After stabilizing the situation in Italy, Cheng Yang left there. Although there are still two countries in Italy, China is still in the hands of hellos. However, Cheng Yang doesn't need to worry about this, because he has already sent TAN Chao to the Vatican state to carry out the assassination plan.

TAN Chao has long been itching for the assassination, but because he wants to find out the trend of the orcs in Australia, he has never dared to make a rash move.

However, during this period of time, TAN Chao led his dark soul camp to find out the real and the virtual of the orcs in Australia.

The orcs in Australia are indeed powerful, and there are as many as a thousand orcs above the fifth level. As for the king of beasts here, although his rank is only in the middle of the fifth level, he is a real strong yellow level. In other words, his actual combat effectiveness has reached the early stage of the sixth stage.

It is conceivable that the Australian orcs, led by such a strong man, have a strong fighting capacity.

This is not the focus of TAN Chao's investigation. His biggest task is to find out when the orcs from Australia set out to attack Southeast Asia.

Although there are only some speculations about whether the Australian orcs will attack the Southeast Asia region, this speculation is very likely, because the Southeast Asia region is the closest direction for Australian orcs to expand.

The fact also proves this point. TAN Chao led the dark soul camp to stay in Australia for half a month, and finally got the relevant information. The orcs of Australia will set out from Sanger city in the northern coastal city of Australia on the second of next month, and the whole sea area will be less than hundreds of kilometers away.

At present, although New Guinea is not completely in the hands of the orcs, there are also two orc forces operating on it, and they are fighting with the local people.

Obviously, if the orcs from Australia enter New Guinea, there will be almost no suspense about human defeat.

Now it is May 27 in the last calendar, and it is only five days away from the second day of the next month, which is the main reason why Cheng Yang immediately fell back to Fengcheng.

Of course, there's another reason for that, and that's about the psionic submarine program.

Half a month ago, the research and development of submarines by the psionic Research Institute had come to an end, and the most critical technology, the psionic cannon, was broken through by the lava cannon Cheng Yang had brought back. Now the submarine in Luofeng city is not only a vessel that can navigate under water, but also has a very strong combat capability.

However, research does not mean that it can be made immediately. Luofeng city has spent more than ten days to build only three such submarines.

In order to commemorate the launch of the submarine designed and manufactured by Luofeng City, Cheng Yang gave it a resounding name, Jiaolong.

The first batch of Jiaolong was naturally Jiaolong 1. As for whether there will be jiaolong-2 in the future, it is still unknown. It depends on the use of jiaolong-1.

Jiaolong is not defined as a submarine, because it has been out of the scope of the boat, that is a super warship. Therefore, in the division of warships in Luofeng City, it is called deep-sea warship.

Each Jiaolong is more than 400 meters long and has 16 large psychic cannons in all directions.

This kind of huge psychic cannon is also the most resource consuming place of the whole warship. Whether it is the materials needed to sketch the magic array or the metal used to pour the gun barrel, it is very expensive.

It is estimated that Luofeng city in the world has the ability to gather enough resources to forge such huge guns. Other forces, even if there are almost, can only hope and sigh. This kind of cannon is definitely a high-end luxury.

The psionic cannon is not only expensive to build, but also very expensive to use. It costs at least ten level 4 psionic stones if it is fired in one shot. If it is used with full power, it needs hundreds of level 4 psionic stones.

After all, according to the previous design, a psionic cannon can only use one psionic stone at a time. To produce more power, you must use a higher level psionic stone, such as level 5 psionic stone.

However, after the improvement, the psionic cannon can use multiple psionic stones to charge at the same time, which undoubtedly solves the biggest problem. Now Luofeng city does not lack level 4 psionic stones, only level 5 psionic stones.

Of course, the power of the psionic cannon can also meet its huge consumption. Even if only a dozen or so level 4 psionic stones are used, it can instantly kill the mid fifth level existence. This so-called bombardment kill is not a one-to-one bombardment, but within the range of power, all targets below the middle of the fifth level will be killed in seconds.

If you use hundreds of fourth level psionic stones, the power will be astounding. Cheng Yang is not clear about the specific level, because there is not enough powerful existence to test the power of this kind of shell.

After Cheng Yang returned to Luofeng City, he summoned Li Wanshan and others to Luofeng city at the first time.

Wu Jianzhou was the first to arrive. As soon as he came in, he asked with a smile, "Lord, what's the big move this time?"

