Zhao Tong was also worried that he wouldn't be able to support it for long, so he went all out and walked quickly, although the underground environment was complicated, he was like his own backyard, Rao was like this, he stopped and stopped, and it took more than an hour to bring Yan Yu and the others to their destination.

This place is also a stream of water, and the surrounding environment is not much different from before, Yan Yu and the others even have an illusion, almost thinking that they have turned back to the original place.

The difference is that the water here is slightly more turbulent, and the flow direction is not the same, simply put, Zhang Gulin's place is the water outlet, and this seems to be the water inlet!

Sure enough, Zhao Tongyi breathed a sigh of relief and explained to everyone: "This is the entrance to the underground base, although the passage is wide, it is very long, and there are a few filters at the end, so you can't enter without diving equipment." ”

Yan Yu had also worried earlier that he, Zhao Tongxuan and others might hold their breath longer than ordinary people, but it was impossible for them to walk under the water like a fish.

Fortunately, Zhao Tongyi had already planned this route, so Yu Guofeng and the others all brought diving equipment, although they were all small oxygen cylinders and breathing masks were also very simple, but they should be enough.

Although Meng Jiefang and the others went back, the equipment was left behind, and it was more than enough to spread it evenly.

Zhao Tongyi looked like the end of a strong crossbow, but he no longer rested at this time, just like a lost person who struggled to move forward in the desert, and if he stopped, he would never get up again.

Due to the relatively simple equipment, it didn't take much time for everyone to put it on, so Zhao Tongyi bit his breathing mouth and took the lead in stepping into the river.

As they continue to move forward, the convergence effect of the water inlet is still visible, the closer they are to the water inlet, the greater the suction of the water flow, Yan Yu and the others do not need to exert force at all, just relax, and they will be dragged forward by the water flow.

Later, a huge whirlpool formed in front of the water inlet!

Because they were biting their mouths, they couldn't speak, so they let the water pump themselves into the pipes!

The pipe is very wide, but the surface adsorbs a lot of parasitic organisms, and after keratinization or petrification, it is full of sharp thorns, and collision and scratching are also very dangerous.

Yan Yu could only protect his head, like a curled hedgehog, drifting with the tide, and then collided with another person, and everyone crashed into a ball!

Because everyone blocked the flow of water, the suction and pressure were quite large, and it took a lot of strength to Yan Yu to struggle to push everyone away.

In front of it is a huge iron fan with blades like a giant guillotine, a shredder that relies on the flow of water to crush large volumes of garbage!

It is also thanks to Zhao Tongyi, Yu Guofeng and others who decisively stopped everyone, otherwise I am afraid that they will be cut off by this crusher!

Zhao Tongyi should have studied it, and at this time, he pulled out Yan Yu's Pure Yang Sword, wrapped it on his back, wrapped several backpacks with the Pure Yang Sword, and lowered it down the water, which stuck the crusher.

Everyone breathed a sigh of relief, and they were afraid to drill through the gap in the crusher, but the backpack was entangled in the blades, and there was no way to retrieve it, so Yan Yu had to pull out the Pure Yang Sword.

Several people continued to move forward, and the closer they went, the greater the impact of the current, and they could not even control their bodies at all, so that everyone crashed into one place and stopped again.

I thought it was another shredder, but it turned out to be okay, because what stood in their way was a filter.

Yu Guofeng had obviously discussed this plan with Zhao Tongyi, and he, Guan Rui and the others quickly took out tools and began to disassemble the huge filter.

The strainer was made of steel, the screws had long been bitten by rust, and it was difficult to exert force underwater, and the pressure was so great that it was difficult to stretch out their hands and feet.

Although several people cooperated, the filter was not successfully removed as time passed!

They are carrying small oxygen cylinders, the capacity is not very large, if they can't break through the filter for a long time, not to mention the excessive physical exertion, the oxygen can't hold up.

If you turn around at this time, the oxygen may still be enough, but the suction is too strong, and it is difficult to stretch your hands and feet, let alone go upstream.

Yan Yu believes that everyone knows very well that there is no way back at this moment, either open the filter or die in the passage!

Yu Guofeng, Zhao Tongxuan and others tried for more than ten minutes, the screws seemed to have been fused with rust, they didn't move at all, and the tapping in the water was very weak, and the more anxious everyone became!

The oxygen cylinder was only the size of an arm, and although it was compressed gas, it could not withstand long-term consumption, and Yan Yu himself felt that the airflow of the breathing nozzle was gradually weakening.

He patted Zhao Tongxuan on the shoulder, grabbed Yu Guofeng again, and made a gesture to them to get out of the way.

Yu Guofeng and the others didn't understand, Yan Yu couldn't control so much, his feet were propped up on both sides of the pipe, his hands and feet were used together, and he began to swim upstream!

Everyone thought that Yan Yu was going to turn back, and they wanted to stop them one by one, but Yan Yu went backwards regardless of it.

His hands had been cut, his inferior gloves had long since been broken, and the bandages that had wrapped his wounds had been cut.

