The maintenance passage is a bit like an escape passage in a high-rise building on Earth, with a slight turn to the ramp that leads to the next floor, all the way down to the lowest level.

Fang Qingshu and their next actions were the same as just now, using special grenades and secondary guns to suppress the impact of the biochemical dogs, using the main guns of the fighter planes to make a small hole in the door first, and then opening the gate and rushing down after the special grenades were cleaned up.

This kind of process is safe and fast, although there are a large number of low-strength biochemical dogs, but unfortunately they can't give full play to their advantages because of the narrow terrain, so they were killed by Fang Qingshu and them all the way to the tenth layer.

At the tenth level, the situation began to change, and for no other reason than because the guards here were no longer cyborg dogs, but a combination of strange birds and ironclad beasts.

The Ironclad Beast's defense is much higher than that of the Cyborg Dog, and although the special grenade can still inflict a large number of damage on them, the effect is significantly lower. If the special grenade blows up the biochemical dog, within a radius of 50 meters, it will definitely die, but if the ironclad beast is blown up, it can only kill within 30 meters, and the ironclad beast with a radius of more than 30 meters will only be injured.

So the problem that could be solved by one special grenade in the past now requires two. As for those sharp-billed monster birds, they are even more powerful, their speed is so fast that they are cleared out by special grenades, and in a few seconds, they can fly from behind and attack everyone again.

Fortunately, everyone was not a fuel-efficient lamp, Fang Qingshu and Ruoqin's flying swords, as well as the little girl's Chiyou Battle Spirit Banner, all went into battle together, so they could be regarded as blocking this group of small things.

Helena hid in the driver's cab, but she didn't have to worry about her safety. But this is only temporary, because the blood of these strange birds has a strong corrosive surname, although the materials of the fighters are many times stronger than the building materials, but they still cannot resist the corrosion of this biological acid. The original silver-white fuselage, but halfway through, it was corroded into pits, like a newly unearthed cultural relic.

The cockpit, in particular, has been subjected to concentrated attacks from strange birds, and in addition to its thinness, it has corroded a hole. Fortunately, Helena had two hundred degrees of energy shield on her body, so she was not injured.

However, the various precision instruments in the cab could not stand such a toss, and they went on strike under the erosion of acid. Helena finally said helplessly: "This thing can't be opened, otherwise I can't guarantee when it will blow itself up." ”

When Fang Qingshu heard the word self-explosion, he was startled on the spot, and hurriedly ran down, saying, "Everyone come down, let's get another one!" As he spoke, he took out another fighter plane and came out. I have to say, it's good to have a space ring. It's so easy to get things.

After changing to a new fighter, everyone finally barely crossed the territory of the strange bird and the ironclad beast and reached the twentieth layer.

After coming to the twenty-first layer, Fang Qingshu looked up and saw all kinds of strange-shaped monsters pressed by the black press. There are giant beasts that are ten meters tall, small creatures that are the size of palms and shaped like spiders, biochemical bats that fly in the sky, and biochemical geckos that can fly quickly on walls. There are no less than 100 species, and the number is even more vast.

Obviously, by now, Fang Qingshu and the others had also figured out the law of the monster division here, that is, every tenth floor was a dividing line, and the further down they went, the more powerful the biochemical beasts became.

Fang Qingshu couldn't help but complain while fighting: "Is the owner here opening a zoo? Why are there so many varieties?"

"Who knows!" Helena said with a wry smile, "However, they may have just started to study the Warriors, so naturally they need to make more varieties so that they can choose the right ones to focus on cultivating." So it makes sense to be like this. ”

"But I hate these enemies that I can't kill!" Fang Qingshu frowned and said, "Helena, can you find a terminal system?

"Sorry, everything here is out of power, the system won't start, and there's nothing I can do about it. Helena said helplessly.

"Huh?" Fang Qingshu paused for a moment and said, "Then what should we do?"

"It seems that there is only one way out for us. Helena explained, "Rush into the last layer and take the host directly, I don't believe it, they can still stop the host." In that case, these cyborg beasts will definitely be at a loss because they can't receive orders. ”

"The last layer?" Fang Qingshu couldn't help but have a headache as he looked at the group of biochemical beasts that were desperately charging, and asked with a wry smile, "What is the last layer?"

"I don't know, but it should be above the thirty floors. Helena said.

"More than thirty floors?" Fang Qingshu gritted his teeth and asked, "What if I can't rush in?"

"There's no need to worry too much, now that they've completely cut off the energy around us, and even the device that shields the spatial teleportation has been turned off, so we can escape with the space scroll. Helena laughed.

