Liu Xin, who had completed all the preparations, started the first forging after entering the island, although there were a lot of raw materials left for Liu Xin, but they could not be wasted.

Liu Xin directly took out the large stone pot that had been polished before, this stone pot was carefully polished according to the tools in Liu Xin's memory, and it could definitely resist high temperatures.

Making a fire, heating, stirring, and one process after another, Liu Xin has always relied on vigorously holding himself to complete, after all, Liu Xin has no legs and cannot move freely. Liu Xin chose the mold refining method, because he lost his legs and couldn't move freely, let alone strike iron, so he could only use molds and make iron tools in batches, but this was also good, he could produce weapons and equipment in large quantities, and meet the needs of pigs and lizardmen as quickly as possible.

On the first day, there were 30 broadswords made, and after these 30 broadswords were polished, they could easily cut off the trees with the strong strength of the pigmen, but the knives were not damaged at all. This made the eyes of all the pigmen and lizardmen widen, that is, the pigmen's immense power could exert such an effect.

These big knives were specially customized by Liu Xin for the pig man, and the thickness of the knife was deliberately increased to prevent the pig man from breaking the big knife due to excessive strength. However, this big knife can also be used by the pig people, because the thickness of the blade is increased, so the weight is also increased, and the lizard people can't use this big knife at all, although it can be lifted, but it is too laborious to wield.

As for the lizardman's weapon, Liu Xin is designed to be a lighter scimitar, the lizardman's characteristic is that it is fast, and the characteristics of the lizardman cannot be played because of the equipment, and the green skin of the first scimitar can't wait to experiment, relying on a fast sprint, the scimitar can also cut some fewer trees, so it is enough to deal with the fishman.

It took Liu Xin three days to finally complete the production of the weapon, and the weapon only needs to pour the molten iron melted iron ore into the mold to complete the production. The next step is the production of armor, because of the lack of legs, Liu Xin, who is unable to move, can only make some changes to the armor. First of all, a lot of thick iron plates are made by relying on molds, the pig people are some thicker iron plates, and the defense is good, and the lizardmen are some smaller iron plates, so as not to affect the movement of the lizard people. Then came the most difficult part, how to connect the iron plates.

Liu Xin, who thought about it, finally decided to use the iron ring buckle, after all, there is a pig man, and there is no need to worry that he will not be able to connect the iron plates through the iron buckle. The first batch of equipment of the pigmen and the lizardmen was completed in this way, even if Liu Xin left some equipment as a backup, it would be enough to arm more than 20 pigs and more than 30 lizardmen, and the first batch of armed forces of the pigmen and lizardmen was also completed.

Pigmen and lizardmen, armed with weapons and armor, finally stepped out of their encirclements and began to look outside for food. The sharpness of the weapons, the sturdiness of the armor, and the need for food from the clansmen made this armed force even harder, bringing back a lot of food every day.

But after a period of going out to hunt, Liu Xin also found a problem, that is, the consumption of iron tools is too fast, and a new set of equipment can only be used for 5 days at most. Because the team that went out hunting needed to take care of the food of the whole clan, when attacking, they all relied on the solidity of the armor, and did not defend at all, all the defense was completed by the armor, and some attacks that could have been dodged were also resisted, which accelerated the consumption of the armor.

In the end, Liu Xin had to talk to Greenskin and inform them of this serious problem, if they continued like this, they would definitely use up all the iron ore before the fishmen attacked. This problem can only rely on vigorous and green skin to slowly do ideological work, Liu Xin also made another preparation, teaching the pig man to strike iron, the lizard man is not strong enough, can not complete the work of iron, the iron can only be handed over to the pig man to complete.

Liu Xin also thought of more questions, if this development continues, the fish people can definitely be dealt with, what about the future? If you just teach the pig man to strike iron, you will not be able to guarantee that the pig man will have a tyrant in the future, and then rely on the iron striking technology to directly destroy the lizard man, which is what Liu Xin does not want to see.

In order to balance the two races, Liu Xin taught the pigmen to strike iron, while the lizardmen taught them how to identify various minerals, after all, the speed of the lizardmen was there, and they could find all kinds of minerals faster by relying on their speed. In the future, the lizard and the pig man can reach a balance point, the lizard man is responsible for finding minerals, and then the pig man is responsible for making, although there is still some unfairness, but this is the best solution that Liu Xin can think of, Liu Xin's thought exchange technique can not help but transmit ideas, but also pass pictures, which solves the biggest difficulty of Liu Xin's teaching of the two races - unable to demonstrate.

The lull lasted for more than half a year, and the pigs were able to craft their own weapons, and the lizardmen could find all kinds of minerals on their own. The equipment of the alliance of the two clans has also been continuously upgraded, becoming more advanced ten-refining weapons or even hundred-refining weapons, which are much stronger and can be used for a longer time.

After more than half a year of searching, the fish-people finally found the location of the two clans, and the fish-man spies began to appear outside the fence continuously. The moment the alliance saw the fish-man spies, they were still a little worried that they would be attacked, but when they looked closely, they found that the fish-people really couldn't cross the high fence, so they were relieved.

