"A city?" Tian Xuanyang lowered his eyebrows and felt incredible. So, he hunched over and walked into the barrier to see for himself.

Since the glass plate is recessed, the space is vacated in both left and right directions. After Tianxuan entered, the reconnaissance team was divided into two rows, left and right, and followed in.

After entering the barrier, they were completely stunned by the scene in front of them, where is this stronghold? It's just a bustling city.

The scout team looked around and saw that the city's light depended entirely on the glowing plants in front of the valley, and its interior was rather dim.

So, after some exploration, Tianxuan basically determined that this was a replica of the shape similar to Brentle: a city with a ring and a radioactive road. However, there is something different about this radioactive road, which is an artificial waterway flowing with azure water.

Tianxuan looked down at the flowing sea water in these artificial waterways and wondered.

"What are you thinking?" Hercules asked.

So Tianxuan pointed to the artificial waterway that ran through the ring road and said, "Hercules, have you seen it, there are Styx rivers all around here, but these artificial waterways that run through various parts of the city are all flowing with azure water, it should be seawater!" Anyway, I haven't seen blue crude oil. ”

"What do you want to say?" Hercules asked again.

"Do you Maya have the technology to open a factory next to crude oil and not need fire protection?"

Hercules shook his head and said, "No, unheard of!" ”

"Then here's the problem, look there." Tianxuan said and pointed to the factories that were running near the waterway, "Even if it's blue crude oil, you see that these factories are basically built on water, if it was crude oil, wouldn't it have caught fire and exploded a long time ago?" ”

Hercules looked in the direction Tengen was pointing and found that many factories were built beside the blue waterways, as he had said. Then his eyes widened, and it dawned on him, "I see, the blue liquid flowing in these waterways is seawater, and this is the water that trench ronins must drink. ”

Tianxuan glanced at the people below and said, "Then let's take a closer look!" Let's check if it's seawater! ”

"Order!"

Then the 100-man reconnaissance team crept closer to the waterway, wandering like ghosts in the dimly lit city.

About 30 meters away from the waterway, there was a sudden "bang" sound.

"What sound? There are enemies! Hercules immediately stopped. When everyone heard Hercules' warning, they hurriedly stood in place and were fully armed. But after a while, they only heard a faint "bang-la-la" sound, but there was no movement.

Just when everyone was at a loss, Tianxuan covered his ears with his hands, leaned sideways and listened carefully to the sound of "bang-la

In order to verify his point, Tianxuan immediately lay on the ground, leaning sideways and pressing his ears to the ground.

According to the records in "Dream Creek Writings", if the enemy is coming, because the ground will vibrate because of non-stop walking or running, the sound will have some continuous and gradually increasing "boom" sound. This is not the case now, neither sustained nor intensified, but rather the sound of the water crashing on the shore.

However, due to the unfamiliar environment at present, there may be dangers everywhere, Tianxuan lay on the ground for a while, and finally believed in the sound of the seawater, so he breathed a sigh of relief, slowly got up and dusted his body with his hands.

Looking at Tianxuan's relaxed face, Hercules couldn't help but ask, "Did you find anything?" It doesn't feel like you're nervous at all! ”

Tianxuan smiled and told Hercules and the others: "Don't panic, everyone, I have determined that the noise we heard was not the enemy attacking, but the sound of the water crashing on the shore. ”

"Oh, it's not an enemy, Shiro has been nervous for a long time!" Hercules said with a long sigh of relief. Then, the others lowered their hands holding their weapons.

After everyone gasped for a while, Tianxuan ordered: "Keep going!" So the people continued to draw near to the waterway under his leadership. The distance of 30 meters passed in the blink of an eye, and they soon came to the shore of the waterway.

With the faint light coming from around the valley, it took Tianxuan about a few minutes to see the structure of the waterway. It is a W-shaped three-way waterway: the middle channel extends from a distant place and goes all the way downstream; Then, when it reaches the shore of the W shape, it diverges and flows back to both sides. This structure is very cleverly designed, so that the waterway on both sides has almost no attenuation of speed upstream.

Just as Tengen's design for this waterway attracted him to approach slowly, there was a faint vibration under his feet. Seeing this, Hercules rushed forward and quickly pulled him back.

There's nothing wrong with being too careful, but the shaking just now is indeed their fuss, and after Tianxuan was pulled back by Hercules, he found that there was a grit tank below the place where the vibration just now was used, which was used to regularly remove the precipitated sand.

"I'm scared to death baby!" Tianxuan stroked his heart with his hand and said with a long sigh of relief.

"Sorry, excited again!" Hercules said with a drooping face.

Tianxuan shook his head, waved his hand and said, "No, Hercules, you're not wrong, it's just that a lot of things are too magical" Then he looked at the beach on the grit pool again, and found that the beach was full of fine grains of white sand, and he stepped on the soft feeling with his foot.

"Judging from the state of the beach, it must have been formed by the sea hitting the shore." Tianxuan touched his chin and muttered to himself.

"Why are you so sure?" Hercules asked.

Tianxuan raised his head slightly and held his chin and said, "You see, if it's crude oil, the sediment can't be so loose. ”

"How so?"

"Most of the sediment of crude oil is paraffin, which is also white, but it is not so loose; If it is offshore oil, the precipitation should be asphalt, which is in the form of black colloids. So from all sides, there is sea water flowing in this waterway. ”

"I see!" Hercules nodded in understanding.

Then, Tianxuan walked to the water's edge and squatted down and said, "Let's take some water and come up!" Then he put his hand into the water, filled it with a little water in his palm, and then got up and came out to the crowd with his arms flat.

"Sure enough, it's sea!" Everyone said in unison.

"Where is this endless stream of water coming from this valley that is all over the River Styx, and where is the valley so flat?" Hercules asked as he looked at Tianxuan's palm.

"Good question!" Tianxuan nodded and continued: "Since there is a continuous flow of seawater water, there must be a source. But there's definitely no seawater underground! ”

"Could it be that they brought it from near Lanmian City?" Hercules asked, frowning.

Tianxuan shook his head and replied, "Who knows? We will go up the waterway and believe that the results will be soon. ”

"That's right, then what are you waiting for, let's go! This thing has aroused my curiosity, and I can't swallow this breath if I don't figure it out! Hercules said, crossing his waist.

"Breath?" Tianxuan tilted his head and looked at Hercules with wide eyes.

"Eh" Hercules knew that Tianxuan was ridiculing himself, gave him a blank look, took a few steps forward, and then said without looking back: "Let's go, don't rub it off!" ”
