Those who didn't grab the holy medal felt a little regretful. They slapped their heads and regretted why they were not as smart as the bald man. The first person ate the crab, and those who wanted to imitate him didn't even get any soup.

There were also holy tablets dropped by two people after their deaths lying in the open space outside the city. A circle with a diameter of dozens of meters was formed outside the holy tablets. This time, no one rushed over to pick them up. Too many people died, and the only ones left were those with brains.

The fighting outside the city stopped. Any warrior who wanted to enter the city would be attacked by thousands of contestants. Only those who had the strength to hold on were allowed to enter the city. Ordinary martial arts masters did not dare to say that they could definitely rush in.

After two days of stalemate, everyone's spirits began to relax. People always get tired, and it is impossible to keep fighting without replenishing their energy. At this moment, the two pieces of ground where the holy cards were placed suddenly collapsed, like an earthquake.

The holy medal fell into the hole in the ground and was grabbed by someone and dragged into the hole.

The people guarding around reacted one after another, and the light of martial arts and spells flew over, covering the place where the holy tablet was. The attack lasted for several minutes before stopping. When the smoke and dust cleared, a black cave appeared on the ground.

"These tunnel diggers took the holy medal!"

Many people cried out in frustration. They weren't angry that the holy medal had been taken away like this, but that they hadn't thought of this method. They dug a tunnel inside the city to where the holy medal had fallen, and then escaped back to the city through the tunnel after obtaining it. Sure enough, there were many geniuses with high IQs among the contestants!

Everyone outside the city was thinking, now that the holy medal is no longer in sight, how can the person holding the holy medal enter the city?

"Everyone, use the life detector to check underground. No life can be allowed into the city!" A smart contestant suggested.

When the strength is similar, it is a confrontation of IQ. No matter whether it is human, orc, or monster, they are all living beings and can be sensed by high-tech life detectors. Now those who want to secretly dig tunnels into the city from a distance will have no way to do it!

Many people did not have detectors, but that was a big deal. Some people spent more than ten minutes running to the neighboring city to buy a lot of equipment and threw them all to the people outside the city. The rest were smart people and knew that the priority now was unity, not infighting.

Countless people were searching everywhere outside the city like restless ants, and attacking underground with sword energy and magic.

Now the creatures outside Hanfeng City were in trouble. Countless snakes and poisonous insects hibernating underground were strangled to death underground, and countless tiny bald heads disappeared from the life detectors.

"Why do we have to kill small animals like ice snakes and mice?" A contestant with freckles on his face didn't understand and asked the people around him. He thought it would be enough to kill the larger animals on the life detector.

"Because the competition involves the Holy Medal, they might hire an animal communicator or something like that. They'd tie the Holy Medal to a snake or rat, and have these small animals carry it into the city through a burrow." The person next to him explained, "You need to think carefully. Most of the people chosen to participate are top talents in their countries, and they have very high IQs! Besides, controlling small animals isn't that much of a talent; it can be controlled with high-tech chips."

The people around suddenly understood after hearing this explanation.

Everyone dispersed and continued to eliminate the dangerous creatures underground.

Half a day later, all the small dots under the ground detected by the life detector had disappeared.

In fact, the detector has a distance depth, which is 10,000 meters. If the small animals dig a hole 10,000 meters underground, they will be helpless. But this is simply impossible, because there are rock layers thousands of meters below, and ordinary small animals cannot get through at all. Besides, the control distance of the communicator is only one kilometer at most.

After the people guarding outside the city eliminated all underground life, they began to rest and wait, not allowing anyone to enter the city.

The freckled man who asked the question also sat on the ground to rest, but nothing happened all day. The next day, his mind seemed to open up, and he suddenly remembered that the owners of the holy medals had another way to transport the holy medals into the city without having to control the small animals!

"Oh no!" the freckled man jumped up and shouted.

The people around him looked at him, not understanding why he was going crazy?

"The contestants who get the holy medal don't have to put it on any small animals. There are ways to transport it into the city!" said the freckled man.

"What method?" The other interceptors didn't understand and asked.

"We have fallen into a misconception, thinking that only living, vital animals can smuggle the holy medal from underground into the city!" the freckled man reminded.

"Ah——" The people around slapped their heads, thinking that they were negligent and missed something!

"That's right. With technology so advanced these days, they could easily build a small, unmanned earth-drilling machine or robot, equip it with remote control and infrared night vision, attach a holy medal to it, and drill into Hanfeng City through the existing underground caves!" said the freckled man. "Even if there aren't any existing caves, they can always get more earth-drilling machines to dig holes! Maybe they did it on the first day, out of our sight!"

All the contestants who were defending the city and intercepting the robots were suddenly excited. They were indeed negligent. Inanimate robots could indeed do this kind of thing, and do it better than mice and snakes!

"Quick, everyone, get some signal jammers and disrupt all the signals outside Hanfeng City!" Many people reacted and immediately came up with a solution. "Disrupt their remote control signals!"

"Maybe their machines have anti-interference devices." The freckled man said, "Also, they probably have already transported the holy tablet into the city!" He was a little discouraged. The defenders are always at a disadvantage because they have to find the opponent's invasion or attack method before they can formulate defensive countermeasures. This means they are one step behind, and they fall behind step by step.
