**Chương 13: Hai Mươi Năm Hy Vọng và Chờ Đợi 5600**
Cự Mãng Xà Thép khổng lồ Siberia lặng lẽ nhìn Joshua ném Mảnh Vỡ Thép đã được truyền linh hồn vào Cổng Thời Không, nó quan sát tất cả bằng sự tĩnh lặng tuyệt đối, không chút cảm xúc dao động.
Mỗi thế giới đều khác nhau, mỗi Ý Chí Thế Giới cũng vậy. Có những Ý Chí Thế Giới thích can thiệp vào văn minh và chủng tộc bên trong thân thể mình, chúng thậm chí còn tự ra tay, giúp đỡ những sinh vật đáng yêu, yếu ớt, sống đời phù du như những người phàm nhân vô giá trị đi đến thịnh vượng.
Còn có những Ý Chí Thế Giới coi việc tra tấn vạn vật là điều ác. Có thể chúng không thực sự muốn làm việc xấu, nhưng theo một nghĩa nào đó, chúng chỉ như những đứa trẻ nghịch kiến, thỉnh thoảng chọc phá, phá hoại cơ thể mình – vừa ngây thơ vừa đáng sợ.
Có hòa nhã, có lạnh lùng, tự nhiên cũng có tàn ác và vô tình. Ý Chí Thế Giới giống như những sinh vật có trí tuệ, có đủ loại hình thái.
Còn Siberia thì đặc biệt hơn nhiều. So với đồng loại “hiện diện cùng loại” năng động, thích can thiệp vào thế giới, nó lại không quan tâm đến bất cứ điều gì. Cự Mãng Xà trôi nổi trong Hư Không chỉ muốn bình lặng quan sát chúng sinh luân hồi, yên tĩnh ngủ một giấc... nhưng ngay cả mong ước đơn giản đó cũng luôn không thể thực hiện được.
“Kẻ đến từ thế giới khác.”
Cự Mãng Xà không nghỉ ngơi suốt ngàn năm nhìn pháp trận đang từ từ tiêu tán, khẽ tự thì thầm: “Hy vọng ngươi có thể đưa mọi thứ trở lại quỹ đạo... Ngươi là vị khách duy nhất trong nhiều năm sẵn sàng giúp ta.”
Và đồng thời, linh hồn của Joshua đang chìm xuống.
Xuyên qua Cổng Thời Không đầy sương mù, tiến vào lớp đệm giữa thế giới và Hư Không, chiến sĩ cảm thấy mình đang rơi, rơi không ngừng, bức màn thời không huyền bí biến hóa liên tục lay động bên cạnh, anh cảm nhận có vô số âm thanh và màu sắc đang xâm lược các giác quan của mình.
Đây là lần đầu tiên Joshua xuyên qua một rào cản thế giới xa lạ. Thường ngày, do quen thuộc với Thế Giới Mycroft, anh luôn có thể vượt qua khoảng cách này trong thoáng chốc, nhưng tại Thế Giới Siberia, do một năng lượng kỳ lạ nào đó ngăn trở, anh phải trải qua một khoảng thời gian khá dài.
Trong một vùng ánh sáng mờ ảo và năng lượng kỳ diệu, linh hồn của chiến sĩ dường như nghe thấy một “tiếng nói”.
Joshua, ngươi tự xưng là kẻ cứu thế, thực chất ngươi định cứu ai?
Ngươi từng nói, con người trên đời không cần cứu giúp, họ tự cứu lấy mình, vậy tại sao ngươi lại tự xưng là kẻ cứu thế?
Tiếng nói này rất kỳ lạ, dường như đến từ sâu thẳm trong lòng, cũng như đến từ nơi hư không. Nó khơi gợi mọi sợi dây logic yếu ớt trong tâm hồn người ta, và không ngừng đặt câu hỏi.
