Lu Qing'an found that his observation method was useless, because at this moment the sealing formation was suddenly upgraded. Not only did the expansion and contraction speed double, but it also completely isolated the life of the magic dragon.

He couldn't determine whether the dragon was about to die by looking at how much life force it had left!

If he took action at this moment and failed to completely kill the dragon, he would have missed this opportunity completely!

After all, he couldn't set up the next formation in a short time.

Lu Qing'an looked at Xu Qingying.

Xu Qingying was also very anxious. She had not yet developed any intuition, and the dragon was already in a terrible state.

She even doubted whether the evil dragon was dead, but she heard from Lu Qing'an that strange phenomena would appear after the evil dragon died.

It means that the evil dragon is still holding on and not dying.

Another stick of incense passed.

Lu Qing'an took a deep breath and made a decision.

The main thing is that the dragon was almost completely crushed!

Even with the strongest defense of this demon dragon, it would not be able to withstand the self-detonation of so many of his treasures.

"No more waiting!"

Lu Qing'an gritted his teeth and had no choice but to take a gamble.

Don't wait until the time comes and do nothing, and watch the dragon die, which will make him feel even worse.

Now if he directly tries to give the dragon a final blow, there is still hope of success. Even if he fails, he can still accept it, at least he has tried his best.

Just as he was about to detonate the treasure, Xu Qingying suddenly grabbed his hand tightly.

"Here it comes! Here it comes! Just one more stick of incense!" Xu Qingying felt Lu Qing'an's determination and said anxiously, sweat already oozing out of her palms.

Lu Qing'an sensed her nervousness, but he was more ecstatic at the moment. Xu Qingying's intuition had never been wrong, which meant, it was a sure thing!

"Okay!" Lu Qing'an instantly calmed down and adjusted himself very quickly. Just wait another stick of incense!

He silently counted the time in his mind, his consciousness extremely clear counting every second, staring at the dragon intently. At this moment, he didn't even realize that he was still holding Xu Qingying's hand.

Finally, the last ten breaths of time arrived.

"Very good! Explode for me!" Lu Qing'an acted quickly, sacrificed the treasure, and projected it into the formation, using the powerful spiritual energy to project the formation into the seal.

The formation passed through the seal that had just expanded and touched the dragon's broken body.

Boom!!!
