Obtaining a Large Amount of Solar Energy in Plants vs. Zombies

Half an hour after the Double-Headed Sunflowers began growing, they could be harvested.

After half an hour, the Double-Headed Sunflowers on the Big Tree harvested solar energy.

[+630 Solar Energy (increase of 530%)]

It was that ridiculous: a single Double-Headed Sunflower on the Big Tree could harvest 630 Solar Energy every half hour.

Since the Double-Headed Sunflowers had a three-minute growth cooldown, the second one to grow harvested solar energy three minutes later.

[+630 Solar Energy (increase of 530%)]

Every three minutes, the Big Tree could harvest 630 Solar Energy.

The same thing happened with Tree Two's Great Tree.

Half an hour after the first Double-Headed Sunflower was planted, it harvested solar energy too.

[+220 Solar Energy (increase of 120%)]

The sunflowers on Tree Two absorbed only 120% more Solar Energy, so they harvested just 220 every half hour—far less than the 630 absorbed by the sunflowers on the Big Tree.

Three minutes later, Tree Two's second sunflower also harvested 220 Solar Energy.

And so, every three minutes, both of Wang Yu's Great Trees received a steady stream of Solar Energy.

The Big Tree had 88 Double-Headed Sunflowers, while Tree Two's Great Tree had 89.

It took Wang Yu more than four hours to grow Double-Headed Sunflowers on both Great Trees.

Meanwhile, Wang Yu's Big Tree kept eliminating the zombies around it.

It had wiped out every zombie within two kilometers that the Watermelon Pitchers could attack.

Of course, countless more zombies were closing in from farther away.

As soon as they entered the Watermelon Pitchers' attack range, they were all eliminated.
