The submarine plan proposed by Milia was very interesting, so after testing the missile, Kinan began to study the possibility of the submarine's success. Sure enough, as I thought, as long as the tightness is strengthened.

As for the barrier emitted by the Light Stripe Tree, there is still no way, although this barrier is better waterproof. However, once the weapon is used, it will still allow the sea water to enter through the open barrier gap, and there is no way for Chi Nan to do this.

"The problem of oxygen is not a problem, I remember that there used to be a plant that can separate oxygen bubbles from the sea, and it was only used as an oxygen pump to raise fish, and this thing can be used, as long as the oxygen content is controlled. It also absorbs carbon dioxide, which is good, so that's it. ”

Having solved the air problem, the next thing is the problem of weapons in the sea. The best weapons in the sea have always been water attributes, and there is only this problem that Chi Nan has no way to solve.

In the past, submarines were just exploding with explosive mushrooms, and their power was not much at all.

If it weren't for the fact that no alternative weapons had been found, submarines would have been able to cross the sea long ago. But now it's time to put it on the agenda. Forget it, let's let the submarine find some special plants in the sea first.

Speaking of which, there are really not many plants in the sea. There are many types of plants, but it is not easy to use them all.

It's not enough to be alone, how much can you do before? Fortunately, now that you have an energy pool, it's easier.

The next thing to do is to increase the number of energy pools, as well as the speed at which they can regenerate their health mana. With these things out of the way, it seems that I can start experimenting with another idea of my own.

While Chi Nan was researching submarines, the Maro Kingdom finally couldn't support it. At this time, inside the palace of the Maro Kingdom, the atmosphere was solemn. All the people did not dare to breathe, and only when the king asked, they would answer.

In this solemn atmosphere, the meeting also progressed very strangely. But there is no way, at this time, if you are not careful, you may become a substitute ghost. Looking back, the scene of laughter and talking freely in the Maro Kingdom a few months ago is now gone, which is really nostalgic.

Who would have thought a few months ago that the kingdom of Maro would end up in such a field. The rise of the Holy Tree Territory was so fast that even the help of the Holy Dragon Empire could not suppress it.

This kind of means, this kind of power, I'm afraid only those top kingdoms can do it. Could it be that the Maro Kingdom has not yet reached the height of the coveted top kingdom, but has let the Holy Tree Leader reach it first.

Top kingdom, it's really a longed-for term, but when this kind of power appears on your doorstep, and this force is still attacking you, it makes everyone unhappy.

"So, I now propose to make peace with the Holy Tree Leader, what do you think? ”

As the king said this, the originally solemn atmosphere suddenly eased. No one dares to take the lead in putting forward this kind of opinion, otherwise after the peace talks are over, the person who proposed the peace talks will definitely become a substitute for the dead.

This is the kind of thing that the king himself is reluctant to propose, but in the end someone has to bring it up. The king proposed, at most, he would be burdened with infamy, but if they brought it up, it would be fatal. At this time, the king's heart was bitter, but he could not put it off any longer. If it continues, half of the Maro Kingdom will be gone.

"Your Majesty is wise, but the details of the negotiation, as well as the conditions proposed, need to be considered clearly. ”

An old man spoke in agreement. In an instant, it became like a wet market, and everyone was discussing the details of the negotiations. As for the king, not many people pay attention to it now.

This invasion of the Sacred Tree Territory can be said to have completely swept away the majesty of the king of the Maro Kingdom, and there is not much left.

While they were discussing, letters of peace talks had already been sent. With the help of the Holy Tree's own passage, the contents of the letter had been delivered to Chi Nan in less than an hour.

"I didn't expect them to be able to hold on to this time, and I thought they wouldn't be able to hold it anymore. However, why should I accept their peace talks, the entire Maro Kingdom can't run away now. ”

Chi Nan sneered, of course their own army knew that they were already completely surrounded by airships. As long as other kingdoms and empires don't help, the people of Maro Kingdom can't escape if they want to, so what are they afraid of.

Such an important matter, of course, was brought by Hemira to deliver the letter. "The Maro Kingdom has said that if we don't agree, they will ask for political asylum in the Holy Dragon Empire. ”

"Political asylum? Isn't it just running away, what does it matter, I don't want their people. ”

Chi Nan rolled his eyelids and ignored it at all. Hermila knew that Chi Nan had exposed the problem of lack of common sense.

"My lord, the so-called political asylum does not mean that the royal family wants to run away. The kingdom's asylum to the empire is equivalent to giving its own land to the empire. After that, the royal family would retain their status and name and go to live in the empire. However, the Maro Kingdom itself has become an absolute subjunct of the Holy Dragon Empire, and will be controlled by officials sent by the Holy Dragon Empire. ”

"Once they offer political asylum, then the Holy Dragon Empire can officially intervene and send troops to deal with us. ”

"The Holy Dragon Empire sending troops? "Chi Nan understands that the Holy Dragon Empire seems to be at a disadvantage all the time, but that is within the rules. Once the troops are actually dispatched, they are far from being opponents with the strength they are hiding now. The most important thing is that the heritage of the empire, as well as those legendary masters, is what Chi Nan does not want to face.

After a long time, Chi Nan finally said, "What other conditions do they have?" ”

"They said that the details of the peace talks need to be discussed, but we must stop all offensive behavior. ”

Chi Nan nodded lightly: "It's okay, just use their existence to temporarily appease the Holy Dragon Empire, we still need time to develop." At this moment, Chi Nan had already communicated with all the commanders on the front line.

It was so easy for the Holy Tree Leader to give orders, as long as Chi Nan moved, he could receive his own orders within his control. The commanders immediately began to order the army to stop the attack and begin to consolidate the territory that had been gained.

When the Maro Kingdom saw this change, it finally breathed a sigh of relief. This action represents Chi Nan's agreement to the peace talks. If it weren't for the fact that there was no way, no kingdom would want to offer political asylum.
