In summer, wild boars prefer to live close to water sources, especially in subalpine meadows, where wild boars often feed and bathe in muddy waters, where they often eat and bathe. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Therefore, it should be autumn at this time, but it is not yet late autumn, because this group of wild boars can still bathe in muddy water.

also saw this kind of scene, so that Yu Shan determined that the secret realm of the Eastern Wilderness at this time should be autumn.

Some nuts have ripened in autumn, such as acorns, which are the acorns that Tang Baobao said, and Qiu Hibiscus should know this kind of tree, so she will remind Tang Baobao.

Since it is an oak tree, but it has a lot of thorns, it is not ordinary oak.

"Is it thorn oak?" At this time, Yu Shan remembered a legend, because this legend was too wide, so he remembered it immediately.

"By the way, it must be thorn oak, why didn't I think of it." At this time, Qian Xiaohao also recognized it.

"You know thorn oak too?" Yu Shan looked at Qian Xiaohao strangely, this kid just doesn't know how to learn and don't know, how can he know about thorn oak?

"Can you play a game without knowing Thorn Oak? The thorn oak, known as the sacred wood, makes an invincible battleship. Qian Xiaohao said proudly.

Yu Shan could only smile bitterly, he forgot that some time ago, Qian Xiaohao had played a sailing game, it seemed that there were various levels of warships in it, one of which was an invincible battleship, as if it was made of thorn oak.

It was only when he saw the tree that had been struck by a wild boar that he thought of thorn oak, after all, such a sturdy tree is very rare.

Thorn oak is a hard-nosed tree that grows on the outskirts of the city of Roonezh in western Russia, and is known as the sacred tree by the Russians.

In 1696, a fierce naval battle broke out between Russia and Turkey.

A fleet led by Peter the Great of Russia personally launched an attack on the powerful Turkish naval fleet.

The Turks concentrated all their artillery and bombarded the command ships of Peter the Great.

Suddenly, the shells rained down on the deck, but as soon as they touched the hull, they bounced off and fell into the sea, hitting the mast several times, but they were not damaged at all!

The Turkish soldiers were so frightened that they didn't know what was happening.

It turned out that the battleship was made of live Roonezh's sacred wood, a thorny oak with a purple-black surface, which looked ordinary and not surprising at all.

But it is these humble oak trees, whose wood is as hard as steel, and which are not afraid of sea bubbles or fire.

Peter the Great made this miraculous thorn oak a Russian national treasure and sent troops to guard the thorn oak forest day and night.

The inland city of Horoonezh, far from the sea, also went down in history as the "cradle of the Russian navy" because of its production of sacred trees.

In the 70s of the 20th century, Shenmu attracted the attention of Dr. Sergei, a famous forester in the former Soviet Union, for this reason, he used thorn oak planks to fence a large shooting range in the field, and more than 2,000 thorn oak targets were erected in the center of the shooting range.

Sergei fired tens of thousands of bullets at the Shenmu target, but only a few bullets penetrated the target, and most of the bullets were returned by the hard Shenmu target.

He took off a few wood fibers from the target and took them to the microscope to look at, and found that the outside of the wood fibers was covered with a layer of translucent gum secreted by epidermal cells, which hardened when exposed to air, like a layer of hard armor.

The Doctor made a large pool out of thorn oak, filled it with seawater, and threw small pieces of thorn oak of various shapes into it to seal the pool.

After three years, the sealed pool was opened and small wooden blocks were removed.

He was surprised to find that the wooden blocks in the pool were in good shape, and none of them were rotten and deformed, and the wood on the walls and bottom of the pool was also good and undamaged.

This confirms that Shenmu is indeed not afraid of seawater corrosion.

The doctor threw a model of a thorn oak house into the hearth, and the temperature in the furnace was 300C, and an hour later, he opened the door to reveal the model untouched in front of him.

It turns out that the gum secreted by thorn oak can generate a fireproof layer at high temperatures and decompose into a non-combustible gas, which can inhibit the combustion effect of oxygen and slowly extinguish the flame!

The epidermal cells wrapped on the surface of "Shenmu" can secrete translucent gum, which becomes hard armor when it encounters air, and the gum contains copper, chromium, cobalt ions and some chlorides, etc., at a high temperature of 300C, the gum can also become a layer of fireproof, and decomposes into non-combustible gas, which plays a flame retardant role and slowly extinguishes the flame.

The "god" of "Shenmu" turned out to be so, and later, the botanical name of "Shenmu" was named "Oak".

It is because this kind of wood is so amazing, and it has one thing in common with wood such as golden camphor and golden silk nanmu, that is, it contains minerals, so Yu Shan thought of it for the first time.

