After cultivating for about half a month, before Tang Ye began to discuss the attack plan for the next city, there was bad news from Liang Xue's side.

That is, when they attacked the Longboard City in the east of the Steel City, the Steel City was attacked by someone and almost lost.

Liang Xue had to withdraw his troops to help, and finally spent a certain amount of effort to defend the steel city with the help of Hou Yi.

But because of this, he suffered heavy losses, and he could not attack Longboard City again in a short time.

Regarding this matter, Tang Ye wrote back to comfort Liang Xue, without any intention of blaming, and asked him to guard the battle line and wait for him to suppress the two cities and unite them.

Obviously, in the face of the attack of the two fronts on Tang Ye's side and the three fronts on Jiang Yao's side, this Zheng Ting was still able to sneak attack the city behind him with his free hand, this was by no means Liang Xue's carelessness, but this Zheng Ting did have the ability, and there were many capable people under him.

Tang Ye had been speculating about why the Zheng Jin Force's mechanical skills had developed so rapidly, and he had also created all kinds of strange things, and he suspected that there was a Tianzong wizard who was secretly helping them.

And this should not be the help of the Taisong faction, after all, the Taisong faction looks down on the virtue of mechanical arts, and will only directly attack for the sake of interests, and it is impossible to leak any core secrets.

And now Zheng Jin's forces are divided into three, but Zheng Ting is still the strongest one, in addition to his strong personal command ability, it must be the Tianzong wizard who is good at mechanical techniques who also supports Zheng Ting.

Otherwise, no matter how strong Zheng Ting is, in the face of enemies in four directions, there will never be a chance to fight back, and it is already very difficult to defend the front without being defeated.

In this way, in addition to the great enemy of the Taisong faction, this Zheng Ting's genius is also a problem.

Moreover, the core of his technique is so beyond the thoughts of this period, Tang Ye guessed that this person may also be a traverser from the earth, and he also has a high level of intelligence and education in the system!

Although it was just a guess, the more Tang Ye thought about it, the more he felt that it was very likely.

So he called Liu Lin, the captain of Liu Pei's special force, and asked him to lead a few people to infiltrate Zheng Ting's forces to find out about this person.

The ugly man, who hadn't taken on a special task for a long time, was very happy, so he personally selected a few shrewd and capable soldiers, and left Yucheng with Li En, who was good at "clever hands", and went to Zheng Ting's territory.

Tang Ye's highest instruction to them was "Safety is more important than anything else, and on the premise of ensuring their own safety, carry out the task of news investigation."

This undoubtedly moved the two of them and was full of energy.

…………

In April 2592, Tang Ye began to discuss the plan of attack on Yixue City in the east of Yucheng.

In the military council building, Tang Ye looked at all the capable subordinates, and said in a relaxed voice:

"I heard that this art city is a special city, and there are all kinds of talented people in it. It's also a paradise for criminals. ”

"The lord of the city has given this group of people enough freedom not to break the law and commit crimes, and in the event of an invasion by foreign enemies, everyone must help the army to resist."

"Therefore, ordinary people in this city do not dare to move in at all, and there are murders from time to time."

"Now that we are going to take this city with only 40,000 defenders and thousands of strange people, can you be confident?"
