It wasn't until the second half of the night that He Yingwu and his entourage arrived at Wenyuan Valley.

After Song Liancheng confirmed the location, he quietly cut a hole, gently pushed away the thick ice floe, and crawled out like a zombie.

Six people, six frozen dogs, six ice mounds......

It took a little shorter than they expected, only about six hours to arrive, Song Liancheng was like a goose, not only guiding the shortest distance and safest route, but also breaking through most of the water resistance, and the people behind him were one by one, much easier.

However, the temperature under the sea is much lower than they expected!

He Yingwu and Song Liancheng are okay, after all, the strength is there, but Yan Qiaoliu, Su Shishi, Qian Shutong, and Jiang Sidu almost didn't freeze to death......

Climbed ashore, found a place to hide, and after a long time, he finally eased up.

Taking advantage of this gap, He Yingwu cleaned up the traces of their group.

Song Liancheng took out the layout map, confirmed the location, and quietly climbed a few laps in a radius of dozens of meters around, and finally selected a place, beckoned everyone to gather, and said in a low voice: "Start digging down from here, tilting 60 degrees to the ground, and the direction is here." ”

He said as he straightened his left arm, aiming at the very center of the island, where the Wenyuan Valley was located.

"Good!"

"One space ring for one person, the earth and stones dug up will be put into the ring first, and then scattered in the sea when we retreat, understand?"

"Understood!" Everyone took the space ring one by one, but a position flashed out, "Please take the initiative to take the first step." ”

He Yingwu did not shirk, and between the movements, the broken arrow suddenly came out, and with the vitality wrapped, he forcibly pry a large circle with a diameter of about four meters.

He lifted it up slightly, and the cylinder he pulled out was about a meter high.

"From the center point, two meters in diameter, dig diagonally down!" he said.

In this way, a cylinder with a height of one meter and a diameter of four meters can be made into a lid.

"Good!"

They quickly dug out a place to stay, and He Yingwu gently covered the "lid".

After that, it was Song Liancheng who judged the direction and carefully identified whether there were mined veins in front of him, while the others were wielding fairy swords and constantly digging tunnels.

According to the requirements of what should be done, it is a spacious enough tunnel.

The fairy sword did this job a little wronged, but the fairy sword that blessed the molecular dismantling force field is really good!

......

After digging for a long time and estimating the time, it was already dark before dawn.

They stopped and quietly figured out the tunnel, Song Liancheng took the lead in case of an emergency, and he should wipe out all traces after the matter was broken.

Quietly entering the water in turn, they went straight to Sun Moon Island, Song Liancheng quietly cut a circle with a diameter of one meter, He Yingwu gently pushed away the ice floe and climbed out, leaving a little trace, and dived into the water again.

After that, he made a gesture, and everyone took out the earth and stone that was digging the tunnel from the spatial ring and scattered it into the sea.

Not to mention Su Shishi and the other four, even Song Liancheng admired it to death, the sect master's ability to frame people is really ...... Thoughtful and seamless!

This is the suzerain, not the enemy......

By the time they had dived back to Shake Light Island, the sun was already high.

Everyone is covered in seawater, and they will turn into ice when they take a few steps, or Jiang Sidu is smart, he learned to be like a dog and shook violently, shook off most of the water, and threw others off.

Song Liancheng's face was a little pale: "Sect Master, there are sharks and whales in the sea, using their skins to make waterproof clothing, it should be very warm and waterproof, and it can reduce the resistance and increase the speed! Why don't I go into the water today?"

I also think that on this trip back and forth, people will freeze to death, and they will not have the strength to dig tunnels. In this way, shark skin and whale skin on the outside and hair on the inside, it should be much better to make it completely airtight and waterproof!" He Yingwu said.

"yes, yes! That's what I think. ”

"There is also the issue of speed, one is what Elder Song said, and the second is that I have some ideas for underwater boosters, and if I improve them a little, it may be faster. In addition, according to the volume, it should not be a problem to tie two sets of boosters to each person, and the speed can be faster! It would be good to control the one-way time to three hours. ”

"Okay! The sect master will notify me at any time if there is any progress, and I will fully cooperate!"

"Hmm!"

......

By the evening, six tightly sealed thick-haired shark suits had been made, and twelve improved underwater boosters had been forged.

Song Liancheng gave each person another space ring: "Two space rings are enough to hold the soil and stones you dug up." Today may be more abundant than yesterday, everyone should be quicker, if according to yesterday's speed, we can't catch up with the tenth day of the lunar month, everything is in vain!"

"Yes!" After resting all day, Su Zhishi, Yan Qiaoliu and the other four were already full of energy and ready to move.

