Chapter 691

"Just when people were worried about the damage of the barrel, they found a relatively soft metal lead." the man continued, "lead is very soft and won't hurt the barrel. Moreover, it's easy to process. You can carry molds with you and process some bullets in your spare time."

"So this lead bullet is so good!"

"After that, when guns evolve to advanced forms, don't you always use this lead bullet, brother, you sent it!"

The popular science man continued to say in the group: "no, the lead bullet also has certain defects. The bare lead pill is too soft, which will lead to the phenomenon of hanging lead and affect the shooting of the next bullet. Therefore, it is considered to cover a layer of metal on the lead bullet."

"You mean copper?" someone interrupted.

"Yes, at the beginning, many kinds of metals were tested, but copper is relatively the best! This is the copper by armour bullet, which is the kind of copper bullet we often see later," the man replied.

Hearing this, Xiao Yi moved in his heart: "isn't this the bullet I just signed in to get? I didn't expect it to be more advanced than lead bullet. Good! However, this man is really knowledgeable!"

"Didn't I also send it? A copper vein has just been refreshed in our alliance!"

"Yes, you will send it in the future, but now everyone doesn't have the technology to make copper quilt armour shells. Now you can't send it!"

"It's all right. We always have to look forward and develop in the future!"

Seeing this, Xiao Yi shook his head, switched to the private chat channel and sent a message to Xiong Di: "Xiong Di, has there been any change in the aborigines on Xinda road?"

"Go back to the island owner, no!" Xiong said. "Now they don't seem to stop us at all. They just attack us after we open the treasure chest."

"I've expected it for a long time. It's all right. Let's pay more attention to the aboriginal sneak attack." Xiao Yi told me.

"Yes!"

After Xiao Yi finished chatting, he thought about it and rushed to the medium transmission array.

"Good morning, island Master!" Shi Kong immediately greeted Xiao Yi when he saw Xiao Yi. Other dwarf engineers also said hello to Xiao Yi. After all, the wine on the island is really delicious.

For these engineers, there is no limit. Drink freely!

This makes them very happy, so the construction of this medium-sized transmission array is very serious and responsible. At the same time, they almost know everything and say everything about the questions asked by Shi Kong!

"Everyone has worked hard. It is expected that the transmission array will be completed in a few days?" Xiao Yi asked.

A dwarf engineer replied, "according to the current progress, it will take another day. Is the island owner in a hurry?"

"No, just pay attention to the progress of the project!" Xiao Yi replied with a smile.

The dwarf engineer said, "we'll finish it as soon as possible!"

"Thank you!" Xiao Yi arched his hand.

After thinking about it, Xiao Yi went to the small transmission array on one side and carried some bottles of good wine to the dwarf country.

After walking out of the transmission array, Xiao Yi was immediately stopped by one guard and asked, "who are you looking for?"

"My name is Xiao Yi. I'm an outsider. I came here today to visit Los!" Xiao Yi replied.

The guard's eyes lit up when he heard that he was called Xiao Yi. Who doesn't know Xiao Yi's name in the dwarf country now.

Now the drinks of the whole dwarf country are basically occupied by Xiao Yi's drinks.

"Are you Xiao Yi, who can make wine very well?" the guard asked excitedly.

"I can't make wine, but I have a professional wine maker!" Xiao Yi replied with a smile.

"Well, we'll inform Lord LOS. Please wait a minute!" the guard said with a smile.

Xiao Yi nodded and said, "thanks a lot. Try this new beer!"

"Then we're welcome!" the guards licked their lips.

Xiao Yi took out one of the large bottles of beer and poured it on them. The guards took it up and drank it, and then his face showed an aftertaste.

"What day is it today, my friend? Why are you here?" Ross came over and asked.

Xiao Yi replied, "come and see you. At the same time, I also want to talk about business with you!"

Los took Shay to the trading post of the dwarves.

"Do it, let me see what you brought me today?" said Ross happily.

Xiao Yi put the good wine on the table, and Los opened it excitedly.

I poured a cup and tasted it carefully. After a long time, I said, "the winemaker on your island is really great!"

"Really good!" Xiao Yi also said.

"Tell me about the business you want to talk about!" said Ross, holding his glass.

"We still need to build a medium-sized transmission array!" Xiao Yi replied.

Ross frowned slightly and said, "this time, as last time, trade with the virtual currency on your island?"

"Of course, this is what I want most. I don't know what your country means?" Xiao Yi asked.

"I'm afraid not this time!" returned Ross.

Xiao Yi looked at him in surprise.

Los continued to explain, "well, we have understood your battles with those cities and countries, and we have also determined that the sea is rising and inundating the continent."

Xiao Yi nodded and waited for his words.

"So our king has issued an order that if it is not necessary, the domestic cornerstone will not flow out for the time being. And if the outside world wants to buy our domestic goods, it must use the cornerstone!" Los said reluctantly, "this order has been written and issued, and I have to abide by it!"

Xiao Yi nodded and said, "well, I understand. It's human nature! Thank you for your help last time!"

"That's not mentioned, so this time if you really want to build another medium-sized transmission array, you really need to use the cornerstone to trade!" Ross said.

Xiao Yi thought for a moment, got up and said, "OK, I need to think about it."

"However, our king also said that if you can give up an alien Island, our dwarf country can buy an island with a large number of cornerstones!"

Los's words made Xiao Yi stop again when he was ready to step out.

"What? Do you want to buy an island?" Xiao Yi asked in surprise, but on second thought, it didn't seem difficult to understand.

Now that the dwarves have known the fact that the sea is gradually flooding the mainland, they must leave a way for themselves. At present, it seems that it is most appropriate to have a survivor island!

With the huge amount of cornerstone in their hands, they will soon be able to expand the island to an area enough for them to live!

"Yes, after all, this continent probably won't last long. We always have to make plans early!" Los replied.

"Well, we have to discuss this matter before we can reply to you!" Xiao Yi replied carefully.
