"How many energy stones do you need to upgrade to Level 3?" Su Chen asked again.
Once the [Intelligent Chariot] was upgraded to Level 3, its defense and attack power would definitely increase exponentially. By then, even a Level 4 Evolver would not be able to do anything to it.
This was something he was looking forward to.
"I need a hundred Level 3 energy stones or energy stones."
"A hundred …" Su Chen muttered.
He only had thirty-seven Level 3 energy stones now, which was still quite a distance away from a hundred.
Moreover, he planned to leave the Level 3 energy stones for the [Mechanical Soldier], so he could only give up on the idea of upgrading it for the time being.
However, even if the [Intelligent Chariot] was not upgraded, its current Level 2 state was enough to sweep through an area.
After a while, he filled the [Level-Less Gatling Gun] and [Level-1 Pulse Cannon] with the remaining normal energy stones and Level-1 energy stones.
In addition to the energy stones that were originally installed, the [Level-Less Gatling Gun] now had more than ten thousand bullets.
It was enough to wipe out a small zombie horde.
Then, Su Chen took out an [Upgrade Gem].
Now that he had a Level 3 energy stone, it was time to upgrade the [Mechanical Soldier] to Level 3.
After using an [Upgrade Gem], the [Mechanical Soldier] was successfully upgraded to Level 3.
The Level 3 [Mechanical Soldier] was still about two meters tall, but its body was much stronger than before.
Thinking about how the [Mechanical Soldier] was made of metal, its defense would definitely be much stronger than an Evolver of the same level. It might even be a little stronger than a Level 4 Evolver.
Therefore, the true combat power of the [Level 3 Mechanical Soldier] was actually comparable to a Level 4 Evolver.
After that, Su Chen put the Level 2 and Level 4 energy stones into his storage bag and found a place to rest.
After resting for a night, the next morning.
Su Chen and the others left the mountain range full of energy.
The moment they walked out of the mountain range, Su Chen took out the [Intelligent Chariot] and made it fifteen meters long.
The current limit of the [Intelligent Chariot] could reach fifty meters, but Su Chen felt that they did not need too much space with just the few of them.
Moreover, the bigger the [Intelligent War Chariot] became, the more energy stones it would consume. There was no need to waste them.
As soon as he got into the car, a red light flashed on the central control panel and an alarm sounded.
"Warning, five kilometers ahead, a large number of zombies have been discovered. Estimated to be more than ten thousand, they are rapidly approaching us."
"A small zombie tide?" Su Chen murmured as his eyes lit up.
He had originally planned to head to Blue Moon's colony to hunt zombies, but he never thought that the zombies would actually take the initiative to come to him, saving him a lot of time.
The other people were also shocked. They were eager to try, as if they were looking forward to the arrival of the zombies.
If it was in the past, when they heard that ten thousand zombies were approaching, they would have run away immediately.
However, things were different now.
Now that their strength had greatly increased, they were full of confidence in themselves.
More importantly, they were with Su Chen.
There was no need to mention Su Chen's strength. Coupled with the powerful firepower of the [Intelligent War Chariot], not to mention dealing with a small zombie horde of more than ten thousand.
Even if they were to face a medium-sized zombie horde of more than ten thousand, they would still be able to fight.
"Get ready. When the zombies come later, you guys will kill them with me," Su Chen said.
Killing zombies could increase their combat experience, and they could also quickly consolidate their cultivation. Su Chen was also thinking for them.
Of course, the prerequisite was that they had the [Soldier Recruitment System] and were bound to each other.
No matter who killed the zombies, there was a chance that a fragment would drop.
Otherwise, he would really have to think about it.
"Chen Ge, can we also kill zombies?" Yang Hao's eyes lit up. At the same time, he had some doubts in his heart.
In the past, the job of killing zombies was done by Su Chen alone. Why did he agree to let them do it together this time?