Psychologically speaking, the four of them were brushed down from the speed running group, and deep down, they were afraid that they would really become waste and pull the sect back.

After all...... Not everyone can be as psychologically strong as Cui Dapeng, without pressure, and happy to raise pigs......

The operation process has not changed much, or Song Liancheng led the dive gallop, quietly cut the ice, sneaked up to Wenyuan Valley Island, opened the lid and went underground, he judged the direction, and everyone continued to dig the tunnel.

When it was about to dawn, he called it a day in time, dived to the edge of Sun Moon Island, cut through the ice, left a little trace, and then scattered soil and rocks in the sea, and finally dived back to Shaguang Island.

Frankly speaking, the whole trip was much more comfortable because of the thick shark suit.

However, Uncle Qian couldn't figure it out a little: "Sect Master, Elder Song, let's sneak over at one time, bring enough drinking water and dry food, and keep digging day and night, we can definitely catch up with the progress! We don't have to run back and forth every day, it will take seven hours on the road!"

He Yingwu and Song Liancheng glanced at each other and smiled.

"Digging during the day? Do you think Wen Yuan Ancestor eats dry rice? Don't challenge the perception of the old monster. Song Liancheng shook his head and said.

"That'...... So what if we don't dig during the day, just lurk and dig at night? Uncle Qian thought for a while and said.

Song Liancheng paced back and forth for two steps, looked at Su Zhishi, Jiang Sidu, and Yan Qiaoliu, paused, and asked, "What do you think?"

A few people looked at each other and said, "We think...... What Shu Tong said makes sense. ”

"I also think it makes sense!" Song Liancheng suddenly smiled and nodded, "Imagine a situation, if the people of the Sun Moon Gate want to do this and dig tunnels, what will they do?"

"They...... Close, it should be dug at night and retreat at dawn. Because they are relatively risky to stay in the tunnel during the day, and the cost of returning to the Sun Moon Gate is very small, only a few kilometers of diving. Uncle Qian frowned slightly, thoughtful.

"So what?" Song Liancheng looked at Su Shishi.

"So...... If it is a tunnel dug by the Sun Moon Gate, there will be no traces of long-term life in the tunnel, and there will be no flavors produced by long-term life, such as food and so on!" Su Zhishi said.

"Hmm, and then?" Song Liancheng looked at Yan Qiaoliu.

Biting his lip, Yan Qiaoliu's eyes burned: "We have two considerations, first, to dig a tunnel to the secret room before the tenth day of the lunar month; second, if we can plant the Sun and Moon Gate by the way, then it is the best! According to the progress after the adjustment, we should be able to take care of both!"

"Hmm, what's the conclusion?" Song Liancheng finally looked at Jiang Sidu.

"The conclusion is that from the perspective of the Sun and Moon Gate, the safest way to do this is to turn back and forth! Although it is very likely that no one will notice the traces and smells of long-term life, if it is impossible to do anything, and if you really go to the last step, in the eyes of a real master, these subtleties will surface! No one will be stupid enough to sneak more than 600 kilometers to dig a hole and turn back every day! And this is also the blind spot of people's thinking!" Jiang Sidu nodded as he spoke, and the more he spoke, the clearer it became.

"Well, this stupid decision is a joint discussion, don't blame me, and don't blame the sect master. Song Liancheng smiled.

Jiang Sidu and the others were slightly stunned, and bowed deeply: "Elder Xie Song solves his doubts! Sect Master Xie taught!"

In the past, but there has never been, never, and never such a situation, it was the elders and the sect master who made a decision and it was over, how could it be like today, still being kind and careful to analyze!

The thought process of this decision is more helpful to several people than the specific conclusion.

It all starts with the way you think.

......

Seeing a few people go back to rest, He Yingwu patted Song Liancheng on the shoulder: "Thank you Elder Song for putting all this effort into cultivating them!"

Song Liancheng smiled bitterly and bent over: "In the chest of the sect master, the sea of stars, Liancheng can't think of it, and he can't see the top! These days, he is even more confused, I am afraid that my skills are low, and I can't help the sect master for a single star! I can only do my best to teach the young people, hoping that one or two of them can keep up with the pace of the sect master, then Liancheng ...... I was able to smile with relief. ”

He Yingwu was slightly stunned, and then laughed out loud: "Elder Song is so cranky! I think you don't have much work! Have you done the blueprint of the secret room? Come on, I still need Elder Song's help with more than a dozen things......

A dozen things?

I'm going to die!

Song Liancheng's eyes widened, his face was full of confusion, and he hurriedly interrupted: "The matter of the blueprint of the secret room, the appointment is today, please rest assured that the sect master!

As he spoke, he bent down and took a few steps back, didn't dare to say more, and walked away......
