After a headache all night, Fang Wuxian couldn't think of any way to crack the formation. However, he believes that hard work pays off, and as long as he moves forward, there will always be a time when the clouds open and the moon shines. Therefore, the next morning, he woke up again to make breakfast, and then the three of them continued on their way.

"This formation is different from the dense fog array outside the Yunshan Ancient Site. In the dense fog array of Yunshan Mountain, the existence of the anomaly can be clearly felt, but here, the sky is high and the earth is wide, and it is impossible to detect anything wrong. It looks a little smarter than the Cloud Mountain Dense Fog Array. There is no danger for us to walk here, I believe that the people who set up the formation have no obvious malice, I think, today we will not go forward, but backwards, if we can exit the big formation, see if we can bypass the past. ”

Fang Wuxian suggested this, but Su Yan disagreed. The induction between her and Su Fei was not too strong, if she retreated, even if she could withdraw from the big formation, there was no guarantee that she would be able to find the route Su Fei had taken after the detour. Moreover, since this is a formation, who can guarantee that Su Fei and the others will pass through the big formation instead of still being trapped somewhere in the big array?

Su Yan's consideration is not unreasonable, it stands to reason that Su Fei and Chen Shuwen have been in the mountain for a few months, and there was news from time to time at the beginning, but there has been no news at all recently, if they are trapped in a certain place in the big array, it is not impossible.

The two finally decided to continue to follow the route Su Fei had taken, not to crack the big array, but to find Su Fei and their traces.

This time they traveled in a different way than yesterday, no longer walking into the evening in one breath, but only walking more than twenty kilometers, and then found a sheltered place and stopped. According to Fang Wuxie's guess, if he went to the evening and then returned to the original point, then the day's time would be wasted. It is better to walk a distance first, take a look at the situation, and then take this time to rest and prepare for a protracted battle.

Because I don't know how long I will be trapped by the big array along Su Fei's route, and if I really get trapped, what kind of situation it will be. Therefore, the thing to do when resting seems to be to prepare food, and in this snow-capped mountain, the most common food is meat.

Xiaobai is very interested in storing food, to be precise, in the fire that the other party has set up innocently. Knowing that it was going to roast again, it jumped happily and ran off to hunt.

Su Yan shouted in the back, "Xiaobai, the kind you ate last night, cow, moo......"

This white ape is full of spirituality, and two voices are considered to be a response. was running happily, when suddenly his feet slipped, and his huge body flew out. Fortunately, it was agile, screamed twice, flipped in the air, and staggered to the ground.

Su Yan giggled when he saw this, and Xiaobai lowered his head a little shyly, and also laughed.

This harmonious scene makes people's hearts warm. Fang Wuxian laughed while collecting firewood, and accidentally slipped under his feet, and fell on his head.

This completely made Su Yan and Xiaobai laugh, and the camp was full of cheerful laughter for a while.

Fang Wuxian lay on his back in the snow,

Fang Wuxian turned back to her and smiled: "I remembered the toy I had when I was a child, make one for you." Seeing the cold wind blowing the tree branches, I suddenly had an idea in my heart, and a carp stood up, pulled out a pig-killing knife, and slashed forward.

With a bang, an arm-thick pine tree was cut off by him, and the laughter behind it burst out. Su Yan thought something was wrong, but after a few seconds, he saw that nothing happened, and said, "You are nervous, what kind of tree do you have nothing to do?" ”

Xiaobai, go hunting, remember, don't want brown bears, that thing is too fat, I want yaks, the kind I ate last night. ”

Xiaobai nodded, ran into the wind and snow, and soon disappeared.

Su Yan wondered: "Do you still do carpentry work?" What toys to do. ”

"Just wait and see."

Fang Wuxian was in the middle of the day, and he already had a sketch in his heart, the pig-killing knife flew up and down, chopping, chopping, chopping, and chopping all kinds of techniques flowed smoothly, and the branches and bark were scattered in all directions, and soon a pine tree was completely dismembered by him, becoming a stick and a board.

"Do you know what I'm going to do now?" Fang Wuxian asked.

Su Yan understood a little at this time, but looked at Fang Wuxian cutting off the yards, and was a little puzzled: "Are you going to make skis?" But even if you count Xiaobai, there are only three of you, why are you making so many pieces? ”

"You're half right. It's just that I'm not just going to do skis. Fang Wuxian picked out six boards of about one meter and six round wooden sticks and put them aside, pointed to another pile of wood and said, "For the rest, I will make you a commonly used means of transportation in our Northeast, the snow climbing plow!" ”

Su Yan said: "When I haven't seen a snow plow? We don't have nails, and skis can be tied to our feet with ropes, but you can't use a rope to tie out a snow climbing plow! ”

Fang Wuxian smiled: "You don't know this, in our Huaxia, there is an ancient skill, called the mortise and tenon technique, and you don't need nails to connect wood!" This technique is the soul of Chinese architecture, not to mention the core of ancient architecture. ”

"No nails?" Su Yan's eyes flickered, and he suddenly realized: "I remember, it is said that the Forbidden City in Yanjing did not use a nail." Well, it seems that there is still some kind of tower, and not a single nail has been used. ”

"As the saying goes, Cangzhou Lion Yingzhou Tower, Zhengding Bodhisattva Zhaozhou Bridge, these are all treasures of China, you must be Yingzhou Tower. The tower is nearly 70 meters high, with about 26,700 tons of wood, and its core skill is mortise and tenon. The ancients could build such a large building without nails, and I couldn't have made a snow plow with this technique. ”

"So, you really know how to do carpentry?"

Fang Wuxian quipped: "Could it be that I will tell you that in fact, I studied under Lu Ban and was originally a carpenter?" ”

"Cut!" Su Yan glanced at him, squatted down and picked up two pieces of wood, and couldn't figure out how to connect them without nails for a long time, so he threw the wood squares in annoyance, and hummed: "Little carpenter, show this girl how to use nails." ”

"Okay, you're good to go!"

Fang Wuxian sat on the wooden stake and began to make the knife, talking while making, using wedge nails and tenons here and zongjiao tenons there, and finally making all kinds of small squares into all kinds of strange shapes.

Although it is no longer the original wooden square, there are as many as 100 large and small parts, and the shadow of the snow plow cannot be seen at all.

"In our northeast, we generally bend wood as a wheel, and then nail a crossbar, even if it is made into a simple climbing plow. But now it is inconvenient, there are no nails, and it is neither beautiful nor easy to warp pine wood. Therefore, I will use the mortise and tenon technique to connect the wood, and use the bucket arch structure to make the wheel, you wait for a while, and it will be done. ”

Fang Wuxian put away the pig-killing knife, picked up the parts one by one, connected them like building blocks, and soon put all the parts together, a snow climbing plow that Su Yan had never seen before was half completed.

(Actually, the sound of the yak is not mooing, but somewhat like a pig, also known as a pig sound cow.) ）
