Zhang Xing knew that the power of six dragons alone was not enough to fight against the entire Foss Kingdom.
Therefore, he put most of his energy into the lottery system.
Every few days, he would draw twice, accumulating general EXP, hoping to draw a few more dragon eggs.
In the remaining ten lottery chances, he could draw three or five in a row.
The first time, he drew 10,000 experience points. The second time, he drew three in a row. After that, he drew nothing for a few more times.
For more than half a year, he repeatedly drew the lottery. The God of Luck did not give him much, but it finally gave him something.
He drew a total of four dragons — a red dragon, a blue dragon, a green dragon, and a gold dragon.
After upgrading these dragons to rank-7, he was left with more than 383,000 experience points.
Of course, every time a dragon was upgraded to rank-7, the system would reward him according to the number of upgrades.
For example, if the red dragon was the eighth to be upgraded, the system would reward him with 80,000 experience points, and so on. If the gold dragon was the eleventh to be upgraded, the system would reward him with 110,000 experience points.
Other than Jin Bao, Zhang Xing had ten rank-7 dragons that could fight.
In addition to his overall combat power, he believed that the Foss Kingdom's emperor would have a headache.
Zhang Xing also wanted to draw a few more dragons, but he only had one lottery chance, so he kept it.
That was all he could do at the moment. He also did not think of using these forces to attack the Foss Kingdom's palace.
Besides, he could not possibly destroy the kingdom just because he was afraid of their revenge after killing their crown prince.
Attacking a fourth tier empire was an arduous and unrewarding task. He wouldn't do it because it was impossible to take it down.
Only when he was strong enough to make his enemies fearful would they not dare to act rashly. Just like those fourth-class kingdoms, where the power was balanced, no one dared to go to war.
Also, there was the remaining 383,000 experience points.
He was still 70,000 experience points away from upgrading a dragon to rank-8.
Similarly, it would also allow him to upgrade from mid-level to high-level Emperor.
However, he did not consider upgrading himself. Once he drew another dragon, he would upgrade Black Treasure to rank-8 without hesitation.
He had already planned the upgrade path, which was to aim for the upgrade mission given by the system.
He believed that anyone could figure out what was going on.
"Let's go back and take a look. Take a look at Na Bao and some of our friends in Redbud City."
Zhang Xing had originally planned to peacefully develop in Redbud City. However, after killing the Crown Prince and after half a year of thinking, as well as understanding the strength of a Grade 4 Empire, he changed his mind.
The strength of a third tier country was too weak. If they wanted to develop, they would have to go out and go to the fourth or fifth tier empires to find more resources and make more friends.
…
Na Bao leaned on the table and looked at the moonlight outside the window.
"Zhang Xing, today is your birthday. I remember clearly that on this day last year, I heard a beautiful melody at the Thousand Snow Peak."
"…"
Na Bao was immersed in her memories and unknowingly fell asleep. A happy smile gradually appeared on her face.
But not long after, her brows knitted together, and her smile was no longer there. It was replaced by an indescribable sadness, and two lines of tears flowed down from the corners of her eyes.
"Zhang Xing … Zhang Xing …" She muttered.
Zhang Xing let out a long sigh in the darkness. He did not disturb Na Bao's beautiful dream.
As long as you are safe!
Redbud City, in Solina's room, Tina, Cher, Faye, Saiya, Keldo, and the others gathered together.
"I believe that Zhang Xing is definitely still alive. He doesn't want to implicate us. Don't worry, he will appear one day, and he will be …"
Solina displayed her excellent qualities as a mentor and patiently advised them.
