They just couldn't get in, because the original road had been blown up by those two so-called geniuses.
Those two had already been caught. According to their statements, they got the intel from a secret forum outside, and then confirmed it offline with someone they knew.
They knew someone was coming to take revenge on Cai Qidong today, so under the excuse of hauling goods and using low shipping costs as bait, they got a job transporting fireworks from a middleman, dismantled the fireworks by hand and added their own stuff, turning it into a huge homemade bomb.
They literally drove the car loaded with the bomb onto the road leading in and out of the Domain, then blew it up, trying to trap Cai Heizi inside the Domain.
They didn't dare try direct assassination, but they also didn't want to let this opportunity slip by. When they realized more than one group was coming, they finally worked up the nerve.