Cheng Yang said: "do I ask you to come over there must be big action?"

Wu Jianzhou smiles but does not speak, that facial expression very obviously approved Cheng Yang said.Cheng Yang opened his mouth and said, "well, there are new actions. TAN Chao has already inquired about the relevant information. I am going to start the operation soon and let the Jiaolong go to the sea to test its power. "

As soon as Cheng Yang's words were finished, a man outside rushed in. It was Tao Yu. He was very worried and said, "Lord, it seems that we don't need to wait for the Jiaolong to go to Australia to test its power. There will be a big war to fight next."

Cheng Yang and Wu Jianzhou were all stunned and asked, "what's going on here?"

Tao Yu said: "well, just now we have received the news that the sea people in the southeast of our country are gathering. At the latest this morning, they will launch an attack. Their goal is very clear, that is Xiangyang City. And judging from the scale, this time, the other party will never be a small fuss

Cheng Yang was suddenly depressed and said, "these guys are also jumping out to make trouble now. When we fall into Fengcheng, it's easy to make trouble with them?"

Tao Yu said with a wry smile: "maybe it's because they think it's not easy to make trouble with us in Luofeng City, so they launch this attack with all their strength. If I'm not wrong, those sea people should have got the news about the Jiaolong deep-sea warship, so they can't sit still now. "

Cheng Yang suddenly asked curiously, "Tao Yu, how did you get the news when those sea people gathered in the sea?"

Tao Yu said: "the Institute of psychics has studied the Jiaolong, which is a major project. In the process of studying the Jiaolong, the Institute has also produced a number of ancillary products, one of which is the submarine cruiser. This kind of submarine cruiser can move quickly in the deep sea, and it can camouflage on the bottom of the sea. As long as it is stationary, no one can tell that it is a ship. Of course, the cruiser also has weaknesses. First, it can't attack. Second, the head is very small and can only accommodate one person. But it can't be more suitable for investigation. "

"It's a good thing indeed." Cheng Yang is very interested, but this is not the time for detailed questions. He immediately said, "since those sea people are going to jump out at this time, let's give each other a surprise first."

Tao Yu and Wu Jianzhou looked at each other, and then Tao Yu said, "Lord, I'm afraid these sea people are not so easy to deal with. At present, we only have three deep-sea warships. I'm afraid we still can't catch up with the almost endless sea people. Let alone other things, the only consumed power stone is an astronomical number."

Cheng Yang frowned. He really didn't think about this problem. Although the three Jiaolong deep-sea warships were powerful, their consumption was not enough for ordinary forces to bear. Especially in the super large-scale war, if all depended on the powerful cannons, Luofeng city would be bankrupt.

"What do you think?" Cheng Yang asked.

Tao Yu thought for a moment and said, "Lord, in my opinion, we can let those sea people attack Xiangyang City. After the other party has been fighting for a period of time, we can use powerful cannons to fire a few guns in the rear of Xiangyang City, which will definitely make the other party's army in turmoil. Then we will take advantage of the victory to pursue. We believe that the sea people will certainly be unable to resist it."

Cheng Yang said: "this is a good tactic, but now part of our army of instrumentalists is stationed in the fortress of huangquan, and some are still in the state of Italy. There are not many people who can be used to prevent hellos from escaping from China in those two countries."

Tao Yu said, "Lord, you are too modest. If you are here, you will be able to top a million troops. Besides, don't we have territorial guards? Hire another group of fourth level mercenaries. With your aura of blood domain, you will be able to kill those sea people crying for their father and mother. "

Tao Yu's analysis is slightly optimistic, but it is also reasonable. If we can hire a batch of awesome mercenaries, with the help of Cheng's blood aura, we can really produce strong fighting power, let alone the assistance of arrows and magic towers.

"Are mercenaries too wasteful? In such a war, without tens of thousands of mercenaries of the fourth rank, I am afraid it is impossible to play a significant role. " Cheng Yangpo has some problems.

Wu Jianzhou said: "Lord, you don't have to think about this. Even if you hire these fourth level mercenaries to fight for one or two days, the consumption is only about 10000 level 4 psionic stones, which is not a big problem for our territory. Moreover, according to my estimation, there must be a lot of level 5 among the sea beasts under the command of the sea tribe. After killing, you can get the fifth level demonized beast crystal. Although this kind of magic beast crystal can't be used to improve the strength directly, there is no problem to use it as a level 5 psionic stone. We won't suffer at all. "
