I found that there is an arbitrage loophole. Hackers only need one Gobbler. When the liquidity of goo is large enough, they use flash loans to buy a lot of goo from the market, and then go to mine with Gobbler, dig the goo and sell it immediately, and then repay the flash loan, Use the profit to mint Gobbler, and then continue the flash loan to continue the above operation, the cycle can use up the liquidity of the market goo and mint a lot of Gobbler