Golden camphor contains iron, golden silk nanmu contains crystals, and thorn oak is more powerful, containing copper, chromium, cobalt ions and some chlorides, these are special tree species, and only cultivators can collect tree species, and a large area is planted in the secret realm of the Eastern Wilderness.

"This is really a kind of sacred wood, I think, our base, it's good to use this kind of wood as a city wall." At this time, Pang Tong said quietly.

Qian Xiaohao said with a smile: "Then you still need to say, do you know that the battleship made of this thing is super strong in physical defense and magic defense, Shanzi also said just now, the sword is not injured, the bullet is not penetrable, and the cannonballs of the cannon can rebound, which shows that the physical defense is invincible."

And the magic defense is also very strong, ignoring the water magic, the fire defense plus 10,000, the gold defense plus 100,000, and the earth and wood magic absorption, it is simply invincible, no wonder the battleship built with thorn oak is called an invincible battleship. ”

"Okay, it's invincible in the age of sailboats, can it compete with steel warships?" Pang Tong rolled his eyes and said.

"That said, can steel grow? And these can grow. Qian Xiaohao said.

Yu Shan also agreed at this time: "What the mouse said is right, this is a divine tree that can grow, have you noticed, the tall wood here has a common feature, that is, it can absorb a large amount of metal substances."

For example, golden camphor contains iron inside, while thorn oak contains more metals, copper, chromium, cobalt ions and some chlorides, which ensure that their texture is hard, and the hardness explains that they can naturally grow taller. ”

"What about the golden silk nanmu? This wood is softer, as you talked about earlier. Tang Baobao said.

Yu Shan shook his head and said: "Golden silk nanmu is not simple, you may not know, the crystals in the golden silk nanmu are obviously more than ordinary nanmu, the surface of the wood is golden in the sun, and the golden silk emerges, so the golden silk nanmu is a nanmu with gold silk and similar silk luster in some materials, I have cut the golden silk nanmu before, so I know that its hardness is not much worse than the golden camphor." ”

"Maybe you're right, it seems that the sacred trees are not all golden camphor, maybe among the thorn oak and golden silk nanmu, there are also divine trees like that giant golden camphor." The fifth knife interjected at this time.

"Huh? You're done with it? Seeing the Fifth Knife coming over, Yu Shan immediately realized that they were dragging their feet.

"These thorn oaks are really good, they can defend against the impact of fierce beasts, and they can also resist the spells of fierce beasts, and they are definitely the top materials for defense." The Fifth Knife Path.

"Then chop some and make a shield." At this time, Qin Yumo, who had not spoken, spoke for the first time.

Of course, no one objected to his proposal, after all, the characteristics of thorn oak are still very reassuring.

"If you want wood, you have to drive this herd of wild boars away, this place is good, we can attack three targets at the same time." Zhao Tongwu also walked over, and he glanced at the pod hidden between the trees.

The airship is on the top of the tree, and the survey can descend into the bushes so that you can accurately grasp the wild boar herd in the woods.

"If we attack with spider claws, we can actually attack ten prey at once." Qian Xiaohao proposed at this time.

Yu Shan glanced at Qian Xiaohao and said: "I, Xiaodao, and Huang Da are three dark energy periods, and there are six of them at the peak of Ming Jin, and the others are at most Pang Tong, but can you be sure that one blow is fatal?" You know, spider claws are not easy to handle. ”

"Hehe, we haven't eaten rice in Tianyuan Valley recently, we are shooting rabbits and catching pheasants, all of them are training our reflexes, and now there is no difficulty in throwing a javelin." Pang Tong said with a smile.

"Since this is the case, then except for Mi Xiaoyong, Tang Baobao and Qiu Furong, we will each lock on a target, don't worry, I will watch you, as long as anyone makes a mistake, I will make up for you, come, assign weapons, lock on to the target, don't overlap the target." Yu Shan only thought about it for a while, and then agreed to Qian Xiaohao's proposal.

On the one hand, it is unlikely that the wild boar will run away with the spider's claws, and on the other hand, it will make Qian Xiaohao and them increase their sense of achievement.

"Then let's also increase the difficulty a little, just use bone beads, so that we can also lose a little essence and blood." At this time, Huang Dao.

Of course, the fifth sword will not object, although he has not been in the dark strength period for a long time, but with Yu Shan's help, his cultivation has improved recently, so it is not weaker than Huang Dalai.

Each assigned a target, got the spider claws, and all prepared to attack.

The order to attack was given by Tang Baobao, and after she gave the order, Yu Shan reacted the fastest and immediately projected a bone bead.

When the bone bead hit a huge wild boar, the spider claws of the others whistled and flew out, and at this time, Yu Shan was ready for a second attack.

Seeing that there was still time, Yu Shan once again locked onto a stunned wild boar and threw his own bone beads, and Pang Tong, who reacted the least, had just thrown a spider claw. (To be continued.) )
