With the explanation of the Spotted Tiger's Eminem Bitter Mask, the hatred blinded by hatred began to spread from the Tiger Driving Tribe, but from here to the Flying Monkey Tribe camp was formed for nearly a day.

And the Tiger Driving Department belongs to small and medium-sized tribes, with a population of only more than 300 people, although they have a lot of tamed beasts that can help, but the distance between them and the Flying Monkey Tribe is nearly a day's journey, and after arriving there are people and horses, how can they fight?

Yu Guang can only be an outsider now, he can't dissuade the spotted tiger from taking revenge this time, he feels that the spotted tiger is too dependent on the trump card in his hand, that is, those tamed beasts.

Walking in the tiger tribe is like entering a zoo, deer, roe deer, hare, raccoon, raccoon dog, badger, antelope, eagle, and the large one is an elephant and a black panther, but the tiger is not there, the spotted tiger glanced at the furball and sighed and said, "The last time the tiger attacked this little doll, it was injured by the beast of the white wolf tribe. ”

"That white-haired boar! In the winter I saw it get rid of two giant bears. Yu Guang said with a smile.

Maoqiu also muttered in his mouth, "In our White Wolf Tribe, those howlers don't dare to provoke the clan beasts easily, it only listens to my big words." ”

Yu Guang remembered the three of them again, so he asked, "Tabby clan leader, I don't know if you attacked the hairball last time, did the other three see it?" ”

"Hey! I'm angry when I mention this, and I didn't catch any of them! ”

It turned out that his black panther and the painted skin tiger went to attack together, but a group of two-horned moos came out of nowhere, which made the scene chaotic, and together with the four of them who suddenly appeared, none of them were caught and were injured by the flower skin tiger.

Looking at the spotted tiger with a confident face, Yu Guang felt that it was difficult to persuade him now, so he changed the topic, "Is there a problem with the eyes of the tabby clan?" ”

"Sickness? What is the disease? "Spotted Tiger doesn't quite understand.

"You can't see things clearly, you can only see clearly when you are close." Yu Guang said simply.

"Yes, yes! All I could see was vague, this mountain, this ridge, and the people of my Tiger Tribe, the big house, appeared in my eyes like a miasma, and the beast witch said that hatred was needed to lift the demon barrier in my eyes! The spotted tiger muttered a lot.

Through a short period of contact, Yu Guang thought that the character of the bitter woman was very similar to some people in later generations, and he attributed some of the responsibility to himself, and he was not very willing to show it in front of others.

"Great Leader of the Spotted Tiger, if I can let you see things clearly, you can make a pact with me, okay?" Yu Guang said seriously.

Spotted Tiger was a little surprised when he heard Yu Guang say this. It's always been a problem that bothers him about not being able to see things clearly, and today suddenly someone said that it could be solved, and he was a little unconvinced, "Okay, if you can do it, I'll listen to you, what if you can't do it?" ”

"If I can't do it, every Spring and Autumn Period, my Tianlei Tribe will provide you with two hundred backs of salt from the Tiger Tribe!" Yu Guang said firmly.

"What? Two hundred backs of salt? Seriously? Spotted Tiger couldn't believe this unashamed young man, and asked three times in a row.

Yu Guang still insisted on saying seriously, "Seriously! Two hundred backs, big salt of white flowers! I can call the shots and have someone deliver it personally. ”

The depth charge thrown at the light almost shocked the spotted tiger a little incredible, and he simply wished that he could not cure this eye disease, and got this two hundred backs of salt every spring and autumn!

"However, I need to do a check-up on you beforehand, and you have to cooperate with me." Yu Guang said again.

There are also a lot of Tiger Exorcist people around the conversation between the two, they deeply know that the preciousness of the big salt, the value of the big salt of the white flower flower in their place, sometimes they would rather continue to drink blood than to exchange with those dealers, three small clay pots of big salt can be exchanged for a half-old child.

For the sake of the development of the tribal group, they would only exchange large salt with the seller clan when there were many children living in a certain spring and autumn season, but they didn't expect that the young man in front of them could actually make large salt, which was also what shocked them even more.

For some things of the dealer's family, Yu Guang has actually been paying attention to it, and before leaving, he also deliberately explained that after the fat cloth enters the autumn, he must raise the defense of the salt village to the highest, even if the turtle shrinks into the village, there must be a certain strength to resist the external forces, you may cut off the financial route of others, and others will definitely come to investigate you, this kind of natural contradiction of human beings Yu Guang thinks that part of the prehistory and later generations.

Yu Guang asked the tribesmen of the Tiger Driving Tribe to get a large piece of dried deerskin, found a pine tobacco powder and water that he brought with him, and drew a small number of "E" characters on it, and their mouths were facing different directions, and the first prehistoric eye chart was born.

Let the tabby take a closer look, basically you can see that once he exceeds four meters after the test, his vision begins to blur, Yu Guang judged that he should be amblyopia, because now there is no silica for firing glass, that is, something like quartz is fired.

He learned chemistry very well in high school, and if he can encounter these minerals and gradually produce glass, I believe that telescopes, magnifying glasses, dressing mirrors, etc. can make people's lives more convenient in the future.

And now only the principle of small hole imaging can be used to temporarily restore some eyesight of the tabby, Yu Guang saw that there were also some colored pottery in the tiger tribe, and painted a later glasses on the animal skin.

Then let the craftsmen who can fire the pottery of the tiger tribe knead the fetal embryo according to the distance of the tabby's forehead, and finally go to fire.

I fired several in a row, because the craftsman who fired the pottery said that the position of the two temples may not be able to be fired, and the one made is a little bigger, but Yu Guang thinks that it is no problem, and some exquisite ceramics in later generations also have such things.

Everyone waited patiently until the second day, took out the burned pottery eyes, only three of the ten were fired, and the others were basically broken glasses, Yu Guang used the tip of the bronze dagger to drill a small hole in the strange ceramic eye buckled on the eye, and then coated the inside with pine smoke ink to make the inside of the black hole, only that small hole can see the outside.

The spotted tiger picked up this strange thing and put it on his nose, and Yu Guang helped him put it on, "I can't even see it!" Spotted Tiger said suspiciously.

Everyone began to talk about it, as if two hundred big salts with white flowers were about to come to their tribe, and then Yu Guang slowly let go of his hands, allowing two small holes to leak out. "See how?"

The spotted tiger felt that the thing on his eyes was a bit strange, but when Yu Guang put his hands down, he saw two bright lights shining on his eyes, and looking out through the small holes, it was clear.

"This mountain, this tree, this camp, and this big swarthy cat, I can see it clearly!" The spotted tiger knelt on the ground, and said excitedly with his hands on the soil and rocks on the ground.
