest, and the energy mining vehicle can now extract ore every day to refine it into energy belt points, so what is lacking now is oil.

And if you want to get oil, you have to go to the prairie outside, and the most important thing now is that there is still one thing missing, that is, the sub-base car, after all, if you don't build a base on the grassland, you can't build a high-tech oil well at all, and the base in the canyon can't build things from such a distance.

However, what made Huang Chong distressed was that he had just checked the chariot factory and found that even if he built a combat laboratory, he still hadn't unlocked the sub-base vehicle, which made Huang Chong a little worried, if he couldn't build a sub-base vehicle at the second level, his development would be greatly restricted, and if he only guarded this one base, he would not be able to carry out large-scale riots in a short period of time.

Now the only hope is the maintenance factory that is still under construction, after all, this is the last unit of the secondary base, if the maintenance plant is built and the base has not unlocked the sub-base car, Huang Chong has to think about moving, after all, there is really a shortage of various resources in this forest, especially the oil that is most needed now, and the brain has not detected it in this forest.

Huang Chong, who had thought about these things clearly, was in no mood to do anything else, anxiously waiting for the completion of the construction of the maintenance factory, while begging his grandfather and grandmother to pray that the chariot factory could unlock the production of the sub-base, while walking around uncomfortably.

"Drop" I don't know how long it took, but the sound of the completion of the construction finally came.

Huang Chong looked at the new maintenance factory that appeared on the screen, and dragged the mouse to the icon of the chariot factory with some trembling, success or failure in this move, and it depends on whether it is a dragon or a worm in the future.

"Drip, drip, drip" Just when Huang Chonggang clicked down, the lights in the command room suddenly flashed, a red one on the screen was turning, and a burst of alarms came.

"Didi, Didi, alarm, base is out of power, base is out of power" The voice of Zhi Brain sounded in the command room.

"Hmm" Huang Chong frowned and looked at the flashing lights, it turned out that after building one more maintenance plant, the power of the base was no longer enough to support the operation of so many units, Huang Chong could only think of ordering a power plant to build, at this time he missed the nuclear reactor very much, with that, there was basically no need to worry about the power problem, but unfortunately, now don't think about it.

Huang Chong, who was interrupted from the operation, continued to control the mouse to the icon of the chariot factory, and closed his eyes in a little daring to look at it. Then he clicked the OK button hard.

After a long time, Huang Chong's eyes gradually opened a small slit, and through this small gap, he saw that the units in the chariot factory had become seven, looking at the familiar rectangular car, Huang Chong breathed a sigh of relief, and jumped up from the sofa with a happy face.

"Yes, base car, I love you to death" Huang Chong couldn't wait to ensure that the base car icon on the screen kissed a few times to express his joy.

Huang Chong quickly put the mouse on the base car icon, and a line of introduction appeared next to the base car.

The first-class Red Police base vehicle produces energy points of 100,000.

"Well, 100,000," although Huang Chong expected that the base car should not be cheap, he didn't expect that it would be such an expensive price of 100,000 energy points.

Looking at his tens of thousands of energy points on the screen, Huang Chong was a little helpless, the base car could not be produced for the time being, it should take a few days, and he also had to prepare some things, in this way, it would be ten days, ten days should be enough, and he would set off in ten days, first go to the grassland to occupy a small area where no one is around, build a scientific and technological oil well, and let the combat vehicles he produced be useful.

Huang Chong set himself a short-term goal of ten days, and in these ten days he had to prepare things for this trip.

Next, Huang Chong went out of the command room and came to the military factory, and placed an order for 50 40 mm anti-aircraft guns and 100 12.7 mm anti-aircraft machine guns to the military industry.

Huang Chong's custom batch of anti-aircraft guns and anti-aircraft machine guns were specially prepared for Wan Yan Lie, after all, the prairie he was going to next was someone else's territory, so it was better to be well prepared, and Wan Yan Lie's fierce appearance last time still remained in Huang Chong's mind.

In the next ten days, Huang Chong lived a life of idleness, eating and waiting for death, every day as soon as the mining vehicle came back, the energy point would be squandered by Huang Chong, in these ten days, in addition to leaving 100,000 energy points to build a red police base car, other energy points were produced by him 5 snipers and caused a rhinoceros tank, the energy points that can be mined in ten days are 400,000, 100,000 are given to the military factory, 100,000 build base cars, and the remaining 200,000 are produced 5 snipers plus the sniper rifles they are equipped with, each of which is 16,000, 5 people is 90,000 energy points, and the remaining 110,000 plus the original tens of thousands of energy points to create 18 rhino tanks.

Of course, Huang Chong didn't want to bring so many tanks to the grassland, he didn't have so much oil, the purpose of building so many tanks was for the two fuel tanks that came with the tank, now Huang Chong has a total of 28 tanks, he can only take 4 tanks out together, and all the oil from other tanks is used as spare oil for these four tanks, in order to start these four tanks, Huang Chong also built 6 more tank soldiers, plus the original ten, just one tank with 4 people, in order to build 30,000 energy points for these 6 tank soldiers, Huang Chong also stayed in the canyon for one more day, which was originally planned to be ten days, but it was not prepared until the eleventh day.

Early in the morning of the twelfth day, Huang Chong stood at the gate of the canyon in full gear, Huang Chong will leave the canyon for the second time to reach the outside, only once he brought more people than last time, this time with Huang Chong set off with two infantry regiments of more than 5,000 people, and an artillery regiment of more than 2,000 people, in addition to four tanks, 6 snipers, and a base car, especially the infantry regiment is also equipped with 50 more anti-aircraft guns and 100 anti-aircraft machine guns, it can be said that the strength is much stronger than last time, originally Huang Chong also wanted to improve the strength of the artillery regiment, After all, the power of mortars is a bit small, and the current military factory can already produce field guns or howitzers, but unfortunately the time is a little short, Huang Chong can only settle, thinking about the construction of scientific and technological oil drilling wells to study the artillery regiment to change equipment.

There was no exciting declaration of "departure", after Huang Chong said two words lightly, he got into the multi-functional infantry vehicle specially prepared for himself, the carriage has been transformed, there is a bed and a table or something, and it has basically been changed into an RV by Huang Chong.
