The Caohu encirclement plan, which is expected to be completed in one year, was completed ahead of schedule in only half a year. It's just that the wall has only been built to the extent that it is 70 meters high and 30 meters thick, and it needs to be further widened and heightened inside.

After half a year of construction and war, everyone has found that the 100-meter city wall built is not as reliable as imagined. Therefore, after the unanimous decision of the high-level, the wall continued to expand, strengthening the thickness of the wall from the inside, and continuing to increase the height of the wall from the head of the wall, so that the city wall became a super giant wall with a height of 150 meters and a thickness of 120 meters.

The original 50 to 100 meters of internal passage was also completely filled in, and was replaced with a five-layer automatic artillery fire end of 100 to 150 meters. As soon as the order is given, a hideous cannon will peek out of the wall.

The first floor is equipped with electromagnetic guns, the third and fourth floors are erected with Gauss guns, and the fifth and top floors are erected missile launch pads.

The Gauss Cannon, similar in style to the Electromagnetic Cannon, but is a more powerful evolutionary version. The highest rate of fire can reach 7,000 rounds per second, with an average rate of 3,000 rounds per second.

The missile launch pad is like a porous rocket launcher, similar in style to the Patriot defense missile launcher in Red Alert, which can quickly fire hundreds of various missiles in an instant. The main fire is a plasma lava projectile, and after the target is hit by a plasma lava projectile, it will be burned by the exploding plasma, and the temperature of the plasma reaches 10,000 degrees.

The battle robots on the city wall are holding RS-009 Gauss rifles, in a row of ten, patrolling back and forth neatly.

---------------------

In the blink of an eye, it has reached the end of the year, and the atmosphere of the New Year in the base is very strong. The outbreak of the virus crisis has made the earth's air pollution very serious, and this year's winter is also exceptionally cold, even in the south began to snow.

However, God still has eyes, and there are no snowflakes on the day of the Chinese New Year's Eve. Sweeping away the continuous haze, the sky is indeed clear today.

"Oh, daughter-in-law, why don't you stay in the house?" Liu Long looked at Yang Jing who came out of the mountain villa with a big belly, and hurriedly stepped forward to help.

"you! I'm not going to give birth soon. It's you, you don't care about Sister Guan at all, you're already two months pregnant, and you're still running around with the engineering team! Yang Jing was more than seven months pregnant, but she didn't look so bloated, and she sat on a chair with a plate of fried potato chips and began to count down to Liu Long.

"Hehe, say it when you come back, say it when you come back." After being reprimanded by Yang Jing, Liu Long just opened his mouth and was stupid, and his hand had already reached out to the potato chip plate that Yang Jing brought out.

"Smile and smile, you know giggle, can't you change someone to get that planting science and technology park?" Yang Jing directly knocked off Liu Long's hand that was reaching for the potato chips, and continued to count at him.

"Isn't there no way, Ling Fei can't spare his hands at all because of the construction of the wall, so didn't she let Guan Ying take a look. Besides, how important it is to plant a science and technology park, which is related to our future food problems. Liu Long didn't care about being beaten by Yang Jing, and continued to reach out and grab the potato chips and put them in his mouth, eating while talking.

Yang Jing looked at Liu Long's appearance, and he didn't smile, nor did he laugh.

"Okay, daughter-in-law, if she wants to be busy, let her be busy, as long as the person is fine. She's not a one- or two-year-old anymore, she'll take care of herself. Liu Long was eating potato chips while comforting Yang Jing beside him.

---------------------------

The sound of gunfire resounded in the bridge barrage, and the electromagnetic cannon and Gauss cannon sprayed countless bullets at the hordes of nuclear mutant zombies outside the wall. Rows of combat robots also quickly pulled the triggers of their guns, and countless ammunition was vented on the zombies outside the blocking area.

"Roar!!" The ordinary giant zombies couldn't resist this powerful vitality at all, and they were torn to pieces in an instant, bursting out with a blood mist in the sky. A ghoul zombie was swept in the leg by a Gauss cannon in the dodge, and the huge penetrating force directly amputated the ghoul, and the hapless ghoul could only lie on the ground and wait for death to come.

The bullets of the 'Ding Ding Ding Ding' electromagnetic cannon could not penetrate the defense of the Titan Zombies, and the bullets splashed bursts of sparks on its body, but the powerful kinetic energy of the countless bullets hit the Titan Zombies and could not continue to move forward.

"Gauss cannon aims at Titan zombies" With the order of the fat man on the wall, Gauss cannon began to shoot at the Titan zombies. The powerful penetrating power can only leave small holes in its body, and one by one the Titan zombies are unwilling to fall.

"Twitter!" With a loud roar from the zombie mother, a large group of Titan zombies rushed out from the distant corpse group, rushing towards the tall city wall of the blocking area with a rainbow of momentum.

"Plasma lava bombs, cover the blow!" According to the battle situation in front of him, the fat man quickly issued new orders one by one.

The 'Whoosh' Plasma Lava Bomb was launched, and countless lava missiles dragged a long tail inflammation and flew towards the Titan zombie horde with strong defense.

The moment the 'boom, boom, boom' plasma lava bomb exploded, the dark blue plasma completely covered the Titan zombie group, and many Titan zombies were burned by the plasma, rolling on the ground and howling.

However, the plasma fluid in one place soon lost its original lethality. Although the plasma weapon has huge energy and great lethality, the release speed of the high temperature is also extremely fast, and it only takes only twenty seconds to continue to produce the effect of high temperature burn.

"Build a fire domain!" As the fat man's order was given again, all the robots on the wall switched the ammunition mode of the guns, and one incendiary bomb after another began to fire at the path of the zombies, creating a high-temperature area five hundred meters wide in an instant.

'Puff~Puff~Puff~' The abomination in the zombie crowd is about to stand up at this time, like the water gun of a fire truck, spewing out strong acid. Where the strong acid was poured on, the fire was quickly extinguished, and the zombie army charged again.

PS：

This will be a new journey, and it took Xiao Wei two hours to code a chapter after he came back. In the future, I will make up the number of words in the base interface data, which means that the base interface data does not count as the word count.