Joshua không suy nghĩ nhiều về nguồn gốc của câu hỏi này. Có lẽ đó là sự hoài nghi sâu thẳm trong lòng chiến sĩ dành cho chính mình, có lẽ là ma chướng phát sinh khi hình thái sinh mệnh tiến hóa đến mức này, giờ đây do phân ly giữa thể xác và linh hồn, những nghi ngờ bị ẩn giấu mới trồi lên bề mặt... nhưng những điều đó đều không quan trọng, Joshua chỉ bình tĩnh đưa ra câu trả lời của mình.
Cứu thế là một hành động, còn kẻ cứu thế là một thái độ.
Đặt mình lên trên cả thế giới, từ trên cao nhìn xuống mà “cứu”, tư tưởng này kiêu ngạo và viển vông... nhưng giúp đỡ người khác không đi đến hủy diệt, thực chất chỉ cần động tay, làm, bắt đầu hành động là đủ.
Cứu thế đối với Joshua, chẳng qua là làm một việc nên làm, giống như người có tâm thiện sẽ giúp người đi đường chỉ đường, giúp người sắp ngã hay đã ngã đứng dậy. Lực lượng của chiến sĩ đã đến mức này, nên tâm thiện của anh có thể làm được những việc như vậy, hoàn toàn không cần bất kỳ danh hiệu cao siêu nào.
Anh tự xưng là kẻ cứu thế, chỉ là để nêu lên một sự thật, nhưng từ đầu đến cuối, Joshua vẫn là chiến sĩ, và chỉ đơn thuần là chiến sĩ.
Bức màn thời không biến hóa biến mất.
Mảnh Vỡ Thép màu tím xanh rơi xuống từ tầng cao nhất của thế giới. Nó xuyên phá vô tầng mây, rơi xuống một mảnh đất liền hình thoi. Có thể thấy, trên lục địa đầy hoang vu, chỉ lác đác những đốm xanh nhỏ rải rác khắp mọi nơi, còn ở trung tâm lục địa, có một nhóm những công trình bằng sắt thép đang ầm ầm vận hành, và ở chính giữa chúng, một ngọn tháp xoắn ốc khổng lồ, cao vút đến mức dường như xuyên thủng tầng mây, đang đứng sừng sững giữa thế giới...
【Nhật ký công việc, ngày thứ 3739: Cách đây vài ngày, tôi đã cởi hết quần áo, dùng nước lạnh tạt lên người, đầu tôi bắt đầu nóng lên, đây chính là “cảm lạnh” được nhắc đến trong sách... Soul Puppet [Hồn Cơ Binh] bước vào phòng sửa chữa, đưa tôi đi. Lần đầu tiên tôi rời khỏi hành.lang khu bảo trì, chúng đưa tôi đến khu y tế, bên trong là những người mặt vô cảm tương tự, họ chẩn đoán cho tôi, cung cấp thuốc, tiêm thuốc, còn tôi nhân cơ hội này quan sát xung quanh... Khi tôi đang tiêm, lại có một đứa trẻ bị Soul Puppet dẫn vào. Nó đưa đứa trẻ vào phòng phẫu thuật cuối cùng... Binh cơ đi ra, tay cầm hai cái hộp, nhưng đứa trẻ thì không còn nữa. Hộp được đặt lên tủ bên cạnh, tôi thấy những tủ xung quanh đều chất đầy những hộp tương tự, trên đó viết là... ‘Siêu Năng Đơn Nguyên’? Chắc là từ này.
Trở về phòng sửa chữa, tôi phát hiện lại có thêm một Linh Hồn Cốt Lõi. Tôi đại khái hiểu rồi, trong lòng bình thản một cách bất ngờ. Tôi tưởng mình sẽ phát điên, nhưng chẳng lẽ bây giờ tôi không điên sao? Ha ha.】
【Nhật ký công việc, ngày thứ 4000: Một con số đẹp tròn trịa, tôi bắt đầu dần dần thoát khỏi trạng thái suy sụp. Dù sao tôi vẫn sống, sống là hy vọng, dù cô đơn đến đâu, dù vô vị đến đâu, tôi vẫn tốt hơn những thường dân trong khu nuôi trồng, hay những đứa trẻ bị đưa vào phòng phẫu thuật...unknown: unknown
