After leaving the cell of the Secret Service, Luo Zhang immediately returned to his home. Naturally, Luo Zhang did not need to worry about taking over the store. With Li Yifu and Zhao Tianhu here, this matter did not require any thought at all.

Anyway, Changsun Wuji had already signed and gave all the shops to him. Even if the people below were confused, they could not resist.

With these receiving shops, Luo Zhang's business will spread throughout the Tang Dynasty, and Li Yifu's intelligence network will also be able to extend to the entire Tang Dynasty, and even extra chapters.

After all, Changsun Wuji has been in business for so many years, and there are many spies on the sidelines, and these will all be taken over by Li Yifu and become the eyes of Li Yifu.

As for Luo Zhang himself, he continued to study his cement. After all, the cement shown to Li Shimin was just the beginning. You must know that this thing has a label. Luo Zhang wanted to make this thing have a higher label, and the city wall he built would be

Can be strong.

Early the next morning, Luo Zhang came to the Secret Intelligence Department again after attending the morning court. This time he came not to see Changsun Wuji, but to see the third prince of the Dashi Kingdom.

After asking the third prince about some things about the Great Food Kingdom, Luo Zhang sent him to the Secret Intelligence Department. Compared with being locked up in a military camp, the Secret Intelligence Department was safer.

When the third prince saw Luo Zhang, he was so excited. Being locked up in the Secret Service for the past two days, he was going crazy.

He couldn't eat well, and his sleep was full of lice. At night, he heard some prisoners howling like ghosts and wolves. Although he couldn't understand it, the sounds were really scary and made him very frightened.

When had he ever been treated like this? From a young age, he had been well-dressed and well-fed, and had been cheered and supported.

So the first time he saw Luo Zhang, the third prince burst into tears and complained to Luo Zhang, saying that Luo Zhang could not treat him like this because he was the third prince.

Luo Zhang just smiled at the third prince's words, and thought to himself, if I don't let you endure hardship, how can you say anything more.

For example, Luo Zhang asked him to draw some important ports in the Big Food Country and the sea route map to the Big Food Country. The third prince refused. In addition, he was asked to draw the locations of some important towns in the Big Food Country, as well as which ones.

After all, the generals and the army were powerful, but the third prince also refused to tell them.

In this way, how could Luo Zhang make it easy for him, he would naturally have to make him suffer.

After enduring two days of inhuman torture, the third prince could still bear it. The first time he saw Luo Zhang, he said that he would answer whatever Luo Zhang asked and tell him everything he knew.

Hearing the third prince's words, Luo Zhang showed a knowing smile. He originally thought that if the third prince in front of him didn't tell him yet, he would use some means. Now it seems that these means are also saved.

After Luo Zhang took out a map, the third prince was immediately shocked. The map drawn by Luo Zhang was so detailed.

Even as a royal, he had never seen such a detailed map.

Moreover, what is drawn on this map is actually a map of their food country and the surrounding countries.

Even they themselves may not be able to draw such a map.

Looking at the suspicious eyes of the third prince, Luo Zhang had no time to explain to him. He snorted and said: "Now point out where your important ports are, as well as some important cities, military garrisons, etc. You can

They were all marked clearly for me.”

"If there are any more untruths, I will leave you here and never care about you again. Just live here for the rest of your life!"

Luo Zhang's words made the third prince tremble. He seemed to have thought of the horror here. Without a moment's delay, he picked up the brush Luo Zhang handed him and started drawing on the map, while also marking it.

Although Luo Zhang couldn't understand it, there was someone who could understand it. While reading, he explained to Luo Zhang what the third prince wrote.

Seeing that the third prince was honest, Luo Zhang didn't say anything. When he saw a sailing route, Luo Zhang finally showed a smile.

With this route, his fleet will not have any problems heading to the Food Country.

What I want to say here is that sailing is not just something you want to do. The sea is constantly changing, and a reef can capsize your boat. Therefore, without a navigation chart, it is extremely dangerous to go on an open route by yourself, and it also requires courage.
