These are all basic courses, but they also took these highly qualified students twenty days to complete.

Next, Luo Ming began to teach them the more advanced part: translating a passage into pinyin, and then translating it from pinyin to numbers. When dealing with people from other countries, people who have not received such training can no longer understand this. But these numbers can only be called clear codes for the people of their wolf's den.

All trained trainees can easily understand this kind of writing, and if there is a traitor among their own people, this kind of clear code will expose the secret information.

So what is a password? It means that the two parties to the information exchange agree on a simple mathematical formula, and then all the translated plaincode numbers are changed through this formula. For example, all numbers are multiplied or divided by the same fraction.

After such a transformation, the plain digit becomes a password. In the case that ancient mathematics was not a very common science, this code became very difficult to decipher. This kind of password can only be said to be quite safe if it is transmitted by pigeons, dogs, or people, and even if it is intercepted, it is difficult to understand.

Of course, these things are easy to say, but when it comes to real learning, it is still difficult for those Wolf's Den agents who lack a modern knowledge base. Luo Ming only taught a group of students with good understanding, so he let them be instructors and teach and train internal personnel himself.

During this period, Xiao Yu's injuries have been completely healed. The nets that He Ting had cast were also collected. He used Gu Yihe of the weapon casting battalion as a bait to secretly track and monitor all the guys who came into contact with Gu Yihe, so as to fully dig out their comrades.

After some days of investigation, they investigated all the internal and external personnel of the two groups sent by the Northern Alliance and the Eastern Alliance in an attempt to purchase the complete set of parts and drawings of the hard crossbow "Legend of the Grim Reaper".

He Ting gave an order, and with the help of the army, the Wolf's Den agents fully closed the net, and none of the enemy agents involved in these operations could escape. Now that they have all been escorted back to the wolf's den, He Ting is personally presiding over the interrogation to see if he can dig up more valuable information from their mouths.

Don't look at He Ting, who usually doesn't talk much, but he is still very good at extorting confessions and plotting rebellion. Many people were terrified when they heard his name.

Given that there were too many people coveting the casting of high-end equipment, Luo Ming demanded that the entire casting camp of Jiemur be relocated to the basement of the wolf's den. For Gu Yihe, who made the opponent suffer a big loss, in order to prevent the other party from launching a possible retaliation, he ordered He Ting to set up a set of security measures for him, so that he could avoid the limelight during this period of time.

It took Jie Muer about twenty days to create two sets of armor from Luo Ming's "Sen Luo Hongmeng Jade". One set is called "Lingyue", and the other is called "Wenhua", which is the name given by Xiao Yu. Both pieces of armor are high-level armor, and Jie Mur is deeply upset that he has not been able to explode better equipment.

Luo Ming was already very satisfied. After all, many cultivators who were much higher than him didn't have any equipment.

Since the armor of the two people was broken, Luo Ming was no longer satisfied with the quality of this armor, but hoped to get a better pair of armor.

It's just that Jiemur has guarded a Taihe iron mine for so long, but he has only played a set of ground-level armor.

This armor was later given to his father-in-law, Huagu Tea. After that, he never managed to put out a pair of ground-level armor. After all, the odds of forging ground-level equipment out of Taihe iron are too low, so low that people lose patience.

If there had been such two sets of shining armor, Xiao Yu would not have been so seriously injured. Luo Ming was thinking about it, and someone came to report that there seemed to be a problem with Duoguo Silver Beach, and the Ruan brothers asked Luo Ming to go there and discuss a solution.

Among the seven Ruan brothers, there are four in the early stage of the bone spirit, two in the middle stage, and one in the late stage. Although they are surrounded by strong neighbors, because of the unity of the seven brothers, they have been able to entrench in Duoguo Silver Beach for many years and strive to keep it safe. Could it be that there is some trouble now? Luo Ming asked the person who came to report the news in detail, but the person they sent to report the news could not say clearly, only that the thieves had attacked and harassed, and several of the seven brothers were injured and were very embarrassed, so they only asked His Highness to discuss countermeasures quickly. He also said that the boss Ruan Qingtian had an explanation when he came, and the person who delivered the letter did not need to say much, and it was best for him to report all the details to His Highness in person.

When Luo Ming heard this, he had no choice but to be taken by Xiao Yu and hurriedly set off and flew towards Duoguo Silver Beach.

Xiao Yu was already at the mid-level of the Bone Shadow at this time, and her sprinting speed was very fast, and in just a while, she and Luo Ming came to the sky above Duoguo Silver Beach.

Luo Ming looked down and saw that the beach and the village were very messy, some houses had collapsed, and some houses and fishing boats on the beach were emitting billowing smoke, as if the fire had just been extinguished. Some of the villagers were running around, not knowing what they were shouting.

Luo Ming came to the Ruan family's compound and saw that the seven brothers were all there, but three of them were lying on bamboo beds in the shade of the trees, obviously not lightly injured, and there were several people like Lang Zhong who were busy taking care of them. Each of the other four looked a little embarrassed, their clothes torn, and they were either stained with blood or blackened by smoke. He then hurriedly ordered Xiao Yu to go over and see if there was anything he needed help with.

The boss Ruan Qingtian was directing the people to make the decoction, and when he saw Luo Ming, he couldn't help but be overjoyed, and said, "Captain, it's good that you're here." His voice was still loud and full of energy.

"Who are they? were you beaten back?" Luo Ming didn't talk about the old politeness, and asked straight to the point as soon as they met.

"It was some wandering samurai from the Eastern Wai Kingdom, and it is said that they were retainers who lost their masters after the defeat. Although it is a rabble, it is quite strong in combat. Nguyen Thanh Tien said: "Most of them are stationed on an island about a hundred miles ahead, which we used to call Fairy Island, and they called it 'Tokaido'. They harassed us before you came here, but they didn't attack us very badly. During this period of time, their numbers have increased dramatically, and their combat effectiveness has increased greatly. Not only did they come to rob our fishing boats many times, but they also landed on Duoguo Silver Beach, robbed people and money, and set fire to boats and houses. They even threatened that this place had been the territory of their Wa Kingdom since ancient times, and now they would take it back. ”

Luo Ming inquired in detail about their numbers, equipment, combat effectiveness, and the types and forms of kung fu cultivation. Ruan Qingtian introduced: "The number of people who came is not necessarily, when there are more than a thousand, if there are few, there are three or four hundred, and they are equipped with a kind of sword. He asked his subordinates to take out a set of captured knives and show them to Luo Ming.
