On a moonlit night, the wind was high, and a bird of prey took off from the rooftop and headed straight for the North Sea.

Xiao Xiao stayed at Deep Blue International and took care of the five little phoenixes by the way.

I was going to carry out a reconnaissance mission tonight, and only one Raptor was dispatched, Zixiu, Su Daozhi and Yourou set off together.

When approaching the canopy of the North Sea, Zixiu released his divine power and attracted the wings of the cicada. The cicada wings, light as a feather, ethereal as snow, like a transparent light curtain, float in the night sky.

He flew directly out of the raptor, stepped on the wings of the cicada, and volleyed 10,000 meters into the air.

"Xiao Su, you guys are outside the canopy, wait for a while, and I'll go in to see if it's safe. As he spoke, Zixiu paddled the cicada wings, crossed the 10,000-meter-high canopy prohibition, and entered the Beihai.

The control range of the three quasi-divine powers is about three thousand meters. After entering the North Sea, he locked the direction of Huludao, and traveled all the way against the wind, cutting through the sky, and did not find any abnormalities within the scope of the Shenwei Field.

In early summer, Huludao is full of leaves!

Huludao is made up of two parts, like a round gourd with two sections. The area to the south is larger, about 500 acres.

To the north is a metasequoia woodland, less than a hundred acres of land. Five simple old houses in the forest, experienced a severe cold winter and snow, no one took care of them, and some of them were dilapidated.

After making sure that there was no one in Huludao, Zixiu soared into the sky and returned to the Beihai sky.

"Xiao Su, come with me!"

――――――――――――――――――――

All went well, and the raptor landed on top of a clearing.

Su Daozhi and Yourou walked out together, looking at the deserted island, and their hearts suddenly felt cold.

Zixiu wanted to figure out the current situation of the Beihai No. 3 area as soon as possible, and the detection range of the Shenwei Field was wide, but it was easy to attract detection. Yourou's stealth skills can just come in handy.

"Yourou, thank you for your hard work, in the past two days, I have figured out the current situation of the three regions of Beihai. He laughs.

Yourou nodded: "You can rest assured about this, I'll take care of it, you're busy with you." ”

"The military stronghold is extraordinary, you have to be more careful!" Su Daozhi was a little worried and reminded him.

"I will. With that, with a bang, Yourou transformed into a purple butterfly and disappeared into the night. The entire Beihai District 3 is vast, and for her, it will take at least two days and three nights to investigate.

―――――――――――――――――

After Yourou left, the two of them began to plan the underground fortifications of Huludao.

"Xiao Su, I plan to do a big job in the Beihai Theater, it is not possible to do it without a base, what difficulties do you think need to be overcome in building underground fortifications in this place?"

Building fortifications under the island is easier said than done.

Su Daozhi was a little worried, frowned, and replied: "There is a reef under the island, which is an unstable rock structure, and the integrity is extremely poor. It is almost impossible to carve out space in the middle of the reef. ”

Zixiu thought for a while, nodded, and smiled: "It seems that there is only one way, and that is to hollow out the reef below." Just like assembling a Raptor in the same way as assembling a Raptor in high-quality steel. ”

The casting skills of the raptor are exquisite, and the gaps in the welding are airtight, so the raptor can enter the water.

"Theoretically, yes. Su Daozhi said with emotion: "Completing this task is as good as building a raptor base." The key is that manpower, materials, and equipment must be airlifted from outside. ”

According to Zixiu's assumption, the functions of the underground fortifications cover the personnel shelter space, the material reserve space, and the anti-reconnaissance maneuver space, etc., and the volume is not ordinarily large.

"That's a bit of a struggle!" he shook his head, a little discouraged.

At this time, Su Daozhi reminded: "Brother Xiu, I think there should be other ways to enter Beihai. ”

The ban on the canopy enclosed the Beihai station area in a whole circle, and crossing the canopy became the only way to smuggle Beihai.

"How can I say it, which way else can I go?"

Su Daozhi explained: "Let's put it this way, the Nine Heavens River flows into the Beihai Sea along the Azure Mountain Range, if there is no Tiancanopy, we can completely enter here through the rivers of the Nine Heavens River." As far as I know, the canopy forbade the bottom of the riverbed and jumped 10,000 meters, but it did not enter the ground. ”

"You mean, we can enter the North Sea through the underground passage?" Zixiu figured it out a little, and his expression was full of joy.

"That's right, the Nine Heavens River is just a surface river, and correspondingly, there is also a dark river that flows here from the Azure Mountain Range. ”

Speaking of which, Zixiu completely understands that if he finds this dark river, the problem will be solved.

He thought of a place and said excitedly, "I know, the place where you collected the stone before was the entrance of a dark river!" In a deserted mine near the Five Elements Sect, the flowing water of eight waterfalls converged to form a huge pool.

