"Very good, even if you take care of the overall situation, come here, kill all the people here, and don't allow anyone to escape." After getting what he wanted, Zhao Mu did not hesitate and immediately gave this order.

If it weren't for the fact that they had been waiting for this kind of thing in their hands, this research institute would have been closed a long time ago, this group of self-righteous guys, what they did in private, they still naively thought that they didn't know it, but how could they have thought that some of the small animals or mutant beasts they usually did were sent over by Zhao Mu himself after being subdued by using the beast control technique.

Therefore, in less than a month, Zhao Mu had already figured out what this research institute was doing, and the reason why he didn't do it was just for the thing in his hand.

At this moment, the grenade-sized thing in Zhao Mu's hand was actually a newly developed YFS poison gas bomb, which was specially researched for alien monsters.

As for where the recipe came from, this was naturally the treasure map that Zhao Mu got from the secret door of his wardrobe when he killed the original Nanguang City Lord at that time.

At that time, after Zhao Mu occupied Nanguang City, he immediately took his two daughters to find the underground secret vault of a reservoir built by the former Nanguang City Lord more than a thousand miles away according to the treasure map.

And this secret room did not disappoint Zhao Mu, it really contained a lot of material wealth, it turned out that this was the capital of a former Nanguang City Lord to make a comeback after his failure at the end of his life.

Not only are there a large number of Yuanjing energy blocks, food and other living resources, but also a large number of the most advanced weapons are buried.

Including the most previous Thor single heavy cannon that Zhao Mu had exploded from the mutant leader before, there were more than thirty of them, and there were only three of them with product light.

This made Zhao Mu find out and be ecstatic.

The greater benefit is that the Nanguang heavy machine gun obtained before, there are also two hundred and fifty buried here, of which there are also eleven equipment products that can be used by those who are able.

The rest of the machines, such as light machine guns, have different big gains. Even the all-ground land combat armored vehicles actually have three, which belong to the type of equipment products, and they were all stored by Zhao Mu on the spot.

There are also 300 sets of mutant armor, mutants and other supporting sets, of which there are also eleven sets, which are completely equipment products.

Not to mention, Zhao Mu also got the seed products belonging to the white ground mushroom in this treasure house.

So this time the harvest. It simply made the three of them think that they were lucky, and in the limited world challenge, they got so many dropped equipment products at once, and it really deserved to be a treasure map.

But the even more amazing harvest is still to come, because Zhao Mu is in this treasure house, and he also got a nerve gas bomb recipe that can specifically restrain alien monsters, but because the formula is not perfect, so. Zhao Mu then brought it back and handed it over to the research institute to continue to complete.

And now, Zhao Mu has finally succeeded from the other party's well-researched method of preparing poison gas bombs, and now he will naturally not continue to let the hidden scourge of the research institute stay.

In fact. A series of high-level leaders of this research institute were actually arranged by the Dragon City of the three major settlement cities, and the former Nanguang City Lord had long known about this.

"Alright. This formulation is in hand now, and it has to be manufactured quickly, of course. This preparation process must be held tightly in our hands, and you should understand how much of an impact it will have on us once this gas bomb recipe for restraining alien monsters spreads to others. Zhao Mu immediately asked Tie Yi to complete this matter in person.

This also can't allow him to be careless, after all, this nerve gas bomb is mainly developed for alien-skin monsters, they not only restrain alien-skin monsters, but also restrain the clone monster army under Zhao Mu's hands.

Therefore, Zhao Mu naturally did not allow it to spread to outsiders.

Five days passed quickly.

Zhao Mu was right, the entire Nanguang City was extremely resistant, and it was enough to resist for a full five days before the monsters gathered and rushed out of the forest.

In this process, Zhao Mu even did not hesitate to use a large number of bombers and air and space fighters, and various combat armored units on the ground were also dispatched together, completely regardless of the loss, he held the defense line on the outskirts of the forest in the field, and shook the monsters on the opposite side for five days.

Originally, the absolute superiority of the sky and the continuous bombardment firepower of the human war were definitely not easy for the monsters.

However, this situation, which had been maintained for a long time, was shattered when the monster possessed the bare-skinned flying monster.

Therefore, even Zhao Mu and Helian Qingwu, plus Zhang Ning and the three of them went into battle to protect the aerospace fighters and bombers.

However, as a steady stream of monsters flew up from the ground and pounced, by the fourth day, the entire Nanguang City's sky armed forces were exhausted.

Except for the five Speed Eagle gunships left behind by Zhao Mu in the end, as a way for the wooden soldiers to escape, all the sky power was thrown into force and was disabled by the monster.

By the fifth day, the base was full of armored troops on the ground fighting to the death, so as to resist another day.

By the sixth day, the monsters gathered in the forest had broken out of Zhao Mu's defense line that had blocked the five-day defense, and then all the troops came to the city and launched a surging attack towards the Nanguang survivor settlement.

At this last moment, Zhao Mu had no choice, so he tried his best to fully press on the strength of the five major legions that had been built for a long time.

A total of 150,000 fully armed soldiers, all of whom were guarding the walls of Nanguang City, fought to the death to defend their homeland, and all guns, ammunition and weapons were distributed.

Even among the survivors temporarily, 300,000 young and strong survivors were drawn out to join the defense battle.

But even so, the attack launched by the alien monster this time was still fierce and abnormal, looking at the dense monster charging all over the mountains outside the city, even Zhao Mu, a super capable person, was numb.

Only by experiencing this huge war yourself will you feel how insignificant the power of the individual really is.

Although Zhao Mu's six satellites were full of firepower, in the eyes of all the survivors and soldiers, Zhao Mu had turned into an extremely powerful demon god at this moment.

Every now and then, a large number of monsters rushed to his side, and they fell one after another.

But...... The number of monsters, but it's still too much, tens of thousands? Several hundred thousand? Or even millions?

Everyone didn't know how many monsters there were, you know, even the lowest level of bare-skinned monsters, their strength was enough to reach the level of more than six worlds. (To be continued.) )
