In fact, Sun Tu's duty is not only to train the Tiger Army, but to find out and arrest the Liao State spies hiding in Bianjing City, but the investigation of Zhou Dong's death and Zhou Xiong's murder has nothing to do with him, and everything can only be done in secret.

But in fact, what Sun Tu really cares about now is finding out the truth about the murder of his master, as for the Liao State spies, he also has arrangements, but he is not too concerned, and only sends a few brothers from the former Shandong Army scout camp to keep an eye on the bow and crossbow courtyard to see if he can find some clues from it.

Because as far as he could tell, those crossbows should have flowed out of the crossbow courtyard. After all, there are only two ways to get weapons such as bows and crossbows in Tokyo, either the forbidden army or the bow and crossbow courtyard. The bows and crossbows of the forbidden army are all engraved with numbers, but those bows and crossbows that have been found have no relevant markings, so they can only come out of the bow and crossbow courtyard.

It's just that Sun Tu hasn't had time to check the situation in the bow and crossbow courtyard, and his right to investigate the case has been deprived. Of course, even if he had the right to continue to investigate the case, I am afraid that it would be difficult to arrest and search people in the crossbow courtyard like he did with other officials, because the status there was too special for ordinary officials to enter.

To make a similar analogy, the Bow and Crossbow Institute is equivalent to a scientific research department specializing in weapons of mass destruction after a thousand years, where there can be too many weapons and related documents related to the entire national security, and the leakage of any details of the bow and crossbow is a great threat to the official army of the Great Song Dynasty. Therefore, only the officials in the bow and crossbow courtyard, or those who hold the special decree of the Son of Heaven can enter it, and the others, that is, Cai Jing Gaoyu, are difficult to enter.

Therefore, even if Sun Tu had doubts about it, he could only send people to keep an eye on it and find out if there were any strange people among them. And this arrangement finally came to fruition today, and after a few days, people really discovered some strange performances of the crossbowman named Cheng Fang - for example, every day after leaving the yamen, he was not in a hurry to go home, but would go to a hotel two blocks away from the bow and crossbow courtyard to sit for a while.

Another example is that although he will order wine and food there, he will hardly move the wine and food when he leaves, so it is obvious that he is not really going to drink. It is even more doubtful that every time he enters the hotel, a guest enters the hotel and sits at a table not far from him. Although the two did not get together, they could obviously communicate in a whisper.

All this is enough to prove that there is a problem with this Cheng Enlargement, and it is likely to be related to the bows and crossbows that fell into the hands of the Liao spies. After confirming this, these scout veterans quickly returned to the Imperial City Division and reported the suspicions to Sun Tuyu.

And after Sun Tu figured out the situation, his face became solemn again: "It seems that those Liao spies are really as I thought, they are not willing to leave empty-handed, and they are still trying to get the bow and crossbow again." Can they follow their dwellings? He believed that with the shrewdness of these men, it was naturally impossible not to follow each other.

But the result made him a little disappointed: "General Hui, although we followed, those guys were too cautious and cunning, and they were thrown off by tricks every time." Saying that, the soldier who came to report was still a little ashamed.

Sun Tu didn't blame him, and said with relief: "It's no wonder to you, after all, since the other party can be sent to Tokyo to do such things, they must be good hands." And when it comes to familiarity with the city of Tokyo, you can't compare to them who have been here for many years. ”

"And what is the general going to do with them? Do you take people directly? Di Yingyang asked with concern.

"No, there is no evidence for such a person, it will only startle the snake and ruin the whole plan. What's more, this matter is eighty percent sure that Cheng Fang stole the bow and crossbow, if it wasn't for him? Sun Tu thought for a moment before deciding: "Just be more patient, until they really hand over the bow and crossbow or something, and then it's not too late to do it." When the time comes, people will get the stolen goods, and they will not be afraid that they will not admit it. ”

Speaking of this, Sun Tu looked at the sun outside that was gradually turning west, and said, "Look at the time, it's almost time for the bow and crossbow courtyard to disperse, right?" Let's go, I'll also go to meet this Cheng Fang and see how he connects with people. Since the clues of Zhou Xiong's case are almost broken, he thought about solving the matter here first, which can be regarded as adjusting his mood.

Di Yingyang was also very interested in this, and immediately asked to follow. After Sun Tu nodded, he didn't delay, and quickly went straight to the bow and crossbow courtyard under the guidance of the scout, and after half an hour, he appeared on a two-story restaurant facing the street.