After about three or five minutes of retrograde, although the distance was not too far, he felt a little less pressure, so he let go of his hands and feet, kept his head, adjusted his position, and let the current impact him!

Everyone finally understood Yan Yu's intentions and retreated one after another!

With the impetus of the water, Yan Yu kicked forward with his feet, and under the force, the filter shook violently, rolling up a burst of turbidity!

Yan Yu's feet were numb to the point of pain, but he still didn't stop and continued to go retrograde!

After everyone realized Yan Yu's intention, they also followed, and several people gathered in one place, and because the pipe was blocked, the impact was even greater!

Yan Yu took the lead in letting go of his hands and feet, and everyone was also rushed down!

"Bang!"

There was a muffled sound, and the frame of the filter was still there, but the filter was finally broken open!

Everyone was also happy, and they drilled through the breach, but when Yan Yu drilled through, the pipe in front began to tighten and became narrow and cramped.

They are even more unable to control their bodies, and they are washed out like flies in a faucet!

"Whoa!"

Yan Yu seemed to have fallen from a waterfall to a deep pool, and when he came up, he found that it was a huge pool, and above his head was a column of rushing water.

They finally made it through the inlet to the reservoir.

There are also several pools next to the water storage tank, which are supposed to be purification pools or something, and it seems that this is the water source of the underground base.

However, there is a man-made dome overhead, and it must have entered the interior of the base.

It is also a loss to risk his life in the pipeline, otherwise the oxygen will not be able to hold up at all, and in this pool, the oxygen will also be exhausted.

Yan Yu They set off in the morning, tossing for a long time, it should be night at this time, and I don't know if the base has rested, or the water storage tank will not be guarded here, at this moment there is no one around, only the sound of water.

Everyone climbed out of the pool, and they were also extremely tired, and they each lay down and gasped for breath to rest.

Zhao Tongyi didn't, he didn't even dare to sit cross-legged, just propped up the pillar by the pool, panting.

Yan Yu knew that he only had this breath left, and once this breath was released, he was afraid that it would be difficult to stand up again, and his heart was also inexplicably sad.

Because of this, Yan Yu didn't rest for too long, stood up and said to everyone: "While the old devils are sleeping, let's hurry up......"

Zhao Tongxuan and the others paid more attention to Zhao Tongxiao's condition than Yan Yu, and they didn't dare to delay any longer, so they stood up one after another, supported Zhao Tongxiao, and continued to move forward.

Zhao Tongyi pushed away the senior brothers, and walked forward for a while, and after coming out of the water source, he said to Yan Yu and the others: "The front is the logistics office of the base, after entering, there should be an old devil guarding it, you must be careful." ”

"According to our previous plan, we must divide the troops into two ways, you go to find Liang Shumei, Haneda Guichen can leave it alone, but Liang Shumei must be rescued......"

He coughed a few times, forced his breath, and continued, "I ...... I have something to do, so you don't have to worry about me. ”

When Yan Yu heard this, his heart suddenly became suspicious, not because he doubted Zhao Tongyi's motives, but because that kind of uneasiness lingered!

"Uncle Shi, tell me honestly, what are you going to do?"

"Don't worry about it, it's too late!"

Yan Yu doesn't eat this: "If you don't say it, we won't leave, I'm afraid of wasting time, so I'll be honest!" ”

Zhao Tongyi also understood Yan Yu's temperament, but he hesitated for a moment, but still said, "I'm going to their treasury...... Just blow up the storehouse and you can destroy it completely!

"Blow up the storeroom!" Yan Yu was also taken aback, because this was underground, and once it exploded, it would indeed be able to bury all the old devils inside, and even the potions they developed, as well as all the equipment, were buried deep underground, and it was impossible for them to leak out.

But this also means that the people who bombed the warehouse must go and never return, which is tantamount to ending up together!

Unless...... Unless they have a delayed detonation device, but the backpack has already been wrenched into the shredder, and everyone's equipment is very simple at this time, there is no way that there really is a delayed detonation device!

No wonder Zhao Tongyi didn't want to stop, let alone let out this breath, from the moment he was rescued, he had already made up his mind to leave himself!

"It's not going to work!" Zhao Tongxuan immediately objected, after all, they had gone through a lot of hardships, wasn't it just to rescue Zhao Tongxuan!

Zhao Tongyi also became serious, and reprimanded loudly: "I'm not dead yet, so it doesn't work if I speak, right!" ”

"Everything else works, this thing just doesn't work!" Zhao Tongxuan also hardened.

Zhao Tong was not verbose, took out an iron plate from his arms, and said loudly to everyone: "Everyone in Dunhuang Mountain listens to the order!" ”

Zhao Tongxuan and others burst into tears, but Zhao Tongxuan walked forward step by step and never looked back!

Yan Yu didn't expect that an iron card would have such a huge deterrent power, and he followed without thinking too much!

He Yan Yan is not a person from Dunhuang Mountain!