Although the two clans were relieved, Liu Xin did not relax, if the fish-man was on land for a long time, there would always be some geniuses who could learn to climb trees, and then teach other fish-people to climb trees, this fence could not stop the fish-people, at most it would last for a while.

"Other ways to raise fences and build fortifications are all ways to cure the symptoms but not the root cause, and only by solving the Naga behind the fish-man can it be possible to coexist with the fish-man, otherwise it will be a life-and-death situation. Relying on the evolution speed of the pig and lizardmen, it is difficult to catch up with the fish-people ruled by the Naga, and if the Naga is not solved, the fish-people will eventually be dealt with. As for getting Naga, you can determine whether the fish-man is really oppressed, the probability is about fifty percent, and it is worth the gamble. Liu Xin had thought of this layer from the beginning when he saw the fish-man, and now he is even more determined to solve the idea of Naga.

"Vigor, Greenskin, do you think it's safe now?" After Liu Xin found Dali and Greenskin, he asked Dali and Greenskin.

"yes, now that the fish-people are also kept out, we can go back to our old lives." Dali, first of all, said what was in his heart without much thought.

"Well, I've known for a long time that I asked you for nothing, Greenskin, what do you think?" Liu Xinyou turned his head to look at Greenskin, but looking at Greenskin's appearance, he knew that his thoughts were the same as Dali's.

"Well, you really haven't thought much about it, the fish-people can come from the deep sea to the land, who can guarantee that they can't learn to climb trees? What if they learn to climb trees? What are we going to do? Liu Xin directly said the most acute question, and Dali and Greenskin were silent after hearing it.

"What we need to do now is to deal with the Naga behind the fish-man, and if we don't solve the Naga, then peace will never come. After solving the Naga, there is still half a chance of peaceful coexistence. Liu Xin didn't speak again after explaining to Dali and Greenskin, and then it was time for the two leaders of Dali and Greenskin to make a decision, if they attacked, the two clans might suffer heavy losses, and if they didn't attack, they couldn't tell what kind of disaster they would receive in the future.

The two leaders also knew about this relationship, so they did not make a decision lightly, but hoped to wait two days for them to discuss it with their clansmen. After all, this is a matter of survival for the entire race, and it is not up to one leader to decide.

In the past two days, Liu Xin has been trying his best to improve the weapons and equipment of the two clans, after all, more kinds of ores have been found by the lizardmen, and higher strength alloys can also appear.

In the afternoon of the next day, Dali and Greenskin finally came to Liu Xin, and both of them agreed to attack, for the sake of their descendants and the future of their clansmen, even if it was worth sacrificing some now. After receiving affirmative answers from the two clans, Liu Xin also put the alloy technology on the table. Begin teaching the pigmen how to craft metal weapons and armor.

The two clans began to get busy again, iron-working, prospecting, and exercising, and the entire garrison of the two clans had begun to be lively, all beings could find what they had to do, and all the clansmen were preparing for the great war in the near future.

Half a year after the appearance of the fish-man scouts, the two clans had almost completed all the equipment replacement, and all the adult pigmen and lizardmen had been given weapons and armor, and the training was almost complete, and there was enough food for the adult people. There is a strong fighting spirit in the entire station, and all the pigs and lizardmen are ready for a big battle, and the final general attack is coming.

The next day was also a sunny day, just in time for the decisive battle. Liu Xin decided to take the initiative to attack with the pig people and the lizard people, and now his side is under the influence of the fish people, it is estimated that he is the timid and afraid side, as long as the fish people do not go too far, it will not cause Liu Xin's side to counterattack. It's a pity that they don't know that behind the pigman and the lizardman, there is a human being, and this human still knows the fish-man very well.

Liu Xin didn't want to continue to launch the pre-war mobilization, he had already said enough time to prepare, and if he was verbose for a while now, it would definitely discourage everyone's enthusiasm. Besides, Vigor and Greenskin had already informed all the clansmen last night that they were going to counterattack the Fish-People today and eliminate the Naga behind them.

The armies of the two clans marched towards the swamp where the fishman was, and in order to deal with the impact of the swamp on the two clans, Liu Xin definitely used a tactic. Sacrificing a part of the old pigs and the elderly lizardmen, so that the fishmen thought that their side was no longer good and prepared to retreat, the fishmen saw that this was already all the combat strength of the two clans, and they would definitely do everything possible to pursue the alliance of the two clans and completely wipe out the power of the two clans, after all, this was a good opportunity, and Liu Xin and them had the possibility of victory after leaving the swamp.

After all, there is still a certain amount of risk in this method, if the Naga behind the fish-man is calmer, the loss of combat power on his side will be in vain. But there is only a thirty percent possibility in Liu Xin's calculations, after all, the rule of the Naga tribe is too strong, this is the idea that they have been instilled by the previous generation since childhood, as long as they have the opportunity, they will definitely occupy the entire land, so Liu Xin deliberately created the "opportunity", even if the Naga tribe finds something wrong, they will jump into it.
