With a bang, a huge explosion occurred at the entrance of the cave, and the passage to the underground was also revealed.

Zhuge Yao looked at the entrance of this passage, his brows furrowed, and things seemed to have changed again. The area around the entrance to this passage was not affected by the bombardment at all, except that the rockery above was blown open.

Everyone must know that after being hit by thousands of ground-penetrating bullets, how can there be nothing at all. The only explanation is that this is a formation, and it is very powerful.

Based on various data, he made a little calculation and came to a conclusion. No matter how fierce the attack is, if you don't find the core of the formation, it is impossible to continue to inflict damage. This means that even if the entire secret base is blown up, it will be impossible to go in and sweep it.

Around the entrance of the passage, there are five stone tablets, each with different inscriptions. Although Zhuge Yao didn't recognize these words, he could also guess that these stones were the core of the formation.

Although he didn't know what to do, Moon Shadow, who was standing on the side, took the initiative to drive the mecha out. Zhuge Yao was taken aback by this guy's actions, and hurriedly drove Long Yuan to chase after him.

The information of Moon Shadow's mecha had already been collected by Zhuge Yao, so he was frightened by the other party. This mech has a strong focus on stealth, so its armor is very weak, and so is the protective shield. If you are accidentally hit by an armor-piercing shell or a laser cannon, then there is only one result, and that is to be blown into scrap metal.

It's hard to find such a helper, but it can't be lost so inexplicably, it's a pity.

Long Yuan's protective shield, after being strengthened for the third time, is not only extremely strong in defense, but also can spread out. If you want to protect another mech, of course, it is not a problem, it just consumes some more energy.

Things were as Zhuge Yao expected, no matter how the airboat group was dropping bombs, it couldn't destroy this formation.

"Keep fighting, don't stop, use the bullet, and play the majesty of the Dragon Knight Legion!" Seeing that the attack was blocked, Li Aotian was very unhappy, and immediately ordered the air boat group to use submunitions.

As its name suggests, a large number of small high-explosive bombs are installed in a large number of small high-explosive bombs. This kind of bomb is different from ordinary bombs, not only has a wide killing range, but also has great power. Even with the guidance of towing rays, it is impossible to achieve accurate strikes, but the intensity of the air attack is doubled.

The formation at the entrance of the passage trembled slightly for a few moments, and then regained its calm. No matter how much the submunitions bombed, they were as stable as Mount Tai, and they would never move again.

But the surrounding star trees suffered, and after a large number of sub-bombs bombed, a mountain fire was triggered.

After seeing this video, Imperial Marshal Li Wuwei immediately issued an order to Li Aotian, asking the other party to stop acting immediately and extinguish the fire in the Xingchen Mist Forest first. It's no wonder that he was so shocked, the Star Tree is an important strategic resource of the empire, and if it is burned by the flames, then the energy crisis of the empire will become more obvious.

Li Aotian has always refused to eat Li Wuwei's set, but it is strange to say that this time, he did not refute the other party's order. Although the troops were not ordered to stop the attack, they sent some mechs down to the fog forest to extinguish the wildfire.

Fortunately, the forest is surrounded by rain and fog all year round, and the branches of the trees are relatively wet, so the damage caused by the wildfires is not very large. This small team of mechs came down and used a few cryo bombs to extinguish the wildfire.

Although this is just a trivial matter, Li Aotian's attitude was remembered by Li Wuwei. As the saying goes, if you are not afraid of thieves, you are afraid of thieves. Only a month later, Li Aotian was pitted to death by this imperial marshal.

Zhuge Yao followed behind Moon Shadow, originally thinking that he was going to destroy the formation, but it turned out to be completely different. This girl is a bad embryo, and she actually changed this formation, and it is very obscene to act.

And he seems to be worried in vain, even if it is a sub-mother bomb, it can't penetrate the protection of the formation. It's strange to say that Moon Shadow and Zhuge Yao were so swaggering, driving the mecha over, and swaggering back, but there was no.

"Coax!" There was a loud bang behind him, shaking the heart, and the huge wave of qi that came from it also scraped the mecha to the ground.

"Phew, Moon Shadow, what the hell are you doing, it hurts me to death." Zhuge Yao's head knocked out a big bag, and he didn't sit down firmly just now. He complained to Moon Shadow that the bullet was ineffective just now, but now it was so powerful.

Judging from the images recorded by the mecha, the formation that was originally resistant to bombing has become an energy amplifier. When the submunitions fell on the formation, the power of the explosion was amplified, and a large crater was blown out directly at the entrance of the passage.

"Hehe, Lao Tzu is amazing, I just made a move in the formation, transforming the original resistance array into an energy amplification array." Moon Shadow smiled wickedly, as if she was very satisfied with her masterpiece.

"Lao Tzu, you are big, dare to call yourself Lao Tzu in front of me, you deliberately find fault, right?" Zhuge Yao shot without warning, and pushed the Moon Shadow's mecha down, only to feel a little angry.

Moon Shadow also had a big bag on his head, and Zhuge Yao's attack speed was quite fast, and he didn't even have time to react, let alone dodge. He was very dissatisfied, but he didn't dare to say it, for fear that the other party would disagree and do it again.

After the formation at the entrance of the passage was destroyed, a large number of Warcraft soldiers rushed out of the passage. Among them, some giant flying monsters, I don't know how they got into the ground.

The Warcraft began to fight back, and countless spiritual missiles shot at the group of airships in the sky. Some higher-level Warcraft people can also fly with swords and soar into the sky like a ray of light.

The flying monsters also flapped their wings and quickly joined the battle. The bodies of some flying demonic beasts are even larger than the airships above, and as long as they are hit, they are estimated to be scrapped immediately.

Seeing so many Warcraft soldiers coming out, Zhuge Yao became very excited, and his hand holding the joystick was trembling. At this time, the Longyuan mecha was like a lion, lurking in the grass, waiting for the time to come, ready to pounce out at any time.

More and more Warcraft soldiers climbed up from under the ground, and there was no edge in sight. They had been hidden underground for a long time, and suddenly appeared in front of everyone, and the shock was self-evident.

In addition to a large number of high-level Warcraft rat people, there are also many third-level cave devils who cooperate with each other to fight.

Even Li Aotian was a little timid in his heart when he saw this number of enemies again. But he recovered quickly, what wind and waves have he never seen, and he will care about the opponent's numerical advantage?
