"Look at this." Dai Huadong threw a small metal can to Princess Hai.

The sea princess easily caught the metal can, looked at it carefully for a while, and said, "What is this?" ”

"Canned food, a thing that preserves food for a long time, after being treated with anti-rust treatment. It can be stored for more than a year. Dai Huadong said, "How? This kind of stuff should be pretty useful to you, right? ”

“……”

"The second is these searchlights, which allow you to explore deeper into the ocean. It has a pretty large lighting range, so it's quite what you need, right? With this, you can expand your influence into a larger sea. Dai Huadong took out an underwater searchlight.

“……”

"The third type, that is, the marine soul guide, but this thing is still being researched, so it can't be used for trade yet. That's the main thing we can do with you. ”

The sea princess was silent for a long time and said, "What do you want?" ”

"Minerals on the seabed, precious stones, and the safety of navigation on the surface." Dai Huadong said, "These things are what we need at the moment, and as for other things, we haven't thought of them yet." It can be supplemented in the future. ”

"......" The sea princess was silent, indeed, these things are what they need, especially that kind of searchlight, if it can really stay bright at the bottom of the sea, then it is not impossible to build another city of the mermaid clan, after all, the minerals that can emit light are not available everywhere. In this case, it is not impossible to agree.

"How many of these lights can you provide, though?" Princess Hai took the searchlight that Dai Huadong turned on and put it into the water, observed the effect, looked at Dai Huadong and said.

"It's a time of war, so we can only sell you a small number of searchlights, and if we win after the war is over, I'll sell you as much as you want." Dai Huadong said.

"War?" The sea princess frowned.

"But you can't trade with us for too many minerals we need for a while, can you?" Dai Huadong said, "Then don't be too little, this thing is very troublesome to do waterproof treatment." ”

"Yes, but the Emperor of the Humans, are you just talking to me about this deal?" The sea princess said.

Dai Huadong nodded and said, "Yes, that's all." ”

"As for the way the food is preserved, we ask for the technology to be exchanged, and I can trade the mermaid's tears in exchange." The sea princess said that the food could not be completely left to human hands.

Dai Huadong shook his head and said, "I said a long time ago, this is something that only humans living on land can do. I can tell you directly that the food needs to be cooked and sealed to preserve it, and you can't do that with fire in the middle of the sea. And the cans for preservation are not made directly from iron ore that will be rusted in the sea, but must be refined, and this requires a fairly high temperature, and I don't think you can make steel in the sea. ”

......The sea princess was silent, indeed, they really couldn't do this, living in the sea doomed them to not be able to develop a fire-based civilization. Their civilization is still in a rather backward state, and although there is a city, it still grazes fish and grows seaweed as its main food source, and it cannot be preserved for long.

"Very good, then ......" Dai Huadong took out a piece of paper, handed it to Princess Hai, and said, "Your Excellency Princess Hai, please carefully check what you think is unreasonable on it, and if it is confirmed, then sign your name below." ”

Princess Hai looked at the specific clause on it, and at a glance, there was no big problem. So she nodded and signed her name.

"Well, then this is a commercial token, let's make some small-scale transactions first, and then start a larger-scale cooperation after both parties have understood." Dai Huadong said with a smile.

"So now you can tell me about the Snow Emperor, right?" The sea princess said.

"Then you can ask her yourself, and I won't bother you." Dai Huadong said, and then drilled Shermanry.

"So ......"

……

In the Mingdou Mountains, the defenders here are ready to retreat, and the supply line has been completely cut off, and it will be impossible to support it if it continues like this. The Star Luo Empire was changing shifts around the clock, so they finally couldn't withstand the pressure and went back to eliminate the rebels who occupied the supply lines. At present, they can no longer take care of defending the Star Luo Empire, and the territory is gone, and they can take it back, if these two soul master groups are broken here, it is unlikely that they will have a chance to rebuild.

As a result, the Ming Dou Mountain Range was declared lost, and the Xingluo army advanced into the territory of the Sun and Moon Empire.

After learning this news, the Star Luo Emperor was completely at ease, and he couldn't ask for the battlefield to be placed in the Sun and Moon Empire, so as to avoid the destruction of the Star Luo Empire itself as much as possible.

Speaking of which, at present, among the three major empires of the original Douluo Continent, the Douling Empire has suffered the smallest loss, only the losses of those soldiers who support it, and the others are almost unharmed. The Northwest Army of the Star Luo Empire was almost defeated, but fortunately, it was quickly reorganized, and once it counterattacked the Sun and Moon Empire, the benefits gained could completely cover the losses. And the Heavenly Soul Empire was the worst, the army was almost completely defeated, and only occupied the remaining few cities to barely survive.

The Emperor of the Sun and Moon Empire, Xu Tianran, was furious when he heard the news of the loss of the Ming Dou Mountain Range, and then locked himself in the palace without seeing anyone.

On the Metrology Officer's side, after learning that the Mingdou Mountain Range was lost, her expression didn't change much, and she just passed the news back through Wo-chan, who assisted her in the battle.

However, this is not particularly important to Dai Huadong, the army of the Star Luo Empire is attacking the Sun and Moon Empire, which is not a big problem. In contrast, it was the main army of the Sun and Moon Empire on the orange side that made him care more.

This war within the Sun and Moon Empire will determine the direction of the continent in the future, once the expeditionary force defeats the Morning Star Gongzao, then the Sun and Moon Empire will be able to ease its breath and defeat those rebellious nobles, while blocking the counterattack of the Star Luo Empire. And once the Morning Star Crafts wiped out the Expeditionary Force, the Sun and Moon Empire would be completely finished.

This war, which decided the fate of the Sun and Moon Empire and the future direction of the Douluo Continent, finally broke out when the expeditionary force arrived in Maple Leaf City.
