The leaders of the three mercenary groups were surprised, and when they charged, as they imagined, the firepower of the Oasis base suddenly weakened.

However, after their rapid advance, the result was overwhelming firepower, and there was a sound of cannons, a 155mm howitzer, and a dozen mortars, which became a life-threatening charm, and the crazy slaughter began!

There are also millions of bullets in the Oasis base, launched a frantic attack, in a moment, it killed more than a third of the mercenary group members.

Even the members of these mercenary groups are experienced in a hundred battles, but they fight separately and do not know how to cooperate on a large scale, they are simply live targets.

The machine-gun fire completely suppressed them and couldn't raise their heads, and at this time, the soldiers who were waiting for them began to shoot one by one.

Although they are not sharpshooters, but the cruelty of the last days makes people don't care about human life at all, so their attacks are extremely fast, but in just ten minutes of fighting, the enemy army has suffered heavy casualties!

Blue-level zombies, under the overwhelming fire attack, can only be killed, these mercenary groups, now there is nothing they can do!

"Retreat, retreat!"

People's hearts were panicked all of a sudden, and the head of the mercenary group hurriedly shouted, the Black Tiger mercenary group, take the lead and start retreating!

And the defeat was like a mountain, and some people retreated, so there were more people retreating, and suddenly the three mercenary groups retreated frantically.

"Is it that easy to run?"

A sneer leaked from Chen Rui's eyes, and finally he had been pressing the more than 100 soldiers who had not moved, and began to dispatch, each of them had an automatic rifle in his hand, which could be used as a light machine gun, and the bullets were fully equipped, so he had already been prepared, and suddenly the city gate opened and rushed out.

In this battle, the three major mercenary groups were directly and completely disabled, and there were only a few people who could escape, and the rest, including the heads of the three mercenary groups, were all swept away.

The next day, the endless corpses on the battlefield were burned by a fire, and the burning smoke could be seen in the wilderness base from afar.

And the Wasteland Base Administration has finally begun to pay attention to it, and unconsciously, the Oasis Base has actually grown to this point.

Suddenly, the Wasteland Base Authority held a plenary meeting and passed a restriction plan for the Oasis Base, restricting the trade in original ammunition.

It's just that what they don't know is that the Oasis base now has a small arsenal, although artillery shells and machine guns cannot be produced, only steel bullets can be produced on a large scale, but they no longer have to worry about the containment of the wasteland base.

Zhao Feng has a good relationship with many small underground factories in modern time and space, in this era when money is everything, the civilian equipment and some machines in this world have been built under the leadership of Lin Gaofeng, a military expert, to build a real arsenal, even if it is the smallest small arsenal, but there is no need to worry too much.

Now the only thing that can be stuck in the wasteland base is probably oil, but the transaction between the end of the world and modern time and space makes Zhao Feng have a lot of money now, and he doesn't have to worry about supporting the fuel used by the team.

Through a certain foreign trade relationship, the oil of the underground refinery, that is, how much there is.

These are all the strength that has laid Zhao Feng, and Zhao Feng doesn't have to worry too much about anything anymore.

"This time, everyone has worked hard, everyone's reward has been doubled, and the other people are immediately gathered to expand the escort team to two thousand!"

The measures taken by the wasteland base, Zhao Feng naturally got the news, and said with a sneer.

"Yes!"

The manufacture of guns is actually not so difficult, but the safety factor and stability coefficient of civilian guns are not too reliable, but now the rifle production in the arsenal cannot be achieved on a large scale for the time being because of machinery and equipment, so Zhao Feng directly ordered to buy materials at a high price from various hunters.

Then it was handed over to the arsenal for maintenance, and now Zhao Feng knew that the wasteland base had already taken precautions, so he would go all out to produce weapons and ammunition as much as possible.

In the next three days, the Oasis Base will deal with everything, order will be restored again, and at the same time, it will begin to recruit refugees on a small scale, with the scale of the Oasis Base, large-scale construction of buildings and houses, there is no problem in accommodating 20,000 people, and if there are more, it can be accommodated, but the water supply will not be maintained, so for the next expansion, Zhao Feng made a plan with great care, and it must be absolutely reliable refugees.

After all, there are a lot of refugees, and careful selection from this is the king, although he also hopes to save more refugees, but he is also powerless.

There are only some ways to give the refugees some food to eat, and there is hope for them to live.

In fact, the Wasteland Base Administration, if you have the heart, it is not too much of a problem to feed more than 100,000 people, but the Wasteland Base Administration is used to that kind of high-altitude life, how can they save their rations and help more refugees.

The Grand Canyon base not far away, the same idea, Zhao Feng's ambition is also their **, Zhao Feng understands very well in his heart that only by aggregating the resources of the two bases can it be possible to attack Qingning City, a big city with a population of more than one million and now more than 600,000 zombies.

Only in those big cities can you gather more refugees, become a powerful force, and occupy more resources in these last days!

"In the past few days, I believe everyone is almost familiar with the new team, Wang Hu, you lead three hundred veterans to stay, and the rest are ready to go down, give everyone a day of rest, and then follow me to set off!"

Zhao Feng has long had an idea about the industrial zone, but it is just a series of variables, and he can't spare his hands at all, and now that more people have been recruited, and the guns and ammunition are complete, it is time to take this industrial zone.

Relying on the blessing of the three major mercenary groups, now this industrial area is only more than 10,000 zombies, and those industrial areas will be extremely simple!

"Boss, beware of the wasteland base!"

Chen Rui said with a worried face.

"Don't worry, Lao Chen, as long as we are fast, with the decay of the wasteland base, when we know the news and make a decision, we will hurry up and transport the industrial equipment in, hum, we have made so many preparations, this is our best opportunity!"

Zhao Feng said firmly, in fact, this time his crazy time and space shuttle, but also improved his physical fitness, while bringing a large number of materials, among these materials, there are some things that he was fortunate to get, I believe that as long as the industrial equipment can be transported in, then there is no need to worry about anything!
