And only ten years of ginseng juice is enough. Of course, for better effects, Zhou Xueyao suggested that it is best to use ginseng juice that is over fifty years old.

Ginseng juice? Without saying a word, Zu Qianyue immediately ordered Xuanhuang World to collect it. Every family has grown too much ginseng. Not to mention the ones that are fifty years old, there are quite a lot of them in five hundred years.

But Zhou Xueyao still did not stop the research at hand. One research after another was discarded, and another one was started.

In fact, this kind of research is more about luck with a general direction. But at least Zhou Xueyao can point out a general direction.

After a while, the Ocean Group's aerospace aircraft carrier flew in. It flew from the Confused Jungle. It carried a lot of things.

Seeing the aerospace aircraft carrier approaching, Murong Shan, who had been silent next to him, spoke up, "Mr. Wang, I noticed that it has been so long, but no one seems to have attacked with artillery shells."

Wang Ruiyang was stunned for a moment, "These flying insects don't look big, their defensive capabilities are comparable to the peak of Nascent Soul. The shells may not be effective, but will blow them up everywhere. That will be troublesome."

"What about firing cannonballs into the Heaven-Sealing and Earth-Sealing Formation?"

"You saw our Heaven-Sealing and Earth-Sealing Formation before. It was shaky, and I'm afraid the formation would break if a few cannonballs hit it. But now, maybe we can try it."

Then give it a try. The Heaven-Sealing and Earth-Sealing Formation is an internal seal, so external attacks can enter the interior unimpeded.

Violent explosions exploded inside the formation. For a while, no effect could be seen, and only red clouds could be seen rolling. The bombs exploded one after another for half an hour, and flames gradually rolled inside the formation.

However, almost no changes can be seen in the flying insects. The number of flying insects emerging from the large formations still does not decrease.

Zhou Xueyao looked up in her busy schedule and said calmly: "It's useless. The main power of the explosion comes from shrapnel and shock waves. These things are useless against flying insects."
