Sometimes the progress of civilization does not require too advanced technology, and occasionally a flash of inspiration can solve a big problem, just like determining the direction of a big tree when cutting wood, Shen Long knows more than one solution.

For example, you can first let people climb to the top of the tree with a rope and tie the treetop with a rope, as long as the length of the rope is more than twice the length of the tree, and let people pull the rope hard at the right time, you can ensure that the tree wants it to fall that way, and there is absolutely no need to worry about accidents.

However, this method is a little troublesome, Shen Long planned to use a simpler method, but he did not rush to cut down the tree first, but first went to the stump that was cut down just now, waved the axe to cut down a piece of wood, and processed it a little more to make a wooden wedge that was thin in the front and thick in the back.

Then borrow a large saw, cut to one-third of the diameter of the tree on the side near the bottom of the mountain, take out the saw and then obliquely saw it down above the horizontal saw mouth to form a "V" gap, then turn to the side near the mountain, use the saw to horizontally sawed out a saw gap of no more than a quarter of the diameter, and then drive the wedge that has just been made into the saw seam, and use the back of the axe to beat the wedge while sawing, and when it feels about the same, pull out the saw, and finally hit the wooden wedge hard.

When the guys in Kiba saw Shen Long's behavior like this, they couldn't figure out what he was going to do, and they watched the excitement on the side, the old one-armed man had been in Kiba for many years, and he vaguely saw some doorways, scolded twice to shut up these people, and then watched Shen Long's movements without blinking.

"Fall down the mountain~~~" With Shen Long's shout, the big tree hugged by one person really fell down the mountain according to Shen Long's shout, and the surrounding onlookers were motionless, and it had no impact at all.

This is the wood wedge positioning method in the logging skills, which can ensure that the tree falls in the opposite direction of the wooden wedge, the previous one is called the rope control method, and there is a method called the jack inverted method, which is similar to the wooden wedge positioning method, the only difference is to see out the rectangular gap behind the tree that can just put down the jack, and then use the jack to top the tree in the planned direction.

The rope control method is not good for trees that are too thick, and they definitely don't have the old one-armed jack, so Shen Long took out the wooden wedge positioning method, which he saw in a movie, but he didn't expect it to come in handy here.

"This way...... Seems to work! When the dust from the tree fell to the ground settled, the guys in the woodyard began to talk about it.

"Yes, if we learn this hand, we won't have to worry about cutting wood in the future." Someone chimed in.

The old one-armed man rushed to Shen Long in three steps and two steps, grabbed his arm and asked urgently, "Big brother, where did you learn this method?" ”

"I saw it in a broken book, but I didn't remember it before, but when I saw you cutting down trees, I suddenly remembered it." Shen Long casually made an excuse.

"You can even read? There's even this stuff in the book? The old one-armed man was amazed.

There are more useful things in the book, and how to build a chain saw that can turn by itself, and even a way to make a large logging machine, a car drives to the edge of a big tree, the mechanical claw reaches over to hoop the roots of the big tree, and then in a few minutes you can cut a big tree, clear the branches and leaves, and sawed off the treetops into rough logs, which is countless times more efficient than you.

After being surprised, the old one-armed begged Shen Long, "Big brother, it stands to reason that this is the craft you learned, I really shouldn't say this, but every year in our mountain farm, many people are stoned to death by big trees, if you learn your hand, the big guy doesn't have to worry about being smashed into meat puree." ”

"Come here, come here for me." The old one-armed man is a person who talks about the rules, and he can't do anything to learn from others, so he beckoned all the Kiba guys together, "Kneel down with me, kowtow to the Zhu brothers, and beg him to teach us our skills." ”

No matter what these people thought of Shen Long yesterday, the hand he just showed was really life-saving, and he knelt down in the snow for Shen Long without saying a word.

Shen Long hurriedly stopped the old one-armed, "Big guy, hurry up, uncle, aren't you breaking my life?" How old am I to be able to afford such a heavy courtesy? ”

"With this kung fu that goes down the mountain, even if it is a ringing head, you can afford it, this may be an occasional sentence in the book for you, but for the old and young masters in our wooden yard, it is a life-saving means." The old one-armed man still had to kneel down for Shen Long, but he couldn't earn Shen Long.

"You kindly took me in yesterday, which is equivalent to saving my life, this little trick, if you want to learn, I will teach you now." Shen Long just wanted to have a good relationship with the old one-armed, but he didn't expect such a big reaction from the other party.

He forgot a little, now is not the next generation, if you want to learn something, as long as you search on the Internet, it is almost inseparable, at this time, the big guy wants to learn some craft, it is very difficult, don't look at this is such an inconspicuous thing, many people regard it as the ability to take care of the house, pass on the male but not the female, even if you have to accept an apprentice, you often leave the trick before you die.

There were even more ways to test and oppress apprentices before, but no one would easily hand over such a useful thing.

Shen Long finally stopped them from kowtowing, helped the big guy up, found a big tree, and taught the old one-armed them the trick of the wooden wedge positioning method word by word.

To put it bluntly, this thing is very simple, it is nothing more than the ratio of two saw edges, plus a few wooden wedges, the old one-armed man has been in this line of work for so long, and he can get through it at all.

"Wet wood is not suitable for this wedge, it is better to use hardwood that is dry, so it is best." Shen Long nodded.

"Well, it's this reason, wet wood is not as strong as dry hardwood, there is nothing else in our mountain farm, there is a lot of wood." The old one-armed nodded in response, "I remember that there are still a few good ironwoods, and I will go back at night and work hard to saw a few more wooden wedges out, and the big brother will help us palm our eyes to see how many saws are of the right size." ”

Tsk, that's what Ironwood is used for this? It's too extravagant, right? Shen Long grinned and didn't know what to say.

"Brother Zhu, you are the great benefactor of our wood farm, don't say anything, don't be in a hurry to cut wood today, go around for me, and find some flying dragon birds and lion's mane mushrooms for Brother Zhu to try." The old one-armed man doesn't even do serious work anymore.

"I didn't say it, I saw one behind the mountain a few days ago, and I shouldn't have run far yet." The guys in Kiba responded in unison, dropped their axes and saws, and disappeared into the depths of the jungle to find something to eat for Shen Long, a great benefactor.
