1. First find the Plants vs. Zombies 2 app and click to enter the game.
2. Next, we need to obtain the primitive pea plant first. We can select the Dino Crisis world map, and then click on level 5. After successfully passing the level, we can obtain the first-level primitive pea.
3. Next we need to upgrade the first-level peas to the fifth-level. The main requirements are original pea fragments, gold coins and culture fluid. Among them, the original pea fragments are relatively difficult to obtain. Generally, we only have four ways to obtain them. The first is to obtain them in a lottery, but this method has a low probability and is slow to accumulate.
4. The second type is obtained in the challenges of Giant Crisis and Evil Invasion, but the accumulation of fragments in this way is very slow.
5. The third method is to redeem original pea fragments in the battle exchange store, but this method depends on whether the store has refreshed such fragments, and the accumulation speed is not very fast.
6. The last one is obtained in Penny's shop. Penny's shop will refresh plant fragments every day. If original pea fragments appear, you can buy them in large quantities and quickly obtain enough original pea fragments, but the price will be a lot of gold coins.
7. After accumulating enough original pea fragments, you need to purchase level 5 nutrient solution. This can only be purchased in the endless store of Endless Challenge, and level 5 nutrient solution requires 10 bottles and a large amount of gold coins. After accumulating enough, you can upgrade to get the fifth-level original pea.
