"Why is patina?," Wang Jinbao just asked, and thought of his high school knowledge.

Copper rust will be divided into several stages, copper will first slowly oxidize to form cuprous oxide, and the color of cuprous oxide is red!

The reason why Wang Jinbao was puzzled was because the patina was all green, and he had never seen the red patina, so how could it be oxidized to the first step and stop......

The old man walked towards the village, "What's wrong with the red ones, does it have to be green?

Wang Jinbao hurriedly followed, green? It seems that some of his scientific knowledge is also useful in the flood wilderness, for example, listening to this old Taoist tone, the patina in the flood wilderness should generally be green.

Wang Jinbao followed Lao Dao to the village chief's uncle's hut, and Lao Dao shouted into the house:

"Old man, come out, I have something to ask you. ”

Wang Jinbao was speechless, I'm afraid you are older than the village chief and uncle, and you are still called an old man?

The village chief walked out slowly, vigilantly looked at the old man in a tattered robe, and then looked at Wang Jinbao, Wang Jinbao trotted over, and explained to him, the village chief and uncle let down his vigilance and smiled at the old man:

"Dao Chief, I don't know what's the problem?"

"Where did you get this broken iron sheet?"

Wang Jinbao rolled his eyes for a while, wouldn't this be an unimaginable treasure?

"This ......," the village chief seemed to hesitate.

After a while, the village chief sighed, "That's it, I'll tell you." ”

Lao Dao played with the patina, nodded slightly, and showed a satisfied smile.

The village chief made it on the stone next to the hut, and his eyes showed a look of memory,

"It was when I was young, I had been out for a few years, and I had three or five friends, and once, we entered a secret ......"

"And just like that, I was the only one who was saved by being near this scrap of iron, and everyone else died there. ”

The village chief's face was gloomy, and it was obvious that he still had pain in his heart to this day.

And Wang Jinbao didn't expect the village chief's past to be so wonderful and high-spirited, according to the village chief's uncle, at that time, he was in the Dao Foundation Realm, above the Breaking Sea Realm, even more powerful than Lin Lei!

It's a pity that because the expedition hurt the foundation, he luckily didn't die, but his martial arts were also destroyed.

If you think about it carefully, the energy that even the Dao Foundation Realm can't resist is blocked by this piece of patina, this patina is so powerful?! Or is it just rust?

Sure enough, it's an unimaginable treasure!

Wang Jinbao stared at the piece of patina in Lao Dao's hand with fiery eyes, with it, even the attack of the Dao Foundation Realm could be blocked!

Lao Dao glanced at Wang Jinbao, and the corners of his mouth twitched.

He touched his wide sleeves and threw an object at the village chief, Wang Jinbao caught it, and after a closer look, it was a crystal clear tiger talisman, the whole body was translucent, flashing with colorful light in the sun, and a faint halo emanated, and it was not an ordinary thing at first glance.

"This tiger talisman is a formation, which can be turned into a large defensive array to protect your village, and it can also be transformed into a tiger, and the enemy who breaks the sea realm can also fight, so it should be used to exchange for this piece of scrap iron. ”

The voice of the old Taoist came, Wang Jinbao's face suddenly darkened, and before he could speak, he heard the village chief uncle:

"I can't help it, Dao Chief, this treasure is too valuable. ”

Wang Jinbao: ......

Co-author has always said that scrap iron sheet is set here?

Wang Jinbao hugged the village chief and uncle, walked back to the house, and whispered:

"Uncle, that piece of scrap iron is so powerful! Do you think, he was able to save you from the Dao Foundation Realm at the beginning, and the power is unfathomable!"

The village chief smiled: "Jinbao, do you think I have lived in vain for so many years? Of course I know that it is not an ordinary piece of scrap iron.

But people have to learn to judge the situation, and it's good that he didn't snatch it directly. ”

Looking at the village chief's uncle's rickety back and cloudy old eyes, Wang Jinbao suddenly remembered a sentence, your uncle is still your uncle......

