Yu Guang knew that the "Angang" they were talking about should be a giant and rare animal in prehistory, the mammoth.

Like in his dream, mammoths joined the battle, so that future battlefields would not allow these giant animals to invade the vicinity of the city.

So he took out the parchment scroll with the area north of the city again, and carefully studied it, but this time it did not take long.

After the Heavenly Fire Clan Leader and the Nine Clan Leaders had just sighed three times, Yu Guang had already painted a new parchment scroll again, which was the area north of the city to the six hills.

Yu Guang picked up this new map and explained to everyone: "Since Ang Ang is difficult to hunt, then don't let these giant beasts enter the city, all the leaders, please look at this picture......"

It turned out that he used the three canyons composed of six hills as the first natural defensive barrier, and built the canyons into fortresses and passes, and the enemy hunted them with bows and arrows at will, whether they were far away or near.

Trebuchets can be placed on the top of the six hills, and sufficient stones can be prepared, as long as a large number of enemies and behemoths are found, they can be hurled first, so that the enemies can be consumed in advance.

For this reason, Yu Guang also made a simple trebuchet out of wooden strips for the leaders of the Tianhuo clan to refer to, and the Tianhuo Witch's eyes stared directly at the trebuchet model that was placed on the ground more than a foot high, with tears in his eyes.

"If I had these artifacts earlier, my Tianhuo clan wouldn't have killed and injured so many people every Spring and Autumn Period!"

From Yu Guang to the prehistoric to the present, his thoughts are changing every moment, he once thought that in the prehistoric era, human beings were only in the period of drinking blood, but in his opinion, prehistoric people were only suffering from the backwardness of production tools, which led to the cognition of nature.

Just like the Heavenly General in front of him, the Heavenly Fire Witch, the leaders of the nine clans, and even Dashi, their intelligence is not lower than that of the people of later generations, and they immediately understand the advantage of fighting at home after their own pointing.

Rapid recognition of new things, but this is only a degree, if he has a shotgun to kill a mammoth in one shot, I am afraid that they really think of themselves as gods or demons.

When Yu Guang proposed the defense of the city wall, the leader of the fire wolf proposed to build some arrow towers on the three main roads leading to the canyon, which could delay the enemy's attack.

And the fire leopard actually proposed to plant some open land with some shrubs and thorns, leaving some hidden paths, only the people of the Tianhuo clan knew, so that they could also divert a large number of enemies, and everyone applauded after hearing this.

All the construction plans, in the big house of the Heavenly General, a cadre and others have been discussing for most of the day, Yu Guang explained to them with simple diagrams, but the basis of all this is that the production tools must be cast in advance, and there are a lot of meteorites around, Yu Guang asked the Tianhuo Witch to secretly collect them, and found a hidden place to build a workshop, which he used to burn charcoal to make tools, and then left it to the Tianhuo tribe to create some gold and stone weapons.

I was a little disappointed that there was no malachite nearby, and if there were, I could temporarily refine some bronze tools.

......

In his spare time, Yu Guang changed into the clothes of the Tianhuo tribe and walked around the camp, and he wanted to fully understand the life of this fighting tribe.

didn't let Dashi follow, this guy was too long-winded, asked that, who knew that this guy actually mistook himself for a miracle, either kneeling or worshipping, so he found a gap and secretly put on makeup.

Leaving the main camp of the Tianhuo tribe to the north, there are also three or four small camps, which are said to have started the war here whenever autumn is getting cooler. Yu Guangxiang learned more about the specific combat methods of the Ula people from here.

He was greeted by a leader named Bi Niu, and when he saw this guy up close again, Yu Guang thought of a line from a movie in later generations, "My master is eight feet tall and eight feet wide..."

Indeed, Bi Niu has bronzed skin, a rough face, a beard like a steel needle, and a huge head with a large mass of "instant noodles", and the primitive man has no shampoo, so his long hair is a little curly, all rusted together, and looks like a ball of "instant noodles".

Moreover, Bi Niu is very burly, and the body of the entire Tianhuo tribe is generally strong and strong, of course, these are in addition to some people who have been injured and disabled in battles with the Ula people all year round.

Yu Guang even thinks that this guy is very similar to a Tibetan yak, "Captain Biniu, let's meet again!" He greeted Bi Niu from a distance.

Before Bi Niu approached, he heard a sound of laughter like in Peking Opera: "The light warrior is the great benefactor of my Tianhuo tribe, look at those women, they all want to give you cubs!" ”

After saying that, Bi Niu laughed again.

Inadvertently, Yu Guang glanced at several women around him, and his crotch was cold. There were five or six muscular women around him, their eyes staring at him.

"It's better than the cow leader...."Yu Guang hurriedly refused.

Coming to Bi Niu's side, in fact, Yu Guang's height was nearly one meter eight at this time, and he was also quite strong. But standing next to the cow is a head shorter, and the body is slightly thin. Yu Guang once again lamented that in the later class, it was said that primitive people could not eat well, and their faces were yellow and thin.

Bi Niu's voice was loud, shaking his ears numb, Yu Guang waved his hand awkwardly, "The clan led by Bi Niu should be very brave among the Tianhuo tribe!" Every war here is the starting point! ”

“......”

Bi Niu wanted to say something, but he didn't say it, and hesitated for a while before he spoke: "The light warrior laughed, every time I fight, the clansmen of my Fire Bull Leader die a lot, and they are injured, and the dead let them return to the earth, but there are also a lot of missing arms and legs, and my old cow is distressed..."

Saying that, this tall guy actually shed tears, but in an instant, he squeezed out the tears in his eyes, and said to the light again with a smile: "Fortunately, the women of the fire bull collar are angry, and the little cubs have something to go out hunting every spring and autumn!" ”

After he mentioned this, Yu Guang also discovered that the Tianhuo tribe had begun to have the concept of home, and the men here were all fierce dragons and tigers, and it was said that Tianjiang had ten sons.

Tianhuo Wu is forty or fifty years old, and he is almost old in this era, but yesterday Yu Guang actually saw this old guy holding a little doll with a full moon, and heard Dashi say that it was the eighteenth son of Tianhuo Wu, and he was startled at that time.

When he came to Bi Niu's house, Yu Guang found the answer, and there was a bundle of dried eucommia hanging on a wooden pillar in the earthen house, which reminded Yu Guang of the ability of the men in the Duoyu tribe in this regard.

Eating eucommia often can improve that ability, and Yu Guang has a bit of a worship for prehistoric men. It seems that the emperors of the ancients really had this ability, and it was not a joke to give birth to dozens or even hundreds of children.

Yu Guang secretly made up his mind that he must promote this thing of Eucommia to the Tianlei tribe.
