After agreeing to Chen Haoran's request, Yi Tian went back to continue his study. However, Bai Siyang stayed this time to occupy a place and directly began to learn the way of array with himself.

As for the other place, it was reserved for another disciple of Chen Haoran. Although he was still crouching in the Seven Star gathering spirit array, Chen Haoran also directly reserved a seat for him.

Yi Tian is not wordy about this. What he has to do during this period is to understand the structure and operation mode of the Sky Patrol warship first, and then design the most suitable defense array according to local conditions.

Time flies by. Yi Tian stayed for half a year in the weapon smelter alliance. Later, when the warship started construction, he moved directly to the airport of sunset city.

On one side of the airport, the existing "sunset" is moored. Now the new ship to be designed is called "Chaoxia". According to the requirements, the tonnage and volume are slightly higher than the original one.

The construction of the sky cruiser is not a trivial matter. Although the project is undertaken by the alliance of weapon refiners, at least 70% of the people who come to fight in the whole airport are still from the city master's house. Even Yi Tian saw that Hong Fei, who was in charge of public security in the city, came several times, and then those members of his team took turns to maintain vigilance.

The construction of the whole warship will not happen overnight. This time, Yi Tian proposed to engrave the guard array on the keel of the warship. In this way, relying on the strength of the keel, the power of the large array can be increased to as much as 50%.

Then, a composite defense array was arranged. When the Sky Patrol warship was built to a certain extent, one time of the defense array was engraved on it. It was not until the final completion that the combined defense array on the whole warship was completed.

However, this effort also paid off. Five years later, when Chen Haoran went out for trial voyage in a new warship, all the people involved in the design also sat in the cabin.

Yi Tian watched Pei Yuexiao control the warship to sail rapidly in the air for some time in the main control room. He didn't arrive at his destination until three days later. The first test is speed. I hastily estimate that I can almost achieve even if I fly at full speed. The advantage of the Sky Patrol warship is its strong endurance. If I fly like this for more than ten days, I'm afraid I will affect the escape speed because of my lack of spiritual power.

But as long as the warship has sufficient energy supply, it can maintain such a stable situation for a long time. Next, the second item is the defense test. Naturally, the test object is the elder Chen Haoran.

After the people flew out of the cabin, Pei Yuexiao directly controlled to open all the defense arrays. At this time, in the distance, he only saw a thin light film on the whole more than 100 Zhang Long warship.

When Chen Haoran saw it, he just frowned, as if it was different from his imagination. He turned his head and asked, "Yi Daoyou, can your defense array withstand my full strength?"

"Old Chen will know as soon as he tries, let's wait and see," Yi Tian replied faintly with an indifferent look.

Later, I saw Chen Haoran's hands together, and the red flame cleaved towards the Chaoxia. In the distracted period, the power of the monk's magic was fully felt when he stood 30 feet away. The momentum is twice as strong as when you try your best, but the red light is absorbed directly after concentrating the defense film on the front.

The warship didn't seem to shake for a moment. Then Chen Haoran was happy to see the hunter, and his hand kept attacking for a quarter of an hour, but his magic was either bounced or absorbed. In the end, he didn't break the warship's defense.

So far, the experiment came to an end, and then the Chaoxia carried everyone back to the sunset city. At this point, the task of the weapon smelter alliance was successfully completed, and Yi Tian could be sent away later.

In recent years, bringing Bai Siyang and others around can also be regarded as teaching them some array methods. Similarly, Chen Haoran saw it in his eyes and finally gave a generous gift. In addition to 2000 merit points, there are a large number of spirit stones and precious materials as compensation.

Now Yi Tian has ordered his own materials on hand, and the materials from the later stage of practice to the distraction period are basically complete.

Yi Tian is not in a hurry to go home after he got out of the weapon smelter alliance. The sunset city has changed a lot in recent years. Taking advantage of this opportunity, he can stroll around the city and collect valuable materials.

If you want to buy and sell rare materials, you still have to go to the two big shops in the city. Naturally, it goes without saying that the Hong family is an old customer. Every time I go shopping, I get a lot of discounts, some of which are basically sold directly to myself at the cost price. In the long run, I'll be a little embarrassed.

Now Yi Tian doesn't want to go to Jubao building. It's not a matter to always receive favors. Then he turned around and walked towards the Tongtian Pavilion. He thought that the things there were not bad, and that he was a man of small value, not bad for those spirit stones.

The key is that there are also some prefecture level treasure materials in Tongtian Pavilion. In that year, Ji Wen insisted on not selling because she had no background. Now we can try to say that.

After thinking about it, he went straight to Tongtian Pavilion. Half an hour later, he came here and found that the guys outside the door had changed. It is estimated that after a hundred years, these original people's longevity yuan will be almost consumed.

When I came to the store, I was directly received by the third shopkeeper. After asking, I learned that there happened to be an auction in the city today. But all those with some wealth go there to play the autumn wind. As for this auction, there is no distinction between high and low levels. Monks compete in the same venue from the foundation construction period to the God transformation period.

Yi Tian has some doubts about this. In previous years, he separated the auction to avoid the adverse impact of high-level friars. But it's mixed up this time. Can the city Lord's residence really hold the scene.

After telling the questions in his heart one by one, the third shopkeeper of Tongtian Pavilion replied with a smile: "I don't know. This auction is the first time held after the new inspector general took office. There is also news from the city master's house. This auction also represents the new image of sunset City. We want to expand the influence, so we combined the original two games into one."

This is not only the stability and prosperity Hong Shanhe wants to show, but also the opportunity to investigate the ability of the new chief inspector. Yi Tian feels excited when he thinks of this place. How can he miss such a grand event. After thinking about it, he said goodbye directly, and then went straight to the auction mall in the city.

Before coming to the auction, I saw a sea of people here and a long queue outside the venue. Yi Tian won't queue up like them. When he was swept away, he found Mi Jun leading the team to maintain order outside the gate. Then he quietly touched it and whispered to him in private.

The latter was also happy, and then took out a quick token and gave it to his men. So Yi Tian took his light and went directly to the elegant room box on the third floor.