However, the village chief didn't know his relationship with this old man, thinking that this old man was a master invited back by Wang Jinbao, but he couldn't just forget it, just rushed to the excited heart of the old man just now, and his trembling hands, he had to order it again!

Wang Jinbao walked outside, pulled the old way, and walked into the distance,

"You are polite to me, Dao Master, my precious Taoist robe is something you can pull?"

Wang Jinbao looked at the dirty and torn robe in his hand, let go of his hand, and was speechless for a while,

"You're picking up a big bargain, no, you have to come up with some more, just take out some kind of panacea, treasure scriptures. ”

Lao Dao almost got angry when he heard this, when he was a cornucopia or what?!

The two pulled and pulled, and the war of words went back and forth, and finally took a step back from the old way, and took out a tiger talisman to end up, mainly because Wang Jinbao used a killer weapon, and if he didn't give it, he wouldn't do it!

Old-fashioned, make up your mind, the matter is over, no matter whether it is successful or not, just beat this goods, he has not suffered this grievance!

If it weren't for maintaining a good demeanor and not doing those things that are difficult for strong people, your kid would have died a long time ago!

These two tiger runes are a pair, they are twin large arrays, they can absorb and store spiritual energy by themselves, and they can improve the concentration of spiritual energy in the array without fighting in normal times, and they can quickly recover their spiritual energy when fighting, almost self-sufficient.

What's more, this twin array can transform two giant tigers, and even the Dao Foundation Realm can fight!

Before, Lao Dao was reluctant to give them all, so he kept one, which turned his head with a black face and stopped looking at Wang Jinbao.

Wang Jinbao left the tiger talisman to the village chief, this treasure is of great use to Xiaohao Village, in case of a powerful beast or something, there is still a bit of defense, and even a giant tiger can fight back,

Even if there is no danger, it can be used to improve the concentration of spiritual energy, which is also of great benefit to the villagers and can prolong their lives.

The village chief naturally shirked with Wang Jinbao, saying that Wang Jinbao was dangerous outside and needed treasures, but he couldn't resist Wang Jinbao and had to accept it.

After doing this, Wang Jinbao returned to the old road, said hello, and wanted to see the villagers.

"Give you two hours! Enough!" said the old man's angry voice,

"Enough, enough. ”

Two hours later, Wang Jinbao visited each of them, and received warm hospitality and greetings, and received many small gifts by the way, all of which were transferred to the palace by him.

He also went to the mountains and beat a dozen fifth-order demon beasts for the villagers to eat.

After doing this, Lao Dao's face was as black as coal, and seeing that Wang Jinbao was going to say goodbye to the villagers who came over, he couldn't bear it anymore, grabbed Wang Jinbao's back collar and flew away......

"Wow, monkey, look at it, that beggar is so powerful, he can fly! You see he is carrying Brother Jinbao, like carrying a little chicken, it's too powerful!"

Crowd Around: ......

Road:......

Wang Jinbao: ......

Da Niu turned his head to look around, he didn't know why he praised people, and everyone was black-faced......

......

"Ziyang, are you being too cautious with such caution? Let them go now. A dull voice came,

The purple-robed man stood in the middle of the hall, and at this time there was a humanoid phantom in front of him, a bald man.

He was extremely burly, nearly three meters tall, and his muscles bulged like an explosion, like a dragon coiling, and the void was faintly squeezed and twisted.

"No, you haven't seen it, I don't know how many years I've felt like I'm on the verge of life and death, and that light cluster didn't even do anything,

Even forcible snooping has such consequences, and if it provokes that kind of being, I'm afraid it will be a big disaster, and even, I suspect that the light group has something to do with that one. ”

The face of the person known as Ziyang was solemn, and when he mentioned that person, there was a rare flash of fear in his eyes.

The bald man frowned, if it really had something to do with that person, he really needed to think about it in the long run, even if it wasn't certain now.

"Then wait a little longer, observe the place for a while, and if there is no movement, let them go down. After a while, the bald man said,

The purple-robed man nodded slowly: "Even if they confirm that there is no movement, warn them to stay away from that place, and now let's observe for a while." ”

The bald man answered, and the phantom dissipated.