Fang Qingshu suddenly frowned, remembered something, and asked, "Didn't you say that only high-level shields can shield spatial teleportation, why can this low-level civilization too?"

"Because they don't use shields, but use solid metal layers, these are obviously two concepts!" Helena said with a smile: "If the solid metal layer is thick enough and filled with some disordered spatial energy flow, it is indeed easy to prevent others from using space technology to conduct intelligence spying, but this is not possible to use on warships at all?"

"Why can't it be used? Isn't it possible to make this metal layer into the outer skin of a battleship? This can also protect against space bombs?" asked the little girl puzzled.

"Defend against space bombs with metal skins, that must be crazy!" Helena smiled bitterly: "Space bombs are very large in size and even more perverted because they don't consider the problem of flight, and at worst they are comparable to giant nuclear bombs on the earth, even the skins of our Atlanteans' warships can't withstand a few hits, and the skins of the battleships of other technological races are rotten at all." ”

"Generally speaking, the only way to defend against space bombs is to first use an energy shield to block the bomb from the outside of the battleship, fully weaken the power of the bomb, and then rely on the armor of the battleship itself to hard-connect, once the space bomb directly hits the shell, the battleship is basically dead. Helena explained.

"Hehe, I've seen it again!" Fang Qingshu smiled: "Okay, don't think about the battleship now." Now that our space scroll can be used, then let's not be polite, hurry up and rush down, this time, we must find out the guy who is against us!" As he spoke, Fang Qingshu threw out more than a dozen special grenades with a shake of his hand, clearing up the large and small biochemical beasts in front of him.

Only a few of the strongest ones were still standing in place, a tall monster that looked like a rhinoceros and was covered in black scales. Just by looking at their ability to resist the bombardment of special grenades, Fang Qingshu could conclude that their strength was above level four, to say the least. Their corpses are treasures that can greatly nourish Gu worms.

Fang Qingshu naturally wouldn't let it go, only to see him suddenly turn into a meteor, jump up from the fighter plane, and go straight to the monster to kill.

Those few biochemical rhinoceros beasts had just been blown up by the special grenades, and before they knew what was going on, they were killed by Fang Qingshu. The shadowless flying sword instilled by the Heaven Splitting Force, under the swing of Fang Qingshu in the dragon state, the power was unimaginable. And Fang Qingshu's speed was extremely fast, just like a quick knife cutting through the chaos, but in an instant, several bull heads fell to the ground.

After putting away the corpse with the Qiankun bracelet, Fang Qingshu just wanted to speak, when he felt that something had bitten him fiercely on his foot. As soon as he hurriedly lowered his head, he saw a colorful spider coming to his feet at some point, desperately biting Fang Qingshu's toes.

Fortunately, Fang Qingshu is now in a state of dragonization, his whole body is covered by dragon scales, although the spider's sharp teeth can bite through steel, but he is stunned that there is no way to take this golden dragon scale, how to say that this is also the scale formed by the blood of the dragon god!

However, what made Fang Qingshu feel strange was that his scales were the same as authentic dragon scales, and there was obviously a strong energy shield on the outside, even if it was running well now, how did this spider break through the barrier of the wall and bite directly on his feet?

It was still on the battlefield, and he couldn't figure it out for a while, and he didn't have time to think about it, so he commanded the Shadowless Flying Sword to kill the spider casually, put away its corpse, and then reminded the others: "Be careful of your step, there is a kind of spider that will sneak attack." Don't get bitten, it's definitely poisonous. ”

"Oh, people hate spiders the most!" Ruoqin couldn't help but scream. There's no way, most of the girls are afraid of this kind of thing, even Ruoqin is not immune.

Helena smiled and said, "What are you afraid of? Don't forget, you have black dragon leather boots on your feet, no matter how powerful this spider is, can it still bite through the dragon skin?"

"Ah, that's right, I forgot about it in a hurry!" Ruoqin smiled helplessly.

Fang Qingshu shook his head with a smile and said, "Okay, hurry up and assault!" As he spoke, he returned to the fighter again. Helena then piloted the fighter plane and began to advance.

I have to say that the monsters of these ten layers are much more powerful than the monsters of the top twenty layers. It's a world of difference. Not only do they have powerful rhinoceros beasts that can resist the attacks of special grenades, leading a group of little brothers to attack Fang Qingshu's fighter head-on, but they also have several small-sized biochemical beasts such as colorful spiders, which specialize in sneak attacks in dark corners, which are really unguardable, and even the little girl with the highest alert surname has been bitten several times one after another.