"General, this is his daily journey, and every time he picks one of the hotels to sit in for half an hour." The scout whispered an explanation as he looked at the end of the long street. And when Sun Tu nodded, this person said a little excitedly: "It's here." ”

Sun Tu looked down in the direction of his finger and saw a middle-aged man with an extremely ordinary figure walking slowly, and when he got closer, Sun Tu could even see that his face seemed to have a little uneasiness, and his hand in his sleeve was also a little stiff. This made Sun Tu's eyebrows suddenly raised, things wouldn't be so coincidental, could there really be something hidden in him?

Then, Sun Tu turned his gaze around him again, and soon found that there were several people staring at his every move, but these people were all scouts under him, and there was no trace of the Liao State spies as he imagined. Isn't it that people have already entered the hotel and waited?

Sun Tu thought about it, and he was even more energetic, paying attention to the direction of the other party's travel. Then there was an unexpected scene, the other party did not enter any of the hotels in this row, but kept moving down the street.

"This ...... General, he used to stay in one of the hotels for a while, but how did it change today......" The subordinate was also a little confused, and muttered a little uneasily.

"I'll talk about the rest later, but keep up with him first. If something goes wrong, there must be a reason. Sun Tu looked quite calm, got up quickly, leaving one person to pay the bill, and he led people downstairs quickly, and then stayed far behind Cheng Fang.

Fortunately, there were a lot of pedestrians on the street at this time, and the dozen or so people in their line did not seem too abrupt, and that Cheng Fang was not too alert, and he had thoughts, so he was followed all the way by them and didn't realize it, just caring about his own way.

It's just that as he bends left and right, soon, it's not easy to follow. Because he had bent into a rather remote alley, even a fool would be able to see the problem if more than a dozen people were chasing after him. And the scout frowned even more: "This is not the way to his house, why did you suddenly come to such a remote place?" ”

"If you think about the unrighteousness, you can only know the truth by looking at the past." Sun Tu said, and waved his hand: "You guys are guarding here, and then let a team of people detour to the other end to watch, and Brother Jiu and I will follow up to see and understand." ”

"General, this is a little inappropriate, it's better to let the little ones in." Someone hurriedly objected, but Sun Tu waved his hand and denied it: "What, can you be stronger than me in terms of skill?" What's more, Brother Jiu and I are the most unnoticeable in our outfits. ”

It was only after he said that the people understood. Indeed, Sun Tu and Di Yingyang are both dressed in brocade robes, and they look extravagant, and no one will doubt that they will follow people. However, these scouts, all of them are short-dressed and capable, and once they lose the cover of the people on the same road, it is too easy to show their flaws.

The situation was urgent, Sun Tu didn't give them more time to hesitate at all, and immediately pulled Di Yingyang, who was a little apprehensive, to walk inside. The latter suddenly showed a bitter smile on his face: "San Lang, don't hurt me." To tell you the truth, although I have been in the army for many years, I can talk about my skills, but I am very loose. ”

"Brother Jiu, don't worry, it's not for you to take people, just follow and see what the hell this guy is doing. And with me, I will be able to protect you. As they spoke, the two entered the alley. Fortunately, they followed fast enough, and they were able to follow after Cheng Fang turned a corner into a bamboo forest.

At this time, it was quiet here, and there was no half of a figure in sight, only the three of them were walking into the depths of the forest. During this period, the crossbowman still seemed to look back vigilantly, but how could he find out that Sun Tu had been successful, after a few glances, it was just a waste of time.

He didn't stop until he came to a large bamboo tree the thickness of a human waist, and then bent down and worked for a while, as if he was burying something. After a long while, the work was done, and then, as if relieved, he hurriedly turned around and walked back quickly.

Sun Tu and the others had already avoided the darkness on the other side at this time, and he naturally didn't notice anything. After he walked away, Sun Tu was no longer busy following, but walked quickly towards the big bamboo. If it was eighty percent sure before, now it is nine out of nine that this person is the culprit of the leakage of the bow and crossbow, and he must have buried something important here. And just looking at the way he has traveled this way, it is obvious that he has not done this once or twice!

Although the sky was completely dark, it did not affect Sun Tu's eyesight. When he got closer, he saw a few stones on the ground that had been deliberately arranged. Immediately he took it to heart, took it away again, and with his bare hands, he soon dug a shallow pit in the mud and revealed a box hidden inside.

Sun Tu hurriedly took it out, and when he opened it, there was another scroll inside. When I opened it again, I finally saw what was drawn on it. At this moment, even he didn't realize that his face changed, and Di Yingyang, who came up on the side, was even more shocked and shouted: "The crossbow blueprint ......"
