The hunting team had a lot of catches, two large wild boars plus five piglets, an adult female deer, an adult female leopard, a few rabbits and a few golden pheasants.

The two big boars and the leopard were killed, and except for the rabbits, the remaining animals that were still alive were kept in the animal pen, and those who could be fed were fed, and those who could not be fed were eaten.

"Wisdom!" Su Yan shouted to Zhi in the distance, and beckoned to Zhi after seeing him turn his head.

Receiving Su Yan's call, Zhi, who was holding a stone spear in one hand and a rattan shield in the other, walked towards Su Yan's side, and he was bored, and he also walked behind Zhi.

Outside the house where Su Yan lived, there was a large wooden table with a square table, a chair was placed on each side of the table, and the two copper shields and two wooden shields that Su Yan brought back were placed on the wooden table.

"Wang" Zhi and Biao came to Su Yan.

is also used to Su Yan, Zhi can still stand honestly, Biao can't be quiet, his arms are swaying back and forth, and from time to time he will touch his back behind him, as if his back is itchy.

"Zhi, look at this shield, the rattan shield used by the clansmen is easy to break, I plan to replace the clansmen with new shields." Su Yan pointed to the shield on the wooden table and said to Zhi.

When Zhi came here, he saw the shield on the wooden table, and he could tell that these four things were shields, but this shield was a little strange, and they all had a few spikes stuck in their fronts.

The copper shield has copper spikes stuck in it, and the wooden shield also has copper spikes stuck in it.

Just thinking about it for a while, Zhi almost understood the function of these spikes, and several scenes appeared in Zhi's mind: the first one, Zhi held a shield with thorns, and a beast pounced on him, he resisted with the shield, and the beast was injured by the spikes on the shield; In the second picture, Chi fights the enemy with a barbed shield, and he pushes the shield directly towards the enemy, but it is difficult for the enemy to attack him behind the shield......

Looking at the rattan shield in his left hand, the thought that "this barbed shield seems to be better than the rattan shield" flashed through his mind.

Zhi put the rattan shield and stone spear in his hand on the chair, and then picked up the round copper shield, the weight of fifteen catties would not have much burden on Zhi.

Zhi held the round copper shield in his left hand and moved it back and forth a few times, imitating the situation during the battle, so as to feel whether the round copper shield was easy to use.

Biao picked up the rectangular copper shield, this rectangular copper shield was heavier, but Biao didn't care, Biao's strength was second only to Dali in the dragon tribe.

The heavy rectangular copper shield in Biao's hand is like a rattan shield, and Biao can flexibly make various movements in his hand.

"King, this bronze shield is very good, I want it." Biao quickly liked this copper shield with some weight, and asked Su Yan for the copper shield with a big grin.

"If you like it, I'll give it to you, but you have to polish it well, this copper shield has just been cast, and the corners and corners are easy to scratch." Su Yan didn't care about Biao's big grin, Su Yan was very familiar with Biao's character, or the character of primitive people, who were straightforward, almost never beat around the bush, liked it, and would not go against his heart to say that he didn't like it.

"I see." Biao happily held the copper shield in both hands, carefully looking at the copper shield that already belonged to him.

At this time, Zhi had already tested this round copper shield, and it was still evaluated from the perspective of an ordinary adult male clansman, the fifteen-pound round copper shield looked a little heavy, but with the strength of an adult primitive, he was able to use this round copper shield flexibly.

However, Zhi glanced at the rectangular copper shield in Biao's hand, the copper shield was heavier, Zhi himself could use it, but it was not good for ordinary clansmen, they couldn't use such a heavy shield for a long time.

The rectangular copper shield was in Biao's hand, Zhi didn't take it, Zhi first put the round copper shield in his hand on the table, and then picked up the round wooden shield on the table.

"Light." This was the first feeling of Zhi picking up the round wooden shield.

"Do you feel that this wooden shield is very light?" Su Yan asked Xiang Zhi.

"Yes, this wooden shield is too light, lighter than the rattan shield." Zhi replied.

Even with the addition of copper spikes, the weight of the wooden shield is still not comparable to the rattan shield, the wood density of the wooden shield is about the same as the rattan density of the rattan shield, but the thickness of the wooden shield is only one point, and the rattan shield is at least two layers of rattan, and the thickness of the rattan shield is several times that of the wooden shield.

Of course, this wooden shield is not the final wooden shield, and the thickness of the final wooden shield is at least three points thick, and the wooden shield after one point does not have much defensive power, and it can be easily torn apart by the claws of wild beasts.

The wooden shield in Zhi's hand is just a mold used to make a casting mold and directly turns into a shield, which is completely inferior to the other.

Su Yan said to Zhi: "Increase the thickness of this wooden shield by three or four times, how do you feel?" ”

"Light, still a little light, this wooden shield is also easy to break, far inferior to the copper shield." Wisdom to make the final evaluation.

Su Yan didn't make a decision lightly, and found two more ordinary people among the adult male clansmen and asked them to try to use this round copper shield.

The results were similar for both of them, they both thought that the round copper shield was very useful, the weight of the copper shield had little effect on them, whether it was in battle or walking, and if necessary, they could use it to smash it at beasts or enemies.

didn't expect such a result in the end, Su Yan thought about it for a while, and felt that this result seemed to be normal.

Pure metal shields were rarely used in the ancient Chinese army, even if iron was less dense than copper, the output of metal was a reason, the most important thing was the weight of the shield, the weight of the pure metal shield was unbearable for the soldiers, so it was natural to choose a light weight shield, even if it would reduce the defensive power of the shield.

It is different in the primitive era, the power of primitive people is greater, and they can withstand heavier shields, Su Yan determined this round shield, and will cast round copper shields in batches in the future to replace the rattan shield, but the size of the copper shield should be replaced, and a more suitable size should be selected.

Fortunately, the dragon tribe has a lot of blister copper production, it can produce sixty-five catties of blister copper a day, and a fifteen-pound copper shield can be cast on four sides a day.

Putting down the matter of the copper shield, Su Yan thought of a problem that may only appear after a long time, the round copper shield in front of him is suitable for the use of the dragon tribe, but in the future, the dragon tribe may encounter the primitive tribe that has begun to use bows and arrows, once there is a conflict with such a tribe, the round copper shield cannot completely cover the body of the clansmen, and it is necessary to replace the larger shield.

The large shield cannot be cast from coarse copper, it is too heavy, wood is a better choice, and you can also wrap a layer of animal skin on the outer layer of the wooden shield, such a shield is completely sufficient for defense.

Wrapped in a wooden shield of animal skin, Su Yan wrote down these words on the animal skin.