A striking whirlpool is located in the middle of the deep pool, surrounded by mountains, the water in the deep pool does not flow out of the gap, the water accumulates into an abyss, and the bottom of the deep pool, connected to the dark river, forms a funnel-shaped whirlpool.

"Exactly!" Su Daozhi was overjoyed and said, "The scale of the Dark River is not much different from that of the Nine Heavens River. We could have built a stealth ship to bring the men, equipment, and materials needed to build the fortifications here. ”

Moving forward in the dark river, compared with flying over the Beihai skycanopy, both safety and economy are much improved.

Zi Xiu immediately made a decision, saying, "It's decided, after Yourou returns, we will return to the Five Elements Sect." You're in charge of building the stalkboat, and I'm in charge of drawing the road map of the Dark River. ”

"However, the casting of the stealth ship is still difficult, and I am afraid that it will be too late. ”

"You mean to buy one?"

Xiao Su nodded: "You don't have to buy it, you can borrow it." There is a stealth boat in the Tao family in Azure City, and you are going to meet Tao Feiyan in half a month, so you can mention it. ”

He thought about it, but there was no other good way, and smiled: "Okay then, I'll take care of the stealth boat thing." By the way, how are you going to knock out the reef under Huludao?"

Su Daozhi smiled, looking confident: "This is easy to do, the reef is the foundation of the island, the five elements are the foundation of the world, and my five elements true power can just come in handy." Give me ten days, that's more than enough. ”

"Alright then, I'll help you!"

――――――――――――――――――

For the next two days, Zixiu was in charge of digging the reef beneath the island, starting from the edge and working from the inside out. Su Daozhi's Five Elements True Power was filled in and replaced the reef.

The whole process went on steadily, but Xiao Su had to work harder.

Carrying the weight of the entire gourd island, the consumption of the five elements of true power is not a fraction of it. Fortunately, the spirit stones on the Raptor are abundantly stocked, enough to replenish the real power.

Digging underwater reefs, the Ninth Heavenly Demon Sword is as thin as cicada wings, and sharpening iron like mud.

Under the control of Zixiu's manipulation, the cicada wings are cut in the water as a whole. One by one, the whole brown stone fell off, and the Five Elements True Power quickly replenished it, and so on.

The two of them worked closely together, and the excavation work progressed rapidly, and it took two days and two nights to complete one-third of the entire project.

―――――――――――――――――――

The night was dark and dark.

Zixiu and Su Daozhi were busy, and at this time, a fluttering purple butterfly appeared in front of them.

The butterfly disappeared in an instant, and Yourou appeared, with a tired face, and smiled: "Brother Xiu, I have already investigated the current situation in the three regions of Beihai." ”

He and Xiao Su immediately stopped what they were doing, came back to their senses, put away the cicada wings, and asked eagerly, "How is the situation?"

"In the three regions of the North Sea, most of the troops of the Eastern Continent are gathered on Sifang Island, which is directly south of Huludao, and there are about 300,000 people. You Rou breathed a sigh of relief, and then stated: "The command headquarters has just been formed, and there are a total of eight Martial God-level commanders, one of whom is Tianzhun level. ”

Tianzhun level martial god, things are a little difficult to do.

Zi Xiu took a breath and pondered for a moment: "What is the origin of that Tianzhun Martial God?"

"It is the latest appointment of the goddess Huanning, and her name is Shengtian Yunfei, from the Shengtianmen, the wind system. Beihai No. 3 Theater, he was the commander-in-chief of the front. ”

In the Beihai Forbidden Zone, he peddled spirit stones, risking the world's disapproval.

In case the matter is revealed and there is a flaw, a life-and-death struggle is inevitable. The Ninth Heavenly Demon Sword, under the Tianzhun Martial God, will kill with one blow, but it is not easy to deal with the real Tianzhun Martial God, and there is no complete certainty.

He looked at the silver mark on his wrist, and his expression was like snow: "The matter of Shengtian Yunfei, I'll figure out a way, let's go back first!"

Su Daozhi saw his thoughts and asked, "Brother Xiu, do you want to secretly kill Shengtian Yunfei?"

"Not yet!" he strolled towards the birds of prey, explaining, "We are here to disrupt the situation in the North Sea, and we can not only disrupt the situation, but also control the overall situation at critical moments!"

You Rou nodded and smiled: "Brother Xiu, your current strength, have you broken through the Heavenly Martial God?"

Under the Tianzhun Martial God, one blow will kill, even the ordinary Tianzhun Martial God, there is no such arrogance!

"I'm just borrowing strength, cicada wings are very powerful, I can't do it yet!" he immediately laughed and boarded the bird of prey.
